Description

Technical Field

[0002] In garment processing equipment, the filter at the air outlet is a key component ensuring efficient operation. It primarily filters impurities such as fibers and lint from the airflow, preventing them from entering the air duct system. However, existing methods for cleaning filters have shortcomings: most equipment relies solely on the direct impact of water during washing or manual cleaning by the user, resulting in limited cleaning effectiveness. Due to insufficient water impact force and a single direction, it is difficult to thoroughly remove fine impurities adhering to the filter surface, leading to easy clogging. This, in turn, obstructs airflow, reduces drying efficiency, increases energy consumption, and may also accelerate wear and tear on internal components, increasing maintenance costs and shortening equipment lifespan.

This effectively peels off and removes impurities such as fibers and lint attached to the filter screen, fundamentally solving the problem of incomplete cleaning and easy clogging of the filter screen in the existing technology.

[0033] (2) Improved equipment operating efficiency and reliability: The automatic cleaning mechanism of transmission and cleaning components effectively ensures the smooth flow of air outlets and airflow; this directly improves the efficiency of the drying stage, shortens the drying time, and reduces the risk of equipment overload due to airflow blockage, thereby improving the overall working performance, energy utilization efficiency and long-term operating reliability of the machine.

[0034] (3) Ingenious structure and low cost: It creatively utilizes the inherent conditions of the equipment itself during operation. The water flow agitated by the rotation of the inner cylinder serves as the driving force source. The kinetic energy of the water is converted into the mechanical energy of the cleaning action through the transmission components. This avoids the use of additional electric motors or complex control systems, simplifies the structure, reduces production costs and subsequent maintenance costs, and improves the durability of the system.

[0035] (4) Extended service life of filter screen and equipment: Continuous automatic cleaning prevents impurities from accumulating and hardening on the filter screen for a long time, reduces the load on the filter screen, and helps to extend the service life of the filter screen itself; at the same time, the unobstructed air duct reduces the workload of the equipment, which also indirectly extends the service life of the fan and other related core components.

[0051] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0054] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0055] The existing methods for cleaning the air outlet filter in garment processing equipment have the following shortcomings: relying solely on the direct impact of water flow during the washing process or manual cleaning by the user has limited cleaning effect and makes it difficult to completely remove the fine impurities attached to the surface of the filter, which leads to easy clogging of the filter, resulting in obstructed airflow, reduced drying efficiency and increased energy consumption.

[0056] This invention creatively provides a garment processing device, including an outer cylinder, an inner cylinder, a filter screen, and a cleaning component. The outer cylinder has an air outlet formed in its wall, and the inner cylinder is rotatably disposed inside the outer cylinder. The filter screen is disposed at the air outlet and is used to filter the airflow discharged from the outer cylinder through the air outlet. The cleaning component is disposed at the air outlet. The filter screen and the cleaning component are arranged to move relative to each other. When the inner cylinder rotates, it drives the water flow in the outer cylinder to move. One of the filter screen and the cleaning component can move relative to the other under the action of the water flow in the outer cylinder, thereby the cleaning component can clean the filter screen.

[0057] Without user intervention or external power input, it can automatically and continuously clean the filter screen, effectively stripping and removing impurities such as fibers and lint attached to the filter screen, fundamentally solving the problems of incomplete filter screen cleaning and easy clogging in existing technologies; it effectively ensures the unobstructed air outlet and ensures smooth airflow; this directly improves the efficiency of the drying stage and shortens the drying time.

[0058] Example 1

[0059] like Figs. 1a to 7b As shown, this embodiment proposes a clothing processing device. Preferably, the clothing processing device is a drum washing machine or a drum washer-dryer, and the rotation axis of the washing machine is in the horizontal direction.

[0060] Garment processing equipment includes:

[0061] The outer cylinder 11 and the inner cylinder 12 are provided. The outer cylinder 11 has an air outlet 112 formed on its wall. The inner cylinder 12 is rotatably disposed inside the outer cylinder 11. Specifically, the axis of the outer cylinder 11 and the axis of the inner cylinder 12 are both horizontal. The outer cylinder 11 includes a peripheral wall and a rear wall. The front end of the peripheral wall has an opening, and the rear side of the peripheral wall has a rear wall. An air outlet seat 111 is formed at the upper outer side of the peripheral wall. An air outlet 112 is formed inside the air outlet seat 111. The air outlet 112 connects the inside and outside of the outer cylinder 11 and can discharge the airflow inside the outer cylinder 11. The inner cylinder 12 is used to hold clothing.

[0062] The filter screen 13 is installed at the air outlet 112 and is used to filter the airflow discharged from the air outlet inside the outer cylinder.

[0063] The cleaning component 21 is located at the air outlet 112 and contacts the filter screen 13 for cleaning the filter screen 13. Specifically, along the radial direction of the outer cylinder 11, the cleaning component 21 is located on the side of the air outlet 112 closer to the inner cylinder 12, or on the side of the air outlet 112 away from the inner cylinder 12; it can be flexibly adjusted according to cleaning needs. When the cleaning component 21 is located on the side of the air outlet 112 away from the inner cylinder 12, it can clean the filter screen 13 from top to bottom; when the cleaning component 21 is located on the side of the air outlet 112 closer to the inner cylinder 12, it can clean the filter screen 13 from bottom to top. The flexible design of the cleaning component 21 allows for a more comprehensive cleaning effect.

[0064] The filter screen 13 and the cleaning component 21 are movably arranged relative to each other, and the filter screen 13 and the cleaning component 21 are configured such that when the inner drum 12 rotates and drives the water flow in the outer drum 11, one of the filter screen 13 and the cleaning component 21 can move relative to the other under the action of the water flow in the outer drum 11, thereby the cleaning component 21 can clean the filter screen 13; that is, when the inner drum 12 rotates, it can drive the water flow in the outer drum 11, and under the action of the water flow in the outer drum 11, one of the filter screen 13 and the cleaning component 21 can move relative to the other, thereby the cleaning component 21 can clean the filter screen 13; during the washing or spin-drying process of the clothing processing equipment, the cleaning component 21 can clean the filter screen 13.

[0065] The following further explains the transmission component. The garment processing equipment also includes a transmission component, which is movably disposed at the air outlet 112. The transmission component is configured such that when the inner drum 12 rotates and drives the water flow in the outer drum 11, the transmission component can move under the action of the water flow in the outer drum 11.

[0066] One of the filter screen 13 and the cleaning component 21 is connected to the transmission component, and the other is fixedly installed relative to the air outlet 112;

[0067] When the transmission component moves under the action of water flow in the outer cylinder 11, the filter screen 13 and the cleaning component 21 move relative to each other, and the cleaning component 21 can clean the filter screen 13.

[0068] Preferably, the filter screen 13 is fixedly disposed relative to the air outlet 112, and the cleaning component 21 is connected to the transmission component, that is, the cleaning component 21 can move with the transmission component; the cleaning component 21 has a long strip structure.

[0069] Furthermore, a support member 23 is provided at the air outlet 112, and the support member 23 is fixedly installed relative to the air outlet 112; the transmission member is movably installed on the support member 23;

[0070] The transmission component includes a transmission connection part and a hydraulic action part; the transmission connection part is located near the filter screen 13 and is connected to one of the filter screen 13 and the cleaning component 21; the hydraulic action part is connected to the transmission connection part and is located near the inner cylinder 12, and is used to receive the force of water.

[0071] When the hydraulic action part is subjected to the force of the water flow in the outer cylinder 11, the transmission component moves relative to the support component 23, and causes the filter screen 13 and the cleaning component 21 to move relative to each other, thereby cleaning the filter screen 13 by the cleaning component 21.

[0072] During the washing or spin-drying process of the garment processing equipment, without user intervention or external power input, the cleaning component 21 and the filter screen 13 can automatically and continuously move relative to each other (such as scraping or brushing), thereby effectively peeling off and removing impurities such as fibers and lint attached to the filter screen 13.

[0073] The automatic cleaning mechanism of the transmission component and the cleaning component 21 effectively ensures the unobstructed air outlet 112 and the smooth airflow duct; this directly improves the efficiency of the drying stage, shortens the drying time, and reduces the risk of the equipment overloaded due to the clogging of the filter screen 13.

[0074] By converting the kinetic energy of the water flow into the mechanical energy of the cleaning action through the transmission components, the use of additional electric motors or complex control systems is avoided, which simplifies the structure and reduces production and subsequent maintenance costs.

[0075] Continuous automatic cleaning prevents impurities from accumulating and hardening on the filter screen 13 over a long period of time, reduces the load on the filter screen 13, helps extend the service life of the filter screen 13 itself, and also indirectly extends the service life of the fan and other related core components.

[0076] Example 2

[0077] As shown in Figure 1 to Fig. 4 As shown, based on Embodiment 1, this embodiment proposes that the transmission component is an impeller 22, which is rotatably disposed at the air outlet 112; the impeller 22 includes a rotating shaft 221 and blades 222, and the rotating shaft 221 is rotatably disposed on the support member 23 through a bearing;

[0078] The end of the rotating shaft 221 away from the inner cylinder 12 is provided with a transmission connection part; the end of the rotating shaft 221 near the inner cylinder 12 is provided with a blade 222, which is a hydraulic action part; there are multiple blades 222, and the multiple blades 222 are arranged sequentially along the circumference of the rotating shaft 221 at the end of the rotating shaft 221 near the inner cylinder 12.

[0079] The impeller 22 can rotate under the action of the water flow in the outer cylinder 11 when the inner cylinder 12 rotates; that is, one axial end of the rotating shaft 221 is provided with a transmission connection part, and the other axial end of the rotating shaft 221 is provided with blades 222.

[0080] Among them, the axis of the rotating shaft 221 and the center line of the air outlet 112 are collinear, and the center line of the air outlet 112 is a line that passes through the center of the air outlet 112 and is parallel to the radial direction of the outer cylinder 11.

[0081] Furthermore, the inner cylinder 12 can rotate in a fixed direction or rotate alternately in both directions.

[0082] During the washing and / or spin-drying process of the clothing processing equipment, the inner drum 12 rotates and drives the water flow in the outer drum 11. The water flow acts on the blades 222, causing the blades 222 and the rotating shaft 221 to rotate relative to the support 23, and causing the filter screen 13 and the cleaning component 21 to rotate relative to each other.

[0083] Specifically, the rotational power of the blade 222 comes from the centrifugal force generated during the rotation of the inner cylinder 12. The water flow inside the outer cylinder 11 flies away and impacts the blade 222, causing the blade 222 and the rotating shaft 221 to rotate synchronously.

[0084] One of the filter screen 13 and the cleaning component 21 is connected to the rotating shaft 221; preferably, the cleaning component 21 is connected to the rotating shaft 221.

[0085] First, when the end of the rotating shaft 221 away from the inner cylinder 12 is connected to the filter screen 13, the cleaning component 21 is fixedly set relative to the air outlet 112, the blade 222 rotates due to the impact of the water flow in the outer cylinder 11, the rotating shaft 221 rotates with the filter screen 13, and the cleaning component 21 can clean the filter screen 13.

[0086] Secondly, when the end of the rotating shaft 221 away from the inner cylinder 12 is connected to the cleaning component 21, the filter screen 13 is fixed relative to the air outlet 112, the blades 222 are rotated by the impact of the water flow in the outer cylinder 11, the rotating shaft 221 rotates with the cleaning component 21, and the cleaning component 21 can clean the filter screen 13.

[0087] Furthermore, the blades 222 are arranged in a spiral shape, which optimizes the impact efficiency of the water flow on the blades 222. The blades 222 are axial flow blades, and the plane of the axial flow blades forms a certain angle of attack with the axis of the rotating shaft 221. This can efficiently convert the axial kinetic energy of the water flow into the rotational torque of the rotating shaft 221. Therefore, it can obtain a large rotational torque under a small water flow impact, thereby driving the cleaning component 21 to rotate more efficiently. This design not only improves the cleaning efficiency, but also reduces the dependence on the water flow intensity, ensuring that the filter screen 13 can be effectively cleaned in different washing stages (such as washing, rinsing, and dehydration).

[0088] The blade 222 may be a centrifugal blade or a mixed-flow blade composed of axial and centrifugal blades; combining the advantages of axial and centrifugal blades, the blade 222 can still achieve high rotational efficiency under small water flow impact; it enhances the utilization rate of water energy, especially in the case of weak water flow at the beginning of washing, it can also ensure stable start of impeller 22 and improve cleaning response speed.

[0089] The following describes the structure required for the stable and continuous rotation of the blade 222. The garment processing equipment also includes a baffle plate 24, which is mounted on the support member 23. The baffle plate 24 surrounds the outer periphery of the impeller 22 and has a notch. Water flow in the outer cylinder 11 can impact the blade 222 through the notch, ensuring the continuous and stable rotation of the impeller 22. That is, the baffle plate 24 only surrounds a part of the impeller 22, and the notch penetrates the baffle plate 24 in the depth direction.

[0090] Furthermore, the water baffle 24 has an arc-shaped structure;

[0091] Preferably, the baffle plate 24 has an arc-shaped structure and a superior arc structure; the central angle of the baffle plate 24 is in the range of 270°-330°, and the baffle plate 24 is adapted to the outer circumferential contour of the impeller 22; the notch position is directly opposite to the direction of water flow impacting the impeller 22, ensuring that the water flow in the outer cylinder 11 can accurately impact the blades 222 through the notch.

[0092] In some embodiments, the baffle plate 24 is rotatably mounted on the support member 23, and the rotation axis of the baffle plate 24 is collinear with the center line of the air outlet 112; when the inner cylinder 12 rotates alternately in both directions, the position of the notch of the baffle plate 24 changes alternately and faces the water flow, so that the water flow can enter the interior of the baffle plate 24 through the notch and impact the blades 222; that is, when the inner cylinder 12 rotates alternately in both directions, the water flow can drive the blades 222 to rotate, thereby cleaning the filter screen 13.

[0093] The specific structure of the cleaning component 21 is described below. The cleaning component 21 is a brush, which includes a support and bristles. The support extends radially along the air outlet 112, and the bristles are disposed on the support and in contact with the filter screen 13. The brush and the filter screen 13 move relative to each other, and impurities and fibers on the surface of the filter screen 13 are removed through friction and sweeping action. Preferably, the filter screen 13 is fixedly disposed relative to the air outlet 112, and the brush is movable relative to the air outlet 112.

[0094] In summary, the cleaning process of filter 13 is integrated throughout the entire washing and dehydration process of the garment processing equipment. As long as water flows from the outer drum 11 and impacts the impeller 22, the brush will continuously move and clean the filter 13 without requiring additional energy input. This design is not only energy-saving and environmentally friendly, but also ensures that the filter 13 is always clean, avoiding clogging problems. Through continuous cleaning, the problem of impurity accumulation on the surface of the filter 13 is effectively solved, and the service life of the filter 13 is significantly extended. At the same time, since the possibility of clogging of the filter 13 is reduced, the airflow efficiency is improved, further enhancing the drying effect.

[0095] By utilizing the water flow inside the outer cylinder 11 to drive the impeller 22 and brush when the inner cylinder 12 rotates, no additional energy input is required, resulting in significant energy-saving and environmental protection advantages. At the same time, the structure is simple, easy to install and maintain, reducing production and operating costs. It is suitable for drum-type garment processing equipment and can effectively solve the problem of low cleaning efficiency of the filter screen 13 in the existing technology, with broad market application prospects.

[0096] It not only achieves efficient cleaning of the air outlet 112 filter 13, but also significantly improves the performance and service life of the garment processing equipment, providing users with a more convenient and efficient washing experience.

[0097] Example 3

[0098] like Figs. 6 to 7b As shown, based on Embodiment 2, this embodiment proposes that the clothing treatment equipment also includes a spray head 3, which is located at the air outlet 112. Along the axial direction of the air outlet 112, the spray head 3 is positioned on the side of the filter screen 13 away from the inner cylinder 12, and the impeller 22 is positioned on the side of the filter screen 13 closer to the inner cylinder 12. The spray head 3 can spray water onto the filter screen 13 and the impeller 222. The impeller 222 can rotate under the action of the water flow from the spray head 3. That is, a portion of the water sprayed from the spray head 3 can clean the filter screen 13, and another portion of the water sprayed from the spray head 3 acts on the impeller 222, causing the impeller 22 to rotate. Consequently, the cleaning component 21 can clean the filter screen 13. The combination of cleaning by the spray head 3 and cleaning by the cleaning component 21 achieves a comprehensive and thorough cleaning of the filter screen 13.

[0099] Furthermore, the spray head 3 has an overall elongated structure, and a spray nozzle 332 is formed on the side of the spray head 3 facing the filter screen 13 for spraying water onto the filter screen 13 and the blades 222.

[0100] In this embodiment, the cleaning component 21 is fixedly arranged relative to the air outlet 112, and the filter screen 13 is rotatably arranged relative to the air outlet 112, that is, the impeller 22 can drive the filter screen 13 to rotate; in this way, the entire filter screen 13 can be flushed during the rotation of the filter screen 13, and the cleaning is more thorough; since the number of spray nozzles 332 is reduced, the speed of the sprayed water flow is greatly increased, and the force on the impeller 22 will also increase, which is more conducive to improving the cleaning effect of the filter screen 13;

[0101] Preferably, the air outlet 112 is circular, and both the spray head 3 and the cleaning component 21 extend radially along the air outlet 112. The length of the spray head 3 is adapted to the radius of the air outlet 112, and the length of the cleaning component 21 is adapted to the radius or diameter of the air outlet 112.

[0102] Specifically, the spray head 3 includes a mounting part 31, a water inlet part 32, and a spraying part 33 arranged sequentially. The mounting part 31 is mounted on the air outlet seat 111. The water inlet part 32 forms a water inlet channel 321, and the spraying part 33 forms a spraying chamber 331. One end of the water inlet channel 321 is connected to a water source, and the other end of the water inlet channel 321 is connected to the spraying chamber 331. The side wall of the spraying chamber 331 facing the filter screen 13 has spray nozzles 332. Multiple spray nozzles 332 are provided and spaced apart on the side wall of the spraying chamber 331 facing the filter screen 13.

[0103] Example 4

[0104] Based on Embodiment 1, this embodiment proposes that the transmission component is a swing frame, which is oscillatingly arranged at the air outlet 112 around the axis of the outer cylinder 11. The swing frame includes a transmission connecting wall and a hydraulic action wall. The transmission connecting wall is provided with a transmission connecting part, and the hydraulic action wall is provided with a hydraulic action part.

[0105] The swing frame is configured such that when the inner cylinder 12 rotates and drives the water flow in the outer cylinder 11, the swing frame can swing back and forth at the air outlet 112 under the action of the water flow in the outer cylinder 11, thereby causing the cleaning component 21 to move back and forth relative to the filter screen 13, and thus the cleaning component 21 cleans the filter screen 13.

[0106] Furthermore, there are two hydraulic action walls, which are arranged opposite each other in the circumferential direction of the outer cylinder 11. Each hydraulic action wall is provided with a hydraulic action part. When the inner cylinder 12 alternates between forward and reverse rotation, the water flow in the outer cylinder 11 alternately acts on the two hydraulic action parts, causing the swing frame to move back and forth at the air outlet 112, which in turn carries the cleaning component 21 to swing back and forth, so that the cleaning component 21 can clean the filter screen 13.

[0107] When the inner cylinder 12 rotates in the forward direction, water acts on one hydraulic part, causing the swing frame to rotate in the forward direction, thereby causing the cleaning component 21 and the filter screen 13 to move relative to each other to clean the filter screen 13; when the inner cylinder 12 rotates in the reverse direction, water acts on another hydraulic part, causing the swing frame to rotate in the reverse direction, thereby causing the cleaning component 21 and the filter screen 13 to move relative to each other to clean the filter screen 13.

[0108] Preferably, the extension direction of the swing frame is parallel to the axis of the outer cylinder 11, and the transmission connecting wall is set close to the filter screen; in the circumferential direction of the outer cylinder 11, two hydraulically acting walls are respectively set on both sides of the transmission connecting wall.

[0109] The structure of the support member 23 and the swing frame is described below. The support member 23 is a frame structure and is arranged around the air outlet 112 on the side near the inner cylinder 12. Along the axial direction of the outer cylinder 11, the support member 23 includes a first frame and a second frame arranged opposite to each other. The first frame forms a first arc-shaped groove, and the second frame forms a second arc-shaped groove. Both the first arc-shaped groove and the second arc-shaped groove are coaxially arranged with the outer cylinder 11. The swing frame is a rod-shaped structure. One end of the swing frame is slidably arranged in the first arc-shaped groove, and the other end of the swing frame is slidably arranged in the second arc-shaped groove. The swing frame can slide along the first arc-shaped groove and the second arc-shaped groove under the action of water flow in the outer cylinder 11.

[0110] Furthermore, a spring is connected between the swing frame and the support 23; when the inner cylinder 12 rotates, the water flow in the outer cylinder 11 and the spring work together to swing the swing frame, causing the swing frame to swing back and forth near the air outlet 112, and the cleaning component 21 moves back and forth at the air outlet 112 to clean the filter screen 13.

[0111] During the drying process of the clothing processing equipment, the swing frame can avoid the air outlet 112 to prevent affecting the airflow at the air outlet 112.

[0112] Example 5

[0113] Based on any one of the embodiments 1 to 4, this embodiment proposes that a spray channel is provided on the inner side wall of the outer cylinder 11 and around the outer side of the air outlet 112, and a plurality of spray holes communicating with the spray channel are formed on the inner side wall of the outer cylinder 11. The plurality of spray holes are arranged at intervals along the circumference of the air outlet 112. When the inner cylinder 12 rotates, the water flow in the outer cylinder 11 can flow through the spray channel and be sprayed onto the filter screen 13 through the plurality of spray holes. Combined with the cleaning component 21 cleaning the filter screen 13, the filter screen 13 is cleaned by both the cleaning component 21 and the spray.

[0114] Example 6

[0115] Based on any of the embodiments 1 to 4, this embodiment proposes to add an eccentric block to the cleaning component 21, and the eccentric block is disposed between the cleaning component 21 and the filter screen 13; when the cleaning component 21 rotates, the eccentric block applies a vibration force to the filter screen 13, which helps to shake off the hair that is stubbornly attached to the holes of the filter screen 13.

[0116] Preferably, the eccentric block is made of plastic.

[0117] Example 7

[0118] Based on any one of the embodiments 1 to 6, this embodiment proposes that the inner sidewall of the outer cylinder 11 is provided with guide ribs on the outer periphery of the air outlet 112 and in the circumferential direction of the outer cylinder 11. The guide ribs can guide the water flow in the outer cylinder 11 to the hydraulic action part when the inner cylinder 12 rotates. The position and structure of the guide ribs satisfy the following: so that the impeller 22 can rotate stably and continuously.

[0119] And / or, such as Fig. 5 Fig. 5 As shown, the outer wall of the inner drum 12 is provided with a water-dispersing rib 121. The water-dispersing rib 121 can deflect the water flow in the outer drum 11 toward the hydraulic action part when the inner drum 12 rotates. During the washing process, the water-dispersing rib 121 helps to drive more water flow in the outer drum 11 to impact the impeller 22, thereby enhancing the cleaning effect. At the same time, it can better clean the area between the inner drum 12 and the outer drum 11, avoiding the growth of bacteria. Specifically, the water-dispersing rib 121 is connected to the inner drum 12 by a snap-fit, and the position of the water-dispersing rib 121 corresponds to the position of the lifting rib on the inner drum 12.

[0120] Furthermore, when the inner wall of the outer cylinder 11 is provided with guide ribs, the position and / or direction of the guide ribs can be adjusted according to the rotation speed of the inner cylinder 12, and / or the position and / or direction of the guide ribs can be adjusted according to the degree of dirtiness of the filter screen 13; so that more water flow in the outer cylinder 11 is accurately and strongly guided to the hydraulic action part, achieving a more comprehensive and thorough cleaning of the filter screen 13;

[0121] When the outer wall of the inner cylinder 12 is provided with water-dispelling ribs 121, the position and / or direction of the water-dispelling ribs 121 can be adjusted according to the rotation speed of the inner cylinder 12, and / or the position and / or direction of the water-dispelling ribs 121 can be adjusted according to the degree of dirtiness of the filter screen 13; so that more water flow in the outer cylinder 11 is accurately and strongly directed to the hydraulic action part, achieving a more comprehensive and thorough cleaning of the filter screen 13.

[0122] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
