[0054] The rotation direction of the stirring device is not limited. For example, it can rotate forward and reverse. Forward rotation and reverse rotation are only to indicate that the rotation directions of the two are opposite, and do not specify a certain direction.

[0055] It should be noted that during the washing process, the stirring device rotates, and the washing drum can rotate or not rotate, which is not limited herein.

[0056] Embodiments of the present application provide a stirring device 100, please refer to Figures 1 to 7 The stirring device 100 includes a stirring wheel 1, a stirring rod 2, a filtering device 3 and a liquid inlet hole 4. The stirring rod 2 is connected with the stirring wheel 1, part of the stirring rod 2 projects radially outward to form a blade 24, and the stirring rod 2 has a mounting space 21. The filtering device 3 is at least partially arranged in the mounting space 21, and the filtering device 3 includes an outer shell 31 and a filtering part 32. The inner part of the outer shell 31 has a filtering space 312, which can at least contain part of the filtering part 32. The outer shell 31 is also provided with a liquid passing hole 313 communicating with the filtering space 312, and the filtering part 32 is at least used to filter at least part of the liquid flowing into the filtering space 312. The liquid inlet hole 4 communicates with the filtering space 312 through the liquid passing hole 313, and at least part of the liquid inlet hole 4 is located below the blade 24 in the height direction of the stirring device 100.

[0057] The stirring device 100 is a device for uniformly mixing a plurality of substances, and the stirring function is realized by the rotation of the stirring wheel 1, the stirring rod 2 and other components.

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

[0059] The stirring rod 2 is connected with the stirring wheel 1 and plays a role in assisting stirring and transmitting liquid. The stirring rod 2 is internally provided with an installation space 21 for placing the filtering device.

[0060] The blade 24 is a part of the stirring rod 2, and a part of the stirring rod 2 protrudes radially outward to form the blade 24. The blade 24 is an important component for the stirring device 100 to realize the stirring function. When the stirring device 100 operates, the stirring rod 2 rotates to drive the blade 24 to rotate. The blade 24 makes the liquid flow through the interaction with the liquid.

[0061] The filtering device 3 is used for separating and removing impurities and particles in the liquid. The filtering device 3 includes an outer shell 31, a filtering part 32, etc., and realizes effective filtering of the liquid through specific structural design.

[0062] The outer shell 31 serves as the external structure of the filtering device 3 and plays a role in protecting the internal components and forming specific flow channels and spaces. The flow blocking part 311 formed by the outer shell 31 can guide the flow direction of the liquid, the filtering space 312 provides a place for the filtering process, and the liquid passage 313 is one of the channels for the liquid to enter and exit the filtering space 312, which ensures the normal operation of the filtering device 3 and the realization of the filtering function.

[0063] The shape of the outer shell 31 is not limited here and can be designed as a cylindrical shape or a square shape, which is optimized according to the installation space 21 and the principle of fluid mechanics.

[0064] The filtering part 32 is a key part of the filtering device 3 that directly realizes the filtering function. Usually, filter screens, filter cores 322, etc. are used as filtering media. According to the particle size and properties of the filtered substances, appropriate filtering precision and materials are selected to effectively intercept impurities in the liquid.

[0065] The specific type of the filtering part 32 is not limited here. In addition to the common filter screens and filter cores 322, a multi-layer filtering structure can also be used, such as a layer of coarse filter screen at the inlet of the filtering part 32 to intercept larger particles, and then multiple layers of filter screens or filtering media with different precision inside, such as an activated carbon layer for adsorbing odors and small molecular impurities, and an ultrafiltration membrane layer for further removing small particles and colloidal substances, so as to realize deep purification of the liquid. A sealing rubber ring or a clamping groove type sealing structure is used between the filtering part 32 and the outer shell 31 to ensure that the liquid can only pass through the filtering media for filtering, prevent the unfiltered liquid from leaking from the gap, and ensure the reliability of the filtering effect.

[0066] The liquid passing hole 313 serves to connect the liquid inlet hole 4 and the filtering space 312, and is an intermediate link for the liquid to flow inside the stirring device 100. It is a channel that connects the liquid inlet hole 4 and the filtering space 312, so that the liquid can flow smoothly from the liquid inlet hole 4 into the filtering space 312, and is an intermediate bridge for the liquid transmission.

[0067] The liquid inlet hole 4 is a channel for the liquid to enter the stirring device 100, and is the entrance for the liquid to enter the device initially, providing a source of liquid to be processed for the entire stirring device 100, and the liquid begins to enter the subsequent processing process from here.

[0068] The specific position of the liquid inlet hole 4 is not limited here, for example, the liquid inlet hole 4 can be a hole on the stirring rod 2, or a hole on the stirring wheel 1, of course, multiple holes on the stirring rod 2 and the stirring wheel 1 can also be used as the liquid inlet hole 4.

[0069] The height direction of the stirring device 100 is not limited here, and here the height direction of the stirring device 100 is the direction shown in the drawing for convenience of explanation.

[0070] When viewed from the bottom to the top of the stirring device 100, at least a part of the liquid inlet hole 4 is below the blade 24. In this way, when the water level is lower than the blade 24 of the stirring rod 2, the blade 24 of the stirring rod 2 cannot interact with the liquid to drive the liquid to enter the filtering space 312 from the liquid inlet hole 4 for filtering. However, since at least a part of the liquid inlet hole 4 is below the blade 24, for example, part of the liquid inlet hole 4 can be provided on the stirring rod 2 or part of the liquid inlet hole 4 can be provided on the stirring wheel 1 below the stirring rod 2, and due to the force of the stirring wheel 1 on the liquid, the liquid can be driven to enter the filtering space 312 from the liquid inlet hole 4 below the blade 24 for filtering.

[0071] In some embodiments, the washing device is provided with a mode of different water level gears to correspond to different washing scenes. For example, the washing device includes a first gear water level mode, a second gear water level mode, a third gear water level mode, etc., and the water level increases with the increase of the gear. Here, "at least a part of the liquid inlet hole 4 is below the blade 24" also includes that at least part of the liquid inlet hole 4 is below the first gear water level, which can be submerged by the water level of the first gear water level mode.

[0072] The stirring device 100 provided by the embodiment of the present application comprises a stirring wheel 1, a stirring rod 2 and a filtering device 3. The stirring rod 2 is provided with a mounting space 21, and at least part of the filtering device 3 is arranged in the mounting space 21. The filtering device 3 is provided with a filtering space 312 and a shell 31 with a filtering part 32. The shell 31 is provided with a liquid inlet hole 313. The liquid inlet hole 4 is in communication with the filtering space 312 through the liquid inlet hole 313. Thus, when the washing drum of the washing equipment rotates, the liquid in the washing drum can carry the lint and other impurities into the filtering space 312 of the filtering device 3 through the liquid inlet hole 4, and the lint and other impurities can be filtered by the filtering part 32 and collected in the filtering part 32. The liquid filtered by the filtering part 32 can return to the washing drum, and the process is repeated in the washing process, so that the liquid in the washing drum is continuously filtered, thereby reducing the content of the lint and other impurities in the liquid in the washing drum, improving the problem of lint remaining on the clothes, and improving the washing effect and user experience.

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

[0074] In some embodiments, referring to Figures 1 to 7 , at least part of the area of the stirring wheel 1 protrudes to form a water-repellent ridge 11, and at least part of the liquid inlet hole 4 is arranged on the water-repellent ridge 11.

[0075] The water-repellent ridge 11 is a structure formed by the protrusion of part of the area of the stirring wheel 1. During the rotation of the stirring wheel 1, the water-repellent ridge 11 can push the liquid to change the flow state of the liquid, drive the liquid to rotate with the rotation of the stirring wheel 1, and further change the flow trajectory of the liquid in the stirring device 100, so as to enhance the stirring effect.

[0076] The specific shape of the water-repellent ridge 11 is not limited here, which can be, for example, a strip shape, a tooth shape or a wave shape, etc. The water-repellent ridges 11 with different shapes have different effects on the liquid when the stirring wheel 1 rotates. The water-repellent ridge 11 with a strip shape can form a relatively stable water flow guiding effect to push the liquid in a specific direction; the water-repellent ridges 11 with a tooth shape or a wave shape can make the liquid produce more turbulent flow, further enhancing the stirring effect.

[0077] The specific position of the liquid inlet hole 4 is not limited here. For example, the liquid inlet hole 4 can be arranged on both sides of the water ridge 11. In this way, when the water ridge 11 rotates, the pressure generated by the side of the water ridge 11 during interaction with the liquid can press the liquid into the liquid inlet hole 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 internally provided with a channel communicating the liquid inlet hole 4 and the filtering space 312. In this way, the liquid entering from the liquid inlet hole 4 can flow into the filtering space 312 through the channel for filtering.

[0079] Arranging the liquid inlet hole 4 on the water ridge 11 can make the liquid located below the stirring rod 2 enter the stirring device 100 and, under the driving action of the water ridge 11, enter the filtering space 312 through the liquid inlet hole 4 on the water ridge 11 for filtering, thereby improving the filtering efficiency.

[0080] In some embodiments, referring to Figures 1 to 7 , at least part of the liquid inlet hole 4 is arranged on the stirring rod 2.

[0081] The distribution form of the liquid inlet hole 4 on the stirring rod 2 is not limited here. For example, it can be uniformly 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 to be concentrated on one side of the stirring rod 2, such as arranging multiple liquid inlet holes 4 on the side of the stirring rod 2 with blades 24, so that the liquid can be mixed 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 that undertakes the stirring function and occupies a certain space height in the height direction of the stirring device 100. Arranging the liquid inlet hole 4 on the stirring rod 2 can, on the one hand, enable the liquid to flow from the liquid inlet hole 4 on the stirring rod 2 into the filtering space 312 for filtering under the driving action of the blades 24 of the stirring rod 2. On the other hand, as the liquid level gradually rises, the liquid surface will gradually submerge the stirring rod 2. At this time, arranging the liquid inlet hole 4 on the stirring rod 2 can increase the number of channels for the liquid to enter the filtering space, so that more liquid can enter the filtering space from the liquid inlet hole 4 for filtering. In addition, since the liquid inlet hole 4 is arranged on the stirring rod 2, the path of the liquid entering the filtering space is shortened, which is conducive to improving the stirring efficiency.

[0083] In some embodiments, referring to Figures 1 to 8 , at least part of the edge of the liquid passing hole 313 is protruded to form an abutting portion 318, and the abutting portion 318 and the liquid inlet hole 4 define a flow guide channel 3181, and the liquid inlet hole 4 and the liquid passing hole 313 are communicated through the flow guide channel 3181.

[0084] The abutting portion 318 is a structure protruding from the edge of the liquid passing hole 313. The abutting portion 318 cooperates with the liquid inlet hole 4 to form a specific liquid flow channel, i.e., a guide flow channel 3181, which guides and restricts the flow of liquid.

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

[0086] In some embodiments, at least part of the liquid inlet hole 4 is arranged on the stirring rod 2, and the shell 31 is provided with a liquid passing hole 313 at the corresponding position. The edge of each liquid passing hole 313 extends in the direction close to the liquid inlet hole 4 to form an abutting portion 318. After the filter device 3 is assembled with the stirring rod 2, the abutting portion 318 abuts against the liquid inlet hole 4 and seals the edge of the liquid inlet hole 4. The abutting portion 318 and the liquid inlet hole 4 define a guide flow channel 3181, so that the liquid entering from the liquid inlet hole 4 enters the filter space 312 from the liquid passing hole 313 under the guidance of the guide flow channel 3181. The abutting and sealing effect of the abutting portion 318 improves the efficiency of the liquid entering the filter space 312.

[0087] In some embodiments, each liquid passing hole 313 is provided with a corresponding abutting portion 318 to abut against the corresponding liquid inlet hole 4. Each abutting portion 318 can be connected to form an integral whole to form a grid structure, and each grid opening corresponds to a liquid passing hole 313.

[0088] In some embodiments, at least part of the liquid inlet hole 4 is arranged on the water repellent ridge 11, and the water repellent ridge 11 has a guide cavity inside. The liquid entering from the liquid inlet hole 4 flows along the guide cavity to the filter device 3. The shell 31 is provided with a liquid passing hole 313, and the edge of the liquid passing hole 313 extends in the direction close to the guide cavity. After assembly, the guide cavity communicates with the guide flow channel 3181, so that the liquid inlet hole 4 communicates with the liquid passing hole 313. The formed guide flow channel 3181 can guide the liquid entering from the liquid inlet hole 4 on the water repellent ridge 11 into the filter space 312.

[0089] In some embodiments, at least part of the liquid inlet hole 4 is arranged on the stirring rod 2, and at least part of the liquid inlet hole 4 is arranged on the water-removing ridge 11. At this time, the arrangement of the flow guide channel 3181 has multiple modes. One flow guide channel 3181 can correspond to one position of the liquid inlet hole 4, for example, some flow guide channels 3181 correspond to the liquid inlet holes 4 on the stirring rod 2, and the other flow guide channels 3181 correspond to the liquid inlet holes 4 on the water-removing ridge 11; or one flow guide channel 3181 can correspond to liquid inlet holes 4 at different positions, for example, some flow guide channels 3181 extend to both the liquid inlet holes 4 on the stirring rod 2 and the liquid inlet holes 4 on the water-removing ridge 11, so that the liquid inlet holes 4 on the stirring rod 2 and the liquid inlet holes 4 on the water-removing ridge 11 can be in communication with the same liquid passage 313 and enter the filtering space 312 from the same liquid passage 313; of course, each flow guide channel 3181 can also correspond to only one liquid inlet hole 4, that is, each liquid inlet hole 4 is in communication with one liquid passage 313 through one flow guide channel 3181, forming an independent channel.

[0090] The arrangement of the flow guide channel 3181 makes the flow path of the liquid from the liquid inlet hole 4 to the liquid passage 313 more clear and stable. It can avoid the disorderly flow and backflow of the liquid between the liquid inlet hole 4 and the liquid passage 313, ensure that the liquid can smoothly enter the filtering space 312 according to the designed path, and improve the efficiency and stability of the liquid transmission. The existence of the abutment part 318 can enhance the sealing between the liquid inlet hole 4 and the liquid passage 313 to some extent. Since the abutment part 318 closely cooperates with the liquid inlet hole 4 to form the flow guide channel 3181, the possibility of liquid leakage is reduced, and the risk of corrosion or damage to other parts of the device caused by liquid leakage is reduced, thereby improving the overall durability and reliability of the stirring device 100.

[0091] In some embodiments, referring to Figure 2 each liquid passage 313 is in communication with at least two liquid inlet holes 4 through the flow guide channel 3181.

[0092] Each liquid passage 313 is not connected to only one liquid inlet hole 4, but establishes a communication relationship with at least two liquid inlet holes 4 through the flow guide channel 3181. This means that the liquid entering from multiple liquid inlet holes 4 can converge into the same liquid passage 313 through the respective flow guide channels 3181, and then flow into the filtering space 312.

[0093] The communication of multiple liquid inlet holes 4 with one liquid passage 313 is equivalent to increasing the number of entrances for the liquid to enter the filtering space 312, which can make more liquid enter the filtering space 312 in unit time, improve the entering efficiency of the liquid, and thus speed up the working process of the entire stirring device 100.

[0094] In some embodiments, in order to prevent large particles from entering the filtering space 312 and causing blockage, thereby adversely affecting the filtering effect, the cross-sectional area of the liquid inlet hole 4 is reduced, and multiple liquid inlet holes 4 are arranged corresponding to one liquid passing hole 313. In this way, the liquid inlet hole 4 can perform preliminary screening on the liquid about to enter the filtering space 312, so that only the target filtering material such as fluff can enter the filtering space 312 for further filtering, thereby effectively reducing the entry of large-particle impurities into the filtering device 3, and ensuring the smooth and efficient progress of the filtering process.

[0095] Each liquid passing hole 313 has a corresponding liquid inlet hole 4, which ensures smooth transmission of liquid from the stirring rod 2 to the filtering device 3, and avoids liquid blockage or backflow caused by mismatching of the liquid passing hole. Since the liquid can uniformly enter the corresponding liquid passing hole 313 from each liquid inlet hole 4, and then be uniformly distributed in the filtering space 312, the liquid to be filtered can fully contact each area of the filtering part 32, avoiding local over-filtering or under-filtering.

[0096] In some embodiments, referring to Figures 1 to 7 , the shell 31 is provided with a flow blocking part 311, which is arranged in the filtering space 312 and connected to the edge of the liquid passing hole 313. The flow blocking part 311 is recessed in the direction away from the liquid passing hole 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 as an oval or rectangular shape, to adapt to different liquid flow requirements and the shielding design of the flow blocking part 311. The edge of the hole can be chamfered to reduce the resistance of liquid flow, and a smooth coating such as a Teflon coating can be applied to the inner wall of the hole to further reduce the friction between the liquid and the hole wall, thereby improving the passing efficiency of the liquid. In addition, a reinforcing rib can be arranged around the liquid passing hole 313 to enhance the structural strength of this area to withstand the pressure caused by the installation of the flow blocking part 311 and the liquid flow.

[0098] The flow blocking part 311 blocks the top area of the liquid passing hole 313, so that the liquid cannot directly enter from the top, but enters the filtering device 3 from the bottom of the liquid passing hole 313 along the guidance of the flow blocking part 311, to meet the requirement of the flow blocking part 311 to direct part of the liquid to the bottom of the filtering device. In addition, the flow blocking part 311 blocks the top area of the liquid passing hole 313, that is, when the stirring rod 2 rotates, the liquid entering the filtering space 312 flows on the side wall of the filtering space 312 under the action of centrifugal force, and the liquid cannot flow out from the top blocked area of the liquid passing hole 313, thereby reducing the amount of unfiltered liquid in the filtering space 312 directly discharged from the liquid passing hole 313, and improving the filtering effect and efficiency.

[0099] Here, it should be noted that there can be a part of the liquid flowing out from the bottom area of the liquid passing hole 313 which is not shielded by the flow blocking part 311. But since the cross-sectional area of the liquid inlet end of the liquid passing hole 313 is larger than the area of the bottom area of the liquid passing hole 313 which is not shielded by the flow blocking part 311, the amount of liquid entering the filtering space 312 through the liquid passing hole 313 is larger than the amount of liquid being thrown out from the filtering space 312 due to the centrifugal force, so during the rotation process, the liquid in the liquid passing hole 313 is always flowing towards the inside of the filtering space 312.

[0100] The flow blocking area 3111 is a specific shape formed by the concave of the flow blocking part 311, which functions to guide the liquid flowing in from the liquid passing hole 313 to smoothly enter the filtering space, while blocking the liquid in the filtering space from flowing out from the liquid passing hole.

[0101] The concave shape of the flow blocking part 311 can be designed in multiple forms, for example, a concave similar to a parabola, which can make the liquid gradually change direction and accelerate after entering the flow blocking area 3111, forming a relatively uniform flow velocity distribution, suitable for filtering scenarios with high liquid flow velocity requirements and large flow rate; or a smooth concave with a certain arc, such as a semicircular concave, which can make the liquid change direction smoothly in the flow blocking area 3111, reducing the generation of turbulence, suitable for some fine filtering processes with high requirements for liquid flow stability.

[0102] The edge of the liquid passing hole 313 can be specially treated, such as being polished into a rounded or chamfered corner, which can reduce the local turbulence and energy loss caused by the sharp edge when the liquid flows in, making the liquid enter the flow blocking area 3111 more smoothly; a ring of elastic sealing material, such as a rubber sealing ring, can also be provided on the edge of the liquid passing hole, which can further enhance the sealing of the connection between the flow blocking part 311 and the liquid passing hole 313, ensuring that all the incoming liquid can be effectively guided by the flow blocking part 311, avoiding liquid leakage and affecting the filtering effect.

[0103] The flow blocking part 311 is placed inside the filtering space 312 of the filtering device 3, and one end thereof is closely connected to the edge of the liquid passing hole 313. The shape of the flow blocking part 311 is not flat, but is concave towards the direction away from the liquid passing hole 313, thereby constituting a specific space for guiding the flow direction of the liquid, i.e. the flow blocking area 3111. When the liquid flows in from the liquid passing hole 313, it will first enter this flow blocking area 3111, and due to the special shape and space constraints of the flow blocking area 3111, the flow direction of the liquid will be changed, no longer directly rushing towards the inside of the filtering space 312 in disorder, but flowing according to the path set by the flow blocking area 3111 towards the bottom of the filtering device 3.

[0104] The recessed design of the flow blocking part 311 forms a flow blocking area 3111 which can accurately guide the flow direction of the liquid, making the flow path of the liquid in the filtering space 312 more reasonable. In addition, the flow blocking part 311 is convex in the filtering space 312, in addition to playing a shielding role on the upper area of the liquid passing hole 313. Thus, when the liquid in the filtering space 312 flows on the side wall of the filtering space 312 under the action of centrifugal force, it can be guided to flow away from the liquid passing hole 313, which is beneficial to further reduce the amount of liquid flowing out of the liquid passing hole 313, and thus improve the filtering effect and filtering efficiency.

[0105] Through experiments, 1g of thread ends were added to the washing equipment under the condition that the washing equipment was at the medium water level, and the weight of the collected lint was tested for comparison experiments. Without the flow blocking part 311, the average collection rate of the filtering device was 86%. With the flow blocking part 311, the average collection rate of the filtering device was 95%. It can be seen that the setting of the flow blocking part 311 can improve the removal rate of impurities, thereby improving the overall filtering efficiency.

[0106] In some embodiments, referring to Figures 1 to 7 , along the height direction of the stirring device 100, the flow blocking part 311 at least blocks half of the liquid passing hole 313.

[0107] The flow blocking part 311 covers at least half of the area of the top region of the liquid passing hole 313 in the vertical direction. When the liquid enters the filtering device 3 from the outside through the liquid passing hole 313, its flow path will be significantly affected by the flow blocking part 311, and most or all of the liquid will enter the filtering space 312 along the direction guided by the flow blocking part 311, i.e. from the unblocked part of the liquid passing hole 313, thereby realizing the downward guidance of the flow direction of the liquid entering the filtering device 3, so as to achieve better filtering effect and device performance.

[0108] In addition, the flow blocking part 311 is located in the filtering space 312 and blocks the upper half of the liquid passing hole 313. This design not only makes the liquid entering the liquid passing hole 313 flow from the unblocked area below, thereby guiding the liquid to flow from top to bottom, but also effectively blocks the liquid that tries to escape from the filtering space 312 through the liquid passing hole 313 when the liquid in the filtering space 312 is thrown towards the liquid passing hole 313 under the action of centrifugal force during the operation of the stirring device 100, because the flow blocking part 311 blocks at least half of the area of the liquid passing hole 313, i.e. the blocked part has a cross-sectional area greater than or equal to half of the total area of the liquid passing hole 313, thereby ensuring that as much liquid as possible completes the filtering process in the filtering space 312.

[0109] In this context, the shielding ratio of the flow blocking part 311 to the liquid passing hole 313 has multiple possibilities, which can shield exactly half of the area or more than half of the area. It should be noted that the smaller the area shielded by the flow blocking part 311, the more the volume of liquid escaping in the filtering space 312 is relatively more; on the contrary, the larger the area shielded by the flow blocking part 311, the greater the resistance the liquid receives when entering the liquid passing hole 313. In actual application, various factors need to be considered, such as the nature of the liquid, the flow, the filtering requirements and the operating parameters of the stirring device 100, etc., so as to reasonably determine the shielding range of the flow blocking part 311, so as to ensure the filtering effect while taking into account the smooth inflow of the liquid, so that the whole stirring and filtering device 3 can run efficiently and stably.

[0110] In some embodiments, referring to Figure 2 , the projections of all the liquid inlet holes 4 on the outer surface of the shell 31 are located within the projection range of the liquid passing hole 313 along the radial direction of the stirring rod 2.

[0111] When observing from the radial direction of the stirring rod 2 and projecting the liquid inlet hole 4 on the stirring rod 2 onto the outer surface of the shell 31, all the projection points fall within the area range covered by the projection of the liquid passing hole 313. This shows that in the spatial position, the liquid inlet hole 4 and the liquid passing hole 313 present a specific nested structure relationship along the radial direction, specifically, along the radial direction of the stirring rod 2, the liquid inlet hole 4 is in a nested state by the liquid passing hole 313. Through such design, the liquid flowing from the liquid inlet hole 4 can be maximized to enter the subsequent filtering process through the liquid passing hole 313, thereby improving the efficiency and quality of filtering and ensuring that more liquid is effectively filtered.

[0112] In design, the liquid inlet hole 4 and the liquid passing hole 313 should be as close to each other as possible, the purpose of which is to minimize the possibility of leakage of liquid from the gap between the two during the transfer process from the liquid inlet hole 4 to the liquid passing hole 313. Ideally, the liquid inlet hole 4 and the liquid passing hole 313 can be tightly fitted without any gap between them, so as to completely eliminate the risk of liquid leakage from the gap between them. However, considering the convenience requirement of actual assembly operation, a certain gap can be allowed between the liquid inlet hole 4 and the liquid passing hole 313, but the size of this gap should be controlled within the range of less than 2mm. Such design can not only meet the convenience requirement of the assembly process, but also control the leakage amount of the liquid during the transfer process to an acceptable low level, so as to ensure the overall performance of the equipment while taking into account the actual operation requirement in the production process.

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

[0114] The stirring rod 2 is formed with blades 24 in a radially outwardly convex manner in some of its regions, which extend helically along the height direction of the stirring rod 2, so that the stirring rod 2 can more effectively push the liquid to flow and mix when rotating.

[0115] The shape of the blades 24 can be designed to have a certain curvature and a twisted shape, rather than just a simple planar helical shape. Such twisted blades 24 can generate a more complex flow field when rotating, not only having a height direction and a radial liquid flow, but also inducing a circumferential vortex flow, further enhancing the mixing effect and energy transfer efficiency of the liquid. At the same time, the surface of the blade 24 can be specially textured, such as engraved with micro grooves or protrusions, which can increase the degree of turbulence of the liquid when flowing over the surface of the blade 24, promote the diffusion and mixing of substances in the liquid, and improve the stirring quality.

[0116] The blades 24 can be connected to the main body of the stirring rod 2 in a detachable manner, such as through a clamping groove and a bolt, so that different shapes, sizes and materials of the blades 24 can be replaced according to different stirring tasks and liquid properties, improving the flexibility and versatility of the stirring device 100. In addition, a circle of flexible rubber sealing material can be provided on the edge of the blade 24, which can tightly fit the surface of the stirring rod 2 when the blade 24 is installed on the stirring rod 2, preventing liquid from leaking from the connection between the blade 24 and the stirring rod 2, and ensuring the sealing and stability of the stirring process.

[0117] At the same time, the liquid inlet hole 4 is arranged near the root of the blade 24. When the stirring rod 2 rotates, the blade 24 promotes the flow of liquid, and the root of the blade 24 bears a relatively large liquid pressure during the rotation of the stirring rod 2. The liquid inlet hole 4 is arranged at this position, which helps the liquid to be pressed into it more efficiently, thereby improving the filtering efficiency.

[0118] Moreover, some of the liquid inlet holes 4 are arranged along the extension direction of the blade 24. In this way, no matter what the liquid level is, there will be a liquid inlet hole 4 immersed in the liquid, thereby expanding the application range of the stirring device 100 for filtering operation, so that it can maintain good filtering performance and working stability under different liquid level conditions.

[0119] In some embodiments, "the liquid inlet hole 4 is near the root of the blade 24" means that when a plurality of blades extend along parallel and identical extension lines, the midline of the two profile lines along which the adjacent two blades 24 extend is within the range of the root position of the blade 24 defined by the profile line of the blade 24.

[0120] By experiment, 1g of thread is added to the washing device, and the weight of the collected lint is tested for comparison. When the washing device is in a low water level state, the collection of lint by the filter device 3 is 65% when empty and 21% when half loaded. When the water level is high, the collection of lint by the filter device 3 is 96% when empty and 48% when half loaded.

[0121] It can be seen that the partial liquid inlet holes 4 arranged along the extension direction of the blades 24 can filter at low and high water levels.

[0122] The helically extending blades 24 on the stirring rod 2 can generate strong height direction and circumferential flow fields when rotating, forming complex circulating flow in the stirring container, enhancing the shear force and turbulence degree of the liquid, thereby improving the uniformity and efficiency of stirring. The design of the liquid inlet holes 4 near the roots of the blades 24 and partially arranged along the extension direction of the blades 24 allows the liquid to pass in and out of the stirring rod 2 more efficiently under the action of the flow field generated by the rotation of the blades 24.

[0123] In some embodiments, referring to Figure 1 , the roots of the blades 24 are provided with liquid inlet holes 4 on both sides.

[0124] The roots of the blades 24 are provided with liquid inlet holes 4 on both sides, so that whether the stirring rod 2 rotates clockwise or counterclockwise, there are liquid inlet holes 4 at the maximum pressure area formed at the roots of the blades 24, thereby widening the application range of the stirring device 100, enabling it to operate efficiently under different rotating directions, ensuring that the liquid exchange and stirring effect are not affected by the rotating direction, maintaining stable and good working performance.

[0125] In some embodiments, referring to Figure 6 , the shell 31 includes at least two sub-shells 314, and the at least two sub-shells 314 are spliced along the circumference of the shell 31 to form the filtering space 312.

[0126] The sub-shell 314 is a component part of the shell 31, which divides the originally integrated shell 31 into multiple independent units. These sub-shells 314 have their own shape and structural characteristics, and are combined together through a specific splicing method to form a complete shell 31 structure, thereby enclosing the filtering space 312.

[0127] The shape of the sub-shell 314 can be designed in various forms, such as arc-shaped plate, polygonal plate, etc., to adapt to different filtering device 3 shapes and structural requirements. For example, for a circular filtering device 3, the sub-shell 314 can be designed as a fan-shaped plate with a certain arc, and multiple fan-shaped sub-shells 314 are spliced to form a complete circular shell 31; for a square or rectangular filtering device 3, the sub-shell 314 can be designed as a rectangular plate, and the four edges are spliced to form a closed space. The edges of the sub-shell 314 can be designed with connecting structures such as tenon and mortise, clamping slot or thread, etc., to facilitate quick and accurate splicing between the sub-shells 314, while ensuring the sealing performance and structural strength after splicing.

[0128] The material of the sub-shell 314 can be selected according to the filtering environment and requirements. For example, for the filtration of corrosive liquid, materials such as stainless steel, plastic (such as polytetrafluoroethylene) or ceramic can be used; for high-temperature environment, high-temperature resistant alloy materials or special ceramic materials can be selected. In addition, the inner surface of the sub-shell 314 can be treated in a special way, such as coated with a smooth coating (such as Teflon coating) to reduce the adhesion and flow resistance of the liquid on the inner wall of the sub-shell 314, and improve the filtration efficiency; or some micro flow guiding structures such as micro grooves or protrusions can be set to guide the flow direction of the liquid in the filtering space 312, and optimize the filtration effect.

[0129] The splicing between the sub-shells 314 can adopt various connection methods, such as welding, bolt connection, buckle connection or sealant connection, etc. Welding connection can provide high connection strength and sealing performance, and is suitable for filtering devices 3 with high requirements on structural strength and sealing performance, but this connection method is relatively fixed and not conducive to subsequent disassembly and maintenance; bolt connection has the characteristics of disassembly, which is convenient for replacing the sub-shell 314 or maintaining the inside of the filtering device 3, but attention should be paid to the sealing treatment of the bolt to prevent liquid leakage; buckle connection is simple and fast to operate, and can realize quick assembly and disassembly, which is suitable for some occasions that require frequent replacement of the filtering part 32 or cleaning of the equipment; the sealant connection can form a sealing layer at the splicing place of the sub-shell 314, effectively preventing liquid leakage, and also having the effect of buffering and shock absorption, which is suitable for filtering systems with high sealing requirements and small vibration.

[0130] In some embodiments, the shell 31 is not a monolithic component, but is composed of at least two sub-shells 314 which are spliced along the circumferential direction of the shell 31 and tightly combined together through appropriate connecting means to finally enclose a space for accommodating the filter medium and performing liquid filtration operation, i.e. the filtration space 312. This design makes the manufacturing and assembly of the shell 31 more flexible, and also facilitates the maintenance, repair and adjustment of the size and shape of the filtration space 312 according to actual needs, providing the possibility for optimization and diversified application of the entire filtration device 3.

[0131] In some embodiments, referring to Figure 6 , the bottom of at least part of the sub-shells 314 is provided with a lap plate 3141, and each lap plate 3141 has at least a part of the lap overlap region in the height direction of the stirring device 100.

[0132] The lap plate 3141 is a plate-shaped structure arranged at the bottom of at least part of the sub-shells 314, which mainly cooperates with the lap plate 3141 on the other sub-shells 314 to form a lap overlap region in the height direction of the stirring device 100, so as to realize a more stable connection between the sub-shells 314, and at the same time, to enhance the sealing performance and structural strength of the entire shell 31 at the bottom region, prevent liquid from leaking from the joint gap at the bottom of the sub-shells 314, cause the joint gap to be blocked / leak the dust, and ensure the normal operation and filtration effect of the filtration device 3.

[0133] The shape of the lap plate 3141 can be designed in various forms, such as rectangular, trapezoidal or dovetail-shaped, etc., to adapt to different shapes and splicing requirements of the sub-shells 314. For example, for circular sub-shells 314, the lap plate 3141 can be designed as an arc-shaped sector plate, and multiple sector lap plates 3141 can better fit the circular profile when spliced at the bottom, improving the tightness of the connection; for square sub-shells 314, rectangular lap plates 3141 are more suitable, and the edges thereof can be provided with chamfers or rounded corners to reduce stress concentration and facilitate splicing operation.

[0134] The thickness of the lap plate 3141 can be selected according to the size of the filtration device 3, the pressure to be borne and the requirement for sealing performance. Generally speaking, thicker lap plates 3141 need to be selected for larger filtration devices 3 or under higher pressure conditions, so as to ensure sufficient structural strength and sealing performance.

[0135] The surface of the lap plate 3141 can be specially treated, such as providing anti-slip lines or protrusions on the lap surface. When multiple lap plates 3141 overlap with each other, the anti-slip lines or protrusions can increase the friction force to prevent the lap plates 3141 from relatively sliding during use, further improving the stability of the connection.

[0136] At least a part of the bottom of the sub-shell 314 is provided with a lapping plate 3141. When the sub-shells 314 are assembled, the lapping plates 3141 at the bottom of the sub-shells 314 will overlap each other in the vertical direction of the stirring device 100. This overlapping design makes the connection between the sub-shells 314 not only rely on the assembly of the edges, but also increases the connection area and stability through the overlapping of the bottom lapping plates 3141, thereby improving the integrity and sealing of the entire shell 31 structure, which is of great significance in terms of bearing liquid pressure and preventing leakage, and provides a guarantee for the reliable operation of the filter device 3.

[0137] In some embodiments, referring to Figures 6 to 7 , part of the lapping plate 3141 is provided with a lapping groove 31411, and at least part of the adjacent lapping plate 3141 can extend into the lapping groove 31411.

[0138] The lapping groove 31411 is a groove structure on the lapping plate 3141, which is matched in shape and size with the edge of the adjacent lapping plate 3141, and is used to accommodate at least part of the adjacent lapping plate 3141. Through this nested design, the connection between the lapping plates 3141 is further improved in terms of tightness and positioning accuracy, 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 shell 31.

[0139] The shape and size of the lapping plate 3141 can be diversified according to the size and shape of the sub-shell 314. For example, for a circular sub-shell 314, the lapping plate 3141 can be designed as an arc, and the width and thickness thereof are determined according to the pressure borne by the filter device 3 and the requirement for sealing. The lapping groove 31411 can be arranged at one side edge of the arc-shaped lapping plate 3141, the depth and width of the groove are matched with the thickness of the adjacent lapping plate 3141 and the size of the inserted part, and the inner wall of the groove can be polished to reduce the friction force during insertion. At the same time, some small protrusions or grooves can be arranged at the bottom of the groove to increase the friction between the inserted lapping plate 3141 and prevent it from accidentally falling out during use.

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

[0141] Some of the lapping plates 3141 are processed with special grooves, namely lapping grooves 31411. When the adjacent sub-housings 314 are spliced, a part of the corresponding lapping plate 3141 can be inserted into the lapping groove 31411, forming a nested connection similar to mortise and tenon. This design makes the connection between the lapping plates 3141 not just a simple plane overlap, but through the cooperation of the groove and the plate, increases the contact area and friction of the connection, improves the firmness and stability of the connection, and thus improves the structural strength and sealing performance of the entire filter device 3 shell 31, ensuring that the filter device 3 can better withstand liquid pressure and prevent leakage during operation.

[0142] In some embodiments, referring to Figures 1 to 7 , the stirring rod 2 is provided with a first liquid outlet hole 23 communicating with the mounting space 21, and the lapping plate 3141 is provided with a second liquid outlet hole 31412 communicating with the first liquid outlet hole 23.

[0143] The first liquid outlet hole 23 is a hole structure on the stirring rod 2, which is one of the channels for the exchange and circulation of liquid inside and outside the stirring rod 2. It communicates with the mounting space 21, so that the liquid can flow orderly between the stirring rod 2, the mounting space 21 and the subsequent connecting components (such as the second liquid outlet hole 31412 on the lapping plate 3141).

[0144] The second liquid outlet hole 31412 is a hole structure provided on the lapping plate 3141, located at the bottom of the filter space 312, and communicates with the first liquid outlet hole 23 on the stirring rod 2. Its main function is to guide the liquid filtered from the filter space 312 to the first liquid outlet hole 23 and flow out from the first liquid outlet hole 23.

[0145] The diameter of the first liquid outlet hole 23 can be designed in an adjustable form, for example, the hole wall is made of elastic material, and the diameter size is changed by external pressure device or electromagnetic control mechanism.

[0146] The shape of the second liquid outlet hole 31412 can be designed as an oval or a rectangle, which is adapted to the shape of the lapping plate 3141 and the flow direction of the liquid, so as to improve the passing efficiency of the liquid.

[0147] On the inner wall of the second liquid outlet hole 31412, some small flow guiding protrusions or grooves can be provided. These microstructures can guide the liquid to form a specific flow direction when flowing out of the second liquid outlet hole 31412, so that it can better blend with the liquid flow field inside the filter device 3, avoid turbulence or local flow speed too fast caused by improper liquid outflow direction, and affect the filtering effect.

[0148] The mounting space 21 inside the stirring rod 2 is communicated with the outside through the first liquid outlet hole 23, and the second liquid outlet hole 31412 on the lap plate 3141 is communicated with the first liquid outlet hole 23, so that a liquid channel is formed from the inside of the stirring rod 2, through the first liquid outlet hole 23, and then through the second liquid outlet hole 31412 to the other side of the lap plate 3141. When the stirring rod 2 rotates to stir the liquid, the liquid inside the stirring rod 2 can flow out of the filter device through this channel, so that the filtered liquid in the filtering space 312 can be continuously discharged from the filtering space 312 to accommodate the newly entering liquid for filtering, so as to ensure that the whole stirring and filtering device 3 can operate efficiently and stably.

[0149] In some embodiments, referring to

[0150] By setting the lowest point of the filtering part 32 to be lower than the highest point of the stirring wheel 1, the liquid entering from the stirring wheel 1 can be filtered in the filtering part 32 after entering the filtering space 312, and the liquid that is precipitated or flows downward after stirring can be filtered, thereby improving the filtering efficiency and treatment effect.

[0151] In some embodiments, referring to Figure 5 , the filtering part 32 includes a filter screen 321, and the filter screen 321 covers the second liquid outlet hole 31412 in the filtering space 312.

[0152] The filter screen 321 is a mesh material with a specific pore size or pore structure, which can intercept and separate solid particles, impurities, etc. in the liquid according to the pore size, allowing the liquid that meets the requirements to pass through, thereby achieving the purpose of purifying the liquid. The material, pore size, porosity, shape and structure of the filter screen 321 and other factors will affect its filtering performance, and different filtering requirements will select filter screens 321 with different characteristics to ensure the best filtering effect.

[0153] The filter screen 321 is arranged in the filtering device 3, and the filter screen 321 covers the second liquid outlet hole 31412 at the position of the filtering space 312. In this way, the liquid that has completed the filtering in the filtering space 312 can be subjected to a final filtering step again through the filter screen 321 before flowing out through the second liquid outlet hole 31412, thereby further improving the overall filtering effect and ensuring that the liquid that flows out meets higher purity standards and meets more stringent use or subsequent processing requirements.

[0154] In some embodiments, referring to Figure 5 , the filtering part 32 includes a filter core 322, and the filter core 322 is arranged in the filtering space 312.

[0155] The filter element 322 is a key component that realizes the filtering function in the filter part 32, and usually has specific structural and material properties. It is made of materials with filtering properties, such as filter paper, filter screen, membrane material, fiber material, etc. These materials are formed into a filter element 322 body with a certain pore structure through special processing technology, which can selectively retain impurities in the liquid according to the pore size and surface properties, and allow the required liquid to pass through, thereby achieving the purpose of filtration. The material, pore size distribution, filtration precision, dust holding capacity and service life of the filter element 322 are important indicators to measure its performance. Different application scenarios require different types of filter elements 322 to meet the corresponding filtering requirements.

[0156] The structure of the filter element 322 can be designed in various forms to adapt to different filtering requirements and working conditions. For example, for high-precision filtering requirements, a multi-layer composite filter element 322 structure can be used, such as an ultrafiltration membrane with fine pore structure inside, which is used to intercept small particles and colloidal substances, and an outer layer of pre-filter layer with larger pore size, which is used to preliminarily remove larger particle impurities. This multi-layer structure can not only ensure high filtration precision, but also prolong the service life of the filter element 322, preventing the microporous membrane from being quickly clogged by large particle impurities. In addition, the shape of the filter element 322 can also be diversified. In addition to the common cylindrical filter element 322, it can also be designed into a folded filter element 322, which increases the filtering area to improve the filtering efficiency, while reducing the volume of the filter element 322, suitable for filtering devices 3 with limited space.

[0157] The inside of the filter space 312 can be provided with special filter element 322 fixing structures, such as clamping grooves, supports or clamps, etc., to ensure the stability of the position of the filter element 322 in the filter space 312, and prevent displacement or damage due to the impact or vibration of the liquid flow. These fixing structures can be designed to be detachable, facilitating the installation and replacement operation of the filter element 322.

[0158] The main filtering element of the filter part 32 is the filter element 322, which is placed in the filter space 312 of the filtering device 3. This means that when the liquid enters the filter space 312, it will come into direct contact with the filter element 322, which will intercept and remove impurities in the liquid by virtue of its own filtering properties, such as specific pore size, porosity and adsorption performance, etc., so that the liquid passing through the filter element 322 is purified.

[0159] In some embodiments, referring to Figure 6 , the inside of the housing 31 is provided with a reinforcing rib plate 315, which divides the filter space 312 into a first sub-space 316 and a second sub-space 317, and both the first sub-space 316 and the second sub-space 317 are provided with filter elements 322.

[0160] In some embodiments, the filter element 322 is a mesh structure, and the shell 31 is provided with a hollow area where no liquid inlet hole 313 is arranged, and the filter element 322 covers the hollow area. After the liquid enters the filtering space 321, the water level in the filtering space 321 drops under the action of centrifugal force. Part 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 filtering space 321, leaving the lint in the liquid in the filtering 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 hole 31412.

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

[0162] By reasonably arranging the reinforcing rib plate 315, the external force can be effectively dispersed, the carrying capacity of the shell 31 can be improved, and it is ensured that the filtering device 3 can normally operate in a relatively harsh working environment. At the same time, the reinforcing rib plate 315 also has the function of separating the filtering space 312, which has an important influence on the flow path of the liquid and the filtering process.

[0163] The shape of the reinforcing rib plate 315 can be designed in various forms, such as straight plates, arc-shaped plates, wave-shaped plates, etc., to adapt to the structural requirements of different shapes of the shell 31 and the filtering space 312, and to meet different mechanical performance requirements.

[0164] The reinforcing rib plate 315 can be arranged along the edges or diagonal lines of the shell 31 to increase the bending and compression resistance of the shell 31. The thickness and height of the reinforcing rib plate 315 can also be adjusted according to the size of the shell 31, the pressure it bears, and the requirements for structural strength. Generally speaking, in the case of larger filtering devices 3 or higher pressure, thicker and higher reinforcing rib plates 315 need to be selected to ensure sufficient structural stability.

[0165] The first and second subspaces 316 and 317 are two relatively independent areas separated by the reinforcing rib plate 315 from the filtering space 312, each having a certain spatial range and geometric shape. The filter element 322 is arranged in each of the two subspaces, so that the filtering process can be carried out simultaneously in different areas, and the filtering conditions (such as flow, flow rate, filtering accuracy, etc.) of each subspace can be independently adjusted and optimized as needed, thereby improving the flexibility and adaptability of the entire filtering device 3, and meeting different filtering requirements and process requirements.

[0166] The shell 31 is additionally provided with reinforcing ribs 315, which divide the originally single filter space 312 into two parts, i.e., a first subspace 316 and a second subspace 317, and filter cartridges 322 are installed in both subspaces. When the liquid enters the filter device 3, it will flow into the first subspace 316 and the second subspace 317, respectively, and contact the corresponding filter cartridges 322 in the respective subspaces. After being filtered by the filter cartridges 322, the liquid flows out from the respective outlets or converges and then flows out. This design realizes multi-region and multi-level filtering operations in the same filter device 3 by reasonably dividing the filter space 312 and distributing the filter cartridges 322, improves the filtering efficiency and flexibility, and can better meet complex filtering requirements and different working conditions, optimizing the effect and stability of the entire filtering process.

[0167] In some embodiments, referring to Figures 1 to 7 , the filter device 3 includes a decorative piece 33, which is arranged at the end of the shell 31 away from the stirring wheel 1. The decorative piece 33 is connected to the shell 31, and the decorative piece 33 is provided with a first clamping part 331. The stirring rod 2 is provided with a second clamping part 22 at the end away from the stirring wheel 1, and the first clamping part 331 can be clamped and matched with the second clamping part 22.

[0168] As a component of the filter device 3, the main function of the decorative piece 33 is not only to improve the appearance of the equipment, make it more in line with the principles of ergonomics and aesthetics, and increase the market competitiveness of the product, but also to protect the shell 31, hide the internal structure, or connect other components. The material, shape, and color of the decorative piece 33 can be customized according to different application scenarios and user needs to achieve the organic combination of functionality and aesthetics.

[0169] The first clamping part 331 and the second clamping part 22 are specific structural components arranged on the decorative piece 33 and the stirring rod 2, respectively. The design purpose is to realize the quick and convenient connection between the decorative piece 33 and the stirring rod 2 through clamping and matching, while ensuring the stability and reliability of the connection. The shape, size, and structure of the clamping part can be various, such as clamping groove and clamping block, buckle and eyelet, elastic clamping ring and clamping groove, etc. The specific application requirements and design requirements are selected and optimized to meet different assembly and use conditions.

[0170] The specific structure of the first clamping part 331 and the second clamping part 22 can be innovatively designed to improve the stability and reliability of the clamping, while facilitating operation.

[0171] Exemplarily, the first clamping part 331 can be designed as a clamping hook with elasticity, and a clamping groove is arranged inside the clamping hook; and the second clamping part 22 is designed as a protrusion matched with the clamping groove. When the protrusion is inserted into the clamping groove, the clamping hook tightly holds the protrusion under the action of elasticity, thereby achieving firm clamping. Alternatively, the first clamping part 331 is designed as a ring-shaped elastic clamping ring, and the second clamping part 22 is designed as a cylinder with a ring-shaped groove. The clamping ring is sleeved on the groove of the cylinder, thereby achieving quick and stable clamping.

[0172] In addition, in order to prevent misoperation or accidental disconnection during clamping, some auxiliary structures such as positioning pins, anti-disconnection or locking devices can be arranged on the clamping parts. For example, a positioning pin is arranged on one side of the clamping part. When the two clamping parts are clamped, the positioning pin is inserted into the corresponding positioning hole, thereby ensuring the accuracy and stability of clamping. An anti-disconnection such as a rotatable buckle is arranged at the connection of the clamping part. After clamping is completed, the buckle is rotated to the locking position, thereby preventing accidental disconnection of the clamping part and improving the safety and reliability of the equipment.

[0173] The filter device 3 is provided with a decoration piece 33 which is mounted on the shell 31 away from the stirring wheel 1 and is fixed with the shell 31 through a certain connection mode. Meanwhile, the decoration piece 33 is provided with a first clamping part 331, and the stirring rod 2 is provided with a second clamping part 22 at the end thereof away from the stirring wheel 1. The two clamping parts can cooperate with each other to achieve clamping connection between the decoration piece 33 and the stirring rod 2. This design not only makes the stirring rod 2 and the filter device 3 functionally related to each other, but also realizes a specific connection mode through the decoration piece 33 in structure, thereby ensuring the relative position stability of the stirring rod 2 and the filter device 3, possibly simplifying the assembly process to some extent, and improving the appearance quality of the whole equipment through the arrangement of the decoration piece 33, thereby meeting the dual needs of users in function and aesthetics.
