[0074] Figure 7 yes Figure 2 A top view of the structure shown, Figure 8 yes Figure 7 A cross-sectional view of the structure shown along section line BB, Fig. 9 yes Figure 8 The schematic diagram of the cross-sectional structure shown in FIG. 1 is a schematic diagram of the structure under another viewing angle. Fig.10 yes Figure 7 The schematic diagram of the structure of the end cover 14, Fig.11 yes Fig.10 The end cap 14 is shown in cross-section along section line CC.

[0075] Combination Figure 7-Figure 11 The filter device 10 includes an end cap 14, which is disposed at the opening of the receiving groove 111. The end cap 14 can be fixed at the opening of the receiving groove 111 in a detachable manner, and part of the end cap 14 is located in the receiving groove 111, and the rest of the end cap 14 is exposed to the receiving groove 111, and the user can remove the end cap 14 through the part exposed to the receiving groove 111. For example, a lifting portion 141 is provided at the top of the end cap 14, and the user can remove the end cap 14 from the receiving groove 111 through the lifting portion 141.

[0076] When the end cap 14 is disposed at the opening of the receiving groove 111, the end cap 14 will cover the top opening of the receiving groove 111 to seal the receiving groove 111. The shape of the end cap 14 can match the shape of the opening of the receiving groove 111. As shown in the figure, when the shape of the opening of the receiving groove 111 is circular, the end cap 14 can be a circular end cap 14.

[0077] Specifically, the end cap 14 is provided with a water inlet 142, and the water inlet 142 is used for the water to be filtered to enter the end cap 14. It should be understood that the end cap 14 includes a top wall of the end cap 14 and a side wall of the end cap 14, and the side wall of the end cap 14 is arranged around the top wall of the end cap 14, so that the top wall of the end cap 14 and the side wall of the end cap 14 are jointly enclosed to form a water guide groove 143 with an opening downward. The water inlet 142 can be arranged on the top wall of the end cap 14 of the end cap 14, or on the side wall of the end cap 14, or on the top wall of the end cap 14 and the side wall of the end cap 14 at the same time. At this time, the water to be filtered enters the end cap 14 through the water inlet 142, and can enter the water guide groove 21 through the water inlet 142. The number of the water inlets 142 can be set to multiple, and the multiple water inlets 142 can be arranged at intervals along the circumference of the end cap 14, that is, arranged at intervals along the circumference of the side wall of the end cap 14.

[0078] Fig.12 is a schematic diagram of the structure provided at the receiving groove 111. Fig.13 yes Fig.12 Structural explosion diagram of the structure shown, Fig.14 yes Fig.12 A cross-sectional view of the structure shown.

[0079] Combination Figure 8 , Fig. 9 as well as Figure 12-14 The filter device 10 includes a filter element 15, which is disposed in the receiving groove 111 and below the end cover 14. The filter element 15 is formed with a filter groove 151. The filter element 15 can be located in the receiving groove 111 as a whole, such as Figure 8 as well as Fig. 9 As shown. The filter element 15 and the end cap 14 can be directly contacted with each other or connected by other structures. The opening formed by the filter element 15 is upward and toward the end cap 14, so that the water in the end cap 14 can be naturally introduced into the filter tank 151 by gravity. In combination with the above content, that is, the opening of the filter tank 151 is toward the opening at the lower part of the water guide groove 143, and the water in the water guide groove 143 is introduced into the filter tank 151 through its lower opening.

[0080] After the water in the end cover 14 can be introduced into the filter tank 151, the water in the filter tank 151 will further pass through the filter tank 151 to achieve filtration, and the water that passes through the filter tank 151 is introduced into the receiving tank 111 and discharged from the receiving tank 111. In combination with the above content, the water in the receiving tank 111 is discharged through the water outlet pipe 122. Among them, the filter element 15 can be specifically arranged in a cylindrical shape, and the receiving tank 111 can also be arranged in a cylindrical shape, for example Figure 8 as well as Fig. 9The outer wall of the filter element 15 and the inner wall of the accommodating groove 111 are spaced apart to form a gap, so as to ensure that the water discharged from the filter groove 151 can flow down from the gap without the inner wall of the accommodating groove 111 hindering the flow of the water discharged from the filter groove 151 .

[0081] Combination Fig.12 In some specific embodiments, the filter element 15 may include a filter frame 152 and a filter net 153. The filter frame 152 forms a plurality of hollow areas, and the filter net 153 is disposed at the hollow areas. The filter frame 152 constitutes the skeleton of the filter element 15, and the filter net 153 is a structure for the filter element 15 to perform filtering functions. The filter frame 152 and the filter net 153 constitute a filter tank 151, and the water in the filter tank 151 is discharged through the filter net 153 to achieve filtering.

[0082] It should be understood that since synthetic clothes contain microplastics such as polyester fibers and acrylic fibers, most of them are non-biodegradable plastics. Washing machine drainage contains a lot of "microplastics", "microplastics" refers to plastic fragments and particles with a diameter of less than 5 mm. In some application scenarios, the aperture of the filter 153 is smaller than the preset aperture, so that the filter 153 can have a good filtering effect on the "microfibers".

[0083] Fig.15 yes Fig.13 The structural diagram of the cleaning part 16, Fig.16 yes Fig.15 The cleaning element 16 is shown in cross-section along the section line DD.

[0084] Combination Fig.13 as well as Fig.14 The filter device 10 includes a cleaning member 16, which is disposed at the bottom of the end cover 14. The top of the cleaning member 16 can be disposed in the end cover 14, that is, the top is disposed in the water guide groove 143. At this time, the outer peripheral wall of the top of the cleaning member 16 can be attached to the inner peripheral wall of the water guide groove 143, so that all the water in the water guide groove 143 can be introduced into the cleaning member 16.

[0085] Combination Fig.15 as well as Fig.16 The bottom of the cleaning member 16 is provided with a water guide hole 161, and the depth direction of the water guide hole 161 is inclined relative to the vertical direction toward the inner wall of the filter tank 151, that is, the depth direction of the water guide hole 161 is inclined toward the direction away from the center of the water guide member. When the filter device 10 is placed normally, the height direction of the cleaning member 16 is the vertical direction. Fig.16, there is an angle A between the depth direction of the water guide hole 161 and the vertical direction. When the number of the water guide holes 161 is set to be multiple, the angles between the multiple water guide holes 161 and the vertical direction can be the same or different. The multiple water guide holes 161 shown in the drawings have the same angle in the vertical direction.

[0086] Through the above-mentioned arrangement, the water guide hole 161 can guide the water introduced into the cleaning member 16 by the end cover 14 to the inner wall of the filter tank 151, so as to flush the inner wall of the filter tank 151 through the impact of the water flow. Therefore, based on the filter device 10 provided by the above-mentioned embodiment of the present application, in the process of introducing the water to be filtered from the cleaning member 16 to the filter tank 151, due to the arrangement of the water guide hole 161, the water to be filtered will directly flush the inner wall of the filter tank 151, which can prevent the filter element 15 from being blocked by debris, thereby ensuring a good filtering effect.

[0087] Continue to combine Fig.16 In some specific embodiments, the cleaning member 16 includes a cleaning bottom wall 162 and a cleaning side wall 163, and the cleaning bottom wall 162 is arranged around the cleaning side wall 163 to form a cleaning groove 164. The cleaning bottom wall 162 can be arranged in a circular shape, and the cleaning side wall 163 is arranged in a circular ring shape. The water guide hole 161 is arranged on the cleaning bottom wall 162, and the water in the end cover 14 is introduced into the cleaning groove 164 to be discharged from the water guide hole 161.

[0088] Combined with the arrangement of the water guide groove 143 in the above embodiment and Fig.14 When the cleaning side wall 163 of the cleaning member 16 is in contact with the inner wall of the water guide groove 143, the water guide groove 143 and the cleaning groove 164 together form a water guide cavity 17. The water inlet 142 is located above the cleaning member 16, and the water inlet 142 guides water into the water guide cavity 17 to be discharged from the water guide hole 161. That is, the water introduced into the water guide cavity 17 through the water inlet 142 will be discharged from the water guide hole 161, and enter the filter tank 151 from the water guide hole 161, thereby ensuring a good filtering effect.

[0089] In some specific embodiments, the water guide holes 161 are divided into at least two groups, each group of water guide holes 161 includes a plurality of water guide holes 161, and the water guide holes 161 in each group are arranged at intervals from each other. Fig.15 as well as Fig.16 The water guide holes 161 are divided into two groups, each group of water guide holes 161 includes four water guide holes 161, and the four water guide holes 161 are arranged at intervals from each other.

[0090] Specifically, the plurality of water guide holes 161 in each group can be arranged in a ring shape, which can be a closed shape, such as a circle, an ellipse, a rectangle, etc. In combination with the embodiment in which the cleaning bottom wall 162 is arranged in a circle, the plurality of water guide holes 161 in each group can be arranged in a circle, and each water guide hole 161 is arranged in an arc shape.

[0091] The two groups of water guide holes 161 can be arranged in a ring at intervals, and the depth direction of the water guide holes 161 is tilted relative to the vertical direction toward the outside of the ring. When the two groups of water guide holes 161 are arranged in a circular shape, the two circles can be concentrically arranged with different radii, and the depth direction of the water guide holes 161 is tilted in the direction away from the center of the circle.

[0092] It should be understood that by providing multiple groups of water guide holes 161, the water in the cleaning tank 164 can be introduced into the filter tank 151 more quickly, thereby avoiding the problem of poor water guide in the filter tank 151. By arranging each group 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 comprehensive flushing of the inner wall of the filter tank 151.

[0093] Combination Figure 8 , Fig. 9 as well as Fig.13 , Fig.14 In some specific embodiments, the filter device 10 includes an elastic member 18, which connects the end cover 14 and the filter element 15, and the elastic member 18 can be elastically deformed in the vertical direction and / or the horizontal direction.

[0094] Specifically, the elastic member 18 may be a structure that can be elastically deformed, such as a spring or a spring sheet. In the accompanying drawings, the elastic member 18 is shown as a spring. The top end of the elastic member 18 may be connected to the bottom end of the end cover 14, and the bottom end of the elastic member 18 may be connected to the filter element 15. The end cover 14 and the filter element 15 may be connected only through the elastic member 18, thereby achieving the filter element 15 being fixed to the end cover 14 through the elastic member 18. Of course, in other embodiments, other structures may be provided between the end cover 14 and the elastic member 18, and the other structures may also connect the end cover 14 and the filter element 15.

[0095] It should be understood that when the water in the end cover 14 is introduced into the filter tank 151, the gravity of the water will impact the filter tank 151, thereby causing the filter element 15 to drive the elastic element 18 to undergo elastic deformation, so that the filter element 15 shakes. Specifically, the elastic element 18 may undergo elastic deformation only in the vertical direction, causing the filter element 15 to shake in the vertical direction, the elastic element 18 may undergo elastic deformation only in the horizontal direction, causing the filter element 15 to shake in the horizontal direction, or the elastic element 18 may undergo elastic deformation in both the vertical and horizontal directions, causing the filter element 15 to shake in both the vertical and horizontal directions.

[0096] In combination with the above, through the setting of the elastic member 18, when the water in the end cover 14 is introduced into the filter element 15, due to the gravity of the water itself, the filter element 15 drives the elastic member 18 to undergo elastic deformation, thereby causing the filter element 15 to vibrate. Through the vibration of the filter element 15, the filter element 15 can shake off the debris on the inner wall of the filter slot 151, thereby preventing the debris from accumulating too much and clogging the filter slot 151, thereby affecting the effect of the filter element 15 and the water guiding effect.

[0097] It should be understood that in the embodiment with the elastic member 18, the cleaning member 16 can be omitted, that is, the water in the end cover 14 is directly introduced into the filter 15, and a relatively good filtering effect can be achieved through the shaking of the filter 15. Of course, in the embodiment with the elastic member 18, the cleaning member 16 can also be provided, and in this case, the double anti-blocking effect can be achieved through the shaking of the filter 15 and the flushing of the water flow led out of the cleaning member 16, and a better filtering effect can be achieved.

[0098] Combination Fig.16 In the embodiment in which the cleaning member 16 is provided, the top of the elastic member 18 is connected to the bottom wall of the cleaning member 16, the bottom of the elastic member 18 is connected to the bottom wall of the filter tank 151, and at least part of the elastic member 18 is located in the filter tank 151. By connecting the bottom end of the elastic member 18 to the bottom wall of the filter tank 151, the elastic member 18 is at least partially located in the filter tank 151, so that the elastic member 18 can have a stable bearing effect on the filter 15, thereby making the position of the filter 15 relatively stable. Among them, the top of the elastic member 18 can be fixed to the center position of the cleaning member 16, and at this time, the length direction of the elastic member 18 is the vertical direction.

[0100] Combination Fig.16In some specific embodiments, the center of the bottom wall of the cleaning member 16 protrudes downward to form a first connecting column 165, and the water guide hole 161 is arranged on the peripheral side of the first connecting column 165. Fig.16 As for the arrangement of the cleaning bottom wall 162 and the cleaning side wall 163 of the cleaning member 16 , in some specific embodiments, the cleaning bottom wall 162 of the cleaning member 16 protrudes downward to form a first connecting column 165 .

[0101] Combination Fig.17 The center of the bottom wall of the filter tank 151 protrudes upward to form a second connecting column 154, and the height of the second connecting column 154 is lower than the depth of the filter tank 151. The bottom end of the first connecting column 165 can be located above the filter element 15, and the bottom end of the first connecting column 165 can also be located in the filter tank 151.

[0102] The elastic member 18 is arranged in a spring shape, the top end of the elastic member 18 is sleeved on the first connecting column 165, and the bottom end of the elastic member 18 is sleeved on the second connecting column 154 to achieve the connection between the cleaning member 16 and the filter member 15. Through the arrangement of the first connecting column 165 and the second connecting column 154, the elastic member 18 can well connect the cleaning member 16 and the filter member 15.

[0103] Combination Fig.13 as well as Fig.14 In the embodiment in which the elastic member 18 is provided, the filter device 10 may further include a telescopic cylinder 19, the top end of which is sleeved on the end cover 14, and the bottom end of which is sleeved on the filter element 15. The outer wall of the top of the telescopic cylinder 19 may be connected to the inner wall of the bottom of the end cover 14, and the bottom of the telescopic cylinder 19 may be sleeved on the outer wall of the top of the filter element 15. In order to ensure a better connection effect between the telescopic cylinder 19 and the filter element 15, the telescopic cylinder 19 may be clamped on the filter element 15 by an annular pipe clamp (not shown). Through this arrangement, the water in the end cover 14 will be introduced into the filter element 15 through the telescopic cylinder 19, and at this time, the filter element 15 and the end cover 14 are indirectly connected through the telescopic cylinder 19. Combined with the arrangement of the elastic member 18, the elastic member 18 is located in the telescopic cylinder 19 and the filter tank 151.

[0104] Specifically, the telescopic cylinder 19 is flexibly configured to be able to expand and contract in the height direction. Combined with the configuration of the elastic member 18, when the water in the end cover 14 flows into the filter tank 151 through the telescopic cylinder 19, the elastic member 18 undergoes elastic deformation in the vertical direction, and at this time, the telescopic cylinder 19 expands and contracts to cause the filter element 15 to vibrate. Of course, in other embodiments, the telescopic cylinder 19 may also be deformed in the horizontal direction, and then cooperate with the elastic member 18 to undergo elastic deformation in the horizontal direction, so that the filter element 15 can vibrate in the horizontal direction.

[0106] Combination Fig.11 as well as Fig.18 In some specific embodiments, a water diversion groove 21 is formed on the side wall of the end cover 14, and the water diversion groove 21 is connected to the water guide groove 143 through the water inlet 142. The water diversion groove 21 can be arranged in an annular shape, and the water inlet 142 can be arranged in a plurality, and the plurality of water inlets 142 are all connected to the water diversion groove 21.

[0107] Combination Figure 8 When the end cover 14 is disposed in the receiving groove 111, the opening of the water diversion groove 21 is attached to the side wall of the receiving groove 111 to seal the water diversion groove 21. The side wall of the receiving groove 111 is provided with a water diversion hole 22 connected to the water diversion groove 21. The water diversion hole 22 is used to introduce external water into the water diversion groove 21 to be introduced into the water inlet 142. At this time, the external water is introduced into the water diversion groove 21 through the water diversion hole 22, and the water in the water diversion groove 21 is further introduced into the water guide groove 143 through the water inlet 142.

[0108] It should be understood that in the embodiment without the water diversion groove 21, the external water is introduced into the end cover 14 through the water inlet hole, and the internal space of the end cover 14 is the water diversion groove 143. In the embodiment with the water diversion groove 21, the water diversion groove 21 and the water diversion groove 143 are both part of the internal space of the end cover 14, and the external water is introduced into the end cover 14 through the water diversion hole 22.

[0109] Combination Fig.18 In some specific embodiments, the outer wall of the end cover 14 is protruded to form a first annular portion 144 and a second annular portion 145, and the outer wall of the end cover 14 is provided with a water inlet 142 and is located between the first annular portion 144 and the second annular portion 145. The protrusion heights of the first annular portion 144 and the second annular portion 145 relative to the outer wall of the end cover 14 are the same. The first annular portion 144 and the second annular portion 145 extend along the circumference of the end cover 14, and the first annular portion 144 and the second annular portion 145 are spaced apart in the height direction of the end cover 14 to form the water diversion groove 21. In combination with the above content, when the end cover 14 is set in the receiving groove 111, the outer sides of the first annular portion 144 and the second annular portion 145 are used to abut against the inner wall of the receiving groove 111, thereby sealing the opening at the end of the water diversion groove 21.

[0110] Further, the filter device 10 includes a first sealing ring 231 and a second sealing ring 232. The first sealing ring 231 is disposed between the inner wall of the filter tank 151 and the first annular portion 144, and the second sealing ring 232 is disposed between the inner wall of the filter tank 151 and the second annular portion 145. The first sealing ring 231 and the second sealing ring 232 are flexibly disposed. The first sealing ring 231 is used to seal the gap between the filter tank 151 and the first annular portion 144, and the second sealing ring 232 is used to seal the gap between the filter tank 151 and the second annular portion 145. It should be understood that when the first annular portion 144 and the second annular portion 145 contact the inner wall of the receiving tank 111, since the materials of the first annular portion 144 and the second annular portion 145 are relatively hard, there will be a certain gap between them and the inner wall of the receiving tank 111. Since the first sealing ring 231 and the second sealing ring 232 are flexibly arranged, when the first sealing ring 231 and the second sealing ring 232 contact the inner wall of the receiving groove 111 , the gap between the first annular portion 144 and the second annular portion 145 and the inner wall of the receiving groove 111 can be sealed.

[0111] Among them, the outer side of the first annular portion 144 can be provided with a first annular groove 146, and the outer side of the second annular portion 145 can be provided with a second annular groove 147. The first sealing ring 231 can be arranged in the first annular groove 146, and the second annular portion 145 can be arranged in the second annular groove 147. The first sealing ring 231 protrudes relative to the opening of the first annular groove 146, and the second sealing ring 232 protrudes relative to the opening of the second annular groove 147, so that the first sealing ring 231 contacts the inner wall of the accommodating groove 111, and the second sealing ring 232 contacts the inner wall of the accommodating groove 111.

[0113] In some specific embodiments, the filter device 10 includes the housing 11, the end cap 14 and the filter element 15 in the above embodiment. The specific configuration of the housing 11, the end cap 14 and the filter element 15 can refer to the above embodiment and will not be repeated. In this embodiment, the filter device 10 also includes a cleaning brush 24, at least part of which is disposed in the filter tank 151. Fig.21 , the cleaning brush 24 can be completely located in the accommodating groove 111.

[0114] Specifically, the cleaning brush 24 contacts the inner wall of the filter tank 151, and the portion of the cleaning brush 24 contacting the inner wall of the filter tank 151 is flexibly arranged, and the flexible portion can abut against the inner wall of the filter tank 151. The cleaning brush 24 can rotate around its rotation axis in the filter tank 151, and its rotation axis can be its own central axis, and the cleaning brush 24 brushes the inner wall of the accommodating tank 111 by rotating.

[0116] Combination Figure 23-Figure 25 The top of the cleaning brush 24 is provided with a propulsion part 241. The water in the end cover 14 impacts the propulsion part 241 during the process of being introduced into the filter tank 151, so that the propulsion part 241 pushes the cleaning brush 24 to rotate, so that the cleaning brush 24 scrubs the inner wall of the filter tank 151 by rotating. The propulsion part 241 can be provided in a plate shape. The water in the end cover 14 impacts one side of the propulsion part 241 during the process of being introduced into the filter tank 151, so that the propulsion part 241 generates a force in the circumferential direction of the cleaning brush 24, thereby causing the cleaning brush 24 to rotate.

[0117] Specifically, in order to enable the impact of the water flow to cause the cleaning brush 24 to rotate, the flow direction of the water flow can have a certain angle with the vertical direction, so that under the impact of the water flow, a certain force is generated on the propulsion part 241 in the horizontal direction, so that the propulsion part 241 drives the cleaning brush 24 to rotate.

[0118] In summary, in the above embodiment, the propulsion part 241 is provided on the top of the cleaning brush 24, and the water flow guided by the end cover 14 is used to impact the propulsion part 241, thereby realizing the rotation of the cleaning brush 24 so that the cleaning brush 24 can clean the inner wall of the filter tank 151. Therefore, this embodiment can realize the automatic driving of the cleaning brush 24 by guiding the water to the filter tank 151, thereby realizing the automatic cleaning of the filter tank 151 by the cleaning brush 24, thereby preventing the filter tank 151 from being blocked by debris, so as to ensure the filtering efficiency of the filter element 15.

[0119] Fig.26 yes Fig. 22 A top view of the water distribution member 25 in FIG. Fig. 27 yes Fig.26 A schematic structural diagram of the water distribution member 25 in another viewing angle.

[0120] Combination Fig.21 , Fig. 22 as well as Fig.26 as well as Fig. 27 In some specific embodiments, the filter device 10 is not provided with the cleaning component 16 in the above embodiment, but is provided with a water dividing component 25, which is arranged at the bottom of the end cover 14, so that the water in the end cover 14 can enter the water dividing component 25.

[0121] Specifically, the water divider 25 can be arranged roughly in an annular shape, and the outer wall of the top of the water divider 25 is in contact with the inner wall of the accommodating groove 111, so that the water divider 25 seals the opening at the lower end of the water guide groove 143 of the end cover 14, so that the water entering the water guide groove 143 can only be discharged through the water divider 25. Fig. 27 The outer wall of the top of the water distribution member 25 may be provided with an external thread, and the inner wall of the bottom of the end cover 14 may be correspondingly provided with an internal thread, and the water distribution member 25 is screwed on the inner wall of the end cover 14 to achieve relative fixation.

[0122] Combination Fig.21 as well as Fig.26 The water diverter 25 is provided with a water diverter groove 251. When the water diverter 25 is provided at the bottom of the end cover 14, the water guide groove 143 is connected with the water diverter groove 251, so that the water guide groove 143 guides water into the water diverter groove 251. The bottom wall of the water diverter groove 251 is provided with a water diverter port 252. The water in the end cover 14 is guided into the water diverter groove 251 and guided out from the water diverter port 252. The water guided out from the water diverter port 252 is used to impact the propulsion part 241 to make the cleaning brush 24 rotate.

[0123] Specifically, there are multiple water diversion ports 252 to effectively guide the water in the water diversion tank 251. The water diverted from the water diversion port 252 can present a certain angle with the vertical direction before flowing to the propulsion unit 241. At this time, this can be achieved by setting the specific shape of the water diversion port 252. For example, the depth direction of the water diversion port 252 is set to be at a certain angle with the vertical direction, so that the water flowing out of the water diversion port 252 is at a certain angle with the vertical direction. Of course, it can also be achieved by setting a water guide structure below the water diversion port 252 to guide the water flow. Even if the water flow diverted from the water diversion port 252 is vertically downward, the water flow can be at a certain angle with the vertical direction before flowing to the propulsion unit 241 through the water guide structure.

[0124] Combination Fig. 27In some specific embodiments, the water diversion member 25 is provided with a water guide portion 256, which is located below the water diversion port 252. The water guide portion 256 is used to guide the water discharged from the water diversion port 252 to the propulsion portion 241, so that the cleaning portion pushes the cleaning brush 24 to rotate. The water guide portion 256 can be arranged in a strip shape, and the water guide portion 256 can be arranged one-to-one with the water diversion port 252, so that the water flow discharged from each water diversion port 252 can be discharged from the water guide portion 256. In combination with the above content, the water guide portion 256 is a water guide structure. When the water guide portion 256 finally discharges the water discharged from the water diversion port 252, the discharged water flow will form a certain angle with the vertical direction, so that the discharged water flow can push the propulsion portion 241 in the horizontal direction, so that the cleaning brush 24 rotates.

[0125] Combination Fig. 27 In some specific embodiments, the bottom wall 253 of the water diversion member is protruding downward and is provided with a first annular wall 254, and the water diversion port 252 is provided on the bottom wall 253 of the water diversion member and is located outside the first annular wall 254. At this time, the bottom wall 253 of the water diversion member can be provided in an annular shape, so that the center of the bottom wall 253 of the water diversion member coincides with the center of the first annular wall 254. The water guide 256 is provided on the outer side wall of the first annular wall 254 and is located directly below the water diversion port 252. The outer side wall of the first annular wall 254 is the side wall of the first annular wall 254 away from the center of the bottom wall 253 of the water diversion member.

[0126] Specifically, the water guide 256 extends along the axial direction and the circumferential direction of the first annular wall 254 to be arranged in an arc shape, and the water guide 256 is used to guide the water guided out of the water diversion port 252 downward along the circumferential direction of the first annular wall 254. At this time, the water guide 256 is arranged in a strip shape, and one side wall of the water guide 256 faces the water diversion port 252, and then the water guided out of the water diversion port 252 is guided through the side wall. It should be understood that when the water guided out of the water diversion port 252 flows downward along the circumferential direction of the first annular wall 254, the water guided to the propulsion part 241 will form a certain angle with the vertical direction, so as to facilitate the propulsion part 241.

[0127] Fig.28 is a schematic diagram of the structure of the water distribution member 25 and the cleaning brush 24 in the assembled state. Fig.29 yes Fig.28 A cross-sectional view of the structure shown, Fig.30 yes Fig.29 Schematic diagram of the enlarged structure of area A in FIG.

[0128] Combination Fig.21 , Fig.23 as well as Fig.25In some specific embodiments, a second annular wall 242 is disposed on the top of the cleaning brush 24. The second annular wall 242 is disposed around the first annular wall 254 at intervals, and the water guide 256 is in contact with the inner side wall of the second annular wall 242. The radius of the second annular wall 242 is greater than the outer wall of the first annular wall 254, and the center of the second annular wall 242 can be coincident with the center of the first annular wall 254. In combination with the setting of the propulsion part 241, the propulsion part 241 can be disposed on the inner side wall of the second annular part 145. When a plurality of propulsion parts 241 are provided, the plurality of propulsion parts 241 can be arranged at intervals along the circumference of the second annular part 145.

[0129] Combination Fig.29 as well as Fig.30 When the water guiding portion 256 is in contact with the inner wall of the second annular wall 242, the first annular wall 254, the second annular wall 242 and the water guiding portion 256 form a guiding groove 255. The propulsion portion 241 is arranged on the inner wall of the second annular wall 242 and is located below the guiding groove 255. The guiding groove 255 receives the water guided out from the water diversion port 252 to impact the propulsion portion 241 on one side in the clockwise or counterclockwise direction.

[0130] Specifically, the opening of the guide groove 255 faces the water diversion port 252, so that the water guided out of the water diversion port 252 flows directly into the guide groove 255, so that the guide groove 255 guides the water flow to the propulsion part 241. In combination with the embodiment in which the propulsion part 241 is arranged in a plate shape, the side wall of the propulsion part 241 receiving the water flow can face the clockwise direction or the counterclockwise direction on the second annular part 145, that is, at this time, the water guided out of the guide groove 255 impacts the side of the propulsion part 241 in the clockwise or counterclockwise direction.

[0132] Combination Fig.31 and Fig.32 In some specific embodiments, the propulsion portion 241 includes an arc section 2411. Specifically, the propulsion portion 241 includes an arc section 2411 and a vertical section 2412 (separated by a dotted line in the figure), the vertical section 2412 extends in the vertical direction, the arc section 2411 is arranged in an arc shape, and the lower section of the vertical section 2412 is connected to the upper end of the arc section 2411.

[0133] Combination Fig.30, the arc-shaped inner side of the arc-shaped section 2411 faces the outlet of the guide groove 255 in a clockwise or counterclockwise direction, and at this time, the inner side of the arc-shaped section 2411 faces the outlet of the guide groove 255 in a counterclockwise direction. The outlet of the guide groove 255 guides water to the arc-shaped inner side, so that the propulsion part 241 drives the cleaning brush 24 to rotate. It should be understood that when the guide groove 255 guides water to the arc-shaped inner side, the water has a greater impact force on the arc-shaped inner side, thereby facilitating the cleaning brush 24 to rotate.

[0134] Combination Fig.24 The number of the propulsion parts 241 is multiple, and the multiple propulsion parts 241 are arranged at intervals in the circumferential direction of the second annular part 145. Fig. 27 The number of the water guide portions 256 is multiple, and the multiple water guide portions 256 are arranged at intervals in the circumferential direction of the first annular portion 144. Fig.30 , the water distribution member 25 is fixed to the end cover 14, and the cleaning brush 24 can rotate, and the propulsion part 241 will move relative to the water guide part 256. When the water guide part 256 guides water to the propulsion part 241 so that the cleaning brush 24 rotates, the water guided by the multiple water guide parts 256 will impact different propulsion parts 241, and the water guided by the multiple water guide parts 256 will impact the same side of the multiple propulsion parts 241 in the clockwise direction or counterclockwise direction, such as Fig.30 As shown, water guided out by the plurality of water guides 256 impacts one side of the plurality of propulsion parts 241 in the counterclockwise direction, that is, impacts the arc-shaped inner side of the arc-shaped section 2411 .

[0135] Combination Fig.21 as well as Fig.23 In some specific embodiments, the cleaning brush 24 includes a rotating shaft 243, a second annular wall 242 is arranged around the rotating shaft 243, and two ends of the propulsion part 241 are respectively connected to the second annular wall 242 and the rotating shaft 243. The two ends of the propulsion part 241 described here are the two ends of the propulsion part 241 in the horizontal direction, rather than the two ends in the vertical direction. The cleaning brush 24 may also include a spiral skeleton arranged on the rotating shaft 243 and bristles arranged on the spiral skeleton, and the bristles are in contact with the inner wall of the filter tank 151, so as to brush the inner wall of the filter tank 151 through the bristles.

[0136] Combination Fig. 27 The first annular portion 144 is surrounded to form a first rotation groove 257. The first rotation groove 257 is an annular groove. The diameter of the first rotation groove 257 is larger than the diameter of the rotation shaft 243, so that the top end of the rotation shaft 243 can be rotatably disposed in the first rotation groove 257. Fig.21 As shown, the outer wall of the top end of the rotating shaft 243 can be in contact with the inner wall of the first annular portion 144 , and the top wall of the top end of the rotating shaft 243 can be in contact with the bottom wall 253 of the water diversion element.

[0137] Combination Fig.21 In some specific embodiments, the bottom of the filter tank 151 is protruded with a mounting portion 155, and the mounting portion 155 is protruded relative to the bottom wall of the filter tank 151. It should be understood that in the embodiment where the elastic member 18 is provided, the configuration of the second connecting column 154 is similar to that of the mounting portion 155, but the height of the second connecting column 154 is higher than that of the mounting portion 155.

[0138] Combination Fig.25 The bottom of the rotating shaft 243 is provided with a second rotating groove 2431, and the opening of the second rotating groove 2431 is downward. Fig.21 When the cleaning brush 24 is disposed in the filter tank 151, the mounting portion 155 is disposed in the second rotation groove 2431, and the rotation shaft 243 can rotate relative to the mounting portion 155. It should be understood that at this time, the cleaning brush 24 is disposed in the first rotation groove 257 through the top, and the bottom is combined with the mounting portion 155 through the second rotation groove 2431, so that the cleaning brush 24 is relatively fixed. When the cleaning brush 24 rotates, the top of the rotation shaft 243 rotates in the first mounting groove 29, and the mounting portion 155 rotates relative to the second mounting groove 29 therein.

The specific arrangement of the housing 11, the end cover 14 and the filter element 15 can refer to the contents of the above embodiments. This embodiment also includes an overflow ring 26.

[0141] Specifically, the overflow ring 26 is sleeved on the end cover 14 and arranged on the outer periphery of the filter element 15. The overflow ring 26 can be specifically arranged at the bottom position of the end cover 14. Fig.36 When the end cover 14 is provided with the second annular portion 145, the overflow ring 26 can be provided below the second annular portion 145. Fig.38The inner wall of the overflow ring 26 may be provided with an internal thread, and the outer wall of the bottom of the end cover 14 may be provided with an external thread. The overflow ring 26 is fixed to the bottom of the end cover 14 by screwing. At this time, the top of the overflow ring 26 may be against the bottom wall of the second annular portion 145.

[0142] Fig.39 is a cross-sectional view of the filter device 10 when it is arranged in the housing 11, Fig.40 yes Fig.39 Schematic diagram of the enlarged structure of area D in FIG.

[0143] Combination Fig.39 as well as Fig.40 Specifically, the outer periphery of the overflow ring 26 abuts against the inner wall of the accommodating groove 111 , and the overflow ring 26 , the inner wall of the accommodating groove 111 and the end cover 14 together form an overflow cavity 27 .

[0144] Combination Fig.37 as well as Fig.38 , the end cover 14 includes a first water outlet 148 and a second water outlet 149. In combination with the embodiment in which the end cover 14 is provided with a water guide groove 143 and a water diversion groove 21, the first water outlet 148 is an opening of the water guide groove 143, that is, an opening of the bottom wall of the end cover 14, and the second water outlet 149 is provided on the bottom wall of the water diversion groove 21. At this time, the water diversion groove 21 and the water guide groove 143 are both the internal spaces of the end cover 14, the first water outlet 148 is used to guide the water in the end cover 14 into the filter tank 151, and the second water outlet 149 is used to guide the water in the end cover 14 into the containing tank 111.

[0145] In combination with the above-mentioned embodiment, the opening of the water diversion groove 21 is in contact with the side wall of the accommodating groove 111 to seal the contents of the water diversion groove 21, and the inner wall of the accommodating groove 111 is provided with a water diversion hole 22, which is connected to the water inlet pipe 121. The water diversion hole 22 is used to introduce external water into the water diversion groove 21, and then into the water guide groove 143 through the water diversion groove 21.

[0146] Combination Fig.39 as well as Fig.40 The second water outlet 149 is connected to the overflow chamber 27, so that the water in the end cover 14 can enter the overflow chamber 27 through the second water outlet 149. The overflow ring 26 has a water permeability and filtering function, and the water in the overflow chamber 27 can be filtered through the overflow ring 26. The filtered water can be directly introduced into the receiving groove 111 and then discharged by the receiving groove 111.

[0147] It should be understood that when the filter element 15 is blocked (i.e., when the filter tank 151 is blocked), the water in the filter tank 151 will be filled up and the end cover 14 will be filled up due to the continuous water flow from the outside into the filter tank 151. At this time, the water pressure in the end cover 14 will be greater than the preset water pressure. At this time, the water in the overflow chamber 27 is filtered through the overflow ring 26 and introduced into the receiving tank 111 and is discharged from the receiving tank 111. It should be understood that when the water pressure in the end cover 14 is less than the preset water pressure, the water in the end cover 14 will only be introduced into the filter tank 151 from the first water outlet 148, and the water in the end cover 14 will not be introduced into the overflow chamber 27 from the second water outlet 149.

[0148] In some specific embodiments, the filter device 10 includes a control valve (not shown), which is disposed at the second water outlet 149. When the filter tank 151 is blocked so that the water pressure at the control valve is greater than the preset water pressure, the control valve opens the second water outlet 149 to guide the water in the end cover 14 into the 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 so that all the water in the end cover 14 is guided into the filter tank 151 from the first water outlet 148. Of course, in other embodiments, in order to allow the water in the end cover 14 to be discharged from the second water outlet 149 only when the water pressure in the end cover 14 is greater than the preset water pressure, the peripheral wall of the second water outlet 149 can be set to be flexible and closed in the initial state, so that when the water pressure is greater than the preset water pressure, the water in the end cover 14 will squeeze the second water outlet 149 and thus the water in the end cover 14 will be discharged from the second water outlet 149.

[0149] In summary, by setting the overflow ring 26, when the filter element 15 is blocked, the water in the end cover 14 can be introduced into the receiving groove 111 through the overflow ring 26. Therefore, the problem of drainage failure and poor drainage caused by the blockage of the filter groove 151 can be avoided, and a good drainage effect can be ensured under the premise of ensuring a good filtering effect.

[0150] Specifically combined with the arrangement of the first annular portion 144 and the second annular portion 145 in the above embodiment, the second water outlet 149 can be arranged on the second annular portion 145. In order to ensure that there is still a good filtering and drainage effect when the filter element 15 is blocked, a plurality of second water outlets 149 can be provided, and the plurality of second water outlets 149 can be arranged at intervals in the circumferential direction of the second annular 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 outlet 149.

[0152] In combination with the arrangement of the first sealing ring 231 and the second sealing ring 232 in the above embodiment, in this specific embodiment, the filter device 10 includes a third sealing ring (not shown), which is arranged between the accommodating groove 111 and the overflow ring 26, and is used to seal the gap between the filter groove 151 and the overflow ring 26.

[0153] Combination Figure 40-Figure 43 The outer peripheral wall of the overflow ring 26 is provided with a third annular groove 261, and the opening of the third annular groove 261 faces the direction away from the middle of the overflow ring 26. The third sealing ring is flexibly arranged, and part of the third sealing ring is located in the third annular groove 261, and the top of the third sealing ring is convex relative to the opening of the third annular groove 261, so that the third sealing ring can directly abut against the inner wall of the accommodating groove 111, so that the third sealing ring plays the effect of sealing the gap between the overflow ring 26 and the inner wall of the accommodating groove 111.

[0154] Combination Figure 41-43 In some specific embodiments, the overflow ring 26 includes a cylindrical portion 262 and a third annular portion 263, wherein the third annular portion 263 is protruded relative to the cylindrical portion 262 and extends in the circumferential direction of the cylindrical portion 262. The cylindrical portion 262 is sleeved on the end cover 14, and the third annular portion 263 abuts against the inner wall of the accommodating groove 111. In combination with the above, the inner wall of the cylindrical portion 262 is provided with an internal thread, and the outer wall of the bottom of the end cover 14 is provided with an external thread, so that the cylindrical portion 262 is screwed on the external thread of the outer wall of the end cover 14 through the internal thread to achieve relative fixation. The third annular groove 261 is provided on the side of the third annular portion 263 away from the cylindrical portion 262, and at this time, the third sealing ring is provided between the inner wall of the accommodating groove 111 and the third annular portion 263.

[0155] In combination with the above, the third annular portion 263 may be provided with an arcuate filter slot 264, the opening of which is upward. There may be multiple arcuate filter slots 264, which are spaced apart in the circumferential direction of the third annular portion 263, and the arcuate filter slots 264 constitute a part of the filter cavity. Fig.43 The third annular portion 263 is provided with a filter screen 153, and the water in the overflow cavity 27 is discharged and filtered through the filter screen 153. Specifically, the filter screen 153 is provided at the bottom of the arc-shaped filter groove 264 and forms the bottom wall of the arc-shaped filter groove 264, and the water in the filter cavity is directly filtered through the filter screen 153 and then flows into the containing groove 111. Among them, the specific arrangement of the filter screen 153 can refer to the specific arrangement of the filter screen 153 in the filter element 15, and will not be repeated.

[0156] Combination Fig.34as well as Fig.35 In some specific embodiments, the filter element 15 includes a first filter element 156 and a second filter element 157. The first filter element 156 forms a first filter tank, and the second filter element 157 forms a second filter tank. The first filter element 156 is arranged in the second filter tank at intervals. The size of the filter hole on the first filter tank is larger than the size of the filter hole on the second filter tank. The water guide hole 161 is used to guide the water in the end cover 14 to the inner wall of the first filter tank 151.

[0157] It should be understood that the water discharged from the end cover 14 will directly enter the first filter tank, and the water filtered by the first filter tank will be directly introduced into the second filter tank, and then filtered by the second filter tank. The second filter tank 151 will introduce the filtered water into the containing tank 111 and then discharge it. Since the size of the filter hole of the first filter tank is relatively large, the first filter tank 151 can achieve initial filtration of the water and filter out larger debris. The filter hole of the second filter tank is relatively small, so that the water can be filtered more finely, thereby achieving a better filtering effect.

[0158] In combination with the embodiment of the overflow ring 26, the water discharged through the overflow ring 26 will be directly introduced into the gap between the outer wall of the second filter element 157 and the inner wall of the accommodating groove 111, and then flow to the bottom of the accommodating groove 111. In combination with the above content, in the embodiment with the cleaning member 16 and the elastic member 18, in the embodiment with the water dividing member 25 and the cleaning brush 24, the filter element 15 can also be set to include the first filter element 156 and the second filter element 157. For example, in Fig.34 and Fig.35 In the embodiment, the filter device 10 is provided with a cleaning member 16, and the water discharged from the cleaning member 16 directly cleans the inner wall of the first filter tank.

[0159] Fig.44 is a top view of the warning device disposed on the housing 11, Fig.45 yes Fig.44 The structure shown is a cross-sectional view along section line II, Fig.46 yes Fig.45 Schematic diagram of the enlarged structure of area E in FIG.

[0160] Combination Figure 44-Figure 46 In some specific embodiments, the filter device 10 includes a warning component 28, which is disposed in the housing 11 and is used to warn the user when the water level in the end cover 14 is higher than a preset water level. Specifically, a mounting groove 29 is provided at the top of the housing 11, and a connecting hole 31 is provided on the side wall of the receiving groove 111. The mounting groove 29 is connected to the end cover 14 through the connecting hole 31, so that the water in the end cover 14 can enter the mounting groove 29 through the connecting hole 31.

[0161] In combination with the above content, in an embodiment in which a water guide groove 21 is provided, the communication hole 31 may be communicated with the guide groove, thereby allowing water in the water guide groove 21 of the end cover 14 to enter the installation groove 29 .

[0162] Fig.47 yes Fig.44 A schematic diagram of the structure of an embodiment of the warning component 28, Fig.48 yes Fig.47 The top view of the warning assembly 28 is shown, Fig.49 yes Fig.48 A cross-sectional view of the structure shown along section line JJ.

[0163] Combination Figure 47-Figure 49 Specifically, the warning assembly 28 includes an outer cylinder 281 , a warning column 282 and a base 283 . The outer cylinder 281 is hollow and has a mounting through hole 2811 . The mounting through hole 2811 runs through the upper and lower ends of the outer cylinder 281 .

[0164] At least part of the warning column 282 is disposed in the mounting through hole 2811, and the bottom circumference of the warning column 282 abuts against the inner circumference of the mounting through hole 2811, so that the warning column 282 can move in the mounting through hole 2811. The mounting through hole 2811 includes a first hole section at the top and a second hole section below the first hole section, and the diameter of the first hole section is smaller than the diameter of the second hole section, and the bottom diameter of the warning column 282 is larger than the diameter of the remaining part. The circumference of the bottom of the warning column 282 contacts the inner wall of the second hole section, so that the bottom of the warning column 282 can slide in the second hole section, and due to the limitation of the first hole section, the warning column 282 will not slide out from the top of the mounting through hole 2811.

[0165] The base 283 is disposed at the bottom of the outer cylinder 281 and blocks the bottom opening of the installation through hole 2811. The base 283 is provided with a water guide hole 161, which is connected to the interior of the end cover 14 through the communication hole 31. In the initial state, the bottom of the warning column 282 is supported on the top of the base 283, and the entirety of the warning column 282 is located in the installation through hole 2811, that is, the warning column 282 does not extend out of the outer cylinder 281 or the housing 11 at this time.

[0166] In combination with the above, when the water pressure in the end cover 14 increases, the warning column 282 extends out of the mounting through hole 2811 and the housing 11 under the action of the water pressure. Since the water guide hole 161 is connected to the inside of the end cover 14, when the water pressure in the end cover 14 increases, the water at the water guide hole 161 will increase the force on the warning column 282, thereby causing the warning column 282 to move upward so that the warning column 282 extends out of the mounting through hole 2811, that is, extends out of the housing 11. At this time, the user can understand that the water pressure in the end cover 14 increases, and the increase in the water pressure in the end cover 14 generally means that the filter tank 151 is blocked, so the user can understand that the filter element 15 is blocked through the extension of the warning column 282. In order to ensure effective reminders to users, the color of the warning column 282 can be set to a more eye-catching color, for example, the color of the warning column 282 is set to yellow.

[0167] In some specific embodiments, the filter device 10 further includes an elastic member 18 (not shown), which is disposed in the mounting through hole 2811, with the top of the elastic member 18 abutting against the inner wall of the mounting through hole 2811, and the bottom of the elastic member 18 abutting against the warning member, so as to press the warning member against the base 283. When the water pressure in the end cover 14 increases so that the warning column 282 extends out of the mounting through hole 2811, the elastic member 18 is compressed, and when the water pressure in the end cover 14 decreases, the elastic force of the elastic member 18 causes the warning column 282 to retract.

[0168] Specifically, the bottom of the elastic member 18 can abut against the larger diameter portion of the bottom of the warning column 282, and the top of the elastic member 18 can abut against the top wall of the second hole segment. At this time, the elastic member 18 is arranged in the second hole segment and between the warning column 282 and the inner wall of the second hole segment. The elastic member 18 can be specifically arranged as a spring, and then sleeved on the outer wall of the warning column 282.

[0169] It should be understood that, through the provision of the elastic member 18, when the water pressure in the end cover 14 decreases to less than the preset water pressure, the warning column 282 automatically retracts, thereby allowing the user to know that the water pressure in the end cover 14 decreases, that is, the filter element 15 can drain water normally.

[0170] The housing 11 is also provided with an observation window 32, one side of which is located outside the housing 11 and the other side of which is located inside the receiving groove 111. The observation window 32 is made of a transparent material. The observation window 32 can be provided in a strip shape, and the length extension direction of the observation window 32 is consistent with the depth direction of the receiving groove 111. The user can observe the situation inside the receiving groove 111 through the observation window 32, and further observe the filter element 15 and the water level in the receiving groove 111.

[0171] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
