[0070] It should be noted that, in order to clearly illustrate the structure of each component, hatching is omitted in some cross-sectional views.

[0071] Wastewater discharged from laundry processing equipment often contains impurities such as microplastics. Microplastics are plastic particles, fibers, or films with a diameter of less than 5mm. These microplastics are generally non-biodegradable and difficult to filter out. Although wastewater is filtered and separated by municipal sewage treatment systems before discharge, more than half of these microplastics still enter rivers and oceans, ultimately entering the human body through the food chain and posing a health risk.

[0072] Currently, related laundry treatment equipment uses a filter at the drain outlet to filter impurities from the wastewater discharged from the laundry treatment equipment, thereby protecting the blades of the drainage pump. However, the filtration accuracy of existing filters is between 5mm and 10mm, and the filtering effect on microplastics is not significant. In addition, existing filters also have the following problems.

[0073] On the one hand, existing filter devices have complex structures, making installation and removal of the filter element cumbersome during maintenance. On the other hand, existing filter devices are prone to clogging, and when clogged, they fail to promptly notify the user to replace or clean the filter device, resulting in reduced drainage efficiency and impacting the reliability of the laundry processing equipment.

[0074] To solve the above problems, with reference to Figure 1, some embodiments of the present disclosure provide a clothing processing device 1000, which includes a housing 100, a cylinder and a filter device 10. The filter device 10 is connected to the drain outlet of the cylinder and is configured to filter microplastics in the sewage discharged from the housing 100. A first sub-filter element and a second sub-filter element are also provided inside the filter device 10. In this way, the water to be filtered is filtered twice, thereby improving the filtering effect of the filter device 10. The filter device also includes a warning component. In the event of blockage inside the filter device, the filter component can be protruded from the outside of the filter device under the action of water pressure to remind the user. In this way, the reliability of the clothing processing device 1000 is ensured.

[0075] It should be noted that the clothing processing device 1000 can be a clothing processing device, a drying machine, or a washer-dryer.

[0076] In some embodiments, the housing 100 is configured as the outer shell of the laundry processing apparatus 1000. The housing 100 is a hollow structure having an interior space. Other components of the laundry processing apparatus 1000, such as circuit structures, air duct structures, drive mechanisms, and drainage structures, may be located in the interior space.

[0077] In some embodiments, the drum is disposed in the interior space of the housing 100 and is configured to wash or dry clothes. The drum has a clothes receiving cavity with an opening on one side, and clothes are put into the clothes receiving cavity through the drum opening for washing or drying.

[0078] The drum is also provided with a drain outlet configured to drain wastewater generated by washing or drying clothes within the drum. If the axis of the drum is arranged along the front-to-back direction of the housing 100, the laundry processing apparatus 1000 may be a drum-type laundry processing apparatus 1000. If the axis of the drum is arranged along the top-to-bottom direction of the housing 100, the laundry processing apparatus 1000 may be a pulsator-type laundry processing apparatus. Some embodiments of the present disclosure are described using a drum-type laundry processing apparatus as an example.

[0079] In some embodiments, the laundry processing device 1000 further includes a door. The door is configured to seal the opening of the drum during laundry washing, thereby maintaining a sealed chamber during laundry washing. The door is connected to the housing 100 and is positioned corresponding to the opening of the drum. A glass door may also be provided on the door to facilitate observation of the laundry process.

[0080] In some embodiments, the drum body includes an outer drum and an inner drum. The inner drum is hollow to form the clothing receiving chamber and is provided with a clothing loading port. The inner drum is disposed within the inner cavity of the outer drum, which is disposed within the housing 100. A door covers the clothing loading port of the inner drum, thereby forming a sealed space in the clothing receiving chamber. The inner drum has an opening disposed in the peripheral wall of the inner drum. The inner drum communicates with the inner cavity of the outer drum via the opening, so that waste washing water can be discharged into the outer drum through the opening. A drain outlet may be provided at the bottom of the outer drum.

[0081] In some embodiments, the laundry processing apparatus 1000 further includes a first drain pipe 200, which is disposed outside the tub. One end of the first drain pipe 200 is connected to the interior of the tub, that is, one end of the first drain pipe 200 is connected to the laundry receiving chamber, and the other end of the first drain pipe 200 extends outside the housing 100, thereby draining the sewage in the laundry receiving chamber out of the housing 100.

[0082] In some embodiments, the filter device 10 is connected to the first drain pipe 200 and is configured to filter microplastics in the wastewater discharged from the clothing treatment device 1000. The filter device 10 is configured to filter the wastewater in the clothing receiving chamber. After the wastewater is discharged from the housing 100 through the first drain pipe 200, it can enter the filter device 10 for filtration and be discharged after filtration. This allows the filtration of impurities such as microplastics in the wastewater, reducing the content of microplastics in the wastewater discharged into the environment and minimizing the damage to the ecological environment caused by microplastics.

[0083] 2 to 6 , the filter device 10 includes a housing 11. The housing 11 serves as the outer shell of the filter device 10. A receiving portion 111 is formed within the housing 11. The receiving portion 111 is configured to house the main components of the filter device 10. For example, the receiving portion 111 is a receiving tank. The receiving portion 111 opens toward the top of the housing 11 to receive and filter water introduced from the outside.

[0084] It should be noted that the water to be filtered may be sewage discharged from the first drain pipe 200 of the laundry processing apparatus 1000. In this case, the filter device 10 is a part of the laundry processing apparatus 1000, but can be provided independently of the main body of the laundry processing apparatus 1000, for example, hung outside the housing 100 of the laundry processing apparatus 1000.

[0085] 5 and 6 , the housing 11 includes a housing body 110, a water inlet 121, and a water outlet 122. The accommodating portion 111 is formed inside the housing body 110. The water inlet 121 and the water outlet 122 are disposed on the outer wall of the housing body 110 and are both connected to the accommodating portion 111.

[0086] The water inlet 121 is configured to connect to an external structure to introduce external filtered water into the accommodating portion 111 for filtration. For example, the water inlet 121 is a water inlet pipe. The water inlet 121 can be connected to the first drain pipe 200 of the laundry treatment device 1000. After being filtered in the accommodating portion 111, the filtered water becomes filtered water.

[0087] The water outlet 122 is configured to discharge the filtered water out of the accommodating portion 111. For example, the water outlet 122 is a water outlet pipe. The filtration device 10 also includes a second drain pipe 102 (see FIG. 1 ), which is configured to discharge the filtered water discharged from the water outlet 122 into a municipal sewage treatment system. The water outlet 122 can be in communication with the second drain pipe 102 of the filtration device 10.

[0088] In some embodiments, the water inlet 121 is spaced apart and positioned above the water outlet 122. For example, the water inlet 121 can be positioned at the top of the housing body 110 and communicate with the top space of the accommodating portion 111, thereby allowing filtered water to be introduced into the accommodating portion 111 for filtration. The water outlet 122 can be positioned at the bottom of the housing body 110 and communicate with the bottom space of the accommodating portion 111, thereby allowing filtered water to be fully discharged to the exterior of the housing 11.

[0089] In some embodiments, a receiving portion 112 is formed at the rear of the housing body 110. The receiving portion 112 is configured to accommodate the water inlet 121 and an external pipe (e.g., the first drain pipe 200) configured to communicate with the water inlet 121. For example, the receiving portion 112 is a receiving groove. The rear portion and bottom of the receiving portion 112 are both opened.

[0090] 3A and 3B , the housing 11 further includes a rear cover 13, which can be disposed over the rear opening of the receiving portion 112. A pipe from the outside, configured to communicate with the water inlet 121, extends from the bottom opening of the receiving portion 112 into the receiving portion 112.

[0091] It should be noted that, when the filter device 10 is disposed outside the housing 100, the filter device 10 can be fixed to a wall via the rear cover 13 to facilitate connecting the water outlet 122 to the second drain pipe 102. For example, a fastener can be provided on the rear cover 13 to securely connect to the wall.

[0092] 2 and 3A , the housing body 110 further includes a mating portion 113, which can be disposed on the inner wall of the receiving portion 112. Two mating portions 113 can be provided, and the two mating portions 113 can be disposed opposite each other on two side walls of the receiving portion 112. For example, the mating portion 113 is a protrusion.

[0093] 3B , the back cover 13 includes a back cover body 130 and a fourth engaging portion 131. The fourth engaging portion 131 is disposed on the back cover body 130 and is configured to engage with the mating portion 113, thereby securing the back cover 13 to the housing 11. Two fourth engaging portions 131 can be arranged opposite each other, with each engaging with a corresponding mating portion 113. For example, the fourth engaging portion 131 can be a hook.

[0094] 7 , 8 and 18 , the filter device 10 further includes an end cap 14 disposed at the top opening of the accommodating portion 111 and configured to seal the top opening of the accommodating portion 111 to prevent leakage of unfiltered sewage.

[0095] The end cap 14 can be detachably fixed to the opening of the accommodating portion 111, with a portion of the end cap 14 located inside the accommodating portion 111 and another portion of the end cap 14 exposed outside the accommodating portion 111. In this way, the user can remove the end cap 14 through the portion exposed outside the accommodating portion 111 to clean microplastics such as lint in the accommodating portion 111.

[0096] In some embodiments, the end cap 14 includes an end cap body 140 and a third lifting portion 141 . The third lifting portion 141 is disposed on the top of the end cap body 140 . The user can remove the end cap 14 from the accommodating portion 111 through the third lifting portion 141 .

[0097] It is understood that the shape of the end cap 14 can match the shape of the opening of the accommodating portion 111. Thus, when the end cap 14 is positioned at the opening of the accommodating portion 111, the end cap 14 will seal the top opening of the accommodating portion 111, thereby achieving a seal on the accommodating portion 111. Referring to Figures 7 and 18, when the opening of the accommodating portion 111 is circular, the end cap 14 can be a circular end cap 14.

[0098] In some embodiments, referring to Figures 7 and 8, the end cap body 140 further includes a second water guide 143 and at least one first water inlet 142. The first water inlet 142 is provided on one side of the end cap body 140, and the water to be filtered is adapted to enter the end cap 14 through the first water inlet 142. For example, the second water guide 143 is a water guide groove. The opening of the second water guide 143 is downward, that is, the opening of the second water guide 143 is arranged toward the interior of the accommodating portion 111. The water to be filtered is adapted to enter the interior of the accommodating portion 111 through the opening of the second water guide 143 for filtration.

[0099] For example, the end cover body 140 includes a second top wall 1401 and a second side wall 1402 . The second side wall 1402 is arranged around the second top wall 1401 , so that the second top wall 1401 and the second side wall 1402 together form a second water guide portion 143 opening downward.

[0100] It is understood that the third lifting portion 141 can be disposed on a side of the second top wall 1401 away from the interior of the accommodating portion 111. The first water inlet 142 can be disposed on the second top wall 1401, the second side wall 1402, or both the top and side walls of the end cover 14. In this case, the filtered water enters the end cover 14 through the first water inlet 142, and can also enter the second water guide portion 143 through the first water inlet 142.

[0101] In some embodiments, the at least one first water inlet 142 includes a plurality of first water inlets 142 , and the plurality of first water inlets 142 may be spaced apart along the circumference of the end cover 14 , that is, spaced apart along the circumference of the second sidewall 1402 .

[0102] Referring to Figures 10 and 18 , the filter device 10 further includes a filter element 15. The filter element 15 is disposed within the accommodating portion 111 and is located on a side of the end cap 14 that is adjacent to (i.e., below) the interior of the accommodating portion 111. For example, the filter element 15 is entirely located within the accommodating portion 111. The filter element 15 is configured to filter wastewater introduced into the accommodating portion 111, so that microplastics such as lint are retained in the filter element 15 after filtration.

[0103] In some embodiments, a filter portion 151 is formed within the filter element 15. For example, the filter portion 151 is a filter tank. The top of the filter portion 151 is open. Sewage introduced into the accommodating portion 111 through the water inlet portion 121 can enter the filter portion 151 from the top, and then be filtered through the surrounding side walls and bottom wall of the filter portion 151. The filtered water can then pass through the surrounding side walls and bottom wall of the filter portion 151, enter the accommodating portion 111 area outside the filter portion 151, and then be discharged to the outside of the housing 11 through the water outlet portion 122.

[0104] In some embodiments, the bottom of the filter element 15 is spaced apart from the bottom sidewall of the accommodating portion 111. Therefore, the water filtered and filtered through the bottom wall of the filter portion 151 can flow to the bottom area of ​​the accommodating portion 111 and then discharged to the outside of the housing 11 through the water outlet 122.

[0105] In some embodiments, the periphery of the filter element 15 is spaced apart from the peripheral sidewalls of the accommodating portion 111. Therefore, water filtered and passed through the peripheral sidewalls of the filter portion 151 can flow through the gap between the periphery of the filter element 15 and the peripheral sidewalls of the accommodating portion 111 to the bottom area of ​​the accommodating portion 111, and then be discharged to the outside of the housing 11 through the water outlet 122.

[0106] It should be noted that, in other embodiments, the water to be filtered may be filtered only through the peripheral side wall of the filter portion 151 , or may be filtered only through the bottom wall of the filter portion 151 .

[0107] 10 and 11 , in some embodiments, the filter element 15 can be disposed in contact with the end cap 14. Of course, in other embodiments, the filter element 15 can be spaced apart from the end cap 14. The opening of the filter portion 151 can be disposed toward the opening at the bottom of the second water guide portion 143, thereby allowing water within the second water guide portion 143 to flow through the opening at the bottom of the second water guide portion 143 under the action of gravity into the filter portion 151 for filtration.

[0108] It should be noted that the filter element 15 can be cylindrical, and in this case, the accommodating portion 111 can also be cylindrical (see FIG18 ). A gap is formed between the outer wall of the filter element 15 and the inner wall of the accommodating portion 111 to ensure that water discharged from the filter portion 151 can flow down through the gap, thereby preventing the inner wall of the accommodating portion 111 from obstructing the flow of water discharged from the filter portion 151.

[0109] Referring to Figure 10 , in some embodiments, the filter element 15 includes a filter frame 152 and a first filter screen 153. The filter frame 152 forms the skeleton of the filter element 15, and multiple hollow areas are formed on the sidewalls and bottom wall of the filter frame 152. The first filter screen 153 is disposed in the hollow areas and can be configured to filter wastewater discharged from the laundry treatment device 1000 to remove microplastics in the wastewater.

[0110] The filter frame 152 and the first filter screen 153 constitute the filter section 151. The water in the filter section 151 can be filtered through the first filter screen 153 at each hollow area, pass through the filter holes on the first filter screen 153 and enter the accommodating portion 111, thereby filtering the microparticles in the sewage, reducing the discharge of microparticles into the environment, and further reducing the damage of microparticles to the ecological environment.

[0111] It is understandable that because synthetic clothing contains microplastics such as polyester and acrylic fibers, and most microplastics are non-biodegradable, the wastewater discharged from clothing processing equipment 1000 contains a high level of microplastics. Microplastics refer to plastic fragments or particles with a diameter of less than 5 mm.

[0112] In some embodiments, the aperture size of the first filter 153 is smaller than a preset aperture size, thereby enabling the first filter 153 to fully filter the "microplastics".

[0113] 11 and 12 , the filter device 10 further includes a cleaning member 16, which is disposed at the bottom of the end cap body 140. The top of the cleaning member 16 can be disposed within the end cap body 140, that is, the top of the cleaning member 16 is disposed within the second water guide portion 143. At this time, the outer peripheral wall of the top of the cleaning member 16 can be in contact with the inner peripheral wall of the second water guide portion 143, thereby allowing the water in the second water guide portion 143 to fully enter the cleaning member 16.

[0114] For example, the outer peripheral wall of the top of the cleaning member 16 is provided with an external thread, and the inner peripheral wall of the second water guide portion 143 is provided with an internal thread, and the cleaning member 16 and the second water guide portion 143 are connected through threads.

[0115] 13 and 14 , the cleaning member 16 is provided with at least one water guide hole 161. The water guide hole 161 is configured to guide water in the cleaning member 16 toward the inner wall of the filter portion 151, thereby flushing the inner wall of the filter portion 151 through the impact of the water flow. The water guide hole 161 is provided at the bottom of the cleaning member 16.

[0116] The depth direction of the water guide hole 161 is inclined relative to the vertical direction toward the inner wall of the filter portion 151 , that is, the depth direction of the water guide hole 161 is inclined toward a direction away from the center of the cleaning component 16 .

[0117] It should be noted that, when the filter device 10 is placed vertically, the height direction of the cleaning member 16 (the up-down direction as shown in FIG. 14 ) is the vertical direction.

[0118] 14 , the depth direction of the water guide hole 161 forms an angle A with the vertical direction. If there are multiple water guide holes 161, the angles A between the depth direction and the vertical direction of the multiple water guide holes 161 can be the same or different. In FIG14 , the angles A between the depth direction and the vertical direction of the multiple water guide holes 161 are shown as being the same.

[0119] It should be noted that the angle A may range from 20° to 60°. For example, the angle A is 20°, 30°, 40°, 50°, or 60°.

[0120] In summary, in the filter device 10 provided in some embodiments of the present disclosure, when the water to be filtered flows from the cleaning part 16 into the filter part 151, due to the setting of the water guide hole 161, the water to be filtered will flush the inner wall of the filter part 151, which can avoid debris from clogging the filter element 15 and ensure the filtering effect of the water to be filtered.

[0121] Continuing with Figure 14 , in some embodiments, the cleaning member 16 includes a first bottom wall 162, a first side wall 163, and a cleaning portion 164. The first bottom wall 162 is disposed around the first side wall 163 to form the cleaning portion 164. A water guide hole 161 is disposed in the first bottom wall 162. After water in the end cap 14 enters the cleaning portion 164, it flows through the water guide hole 161 into the filter portion 151.

[0122] It is understandable that the shape of the cleaning member 16 can match the shape of the bottom of the end cover 14. For example, the first bottom wall 162 is configured as a circle, and the first side wall 163 is configured as a circular ring.

[0123] 11 and 14 , when the first sidewall 163 of the cleaning member 16 abuts against the inner wall of the second water guide portion 143, the second water guide portion 143 and the cleaning portion 164 together form a water guide cavity 17. The first water inlet 142 is located on the side of the cleaning member 16 near (i.e., above) the second top wall 1401. Thus, after the filtered water enters the water guide cavity 17 through the first water inlet 142, it is discharged through the water guide hole 161 and enters the filter portion 151, thereby ensuring effective filtration of the filtered water.

[0124] In some embodiments, the water guide holes 161 may be divided into at least two groups, each group of water guide holes 161 includes a plurality of water guide holes 161 , and the plurality of water guide holes 161 in each group are spaced apart from each other.

[0125] The multiple water guide holes 161 in each group can be arranged in a ring shape. The ring shape can be a closed shape, such as a circle, an ellipse, a rectangle, etc. When the first bottom wall 162 is arranged in a circular shape, the multiple water guide holes 161 in each group can also be arranged in a circular shape. In this case, each water guide hole 161 is arranged in an arc shape.

[0126] 13 and 14 , the water guide holes 161 are divided into two groups. Each group of water guide holes 161 includes four water guide holes 161 . The four water guide holes 161 are spaced apart from each other.

[0127] The two groups of water guide holes 161 can be arranged in a ring with intervals between them. In this case, the depth direction of the water guide holes 161 is inclined relative to the vertical direction, toward the outside of the ring. If the ring formed by the two groups of water guide holes 161 is circular, the two circles can be concentrically arranged with different radii. In this case, the depth direction of the water guide holes 161 is inclined away from the center of the circle.

[0128] It is understood that by providing multiple groups of water guide holes 161, water in the cleaning section 164 can be quickly introduced into the filter section 151, avoiding the problem of water obstruction in the cleaning section 164. By arranging the groups of water guide holes 161 in a ring shape, the water guided by the water guide holes 161 is diffused in all directions, thereby achieving a comprehensive flushing of the inner wall of the filter section 151, thereby improving the filtration efficiency of the filter device 10 and the flushing effect of the filter element 15.

[0129] 14 , in some embodiments, the cleaning member 16 further includes a first connecting post 165 . For example, the center of the first bottom wall 162 of the cleaning member 16 is convex downward to form the first connecting post 165 . The water guide holes 161 are provided around the first connecting post 165 .

[0130] 7 and 8 , in some embodiments, the end cap 14 further includes a first water diversion portion 21 formed on a sidewall of the end cap 14. A first water inlet 142 is at least partially disposed in the first water diversion portion 21. The first water diversion portion 21 communicates with the second water diversion portion 143 via the first water inlet 142. For example, the first water diversion portion 21 is a water diversion trough.

[0131] The first water guide portion 21 may be disposed along the circumference of the end cover body 140 . In the case where the end cover body 140 includes a plurality of first water inlets 142 , the plurality of first water inlets 142 are all in communication with the first water guide portion 21 .

[0132] 18 and 19 , when the end cover 14 is disposed in the accommodating portion 111 , the opening of the first water diversion portion 21 is in contact with the side wall of the accommodating portion 111 to seal the first water diversion portion 21 .

[0133] In some embodiments, the housing 11 further includes a second water inlet 1211 disposed on a sidewall of the housing 11. The second water inlet 1211 connects the water inlet portion 121 and the first water diversion portion 21. The second water inlet 1211 is configured to direct external water into the first water diversion portion 21, and then into the second water diversion portion 143 through the first water inlet 142.

[0134] It is understood that in an embodiment in which the first water diversion portion 21 is not provided, water from the outside is suitable for entering the second water diversion portion 143 through the water inlet portion 121, the second water inlet 1211, and the first water inlet 142. In an embodiment in which the first water diversion portion 21 is provided, the first water diversion portion 21 and the second water diversion portion 143 are both part of the internal space of the end cover 14. In this case, water from the outside is introduced into the end cover 14 through the water inlet portion 121, the second water inlet 1211, the first water diversion portion 21, and the first water inlet 142.

[0135] The provision of the first water diversion portion 21 enables external water to enter the end cover through the plurality of first water inlets 142 circumferentially of the end cover body 140 , thereby increasing the rate at which external water enters the end cover 14 .

[0136] 9 , in some embodiments, the end cap 14 further includes a first sealing portion 144 and a second sealing portion 145. For example, the outer wall of the end cap body 140 is raised to form the first sealing portion 144 and the second sealing portion 145. The first sealing portion 144 and the second sealing portion 145 extend along the circumference of the end cap body 140, and the first sealing portion 144 and the second sealing portion 145 are spaced apart in the height direction of the end cap body 140 to form the first water diversion portion 21. The first water inlet 142 is located between the first sealing portion 144 and the second sealing portion 145.

[0137] The first sealing portion 144 and the second sealing portion 145 may have the same protrusion height relative to the outer wall of the end cover body 140. When the end cover 14 is disposed within the accommodating portion 111, the outer sides of the first sealing portion 144 and the second sealing portion 145 are configured to abut against the inner wall of the accommodating portion 111, thereby sealing the opening at the end of the first water diversion portion 21.

[0138] Furthermore, end cap 14 further includes a first seal 1461 and a second seal 1471. First seal 1461 is disposed between the inner wall of filter portion 151 and first seal portion 144, and second seal 1471 is disposed between the inner wall of filter portion 151 and second seal portion 145. First seal 1461 and second seal 1471 are flexibly disposed. First seal 1461 is configured to seal the gap between filter portion 151 and first seal portion 144, and second seal 1471 is configured to seal the gap between filter portion 151 and second seal portion 145.

[0139] It is understood that when the first sealing portion 144 and the second sealing portion 145 contact the inner wall of the accommodating portion 111, a certain gap will exist between the first sealing portion 144 and the second sealing portion 145 and the inner wall of the accommodating portion 111 due to the relatively hard material. The first sealing member 1461 and the second sealing member 1471 are configured to be flexible. When the first sealing member 1461 and the second sealing member 1471 contact the inner wall of the accommodating portion 111, they can seal the gap between the first sealing portion 144 and the second sealing portion 145 and the inner wall of the accommodating portion 111.

[0140] In some embodiments, the first sealing portion 144 has a first engaging portion 146 disposed on the outer side of the first sealing portion 144. The second sealing portion 145 has a second engaging portion 147 disposed on the outer side of the second sealing portion 145. A first sealing member 1461 may be disposed within the first engaging portion 146, and the second sealing portion 145 may be disposed within the second engaging portion 147. The first sealing member 1461 protrudes relative to the opening of the first engaging portion 146, and the second sealing member 1471 protrudes relative to the opening of the second engaging portion 147, so that the first sealing member 1461 contacts the inner wall of the accommodating portion 111, and the second sealing member 1471 contacts the inner wall of the accommodating portion 111.

[0141] Referring to Figures 10 to 17 , in some embodiments, the filter device 10 includes not only the housing 11, end cap 14, and filter element 15 described above, but also an overflow member 26. The overflow member 26 is configured to filter the water to be filtered in the event that the filter element 15 becomes clogged. The overflow member 26 is sleeved on the end cap 14 and disposed around the outer periphery of the filter element 15. The overflow member 26 can be disposed at the bottom of the end cap 14. Referring to Figure 15 , the overflow member 26 can be disposed below the second sealing portion 145. For example, the overflow member 26 is an overflow ring.

[0142] 17 , the inner wall of the overflow member 26 may be provided with internal threads, and the outer wall of the bottom of the end cap 14 may be provided with external threads. In this way, the overflow member 26 can be screwed onto the bottom of the end cap 14. At this point, the top of the overflow member 26 can abut against the bottom wall of the second sealing portion 145.

[0143] 18 and 19 , the outer periphery of the overflow member 26 abuts against the inner wall of the accommodating portion 111 , and the overflow member 26 , the inner wall of the accommodating portion 111 , and the end cover 14 (eg, the second sealing portion 145 ) together form a first overflow chamber 27 .

[0144] 16 and 17 , the end cap 14 further includes a first water outlet 148 and at least one second water outlet 149. The first water outlet 148 may be an opening of the second water guide portion 143, i.e., an opening of the bottom wall of the end cap 14. The second water outlet 149 is disposed on the bottom wall of the first water guide portion 21. That is, the second water outlet 149 is disposed on the second sealing portion 145. The first water outlet 148 is configured to direct water in the second water guide portion 143 into the filter portion 151. The second water outlet 149 is configured to direct water in the end cap 14 into the first overflow chamber 27.

[0145] It can be understood that the first water guide portion 21 and the second water guide portion 143 are both internal spaces of the end cover 14 .

[0146] 18 and 19 , the second water outlet 149 is in communication with the first overflow chamber 27. Thus, even if the filter element 15 becomes clogged, water within the end cap 14 can flow into the first overflow chamber 27 through the second water outlet 149. The overflow element 26 also has a water-permeable filtering function. Water within the first overflow chamber 27 can pass through the overflow element 26 for filtration, and the filtered water can then enter the accommodating portion 111 and be discharged from the accommodating portion 111.

[0147] It is understood that if the filter element 15 becomes clogged (i.e., the filter portion 151 is blocked), the external water flow continuously guides water into the filter portion 151, causing the filter portion 151 to be filled with water and thus fill the end cap 14. At this time, the water pressure in the end cap 14 will be greater than the preset water pressure, and the water will enter the first overflow chamber 27. After being filtered by the overflow member 26, the water in the first overflow chamber 27 enters the accommodating portion 111 and is discharged from the accommodating portion 111.

[0148] It should be noted that when the water pressure in the end cover 14 is lower than the preset water pressure, the water in the end cover 14 will only be introduced into the filter portion 151 from the first water outlet 148 , and will not be introduced into the first overflow chamber 27 from the second water outlet 149 .

[0149] In some embodiments, the filter device 10 further includes a control valve disposed at the second water outlet 149 and configured to open or close the second water outlet 149. When the filter portion 151 is blocked and the water pressure at the control valve is greater than a preset water pressure, the control valve opens the second water outlet 149 to direct the water in the end cap 14 into the first overflow chamber 27. When the water pressure at the control valve is less than the preset water pressure, the control valve closes the second water outlet 149 to allow all the water in the end cap 14 to enter the filter portion 151 from the first water outlet 148.

[0150] Of course, in other embodiments, in order to allow the water in the end cap 14 to be discharged from the second water outlet 149 only when the water pressure in the end cap 14 is greater than a preset water pressure, the peripheral wall of the second water outlet 149 can be configured to be flexible and initially closed. In this way, when the water pressure in the end cap 14 is greater than the preset water pressure, the water in the end cap 14 is squeezed through the second water outlet 149 and thus discharged from the second water outlet 149.

[0151] In summary, the overflow member 26 allows the water in the end cap 14 to flow into the accommodating portion 111 through the overflow member 26 when the filter element 15 is blocked. This prevents the problem of sewage not being filtered and drainage being poor due to a blockage in the filter portion 151. Furthermore, while maintaining the filtering effect of the filter device 10, the drainage effect of the laundry processing apparatus 1000 is also guaranteed.

[0152] In order to ensure that the filter device 10 can still filter and drain sewage when the filter element 15 is clogged, the at least one second water outlet 149 includes a plurality of second water outlets 149. The plurality of second water outlets 149 can be spaced apart in the circumferential direction of the second sealing portion 145, so that when the water pressure in the end cover 14 is greater than the preset water pressure, the water in the end cover 14 can be fully discharged through the second water outlets 149.

[0153] In some embodiments, the filter device 10 further includes a third seal 265 , which is disposed between the accommodating portion 111 and the overflow member 26 . The third seal 265 is configured to seal the gap between the filter portion 151 and the overflow member 26 .

[0154] 19 to 22 , the outer peripheral wall of the overflow member 26 is provided with a third engaging portion 261, with the opening of the third engaging portion 261 facing away from the center of the overflow member 26. A third sealing member 265 is flexible and partially located within the third engaging portion 261. The top of the third sealing member 265 is raised relative to the opening of the third engaging portion 261, allowing the third sealing member 265 to abut against the inner wall of the accommodating portion 111, thereby sealing the gap between the overflow member 26 and the inner wall of the accommodating portion 111.

[0155] 20 to 22 , in some embodiments, the overflow member 26 includes a connecting portion 262 and a third sealing portion 263. The third sealing portion 263 is provided to protrude relative to the connecting portion 262 and extends along the circumference of the connecting portion 262. The connecting portion 262 is sleeved on the end cover 14, and the third sealing portion 263 abuts against the inner wall of the accommodating portion 111.

[0156] It is understood that the inner wall of the connecting portion 262 is provided with an internal thread, and the outer wall of the bottom of the end cap 14 is provided with an external thread, so that the connecting portion 262 is screwed onto the external thread on the outer wall of the end cap 14 via the internal thread to achieve relative fixation. The third engaging portion 261 is provided on a side of the third sealing portion 263 away from the connecting portion 262, and the third sealing member 265 is provided between the inner wall of the accommodating portion 111 and the third sealing portion 263.

[0157] In some embodiments, the third sealing portion 263 is provided with at least one second filter portion 264, with the opening of the second filter portion 264 facing (i.e., upward) the first overflow chamber 27. For example, the at least one second filter portion 264 includes a plurality of second filter portions 264, which are spaced apart circumferentially around the third sealing portion 263. In this case, the second filter portion 264 constitutes a portion of the first overflow chamber 27.

[0158] Referring to Figures 19, 21, and 22, the third sealing portion 263 further includes a third filter 2631, which is configured to filter water within the first overflow chamber 27. The third filter 2631 is disposed at the bottom of the second filter portion 264 and forms the bottom wall of the second filter portion 264. Water within the first overflow chamber 27 is filtered through the first filter 153 and flows into the accommodating portion 111. At this point, since the overflow member 26 also has a filtering function, the first overflow chamber 27, where the overflow member 26 is located, and the filter portion 151 jointly function as a filtering chamber.

[0159] 11 and 12 , in some embodiments, the filter element 15 includes a first sub-filter element 15A and a second sub-filter element 15B, and the second sub-filter element 15B is spaced apart and arranged on the periphery of the first sub-filter element 15A, that is, the first sub-filter element 15A and the second sub-filter element 15B are spaced apart and arranged inside and outside.

[0160] The first sub-filter element 15A forms a first sub-filter portion 151A, and the second sub-filter element 15B forms a second sub-filter portion 151B. The first sub-filter element 15A is spaced apart from the second sub-filter portion 151B, and the filter holes of the second sub-filter element 15B are smaller than the filter holes of the first sub-filter element 15A.

[0161] 11 and 12 , a cleaning member 16 is provided within the filter device 10. The water guide holes 161 of the cleaning member 16 can be configured to direct water in the end cap 14 toward the inner wall of the first sub-filter portion 151A to clean the inner wall of the first sub-filter portion 151A. The cleaning member 16 can be provided at the top opening of the first sub-filter portion 15A or at the top opening of the second sub-filter portion 15B.

[0162] It is understood that the water introduced into the end cap 14 through the water inlet 121 first enters the first sub-filter 151A, where the first sub-filter 15A performs an initial filtration of microplastic particles in the sewage. The water filtered by the first sub-filter 151A then enters the second sub-filter 151B, where it is further filtered to remove microplastic particles in the sewage. The second sub-filter 151B directs the filtered water into the accommodating portion 111, where it is discharged from the housing 11. This achieves secondary filtration of the water, improving the filtration efficiency of the filtration device 10 for sewage.

[0163] It should be noted that, in other embodiments, the filter element 15 may also include only the first sub-filter element 15A. In this case, the filter element 15 may include only the second sub-filter element 15B.

[0164] In combination with the embodiment of the overflow member 26 , the water discharged through the overflow member 26 will enter the gap between the outer wall of the second sub-filter member 15B and the inner wall of the accommodating portion 111 , and then flow to the bottom of the accommodating portion 111 .

[0165] In some embodiments, referring to FIG4 , the housing 11 is further provided with an observation window 116 , which is disposed on a sidewall of the housing 11 . The observation window 116 is made of a transparent material. This allows the user to observe the water level within the accommodating portion 111 through the observation window 116 , thereby determining whether the filter 151 is clogged or about to become clogged, and promptly reminding the user to replace the filter element 15 or clean the filter 151. For example, the observation window 116 extends along the height of the housing 11 .

[0166] Referring to Figures 23 to 25A , in some embodiments, the filter element 15 is detachably disposed within the accommodating portion 111. Referring to Figures 25B to 27 , the filter element 15 further includes a first support member 157, which is disposed on the outer peripheral wall of the filter frame 152 and extends outwardly along the circumference of the filter frame 152. For example, the first support member 157 is disposed around the periphery of the top end of the filter element 15, with the outer peripheral wall of the first support member 157 abutting against the peripheral sidewall of the accommodating portion 111, thereby spacing the outer peripheral wall of the filter element 15 from the peripheral sidewall of the accommodating portion 111.

[0167] In this way, the water filtered and passed through the peripheral side wall of the filter portion 151 can flow to the bottom area of ​​the accommodating portion 111 through the gap between the outer periphery of the filter element 15 and the peripheral side wall of the accommodating portion 111, and then be discharged to the outside of the shell 11 through the water outlet portion 122.

[0168] In some embodiments, referring to FIG. 26 , the housing 11 further includes a second support member 118 disposed on the peripheral sidewall of the accommodating portion 111. The inner edge of the first support member 157 is connected to the outer peripheral wall of the filter element 15, and the outer edge of the first support member 157 is configured to support the top surface of the second support member 118. In this way, the filter element 15 can be detachably mounted on the second support member 118 via the first support member 157, with the outer peripheral wall of the filter element 15 and the peripheral sidewall of the accommodating portion 111, as well as the bottom wall of the filter element 15 and the bottom wall of the accommodating portion 111, spaced apart.

[0169] In some embodiments, the filter element 15 further includes at least one second lifting portion 156 , which is protruding from the bottom surface of the filter portion 151 and extends toward the opening of the accommodating portion 111. For example, the second lifting portion 156 may be cylindrical. The second lifting portion 156 may extend upward from the inner bottom surface of the filter holder 152 . The second lifting portion 156 facilitates gripping by the user, allowing for easy removal of the filter element 15 from the accommodating portion 111 .

[0170] In some embodiments, the second lifting portion 156 includes a first sub-lifting portion 1560 and a second sub-lifting portion 1561. The second sub-lifting portion 1561 is disposed at the top of the first sub-lifting portion 1560 and protrudes radially from the first sub-lifting portion 1560. Specifically, the second sub-lifting portion 1561 protrudes from the outer circumference of the first sub-lifting portion 1560. When a user grasps the second lifting portion 156, the second sub-lifting portion 1561 facilitates the user's application of force, thereby easily removing the filter element 15 from the accommodating portion 111. For example, the second sub-lifting portion 1561 is a latch.

[0171] In some embodiments, the at least one second sub-lifting portion 1561 includes multiple second sub-lifting portions 1561, and the multiple second sub-lifting portions 1561 are arranged circumferentially around the top of the first sub-lifting portion 1560 to facilitate the user to hold the second lifting portion 156 from various angles to apply force.

[0172] Referring to Figure 25B , in some embodiments, the end cap 14 includes an end cap body 140, which includes at least one water inlet channel 30. The inlet end of the water inlet channel 30 is connected to the water inlet 121, and thus to the wastewater to be filtered. The outlet end of the water inlet channel 30 is connected to the filter 151, allowing the water to be filtered introduced by the water inlet 121 to pass through the water inlet channel 30 and enter the filter 151 for filtration.

[0173] Referring to Figures 26 to 30 , in some embodiments, the end cap 14 further includes a fourth sealing portion 31 and a fourth sealing member 311. For example, the fourth sealing portion 31 is annular and arranged around the outer peripheral wall of the end cap body 140. The fourth sealing member 311 is disposed within the fourth sealing portion 31. For example, the fourth sealing member 311 is annular and is sealed within the fourth sealing portion 31. The fourth sealing portion may be a fourth sealing groove.

[0174] When the end cover 14 is installed at the top opening of the accommodating portion 111, the fourth sealing member 311 can be clamped between the groove wall of the fourth sealing portion 31 and the peripheral side wall of the accommodating portion 111, thereby sealing the gap between the outer peripheral wall of the end cover 14 and the peripheral side wall of the accommodating portion 111, thereby sealing the top opening of the accommodating portion 111.

[0175] In some embodiments, the end cap 14 further includes a fifth sealing portion 32 and a fifth sealing member 321. The fifth sealing portion 32 is disposed on the outer peripheral wall of the end cap 14. For example, the fifth sealing portion 32 is annular and arranged around the outer peripheral wall of the end cap 14. The fifth sealing member 321 is disposed within the fifth sealing portion 32. For example, the fifth sealing member 321 is annular and is sealed within the fifth sealing portion 32. The fifth sealing portion may be a fifth sealing groove.

[0176] When the end cover 14 is installed at the top opening of the accommodating portion 111, the fifth sealing member 321 can be clamped between the groove wall of the fifth sealing member 32 and the peripheral side wall of the accommodating portion 111, and then cooperate with the fourth sealing member 311 to seal the gap between the outer peripheral wall of the end cover 14 and the peripheral side wall of the accommodating portion 111.

[0177] In some embodiments, the fifth sealing portion 32 is spaced apart from the upper side of the fourth sealing portion 31, and the inlet end of the water inlet channel 30 is located in the spaced area between the fourth sealing portion 31 and the fifth sealing portion 32. When the end cap 14 is installed at the top opening of the accommodating portion 111, the inner end of the water inlet portion 121 is connected to the inlet end of the water inlet channel 30, and the filtered water introduced by the water inlet portion 121 can be sealed in the spaced area between the fourth sealing portion 31 and the fifth sealing portion 32, thereby preventing the filtered water from entering the accommodating portion 111 or overflowing from the upper side of the end cap 14 out of the housing 11.

[0178] Referring to Figure 32 , in some embodiments, the end cap 14 further includes a second water diversion portion 33, which is formed in the spaced region between the fourth sealing portion 31 and the fifth sealing portion 32. For example, the second water diversion portion 33 is arranged around the outer peripheral wall of the end cap 14, and the inlet end of the water inlet channel 30 communicates with the second water diversion portion 33. Referring to Figure 26 , when the end cap 14 is installed at the top opening of the accommodating portion 111, the fourth sealing member 311 and the fifth sealing member 321 respectively abut against the peripheral sidewalls of the accommodating portion 111 to seal the second water diversion portion 33.

[0179] In some embodiments, the inner end of the water inlet portion 121 communicates with the second water guide portion 33, and further communicates with the inlet end of the water inlet channel 30 through the second water guide portion 33. In this way, when installing the end cap 14, it is not necessary to arrange the inlet end of the water inlet channel 30 and the inner end of the water inlet portion 121 directly opposite each other. Instead, the inlet end of the water inlet channel 30 and the water inlet portion 121 are connected through the second water guide portion 33, thereby improving the convenience of installing the end cap 14.

[0180] In some embodiments, the at least one water inlet channel 30 includes multiple water inlet channels 30, the inlet ends of the multiple water inlet channels 30 being arranged at intervals on the peripheral sidewall of the end cover 14 and each communicating with the second water diversion portion 33. The outlet ends of the multiple water inlet channels 30 are all provided on the bottom surface of the end cover 14 and communicating with the filter portion 151. In this way, water introduced into the second water diversion portion 33 by the water inlet portion 121 can be introduced into the filter portion 151 through the multiple water inlet channels 30, thereby improving water intake efficiency.

[0181] 26 and 32 , the end cap 14 further includes a first through hole 34, which is provided in the end cap body 140 and is arranged to penetrate the end cap body 140 along the height direction of the end cap 14. The filter device 10 further includes a warning assembly 4, which is installed at the first through hole 34. The warning assembly 4 includes a warning column 41 and a first spring 42. The warning column 41 is movably provided at the first through hole 34, and the warning column 41 can move up and down along the extension direction of the first through hole 34. The first spring 42 is connected to the warning column 41 and is configured to drive the warning column 41 to move downward along the first through hole 34, thereby enabling the lower end of the first warning column 282 to block the bottom port of the first through hole 34.

[0182] When the filter portion 151 in the filter element 15 is clogged, the water inlet 121 will still guide the sewage into the filter portion 151 through the water inlet channel 30, causing the water level in the filter portion 151 to rise and submerge the lower end of the first through hole 34. At this time, the water pressure at the bottom end of the first through hole 34 increases.

[0183] When the water pressure at the bottom port of the first through hole 34 increases to greater than the preset water pressure, the warning column 41 can overcome the elastic force of the first spring 42 and move upward under the action of the water pressure, and then protrude from the top of the end cover 14 to remind the user to replace the filter element 15 or clean the filter part 151 in time, thereby restoring the filtering function of the filter device 10.

[0184] Referring to Figure 26, in some embodiments, the end cap 14 further includes an overflow port 35, which is disposed on the outer wall of the end cap 14. The inner end of the overflow port 35 communicates with the first through-hole 34, and the outer end of the overflow port 35 communicates with the accommodating portion 111 outside the end cap 14. The overflow port 35 is disposed near the bottom end of the first through-hole 34. For example, the overflow port 35 is disposed below the fourth sealing member 311, and the outer end of the overflow port 35 is spaced apart from the peripheral sidewall of the accommodating portion 111, so that the overflow port 35 can communicate with the peripheral area of ​​the accommodating portion 111.

[0185] It is understood that when the lower end of the warning post 41 blocks the bottom end of the first through hole 34, the warning post 41 can also block the overflow port 35. If the filter portion 151 in the filter element 15 becomes clogged, the warning post 41 can move upward along the first through hole 34 under the action of water pressure, thereby opening the bottom end of the first through hole 34.

[0186] At this time, the overflow port 35 is also opened, so that the sewage in the filter part 151 can be introduced into the accommodating part 111 in the external area of ​​the filter element 15 through the bottom port of the first through hole 34 and the overflow port 35 in sequence, and then discharged to the outside of the shell 11 through the bottom area of ​​the accommodating part 111.

[0187] In this way, the smooth flow of water in the water inlet 121 and the water inlet channel 30 in the filter device 10 is effectively guaranteed, thereby ensuring that the clothing processing equipment 1000 connected to the water inlet 121 can drain water smoothly, preventing the drainage pipe of the clothing processing equipment 1000 from being blocked.

[0188] It should be noted that the overflow port 35 cooperates with the first through hole 34 and the warning component 4, so that when the filter device 10 is blocked, it can not only promptly remind the user to replace or clean the filter element 15 through the warning column 41, but also maintain the drainage function of the filter device 10 by opening the overflow port 35, thereby ensuring that the clothing processing equipment 1000 can drain water smoothly.

[0189] 25A to 26 , in some embodiments, the end cap 14 further includes a third support member 36 and a first water guide 360. The third support member 36 is protruding from the bottom of the end cap 14. For example, the third support member 36 is annular. The first water guide 360 ​​is formed within the third support member 36 and opens toward the filter portion 151.

[0190] The first water guide 360 ​​is in communication with the filter 151 along the height direction of the housing 11. The outlet end of the water inlet passage 30 is in communication with the first water guide 360, so that water in the water inlet 121 can be directed into the first water guide 360 ​​through the water inlet passage 30, and then into the filter 151 through the first water guide 360 ​​for filtration.

[0191] In some embodiments, the bottom end of the first through hole 34 is located at the top of the first water guide 360, that is, the bottom end of the first through hole 34 is connected to the first water guide 360. In the event that the filter element 15 becomes clogged, the water level in the filter portion 151 rises and does not exceed the first water guide 360, thereby increasing the water pressure at the bottom end of the first through hole 34.

[0192] When the water pressure at the bottom end of the first through hole 34 exceeds the preset water pressure, the warning post 41 moves upward under the action of the water pressure to open the bottom end of the first through hole 34 and the overflow port 35. At this time, the water in the first water guide 360 ​​can be introduced into the accommodating portion 111 outside the filter element 15 through the bottom end of the first through hole 34 and the overflow port 35, and then discharged to the outside of the housing 11 through the accommodating portion 111.

[0193] Referring to Figures 25A to 26, in some embodiments, the bottom end of the third support member 36 is supported on the top of the peripheral side wall of the filter element 15, so that the third support member 36 can be arranged around the peripheral side of the filter portion 151, and the first water guide portion 360 is directly connected to the filter portion 151 along the height direction of the shell 11.

[0194] In some embodiments, a second overflow cavity 101 is formed between the outer wall of the third support member 36 , the peripheral side wall of the accommodating portion 111 , the fourth sealing member 311 and the first support member 157 , and the outer end of the overflow port 35 is connected to the second overflow cavity 101 .

[0195] A second through hole 1571 is defined in the first support member 157, extending through the first support member 157 along the height of the filter element 15. The second through hole 1571 connects the second overflow chamber 101 above the first support member 157 with the accommodating portion 111 below the first support member 157. Thus, if a blockage occurs within the filter portion 151, water within the filter portion 151 and the first water guide portion 360 can flow out through the bottom port and overflow port 35 of the first through hole 34 and into the second overflow chamber 101. Water within the second overflow chamber 101 can then be directed through the second through hole 1571 into the accommodating portion 111 below the first support member 157, and then discharged from the housing 11.

[0196] In some embodiments, the filter element 15 further includes a second filter screen 1572 . The second filter screen 1572 is disposed at the second through hole 1571 of the first support element 157 to filter the water to be filtered in the second overflow chamber 101 .

[0197] In some embodiments, referring to Figures 26 and 32, the outer peripheral wall of the bottom end of the third support member 36 is provided with a fifth engaging portion 361, with the opening facing downward. For example, the fifth engaging portion 361 is a stepped groove. When the bottom end of the third support member 36 is supported on the filter element 15, the top wall of the groove of the fifth engaging portion 361 abuts against the top surface of the inner edge of the first support member 157, and the side walls of the groove of the fifth engaging portion 361 abut against the inner wall of the filter portion 151, thereby maintaining the first water guide portion 360 and the filter portion 151 in direct communication along the height direction of the housing 11, and isolating the first water guide portion 360 and the filter portion 151 from the second overflow chamber 101 outside the filter element 15.

[0198] 33 and 34 , in some embodiments, the warning assembly 4 further includes a telescopic member 43. The telescopic member 43 extends in the height direction of the warning assembly 4 (the vertical direction as shown in FIG. 34 ) and is telescopically disposed within the first through hole 34 . A warning post 41 is disposed within the telescopic member 43 , with the lower end of the warning post 41 connected to the bottom end of the telescopic member 43 . A first spring 42 is disposed within the telescopic member 43 and sleeved onto the warning post 41 .

[0199] The bottom end of the first spring 42 abuts against the bottom ends of the warning post 41 and the telescopic member 43. The first spring 42 can drive the bottom ends of the telescopic member 43 and the bottom ends of the warning post 41 downward, thereby causing the outer peripheral wall of the bottom end of the telescopic member 43 to block the bottom end of the first through hole 34 and the overflow port 35. In the event of a blockage in the filter portion 151, the water pressure at the bottom end of the first through hole 34 causes the bottom end of the telescopic member 43 to move upward, thereby opening the bottom end of the first through hole 34 and the overflow port 35, allowing water in the filter portion 151 to be discharged through the overflow port 35.

[0200] In some embodiments, the upper portion of the telescopic member 43 is a bellows, and through the bellows structure, the telescopic member 43 can be telescopically disposed in the first through hole 34. The outer peripheral wall of the lower end of the telescopic member 43 is a smooth structure, so that the outer peripheral wall of the lower end of the telescopic member 43 can block the bottom end and overflow port 35 of the first through hole 34.

[0201] 33 and 34 , in some embodiments, the warning assembly 4 further includes a first cover 44, which is provided to cover the top end of the first through hole 34. The first cover 44 is provided with a third through hole arranged opposite to the top end of the warning column 41. The top end of the warning column 41 movably passes through the third through hole of the first cover 44, and then protrudes out of the top surface of the first cover 44. The top of the telescopic member 43 is connected to the bottom surface of the first cover 44, so when the telescopic member 43 is extended or retracted, the bottom end of the telescopic member 43 can move up and down along the first through hole 34. The top of the first spring 42 is against the bottom surface of the first cover 44, so that the bottom end of the first spring 42 can drive the bottom end of the telescopic member 43 and the warning column 41 to move downward along the first through hole 34, thereby blocking the bottom end and the overflow port 35 of the first through hole 34.

[0202] In some embodiments, the end cap 14 further includes a mounting portion 341 disposed within the end cap body 140 and extending toward the top of the end cap body 140. A first through hole 34 is formed within the mounting portion 341. The first cover 44 is sleeved over the top end of the mounting portion 341, thereby allowing the warning assembly 4 to be mounted in the first through hole 34.

[0203] 35 and 36 , in some embodiments, the end cap 14 further includes a second cover body 5, which is detachably mounted on the top surface of the end cap body 140. This makes it easier for the user to install the warning component 4. The second cover body 5 is provided with a through-hole 51, which is arranged opposite to the warning column 41. After the top end of the warning column 41 passes through the first through-hole 34, it can be inserted into the through-hole 51. For example, when the filter portion 151 is not clogged, the top surface of the warning column 41 is flush with the top surface of the second cover body 5, thereby facilitating a reminder for the user to replace the filter element 15 or clean the filter portion 151 in a timely manner.

[0204] 30 and 36 , the second cover 5 includes a second cover body 50 and a snap-fit ​​portion 52, which is disposed at the bottom of the second cover body 50. A snap-fit ​​opening 38 is disposed on the peripheral sidewall of the top of the end cover body 140, and the second cover 5 is snap-fitted to the snap-fit ​​opening 38 via the snap-fit ​​portion 52, thereby allowing the second cover 5 to detachably cover the top of the end cover 14.

[0205] It should be noted that, in some embodiments, the second cover 5 may also be integrally formed in the top area of ​​the end cover 14 .

[0206] Referring to Figures 37 to 39 , in some embodiments, the end cap 14 further includes at least one latch 6 movably disposed between the second cover 5 and the top of the end cap body 140. Referring to Figures 31 and 32 , the end cap 14 further includes at least one telescopic opening 39 disposed on the outer peripheral wall of the end cap body 140. The housing 11 further includes at least one stopper 117 recessed into the peripheral sidewall of the accommodating portion 111 at the notch, and arranged opposite the telescopic opening 39.

[0207] 37 to 39 , in some embodiments, the latch 6 includes a latch body 60. The first end of the latch body 60 can pass through the telescopic opening 39 and engage within the limiting portion 117, thereby locking the end cap 14 in the notch of the accommodating portion 111. The second end of the latch body 60 can pass through and be exposed outside the second cover 5, thereby facilitating a user's pressing.

[0208] The pressing portion 61 presses the end of the lock 6 exposed outside the second cover body 5, so that the first end of the lock body 60 can move toward the inside of the telescopic opening 39, that is, move in the direction away from the limiting portion 117, so that the first end of the lock body 60 is separated from the limiting portion 117, and the end cover 14 can be removed from the slot of the accommodating portion 111.

[0209] In some embodiments, the lock buckle 6 further includes a pressing portion 61, which is disposed in the second section of the lock buckle body 60 and extends in a curved manner toward the first end of the lock buckle body 60. The pressing portion 61 is exposed to the second cover 5. By pressing the pressing portion 61 away from the first end, the lock buckle 6 can be separated from the limiting portion 117 and the first end of the lock buckle 6 can be retracted into the telescopic opening 39.

[0210] 47 and 48 , the end cap 14 further includes a second spring 7 . The second spring 7 is disposed within the end cap 14 and abuts against the second section of the latch 6 to automatically move the latch 6 toward the first end, thereby extending the first end of the latch 6 out of the telescopic opening 39 and engaging with the stopper 117 .

[0211] In some embodiments, referring to Figure 38 , the at least one locking catch 6 includes two locking catches 6 , which are horizontally positioned opposite each other within the end cap 14 . Accordingly, referring to Figures 31 and 32 , a telescopic opening 39 is defined on opposite sides of the end cap body 140 . Referring to Figure 39 , two stoppers 117 are defined on the sidewalls surrounding the notch of the accommodating portion 111 , corresponding to the two telescopic openings 39 .

[0212] The second spring 7 is disposed between the two lock catches 6. One end of the second spring 7 abuts against the second section of one lock catch 6, while the other end of the second spring 7 abuts against the second section of the other lock catch 6, thereby driving the first ends of the two lock catches 6 to automatically extend out of the corresponding telescopic openings 39 and engage with the corresponding limiting portions 117.

[0213] In some embodiments, the lock catch 6 further includes a positioning portion 62 protruding from the second section of the lock catch body 60. When two lock catches 6 are provided, one end of the second spring 7 is sleeved on the positioning portion 62 of one lock catch 6, and the other end of the second spring 7 is sleeved on the positioning portion 62 of the other lock catch 6, thereby stably fixing the second spring 7 between the two lock catches 6.

[0214] In some embodiments, referring to FIG. 37 , the lock buckle 6 further includes at least one stopper 63 , for example, two stoppers 63 . The two stoppers 63 are respectively provided on the left and right sides of the first end of the lock buckle body 60 . When the lock buckle 6 extends out of the telescopic opening 39 under the elastic force of the second spring 7 and engages with the stopper 117 , the stoppers 63 can abut against the inner walls of the telescopic opening 39 on both sides, thereby preventing the lock buckle 6 from falling out of the telescopic opening 39 .

[0215] In some embodiments, referring to Figure 35, the second cover body 5 also includes a first lifting portion 53 and two pressing ports 54. The first lifting portion 53 is provided on the top surface of the second cover body 50 and extends in the horizontal direction.
