Referring to fig. 8, 9 and 12-14, the filter device 10 includes a filter element 15, the filter element 15 is disposed in the accommodating groove 111 and below the end cap 14, and the filter element 15 is formed with a filter groove 151. The filter element 15 may be integrally located in the receiving groove 111 as shown in fig. 8 and 9. The filter element 15 and the end cap 14 may be in direct contact or may be connected by other structures. The opening formed by the filter element 15 is directed upwards and towards the end cap 14, thereby enabling water in the end cap 14 to be naturally guided by gravity into the filter tank 151. In combination with the above, that is, the opening of the filter tank 151 is directed to the lower opening of the water guiding tank 143, the water in the water guiding tank 143 is introduced into the filter tank 151 through the lower opening thereof.

After water in the end cap 14 is introduced into the filter tank 151, the water in the filter tank 151 is further filtered through the filter tank 151, and the water permeated in the filter tank 151 is introduced into the accommodating tank 111 and is guided out of the accommodating tank 111. In combination with the above, water in the accommodating groove 111 is led out through the water outlet pipe 122. The filter 15 may be specifically configured in a cylindrical shape, and the accommodating groove 111 may be configured in a cylindrical shape, as shown in fig. 8 and 9, for example. A gap is formed between the outer wall of the filter 15 and the inner wall of the accommodating groove 111 at intervals to ensure that water led out of the filter groove 151 flows down from the gap without the inner wall of the accommodating groove 111 obstructing the flow of water led out of the filter groove 151.

It should be understood that synthetic garments are mostly non-biodegradable plastics, since they contain micro-plastics such as polyester fibres and acrylic fibres. The washing machine drain contains more microplastic, which refers to plastic fragments and particles with the diameter smaller than 5 mm. In some application scenarios, the pore size of the filter screen 153 is smaller than a preset pore size, so that the filter screen 153 can have a good filtering effect on the microfibers.

Fig. 15 is a schematic structural view of the cleaning member 16 in fig. 13, and fig. 16 is a sectional view of the cleaning member 16 shown in fig. 15 taken along a section line D-D.

Referring to fig. 13 and 14, the filter device 10 includes a cleaning member 16, and the cleaning member 16 is disposed at the bottom of the end cap 14. The top of the cleaning member 16 may be disposed in the end cap 14, that is, the top is disposed in the water guiding groove 143, and at this time, the outer peripheral wall of the top of the cleaning member 16 may be attached to the inner peripheral wall of the water guiding groove 143, so that water in the water guiding groove 143 can be completely guided into the cleaning member 16.

Referring to fig. 15 and 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 with respect to the vertical direction toward the direction approaching the inner wall of the filter tank 151, i.e., the depth direction of the water guide hole 161 is inclined toward the direction away from the center position of the water guide member. In the case where the filter apparatus 10 is normally placed, the height direction of the cleaning member 16 is the vertical direction. Referring to fig. 16, an included angle a is formed between the depth direction and the vertical direction of the water guide hole 161. When the number of the water guide holes 161 is plural, the angles between the plurality of water guide holes 161 and the vertical direction may be the same or different, and the angles between the plurality of water guide holes 161 shown in the drawings in the vertical direction are the same.

By the above arrangement, the water guide hole 161 is enabled to guide the water introduced from the end cap 14 into the cleaning member 16 to the inner wall of the filter tank 151, so that the inner wall of the filter tank 151 is washed by the water flow impact. Therefore, according to the filtering device 10 provided by the above embodiment of the present application, in the process of introducing the water to be filtered from the cleaning member 16 into the filtering tank 151, the water to be filtered directly washes the inner wall of the filtering tank 151 due to the arrangement of the water guiding hole 161, so as to avoid the impurities from blocking the filtering member 15, and further ensure a good filtering effect.

With continued reference to fig. 16, in some embodiments, cleaning member 16 includes a cleaning bottom wall 162 and a cleaning side wall 163, with cleaning bottom wall 162 disposed about cleaning side wall 163 to form a cleaning tank 164. Wherein the cleaning bottom wall 162 may be provided in a circular shape, and the cleaning side wall 163 is provided in a circular shape. The water guide hole 161 is provided on the washing bottom wall 162, and water in the end cap 14 is introduced into the washing tub 164 to be guided out from the water guide hole 161.

In combination with the arrangement of the water guide groove 143 in the above embodiment and fig. 14, the water guide groove 143 and the cleaning groove 164 together constitute the water guide chamber 17 when the cleaning side wall 163 of the cleaning member 16 is adhered to the inner wall of the water guide groove 143. The water inlet 142 is located above the washing member 16, and the water inlet 142 introduces water into the water guide chamber 17 to be guided out of the water guide hole 161. That is, the water introduced into the water guide chamber 17 through the water inlet 142 is guided out from the water guide hole 161 so as to enter the filter tank 151 from the water guide hole 161, thereby ensuring a good filtering effect.

In some embodiments, the water guide holes 161 are divided into at least two groups, and 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 spaced apart from each other. Referring to fig. 15 and 16, the water guide holes 161 are divided into two groups, and each group of water guide holes 161 includes four water guide holes 161, and the four water guide holes 161 are disposed at intervals.

Specifically, the plurality of water guide holes 161 in each group may be arranged in a ring shape, and the ring shape may be a closed shape, and may be circular, elliptical, rectangular, or the like. In combination with the embodiment in which the cleaning bottom wall 162 is circularly disposed, the plurality of water guiding holes 161 in each group may be circularly disposed, and each water guiding hole 161 is disposed in an arc shape.

The two sets of water guide holes 161 may be arranged in a ring shape at intervals, and the depth direction of the water guide holes 161 is inclined with respect to the vertical direction toward the outside of the ring shape. When the two sets of water guide holes 161 are arranged in a circular shape, the two circles may be concentrically arranged and have different radii, and at this time, the depth direction of the water guide holes 161 is inclined in a direction away from the center of the circle.

It should be appreciated that by arranging the water guide holes 161 in a plurality of groups, water in the cleaning tank 164 can be more rapidly guided into the filter tank 151, and the problem of poor water guide in the filter tank 151 is avoided. By arranging the water guide holes 161 of each group in a ring shape, the water guided out by the water guide holes 161 is diffused towards the periphery, and then the inner wall of the filter tank 151 is completely washed.

In some embodiments, the filter device 10 includes an elastic member 18, and the elastic member 18 connects the end cap 14 and the filter 15, and the elastic member 18 is capable of being elastically deformed in a vertical direction and/or a horizontal direction, in conjunction with fig. 8, 9 and 13 and 14.

Specifically, the elastic member 18 may be a structure capable of being elastically deformed, such as a spring, a shrapnel, or the like, and the elastic member 18 is shown as a spring in the drawings. The top end of the elastic element 18 can be connected with the bottom end of the end cover 14, the bottom end of the elastic element 18 can be connected with the filter element 15, and the end cover 14 and the filter element 15 can be connected only through the elastic element 18, so that the filter element 15 is fixed on the end cover 14 through the elastic element 18. Of course, in other embodiments, other structures may be provided between the end cap 14 and the elastic member 18, and the other structures may also connect the end cap 14 and the filter element 15.

It will be appreciated that when water in the end cap 14 is introduced into the filter tank 151, the water will impact the filter tank 151 due to gravity, thereby causing the filter element 15 to elastically deform the elastic element 18 to shake the filter element 15. Specifically, the elastic member 18 may be elastically deformed only in the vertical direction so that the filter member 15 is vibrated in the vertical direction, the elastic member 18 may be elastically deformed only in the horizontal direction so that the filter member 15 is vibrated in the horizontal direction, and the elastic member 18 may be simultaneously elastically deformed in the vertical direction and the horizontal direction so that the filter member 15 is simultaneously vibrated in the vertical direction and the horizontal direction.

In combination with the above, by the arrangement of the elastic member 18, during the process of introducing the water in the end cover 14 into the filter element 15, the filter element 15 drives the elastic member 18 to elastically deform due to the gravity of the water, so that the filter element 15 shakes.

Referring to fig. 37 and 38, the end cap 14 includes a first water outlet 148 and a second water outlet 149. In connection with the embodiment in which the end cover 14 is provided with the water guide groove 143 and the water guide 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 in the bottom wall of the water guide groove 21. At this time, the water guide groove 21 and the water guide groove 143 are both the inner space of the end cover 14, the first water outlet 148 is for introducing water in the end cover 14 into the filter tank 151, and the second water outlet 149 is for introducing water in the end cover 14 into the accommodating groove 111.

In combination with the above embodiment, the opening of the water-guiding groove 21 is attached to the side wall of the accommodating groove 111 to seal the content of the water-guiding groove 21, the inner wall of the accommodating groove 111 is provided with the water-guiding hole 22, the water-guiding hole 22 is communicated with the water inlet pipe 121, and the water-guiding hole 22 is used for guiding the external water into the water-guiding groove 21, and then into the water-guiding groove 143 through the water-guiding groove 21.

Referring to fig. 39 and 40, the second water outlet 149 communicates with the overflow chamber 27, thereby allowing water in the end cap 14 to enter the overflow chamber 27 through the second water outlet 149. The overflow ring 26 has a water permeable filtering function, water in the overflow cavity 27 can be filtered through the overflow ring 26, and the filtered water can be directly led into the accommodating groove 111 and led out by the accommodating groove 111.

It should be understood that when the filter element 15 is blocked (i.e. when the filter tank 151 is blocked), since the external water flow continuously leads to the water in the filter tank 151, the water in the filter tank 151 fills and fills the end cap 14, at this time, the water pressure in the end cap 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 led into the accommodating groove 111 and led out from the accommodating groove 111. It will be appreciated that when the water pressure within the end cap 14 is less than the predetermined water pressure, water within the end cap 14 will only be directed from the first water outlet 148 into the filter tank 151 and water within the end cap 14 will not be directed from the second water outlet 149 into the overflow chamber 27.

In some embodiments, the filter apparatus 10 includes a control valve (not shown) disposed at the second water outlet 149, and when the filter tank 151 is blocked such that the water pressure at the control valve is greater than a predetermined water pressure, the control valve opens the second water outlet 149 to introduce the water in the end cap 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 water in the end cap 14 is introduced into the filter tank 151 from the first water outlet 148. Of course, in other embodiments, in order to enable the water in the end cover 14 to be led out from the second water outlet 149 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 may be set to be flexible and be in a closed state in the initial state, so that when the water pressure is greater than the preset water pressure, the water in the end cover 14 may press the second water outlet 149 and the water in the end cover 14 may be led out from the second water outlet 149.

In summary, by the arrangement of the overflow ring 26, when the filter element 15 is plugged, water in the end cover 14 can be led into the accommodating groove 111 through the overflow ring 26. Therefore, the problem that the drainage is not filtered and is not smooth due to the blockage of the filter tank 151 can be avoided, and a good drainage effect can be ensured on the premise of ensuring a good filtering effect.

In particular, in the above embodiment, the first annular portion 144 and the second annular portion 145 are disposed, and the second water outlet 149 may be disposed on the second annular portion 145. In order to ensure that the filter element 15 has better filtering and draining effects when blocked, the second water outlets 149 may be provided with a plurality of second water outlets 149, and the plurality of second water outlets 149 may 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 sufficiently led out through the second water outlets 149.

Referring to fig. 40 to 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 away from the middle of the overflow ring 26. The third sealing ring is flexibly arranged, part of the third sealing ring is located in the third annular groove 261, the top of the third sealing ring is arranged relative to the opening of the third annular groove 261 in a protruding mode, and then the third sealing ring can directly abut against the inner wall of the accommodating groove 111, and further the third sealing ring plays a role in sealing a gap between the overflow ring 26 and the inner wall of the accommodating groove 111.

Referring to fig. 41-43, in some embodiments, the overflow ring 26 includes a cylindrical portion 262 and a third annular portion 263, the third annular portion 263 being disposed in a convex manner with respect to the cylindrical portion 262 and extending in a 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 by the internal thread to achieve relative fixation. The third annular groove 261 is disposed at a side of the third annular portion 263 remote from the cylindrical portion 262, and at this time, the third seal ring is disposed between the inner wall of the accommodation groove 111 and the third annular portion 263.

In combination with the above, the third annular portion 263 may be provided with an arc-shaped filter groove 264, and an opening of the arc-shaped filter groove 264 is upward. The number of the arc-shaped filter grooves 264 may be plural, and the plural arc-shaped filter grooves 264 are arranged at intervals in the circumferential direction of the third annular portion 263, in which case the arc-shaped filter grooves 264 constitute a part of the filter chamber. Referring to fig. 43, a filter screen 153 is provided on the third ring portion 263, and water in the overflow chamber 27 is guided out through the filter screen 153 and filtered. Specifically, the filter screen 153 is disposed at the bottom of the arc-shaped filter tank 264 and forms the bottom wall of the arc-shaped filter tank 264, and water in the filter cavity can directly pass through the filter screen 153 to be filtered and then flows into the accommodating tank 111. The specific arrangement of the filter 153 in the filter 15 may refer to the specific arrangement of the filter 153, and will not be described herein.

In some embodiments, referring to fig. 34 and 35, the filter 15 includes a first filter 156 and a second filter 157, the first filter 156 forming a first filter tank and the second filter 157 forming a second filter tank. The first filter 156 is disposed in the second filter tank at intervals, the size of the filter hole on the first filter tank is larger than that on the second filter tank, and the water guide hole 161 is used for guiding the water in the end cover 14 to the inner wall of the first filter tank 151.

It should be understood that the water led out from the end cap 14 directly enters the first filter tank, the water filtered by the first filter tank is directly led into the second filter tank, and then filtered by the second filter tank, and the water filtered by the second filter tank 151 is led into the accommodating tank 111 and then led out. Because the size of the filtering hole of the first filtering tank is larger, the first filtering tank 151 performs primary filtering on water and filters larger impurities. The filtration pore of the second filter tank is smaller, so that finer filtration of water is realized, and further, a better filtration effect is realized.

In combination with the above embodiment of the arrangement of the overflow ring 26, the water led out through the overflow ring 26 is directly led into the gap between the outer wall of the second filter 157 and the inner wall of the receiving groove 111, and then flows to the bottom of the receiving groove 111. In combination with the above, in the embodiment provided with the cleaning member 16, the elastic member 18, the filter member 15 may be provided in the form of including the first filter member 156 and the second filter member 157 in the embodiment provided with the water dividing member 25, the cleaning brush 24. For example, in fig. 34 and 35, the filter device 10 is provided with the cleaning member 16, and at this time, the water led out from the cleaning member 16 directly cleans the inner wall of the first filter tank.

Fig. 44 is a plan view of the warning device provided on the housing 11, fig. 45 is a sectional view of the structure shown in fig. 44 taken along a sectional line I-I, and fig. 46 is an enlarged schematic view of the structure of a region E in fig. 45.

44-46, in some embodiments, the filter apparatus 10 includes a warning assembly 28, the warning assembly 28 being disposed within the housing 11, the warning assembly 28 being configured to alert a user when the water level within the end cap 14 is above a predetermined water level. Specifically, the top of the housing 11 is provided with a mounting groove 29, and the side wall of the accommodation groove 111 is provided with a communication hole 31, and the mounting groove 29 communicates with the end cap 14 through the communication hole 31, so that water in the end cap 14 can enter the mounting groove 29 through the communication hole 31.

In combination with the above, in the embodiment provided with the water guide groove 21, the communication hole 31 may communicate with the water guide groove, thereby allowing water in the water guide groove 21 of the end cap 14 to enter into the installation groove 29.

Fig. 47 is a schematic diagram of an embodiment of the alert assembly 28 of fig. 44, fig. 48 is a top view of the alert assembly 28 of fig. 47, and fig. 49 is a cross-sectional view of the structure of fig. 48 taken along section line J-J.

Referring to fig. 47-49, in particular, the warning unit 28 includes an outer cylinder 281, a warning post 282, and a base 283, and the outer cylinder 281 is hollow with a mounting through hole 2811, and the mounting through hole 2811 penetrates both upper and lower ends of the outer cylinder 281.

At least part of the warning post 282 is provided in the mounting through hole 2811, and the bottom peripheral side of the warning post 282 abuts against the inner peripheral wall of the mounting through hole 2811, so that the warning post 282 can move in the mounting through hole 2811. The mounting through hole 2811 includes a first hole section at an upper portion and a second hole section located below the first hole section, the first hole section having a smaller diameter than the second hole section, and the bottom of the warning post 282 having a larger diameter than the rest. The peripheral wall of the bottom of the warning post 282 contacts the inner wall of the second aperture segment, thereby enabling the bottom of the warning post 282 to move in the second aperture Duan Nahua, and the warning post 282 does not slide out of the top of the mounting through aperture 2811 due to the limited position of the first aperture segment.

The base 283 is provided at the bottom of the outer cylinder 281 and closes the bottom opening of the mounting through hole 2811, and the base 283 is provided with a water guide hole 161, the water guide hole 161 communicating with the inside of the end cap 14 through the communication hole 31. In the initial state, the bottom of the warning post 282 is supported on the top of the base 283, and the warning post 282 is entirely located in the mounting through hole 2811, i.e., the warning post 282 does not protrude from the outer cylinder 281 nor from the housing 11.

In combination with the above, when the water pressure in the end cap 14 increases, the warning post 282 protrudes out of the mounting through hole 2811 and out of the housing 11 under the water pressure. Since the water guide hole 161 is communicated with 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 increases the force to the warning post 282, and the warning post 282 moves upward so that the warning post 282 protrudes out of the mounting through hole 2811, that is, out of the housing 11. At this time, the user can recognize that the water pressure in the end cap 14 increases, and the filter tank 151 is generally clogged, so the user can recognize that the filter 15 is clogged by the protrusion of the warning post 282. To ensure effective alert to the user, the alert post 282 may be colored a more striking color, such as the alert post 282 being colored yellow.

In some embodiments, the filtering device 10 further includes an elastic member 18 (not shown), the elastic member 18 is disposed in the mounting through hole 2811, the top end of the elastic member 18 abuts against the inner wall of the mounting through hole 2811, and the bottom end of the elastic member 18 abuts against the warning member to press the warning member against the base 283. Wherein, when the water pressure in the end cover 14 increases to make the warning post 282 extend 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 makes the warning post 282 retract.

Specifically, the bottom of the elastic member 18 may abut against the larger diameter portion of the bottom of the warning post 282, and the top of the elastic member 18 may abut against the top wall of the second hole segment, where the elastic member 18 is disposed in the second hole segment and between the warning post 282 and the inner wall of the second hole segment. The elastic member 18 may be specifically configured as a spring, and further sleeved on the outer wall of the alarm post 282.

It will be appreciated that by the provision of the resilient member 18, when the water pressure within the end cap 14 is reduced to less than the predetermined water pressure, the warning post 282 is automatically retracted, thereby allowing the user to learn that the water pressure within the end cap 14 is reduced, i.e. that the filter 15 is able to drain normally.

The housing 11 is further provided with an observation window 32, one side of the observation window 32 is located outside the housing 11, the other side is located in the accommodating groove 111, and the observation window 32 is made of a transparent material. The observation window 32 may be disposed in a strip shape, and a length extending direction of the observation window 32 is consistent with a depth direction of the accommodating groove 111. The user can observe the condition inside the accommodating groove 111 through the observation window 32, and then observe the water level inside the filter 15 and the accommodating groove 111.

The foregoing is only the embodiments of the present application, and therefore, the patent scope of the application is not limited thereto, and all equivalent structures or equivalent processes using the descriptions of the present application and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the application.
