[0009] In which, the feeding assembly is also provided with a accommodating chamber and a liquid supply channel. The accommodating chamber is provided at one end of the feeding assembly away from the stirring wheel, and the accommodating chamber is respectively connected to the guide channel and the liquid supply channel, and the liquid supply channel is connected to the outside of the stirring rod.

[0010] In one embodiment, the feeding assembly includes a rod body and a spiral blade. The rod body is arranged in the stirring rod and is spaced apart from the inner wall of the stirring rod along the radial direction of the stirring rod. The spiral blade is arranged on the outer periphery of the rod body and extends spirally along the axial direction of the rod body. The rod body and the spiral blade define the guide channel.

[0011] In one embodiment, the spiral blade abuts against the inner wall of the stirring rod.

[0012] In one embodiment, the feeding assembly further includes a feeding box provided with the accommodating cavity, the feeding box is provided at the end of the rod body away from the stirring wheel, the rod body is provided with the liquid supply channel, the liquid supply channel extends along the axial direction of the rod body, and the axial ends of the liquid supply channel are respectively connected to the accommodating cavity and the outside of the stirring rod.

[0013] In one embodiment, the feeding box includes a first sub-shell and a second sub-shell, the first sub-shell is arranged to form a lower liquid channel extending along the axial direction of the rod body, the second sub-shell is arranged around the outer periphery of the first sub-shell and defines the accommodating cavity with the first sub-shell, along the height direction of the stirring rod, the end of the second sub-shell away from the stirring wheel is higher than the end of the first sub-shell away from the stirring wheel, one axial end of the lower liquid channel is connected to the liquid supply channel, and the other end is open.

[0014] In one embodiment, the feeding box further includes a cover body, which is disposed in the second sub-shell and covers the first sub-shell, and a siphon channel is formed between the first sub-shell and the inner wall of the cover body, which is connected to the lower liquid channel and can produce a siphon effect.

[0015] In one embodiment, when projected on a plane perpendicular to the axis of the stirring rod, the projection of the accommodating cavity is annular, and the outer periphery of the projection of the liquid supply channel is located between the inner ring and the outer ring of the projection of the accommodating cavity.

[0016] In one embodiment, the side of the accommodating cavity away from the stirring wheel is open to form an opening, and the guide channel is connected to the accommodating cavity through the opening.

[0017] In one embodiment, a feeding port is provided at one end of the stirring rod away from the stirring wheel, and when projected onto a plane perpendicular to the axis of the stirring rod, there is an overlapping area between the projection of the feeding port and the projection of the opening.

[0018] In one embodiment, one end of the stirring rod away from the stirring wheel forms a stop wall, the stop wall is annular, and the inner ring wall of the stop wall is arranged to form the feeding port.

[0019] In one embodiment, the height difference between the stop wall and the opening gradually decreases radially inwardly of the stirring rod.

[0020] In one embodiment, the stirring rod includes a rod body and a stirring cap, one end of the rod body is arranged on the stirring wheel, and the stirring cap is arranged on the end of the rod body away from the stirring wheel, and the rod body is a hollow tube structure.

[0022] In a second aspect, an embodiment of the present application provides a washing device, comprising a washing tub and a stirring device as described in any one of the above embodiments, wherein the stirring device is rotatably disposed in the washing tub.

[0023] The stirring device of the present embodiment utilizes a water inlet, a diversion channel, a receiving chamber, and a liquid supply channel to automatically dispense washing aid. The water inlet is located at the end of the stirring rod closest to the stirring wheel, i.e., the height of the water inlet is relatively low, thereby facilitating the flow of water from the washing drum of the washing device through the water inlet and into the diversion channel. The receiving chamber, which is used to hold the washing aid, is located at the end of the feeding assembly away from the stirring wheel, i.e., the height of the receiving chamber is relatively high. As the stirring device rotates, the diversion channel rotates synchronously. Since the diversion channel extends helically along the axis of the stirring rod, the height of the water flow in the diversion channel can be raised. When the stirring device is operated at a relatively low speed, the water flowing into the diversion channel through the water inlet will not be lifted to a height where it can flow into the receiving chamber. In this state, the washing aid in the receiving chamber will not be dispensed into the washing tub. When the stirring device is operated at a relatively high speed, the water flowing into the diversion channel through the water inlet will be lifted to a height where it can flow into the receiving chamber. After entering the receiving chamber, the water will mix with the washing aid contained in the receiving chamber to form a mixed liquid. The mixed liquid is then supplied to the washing tub through the liquid supply channel, thereby achieving automatic dispensing of the washing aid. In other words, the stirring device of the embodiment of the present application can achieve automatic dispensing of the washing aid by controlling the rotation speed of the stirring device, while the stirring device itself needs to rotate. This method of achieving the automatic dispensing function of the washing aid is relatively simple to control and easy to implement. At the same time, the washing equipment does not need to add components such as an electric pump, which is conducive to controlling the cost of the washing equipment.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. The following embodiments are only used to more clearly illustrate the technical solutions of the present application and are therefore only used as examples and are not intended to limit the scope of protection of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] In the description of the embodiments of this application, the technical terms "first," "second," "third," etc. are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly specify the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise specifically defined.

[0032] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0034] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0035] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the technical term "contact" should be understood in a broad sense, and can be direct contact, contact through an intermediate medium layer, contact with essentially no interaction force between the two contacting parties, or contact with interaction force between the two contacting parties.

[0036] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] An embodiment of the present application provides a washing device, which includes a washing drum and a stirring device according to any embodiment of the present application.

[0038] It should be noted that the washing equipment can be an agitator washing machine, a pulsator washing machine, a washer-dryer, etc., and there is no limitation here.

[0039] The washing tub is used to accommodate laundry, which may be clothing or other items that need to be washed. The top side of the washing tub is provided with an opening, through which a user can put in or take out laundry.

[0040] Taking an agitator washing machine as an example, an agitator washing machine may include only a washing drum, in which case the washing drum can hold both washing water and clothes. An agitator washing machine may also include an outer drum, in which the washing drum is disposed, the outer drum being used to hold washing water, and the inner drum being used to hold clothes. Of course, in some embodiments, an agitator washing machine may include both a washing drum and an outer drum, in which the washing drum can hold both washing water and clothes, and the water in the washing drum will not enter the outer drum.

[0041] The stirring device is rotatably disposed within the washing drum. It is understood that the stirring device rotates when the washing apparatus is in a washing state. For example, in some embodiments, the washing apparatus includes a motor and a reducer, and the motor shaft of the motor drives the stirring device through the reducer to rotate, thereby enhancing the agitation effect of the water flow, which is beneficial for improving the washing effect of the clothes. At the same time, the stirring device also has a better effect on preventing the laundry from being entangled in the area above the washing drum.

[0042] The rotation direction of the stirring device is not limited. For example, it can rotate forward or reverse. Forward and reverse are only used to indicate that the two rotation directions are opposite, and do not specify a specific direction.

[0043] It should be noted that during the washing process, the stirring device rotates and the washing drum may rotate or not rotate, and there is no limitation here.

[0044] Please also refer to Figures 1 to 4 The embodiment of the present application further provides a stirring device, wherein the stirring device 100 includes a stirring wheel 10 , a stirring rod 20 and a feeding assembly 30 .

[0045] The surfaces of the stirring wheel 10 and the stirring rod 20 may be provided with a plurality of water-repelling ridges. When the stirring device 100 rotates, the water-repelling ridges move the water flow and the laundry, and the water-repelling ridges can enhance the stirring effect of the water flow.

[0046] The specific shape of the stirring wheel 10 is not limited. Figure 1 As shown, the stirring wheel 10 can be a circular structure, so that the stirring wheel 10 is easy to rotate.

[0047] The stirring wheel 10 is located at the bottom of the washing drum, and one end of the stirring rod 20 is provided on the stirring wheel 10, that is, the stirring rod 20 extends along the height direction of the stirring device 100. Specifically, the "height direction" is as follows: Figure 2 As shown, it should be noted that the “height direction” in the embodiment of the present application needs to be understood according to the orientation relationship of the washing device in normal use. The “height direction” is substantially parallel to the axial direction of the stirring rod 20.

[0048] The specific structure of the stirring rod 20 is not limited. Figure 2 As shown, the stirring rod 20 is a hollow structure, so that the feeding assembly 30 can be easily arranged inside the stirring rod 20.

[0049] A water outlet 21a is provided at one end of the stirring rod 20 close to the stirring wheel 10, and the feeding assembly 30 is arranged in the stirring rod 20 and rotates synchronously with the stirring rod 20. The feeding assembly 30 is provided with a guide channel 30a extending spirally along the axial direction of the stirring rod 20, and the water outlet 21a connects the guide channel 30a and the outside of the stirring rod 20.

[0050] Water in the washing tub can flow through the water inlet 21a and into the diversion channel 30a. Because the diversion channel 30a is a spiral channel, the water entering the diversion channel 30a is lifted by the diversion channel 30a as the feeding assembly 30 rotates with the stirring rod 20. It is understood that the higher the rotation speed of the stirring rod 20, the higher the water is lifted by the diversion channel 30a.

[0051] It should be noted that, during the process of the guide channel 30a spirally extending along the axial direction of the stirring rod 20, the extension length of the guide channel 30a along the circumference of the stirring rod 20 is not limited. For example, the extension length may not exceed the circumference of the stirring rod 20; of course, the extension length may also exceed one or more circumferences of the stirring rod 20.

[0052] It is understandable that under the condition that the distance between the two ends of the guide channel 30a along the axial direction of the stirring rod 20 is constant, the larger the angle of inclination of the guide channel 30a relative to the axial direction of the stirring rod 20, the longer the extension length of the guide channel 30a along the axial direction of the stirring rod 20.

[0053] The number of the guide channels 30a is not limited. For example, it can be one or more. In an embodiment where there is one guide channel 30a, it is equivalent to a single helical structure; in an embodiment where there are multiple guide channels 30a, it is equivalent to a multi-helical structure.

[0054] When there are multiple diversion channels 30a, each diversion channel 30a is independent of each other, and water can enter any diversion channel 30a and be lifted.

[0055] The number of water outlets 21a is not limited. Figure 1 As shown, there are multiple water inlets 21a, which are spaced apart along the circumference of the stirring rod 20. Water in the washing tub can enter the stirring rod 20 through each water inlet 21a, thereby increasing the flow rate of water in the guide channel 30a.

[0056] It should be noted that, in the embodiments of the present application, a plurality refers to any number of two or more.

[0057] In other embodiments, only one water outlet 21a may be provided.

[0058] The feeding assembly 30 is also provided with a accommodating chamber 33a and a liquid supply channel 31a. The accommodating chamber 33a is provided at one end of the feeding assembly 30 away from the stirring wheel 10, and the accommodating chamber 33a is respectively connected to the guide channel 30a and the liquid supply channel 31a, and the liquid supply channel 31a is connected to the outside of the stirring rod 20.

[0059] The communication mode between the liquid supply channel 31a and the outside is not limited. Figure 2As shown, the liquid supply channel 31a is also connected to the interior of the stirring rod 20. The stirring device 100 is provided with a water outlet 100a. The mixed liquid flowing out of the liquid supply channel 31a enters the stirring rod 20 and then enters the washing tub through this water outlet 100a. The interior space of the stirring rod 20 can be understood as a container. The water outlet 21a should be located above the bottom wall of the container. The water outlet 100a should be located below the height of the water outlet 21a and as close to the bottom wall of the container as possible.

[0060] The accommodating chamber 33a is used to accommodate a washing aid. The type of the washing aid is not limited, and may be, for example, a detergent, a softener, etc. In the embodiment of the present application, the washing aid is used as a softener for illustration.

[0061] Softener is a laundry care product that's typically added to the washing tub after the laundry is rinsed, during the rinse cycle. This ensures even distribution of the softener across the laundry fibers and avoids mixing softener with detergent, which can lead to reduced softening or uneven distribution.

[0062] The diversion channel 30a is used to guide the water flow into the accommodating chamber 33a. The water flows into the accommodating chamber 33a and mixes with the softener contained in the accommodating chamber 33a to form a mixed liquid. The mixed liquid can flow out of the accommodating chamber 33a through the liquid supply channel 31a and return to the washing tub.

[0063] Because the accommodating chamber 33a is located at the end of the feeding assembly 30 away from the stirring wheel 10, the height of the accommodating chamber 33a is relatively high. In other words, the stirring rod 20 needs to be operated at a certain speed before the diversion channel 30a can lift the water flow to a height that allows it to flow into the accommodating chamber 33a. Specifically, the stirring rod 20 needs to be operated at a speed not lower than the set speed before the diversion channel 30a can lift the water flow to a height that allows it to flow into the accommodating chamber 33a. The "set speed" is the speed of the stirring rod 20 corresponding to when the diversion channel 30a just lifts the water flow to a height that allows it to flow into the accommodating chamber 33a.

[0064] When the stirring rod 20 is running at a speed lower than the set speed, even if the water in the washing tub flows through the water inlet 21a and enters the diversion channel 30a, it cannot enter the accommodating chamber 33a. At this time, the washing aid contained in the accommodating chamber 33a will not be dispensed into the washing tub. However, when the stirring rod 20 reaches the set speed, the diversion channel 30a raises the water flow to a height that allows it to flow into the accommodating chamber 33a. After entering the accommodating chamber 33a, the water flows and mixes with the washing aid contained in the accommodating chamber 33a to form a mixed liquid. The mixed liquid is then supplied to the washing tub through the liquid supply channel 31a, thereby achieving the dispensing of the softener. In other words, the automatic dispensing of the washing aid can be achieved by controlling the speed of the stirring rod 20.

[0065] In the related art, washing equipment uses an electric pump or other delivery method to achieve automatic delivery of washing aids. This delivery method is relatively expensive and relatively complex to control, making it inconvenient to implement.

[0066] The stirring device of the embodiment of the present application utilizes a water inlet 21a, a flow guide channel 30a, a receiving chamber 33a, and a liquid supply channel 31a to automatically dispense washing aid. The water inlet 21a is located at the end of the stirring rod 20 near the stirring wheel 10, i.e., the height of the water inlet 21a is relatively low, thereby facilitating the flow of water from the washing drum of the washing device through the water inlet 21a and into the flow guide channel 30a. The receiving chamber 33a is used to accommodate washing aid and is located at the end of the feeding assembly 30 away from the stirring wheel 10, i.e., the height of the receiving chamber 33a is relatively high. During the rotation of the stirring device 100, the flow guide channel 30a rotates synchronously. Since the flow guide channel 30a extends in a spiral along the axial direction of the stirring rod 20, the height of the water flow in the flow guide channel 30a can be raised. When the stirring device 100 is operating at a relatively low speed, the water flowing into the guide channel 30a through the water inlet 21a is not lifted to a height where it can flow into the receiving chamber 33a. In this state, the washing aid in the receiving chamber 33a is not dispensed into the washing tub. However, when the stirring device 100 is operating at a relatively high speed, the water flowing into the guide channel 30a through the water inlet 21a is lifted to a height where it can flow into the receiving chamber 33a. After entering the receiving chamber 33a, the water mixes with the washing aid contained in the receiving chamber 33a to form a mixed liquid. The mixed liquid is then supplied to the washing tub through the liquid supply channel 31a, thereby achieving automatic dispensing of the washing aid. In other words, the stirring device of the embodiment of the present application can achieve automatic dispensing of the washing aid by controlling the rotation speed of the stirring device 100, while the stirring device 100 itself needs to rotate. This method of achieving the automatic dispensing function of the washing aid is relatively simple to control and easy to implement. At the same time, the washing machine does not need to add components such as an electric pump, thereby helping to control the cost of the washing machine.

[0067] The specific method of forming the diversion channel 30a by the feeding assembly 30 is not limited. Figure 2 and Figure 4 The feeding assembly 30 includes a rod body 31 and a spiral blade 32. The rod body 31 is arranged in the stirring rod 20 and is spaced apart from the inner wall of the stirring rod 20 along the radial direction of the stirring rod 20. The spiral blade 32 is arranged on the outer periphery of the rod body 31 and extends spirally along the axial direction of the rod body 31. The rod body 31 and the spiral blade 32 define a guide channel 30a.

[0068] The spiral blade 32 is a blade having a helical shape, and the blade extends helically along the axial direction of the rod body 31. The structure of the spiral blade 32 is relatively simple, thereby facilitating the formation of the guide channel 30a.

[0069] In other embodiments, the rod body 31 is provided with a spiral groove along its axial direction, and the space in the spiral groove constitutes the guide channel 30a. In this embodiment, the structure of the rod body 31 is similar to that of a screw.

[0070] In one embodiment, please refer to Figure 2 The spiral blade 32 abuts against the inner wall of the stirring rod 20 .

[0071] Please refer to Figure 4 The outer peripheral side of the guide channel 30a around the axial direction of the rod body 31 is relatively open. In this embodiment, it can be understood that the inner wall of the stirring rod 20 closes this open side, and the sealing performance of the guide channel 30a is relatively good. During the rotation of the stirring rod 20, the water flow through the water inlet 21a and into the guide channel 30a is basically confined within the guide channel 30a, thereby facilitating the guide channel 30a to raise the height of the water flow. In other words, the stirring rod 20 does not need to rotate at a very high speed, that is, it can raise the water flow in the guide channel 30a to the required height. The threshold of the set speed of the stirring shaft corresponding to the guide channel 30a to guide the water flow into the accommodating chamber 33a is not too high, thereby facilitating the delivery of washing aid.

[0072] In other embodiments, the spiral blade 32 may not contact the inner wall of the stirring rod 20. That is, there is a gap between the two. Therefore, the inner wall of the stirring rod 20 will not block the open side of the guide channel 30a. During the rotation of the stirring rod 20, after the water flows through the water inlet 21a and enters the guide channel 30a, it may also flow downward through the gap between the spiral blade 32 and the stirring rod 20, thereby increasing the difficulty of the guide channel 30a in raising the water flow height. In other words, the threshold for the set speed of the stirring shaft corresponding to the water flow directed by the guide channel 30a into the accommodating chamber 33a will not be too low, which helps to avoid the accidental addition of washing aid.

[0073] In one embodiment, please refer to Figure 2 and Figure 3The feeding assembly 30 further includes a feeding box 33 having a receiving cavity 33a. The feeding box 33 is provided at one end of the rod body 31 away from the stirring wheel 10. The rod body 31 is provided with a liquid supply channel 31a. Specifically, Figure 3 As shown, the feeding box 33 and the inner wall of the stirring rod 20 are spaced apart along the radial direction of the stirring rod 20, and the guide channel 30a guides the water flow into the gap, and then flows into the accommodating cavity 33a through the gap.

[0074] like Figure 2 As shown, the rod body 31 is roughly a hollow tube structure, which can be formed to obtain the liquid supply channel 31a, which facilitates the formation of the liquid supply channel 31a; at the same time, the liquid supply channel 31a is formed on the rod body 31, and the structure of the feeding box 33 is simpler.

[0075] The liquid supply channel 31 a extends along the axial direction of the rod body 31 , and two axial ends of the liquid supply channel 31 a are communicated with the accommodating cavity 33 a and the outside of the stirring rod 20 , respectively.

[0076] The extension direction of the liquid supply channel 31a is nearly parallel to the height direction of the stirring device 100. After the water flow carrying the washing aid enters the liquid supply channel 31a, it can flow downward under the action of gravity, thereby facilitating the addition of the washing softener.

[0077] Furthermore, because the spiral blades 32 are disposed on the rod body 31 and define a flow channel 30a with the rod body 31, the height of the liquid supply channel 31a at the end away from the accommodating chamber 33a is lower than that of the flow channel 30a. Furthermore, because the water outlet 21a and the flow channel 30a are directly connected, the height of the liquid supply channel 31a at the end away from the accommodating chamber 33a is also lower than that of the water outlet 21a. In other words, during the automatic dispensing of wash aid, the flow path of the water in the washing tub directed by the flow channel 30a into the accommodating chamber 33a does not overlap with the flow path of the mixed liquid in the accommodating chamber 33a supplied to the washing tub through the flow channel 31a. Consequently, the entire flow path of the automatic dispensing of wash aid is smoother, which helps reduce flow resistance during the dispensing process and thereby improves dispensing efficiency.

[0078] In one embodiment, please refer to Figure 2 and Figure 3 The feeding box 33 includes a first sub-shell 331 and a second sub-shell 332. The first sub-shell 331 is surrounded by a lower liquid channel 331a extending axially along the rod body 31. The second sub-shell 332 is surrounded by the outer periphery of the first sub-shell 331 and defines a accommodating cavity 33a with the first sub-shell 331.

[0079] Along the height direction of the stirring rod 20, the end of the second sub-shell 332 away from the stirring wheel 10 is higher than the end of the first sub-shell 331 away from the stirring wheel 10. That is, the height of the top wall of the second sub-shell 332 is higher than the height of the top wall of the first sub-shell 331.

[0080] One axial end of the lower liquid channel 331a is connected to the liquid supply channel 31a, and the other end is open.

[0081] After the water flow is introduced into the accommodating chamber 33a, the liquid level in the accommodating chamber 33a gradually rises. After the liquid level rises to the height of the top wall of the first sub-shell 331, the second sub-shell 332 can continue to block the mixed liquid, allowing the mixed liquid to overflow into the lower liquid channel 331a, and then enter the liquid supply channel 31a to complete the delivery of the washing aid.

[0082] In this embodiment, the automatic feeding of the washing aid is achieved by overflowing. This feeding method is relatively simple, and the structure of the feeding box 33 is also relatively simple, which is easy to implement.

[0083] In one embodiment, please refer to Figure 2 and Figure 3 The feeding box 33 also includes a cover body 333, which is arranged in the second sub-shell 332 and covers the first sub-shell 331. A siphon channel 33b is formed between the inner wall of the first sub-shell 331 and the cover body 333, which is connected to the lower liquid channel 331a and can produce a siphon effect.

[0084] In this embodiment, as the liquid level in the accommodating chamber 33a gradually rises, the communicating vessel principle causes the liquid level in the siphon channel 33b to also gradually rise. Once the liquid level in the siphon channel 33b reaches the top of the lower liquid channel 331a, the mixed liquid enters the lower liquid channel 331a, creating a siphon effect. When the diversion channel 30a no longer directs water into the accommodating chamber 33a, the siphon effect causes the liquid level in the accommodating chamber 33a to gradually decrease to below the top wall of the first sub-shell 331. This allows the washing aid contained in the accommodating chamber 33a to be dispensed as fully as possible, thereby reducing waste.

[0085] In one embodiment, please refer to Figure 2 and Figure 3 When projected on a plane perpendicular to the axial direction of the stirring rod 20, the projection of the accommodating chamber 33a is annular, and the outer periphery of the projection of the liquid supply channel 31a is located between the inner ring and the outer ring of the projection of the accommodating chamber 33a.

[0086] In other words, when projected on a plane perpendicular to the axis of the stirring rod 20 , the projection of the first subshell 331 is located within the projection of the liquid supply channel 31 a , and the projection of the peripheral wall of the second subshell 332 is arranged around the periphery of the projection of the rod body 31 .

[0087] In this embodiment, under the condition that the internal space of the stirring rod 20 is certain, the volume of the accommodating cavity 33a can be increased as much as possible, which is conducive to improving the containing capacity of the accommodating cavity 33a, so that more washing aids can be contained.

[0088] In one embodiment, please refer to Figure 2 and Figure 3 The side of the accommodating chamber 33a away from the stirring wheel 10 is open to form an opening 332a, and the guide channel 30a is connected to the accommodating chamber 33a through the opening 332a.

[0089] The opening 332a corresponds to the highest point of the accommodating chamber 33a. As the liquid level in the accommodating chamber 33a rises, this helps reduce the chance of the mixed liquid overflowing through the opening 332a. It is understood that once the liquid level in the accommodating chamber 33a reaches the height of the opening 332a, the mixed liquid in the accommodating chamber 33a will occupy the space where the opening 332a is located, preventing water from flowing outside the accommodating chamber 33a from entering the accommodating chamber 33a through the opening 332a, thereby affecting the dispensing of the wash aid. In this embodiment, the liquid level in the accommodating chamber 33a is less likely to reach the height of the opening 332a, thereby facilitating the smooth dispensing of the wash aid.

[0090] In one embodiment, please refer to Figure 2 and Figure 3 A feeding port 221a is provided at one end of the stirring rod 20 away from the stirring wheel 10. The user can feed washing aid into the accommodating chamber 33a through the feeding port 221a.

[0091] When projected onto a plane perpendicular to the axial direction of the stirring rod 20 , there is an overlapping area between the projection of the feeding port 221 a and the projection of the opening 332 a .

[0092] The user can add washing aid to the accommodating chamber 33a through the feeding port 221a. After passing through the feeding port 221a, the washing aid can fall under the action of gravity and enter the accommodating chamber 33a through the opening 332a, thereby completing the replenishment of the washing aid in the accommodating chamber 33a.

[0093] Specifically, the projection of the opening 332a may cover the projection of the feeding port 221a. Thus, the washing aid falling through the feeding port 221a can basically enter the accommodating cavity 33a through the opening 332a, thereby helping to reduce the waste of washing aid.

[0094] In addition, in the embodiment where the stirring rod 20 includes a rod body 21 and a stirring cap 22 (details will be explained below), the user can add washing aid into the accommodating chamber 33a without removing the stirring cap 22, thereby facilitating the user's operation.

[0095] In one embodiment, please refer to Figure 2 and Figure 3 The end of the stirring rod 20 away from the stirring wheel 10 forms a stop wall 221, and the stop wall 221 is annular. The inner ring wall of the stop wall 221 is surrounded to form a feeding port 221a.

[0096] The stop wall 221 has a stopping effect on the water flow, thereby changing the flow direction of the water flow, which is beneficial to reducing the amount of water flow rushing out of the stirring rod 20 through the feeding port 221a, that is, the water flow can flow into the accommodating chamber 33a through the opening 332a as much as possible, thereby increasing the liquid level in the accommodating chamber 33a, and then realizing the overflow of the mixed liquid in the accommodating chamber 33a to the lower liquid channel 331a and completing the liquid supply.

[0097] In one embodiment, please refer to Figure 2 and Figure 3 , along the radial direction inward of the stirring rod 20, the height difference between the stop wall 221 and the opening 332a gradually decreases.

[0098] The stop wall 221 produces a certain diversion effect. After the water flows through the stop wall 221, the flow direction is changed to downward, thereby helping to further reduce the amount of water flowing out of the stirring rod 20 through the feeding port 221a.

[0099] In one embodiment, please refer to Figure 1 and Figure 4 The stirring rod 20 includes a rod body 21 and a stirring cap 22. One end of the rod body 21 is arranged on the stirring wheel 10, and the stirring cap 22 is arranged on the end of the rod body 21 away from the stirring wheel 10. The rod body 21 is a hollow tube structure.

[0100] It should be noted that in the embodiment where the stirring rod 20 is provided with a feeding port 221 a , the feeding port 221 a is provided on the stirring cap 22 ; in the embodiment where the stirring rod 20 is provided with a stop wall 221 , the stirring cap 22 is provided with the stop wall 221 .

[0101] During the assembly process of the stirring device 100 , the feeding assembly 30 is first installed inside the rod body 21 , and then the stirring cap 22 is connected to the rod body 21 , thereby facilitating the installation of the feeding assembly 30 .

[0102] The connection method between the rod body 21 and the stirring cap 22 is not limited. Figure 1 and Figure 4 The stirring cap 22 and the rod body 21 are detachably connected.

[0103] The specific connection mode of the detachable connection is not limited. For example, it can be a snap connection, a plug connection, or a fastener fastening connection, etc. For example, Figure 4As shown, the stirring cap 22 is provided with a first clamping portion 22a, and the rod body 21 is provided with a second clamping portion 21b. One of the first clamping portion 22a and the second clamping portion 21b is a buckle, and the other is a card interface. The stirring cap 22 is sleeved on the rod body 21, and the buckle and the card interface are engaged to complete a detachable connection between the rod body 21 and the stirring cap 22.

[0104] After the feeding assembly 30 is installed inside the stirring rod 20, if the feeding assembly 30 needs to be removed again, since the rod body 21 and the stirring cap 22 are assembled using a detachable connection, the stirring cap 22 can be easily removed from the rod body 21, thereby facilitating the removal of the feeding assembly 30.

[0105] In other embodiments, the rod body 21 and the stirring cap 22 may also be connected by a non-detachable connection method such as welding.
