[0042] It should be noted that the washing equipment can be a stirring type washing machine, a pulsator type washing machine, a washing and drying integrated machine, etc., which is not limited herein.

[0043] The washing drum is used to accommodate washing objects, which can be clothes, shoes, carpets, etc., and the top side of the washing drum has an opening through which the user can put in or take out the washing objects.

[0044] For example, the agitator washing machine can only include the washing drum, at this time, the washing drum can hold washing water and contain clothes; the agitator washing machine can also include an outer drum, the washing drum is arranged in the outer drum, the outer drum is used for holding washing water, and the washing drum is used for containing clothes.

[0046] The rotation direction of the stirring device is not limited. For example, it can be forward rotation and reverse rotation. The forward rotation and the reverse rotation are only to indicate that the rotation directions of the two are opposite, and do not specify a certain direction.

[0047] 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 here.

[0048] 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 outward in the radial direction 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 for filtering at least part of the liquid flowing into the filtering space 312.

[0049] 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.

[0050] The stirring wheel 1 is one of the core components of the stirring device 100, which is usually driven to rotate by a motor. Its shape and structure are various, such as paddle type, turbine type, etc. The centrifugal force and shear force generated by high-speed rotation make the stirred substances produce strong convection and diffusion in the container, so as to achieve the purpose of uniform mixing.

[0051] The stirring rod 2 is connected with the stirring wheel 1, which plays a role in auxiliary stirring and liquid transmission, and has a mounting space 21 inside for placing the filtering device.

[0052] The blade 24 is a part of the stirring rod 2, and a part of the stirring rod 2 is radially outwardly convex 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, and the blade 24 rotates with it. The blade 24 causes the liquid to flow through interaction with the liquid.

[0053] The filtering device 3 is used to separate and remove impurities, particles and the like in the liquid. The filtering device 3 includes a shell 31, a filtering part 32 and the like, and realizes effective filtering of the liquid through specific structural design.

[0054] The shell 31 serves as the external structure of the filtering device 3, and plays a role in protecting the internal components and forming a specific flow channel and space. The shape of the shell 31 is not limited here and can be designed as a cylinder or a square, which is optimized according to the installation space 21 and the principle of fluid mechanics.

[0055] The filtering part 32 is a key part of the filtering device 3 that directly realizes the filtering function. It usually uses filter screens, filter cartridges 322 and the like as filtering media. According to the particle size and properties of the substances to be filtered, appropriate filtering accuracy and material are selected to effectively intercept impurities in the liquid.

[0056] The specific type of the filtering part 32 is not limited here. In addition to the common filter screens and filter cartridges 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 of impurities, and then multiple layers of filter screens or filtering media of different accuracy 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, thereby realizing 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 shell 31 to ensure that the liquid can only pass through the filtering media for filtering, prevent unfiltered liquid from leaking from the gap, and ensure the reliability of the filtering effect.

[0057] The filtering space 312 provides a place for the filtering process, and the liquid passage hole 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. The liquid passage hole 313 plays a role in connecting 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 smoothly flow from the liquid inlet hole 4 into the filtering space 312, and is an intermediate bridge for the liquid transmission.

[0058] 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 initially enter the device. It provides a source of liquid to be treated for the entire stirring device 100, and the liquid begins to enter the subsequent treatment process from here.

[0059] The specific position of the liquid inlet hole 4 is not limited here. For example, the liquid inlet hole 4 can be a hole formed in the stirring rod 2, or a hole formed in the stirring wheel 1. Of course, multiple holes formed in the stirring rod 2 and the stirring wheel 1 can also be used as the liquid inlet hole 4.

[0060] The height direction of the stirring device 100 is not limited here. For the convenience of description, the height direction of the stirring device 100 is the direction shown in the figure.

[0061] In the related art, the washing device is provided with a filter device in the barrel. During the washing process, the lint and other sundries carried by the liquid from the washing objects can be filtered and collected by the filter device. However, the conventional filter device is an integrated shell. When the user cleans or maintains, the impurities can only be removed from one end or a small window. The maintenance is difficult.

[0062] In the embodiments of the present application, please refer to Figure 6 The shell 31 includes at least two sub-shells 314, which are spliced along the circumference of the shell 31 to form the filter space 312.

[0063] 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 forming the filter space 312.

[0064] The shape of the sub-shell 314 can be designed in various forms, such as an arc-shaped plate, a polygonal plate, etc., to adapt to different filter device 3 shapes and structural requirements. For example, for a circular filter 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 filter 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 tenon and mortise, clamping slot or thread connection structure, which facilitates the quick and accurate splicing between the sub-shells 314, and ensures the sealing performance and structural strength after splicing.

[0065] The material of the sub-shell 314 can be selected according to the filtering environment and requirements. For example, for filtering of corrosive liquid, corrosion-resistant stainless steel, plastic (such as polytetrafluoroethylene), or ceramic can be used; for filtering in a high-temperature environment, high-temperature-resistant alloy materials or special ceramic materials can be used. In addition, the inner surface of the sub-shell 314 can be treated in a special way, such as being coated with a smooth coating (such as a Teflon coating) to reduce the adhesion and flow resistance of the liquid on the inner wall of the sub-shell 314 and improve the filtering efficiency; or some micro flow guide structures, such as micro grooves or protrusions, can be arranged to guide the flow direction of the liquid in the filtering space 312 and optimize the filtering effect.

[0066] The sub-shells 314 can be connected in various ways, such as welding, bolt connection, buckle connection, or sealant connection. Welding connection can provide high connection strength and sealing performance, and is suitable for filtering devices 3 with high requirements for structural strength and sealing performance, but this connection method is relatively fixed and is not conducive to subsequent disassembly and maintenance; bolt connection is detachable, which facilitates replacement of the sub-shells 314 or maintenance of the interior of the filtering device 3, but attention should be paid to the sealing treatment of the bolts to prevent liquid leakage; buckle connection is simple and fast to operate, can realize quick assembly and disassembly, and is suitable for occasions where the filtering part 32 needs to be frequently replaced or the equipment needs to be cleaned; the sealant connection can form a sealing layer at the joint of the sub-shells 314, effectively preventing liquid leakage, and also has a certain buffering and damping effect, which is suitable for filtering systems with high sealing requirements and small vibration.

[0067] In the embodiments of the present application, the outer shell 31 is not an integrally formed component, but is composed of at least two sub-shells 314 which are spliced along the circumferential direction of the outer shell 31 and tightly combined together through a suitable connection method to finally enclose a space for accommodating the filtering medium and performing liquid filtering operation, i.e. the filtering space 312. This design makes the manufacturing and assembly of the outer shell 31 more flexible, and also facilitates maintenance, repair of the interior of the filtering device 3, and adjustment of the size and shape of the filtering space 312 according to actual requirements, which provides the possibility for optimization and diversification of the entire filtering device 3.

[0068] 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 part of the lap overlap area in the height direction of the stirring device 100.

[0069] The lap plate 3141 is a plate-shaped structure arranged at the bottom of at least part of the sub-shell 314. Its main function is to cooperate with the lap plates 3141 on other sub-shells 314, form a lap overlap area in the height direction of the stirring device 100, realize closer and more stable connection between the sub-shells 314, and at the same time, enhance the sealing performance and structural strength of the entire outer shell 31 at the bottom area, prevent liquid from leaking from the joint gap at the bottom of the sub-shell 314, cause the gap to be blocked / leak the dust, and ensure the normal operation and filtering effect of the filtering device 3.

[0070] 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 of the sub-shell 314 and jointing requirements. For example, for a circular sub-shell 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 jointed at the bottom, improving the tightness of the connection; for a square sub-shell 314, a rectangular lap plate 3141 is more suitable, and the edges can be provided with chamfers or rounded corners to reduce stress concentration and facilitate jointing operation.

[0071] The thickness of the lap plate 3141 can be selected according to the size of the filtering device 3, the pressure it bears, and the requirement for sealing performance. Generally speaking, for larger filtering devices 3 or under higher pressure, thicker lap plates 3141 need to be selected to ensure sufficient structural strength and sealing performance.

[0072] 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 each other, these anti-slip lines or protrusions can increase the friction to prevent the lap plates 3141 from slipping relative to each other during use, further improving the stability of the connection.

[0073] At least part of the bottom of the sub-shell 314 is provided with a lap plate 3141, and when these sub-shells 314 are jointed and combined, the lap plates 3141 at the bottom of each sub-shell 314 will partially overlap in the vertical height direction of the stirring device 100. This overlapping design makes the connection between the sub-shells 314 not only rely on the jointing of the edges, but also increase the connection area and stability through the overlapping of the bottom lap plates 3141, thereby improving the integrity and sealing performance of the structure of the entire outer shell 31, which is of great significance in terms of bearing liquid pressure and preventing leakage, and provides a guarantee for the reliable operation of the filtering device 3.

[0074] In some embodiments, referring to Figures 6 to 7 , part of the lap plate 3141 is provided with a lap groove 31411, and at least part of the adjacent lap plate 3141 can extend into the lap groove 31411.

[0075] The lap joint groove 31411 is a groove structure on the partial lap joint plate 3141, which is shaped and sized to fit the edge of the adjacent lap joint plate 3141, for accommodating at least a portion of the adjacent lap joint plate 3141. Through this nested design, the connection tightness and positioning accuracy between the lap joint plates 3141 are further improved, and the reliability and stability of the connection between the sub-housings 314 are enhanced, thereby optimizing the structural performance of the entire filter device 3 housing 31.

[0076] The shape and size of the lap joint plate 3141 can be variously designed according to the size and shape of the sub-housing 314. For example, for a circular sub-housing 314, the lap joint plate 3141 can be designed as an arc, with its width and thickness determined according to the pressure borne by the filter device 3 and the requirement for sealing. The lap joint groove 31411 can be provided on one side edge of the arc-shaped lap joint plate 3141, with the depth and width of the groove matched with the thickness of the adjacent lap joint plate 3141 and the size of the inserted portion. The inner wall of the groove can be polished to reduce the friction force during insertion, while some small protrusions or grooves can be provided at the bottom of the groove to increase the friction force between the inserted lap joint plate 3141, preventing it from accidentally coming out during use.

[0077] For a square or rectangular sub-housing 314, the lap joint plate 3141 can be designed as a rectangular plate, with the lap joint groove 31411 located at one end or both sides of the plate. The lap joint groove 31411 can be shaped as a rectangle, trapezoid, dovetail, or the like, with different shapes of the lap joint groove 31411 having different connection characteristics.

[0078] Some of the lap joint plates 3141 are processed with specific grooves, i.e., the lap joint groove 31411. When the adjacent sub-housings 314 are spliced, a portion of the corresponding lap joint plate 3141 can be inserted into the lap joint groove 31411, forming a nested connection similar to a mortise and tenon joint. This design makes the connection between the lap joint plates 3141 no longer simply a flat overlap, but through the cooperation of the groove and the plate, the contact area and friction force of the connection are increased, the firmness and stability of the connection are improved, and thus the structural strength and sealing performance of the entire filter device 3 housing 31 are enhanced, ensuring that the filter device 3 can better withstand liquid pressure and prevent leakage during operation.

[0079] In some embodiments, referring to Figures 1 to 8 , at least part of the edge of the liquid passing hole 313 protrudes away from the filtration space 312 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 communicate through the flow guide channel 3181.

[0080] The abutment portion 318 is a structure protruding from the edge of at least part of the liquid passage hole 313. The abutment 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.

[0081] The arrangement of the guide flow channel 3181 makes the flow path of the liquid from the liquid inlet hole 4 to the liquid passage hole 313 more definite and stable. It can avoid disordered flow, backflow, etc. between the liquid inlet hole 4 and the liquid passage hole 313, ensuring that the liquid can smoothly enter the filter space 312 according to the designed path, and improving the efficiency and stability of liquid transmission.

[0082] The shape and size of the abutment portion 318 can be designed according to actual needs. For example, the abutment portion 318 can be a regular ring formed around the edge of the liquid passage hole 313, which can uniformly guide and restrict the liquid.

[0083] In some embodiments, at least part of the liquid inlet hole 4 is arranged on the stirring rod 2, and the outer shell 31 is provided with a liquid passage hole 313 at the corresponding position. The edge of each liquid passage hole 313 extends in the direction close to the liquid inlet hole 4 to form an abutment portion 318. After the filter device 3 is assembled with the stirring rod 2, the abutment portion 318 abuts against the liquid inlet hole 4 and seals the edge of the liquid inlet hole 4. The abutment 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 passage hole 313 under the guidance of the guide flow channel 3181. The abutment and sealing effect of the abutment portion 318 improves the efficiency of the liquid entering the filter space 312. The presence of the abutment portion 318 can enhance the sealing between the liquid inlet hole 4 and the liquid passage hole 313 to some extent. Since the abutment portion 318 tightly cooperates with the liquid inlet hole 4 to form the guide flow 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.

[0084] In some embodiments, each liquid passage hole 313 is provided with a corresponding abutment portion 318 to abut against the corresponding liquid inlet hole 4. Each abutment portion 318 can be connected to form an integral whole, forming a grid structure, and each grid opening corresponds to a liquid passage hole 313.

[0085] In some embodiments, at least part of the liquid inlet hole 4 is arranged on the water diversion ridge 11, and the water diversion ridge 11 has a water diversion cavity inside. The liquid entering from the liquid inlet hole 4 flows along the water diversion 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 towards the water diversion cavity. When the assembly is completed, the water diversion cavity is in communication with the water diversion channel 3181, thereby enabling the liquid inlet hole 4 to communicate with the liquid passing hole 313. The formed water diversion channel 3181 can guide the liquid entering from the liquid inlet hole 4 on the water diversion ridge 11 to the filter space 312.

[0086] 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 diversion ridge 11. At this time, the water diversion channel 3181 can be arranged in various ways. For example, one water diversion channel 3181 corresponds to one position of the liquid inlet hole 4, such as some water diversion channels 3181 corresponding to the liquid inlet hole 4 on the stirring rod 2, and some water diversion channels 3181 corresponding to the liquid inlet hole 4 on the water diversion ridge 11; or one water diversion channel 3181 corresponds to liquid inlet holes 4 at different positions, such as some water diversion channels 3181 extending to both the liquid inlet hole 4 on the stirring rod 2 and the liquid inlet hole 4 on the water diversion ridge 11, so that the liquid inlet hole 4 on the stirring rod 2 and the liquid inlet hole 4 on the water diversion ridge 11 can communicate with the same liquid passing hole 313, and enter the filter space 312 from the same liquid passing hole 313; of course, each water diversion channel 3181 can also correspond to only one liquid inlet hole 4, that is, each liquid inlet hole 4 communicates with one liquid passing hole 313 through one water diversion channel 3181, forming an independent channel.

[0087] In some embodiments, in order to prevent large particles from entering the filter 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 correspond 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 filter space 312, so that only the target filtering material such as lint can enter the filter space 312 for further filtering, thereby effectively reducing the entry of large-particle impurities into the filter device 3, and ensuring the smooth and efficient progress of the filtering process.

[0088] Each liquid passing hole 313 has a corresponding liquid inlet hole 4, which ensures the smooth transmission of liquid from the stirring rod 2 to the filter device 3, and avoids the phenomenon of liquid blockage or backflow caused by the mismatch of liquid passing holes. 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 filter space 312, the liquid to be filtered can fully contact each region of the filter part 32, thereby avoiding the situation of local over-filtering or under-filtering.

[0089] In some embodiments of the present application, please refer to Figures 1 to 7The shell 31 is provided with a flow blocking part 311, which is arranged in the filtering space 312 and at least blocks part of the liquid passing hole 313 along the height direction of the stirring device 100.

[0090] Through experiments, 1g of thread ends are added to the washing equipment under the condition that the washing equipment is at the medium water level, and the weight of the collected lint is tested for comparison experiments. Without the flow blocking part 311, the average collection rate of the filtering device is 86%. With the flow blocking part 311, the average collection rate of the filtering device is 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.

[0091] In some embodiments, the flow blocking part 311 is connected to the edge of the liquid passing hole 313, and the flow blocking part 311 is recessed in a direction away from the liquid passing hole 313 to form a flow blocking area 3111.

[0092] The flow blocking area 3111 is a specific shape formed by the recess of the flow blocking part 311, which functions to guide the liquid flowing into the filtering space from the liquid passing hole 313 to smoothly enter the filtering space while blocking the liquid in the filtering space from flowing out of the liquid passing hole.

[0093] The recessed shape of the flow blocking part 311 can be designed in various forms, for example, a parabolic-like recess, which can make the liquid gradually change direction and accelerate after entering the flow blocking area 3111, forming a relatively uniform flow rate distribution, suitable for filtering scenarios with high liquid flow rate requirements and large flow rate; or a smooth recess with a certain arc, such as a semicircular recess, which can make the liquid change direction smoothly in the flow blocking area 3111, reducing the generation of turbulence, and is more suitable for some fine filtering processes with high requirements for liquid flow stability.

[0094] In some embodiments, the flow blocking part 311 can be designed as a curved sheet structure with a certain arc, and can also be designed as an oval or a rectangle, etc., to adapt to different liquid flow requirements and blocking designs 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 and improve 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 installation of the flow blocking part 311 and the pressure brought by liquid flow.

[0095] In some embodiments, the flow blocking part 311 at least blocks a part of the liquid passing hole 313, specifically, the curved surface of the flow blocking part 311 extends from the top region to the bottom region of the liquid passing hole 313, for at least blocking the top region of the liquid passing hole 313, so that the liquid cannot directly enter from the top, but flows into the filter device 3 from the bottom unblocked region of the liquid passing hole 313 along the guidance of the flow blocking part 311, to meet the requirement that the flow blocking part 311 guides part of the liquid to the bottom of the filter device. In addition, the flow blocking part 311 blocks the top region of the liquid passing hole 313, that is, when the liquid entering the filter space 312 flows on the side wall of the filter space 312 under the action of centrifugal force when the stirring rod 2 rotates, the liquid cannot flow out from the top or upper blocked region of the liquid passing hole 313, reducing the amount of unfiltered liquid in the filter space 312 directly discharged from the liquid passing hole 313, and further improving the filtering effect and filtering efficiency.

[0096] Here, it should be noted that there may be part of the liquid flowing out from the bottom region of the liquid passing hole 313 which is not blocked 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 region of the liquid passing hole 313 which is not blocked by the flow blocking part 311, the amount of liquid entering the filter space 312 through the liquid passing hole 313 is greater than the amount of liquid thrown out from the filter space 312 due to the action of centrifugal force, so that during rotation, the liquid in the liquid passing hole 313 always flows into the inside of the filter space 312.

[0097] The edge of the liquid passing hole 313 can be specially treated, such as being polished into a round or chamfered corner, which can reduce the local turbulence and energy loss of the liquid when flowing in due to the sharp edge, so that the liquid can enter the flow blocking region 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 when the flow blocking part 311 is connected with the liquid passing hole 313, to ensure that all the entering liquid can be effectively guided by the flow blocking part 311, avoiding liquid leakage and affecting the filtering effect.

[0098] The flow blocking part 311 is arranged inside the filter space 312 of the filter device 3, and one end thereof is closely connected with the edge of the liquid passing hole 313. The shape of the flow blocking part 311 is not flat, but is concave in the direction away from the liquid passing hole 313, thereby constituting a specific space for guiding the flow of liquid, i.e. the flow blocking region 3111. When the liquid flows in from the liquid passing hole 313, it will first enter this flow blocking region 3111, and due to the special shape and space constraints of the flow blocking region 3111, the flow direction of the liquid will be changed, and instead of directly rushing into the inside of the filter space 312 in disorder, it will flow according to the path set by the flow blocking region 3111 to the bottom of the filter device 3.

[0099] 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. In this way, 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.

[0100] In some embodiments, referring to Figures 1 to 7 , along the height direction of the stirring device 100, the flow blocking part 311 extends from the top area to the bottom area of the liquid passing hole 313 and blocks at least half of the liquid passing hole 313.

[0101] The flow blocking part 311 covers an area of at least half of the top area 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 to achieve better filtering effect and device performance.

[0102] 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 during the operation of the stirring device 100, when the liquid in the filtering space 312 is thrown towards the liquid passing hole 313 under the action of centrifugal force, since 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, it can effectively block those liquids that try to escape from the filtering space 312 through the liquid passing hole 313, ensuring that as much liquid as possible completes the filtering process in the filtering space 312.

[0103] In this case, the shielding ratio of the flow blocking part 311 to the liquid passing hole 313 has multiple possibilities, which can be half or more than half. 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; on the contrary, the larger the area shielded by the flow blocking part 311, the greater the resistance of the liquid 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 requirement, and the operating parameters of the stirring device 100, so as to reasonably determine the shielding range of the flow blocking part 311, so as to ensure the filtering effect while considering the smooth inflow of the liquid, so that the whole stirring and filtering device 3 can run efficiently and stably.

[0104] 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 having a filtering part 32. The shell 31 is provided with a liquid passing hole 313. The liquid inlet hole 4 is in communication with the filtering space 312 through the liquid passing 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 through the liquid inlet hole 4 into the filtering space 312 of the filtering device 3, and then pass through the filtering part 32 for filtering. The lint and other impurities can be collected in the filtering part 32. The liquid filtered by the filtering part 32 can be returned to the washing drum, and the cycle is repeated in the washing process, so as to continuously filter the liquid in the washing drum, thereby reducing the content of the lint and other impurities in the liquid in the washing drum, and improving the problem of lint remaining on the clothes, and improving the washing effect and user experience. Moreover, the stirring device of the present application is provided with a flow blocking part, so that the liquid entering the filtering space cannot flow out from the shielded area of the liquid passing hole under the action of centrifugal force. The amount of unfiltered liquid in the filtering space directly discharged from the liquid passing hole can be reduced, and the filtering effect and efficiency can be improved.

[0105] In some embodiments, the liquid inlet hole 4 is in communication with the filtering space 312 through the liquid passing hole 313. At least part of the liquid inlet hole 4 is located below the blade 24 in the height direction of the stirring device 100.

[0106] When viewed from the bottom to the top of the stirring device 100, at least a part of the liquid inlet hole 4 is located 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 located below the blade 24, for example, part of the liquid inlet hole 4 is arranged on the stirring rod 2 or part of the liquid inlet hole 4 is arranged on the stirring wheel 1 below the stirring rod 2, 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.

[0107] In some embodiments, referring to Figures 1 to 7 , at least a part of the liquid inlet hole 4 is arranged on the stirring wheel 1.

[0108] The water-repelling ridge 11 is a structure formed by the protrusion of at least a part of the stirring wheel 1. During the rotation of the stirring wheel 1, the water-repelling ridge 11 can generate a pushing force on the liquid, 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.

[0109] The specific arrangement 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-repelling ridge 11. In this way, when the water-repelling ridge 11 rotates, the pressure generated by the side surface of the water-repelling ridge 11 during the interaction with the liquid can press the liquid into the liquid inlet hole 4.

[0110] It should be noted that since the stirring wheel 1 is connected with 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.

[0111] Arranging the liquid inlet hole 4 on the water-repelling ridge 11 can enable the liquid below the stirring rod 2 to enter the stirring device 100 and then enter the filtering space 312 through the liquid inlet hole 4 on the water-repelling ridge 11 under the driving action of the water-repelling ridge 11, so as to improve the liquid inlet amount of the filtering space, and the liquid filtering efficiency is obviously improved especially under the low water level working condition.

[0112] In some embodiments, referring to Figures 1 to 7 , at least a part of the liquid inlet hole 4 is arranged on the stirring rod 2.

[0113] The distribution of the liquid inlet holes 4 on the stirring rod 2 is not limited here. For example, the liquid inlet holes 4 can be uniformly distributed on a specific area of the stirring rod 2, so that the liquid can enter the stirring device 100 more evenly. Alternatively, the liquid inlet holes 4 can be concentrated on one side of the stirring rod 2, for example, on the side of the stirring rod 2 with the blades 24, so that the liquid can be mixed with the liquid in the stirring area more quickly after entering.

[0114] The stirring rod 2 occupies a certain space height along the height direction of the stirring device 100. The liquid inlet holes 4 are arranged on the stirring rod 2. On the one hand, under the driving action of the blades 24 of the stirring rod 2, the liquid can flow from the liquid inlet holes 4 on the stirring rod 2 into the filtering space 312 for filtering. On the other hand, as the liquid level rises, the liquid surface will gradually submerge the stirring rod 2. At this time, the liquid inlet holes 4 arranged 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 through the liquid inlet holes 4 for filtering treatment. In addition, since the liquid inlet holes 4 are 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.

[0115] In some embodiments, referring to Figure 2 , the projections of all the liquid inlet holes 4 on the outer surface of the shell 31 along the radial direction of the stirring rod 2 are located within the projection range of the liquid passing hole 313.

[0116] When observing from the radial direction of the stirring rod 2 and projecting the liquid inlet holes 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 indicates that in the spatial position, the liquid inlet holes 4 and the liquid passing hole 313 exhibit a specific nested structure relationship along the radial direction. Specifically, along the radial direction of the stirring rod 2, the liquid inlet holes 4 are in a nested state of the liquid passing hole 313. Through such a design, the liquid flowing from the liquid inlet holes 4 can be maximized to enter the subsequent filtering process through the liquid passing hole 313, thereby improving the efficiency and quality of the filtering and ensuring that more liquid can be effectively filtered.

[0117] In terms of 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 liquid leaking from the gap between the two during the transfer 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 achieve a tight fit without any gap between them, thereby completely eliminating the risk of liquid leakage from the gap between them. However, considering the need for convenience in actual assembly operations, a certain gap between the liquid inlet hole 4 and the liquid passing hole 313 can be allowed, but the size of this gap should be controlled within a range of less than 2 mm. Such a design can not only meet the convenience requirements of the assembly process, but also control the amount of liquid leakage during the transfer process to an acceptable low level, thereby ensuring the overall performance of the equipment while taking into account the actual operational needs during the production and manufacturing process.

[0118] In some embodiments, referring to Figures 1 to 7 , the vane 24 extends helically along the height direction of the stirring rod 2, the liquid inlet hole 4 is arranged near the root of the vane 24, and at least part of the liquid inlet hole 4 is arranged along the extension direction of the vane 24.

[0119] The stirring rod 2 forms vanes 24 by protruding radially outward in some areas, and these vanes 24 extend helically along the height direction of the stirring rod 2. This design enables the stirring rod 2 to more effectively push the liquid to flow and mix when it rotates.

[0120] The shape of the vane 24 can be designed to have a certain curvature and twist, rather than just a simple planar spiral shape. This twisted vane 24 can generate a more complex flow field when it rotates, not only having a height direction and 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 vane 24 can be specially textured, such as being engraved with micro grooves or protrusions. These microstructures can increase the degree of turbulence of the liquid when it flows over the surface of the vane 24, promoting the diffusion and mixing of substances in the liquid and improving the stirring quality.

[0121] The vane 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 vane 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 ring of flexible rubber sealing material can be provided on the edge of the vane 24, which can tightly fit the surface of the stirring rod 2 when the vane 24 is installed on the stirring rod 2, preventing liquid from leaking from the connection between the vane 24 and the stirring rod 2, and ensuring the sealing and stability of the stirring process.

[0122] Meanwhile, the liquid inlet holes 4 are arranged near the roots of the blades 24. When the stirring rod 2 rotates, the blades 24 cause the liquid to flow, and the roots of the blades 24 bear relatively large liquid pressure during the rotation of the stirring rod 2. The liquid inlet holes 4 arranged at this position help the liquid to be pressed into the liquid inlet holes 4 more efficiently, thereby improving the filtering efficiency.

[0123] Furthermore, the liquid inlet holes 4 are arranged along the extension direction of the blades 24. In this way, no matter the liquid level is at what height, there are liquid inlet holes 4 immersed in the liquid, thereby expanding the application range of the stirring device 100 and enabling the stirring device 100 to maintain good filtering performance and working stability under different liquid level conditions.

[0124] In some embodiments, the "liquid inlet holes 4 near the roots of the blades 24" means that when the 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.

[0125] The blades 24 spirally extending on the stirring rod 2 can generate strong height direction and circumferential flow fields when rotating, so that the liquid forms a complex circulating flow in the stirring container, thereby enhancing the shear force and turbulence degree of the liquid and improving the uniformity and efficiency of the stirring. The design that the liquid inlet holes 4 are arranged near the roots of the blades 24 and partially along the extension direction of the blades 24 enables the liquid to pass in and out of the stirring rod 2 through the liquid inlet holes 4 more efficiently under the action of the flow field generated by the rotation of the blades 24.

[0126] In some embodiments, referring to Figure 1 , the roots of the blades 24 are provided with the liquid inlet holes 4 on both sides.

[0127] The roots of the blades 24 are provided with the liquid inlet holes 4 on both sides. In this way, no matter the stirring rod 2 rotates clockwise or counterclockwise, there are liquid inlet holes 4 in the maximum pressure area formed by the roots of the blades 24, thereby expanding the application range of the stirring device 100 and enabling the stirring device 100 to efficiently operate under different rotation direction conditions, ensuring that the liquid exchange and stirring effect are not affected by the rotation direction and maintaining stable and good working performance.

[0128] 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, which communicates with the first liquid outlet hole 23.

[0129] 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 between the inside and outside of the stirring rod 2. It is in communication with the mounting space 21, so that the liquid can flow orderly between the inside of the stirring rod 2, the mounting space 21 and the subsequent connecting components (such as the second liquid outlet hole 31412 on the lap plate 3141).

[0130] The second liquid outlet hole 31412 is a hole structure arranged on the lap plate 3141 and located at the bottom of the filtering space 312. It is in communication with the first liquid outlet hole 23 on the stirring rod 2, and mainly functions to guide the liquid filtered from the filtering space 312 to the first liquid outlet hole 23 and then out of the first liquid outlet hole 23.

[0131] The diameter of the first liquid outlet hole 23 can be designed to be adjustable, for example, the hole wall is made of elastic material, and the diameter is changed by external pressure device or electromagnetic control mechanism.

[0132] 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 lap plate 3141 and the flow direction of the liquid, so as to improve the passing efficiency of the liquid.

[0133] On the inner wall of the second liquid outlet hole 31412, some small flow guiding protrusions or grooves can be arranged. 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 filtering device 3, avoiding turbulence or excessive local flow rate caused by improper liquid outflow direction, which affects the filtering effect.

[0134] The mounting space 21 inside the stirring rod 2 is in communication with the outside through the first liquid outlet hole 23, and the second liquid outlet hole 31412 on the lap plate 3141 is in communication with the first liquid outlet hole 23, so as to form a liquid channel from the inside of the stirring rod 2 through the first liquid outlet hole 23, 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 filtering device through this channel. In this way, the filtered liquid in the filtering space 312 can be continuously discharged from the filtering space 312 to accommodate the newly entered liquid for filtering, so as to ensure that the whole stirring and filtering device 3 can operate efficiently and stably.

[0135] In some embodiments, along the height direction of the stirring device 100, the lowest point of the filtering part 32 is lower than the highest point of the stirring wheel 1.

[0136] By setting the lowest point of the filtering part 32 to be lower than the highest point of the stirring wheel 1, thus, the liquid entering from the stirring wheel 1 can also be filtered in the filtering part 32 after entering the filtering space 312 at low water level, and the liquid after stirring, sedimentation or flowing downward is filtered, improving the filtering efficiency and treatment effect.

[0137] 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.

[0138] 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, so as to achieve 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. Different filtering requirements will select filter screens 321 with different characteristics to ensure the best filtering effect.

[0139] 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 filtered in the filtering space 312 can be filtered again by the filter screen 321 before flowing out through the second liquid outlet hole 31412, so as to further improve the overall filtering effect and ensure that the liquid flowing out meets higher purity standards and meets more stringent use or subsequent processing requirements.

[0140] 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.

[0141] The filter core 322 is a key element for realizing the filtering function of the filtering part 32, and usually has specific structure and material properties. It is made of materials with filtering properties, such as filter paper, filter screen, membrane material, fiber material, etc. These materials form a filter core 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, allowing the liquid that meets the requirements to pass through, so as to achieve the purpose of filtering. The material, pore size distribution, filtering accuracy, dust holding capacity and service life of the filter core 322 are important indicators to measure its performance. Different application scenarios require selection of different types of filter cores 322 to meet the corresponding filtering requirements.

[0142] 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 for intercepting small particles and colloidal substances, and an outer layer of pre-filter layer with larger pore size for preliminary removal of larger particle impurities. This multi-layer structure can not only ensure high filtering precision, but also prolong the service life of the filter element 322 and prevent 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 as a folded filter element 322 to increase the filtering area and improve the filtering efficiency while reducing the volume of the filter element 322, which is suitable for filtering devices 3 with limited space.

[0143] The inside of the filtering 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 filtering space 312 and prevent displacement or damage due to the impact or vibration of liquid flow. These fixing structures can be designed to be detachable to facilitate the installation and replacement operation of the filter element 322.

[0144] The main filtering element of the filtering part 32 is the filter element 322, which is placed in the filtering space 312 of the filtering device 3. This means that when the liquid enters the filtering 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 characteristics, such as specific pore size, porosity and adsorption performance, etc., so that the liquid passing through the filter element 322 is purified.

[0145] In some embodiments, referring to Figure 6 The inside of the housing 31 is provided with a reinforcing rib plate 315, which divides the filtering 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.

[0146] In some embodiments, the filter element 322 is a mesh structure, and the housing 31 is provided with a hollow area where there is no liquid inlet hole 313, 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 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.

[0147] 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.

[0148] By reasonably arranging the reinforcing rib plate 315, the external force can be effectively dispersed, and the carrying capacity of the shell 31 can be improved, ensuring that the filter device 3 can operate normally in a more severe working environment. At the same time, the reinforcing rib plate 315 also has the function of separating the filter space 312, which has an important influence on the flow path of the liquid and the filtering process.

[0149] 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 filter space 312, and to meet different mechanical performance requirements.

[0150] The reinforcing rib plate 315 can be arranged along the edge or diagonal direction 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 filter devices 3 or higher pressure, thicker and higher reinforcing rib plates 315 need to be selected to ensure sufficient structural stability.

[0151] The first sub-space 316 and the second sub-space 317 are two relatively independent areas separated by the reinforcing rib plate 315 in the filter space 312. Each has a certain spatial range and geometric shape, and a filter core 322 is arranged in each sub-space. This allows the filtering process to be carried out simultaneously in different areas, and the filtering conditions (such as flow, flow rate, filtering accuracy, etc.) of each sub-space can be independently adjusted and optimized as needed, thereby improving the flexibility and adaptability of the entire filter device 3 and meeting different filtering requirements and process requirements.

[0152] The reinforcing rib plate 315 is added inside the shell 31, which divides the originally single filter space 312 into two parts, namely the first sub-space 316 and the second sub-space 317, and filter cores 322 are installed in both sub-spaces. When the liquid enters the filter device 3, it will flow into the first sub-space 316 and the second sub-space 317 respectively, and contact the corresponding filter core 322 in each sub-space. After the filtering action of the filter core 322, the liquid flows out from the respective outlets or merges and flows out. This design realizes multi-region, multi-level filtering operation in the same filter device 3 through reasonable separation of the filter space 312 and distribution of the filter core 322, improves the filtering efficiency and flexibility, and better meets complex filtering requirements and different working conditions, optimizing the effect and stability of the entire filtering process.

[0153] In some embodiments, referring to Figures 1 to 7 , the filter device 3 comprises a decorative piece 33 arranged at the end of the housing 31 away from the stirring wheel 1, the decorative piece 33 is connected with the housing 31, and the decorative 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 away from the stirring wheel 1, and the first clamping part 331 can be clamped and matched with the second clamping part 22.

[0154] 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 housing 31, hide the internal structure or connect other components to some extent. The material, shape and color of the decorative piece 33 can be customized according to different application scenarios and user needs to realize the organic combination of functionality and aesthetics.

[0155] The first clamping part 331 and the second clamping part 22 are special structural components arranged on the decorative piece 33 and the stirring rod 2 respectively, and the design purpose is to realize the quick and convenient connection between the decorative piece 33 and the stirring rod 2 through the clamping and matching between them, 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., which can be selected and optimized according to the specific application requirements and design requirements to meet different assembly and use conditions.

[0156] 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 the operation.

[0157] Exemplarily, the first clamping part 331 can be designed as a clamping hook structure with elasticity, which is provided with a clamping groove inside, 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 will tightly hold the protrusion under the action of elasticity, realizing firm clamping; or the first clamping part 331 is designed as a ring-shaped elastic clamping ring, and the second clamping part 22 is designed as a cylindrical body with a ring-shaped groove, and the clamping ring is sleeved on the groove of the cylindrical body to realize quick and stable clamping.

[0158] In addition, in order to prevent misoperation or accidental disconnection during clamping, some auxiliary structures can be arranged on the clamping part, such as positioning pins, anti-unclamping or locking devices, etc. For example, a positioning pin is arranged on one side of the clamping part, when the two clamping parts are clamped, the positioning pin will be inserted into the corresponding positioning hole, to ensure the accuracy and stability of clamping; an anti-unclamping device such as a rotatable buckle is arranged at the connection of the clamping part, which is rotated to the locking position after clamping is completed, to prevent accidental disconnection of the clamping part, and to improve the safety and reliability of the equipment.

[0159] The filter device 3 is equipped with a decoration piece 33 which is installed on the shell 31 away from the stirring wheel 1, and the decoration piece 33 is fixed with the shell 31 by some connection mode. At the same time, 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 away from the stirring wheel 1, and the two clamping parts can cooperate with each other to realize the 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, which not only ensures the relative position stability of the stirring rod 2 and the filter device 3, but also may simplify the assembly process to a certain extent, and also improves the appearance quality of the whole equipment through the setting of the decoration piece 33, meeting the dual needs of users in function and aesthetics.
