[0053] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0054] When existing laundry treatment equipment washes clothes, washing substances such as laundry detergent are usually directly put into the laundry treatment cavity of the laundry treatment equipment, or the washing substances are put into the feeding assembly and then washed away by tap water. In this way, the washing substances cannot be fully dissolved and foamed, and the dissolution effect of the washing substances is not good, which will affect the washing degree of the laundry treatment equipment and the user experience.

[0055] The following refers to Figures 1 - 13 Describe the nozzle body assembly according to the embodiments of the present invention.

[0056] According to the nozzle body assembly 1 of the present utility model, it includes a housing 11, a drawer 12, and a foam generating device 13. The drawer 12 is movably arranged in the housing 11 and can optionally be moved to a first position located within the housing 11. A dosing chamber 121 is provided inside the drawer 12; the foam generating device 13 is arranged in the housing 11, and a liquid inlet 134 is formed on the foam generating device 13; wherein, the dosing chamber 121 is adapted to communicate with the liquid inlet 134 when the drawer 12 is in the first position.

[0057] The nozzle body assembly 1 of the present utility model is provided with a housing 11. The housing 11 is the frame structure of the nozzle body assembly 1. A drawer 12 is movably arranged inside the housing 11, that is, the drawer 12 is movable relative to the housing 11, so that the drawer 12 can leave the housing 11 through a pulling action or enter the housing 11 through a pushing action. A dosing chamber 121 for accommodating a washing substance is provided inside the drawer 12. When it is necessary to dose the washing substance, the drawer 12 can be pulled out of the housing 11 to complete the dosing; after the dosing is completed, the drawer 12 can be pushed back into the housing 11. The way the drawer 12 moves relative to the housing 11 facilitates operations such as dosing the washing substance by the user into the nozzle body assembly 1.

[0058] A foam generating device 13 is also arranged in the housing 11. The foam generating device 13 can foam the washing substance and generate foam before being used to clean the object to be washed, which can improve the washing effect of the nozzle body assembly 1. A liquid suction port is formed on the foam generating device 13. The drawer 12 can realize the conduction relationship between the dosing chamber 121 and the foam generating device 13 by changing its relative position with respect to the housing 11. Specifically, when the drawer 12 moves in the housing 11, it has a first position. When the drawer 12 moves to the first position, the dosing chamber 121 is in communication with the foam generating device 13 through the liquid inlet 134; when the drawer 12 is in other positions, the dosing chamber 121 and the liquid inlet 134 are in a non-conductive state. At this time, the dosing chamber 121 and the foam generating device 13 are in a non-conductive state.

[0059] When the drawer 12 is in the first position, such as Figure 1 the position of the drawer 12 shown at this time can be understood as the first position. At this time, that is, the dosing chamber 121 is in communication with the foam generating device 13. The washing substance in the dosing chamber 121 can enter the foam generating device 13 through the liquid inlet 134 and be foamed. The setting of the foam generating device 13 enables the washing substance sucked out from the dosing chamber 121 to be mixed with air and water to generate foam. Compared with directly spraying the washing substance onto the surface of the object to be washed, the setting of the foam generating device 13 can improve the dissolution effect of the washing substance, make the washing substance foam, and the foamed washing substance can better cover the surface of the clothes, improve the washing effect of the clothes treatment equipment, and at the same time reduce the waste of the washing substance and improve the utilization rate of the washing substance.

[0060] Through the movable design of the drawer 12 of the nozzle body assembly 1, the user can directly place washing substances such as detergents into the dosing chamber 121 inside the drawer 12. When the drawer 12 moves to the first position inside the housing 11, the dosing chamber 121 communicates with the liquid suction port of the foam generating device 13, thus realizing the automatic dosing of the washing substances, simplifying the user's operation steps, improving the convenience of use. The washing substances enter the foam generating device 13, foam, and then flow out from the liquid outlet end 112 for cleaning the object to be washed, improving the cleaning effect of the nozzle body assembly 1.

[0061] In some embodiments, the washing substances may be detergents, fabric conditioners, fungicides, or other functional preparations for cleaning, etc.

[0062] According to an embodiment of the present invention, as Figure 1 and 7 shown, a temporary storage chamber 114 is formed inside the housing 11 and is open towards the drawer 12. The temporary storage chamber 114 communicates with the liquid inlet 134 and can selectively communicate with the dosing chamber 121. The temporary storage chamber 114 can be simply understood as a temporary storage area for the washing substances before flowing into the foam generating device 13. An opening can be made on the bottom wall of the temporary storage chamber 114 to communicate with the liquid inlet 134, so that the washing substances entering the temporary storage chamber 114 can enter the foam generating device 13 from the bottom of the temporary storage chamber 114 of the housing 11, avoiding the residue of the washing substances in the temporary storage chamber 114. The temporary storage chamber 114 is open towards the drawer 12. When the drawer 12 moves to the first position, the washing substances can directly enter the temporary storage chamber 114 without passing through other guiding pipeline structures, which can reduce the unnecessary structures inside the nozzle body assembly 1 and improve the compactness of the nozzle body assembly 1. The setting of the temporary storage chamber 114 enables the washing substances to have a buffering process before entering the foam generating device 13, making the flow rate of the washing substances entering the foam generating device 13 more uniform and facilitating the foaming of the washing substances in the foam generating device 13.

[0063] According to an embodiment of the present utility model, the nozzle body assembly 1 further includes: a closing member disposed in the drawer 12, and the closing member is adapted to communicate the dispensing chamber 121 with the temporary storage chamber 114 when the drawer 12 is in the first position. The arrangement of the closing member makes the communication between the dispensing chamber 121 and the temporary storage chamber 114 controllable. When the drawer 12 is in the first position, the closing member can communicate the dispensing chamber 121 with the temporary storage chamber 114, and the washing substance in the dispensing chamber 121 can enter the temporary storage chamber 114. The flow of the washing substance can be precisely controlled through the closing member. Specifically, when the drawer is not moved to the first position, the closing member can be in a closed state, effectively preventing the leakage of the washing substance from the dispensing chamber 121; when the foam generating device 13 needs the washing substance, the closing member opens and controls the communication between the dispensing chamber 121 and the temporary storage chamber 114, and the washing substance can flow through the temporary storage chamber 114 and then enter the foam generating device 13. The arrangement of the closing member enables the nozzle body assembly 1 to control the flow of the washing substance in the dispensing chamber 121, that is, only when the drawer 12 is in the first position, the washing substance in the dispensing chamber 121 can enter the foam generating device 13 through the temporary storage chamber 114, and when the drawer 12 is in other positions, the closing member is in a closed state, avoiding the leakage problem of the washing substance.

[0064] According to an embodiment of the present utility model, as Figure 1 shown, a liquid outlet 122 is provided on the side of the dispensing chamber 121 facing the temporary storage chamber 114, and the closing member includes a baffle 123 which is movably disposed at the liquid outlet 122 and selectively conducts or closes the liquid outlet 122. Since the closing member is a key structure for communicating the dispensing chamber 121 and the temporary storage chamber 114, the structure of the closing member will affect the flow of the washing substance in the dispensing chamber 121 towards the temporary storage chamber 114. Specifically, a liquid outlet 122 is provided on the side of the dispensing chamber 121 facing the open side of the temporary storage chamber 114, and the closing member is configured as a baffle 123 rotatably disposed at the liquid outlet 122. When the drawer 12 is moved to the first position, the baffle 123 can rotate to open the liquid outlet 122. At this time, the washing substance in the dispensing chamber 121 can flow into the temporary storage chamber 114 through the liquid outlet 122; when the drawer 12 is not moved to the first position, the baffle 123 will not rotate. At this time, the baffle 123 closes the liquid outlet 122, and the washing substance in the dispensing chamber 121 cannot flow into the temporary storage chamber 114. By controlling the rotation of the baffle 123, the flow of the washing substance in the dispensing chamber 121 can be controlled. For example, when the drawer 12 is moved to the first position, the baffle 123 can rotate, and the washing substance in the dispensing chamber 121 can enter the foam generating device 13; when the drawer 12 is in other positions, the baffle 123 will not rotate, and the washing substance in the dispensing chamber 121 cannot flow out, reducing the leakage of the washing substance.

[0065] According to an embodiment of the present utility model, as Figure 1and 7 As shown in 7 , the nozzle body assembly 1 further includes a door-opening post 1141. The door-opening post 1141 is disposed on the side wall of the temporary storage chamber 114 and extends toward the baffle 123. The door-opening post 1141 is adapted to push the baffle 123 to rotate to open the liquid outlet 122 when the drawer 12 is in the first position.

[0066] The door-opening post 1141 can be simply understood as a driving device for driving the baffle 123 to rotate. The door-opening post 1141 is disposed on the side wall of the temporary storage chamber 114 and extends toward the baffle 123. When the drawer 12 moves to the first position, the baffle 123 contacts the door-opening post 1141 and is pushed open by the door-opening post 1141 by a certain angle. It can also be understood that during at least part of the process when the drawer 12 moves to the first position, after the baffle 123 contacts the door-opening post 1141, it will rotate by a certain angle under the action of the door-opening post 1141 to realize the rotation of the baffle 123 to open the liquid outlet 122. The setting of the door-opening post 1141 makes the rotation of the baffle 123 more automated, simplifies the operation process of opening the liquid outlet 122, and enables the washing substance in the dosing chamber 121 to flow into the temporary storage chamber 114 without manual operation, improving the automation degree of the nozzle body assembly 1 and the convenience during use.

[0067] According to an embodiment of the present invention, a water inlet end 111 and a liquid outlet end 112 are provided on the housing 11. The housing 11 forms a first water passage that communicates the water inlet end 111 with the liquid outlet end 112, and the foam generating device 13 is disposed in the first water passage.

[0068] The liquid outlet end 112 and the water inlet end 111 are provided on the housing 11. The water inlet end 111 communicates the external water source with the housing 11 to facilitate introducing the external water source into the housing 11, and the liquid outlet end 112 can be understood as the overall outlet of the nozzle body assembly 1. A first water passage that communicates the water inlet end 111 with the liquid outlet end and passes through the foam generating device 13 is formed in the housing 11. Among them, the inlet of the foam generating device 13 is communicated with the inlet of the first water passage, and the outlet of the foam generating device 13 is communicated with the outlet of the first water passage. The water introduced by the water inlet end 111 can enter the foam generating device 13 after being guided by at least part of the first water passage. The water entering the foam generating device 13 can be mixed with the washing substance entering the foam generating device 13 through the liquid inlet 134 to generate foam and a large amount of foam. The mixed liquid mixed with foam flows out through the outlet of the foam generating device 13, then flows toward the liquid outlet end 112 and finally flows out of the nozzle body assembly 1 through the liquid outlet end 112 for cleaning the object to be washed. The cooperation of the first water passage and the foam generating device 13 can make the mixed liquid of the washing substance generate foam, thereby improving the washing effect of the nozzle body assembly 1.

[0069] According to an embodiment of the present utility model, the foam generating device 13 includes: a first section 131 and a second section 132. One end of the first section 131 is communicated with the water inlet end 111; one end of the second section 132 is communicated with the other end of the first section 131, and the other end of the second section 132 is communicated with the liquid outlet end 112. A liquid inlet 134 is provided on the second section 132; wherein, the diameter of the second section 132 is smaller than that of the first section 131.

[0070] Since the foam generating device 13 is a structure for guiding the foaming of the washing substance, the structure of the foam generating device 13 will affect the foaming effect. Specifically, the foam generating device 13 is provided with a first section 131 and a second section 132 connected to each other. Among them, the first section 131 is communicated with the water inlet end 111; the second section 132 communicates the first section 131 with the liquid outlet end 112, and a liquid inlet 134 communicated with the temporary storage chamber 114 is provided on the second section 132. When the drawer 12 moves to the first position, the washing substance in the dosing chamber 121 flows into the temporary storage and enters the second section 132 through the liquid inlet 134. The washing substance entering the second section 132 can be mixed with the water introduced by the first section 131 and foam. During this process, since the diameter of the first section 131 is larger than that of the second section 132, the flow rate of the mixed liquid in the second section 132 will increase and foam will be generated. Since the foam has better covering and permeability, compared with directly putting the washing substance into the object to be washed, the same amount of washing substance in the foam generating device 13 can generate more foam, thereby improving the washing effect of the laundry treatment device.

[0071] According to an embodiment of the present utility model, the foam generating device 13 further includes a third section 133. One end of the third section 133 is communicated with the other end of the second section 132, and the other end of the third section 133 is communicated with the liquid outlet end 112. The diameter of the second section 132 is smaller than that of the third section 133. By providing the third section 133, the foam mixed liquid in the second section 132 can be buffered in the third section 133 before flowing to the liquid outlet end 112. Since the diameter of the third section 133 is larger than that of the second section 132, the flow rate of the mixed liquid in the third section 133 is less than the flow rate of the mixed liquid in the second section 132. At this time, the foam in the foam mixed liquid can have more time and space to grow and stabilize, and more persistent and stable foam can be formed, improving the foam quality and reducing the possibility of the foam breaking during the flow process, thereby ensuring the washing effect of the nozzle body assembly 1.

[0072] According to an embodiment of the present utility model, an air inlet 135 is further provided on the second section 132. The air inlet 135 communicates the foam generating device 13 with the outside, and the air inlet 135 and the liquid inlet 134 are at least partially opposite in the radial direction of the second section 132. Since the diameter of the second section 132 is smaller than the diameters of the first section 131 and the third section 133, the flow rate of the mixed liquid in the second section 132 is relatively fast, so that a low-pressure area can be formed in the second section 132. At this time, by providing the air inlet 135 on the second section 132, external air can be actively introduced into the foam generating device 13. The air entering the second section 132 is mixed with the mixed liquid to form a gas-liquid mixture, thereby generating rich foam, improving the foaming efficiency of the foam generating device 13. At the same time, the air entering the foam can improve the stability of the foam and improve the foaming quality of the foam generating device 13.

[0073] In addition, the air inlet 135 and the liquid inlet 134 can be at least partially opposite. Since the air inlet 135 and the liquid inlet 134 are at least partially opposite in the radial direction of the second section 132, when the washing substance flows through the liquid inlet 134 and enters the second section 132, external air can directly enter the second section 132 through the air inlet 135. The air and the washing substance enter the second section 132 at the same time, ensuring that the air and the mixed liquid can be fully contacted and mixed in the foam generating device 13, thereby generating more and more stable foam.

[0074] According to an embodiment of the present utility model, the first waterway includes: a water inlet channel 115. The inlet of the water inlet channel 115 is communicated with the water inlet end 111, and the outlet of the water inlet channel 115 is communicated with one end of the first section 131. The water inlet channel 115 and the temporary storage cavity 114 are arranged at intervals in the moving direction of the drawer 12.

[0075] Specifically, a section between the water inlet end 111 and the inlet of the foam generating device 13 of the first waterway can be understood as the water inlet channel 115. In terms of layout, the water inlet channel 115 and the temporary storage cavity 114 are arranged at intervals in the moving direction of the drawer 12. It can also be understood that in the moving direction of the drawer 12, there are successively a feeding cavity 121, a temporary storage cavity 114, and a water inlet channel 115. The layout of the water inlet channel 115 improves the compactness of the structure of the nozzle body assembly 1. At the same time, the water inlet channel 115 is located on the side of the temporary storage cavity 114 away from the drawer 12, which can avoid the influence of the movement of the drawer 12 on the water flow in the water inlet channel 115, avoid water flow fluctuations or interruptions, and ensure the continuity and stability of the water flow entering the foam generating device 13 from the water inlet channel 115, thereby ensuring the continuous generation of foam.

[0076] According to an embodiment of the present utility model, the nozzle body assembly 1 further includes: a second waterway 16, which is arranged on the upper surface of the housing 11 and is spaced from at least part of the water inlet passage 115. The inlet of the second waterway 16 is communicated with the water inlet end 111, and the outlet of the second waterway 16 is communicated with the dosing chamber 121. Specifically, a second waterway 16 is also arranged on the nozzle body assembly 1, and the second waterway 16 also communicates the water inlet end 111 and the liquid outlet end 112. Different from the first waterway flowing through the foam generating device 13, the second waterway 16 flows through the dosing chamber 121. A part of the water entering from the water inlet end 111 can directly flow into the dosing chamber 121 through the second flow path. The water entering the dosing chamber 121 can overflow from at least part of the side wall of the dosing chamber 121 and flow towards the liquid outlet end 112. Different from the first waterway, there is no foam generating device 13 in the second waterway 16. The water and the washing substance in the second waterway 16 are directly mixed in the dosing chamber 121 and used to clean the object to be washed. The cleaning method of the second waterway 16 is applicable to the case where the stains on the object to be washed are less. Such a cleaning method can further simplify the operation process on the premise of meeting the cleaning requirements.

[0077] In addition, the second waterway 16 is arranged on the surface of the housing 11 and is spaced from at least part of the water inlet passage 115, so that the arrangement of the first waterway and the second waterway 16 in the housing 11 is more compact, the volume of the nozzle body assembly 1 can be reduced, and it is convenient to arrange the nozzle body assembly 1.

[0078] According to an embodiment of the present utility model, a plurality of water inlet holes 161 communicating with the dosing chamber 121 are arranged at intervals in the extending direction of the second waterway 16, and the plurality of water inlet holes 161 are configured as the outlet of the second waterway 16. Specifically, a plurality of spaced-apart water inlet holes 161 are arranged on the upper surface of the housing 11 of the second waterway 16, and each water inlet hole 161 is respectively communicated with the dosing chamber 121. As Figure 9 shown, the arrangement of the plurality of water inlet holes 161 enables the water in the second waterway 16 to enter the dosing chamber 121 from multiple different positions, improving the rate of water entering the dosing chamber 121. At the same time, when the water in the second waterway 16 enters the dosing chamber 121 from the plurality of water inlet holes 161, it can impact the washing substance in the dosing chamber 121 and mix the washing substance with the water to generate foam, which can increase the foam content of the mixed liquid overflowing from the dosing chamber 121 and improve the washing effect of the mixed liquid flowing from the second waterway 16 to the dosing chamber 121 and flowing out through the liquid outlet end 112.

[0079] In some embodiments, the first waterway and the second waterway 16 can have water flowing simultaneously. For example, on-off valves can be respectively installed at the connection positions between the water inlet end 111 and the first waterway and between the water inlet end 111 and the second waterway 16. Through the on-off valves, the on or off states of the first waterway and the second waterway 16 can be selectively controlled. The design of the on-off valves can provide different choices for the liquid discharge of the nozzle body assembly 1. For example, it can be selected to respectively conduct or simultaneously conduct the first waterway and the second waterway 16. Different choices result in different washing effects of the nozzle body assembly 1, and appropriate methods can be correspondingly selected according to the washing requirements, improving the flexibility and controllability of the nozzle body assembly 1.

[0080] According to an embodiment of the present invention, the housing 11 includes: an outer shell 116, an inner shell 117, and a baffle 118. An accommodation cavity 113 is formed inside the outer shell 116; the inner shell 117 is disposed inside the accommodation cavity 113 and defines a water outlet cavity 1171 that opens towards the liquid outlet end 112. The other end of the third section 133 extends into the water outlet cavity 1171 and communicates with the water outlet cavity 1171; the baffle 118 is disposed at the open end of the water outlet cavity 1171 and is used to block the mixed liquid led out from the water outlet cavity 1171.

[0081] As Figure 7 shown, the housing 11 can be divided into the outer shell 116 and the inner shell 117. Among them, an accommodation cavity 113 for accommodating the drawer 12 is formed inside the outer shell 116; the inner shell 117 is disposed inside the accommodation cavity 113. In Figure 7 it can be understood that the inner shell 117 is disposed on the bottom wall of the accommodation cavity 113. The inner shell 117 defines a water outlet cavity 1171 inside the accommodation cavity 113 that opens towards the liquid outlet end 112 and communicates with the liquid outlet end 112. The outlet of the third section 133 is located inside the water outlet cavity 1171. Therefore, the mixed liquid flowing out of the third section 133 first flows into the water outlet cavity 1171 and then reaches the liquid outlet end 112. A baffle 118 is disposed at the open end of the water outlet cavity 1171. The baffle 118 closes at least part of the open end of the water outlet cavity 1171. Therefore, the foam mixed liquid inside the water outlet cavity 1171 needs to overflow from the upper part of the baffle 118. The water outlet cavity 1171 can be simply understood as a space area for temporarily storing the mixed liquid. The speed of the foam mixed liquid flowing out of the third section 133 is fast, and the water outlet cavity 1171 can buffer the foam mixed liquid, reducing the possibility of the foam bursting to ensure the washing effect of the final mixed liquid.

[0082] In some embodiments, the accommodation cavity 113 can extend in the front-rear direction. Here, the front-rear direction can also be understood as the moving direction of the drawer 12, and the temporary storage cavity 114 is disposed at the rear side of the accommodation cavity 113. Such a layout design can improve the structural compactness of the nozzle body assembly 1 and at the same time make the on state more stable when the dosing cavity 121 and the temporary storage cavity 114 are in communication.

[0083] According to an embodiment of the present invention, first mating portions 1172 are provided on both sides of the inner shell 117 in the width direction. The baffle 118 includes a plate body 1181 and second mating portions 1182. The plate body 1181 extends in the width direction of the inner shell 117 to close the open mouth of at least a part of the water outlet cavity 1171; the second mating portions 1182 are provided at both ends of the plate body 1181 in the extending direction and are adapted to cooperate with the first mating portions 1172.

[0084] As Figure 5 、 Figure 7 and Figure 11 shown, the main body portion of the baffle 118 is configured as the plate body 1181. Second mating portions 1182 are provided at both ends of the plate body 1181 in the width direction shown in Figure 7 . Correspondingly, first mating portions 1172 are provided on two side walls of the inner shell 117 in the width direction. The first mating portions 1172 can cooperate with the second mating portions 1182 to achieve the assembly and fixation of the baffle 118, ensuring the stability of the baffle 118 after being assembled to the open mouth of the inner shell 117.

[0085] In some embodiments, the first mating portion 1172 is configured as a mounting hole, and the second mating portion 1182 is configured as a mounting protrusion that can extend into the mounting hole. During assembly, the mounting protrusion can be received in the mounting hole, and the side surface of the mounting protrusion can abut against the side wall of the mounting hole, further improving the stability of the assembly of the baffle 118.

[0086] In some embodiments, as Figure 12 shown, a guiding inclined surface 11821 can be machined on the second mating portion 1182. The guiding inclined surface 11821 can guide the cooperation between the first mating portion 1172 and the second mating portion 1182, improving the assembly efficiency of the baffle 118.

[0087] According to an embodiment of the present invention, a first limiting portion 1173 is provided on the inner shell 117, and a second limiting portion 1183 adapted to be in limiting cooperation with the first limiting portion 1173 is provided on the plate body 1181. Since the function of the baffle 118 is to block the foam mixture in the water outlet cavity 1171 and change the flow direction of the foam mixture, the baffle 118 cannot rotate. Specifically, the first limiting portion 1173 is provided on the inner shell 117, and the second limiting portion 1183 is provided at the top of the plate body 1181. It can also be understood that the second limiting portions 1183 protrude towards each other and abut. After the baffle 118 and the inner shell 117 are assembled, the first limiting portion 1173 and the second limiting portion 1183 are in limiting cooperation, restricting the rotation of the baffle 118 in the Figure 11 clockwise direction shown in the baffle 118, enabling the baffle 118 to achieve the flow blocking effect.

[0088] According to an embodiment of the present utility model, the first limiting portion 1173 is disposed on the inner shell 117 and extends toward the baffle 118, and a stop surface 1174 is formed at one end of the first limiting portion 1173 facing the baffle 118; the second limiting portion 1183 is disposed at one end of the plate body 1181 in the height direction of the nozzle body assembly 1 and extends toward the first limiting portion 1173, and the second limiting portion 1183 is adapted to abut against the stop surface 1174.

[0089] As Figure 7 shown, a stop surface 1174 is formed at one end of the first limiting portion 1173 facing the second limiting portion 1183. When the baffle 118 is fixed, the second limiting portion 1183 abuts against the stop surface 1174. The setting of the stop surface 1174 can increase the mating area when the first limiting portion 1173 and the second limiting portion 1183 abut, thereby improving the stability when the first limiting portion 1173 and the second limiting portion 1183 abut.

[0090] According to an embodiment of the present utility model, a third limiting portion 1184 is disposed at the other end of the plate body 1181 in the height direction of the nozzle body assembly 1, and the third limiting portion 1184 extends toward the liquid outlet end 112 to limit the rotation of the baffle 118. As Figure 7 and Figure 11 shown, a second limiting portion 1183 is disposed at one end of the plate body 1181 in the height direction, and a third limiting portion 1184 is disposed at the other end. The third limiting portion 1184 extends in a direction away from the water outlet cavity 1171. When the baffle 118 is assembled, the third limiting portion 1184 can abut against the bottom wall of the accommodating cavity 113 to limit the rotation of the baffle 118 in the counterclockwise direction as Figure 11 shown, facilitating the baffle 118 to block the foam mixture in the water outlet cavity 1171.

[0091] According to an embodiment of the present utility model, a first converging plate 141 and a second converging plate 142 extending toward each other are respectively disposed on both sides of the water outlet cavity 1171 in the width direction. A converging area 143 is defined between the first converging plate 141 and the second converging plate 142, and the outlet of the converging area 143 is communicated with the liquid outlet end 112.

[0092] As Figure 9As shown, a first confluence plate 141 and a second confluence plate 142 are respectively arranged on both sides of the water outlet cavity 1171 in the width direction. The first confluence plate 141 and the second confluence plate 142 face each other and define a confluence area 143. The mixed liquid overflowing in the feeding cavity 121, the foam mixed liquid flowing out of the water outlet cavity 1171, or the mixed liquid flowing out of other positions in the housing 11 can all converge in the confluence area 143. By defining the confluence area 143, the convergence of the mixed liquid can be controlled, so that the mixed liquid finally flowing out of the liquid outlet end 112 can more evenly cover the object to be washed or the specific area to be cleaned, and the poor cleaning effect or waste of resources caused by uneven distribution of the mixed liquid can be avoided.

[0093] In addition, the first confluence plate 141 and the second confluence plate 142 can also increase the structural strength of the nozzle body assembly 1 and reduce the wear caused by the impact of water flow and mixed liquid.

[0094] The laundry treatment device according to the present utility model will be briefly described below.

[0095] The laundry treatment device according to the present utility model includes the nozzle body assembly 1 in the above-mentioned embodiment. Since the laundry treatment device according to the present utility model is provided with the nozzle body assembly 1 in the above-mentioned embodiment, when the laundry treatment device is in use, the user only needs to put the washing substance into the feeding cavity 121 of the drawer 12 and control the drawer 12 to move to the first position. At this time, the washing substance can automatically enter the foam generating device 13 and generate foam. The mixed liquid containing foam flows into the laundry treatment cavity of the laundry treatment device through the liquid outlet end 112 for cleaning clothes, improving the utilization rate of the washing substance, and further improving the washing effect and user experience of the laundry treatment device.

[0096] In some embodiments, a workbench can be arranged on the laundry treatment device. During assembly, the nozzle body assembly 1 can be assembled to the workbench. The arrangement of the workbench can integrate the nozzle body assembly 1 and the operation unit of the laundry treatment device into the same structure, which is convenient for the user to operate.

[0097] In some embodiments, the diameter of the second section 132 is d1, and the diameter of the liquid inlet 134 is d2, and the following is satisfied: 0.4 ≤ d2 / d1 ≤ 0.45. Since the liquid inlet 134 is provided on the second section 132, the dimensional relationship between the liquid inlet 134 and the second section 132 will affect the generation of foam. Specifically, if the diameter of the second section 132 is d1 and the diameter of the liquid inlet 134 is d2, then the following is satisfied: 0.4 ≤ d2 / d1 ≤ 0.45. Among them, when d2 / d1 < 0.4, the diameter of the liquid inlet 134 is relatively small compared to the diameter of the second section 132. At this time, the amount of the washing substance entering the main flow path through the liquid inlet 134 is small, which will cause a shortage of the washing substance in the main flow path, reduce the generated foam, and further lead to a decline in the washing effect; when d2 / d1 > 0.45, the diameter of the liquid inlet 134 is relatively large compared to the diameter of the second section 132. At this time, the amount of the washing substance entering the main flow path through the liquid inlet 134 is large, which will cause an excessive amount of the washing substance in the main flow path. Due to the limited size of the main flow path, the excessive washing substance cannot be foamed in time before flowing out of the foam generating device 13, thus leading to a reduction in the washing effect. Therefore, the ratio of the diameter of the liquid inlet 134 to the diameter of the second section 132 should be within a relatively appropriate range. For example, d2 / d1 is preferably 0.43. When d2 / d1 = 0.43, the foaming effect is better than other values.

[0098] In some embodiments, 2.5 mm ≤ d1 ≤ 3.5 mm. Since the size of d1 will affect the flow rates of the washing substance and water in the second section 132, d1 needs to be maintained within a suitable range. Specifically, when d1 < 2.5 mm, the diameter of the second section 132 is too small. At this time, the flow rates of the washing substance and water in the second section 132 are too fast, and it is difficult for the washing substance and water to be fully mixed. The foam generating device 13 generates less foam, which will cause a reduction in the cleaning effect of the foam generating device 13; when d1 > 3.5 mm, the diameter of the liquid inlet 134 is too large. At this time, the flow rates of the washing substance and water in the second section 132 are too slow. Due to the low flow rate and small impact force of the fully mixed liquid mixture, the generated foam is also relatively small. Therefore, 2.5 mm ≤ d1 ≤ 3.5 mm is a relatively appropriate range. Within this range, d1 can be preferably 3 mm.

[0099] In some embodiments, 1 mm ≤ d2 ≤ 1.5 mm. Since the size of d2 affects the entry of the washing substance into the second section 132, d2 needs to be maintained within a suitable range. Specifically, when d2 < 1 mm, the diameter of the liquid inlet 134 is too small. At this time, the rate of the washing substance entering the second section 132 is low, and the amount of foam generated by the foam generating device 13 is small, resulting in a reduction in the cleaning effect of the foam generating device 13; when d2 > 1.5 mm, the diameter of the liquid inlet 134 is too large. At this time, the efficiency of the washing substance entering the second section 132 is too fast, and too much washing substance enters the foam generating device 13, causing waste of the washing substance and increasing the cost. Therefore, 1 mm ≤ d2 ≤ 1.5 mm is a relatively suitable range, and within this range, d2 can preferably be 1.3 mm.

[0100] In some embodiments, if the diameter of the second section 132 is d1 and the diameter of the air inlet 135 is d3, then 0.45 ≤ d3 / d1 ≤ 0.55 is satisfied. Since the air inlet 135 is provided on the second section 132, the dimensional relationship between the air inlet 135 and the second section 132 affects the generation of foam. Specifically, if the diameter of the second section 132 is d1 and the diameter of the air inlet 135 is d3, then 0.45 ≤ d3 / d1 ≤ 0.55 is satisfied. Among them, when d3 / d1 < 0.45, the diameter of the air inlet 135 is relatively small compared to the diameter of the second section 132. At this time, the amount of air entering the foam generating device 13 through the air inlet 135 is small, resulting in insufficient gas mixed with the mixed liquid in the foam generating device 13, reducing the quality and quantity of the generated foam, and further leading to a decline in the washing effect; when d3 / d1 > 0.55, the diameter of the air inlet 135 is relatively large compared to the diameter of the second section 132. At this time, the oversized air inlet 135 easily causes the mixed liquid to leak from the air inlet 135. Therefore, the ratio of the diameter of the air inlet 135 to the diameter of the second section 132 should be within a relatively suitable range. For example, d3 / d1 is preferably 0.5. When d3 / d1 = 0.5, while ensuring the sealing performance, the foaming effect is better than other values.

[0101] In some embodiments, 1.2 mm ≤ d3 ≤ 2 mm. Since the diameter of the air inlet 135 affects the entry of air into the foam generating device 13, the diameter of the air inlet 135 needs to be set within a suitable range. Specifically, when d3 < 1.2 mm, the diameter of the air inlet 135 is too small. At this time, the rate of air entering the second section 132 is low, and without the intervention of air, the amount of foam generated by the foam generating device 13 is small, resulting in a reduction in the cleaning effect of the foam generating device 13; when d3 > 2 mm, the diameter of the air inlet 135 is too large. At this time, the washing substance and water easily leak from the air inlet 135. Therefore, 1.2 mm ≤ d3 ≤ 2 mm is a relatively suitable range, and within this range, d3 can preferably be 1.3 mm.

[0102] In some embodiments, if the diameter of the second section 132 is d1, and the diameters of the first section 131 and the third section 133 can both be d4, then 0.35 ≤ d1 / d4 ≤ 0.45 is satisfied. Since the second section 132 is disposed between the first section 131 and the third section 133, and the second section 132 is configured as a variable-diameter section, the relationship between the diameter of the second section 132 and the diameter of the third section 133 will affect the foaming effect of the mixed liquid in the foam generating device 13. When d1 / d4 < 0.35, the second section 132 is too small compared to the third section 133. At this time, the flow rate in the second section 132 is too fast, and the washing substances and water entering the second section 132 cannot be mixed completely in time, resulting in a reduction in the finally generated foam. When d1 / d4 > 0.45, the second section 132 is too large compared to the third section 133. At this time, the change in the flow rate between the second section 132 and the third section 133 is very small. Since the change in the flow rate on the flow path is small, the washing substances and water are fully mixed, resulting in a relatively stable mixed liquid, and thus less foam is generated. Therefore, 0.35 ≤ d1 / d4 ≤ 0.45 is a more suitable range, and within this range, d1 / d4 = 0.4 can be preferably selected. It should be noted that the diameters of the first section 131 and the third section 133 can be the same.

[0103] In some embodiments, a sink 1213 is formed on the bottom wall of the dosing chamber 121, and a siphon device 15 can be disposed in the sink 1213, such as Figure 8 and Figure 10 shown. The outlet of the siphon device 15 is communicated with the confluence area 143. The siphon device 15 can discharge the residual washing substances in the dosing chamber 121 and the water introduced into the dosing chamber 121 through the second waterway 16 by siphon, and is used for washing clothes, avoiding the residue of the washing substances and water in the dosing chamber 121, and effectively avoiding the problem of secondary pollution of the dosing chamber 121 caused by the residual substances. In this process, the purpose of designing the sink 1213 is to improve the ability of the siphon device 15 to siphon the residual washing substances and water in the dosing chamber 121.

[0104] In some embodiments, as Figure 10 shown, the siphon device 15 includes: a siphon tube 151 and a siphon cylinder 152. The siphon tube 151 is disposed on the bottom wall of the sink 1213, and a first siphon water path 1511 communicating the dosing chamber 121 with the confluence area 143 is formed in the siphon tube 151; the siphon cylinder 152 covers at least a part of the outer periphery of the siphon tube 151, and a second siphon water path 1521 is formed between the siphon cylinder 152 and the siphon tube 151; wherein, a siphon gap 153 communicating the dosing chamber 121 with the second siphon water path 1521 is left between the siphon cylinder 152 and the bottom wall of the sink 1213.

[0105] Specifically, the siphon 151 is disposed on the bottom wall of the sink 1213, and the siphon cylinder 152 is sleeved on the outer periphery of the siphon 151 to facilitate the formation of a siphon gap 153 at the bottom wall position of the sink 1213. The residual water and washing substances in the dosing chamber 121 can pass through the siphon gap 153, sequentially pass through the second siphon water path 1521 and the first siphon water path 1511, and then flow into the confluence area 143. The installation position and the internal structure of the siphon device 15 ensure that the siphon device 15 can remove the residues at the bottom of the dosing chamber 121, improving the siphon effect.

[0106] In some embodiments, a water outlet 1214 is formed on at least a part of the side wall of the dosing chamber 121. It can also be simply understood that at least one side wall of the dosing chamber 121 is lower than the adjacent side wall to form the water outlet 1214. After the water in the first water path enters the dosing chamber 121 and is mixed with the washing substances, it can directly overflow to the confluence area 143 through the water outlet 1214.

[0107] In some embodiments, the dosing chamber 121 includes a first chamber 1211 and a second chamber 1212. The first chamber 1211 and the second chamber 1212 respectively connect the water inlet end 111 and the liquid outlet end 112. The first chamber 1211 and the second chamber 1212 can be used to accommodate different washing substances, such as detergents and disinfectants.

[0108] In some embodiments, the dosing assembly further provides a marking plate 17 extending towards the inside of the dosing chamber 121 on the siphon cylinder 152. A scale marking 171 is provided on the marking plate 17. The position of the scale marking 171 is not higher than the lowest side wall of the dosing chamber 121, or the scale marking 171 is not higher than the standardized maximum height for dosing washing substances in the dosing chamber 121. When the user doses the washing substances, the scale marking 171 can be used to intuitively judge whether the amount of the dosed washing substances is appropriate, avoiding the situation where too much washing substances flow out directly from the side wall of the dosing chamber 121 and affecting the washing effect. The setting of the scale marking 171 can improve the user experience.

[0109] In summary, the nozzle body assembly 1 is provided with an inner shell 117 and an outer shell 116. An accommodation cavity 113 is formed inside the outer shell 116. The drawer 12 is movably arranged inside the accommodation cavity 113. The inner shell 117 is arranged inside the accommodation cavity 113 and is located below the drawer 12, which improves the structural compactness of the nozzle body assembly 1. The inner shell 117 defines a water outlet cavity 1171. The outlet of the third section 133 of the foam generating device 13 extends into the water outlet cavity 1171. A baffle 118 is arranged at the open end of the water outlet cavity 1171. The baffle 118 can block the flow of the foam mixture in the water outlet cavity 1171, reduce the flow rate of the foam mixture, and thereby reduce the possibility of the foam generating and bursting, so as to ensure the washing effect of the mixture flowing out from the final liquid outlet end 112. At least two confluence plates facing each other are arranged on both sides of the water outlet cavity 1171 in the width direction. The water, washing substances, etc. entering the nozzle body assembly 1 are finally converged in the confluence area 143 and then flow out through the liquid outlet end 112, which can make the mixture sprayed by the nozzle body assembly 1 more uniform. The foam generating device 13 is provided with a liquid inlet 134 and an air inlet 135 that are at least partially opposite to each other in the radial direction of the second section 132. The liquid inlet 134 is communicated with the temporary storage cavity 114, and the air inlet 135 is communicated with the external air.
