Description

Technical Field

[0001] This application relates to the field of washing equipment technology, and in particular to a stirring device and washing equipment. Background Technology

[0002] Agitator washing machines have an agitator inside the washing drum that extends to a certain height. The rotation of the agitator rubs the clothes back and forth, thereby improving the cleaning effect and effectively preventing clothes from getting tangled.

[0003] In related technologies, washing equipment includes a filter inside the drum. During the washing process, lint and other debris carried away from the laundry by the liquid can be filtered and collected by the filter. However, when the water level is lower than the height of the agitator blades, the liquid is difficult to enter the filter under the agitator's drive, affecting the washing effect. Summary of the Invention

[0004] In view of this, embodiments of this application aim to provide a stirring device and a washing device to solve the problem that liquids are difficult to enter the filtration device for filtration.

[0005] To achieve the above objectives, a first aspect of this application provides a stirring apparatus, comprising:

[0006] Agitator wheel;

[0007] A stirring rod is connected to the stirring wheel, and a portion of the stirring rod protrudes radially outward to form blades; the stirring rod has an installation space.

[0008] A filtration device, at least partially disposed within the installation space, includes a housing and a filtration section. The housing has a filtration space inside, which is capable of accommodating at least a portion of the filtration section. The housing also has a liquid passage hole communicating with the filtration space. The filtration section is used to filter at least a portion of the liquid flowing into the filtration space.

[0009] The liquid inlet is connected to the filtration space through the liquid passage. At least part of the liquid inlet is located below the blade along the height direction of the stirring device.

[0010] In one embodiment, at least a portion of the stirring wheel protrudes to form a water-repelling ridge, and at least a portion of the liquid inlet hole is disposed on the water-repelling ridge.

[0011] In one embodiment, at least a portion of the liquid inlet hole is disposed on the stirring rod.

[0012] In one embodiment, at least a portion of the edge of the liquid passage protrudes to form an abutment portion, the abutment portion defining a flow channel between the liquid inlet and the liquid outlet, the liquid inlet and the liquid passage being connected through the flow channel.

[0013] In one embodiment, each of the liquid passage holes is connected to at least two of the liquid inlet holes via the flow guide channel.

[0014] In one embodiment, the outer casing is provided with a flow-blocking portion, which is disposed within the filtration space and connected to the edge of the liquid passage hole. The flow-blocking portion is recessed in a direction away from the liquid passage hole to form a flow-blocking area.

[0015] In one embodiment, along the height direction of the stirring device, the baffle portion at least blocks half of the liquid passage.

[0016] In one embodiment, the projection of the stirring rod along the radial direction onto the outer surface of the housing is such that the projections of all the liquid inlets are located within the projection range of the liquid outlets.

[0017] In one embodiment, the blade extends spirally along the height direction of the stirring rod; the liquid inlet is located near the root of the blade, and at least a portion of the liquid inlet is arranged along the extension direction of the blade.

[0018] In one embodiment, the liquid inlet holes are provided on both sides of the root of the blade.

[0019] In one embodiment, the outer shell includes at least two sub-shells that are joined together circumferentially to enclose and form the filtration space.

[0020] In one embodiment, at least a portion of the bottom of the sub-shell is provided with an overlapping plate, and each of the overlapping plates has at least a partially overlapping area in the height direction of the stirring device.

[0021] In one embodiment, some of the overlapping plates are provided with overlapping grooves, and at least a portion of adjacent overlapping plates can extend into the overlapping grooves.

[0022] In one embodiment, the stirring rod is provided with a first liquid outlet hole communicating with the installation space, and the overlapping plate is provided with a second liquid outlet hole, the second liquid outlet hole communicating with the first liquid outlet hole.

[0023] In one embodiment, the filtration unit includes a filter screen that covers the second liquid outlet hole in the filtration space.

[0024] In one embodiment, along the height direction of the stirring device, the lowest point of the filter section is lower than the highest point of the stirring wheel.

[0025] In one embodiment, the interior of the outer casing is provided with reinforcing ribs, which divide the filtration space into a first subspace and a second subspace, and the filter element is provided in both the first subspace and the second subspace.

[0026] A second aspect of this application provides a washing apparatus, comprising:

[0027] Washing drum;

[0028] The stirring device described in any one of the embodiments of this application is rotatably disposed inside the washing drum.

[0029] The stirring device provided in this application includes a stirring wheel, a stirring rod, and a filtering device. The stirring rod has an installation space, within which at least a portion of the filtering device is housed. The filtering device comprises a filtering space and a housing with a filtering section. The housing has a liquid inlet hole, which communicates with the filtering space. Thus, when the washing drum of the washing equipment rotates, the liquid in the washing drum, carrying lint and other debris, enters the filtering space of the filtering device through the liquid inlet hole and is filtered by the filtering section. The lint and other debris are collected in the filtering section. The liquid filtered by the filtering section can return to the washing drum, circulating continuously during the washing process to continuously filter the liquid in the washing drum. This reduces the content of lint and other debris in the liquid in the washing drum, thereby improving the problem of lint residue on clothes, enhancing washing performance, and improving the user experience.

[0030] In addition, at least some of the liquid inlet holes are located below the blades along the height direction of the stirring device. In this way, when the water level in the stirring device is lower than the blades, the liquid can also enter the filtration space for filtration through the liquid inlet holes located below the blades under the drive of the stirring wheel. This improves the problem that the liquid is difficult to be filtered by the filtration device when the washing equipment is in a low water level state, thereby improving the filtration effect and filtration efficiency.

[0049] This application provides a washing device, which includes a washing drum and an agitator according to any one of the embodiments of this application. The agitator is rotatably disposed inside the washing drum.

[0050] It should be noted that the washing equipment can be an agitator washing machine, a top-loading washing machine, a washer-dryer combo, etc., and there are no restrictions here.

[0051] The washing tub is used to hold laundry items, such as clothes, shoes, and carpets. The top side of the washing tub has an opening through which users can put in or take out laundry items.

[0052] Taking an agitator washing machine as an example, an agitator washing machine may only include a washing drum, in which case the washing drum can hold both wash water and clothes. An agitator washing machine may also include an outer drum, with the washing drum disposed inside the outer drum. The outer drum holds wash water, and the washing drum holds clothes.

[0053] The agitator is rotatably mounted inside the washing drum. It is understood that the agitator rotates when the washing equipment is in the washing state. For example, in some embodiments, the washing equipment includes a motor and a reducer, with the motor shaft driving the agitator to rotate via the reducer to wash the laundry.

[0054] There is no restriction on the direction of rotation of the stirring device. For example, it can rotate clockwise and counterclockwise. Clockwise and counterclockwise rotation are only used to indicate that the two rotation directions are opposite, and do not specifically refer to a particular direction.

[0055] It should be noted that during the washing process, the agitator rotates, while the washing drum may or may not rotate; there is no restriction on this.

[0056] This application provides a stirring device 100. Please refer to [link / reference]. Figures 1 to 7 The stirring device 100 includes a stirring wheel 1, a stirring rod 2, a filter device 3, and a liquid inlet 4. The stirring rod 2 is connected to the stirring wheel 1, and a portion of the stirring rod 2 protrudes radially outward to form blades 24. The stirring rod 2 has an installation space 21. The filter device 3 is at least partially disposed within the installation space 21. The filter device 3 includes a housing 31 and a filter section 32. The housing 31 has a filter space 312 inside, which can at least accommodate a portion of the filter section 32. The housing 31 also has a liquid passage hole 313 communicating with the filter space 312. The filter section 32 is used to filter at least a portion of the liquid flowing into the filter space 312. The liquid inlet 4 communicates with the filter space 312 through the liquid passage hole 313. Along the height direction of the stirring device 100, at least a portion of the liquid inlet 4 is located below the blades 24.

[0057] The stirring device 100 is a device used to mix multiple substances evenly. The stirring function is achieved by rotating components such as the stirring wheel 1 and the stirring rod 2.

[0058] The stirring wheel 1 is one of the core components of the stirring device 100. It is usually driven by a motor to rotate and has various shapes and structures, such as paddle type and turbine type. Through the centrifugal force and shear force generated by high-speed rotation, the stirred material generates strong convection and diffusion in the container, thereby achieving the purpose of uniform mixing.

[0059] The stirring rod 2 is connected to the stirring wheel 1 and plays a role in assisting stirring and transferring liquid. It has an installation space 21 inside, which is used to place the filter device.

[0060] Blade 24 is part of stirring rod 2, and a portion of stirring rod 2 protrudes radially outward to form blade 24. Blade 24 is an important component of stirring device 100 to achieve stirring function. When stirring device 100 is running, stirring rod 2 rotates, driving blade 24 to rotate. Blade 24 causes liquid to flow through interaction with the liquid.

[0061] The filter device 3 is used to separate and remove impurities, particles, etc. from a liquid. The filter device 3 includes a housing 31, a filter section 32, etc., and achieves effective filtration of the liquid through a specific structural design.

[0062] The outer casing 31 serves as the external structure of the filter device 3, protecting the internal components and forming specific flow channels and spaces. The baffle 311 it forms guides the flow of liquid, the filtration space 312 provides a place for the filtration process, and the liquid passage 313 is one of the channels for liquid to enter and exit the filtration space 312. Overall, it ensures the normal operation of the filter device 3 and the realization of the filtration function.

[0063] The shape of the outer casing 31 is not limited here; it can be designed as cylindrical or square, and optimized according to the installation space 21 and the principles of fluid dynamics.

[0064] The filter section 32 is the key part of the filter device 3 that directly realizes the filtration function. It usually uses filter media such as filter screen and filter element 322. Depending on the particle size and properties of the material to be filtered, the appropriate filtration precision and material are selected to effectively intercept impurities in the liquid.

[0065] The specific type of the filter section 32 is not limited here. Besides common filter screens and filter cartridges 322, a multi-layer filtration structure can also be used. For example, a coarse filter screen can be placed at the inlet of the filter section 32 to intercept larger particles of impurities. Then, multiple layers of filter screens or filter media of different precision can be placed inside, such as an activated carbon layer to adsorb odors and small molecule impurities, and an ultrafiltration membrane layer to further remove fine particles and colloidal substances, thereby achieving deep purification of the liquid. A sealing ring or slot-type sealing structure is used between the filter section 32 and the outer shell 31 to ensure that the liquid can only pass through the filter media, preventing unfiltered liquid from leaking through gaps and ensuring the reliability of the filtration effect.

[0066] The liquid passage 313 serves to connect the liquid inlet 4 and the filtration space 312, acting as an intermediate link for the flow of liquid within the stirring device 100. It is a channel that connects the liquid inlet 4 and the filtration space 312, allowing liquid to flow smoothly from the liquid inlet 4 into the filtration space 312, thus acting as an intermediate bridge for liquid transfer.

[0067] The liquid inlet 4 is the channel for liquid to enter the stirring device 100. It is the initial inlet for the liquid to enter the device and provides the liquid to be processed for the entire stirring device 100. The liquid then begins to enter the subsequent processing flow.

[0068] The specific location of the liquid inlet hole 4 is not limited here. For example, the liquid inlet hole 4 can be a hole opened on the stirring rod 2 or a hole opened on the stirring wheel 1. Of course, multiple holes can be opened on both the stirring rod 2 and the stirring wheel 1 as liquid inlet holes 4.

[0069] The height direction of the stirring device 100 is not limited here. For ease of explanation, the height direction of the stirring device 100 is the direction shown in the attached figure.

[0070] When viewed from the bottom to the top of the stirring device 100, at least a portion of the inlet holes 4 are located below the blades 24. Thus, when the water level is below the blades 24 of the stirring rod 2, the blades 24 of the stirring rod 2 cannot interact with the liquid, driving the liquid from the inlet holes 4 into the filtration space 312 for filtration. However, since at least a portion of the inlet holes 4 are located below the blades 24—for example, some inlet holes 4 may be located on the stirring rod 2 or some may be located on the stirring wheel 1 below the stirring rod 2—the force exerted by the stirring wheel 1 on the liquid can drive the liquid from the inlet holes 4 located below the blades 24 into the filtration space 312 for filtration.

[0071] In some embodiments, the washing device is equipped with different water level settings to correspond to different washing scenarios. For example, the washing device includes a single water level mode, a second water level mode, a third water level mode, etc., and the water level increases as the water level increases. Here, "at least some of the liquid inlet holes 4 are located below the blade 24" also includes at least some of the liquid inlet holes 4 being below the single water level and able to be submerged by the water level of the single water level mode.

[0072] The stirring device 100 provided in this embodiment includes a stirring wheel 1, a stirring rod 2, and a filtering device 3. The stirring rod 2 is installed in a space 21, within which at least a portion of the filtering device 3 is housed. The filtering device 3 comprises a filtering space 312 and a housing 31 with a filtering section 32. The housing 31 has a liquid inlet 313, and the liquid inlet 4 communicates with the filtering space 312 through the liquid inlet 313. Thus, when the washing drum of the washing equipment rotates, the liquid in the washing drum can carry lint and other debris through the liquid inlet 4 into the filtering space 312 of the filtering device 3, where it is filtered by the filtering section 32. The lint and other debris are collected in the filtering section 32. The liquid filtered by the filtering section 32 can return to the washing drum, circulating continuously during the washing process to continuously filter the liquid in the washing drum. This reduces the content of lint and other debris in the liquid in the washing drum, thereby improving the problem of lint residue on clothes, enhancing the washing effect, and improving the user experience.

[0073] Furthermore, along the height direction of the stirring device 100, at least part of the liquid inlet hole 4 is located below the blade 24. Thus, when the water level in the stirring device 100 is lower than the blade 24, the liquid can also enter the filtration space 312 for filtration through the liquid inlet hole 4 located below the blade 24 under the drive of the stirring wheel 1. This improves the problem that the liquid is difficult to be filtered by the filtration device 3 when the washing equipment is in a low water level state, thereby improving the filtration effect and filtration efficiency.

[0074] In some embodiments, please refer to Figures 1 to 7 At least a portion of the stirring wheel 1 protrudes to form a water-repelling ridge 11, and at least a portion of the liquid inlet hole 4 is disposed on the water-repelling ridge 11.

[0075] The water-dispelling ridge 11 is a structure formed by a portion of the stirring wheel 1 protruding from it. During the rotation of the stirring wheel 1, the water-dispelling ridge 11 pushes the liquid, changes the flow state of the liquid, and causes the liquid to rotate with the rotation of the stirring wheel 1, thereby changing the flow trajectory of the liquid in the stirring device 100, thus enhancing the stirring effect.

[0076] The specific shape of the water-dispersing ridge 11 is not limited here; for example, it can be elongated, toothed, or wavy. Different shapes of water-dispersing ridges 11 have different effects on the liquid when the stirring wheel 1 rotates. Elongated water-dispersing ridges 11 may create a more stable water flow guiding effect, pushing the liquid in a specific direction; toothed or wavy water-dispersing ridges 11 can generate more turbulence in the liquid, further enhancing the stirring effect.

[0077] The specific location of the liquid inlet 4 is not explicitly defined here. For example, the liquid inlet 4 can be located on both sides of the water-dispelling ridge 11. In this way, when the water-dispelling ridge 11 rotates, the pressure generated by the side of the water-dispelling ridge 11 during its interaction with the liquid can force the liquid into the liquid inlet 4.

[0078] It should be noted that, since the stirring wheel 1 is connected to the stirring rod 2, the stirring wheel 1 and the stirring rod 2 are provided with a channel connecting the liquid inlet hole 4 and the filtration space 312. In this way, the liquid entering from the liquid inlet hole 4 can flow into the filtration space 312 for filtration through this channel.

[0079] By setting the liquid inlet 4 on the water-dispelling ridge 11, the liquid located below the stirring rod 2 can enter the stirring device 100 and, under the driving action of the water-dispelling ridge 11, enter the filtration space 312 through the liquid inlet 4 on the water-dispelling ridge 11 for filtration, thereby improving the filtration efficiency.

[0080] In some embodiments, please refer to Figures 1 to 7 At least part of the liquid inlet hole 4 is provided on the stirring rod 2.

[0081] The distribution of the liquid inlet holes 4 on the stirring rod 2 is not limited here. For example, they can be evenly distributed in a specific area of ​​the stirring rod 2, so that the liquid can enter the stirring device 100 more evenly. Another case is that they are concentrated on one side of the stirring rod 2, such as providing multiple liquid inlet holes 4 on the side of the stirring rod 2 with blades 24, so that the liquid can mix with the liquid in the stirring area more quickly after entering.

[0082] The stirring rod 2 is the core component of the stirring device 100, occupying a certain height along the height of the device. The liquid inlet 4 is located on the stirring rod 2. Firstly, driven by the blades 24 of the stirring rod 2, liquid can flow into the filtration space 312 through the liquid inlet 4 for filtration. Secondly, as the liquid level gradually rises, the liquid surface gradually submerges the stirring rod 2. At this time, the presence of the liquid inlet 4 on the stirring rod 2 increases the number of channels for liquid to enter the flow space, allowing more liquid to enter the flow space for filtration. Furthermore, since the liquid inlet 4 is located on the stirring rod 2, the path of the liquid into the filtration space is shortened, which helps to improve the stirring efficiency.

[0083] In some embodiments, please refer to Figures 1 to 8 At least part of the liquid passage 313 has a protruding edge to form an abutment portion 318. The abutment portion 318 and the liquid inlet 4 define a flow channel 3181, and the liquid inlet 4 and the liquid passage 313 are connected through the flow channel 3181.

[0084] The contact portion 318 is a structure formed by at least a portion of the edge of the liquid passage 313 protruding. The contact portion 318 works together with the liquid inlet 4 to form a specific liquid flow channel, namely the guide channel 3181, which guides and constrains the flow of liquid.

[0085] The shape and size of the contact portion 318 can be designed according to actual needs. For example, the contact portion 318 can be a regular ring formed around the edge of the liquid passage 313, which can uniformly guide and constrain the liquid.

[0086] In some embodiments, at least a portion of the liquid inlet hole 4 is provided on the stirring rod 2, and the outer casing 31 is provided with a liquid passage hole 313 at a corresponding position. A periphery of each liquid passage hole 313 extends towards the liquid inlet hole 4 to form an abutment portion 318. After the filter device 3 and the stirring rod 2 are assembled, the abutment portion 318 abuts against the liquid inlet hole 4 and seals the periphery of the liquid inlet hole 4. A flow channel 3181 is defined between the abutment portion 318 and the liquid inlet hole 4, so that liquid entering from the liquid inlet hole 4 is guided by the flow channel 3181 and enters the filter space 312 from the liquid passage hole 313. The abutment and sealing effect of the abutment portion 318 improves the efficiency of liquid entering the filter space 312.

[0087] In some embodiments, each liquid passage 313 is provided with a corresponding abutment portion 318, which abuts against the corresponding liquid inlet 4. The abutment portions 318 can be connected to form a whole to form a grid structure, with each grid opening corresponding to one liquid passage 313.

[0088] In some embodiments, at least a portion of the liquid inlet 4 is disposed on the water-repelling ridge 11, and the water-repelling ridge 11 has a flow-guiding cavity inside. Liquid entering from the liquid inlet 4 flows along the flow-guiding cavity to the filter device 3. The housing 31 is provided with a liquid passage 313, the edge of which extends toward the flow-guiding cavity. When assembled, the flow-guiding cavity communicates with the flow-guiding channel 3181, thereby communicating the liquid inlet 4 with the liquid passage 313. The formed flow-guiding channel 3181 can guide the liquid entering from the liquid inlet 4 on the water-repelling ridge 11 into the filter space 312.

[0089] In some embodiments, at least some of the liquid inlet holes 4 are disposed on the stirring rod 2, and at least some of the liquid inlet holes 4 are disposed on the water-repelling ridge 11. In this case, there are various ways to arrange the flow channel 3181. One flow channel 3181 can correspond to one type of inlet hole 4. For example, some flow channels 3181 correspond to the inlet holes 4 on the stirring rod 2, while others correspond to the inlet holes 4 on the water-repelling ridge 11. Alternatively, one flow channel 3181 can correspond to inlet holes 4 at different locations. For example, some flow channels 3181 extend to both the inlet holes 4 on the stirring rod 2 and the inlet holes 4 on the water-repelling ridge 11. In this way, the inlet holes 4 on the stirring rod 2 and the inlet holes 4 on the water-repelling ridge 11 can be connected to the same liquid passage hole 313 and enter the filtration space 312 from the same liquid passage hole 313. Of course, each flow channel 3181 can also correspond to only one inlet hole 4, that is, each inlet hole 4 is connected to a liquid passage hole 313 through a flow channel 3181, forming independent channels.

[0090] The design of the flow channel 3181 makes the flow path of the liquid from the inlet hole 4 to the outlet hole 313 clearer and more stable. It prevents disordered flow and backflow of the liquid between the inlet hole 4 and the outlet hole 313, ensuring that the liquid smoothly enters the filtration space 312 along the designed path, thus improving the efficiency and stability of liquid transfer. The presence of the contact part 318 enhances the sealing between the inlet hole 4 and the outlet hole 313 to a certain extent. Because the contact part 318 and the inlet hole 4 tightly cooperate to form the flow channel 3181, the possibility of liquid leakage is reduced, lowering the risk of corrosion or damage to other components of the device due to liquid leakage, thereby improving the overall durability and reliability of the stirring device 100.

[0091] In some embodiments, please refer to Figure 2 Each liquid passage 313 is connected to at least two liquid inlet holes 4 through a flow guide channel 3181.

[0092] Each liquid passage 313 is not connected to only one liquid inlet 4, but is connected to at least two liquid inlet 4 through a flow channel 3181. This means that liquid entering from multiple liquid inlet 4 can be gathered into the same liquid passage 313 through their respective corresponding flow channels 3181, and then flow into the filtration space 312.

[0093] Multiple liquid inlet holes 4 are connected to a liquid outlet hole 313, which is equivalent to increasing the number of inlets for liquid to enter the filtration space 312, enabling more liquid to enter the filtration space 312 per unit time, improving the liquid entry efficiency, and thus speeding up the working process of the entire stirring device 100.

[0094] In some embodiments, to prevent large particles from entering the filtration space 312 and causing blockage, which would adversely affect the filtration effect, the cross-sectional area of ​​the liquid inlet 4 is reduced, and multiple liquid inlets 4 are provided corresponding to one liquid outlet 313. In this way, the liquid inlets 4 can perform preliminary screening of the liquid about to enter the filtration space 312, so that only target filter materials such as hair can enter the filtration space 312 for further filtration, thereby effectively reducing the entry of large particulate impurities into the filtration device 3 and ensuring the smooth and efficient operation of the filtration process.

[0095] Each liquid passage 313 has a corresponding liquid inlet 4, ensuring smooth liquid transfer from the stirring rod 2 to the filter device 3 and preventing liquid blockage or backflow caused by mismatched liquid passages. Because the liquid can enter the corresponding liquid passage 313 evenly from each liquid inlet 4, and thus be evenly distributed within the filtration space 312, all areas of the filter section 32 can fully contact the liquid to be filtered, avoiding localized over- or under-filtration.

[0096] In some embodiments, please refer to Figures 1 to 7 The outer casing 31 is provided with a flow-blocking part 311, which is disposed in the filter space 312 and connected to the edge of the liquid passage 313. The flow-blocking part 311 is recessed in the direction away from the liquid passage 313 to form a flow-blocking area 3111.

[0097] In some embodiments, the flow-blocking part 311 can be designed as a curved sheet structure with a certain curvature, or it can be designed as an ellipse or rectangle, etc., to adapt to different liquid flow requirements and the shielding design of the flow-blocking part 311. The edges of the orifice can be chamfered to reduce resistance to liquid flow, and a smooth coating, such as a Teflon coating, can be applied to the inner wall of the orifice to further reduce the friction between the liquid and the orifice wall, improving the liquid flow efficiency. Furthermore, a reinforcing rib can be provided around the liquid passage orifice 313 to enhance the structural strength of this area to withstand the pressure generated by the installation of the flow-blocking part 311 and the liquid flow.

[0098] The baffle 311 blocks the top area of ​​the liquid passage 313, preventing liquid from entering directly from the top. Instead, the liquid is guided by the baffle 311 and enters the filter device 3 from the unblocked bottom area of ​​the liquid passage 313, thus fulfilling the requirement of the baffle 311 to guide some liquid to the bottom of the filter device. Furthermore, the baffle 311 blocks the top area of ​​the liquid passage 313, meaning that when the stirring rod 2 rotates, the liquid entering the filtration space 312 flows along the side wall of the filtration space 312 under centrifugal force, preventing it from flowing out from the blocked top area of ​​the liquid passage 313. This reduces the amount of unfiltered liquid directly discharged from the liquid passage 313 within the filtration space 312, thereby improving the filtration effect and efficiency.

[0099] It should be noted that some liquid may flow out from the bottom area of ​​the liquid passage 313 that is not blocked by the flow-blocking part 311. However, since the cross-sectional area of ​​the liquid inlet end of the liquid passage 313 is larger than the area of ​​the bottom area of ​​the liquid passage 313 that is not blocked by the flow-blocking part 311, the amount of liquid entering the filtration space 312 through the liquid passage 313 is greater than the amount of liquid thrown out of the filtration space 312 due to centrifugal force. Thus, during the rotation process, the liquid in the liquid passage 313 always flows into the filtration space 312.

[0100] The flow-blocking area 3111 is formed by the recess of the flow-blocking part 311 and has a specific shape. Its function is to guide the liquid flowing in from the liquid passage 313 to smoothly enter the filtration space, while blocking the liquid in the filtration space from flowing out of the liquid passage.

[0101] The concave shape of the baffle 311 can be designed in various forms. For example, a parabolic concave shape can be used, which allows the liquid to gradually change its flow direction and accelerate after entering the baffle region 3111, forming a more uniform flow velocity distribution. This is suitable for filtration scenarios that require high liquid flow velocity and large flow rates. Alternatively, it can be designed as a smooth concave shape with a certain curvature, such as a semi-circular concave shape. This shape allows the liquid to change its flow direction smoothly within the baffle region 3111, reducing the generation of turbulence. This is more suitable for some fine filtration processes that require high liquid flow stability.

[0102] The edges of the liquid passage 313 can be specially treated, such as being ground into rounded corners or chamfered. This can reduce local turbulence and energy loss caused by sharp edges when the liquid flows in, allowing the liquid to enter the baffle area 3111 more smoothly. An elastic sealing material, such as a rubber sealing ring, can also be set around the edge of the liquid passage. When the baffle 311 is connected to the liquid passage 313, it can further enhance the sealing of the connection, ensuring that all incoming liquid can be effectively guided by the baffle 311, avoiding liquid leakage and affecting the filtration effect.

[0103] The flow-blocking part 311 is disposed inside the filtration space 312 of the filter device 3, and one end of it is tightly connected to the edge of the liquid passage 313. The shape of the flow-blocking part 311 is not flat, but recessed in the direction away from the liquid passage 313, thereby constructing a specific space for guiding the liquid flow, namely the flow-blocking region 3111. When liquid flows in from the liquid passage 313, it will first enter this flow-blocking region 3111. Due to the special shape and spatial constraints of the flow-blocking region 3111, the flow direction of the liquid will be changed. Instead of rushing directly into the filtration space 312 in a disordered manner, the liquid will flow towards the bottom of the filter device 3 according to the path set by the flow-blocking region 3111.

[0104] The recessed design of the baffle portion 311 forms a baffle area 3111 that can precisely guide the liquid flow, making the liquid flow path within the filtration space 312 more rational. Furthermore, besides shielding the area above the liquid passage 313, the baffle portion 311 protrudes within the filtration space 312. This guides the liquid within the filtration space 312 to flow away from the liquid passage 313 as it flows along the side wall of the filtration space 312 under centrifugal force, further reducing the amount of liquid flowing out of the liquid passage 313 and thus improving the filtration effect and efficiency.

[0105] Through experiments, with the washing equipment at a medium water level, 1g of thread was added to the washing equipment, and the weight of collected lint was compared. Without the baffle 311, the average collection rate of the filter device was 86%. With the baffle 311 installed, the average collection rate of the filter device was 95%. It is evident that the baffle 311 improves the removal rate of impurities, thereby enhancing the overall filtration efficiency.

[0106] In some embodiments, please refer to Figures 1 to 7 Along the height direction of the stirring device 100, the baffle 311 at least blocks half of the liquid passage 313.

[0107] The flow-blocking portion 311 covers at least half of the top area of ​​the liquid passage 313 in the vertical direction. When liquid enters the filter device 3 from the outside through the liquid passage 313, its flow path is significantly affected by the flow-blocking portion 311. Most or all of the liquid will enter the filtration space 312 along the direction guided by the flow-blocking portion 311, that is, it will flow freely from the unblocked part of the liquid passage 313. This achieves top-down guidance of the liquid flow into the filter device 3, resulting in better filtration effect and equipment performance.

[0108] Furthermore, the baffle 311 is located within the filtration space 312, blocking the upper half of the liquid passage 313. This design not only ensures that liquid entering the liquid passage 313 can only flow in from the unblocked area below, thus guiding the liquid to flow from top to bottom, but also, during the operation of the stirring device 100, when the liquid in the filtration space 312 is thrown towards the liquid passage 313 by centrifugal force, the baffle 311 blocks at least half of the area of ​​the liquid passage 313, that is, the cross-sectional area of ​​the blocked part is greater than or equal to half of the total area of ​​the liquid passage 313. Therefore, it can effectively block liquids that attempt to escape from the liquid passage 313 out of the filtration space 312, ensuring that as much liquid as possible completes the filtration process within the filtration space 312.

[0109] In this context, the obstruction ratio of the flow-blocking part 311 on the liquid passage 313 can vary, ranging from exactly half to more than half. It should be noted that the smaller the area obstructed by the flow-blocking part 311, the greater the volume of liquid escaping from the filtration space 312; conversely, the larger the area obstructed by the flow-blocking part 311, the greater the resistance encountered by the liquid entering the liquid passage 313. In practical applications, various factors need to be considered comprehensively, such as the properties of the liquid, flow rate, filtration requirements, and the operating parameters of the stirring device 100, to rationally determine the obstruction range of the flow-blocking part 311. This ensures both effective filtration and smooth liquid flow, enabling the entire stirring and filtration device 3 to operate efficiently and stably.

[0110] In some embodiments, please refer to Figure 2 The projection of the stirring rod 2 onto the outer surface of the outer shell 31 is along the radial direction, and the projection of all the liquid inlet holes 4 is located within the projection range of the liquid outlet holes 313.

[0111] When observed radially from the stirring rod 2, and the inlet hole 4 on the stirring rod 2 is projected onto the outer surface of the housing 31, all projection points fall within the area covered by the projection of the through hole 313. This indicates that, spatially, the inlet hole 4 and the through hole 313 exhibit a specific nested structure along the radial direction; specifically, along the radial direction of the stirring rod 2, the inlet hole 4 is nested within the through hole 313. This design allows the liquid flowing in from the inlet hole 4 to pass through the through hole 313 to the maximum extent possible in the subsequent filtration process, thereby improving filtration efficiency and quality and ensuring that more liquid is effectively filtered.

[0112] In its design, the inlet hole 4 and the outlet hole 313 should be as close as possible to each other. This is to minimize the possibility of leakage through the gap between them during the transfer of liquid from the inlet hole 4 to the outlet hole 313. Ideally, the inlet hole 4 and the outlet hole 313 should fit together tightly without any gaps, thus completely eliminating the risk of leakage. However, considering the convenience of actual assembly operations, a certain gap is permissible between the inlet hole 4 and the outlet hole 313, but this gap should be controlled to be less than 2mm. This design satisfies the convenience requirements of the assembly process while keeping the leakage during liquid transfer to an acceptable low level, thereby ensuring the overall performance of the equipment while also meeting the practical operational needs of the manufacturing process.

[0113] In some embodiments, please refer to Figures 1 to 7 The blade 24 extends spirally along the height direction of the stirring rod 2, and the liquid inlet 4 is located near the root of the blade 24, and at least some of the liquid inlet 4 are arranged along the extension direction of the blade 24.

[0114] The stirring rod 2 has blades 24 formed in a radially outward protrusion in a portion of its area. These blades 24 extend in a spiral shape along the height direction of the stirring rod 2. This design allows the stirring rod 2 to more effectively drive the liquid flow and mix when it rotates.

[0115] The blade 24 can be designed with a twisted shape with a certain curvature, rather than just a simple planar spiral. This twisted blade 24 generates a more complex flow field when rotating, inducing not only vertical and radial liquid flow but also circumferential vortex flow, further enhancing the mixing effect and energy transfer efficiency. Simultaneously, the surface of the blade 24 can be specially textured, such as by engraving tiny grooves or protrusions. These microstructures increase the turbulence of the liquid as it flows over the surface of the blade 24, promoting the diffusion and mixing of substances in the liquid and improving the stirring quality.

[0116] The blade 24 can be detachably connected to the main body of the stirring rod 2, for example, by means of a slot and bolts. This allows for easy replacement of blades 24 with different shapes, sizes, and materials according to different stirring tasks and liquid characteristics, improving the flexibility and versatility of the stirring device 100. Furthermore, a flexible rubber sealing material can be provided around the edge of the blade 24. When the blade 24 is mounted on the stirring rod 2, the sealing material can tightly adhere to the surface of the stirring rod 2, preventing liquid leakage from the connection between the blade 24 and the stirring rod 2, ensuring the sealing and stability of the stirring process.

[0117] Meanwhile, the liquid inlet 4 is located near the root of the blade 24. When the stirring rod 2 rotates, the blade 24 promotes liquid flow, and the root of the blade 24 experiences relatively high liquid pressure during the rotation of the stirring rod 2. Positioning the liquid inlet 4 at this location helps the liquid to be forced into it more efficiently, thereby improving filtration efficiency.

[0118] Furthermore, some of the liquid inlet holes 4 are arranged along the extension direction of the blades 24. In this way, regardless of the liquid level, it can be ensured that some of the liquid inlet holes 4 are submerged in the liquid, thereby expanding the applicability of the stirring device 100 in filtration operation and enabling it to maintain good filtration performance and operational stability under different liquid level conditions.

[0119] In some embodiments, "the liquid inlet hole 4 is close to the root of the blade 24" means that when multiple blades extend along parallel and identical extension lines, the midline of the two contour lines of two adjacent blades 24 extending along the extension lines, and the area defined by the contour lines of the blade 24, is the range of the root position of the blade.

[0120] An experiment was conducted by adding 1g of thread to the washing equipment and comparing the collected lint weight. When the washing equipment was at a low water level, filter device 3 collected 65% of the lint when unloaded and 21% when half-loaded. At a high water level, filter device 3 collected 96% of the lint when unloaded and 48% when half-loaded.

[0121] As can be seen, some of the liquid inlet holes 4 are arranged along the extension direction of the blade 24 at both high and low water levels, and the filter device 3 can perform filtration.

[0122] The spirally extending blades 24 on the stirring rod 2 generate strong vertical and circumferential flow fields when rotating, causing the liquid to form a complex circulating flow within the stirring container. This enhances the shear force and turbulence of the liquid, thereby improving the uniformity and efficiency of the stirring. The design of the liquid inlet holes 4, located close to the root of the blades 24 and partially arranged along the extension direction of the blades 24, allows the liquid to enter and exit the stirring rod 2 more efficiently through the liquid inlet holes 4 under the influence of the flow field generated by the rotation of the blades 24.

[0123] In some embodiments, please refer to Figure 1 Liquid inlet holes 4 are provided on both sides of the root of the blade 24.

[0124] Liquid inlet holes 4 are provided on both sides of the root of the blade 24. In this way, regardless of whether the stirring rod 2 rotates clockwise or counterclockwise, there is a liquid inlet hole 4 at the maximum pressure area formed at the root of the blade 24. This broadens the applicability of the stirring device 100, enabling it to operate efficiently under different rotation directions. It ensures that the liquid exchange and stirring effect are not affected by the rotation direction, maintaining stable and good working performance.

[0125] In some embodiments, please refer to Figure 6 The outer shell 31 includes at least two sub-shells 314, which are spliced ​​together along the circumference of the outer shell 31 to form a filter space 312.

[0126] Subshells 314 are components of the outer shell 31. They are multiple independent units divided from the original one-piece outer shell 31. These subshells 314 have their own shapes and structural features. They are combined together in a specific splicing method to form a complete outer shell 31 structure, thereby enclosing the filter space 312.

[0127] The sub-shell 314 can be designed in various shapes, such as arc-shaped plates or polygonal plates, to adapt to different shape and structural requirements of the filter device 3. For example, for a circular filter device 3, the sub-shell 314 can be designed as a fan-shaped plate with a certain curvature, and multiple fan-shaped sub-shells 314 can be spliced ​​together to form a complete circular outer shell 31; for a square or rectangular filter device 3, the sub-shell 314 can be designed as a rectangular plate, forming a closed space through splicing around the perimeter. The edges of the sub-shell 314 can be designed with tenons and mortises, slots, or threads for connection, facilitating quick and accurate splicing between sub-shells 314 while ensuring the sealing and structural strength after splicing.

[0128] The material of the sub-shell 314 can be selected according to the filtration environment and requirements. For example, for filtration of corrosive liquids, corrosion-resistant stainless steel, plastics (such as polytetrafluoroethylene), or ceramics can be used; for filtration in high-temperature environments, high-temperature resistant alloy materials or special ceramic materials can be selected. In addition, the internal surface of the sub-shell 314 can be specially treated, such as by coating a smooth layer (such as Teflon coating) to reduce the adhesion of liquid to the inner wall of the sub-shell 314 and the flow resistance, thereby improving the filtration efficiency; or by setting some micro-flow guiding structures, such as tiny grooves or protrusions, to guide the flow direction of liquid in the filtration space 312 and optimize the filtration effect.

[0129] The splicing between sub-shells 314 can be achieved using various connection methods, such as welding, bolting, snap-fitting, or sealant bonding. Welding provides high connection strength and sealing, making it suitable for filter devices 3 with high requirements for structural strength and sealing. However, this connection method is relatively fixed and not conducive to subsequent disassembly and maintenance. Bolted connections offer removability, facilitating the replacement of sub-shells 314 or internal maintenance of the filter device 3. However, attention must be paid to the sealing of the bolts to prevent liquid leakage. Snap-fitting connections are simple and quick to operate, enabling rapid assembly and disassembly, and are suitable for occasions requiring frequent replacement of filter components 32 or equipment cleaning. Sealant bonding forms a sealing layer at the splicing points of sub-shells 314, effectively preventing liquid leakage and also providing some buffering and shock absorption, making it suitable for filter systems with extremely high sealing requirements and low vibration.

[0130] In some embodiments, the outer shell 31 is not a single integral component, but rather consists of at least two sub-shells 314. These sub-shells 314 are spliced ​​together along the circumference of the outer shell 31 and tightly joined together using a suitable connection method, ultimately forming a space for accommodating the filter media and performing liquid filtration operations, namely, the filtration space 312. This design makes the manufacturing and assembly of the outer shell 31 more flexible, and also facilitates the maintenance and repair of the interior of the filter device 3, as well as the adjustment of the size and shape of the filtration space 312 according to actual needs, providing possibilities for the optimization and diversified application of the entire filter device 3.

[0131] In some embodiments, please refer to Figure 6 At least a portion of the bottom of the subshell 314 is provided with an overlapping plate 3141, and each overlapping plate 3141 has at least a partially overlapping area in the height direction of the stirring device 100.

[0132] The overlapping plate 3141 is a plate-like structure disposed at the bottom of at least part of the sub-shell 314. Its main function is to cooperate with the overlapping plates 3141 on other sub-shells 314 to form an overlapping area in the height direction of the stirring device 100, thereby achieving a tighter and more stable connection between the sub-shells 314. At the same time, it enhances the sealing and structural strength of the entire outer shell 31 in the bottom area, prevents liquid from leaking from the splicing gaps at the bottom of the sub-shells 314, causing gap jamming / lint leakage, and ensuring the normal operation and filtration effect of the filter device 3.

[0133] The overlapping plate 3141 can be designed in various shapes, such as rectangular, trapezoidal, or dovetail, to adapt to different sub-shell 314 shapes and splicing requirements. For example, for a circular sub-shell 314, the overlapping plate 3141 can be designed as an arc-shaped fan plate. When multiple fan-shaped overlapping plates 3141 are spliced ​​at the bottom, they can better fit the circular outline and improve the tightness of the connection. For a square sub-shell 314, a rectangular overlapping plate 3141 is more suitable. Its edges can be chamfered or rounded to reduce stress concentration and facilitate splicing operations.

[0134] The thickness of the overlap plate 3141 can be selected according to the size of the filter device 3, the pressure it bears, and the requirements for sealing. Generally speaking, for larger filter devices 3 or those subjected to higher pressure, a thicker overlap plate 3141 needs to be selected to ensure sufficient structural strength and sealing performance.

[0135] The surface of the overlap plate 3141 can be specially treated, such as by setting anti-slip textures or protrusions on the overlap surface. When multiple overlap plates 3141 overlap each other, these anti-slip textures or protrusions can increase friction and prevent the overlap plates 3141 from sliding relative to each other during use, thereby further improving the stability of the connection.

[0136] At least a portion of the sub-shells 314 have overlapping plates 3141 installed at their bottoms. When these sub-shells 314 are assembled, the overlapping plates 3141 at the bottom of each sub-shell 314 will partially overlap each other in the vertical direction of the stirring device 100. This overlapping design ensures that the connection between the sub-shells 314 relies not only on the edge splicing but also increases the connection area and stability through the overlap of the bottom overlapping plates 3141. This improves the overall integrity and sealing of the entire outer shell 31 structure, and is particularly important in withstanding liquid pressure and preventing leakage, thus ensuring the reliable operation of the filtration device 3.

[0137] In some embodiments, please refer to Figures 6 to 7 The overlapping plate 3141 is provided with an overlapping groove 31411, and at least a portion of the adjacent overlapping plate 3141 can extend into the overlapping groove 31411.

[0138] The overlap groove 31411 is a groove structure located on a portion of the overlap plate 3141. Its shape and size are adapted to the edge of the adjacent overlap plate 3141 to accommodate at least a portion of the adjacent overlap plate 3141. Through this nested design, the tightness of the connection and positioning accuracy between the overlap plates 3141 are further improved, and the reliability and stability of the connection between the sub-shells 314 are enhanced, thereby optimizing the structural performance of the entire filter device 3 housing 31.

[0139] The shape and size of the overlapping plate 3141 can be designed in various ways according to the size and shape of the sub-shell 314. For example, for a circular sub-shell 314, the overlapping plate 3141 can be designed as an arc, and its width and thickness are determined according to the pressure borne by the filter device 3 and the requirements for sealing. The overlapping groove 31411 can be set on one side edge of the arc-shaped overlapping plate 3141. The depth and width of the groove match the thickness of the adjacent overlapping plate 3141 and the size of the insertion part. The inner wall of the groove can be polished to reduce the friction during insertion. At the same time, some small protrusions or grooves can be set at the bottom of the groove to increase the friction between the overlapping plate 3141 and the insertion plate, preventing it from accidentally coming out during use.

[0140] For square or rectangular subshells 314, the overlapping plate 3141 can be designed as a rectangular plate, and the overlapping groove 31411 can be located at one end or both sides of the plate. The shape of the overlapping groove 31411 can be rectangular, trapezoidal, or dovetail, etc., and different shapes of overlapping grooves 31411 have different connection characteristics.

[0141] Some of the overlapping plates 3141 have specific grooves machined into them, namely overlapping grooves 31411. When adjacent sub-shells 314 are spliced, a portion of the corresponding overlapping plate 3141 can be inserted into this overlapping groove 31411, forming a nested connection similar to mortise and tenon joints. This design makes the connection between the overlapping plates 3141 more than just a simple planar overlap. Instead, through the cooperation of the groove and the plate, the contact area and friction of the connection are increased, improving the firmness and stability of the connection. This, in turn, enhances the structural strength and sealing of the entire filter device 3 housing 31, ensuring that the filter device 3 can better withstand liquid pressure and prevent leakage during operation.

[0142] In some embodiments, please refer to Figures 1 to 7 The stirring rod 2 is provided with a first liquid outlet 23 that communicates with the installation space 21, and the overlapping plate 3141 is provided with a second liquid outlet 31412 that communicates with the first liquid outlet 23.

[0143] The first liquid outlet 23 is a channel structure located on the stirring rod 2. It is one of the channels for the exchange and flow of liquid between the inside of the stirring rod 2 and the outside. It is connected to the installation space 21, so that the liquid can flow in an orderly manner between the inside of the stirring rod 2, the installation space 21 and subsequent connecting parts (such as the second liquid outlet 31412 on the overlapping plate 3141).

[0144] The second liquid outlet 31412 is a channel structure set on the overlapping plate 3141, located at the bottom of the filtration space 312. It is connected to the first liquid outlet 23 on the stirring rod 2. Its main function is to guide the liquid filtered in the filtration space 312 to the first liquid outlet 23 and flow out from the first liquid outlet 23.

[0145] The diameter of the first liquid outlet 23 can be designed to be adjustable, for example, by using an elastic material to make the hole wall and changing the hole size through an external pressure device or electromagnetic control mechanism.

[0146] The shape of the second liquid outlet 31412 can be designed as an ellipse or a rectangle to adapt to the shape of the overlapping plate 3141 and the direction of liquid flow, so as to improve the liquid throughput efficiency.

[0147] On the inner wall of the second liquid outlet 31412, some tiny guide protrusions or grooves can be provided. These microstructures can guide the liquid to form a specific flow direction when it flows out of the second liquid outlet 31412, so that it can better integrate with the liquid flow field inside the filter device 3, and avoid turbulence or excessive local flow velocity caused by improper liquid outflow direction, which would affect the filtration effect.

[0148] The installation space 21 inside the stirring rod 2 communicates with the outside through the first liquid outlet 23, and the second liquid outlet 31412 on the overlapping plate 3141 is connected to the first liquid outlet 23. This forms a liquid channel from the inside of the stirring rod 2 through the first liquid outlet 23 and then through the second liquid outlet 31412 to the other side of the overlapping plate 3141. When the stirring rod 2 rotates and stirs the liquid, the liquid inside can flow smoothly out of the filter device through this channel. In this way, the liquid being filtered in the filtration space 312 can be continuously discharged from the filtration space 312 to accommodate newly entering liquid for filtration. This cycle ensures that the entire stirring and filtering device 3 can operate efficiently and stably.

[0149] In some embodiments, along the height direction of the stirring device 100, the lowest point of the filter section 32 is lower than the highest point of the stirring wheel 1.

[0150] By setting the lowest point of the filter section 32 to be lower than the highest point of the stirring wheel 1, the liquid entering from the stirring wheel 1 can also be filtered in the filter section 32 after entering the filter space 312 when the water level is low, and the liquid that settles or flows down after stirring can also be filtered, thereby improving the filtration efficiency and treatment effect.

[0151] In some embodiments, please refer to Figure 5 The filter section 32 includes a filter screen 321, which covers the second liquid outlet hole 31412 in the filter space 312.

[0152] Filter mesh 321 is a mesh material with a specific pore size or pore structure. It can intercept and separate solid particles and impurities in a liquid based on the pore size, allowing qualified liquids to pass through, thereby achieving the purpose of liquid purification. Factors such as the material, pore size, porosity, and shape and structure of filter mesh 321 all affect its filtration performance. Different filtration needs require different types of filter mesh 321 to ensure optimal filtration results.

[0153] The filter device 3 is equipped with a filter screen 321, which is positioned in the filtration space 312 to cover the second liquid outlet 31412. In this way, the liquid that has been filtered in the filtration space 312 can undergo a final filtration process by passing through the filter screen 321 before flowing out through the second liquid outlet 31412, thereby further improving the overall filtration effect and ensuring that the outflowing liquid reaches a higher purity standard, meeting more stringent usage or subsequent processing requirements.

[0154] In some embodiments, please refer to Figure 5 The filter section 32 includes a filter element 322, which is disposed within the filter space 312.

[0155] Filter element 322 is a key component in the filtration unit 32 that enables filtration. It typically possesses specific structural and material properties. Made from materials with filtration properties, such as filter paper, filter screens, membrane materials, and fiber materials, these materials are processed using special techniques to form the filter element 322 body with a specific pore structure. This structure allows for selective retention of impurities in the liquid based on pore size and surface characteristics, while allowing compliant liquids to pass through, thus achieving filtration. The material, pore size distribution, filtration accuracy, dust holding capacity, and service life of filter element 322 are important indicators of its performance. Different application scenarios require the selection of different types of filter elements 322 to meet specific filtration needs.

[0156] The filter element 322 can be designed in various forms to adapt to different filtration needs and operating conditions. For example, for high-precision filtration requirements, a multi-layer composite filter element 322 structure can be used. This could involve an internal ultrafiltration membrane with a fine microporous structure to intercept tiny particles and colloidal substances, and an outer pre-filtration layer with a larger pore size to initially remove larger particulate impurities. This multi-layer structure ensures high filtration accuracy while extending the lifespan of the filter element 322 and preventing the microporous membrane from being rapidly clogged by large particles. Furthermore, the shape of the filter element 322 can also be diversified. In addition to the common cylindrical filter element 322, a pleated filter element 322 can be designed. This increases the filtration area to improve filtration efficiency while reducing the volume of the filter element 322, making it suitable for filtration devices with limited space.

[0157] The interior of the filtration space 312 can be equipped with a dedicated filter element 322 fixing structure, such as a slot, bracket, or clamp, to ensure that the filter element 322 is stably positioned within the filtration space 312 and will not be displaced or damaged due to the impact or vibration of liquid flow. These fixing structures can be designed to be detachable for easy installation and replacement of the filter element 322.

[0158] The main filtration element of the filtration section 32 is the filter element 322, which is placed in the filtration space 312 of the filtration device 3. This means that when the liquid enters the filtration space 312, it will come into direct contact with the filter element 322. The filter element 322, with its own filtration characteristics, such as specific pore size, porosity and adsorption performance, intercepts and removes impurities in the liquid, thus purifying the liquid that passes through the filter element 322.

[0159] In some embodiments, please refer to Figure 6 The interior of the outer shell 31 is provided with a reinforcing rib 315, which divides the filter space 312 into a first subspace 316 and a second subspace 317. Both the first subspace 316 and the second subspace 317 are provided with filter elements 322.

[0160] In some embodiments, the filter element 322 has a mesh structure, and the outer shell 31 has perforated areas where no liquid passage holes 313 are provided, with the filter element 322 covering the perforated areas. After the liquid enters the filtration space 321, the water level in the filtration space 321 drops under the action of centrifugal force. Some of the liquid moves away from the center of rotation under the action of centrifugal force, passes through the filter element 322, and flows out of the filtration space 321, leaving the lint in the liquid in the filtration space. In some embodiments, the liquid can also pass through the filter screen 321 from the bottom and be discharged from the second liquid outlet 31412.

[0161] The reinforcing rib 315 is a plate-like structure installed inside the outer shell 31. Its main purpose is to enhance the structural strength and stability of the outer shell 31 and prevent the outer shell 31 from deforming or being damaged when subjected to liquid pressure, vibration or other external forces.

[0162] By rationally arranging the reinforcing ribs 315, external forces can be effectively dispersed, the load-bearing capacity of the outer shell 31 can be improved, and the filter device 3 can be operated normally in a relatively harsh working environment. At the same time, the reinforcing ribs 315 also have the function of separating the filter space 312, which has an important impact on the flow path of the liquid and the filtration process.

[0163] The reinforcing rib 315 can be designed in various shapes, such as straight plates, curved plates, and corrugated plates, to adapt to the structural requirements of different shaped shells 31 and filter spaces 312, and to meet different mechanical performance requirements.

[0164] Reinforcing ribs 315 can be arranged along the edges or diagonals of the outer shell 31 to increase its bending and compressive strength. The thickness and height of the reinforcing ribs 315 can also be adjusted according to the size of the outer shell 31, the pressure it bears, and the requirements for structural strength. Generally speaking, for larger filter devices 3 or those subjected to higher pressure, thicker and taller reinforcing ribs 315 need to be selected to ensure sufficient structural stability.

[0165] The first subspace 316 and the second subspace 317 are two relatively independent areas divided by the reinforcing ribs 315 from the filtration space 312. Each of them has a certain spatial range and geometry. Filter elements 322 are set in these two subspaces respectively, so that the filtration process can be carried out simultaneously in different areas. The filtration conditions (such as flow rate, flow velocity, filtration accuracy, etc.) of each subspace can be independently adjusted and optimized as needed, thereby improving the flexibility and adaptability of the entire filtration device 3 and meeting different filtration needs and process requirements.

[0166] The outer casing 31 incorporates reinforcing ribs 315, which divide the originally single filtration space 312 into two parts: a first sub-space 316 and a second sub-space 317. Filter elements 322 are installed in both sub-spaces. When liquid enters the filtration device 3, it flows into the first sub-space 316 and the second sub-space 317 respectively, contacting the corresponding filter element 322 within each sub-space. After filtration by the filter element 322, the liquid flows out from its respective outlet or merges with the filter element before exiting. This design, through the rational division of the filtration space 312 and the distribution of the filter elements 322, enables multi-zone, multi-level filtration operations within the same filtration device 3, improving filtration efficiency and flexibility. It better meets complex filtration needs and different working conditions, optimizing the overall filtration process's effectiveness and stability.

[0167] In some embodiments, please refer to Figures 1 to 7 The filter device 3 includes a decorative part 33, which is disposed at the end of the housing 31 away from the stirring wheel 1. The decorative part 33 is connected to the housing 31. A first snap-fit ​​part 331 is provided on the decorative part 33. A second snap-fit ​​part 22 is provided at the end of the stirring rod 2 away from the stirring wheel 1. The first snap-fit ​​part 331 can snap-fit ​​with the second snap-fit ​​part 22.

[0168] As a component of the filter device 3, the decorative element 33 not only enhances the aesthetic appearance of the equipment, making it more ergonomic and aesthetically pleasing, and increasing the product's market competitiveness, but also may, to some extent, protect the outer casing 31, conceal the internal structure, or connect other components. The material, shape, and color of the decorative element 33 can be customized according to different application scenarios and user needs to achieve an organic combination of functionality and aesthetics.

[0169] The first snap-fit ​​part 331 and the second snap-fit ​​part 22 are specific structural components respectively provided on the decorative part 33 and the stirring rod 2. Their design purpose is to achieve a quick and convenient connection between the decorative part 33 and the stirring rod 2 through their snap-fit ​​engagement, while ensuring the stability and reliability of the connection. The shape, size, and structural form of the snap-fit ​​part can be varied, such as slots and blocks, buckles and eyelets, elastic rings and slots, etc., selected and optimized according to specific application needs and design requirements to meet different assembly and usage conditions.

[0170] The specific structures of the first snap-fit ​​part 331 and the second snap-fit ​​part 22 can be designed in various innovative ways to improve the stability and reliability of the snap-fit ​​while facilitating operation.

[0171] For example, the first snap-fit ​​part 331 can be designed as a flexible snap hook structure with a snap groove inside, while the second snap-fit ​​part 22 can be designed as a protrusion that matches the snap groove. When the protrusion is inserted into the snap groove, the snap hook will tightly hold the protrusion under the elastic action to achieve a firm snap-fit; or the first snap-fit ​​part 331 can be designed as an annular elastic snap ring, and the second snap-fit ​​part 22 can be designed as a cylinder with an annular groove. By fitting the snap ring onto the groove of the cylinder, a fast and stable snap-fit ​​can be achieved.

[0172] In addition, to prevent misoperation or accidental disengagement during the snap-fit ​​process, auxiliary structures such as positioning pins, anti-disengagement clips, or locking devices can be installed on the snap-fit ​​parts. For example, a positioning pin can be installed on one side of the snap-fit ​​part. When the two snap-fit ​​parts are snapped together, the positioning pin will insert into the corresponding positioning hole, ensuring the accuracy and stability of the snap-fit. An anti-disengagement clip, such as a rotatable clip, can be installed at the connection point of the snap-fit ​​parts. After the snap-fit ​​is completed, it can be rotated to the locked position to prevent the snap-fit ​​parts from accidentally disengaging, thereby improving the safety and reliability of the equipment.

[0173] The filter device 3 is equipped with a decorative piece 33, which is installed on the end of the housing 31 away from the stirring wheel 1 and is fixed to the housing 31 by a certain connection method. The decorative piece 33 has a first snap-fit ​​portion 331, while the stirring rod 2 has a second snap-fit ​​portion 22 at its end away from the stirring wheel 1. These two snap-fit ​​portions cooperate to achieve a snap-fit ​​connection between the decorative piece 33 and the stirring rod 2. This design not only functionally links the stirring rod 2 and the filter device 3, but also structurally achieves a specific connection method through the decorative piece 33. This ensures the relative positional stability of the stirring rod 2 and the filter device 3, simplifies the assembly process to some extent, and enhances the overall appearance of the device, satisfying the user's dual needs in terms of function and aesthetics.
