At the same time, the added filter screen can filter and screen the foam, making the foam of the laundry detergent mixture dispensed outward more dense and further improving the efficiency of laundry detergent dispensing.

[0020] By placing the foaming nozzle structure at the outlet of the water channel of the dispensing device, the laundry detergent mixture is mixed with atmospheric gas to form dense foam. The foamy mixture is then dispensed into the outer drum of the laundry detergent equipment. This achieves the foaming and dispensing of the laundry detergent, allowing the foamy laundry detergent to directly act on the clothes in the drum, thereby achieving the effect of intensive washing of the clothes in the drum. This represents a significant technological advancement that greatly improves the contact efficiency between the laundry detergent and the clothes, and significantly enhances the washing effect of the clothes.

Therefore, they should not be construed as limitations on this application.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] This application describes a dispensing device for a garment processing equipment, used to automatically dispense garment processing agent into the water tank of the garment processing equipment. The garment processing equipment can be any existing device capable of processing garments, such as a top-loading washing machine, a front-loading washing machine, a washer-dryer combo, a dryer, an iron, a garment processing cabinet, etc. In this application embodiment, for ease of description, a top-loading washing machine is used as an example for discussion. The garment processing equipment includes a shell, and an outer tub is provided inside the shell. The outer tub is used to hold water, thus forming the aforementioned water tank. A washing component, driven by a motor to rotate and agitate the water in the outer tub, can be installed inside the outer tub, such as an inner tub, a pulsator, an agitator column, a second pulsator, etc. The outer tub of the aforementioned garment processing equipment has a vertically oriented axis and an upward-facing opening. An inner tub, coaxially arranged, is installed inside the outer tub. A control panel is installed on the top of the outer casing, and a garment processing agent dispensing device is provided on the control panel. The dispensing device is connected to the water inlet structure of the garment processing equipment to allow water to enter the outer tub from the opening. At the same time, the dispensing device also has a structure for adding garment processing agent, so that the garment processing agent is added into the outer tub along with the water flow to process the garments inside.

[0044] In this embodiment, the garment cleaning agent dispensing device includes a foaming nozzle structure 15. The foaming nozzle structure 15 is located at the outlet 12 of the dispensing water channel 5 of the dispensing device. It is used to mix the garment cleaning agent mixture with atmospheric gas to form dense foam, and to dispense the foamy mixture into the outer drum of the garment cleaning equipment. This achieves the foaming and dispensing of the garment cleaning agent, allowing the foamy garment cleaning agent to directly act on the clothes in the drum, thereby achieving the effect of intensive washing of the clothes in the drum. This represents a significant technological advancement that greatly improves the contact efficiency between the garment cleaning agent and the clothes and significantly enhances the washing effect of the clothes.

[0045] like Figures 1 to 13As shown in the embodiment of this application, the foaming nozzle structure 15 includes: a foaming mixing chamber 151, a filter section 152, and a dispensing nozzle 153; the foaming mixing chamber 151 is connected to the outside atmosphere through an air intake channel 154, and the dispensed clothing treatment agent generates negative pressure when passing through the foaming mixing chamber 151, using the negative pressure to draw in outside atmospheric gas; the filter section 152 is disposed between the foaming mixing chamber 151 and the dispensing nozzle 153, the clothing treatment agent in the foaming mixing chamber 151 and the inhaled gas mix to generate dense foam, and the dense foam-like mixture is filtered by the filter section 152 and then dispensed outward through the dispensing nozzle 153.

[0046] With the above settings, the foaming nozzle directly uses the negative pressure generated when the laundry detergent flows to draw in and mix with the outside air, achieving the effect of mixing and foaming the laundry detergent mixture. At the same time, the added filter screen can filter and screen the foam, making the foam of the laundry detergent mixture dispensed outward more dense and further improving the efficiency of laundry detergent dispensing.

[0047] In this embodiment of the application, the two opposite ends of the foaming mixing chamber 151 are the inlet end and the outlet end, respectively. For ease of description, the upper end is the inlet end and the lower end is the outlet end as an example. Of course, other left-right settings, tilting settings, and other methods can also be used to set the inlet end and the outlet end. Meanwhile, the inlet end of the foaming mixing chamber 151 is provided with an inlet hole 158, and the outlet end is connected to the dispensing nozzle 153 via the filter part 152; the side wall of the foaming mixing chamber 151 is provided with an air intake 157, which is connected to the air intake channel 154; the aperture of the inlet hole 158 is smaller than the radial dimension of the foaming mixing chamber 151, and the aperture of the air intake 157 is smaller than the aperture of the inlet hole 158. The flowing clothing treatment agent mixture creates a negative pressure in the foaming mixing chamber 151 due to the Venturi effect of the liquid flow, so as to draw in the outside atmospheric gas through the air intake channel 154 and the air intake 157 into the foaming mixing chamber 151, so that the drawn-in atmospheric gas mixes with the flowing clothing treatment agent mixture to produce a foam-like clothing treatment agent mixture, thereby achieving the effect of dispensing the densely foamed clothing treatment agent outward.

[0048] In this embodiment, the sidewall of the foaming mixing chamber 151 is composed of an inner and outer double-layer sandwich structure; the inner sandwich wall 155 surrounds the foaming mixing chamber 151, and the sandwich space between the outer sandwich wall 156 and the inner sandwich wall 155 constitutes the air intake channel 154; the air intake port 157 is provided on the inner sandwich wall 155 and is used to connect the foaming mixing chamber 151 and the air intake channel 154 on both sides of the inner sandwich wall 155; the inlet end of the sandwich space is closed, and the outlet end is open and connected to the outside atmosphere.

[0049] In this embodiment of the application, the inner and outer double-layer sandwich structure of the foaming mixing cavity 151 of the foaming spray structure can be composed of the same component, or it can be composed of two upper and lower components spliced ​​together; for example, a part is integrated on the upper cover 106 of the first housing 102 of the clothing processing equipment, and another independent part is fastened and installed on the lower side of the upper cover 106 of the first housing 102, and the two parts are spliced ​​together to form an inner and outer double-layer sandwich structure.

[0050] In this embodiment, the filter section 152 covers and is laid on the outlet end of the foaming mixing chamber 151; the dispensing nozzle 153 has a nozzle 159 extending outward along the axial direction of the foaming mixing chamber 151. The diameter of the nozzle 159 is smaller than the radial dimension of the foaming mixing chamber 151 and larger than the diameter of the inlet 158 ​​of the foaming mixing chamber 151. This ensures that atmospheric gas can be drawn into the foaming mixing chamber 151 by utilizing the pressure difference, while also extending the residence time of the clothing treatment agent mixture and the air intake in the foaming mixing chamber 151 by utilizing the nozzle 159 to improve the mixing and foaming efficiency.

[0051] In this embodiment, the inner interlayer wall 155 has a plurality of radially penetrating notches arranged at intervals near the inlet end. The notches constitute the air intake 157, so that the air intake 157 is set close to the inlet hole 158, allowing the clothing treatment agent mixture flowing into the foaming mixing chamber 151 to be directly mixed with the intake gas, thereby improving the foaming efficiency of the clothing treatment agent mixture.

[0052] In this embodiment, the inlet end of the foaming mixing chamber 151 is closed and has multiple inlet holes 158. The upper end of each inlet hole 158 is connected to the water channel 5 of the dispensing device integrated in the upper cover 106, and the lower end of each inlet hole 158 is connected to the foaming mixing chamber 151 enclosed by the inner layer wall 155 of the foaming mixing chamber 151. The inlet holes 158 are arranged at equal intervals around the axis of the foaming mixing chamber 151. Optionally, three inlet holes 158 are provided at the top of the foaming mixing chamber 151, and the three inlet holes 158 are arranged at equal intervals around the axis of the foaming mixing chamber 151.

[0053] Meanwhile, in this embodiment, each inlet 158 ​​is a tapered opening with a gradually narrowing size along the liquid inlet direction, so as to guide the clothing treatment agent mixture more smoothly from the inlet 158 ​​into the foaming mixing chamber 151. Optionally, in order to further improve the liquid flow effect at the inlet 158, multiple guide notches 160 arranged at intervals and extending in different radial directions can be provided on the outer periphery of the inlet 158. The bottom of the guide notches 160 extends downward from the outer periphery to the inner periphery to guide the water inlet. The laundry detergent mixture in 5 flows into the foaming mixing chamber 151 through the inlet 158; the guide opening 160 is a strip-shaped fan-shaped groove protruding outward from the radial direction of the inlet 158, so as to maximize the coverage area of ​​the inlet 158 ​​and more smoothly guide the laundry detergent mixture in the water channel 5 into the foaming mixing chamber 151; optionally, the maximum outer diameter of the guide opening 160 is larger than the radial dimension of the inlet 158, so as to further increase the guiding effect of the guide opening 160.

[0054] like Figures 1 to 13 As shown in the embodiment of this application, the garment treatment agent dispensing device includes a first body 100 and a second body 200. The first body 100 and the second body 200 are independently arranged, and the first body 100 is located outside the second body 200. This makes the dispensing device composed of two unrelated body parts, achieving the effect of modular and partitioned installation of the dispensing device, and thus achieving a significant technical advancement in improving the installation diversity of the dispensing device. Through the above arrangement, the effect of modular and partitioned installation of the dispensing device is achieved, thus achieving a significant technical advancement in improving the installation diversity of the dispensing device. Through the above arrangement, different functional components of the dispensing device are separately arranged, meeting the diverse installation needs of the dispensing device and greatly enriching the installation methods of the garment treatment agent dispensing device. In particular, through the above arrangement, a liquid filling port can be set in the drawer section on the dispensing part, achieving a significant technical advancement in using the drawer section to add and inject garment treatment agent into the separately arranged liquid storage section.

[0055] like Figures 1 to 13 As shown in the embodiment of this application, the garment treatment agent dispensing device further includes at least one connecting pipe 300; the two ends of the connecting pipe 300 are respectively connected to the first body 100 and the second body 200, so that the components of the dispensing device located on different bodies are connected through the connecting pipe 300, so as to achieve the effect of adding, injecting, extracting and dispensing garment treatment agent.

[0057] The aforementioned garment treatment agent is any existing additive used to treat garments, such as detergent, bleach, fabric softener, disinfectant, fragrance, etc.; for ease of description, this will not be discussed further in this embodiment.

[0058] like Figures 1 to 7 As shown in the embodiment of this application, the garment treatment agent dispensing device includes a first body 100 and a second body 200. The first body 100 is independently disposed outside the second body 200. The first body 100 is provided with a dispensing part 101, and the second body 200 is provided with a liquid storage part 201. A connecting pipe 300 is provided between the two bodies, and the liquid storage part 201 is connected to the dispensing part 101 through the connecting pipe 300.

[0059] The above-described configuration allows for the separate installation of different functional components of the dispensing device, meeting diverse installation and usage requirements and greatly enriching the installation options for the garment cleaning agent dispensing device. In particular, the addition port 8 can be installed in the drawer section 103 on the dispensing section 101, representing a significant technological advancement in adding garment cleaning agent to the separately configured liquid storage section 201 using the drawer section 103.

[0060] In this embodiment, the connecting pipe 300 includes a liquid filling connecting pipe 301 and a dispensing connecting pipe 302. The liquid filling connecting pipe 301 and the dispensing connecting pipe 302 are independently arranged and are used to allow the clothing treatment agent to flow from the dispensing part 101 to the storage part 201 and from the storage part 201 to the dispensing part 101, respectively. The clothing treatment agent injected at the dispensing part 101 enters the storage part 201 through the liquid filling connecting pipe 301 for storage. The clothing treatment agent stored in the storage part 201 is drawn out to the dispensing part 101 and dispensed externally through the dispensing connecting pipe 302.

[0061] With the above configuration, the dispensing section 101, which dispenses water outward, also integrates the function of adding and injecting laundry detergent, greatly enriching the diversity of dispensing device configurations; in particular, the drawer section 103 on the dispensing section 101, which can be pulled outward, can be used to add and inject laundry detergent into the liquid storage section.

The front opening of the first housing 102 is connected to the inner circumferential space of the control panel and the opening of the outer bucket, so as to realize the effect of the dispensing device dispensing water and a mixture of water and clothing treatment agent into the outer bucket.

[0063] In this embodiment, a slide rail structure is provided between the left and right sides of the drawer 103 and the corresponding side walls of the first housing 102 to support the drawer 103 to slide in and out horizontally; at the same time, the first housing 102 directly constitutes at least part of the outer peripheral wall of the first body 100, so that the first body 100 formed by the first housing 102 is independently installed on the control panel of the clothing processing equipment, realizing the effect of the dispensing part 101 being separately set and independently installed.

[0064] Meanwhile, the first housing 102 is hollow inside, and the upper part of the hollow part is used for the installation of the drawer 103; the first housing 102 is also provided with a dispensing structure 105, which includes a dispensing water channel 5, a dispensing pump 4, a water passage 6, and a dispensing port 7; the dispensing water channel 5 is integrated on the upper cover 106 of the first housing 102, the inlet 13 of the dispensing water channel 5 is connected to the water inlet structure, the draw-out inlet 14 of the dispensing water channel 5 is connected to the dispensing pump 4, and the outlet 12 of the dispensing water channel 5 is connected to the interior of the first housing 102 and is oriented downwards. The drawer section 103 has a perforated section corresponding to the outlet 12 of the water inlet channel 5, so that the water inlet and the mixture of water inlet and laundry detergent flowing out of the outlet 12 of the water inlet channel 5 pass through the inlet section 101 and flow directly into the water passage section 6 below the drawer section 103; the lower part of the hollow part of the first housing 102 is provided with the water passage section 6, which is located below the drawer section 103, and the front side of the first housing 102 is provided with an inlet 7, which is connected to the water passage section 6 and is used to allow the mixture of water inlet and laundry detergent formed by the inlet section 101 to be dispensed outward.

[0065] like Figures 1 to 7As shown in the embodiment of this application, the first housing 102 is provided with a water-passing part 6, which is formed by the lower part of the hollow cavity inside the first housing 102; the drawer part 103 only covers part of the internal cavity of the first housing 102, and the other uncovered part forms a hollow part; the outlet 12 of the water-dispensing channel 5 integrated on the upper cover 106 of the first housing 102 is located on the bottom wall of the upper cover 106 and opens downwards, and the outlet 12 of the water-dispensing channel 5 is located above the hollow part, so that the laundry detergent flowing out of the water-dispensing channel 5 and the water-dispensing agent can pass through the water-dispensing channel 5. The water mixture flows directly into the water passage 6 below through the perforated part, and flows forward along the bottom wall of the first housing 102 to the inlet 7. The inlet 7 is located on the front side of the bottom wall of the first housing 102. The front side of the bottom wall of the first housing 102 is arc-shaped, and the gap between the arc and the front side panel of the drawer forms the downward-facing inlet 7. Optionally, in order to improve the water discharge effect, the bottom wall of the first housing 102 is set as a slope that gradually slopes downward from back to front, so as to ensure that the detergent and water mixture automatically flow out from the inlet 7 under the action of gravity.

[0066] like Figures 1 to 13 As shown in the embodiment of this application, the dispensing part 101 is provided with a liquid filling structure 104; the liquid filling structure 104 includes a liquid filling tank 1, which is disposed on the drawer part 103. The liquid filling tank 1 is provided with a liquid outlet 2, which is plugged into the liquid inlet end of the liquid filling connecting pipe 301; the liquid filling tank 1 is located on one side of the drawer part 103, so that the liquid filling tank 1 is located on the side close to the liquid storage part 201, so as to shorten the flow path of the liquid filling tank 1 for injecting the clothing treatment agent; at the same time, the liquid filling tank 1 is configured with an open top, which forms a liquid filling port 8, for the user to inject the clothing treatment agent into the liquid filling tank 1 after the drawer part 103 is pulled out, so that the injected clothing treatment agent flows into the liquid storage part 201 through the liquid filling connecting pipe 301 for storage, and is used for subsequent automatic extraction and dispensing; optionally, a cover plate 9 is installed on the liquid filling tank 1 of the drawer part 103, and the cover plate 9 can be flipped upward to open and close the liquid filling port 8.

[0067] Optionally, the liquid outlet 2 is located at the lowest point of the liquid filling tank 1, and is used to connect the lowest point of the liquid filling tank 1 to the liquid filling connecting pipe 301. In order to facilitate the connection between the liquid filling tank 1 and the liquid filling connecting pipe 301, the liquid outlet 2 is located at the bottom of the rear side wall of the liquid filling tank 1. The liquid outlet 2 extends from front to back, so that the liquid outlet 2 can be inserted into the liquid filling connecting pipe 301 in a front-to-back manner, so that the liquid outlet 2, the liquid filling connecting pipe 301 and the drawer 103 all extend in the front-to-back direction, so as to prevent the liquid filling connecting pipe 301 from bending due to the drawer 103 being pulled out, which would affect the flow of the injected clothing treatment agent towards the liquid storage section 201.

[0068] Furthermore, in order to further improve the flow of the added clothing treatment agent towards the storage section 201, the following configuration can be made: the bottom wall of the filling tank 1 is configured as a slope that gradually slopes downward from front to back, so that the clothing treatment agent injected into the filling tank 1 flows towards the liquid outlet 2 at the rear due to gravity, so that the injected clothing treatment agent can flow smoothly out of the filling tank 1 and enter the storage section 201 for storage.

[0069] Furthermore, in order to ensure that the laundry detergent injected into the filling tank 1 can flow smoothly into the storage section 201, the following configuration can be made: the filling connecting pipe 301 extends downward along the dispensing section 101 toward the storage section 201, or part of the filling connecting pipe 301 is horizontal and the other part extends downward in the connection direction to the storage section 201, so that the laundry detergent injected into the filling tank 1 automatically flows along the filling connecting pipe 301 toward the storage section 201 under the action of gravity, so that all the laundry detergent added at the drawer section 103 can enter the storage section 201.

[0070] like Figures 1 to 13 As shown in the embodiment of this application, the liquid filling connecting pipe 301 includes a telescopic pipe section 3, which can be axially telescopically deformed; the telescopic pipe section 3 is disposed in the first housing 102, and the telescopic pipe section 3 and the liquid outlet interface 2 of the liquid filling tank 1 are connected and interlocked; the telescopic pipe section 3 extends along a first orientation, which is parallel to the drawer 103's pull-out direction, and is used to provide synchronous telescopic deformation for the connected liquid filling connecting pipe 301 during the drawer 103's pull-out process; preferably, the liquid outlet interface 2 extends along the first orientation, so that the liquid outlet interface 2, which also extends along the drawer 103's pull-out direction, and the telescopic pipe section 3 are connected and interlocked, so that the telescopic pipe section 3 can only be telescopically deformed in the front-back direction, effectively avoiding the problem of the connecting pipe 300 bending and affecting the flow of the clothing treatment agent.

[0071] Optionally, the aforementioned telescopic tube section 3 can be a corrugated pipe with elastic telescopic corrugations on its wall. The elastic deformation generated by the corrugations on the corrugated pipe achieves the effect of axial elastic telescopic expansion and contraction of the telescopic tube section 3. Preferably, the telescopic tube section 3 can be configured to extend partially along the front and rear directions and communicate with the liquid outlet 2, partially bend, and partially extend laterally and pass through the first housing 102. This allows the telescopic tube section 3 with axial telescopic deformation to cover the bent and deflected portion of the connecting pipe 300. The deformation of the telescopic tube section 3 prevents folds from forming on the connecting pipe 300, thus preventing the clothing treatment agent from continuing to flow along the connecting pipe 300.

[0072] like Figures 1 to 13As shown in the embodiment of this application, the liquid storage unit 201 includes a second housing 202; the hollow space inside the second housing 202 is provided with at least one liquid storage cavity 203 for storing the clothing treatment agent; the liquid storage cavity 203 is connected to the liquid filling structure 104 of the dispensing unit 101 via a liquid filling connecting pipe 301; the liquid storage cavity 203 is connected to the dispensing structure 105 of the dispensing unit 101 via a dispensing connecting pipe 302.

[0073] In order to adapt the liquid storage section 201 to the control panel, the liquid storage section 201 can be set on the left or right side of the control panel, so that the shape of the second housing 202 of the liquid storage section 201 is set to an arc shape that is adapted to the control panel, so as to increase the capacity of the clothing treatment agent of the liquid storage section 201 while minimizing the space occupied by the liquid storage section 201.

[0074] Meanwhile, the bottom of the liquid storage chamber 203 inside the second housing 202 is connected to the liquid filling connection pipe 301 and the dispensing connection pipe 302 respectively, so that the laundry detergent entering the liquid storage chamber 203 through the liquid filling connection pipe 301 can flow smoothly into the liquid storage chamber 203, and the dispensing connection pipe 302 can extract the laundry detergent from the lowest point of the liquid storage chamber 203.

[0075] Furthermore, in order to ensure that all the laundry detergent in the storage chamber 203 can be extracted, the connection point between the dispensing connecting pipe 302 and the storage section 201 is located at the lowest point on one side of the storage chamber 203; and the bottom wall of the storage chamber 203 is set as an inclined or conical surface that gradually slopes downward toward the connection point of the dispensing connecting pipe 302, so that all the laundry detergent in the storage chamber 203 can flow to the dispensing connecting pipe 302 and then be extracted by the dispensing pump 4 to the dispensing section 101 for dispensing.

[0076] In addition, to ensure that the laundry detergent does not fail to fill the reservoir 203, the highest point of the reservoir 203 is generally lower than the opening of the filling tank 1. At the same time, to prevent the laundry detergent from overflowing from the opening of the filling tank 1, a maximum liquid level mark is marked inside the filling tank 1, and the maximum liquid level mark is level with the highest point of the reservoir 203.

[0077] like Figures 1 to 7As shown in the embodiment of this application, the dispensing structure 105 includes a dispensing pump 4 and a dispensing water path 5; the dispensing pump 4 connects the dispensing connecting pipe 302 and the dispensing water path 5, and is used to draw the laundry detergent in the storage chamber 203 to the dispensing water path 5; the dispensing water path 5 is provided on the upper cover 106 of the first housing 102, and is used to mix the introduced water flow and the extracted laundry detergent to form a laundry detergent mixture; the dispensing part 101 is also provided with a water passage 6 and a dispensing port 7, and the laundry detergent mixture flowing out of the dispensing water path 5 flows downward from the upper cover 106 to the water passage chamber, and then flows forward along the water passage chamber until it is dispensed outward into the outer cylinder of the laundry detergent device through the dispensing port 7, thereby achieving the effect of water entering the outer cylinder and automatically dispensing the laundry detergent mixture.

[0078] In this embodiment, the water inlet channel 5 is integrated into the upper cover 106 of the first housing 102. To achieve mixing of the incoming water and the extracted laundry detergent, a mixing structure can be installed on the water inlet channel 5 to form a laundry detergent mixture. This mixing structure can take any existing form, such as installing a rotatable impeller 11 in the water inlet channel 5, or providing a stop protrusion in the water inlet channel 5 to generate eddies in the flowing water, etc. Simultaneously, to prevent excessive liquid pressure in the water inlet channel 5, a [missing information - likely a design feature] can be provided near the outlet of the water inlet channel 5.

[0079] like Figures 1 to 13 As shown, the specific structure of the water inlet channel 5 can be as follows: The water inlet channel 5 is integrated into the upper cover 106 of the first housing 102. The inlet 13 of the water inlet channel 5 is located on the rear side and is connected to the water inlet pipe of the clothing treatment device through a controllable water inlet valve. The outlet 12 of the water inlet channel 5 is located in the middle, behind the drawer section 103 in the pushed-in state. The outlet 12 of the water inlet channel 5 is vertically opened downwards, corresponding to the water outlet to the water passage section 6 in the lower part of the first housing 102. The middle part of the water inlet channel 5 is provided with a suction inlet 14, which is connected to the outlet of the water inlet pump 4 so that the clothing treatment agent drawn by the water inlet pump 4 flows directly into the water inlet channel 5. At the same time, near the suction inlet 14, the water inlet channel 5 is provided with an impeller 11 that can rotate freely around an axis and is driven to rotate by the incoming water flow. The rotation of the impeller 11 mixes the incoming water and the drawn clothing treatment agent to form a clothing treatment agent mixture.

[0080] like Figures 1 to 13 As shown in the embodiment of this application, the outlet 12 of the water channel 5 of the clothing treatment agent dispensing device is provided with any of the above-mentioned foaming nozzle structures 15, and the inlet 158 ​​of the foaming mixing chamber 151 of the foaming nozzle structure 15 is connected to the water channel 5.

[0081] In this embodiment, the water inlet channel 5 is provided with a mixing chamber 501, and an impeller 11 is provided in the mixing chamber 501. The inlet water flowing through the mixing chamber 501 and the laundry detergent mixture drive the impeller 11 to rotate around its axis and stir, so that the inlet water and the laundry detergent are mixed to form a laundry detergent mixture. A strip-shaped liquid outlet is connected to one side of the mixing chamber 501. The outlet 12 of the water inlet channel 5 is located at the end of the strip-shaped liquid outlet. The foaming nozzle structure 15 is located on the lower side of the strip-shaped liquid outlet. The strip-shaped liquid outlet is connected to the water passage 6 below through the foaming nozzle structure 15, so that the laundry detergent mixture is foamed to form a foam-like laundry detergent mixture, which flows out of the water inlet channel 5, enters the water passage 6, and is discharged into the water tank through the dispensing port 7 provided on the first housing 102.

[0082] Furthermore, to prevent excessive pressure in the water dispensing channel 5, especially at the foaming nozzle structure 15, a pressure relief valve structure 16 is installed in the strip-shaped liquid outlet chamber 502. The pressure relief valve structure 16 is located between the foaming nozzle structure 15 and the foaming mixing chamber 151 to relieve pressure when excessive pressure occurs in the strip-shaped liquid outlet chamber 502, thus preventing problems such as inability to dispense water due to excessive pressure in the water dispensing channel 5. The pressure relief valve structure 16 can be any existing valve structure capable of releasing excessive pressure in the water dispensing channel 5, for example: The bottom wall of the strip-shaped liquid outlet chamber 502 of the water inlet channel 5 is provided with an upwardly protruding sleeve. The hollow interior of the sleeve connects the water inlet channel 5 and the lower water passage 6. A one-way valve plate is installed in the hollow space inside the sleeve. The upper side of the one-way valve plate is connected to the sleeve via a spring, so that the one-way valve plate is pulled upward under the action of the spring to close the closed position of the hollow channel inside the sleeve. When the pressure in the water inlet channel 5 is too high, the pressure difference is used to overcome the spring force and push the one-way valve plate downward to open the hollow channel inside the sleeve, so as to achieve the effect of depressurizing the water inlet channel 5.

[0083] In this embodiment, a first housing 102 has an outwardly pull-out drawer 103 installed inside; the upper cover 106 of the first housing 102 integrates the aforementioned water dispensing channel 5; a water passage 6 is provided inside the first housing 102, the water passage 6 is located below the drawer 103, and a dispensing port 7 is provided on the front side of the water passage 6; the foaming nozzle structure 15 is located on the lower side of the upper cover 106 and is staggered with the drawer 103, for dispensing the sprayed foam-like clothing treatment agent mixture outward through the dispensing port 7.

[0084] like Figures 1 to 13As shown in the embodiment of this application, the dispensing pump 4 is installed on the first body 100; for example, the dispensing pump 4 is fixedly installed on the right side wall of the first housing 102. Meanwhile, the dispensing pump 4 can also employ any other existing power unit structure, such as a negative pressure extraction unit, located on the dispensing water channel 5. It utilizes the water flowing through the dispensing water channel 5 to generate negative pressure suction, thereby using the negative pressure suction to extract the laundry detergent from the storage chamber 203 into the dispensing water channel 5.

[0085] In this embodiment, the drawer 103 is further provided with a manual dispensing section 10, which includes a manual dispensing trough with a siphon column. The user injects laundry detergent into the manual dispensing trough, where it is temporarily stored due to the siphon effect. The dispensing section 101 is also provided with a manual dispensing water passage 5, through which water flows into the manual dispensing trough. When the water level exceeds the siphon height of the siphon column, the water and the manually dispensed laundry detergent are drawn into the water passage 6 at the lower part of the first housing 102 by the siphon effect. The detergent is then dispensed outwards into the outer cylinder of the laundry treatment device through the dispensing port 7 at the front of the water passage 6. Optionally, a liquid filling tank 1 is provided on the right side of the drawer 103, and the manual dispensing section 10 is provided on the left side.
