[0043] The following describes in detail embodiments of the present invention. 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 with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0044] When existing clothing treatment devices wash clothes, washing substances such as laundry detergent are usually directly put into the clothing treatment cavity of the clothing treatment device, 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 washing effect is not good, which will affect the user experience of the clothing treatment device.

[0045] The following refers to Figures 1-12 Describe the nozzle body assembly according to an embodiment of the present invention.

[0046] The nozzle body assembly 1 according to the present invention includes a housing 11, a foam generating device 13, a drawer 12 and a closing member. The foam generating device 13 is arranged in the housing 11; the drawer 12 is movably arranged in the housing 11, and a feeding cavity 121 is arranged on the drawer 12; the closing member is arranged on the drawer 12, and the closing member selectively conducts or cuts off the feeding cavity 121 and the foam generating device 13.

[0047] According to the spray head body assembly 1 of the present utility model, a housing 11 is provided. The housing 11 is the frame structure of the spray head 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 washing substances is arranged inside the drawer 12. When it is necessary to dose the washing substances, 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 washing substances by the user to the spray head body assembly 1.

[0048] A foam generating device 13 is also arranged inside the housing 11. The foam generating device 13 can foam the washing substances and generate foam and then be used to clean the object to be washed, which can improve the washing effect of the spray head body assembly 1. An opening and closing member is arranged on the drawer 12. The opening and closing member can conduct the dosing chamber 121 and the foam generating device 13 at a specific moment. For example, when the drawer 12 is completely received inside the housing 11, that is, after the drawer 12 has completed dosing the washing substances and is pushed back into the housing 11, in the state as Figure 1 shown, at this time, the opening and closing member can control the conduction between the dosing chamber 121 and the foam generating device 13, and the washing substances in the dosing chamber 121 can enter the foam generating device 13 to foam. The mixed liquid mixed with foam is used to clean the object to be washed, which can improve the cleaning effect of the spray head body assembly 1.

[0049] Through the movable design of the drawer 12 of the spray head body assembly 1, the user can directly put washing substances such as detergents into the dosing chamber 121 inside the drawer 12. When the drawer 12 moves to a certain position inside the housing 11, this certain position can be understood as Figure 1 the position of the drawer 12 shown. The opening and closing member acts to connect the dosing chamber 121 and the foam generating device 13, thereby realizing the automatic dosing of the washing substances, simplifying the user's operation steps, and improving the convenience and experience of the user's operation. The washing substances enter the foam generating device 13 to foam and generate a large amount of foam, which improves the utilization rate of the washing substances. The foamed mixed liquid flows out from the liquid outlet end 112 to be used to clean the object to be washed, which improves the cleaning effect of the spray head body assembly 1.

[0050] In some embodiments, the washing substances can be detergents, fabric softeners, fungicides, or other functional preparations for cleaning, etc.

[0051] According to an embodiment of the present utility model, a temporary storage chamber 114 is formed inside the housing 11 and is open towards the drawer 12. An outlet 122 is formed on the side wall of the dosing chamber 121. The opening and closing member is adapted to conduct the outlet 122 and the temporary storage chamber 114 when the drawer 12 is in the first position.

[0052] The temporary storage chamber 114 can be simply understood as a temporary storage area for the washing substance before it flows into the foam generating device 13. An opening can be formed on the bottom wall of the temporary storage chamber 114 and communicated with the foam generating device 13, so that the washing substance shell 11 entering the temporary storage chamber 114 can enter the foam generating device 13 from the bottom of the temporary storage chamber 114, avoiding the residue of the washing substance in the temporary storage chamber 114. The temporary storage chamber 114 is open towards the drawer 12. A liquid outlet 122 facing the open mouth of the temporary storage chamber 114 is formed on the side wall of the feeding chamber 121. The opening and closing member can be arranged at the position of the liquid outlet 122 or at other positions. The opening and closing member is used to open or close the liquid outlet 122.

[0053] When the drawer 12 moves to the first position, such as Figure 1 the position of the drawer 12 shown in the figure, the opening and closing member opens the liquid outlet 122 to communicate the liquid outlet 122 with the temporary storage chamber 114. The washing substance 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 substance to have a buffering process before entering the foam generating device 13, making the flow rate of the washing substance entering the foam generating device 13 more uniform and facilitating the foaming of the washing substance in the foam generating device 13. The setting of the opening and closing member makes the process of the washing substance entering the foam generating device 13 controllable. The washing substance in the feeding chamber 121 can be controlled to enter the foam generating device 13 when needed, and at the same time, the leakage of the washing substance from the liquid outlet 122 in other cases can be avoided.

[0054] According to an embodiment of the present invention, such as Figure 1As shown, a liquid outlet 122 is provided on one side of the dispensing chamber 121 facing the temporary storage chamber 114. The liquid outlet 122 is located on the side wall of the dispensing chamber 121 facing the temporary storage chamber 114, which can prevent excessive leakage of the washing substance during flow due to an overly large gap between the liquid outlet 122 and the open mouth of the dispensing chamber 121. The opening and closing member includes a baffle 123, which is movably arranged at the liquid outlet 122 and can selectively conduct or close the liquid outlet 122. Since the opening and closing member is a key structure connecting the dispensing chamber 121 and the temporary storage chamber 114, the structure of the opening and 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 one side of the dispensing chamber 121 facing the open mouth of the temporary storage chamber 114, and the opening and closing member is constructed as a baffle 123 rotatably arranged at the liquid outlet 122. When the drawer 12 moves 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 does not move 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 moves 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, which can reduce the leakage of the washing substance.

[0055] According to an embodiment of the present invention, as Figure 1 and 7 shown, the nozzle body assembly 1 further includes a door opening post 1141, which is arranged on the side wall of the temporary storage chamber 114 and extends towards 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.

[0056] The door-opening pillar 1141 can be simply understood as a driving device for driving the baffle 123 to rotate. The door-opening pillar 1141 is arranged on the side wall of the temporary storage cavity 114 and extends towards the baffle 123. When the drawer 12 moves to the first position, the baffle 123 contacts the door-opening pillar 1141 and is pushed open by the door-opening pillar 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 pillar 1141, it will rotate by a certain angle under the action of the door-opening pillar 1141 to realize the rotation of the baffle 123 to open the liquid outlet 122. The setting of the door-opening pillar 1141 makes the rotation of the baffle 123 more automated, simplifies the operation process of opening the liquid outlet 122, and is used to realize the inflow of the washing substance in the dosing cavity 121 into the temporary storage cavity 114 without manual operation, improving the automation degree of the nozzle body assembly 1 and the convenience during use.

[0057] According to an embodiment of the present invention, the foam generating device 13 is located below the drawer 12, and a liquid inlet 134 for connecting the foam generating device 13 with the temporary storage cavity 114 is arranged on the foam generating device 13. When the drawer 12 is retracted into the housing 11, at least part of the foam generating device 13 is located below the drawer 12. Such a layout design makes the structure of the nozzle body assembly 1 more compact. The foam generating device 13 is provided with a liquid inlet 134, and the liquid inlet 134 can be communicated with the opening at the bottom of the temporary storage cavity 114. The washing substance entering the temporary storage cavity 114 can enter the foam generating device 13 through the liquid inlet 134. The setting of the liquid inlet 134 realizes the connection relationship between the temporary storage cavity 114 and the foam generating device 13.

[0058] According to an embodiment of the present invention, the housing 11 is provided with a water inlet end 111 and a liquid outlet end 112. 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. The liquid inlet 134 is arranged on the second section 132; wherein, the diameter of the second section 132 is smaller than that of the first section 131.

[0059] 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 which are connected to each other. Among them, the first section 131 communicates 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 communicating 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. Because 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 nozzle body assembly 1.

[0060] According to an embodiment of the present invention, the foam generating device 13 further includes: a third section 133, one end of the third section 133 communicates with the other end of the second section 132, and the other end of the third section 133 communicates with the liquid outlet end 112, and 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 smaller than the flow rate of the mixed liquid in the second section 132. At this time, the foam in the foam mixed liquid can grow and stabilize in more time and space, 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.

[0061] According to an embodiment of the present invention, 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 that 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.

[0062] In addition, the air inlet 135 and the liquid inlet 134 can be at least partially opposite to each other. Since the air inlet 135 and the liquid inlet hole are at least partially opposite to each other in the radial direction of the second section 132, when the washing substance flows through the liquid inlet hole 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 simultaneously, ensuring that the air and the mixed liquid can fully contact and mix in the foam generating device 13, thereby generating more and more stable foam.

[0063] According to an embodiment of the present invention, the housing 11 includes: an outer housing 116, an inner housing 117, and a baffle 118. An accommodation cavity 113 is formed inside the outer housing 116; the inner housing 117 is disposed in the accommodation cavity 113 and defines a water outlet cavity 1171 that opens toward 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.

[0064] As Figure 7 shown, the housing 11 can be simply divided into an outer housing 116 and an inner housing 117. Among them, an accommodation cavity 113 for accommodating the drawer 12 is formed inside the outer housing 116; the inner housing 117 is disposed in the accommodation cavity 113. In Figure 7 it can be understood that the inner housing 117 is disposed on the bottom wall of the accommodation cavity 113. The inner housing 117 defines a water outlet cavity 1171 that opens toward the liquid outlet end 112 and communicates with the liquid outlet end 112 inside the accommodation cavity 113. The outlet of the third section 133 is located in 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 in 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. The water outlet cavity 1171 can buffer the foam mixed liquid and reduce the possibility of foam rupture to ensure the washing effect of the final mixed liquid.

[0065] The laundry treatment device according to the present invention will be briefly described below.

[0066] The laundry treatment device according to the present utility model includes the spray head body assembly 1 in the above embodiment. Since the laundry treatment device according to the present utility model is provided with the spray head body assembly 1 in the above embodiment, after the spray head body assembly 1 is assembled to the laundry treatment device, the spray head body assembly 1 can discharge the mixed liquid mixed with foam into the laundry treatment chamber of the laundry treatment device 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.

[0067] In some embodiments, a workbench can be provided on the laundry treatment device. During assembly, the spray head body assembly 1 can be assembled to the workbench. The setting of the workbench can integrate the spray head body assembly 1 and the operation unit of the laundry treatment device into the same structure, facilitating user operation.

[0068] In some embodiments, a first waterway is formed in the housing 11 to connect the water inlet end 111 and the water outlet end and flow through the foam generating device 13. Among them, the inlet of the foam generating device 13 is connected to the inlet of the first waterway, and the outlet of the foam generating device 13 is connected to the outlet of the first waterway. The water introduced from the water inlet end 111 can enter the foam generating device 13 after being guided by at least part of the first waterway. 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 foam and generate a large amount of foam. The mixed liquid mixed with foam flows out from the outlet of the foam generating device 13, then flows to the liquid outlet end 112 and finally flows out of the spray head body assembly 1 through the liquid outlet end 112 for cleaning the object to be washed. The cooperation between the first waterway and the foam generating device 13 can make the mixed liquid of the washing substance generate foam, thereby improving the washing effect of the spray head body assembly 1.

[0069] In some embodiments, a section of the first waterway from the water inlet end 111 to the inlet of the foam generating device 13 can be understood as the water inlet channel 115. In terms of layout, the water inlet channel 115 and the temporary storage chamber 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 the feeding chamber 121, the temporary storage chamber 114, and the water inlet channel 115. The layout of the water inlet channel 115 improves the compactness of the structure of the spray head body assembly 1. At the same time, the water inlet channel 115 is located on the side of the temporary storage chamber 114 away from the drawer 12, avoiding the influence of the movement of the drawer 12 in the storage wall surface on the water flow in the water inlet channel 115, preventing water flow fluctuations or interruptions, and ensuring the continuity and stability of the water flow entering the foam generating device 13 from the water inlet channel 115, and thus ensuring the continuous generation of foam.

[0070] In some embodiments, a second waterway 16 is further provided on the nozzle body assembly 1. The second waterway 16 also connects 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 into the dispensing chamber 121. A part of the water entering from the water inlet end 111 can directly flow into the dispensing chamber 121 through the second flow path. The water entering the dispensing chamber 121 can overflow from at least part of the side wall of the dispensing 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 dispensing chamber 121 and then 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.

[0071] In addition, the second waterway 16 is provided 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.

[0072] In some embodiments, the second waterway 16 is provided with a plurality of spaced-apart water inlet holes 161 on the upper surface of the housing 11, and each water inlet hole 161 is respectively communicated with the dispensing 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 dispensing chamber 121 from multiple different positions, improving the rate of water entering the dispensing chamber 121. At the same time, when the water in the second waterway 16 enters the dispensing chamber 121 from the plurality of water inlet holes 161, it can impact the washing substance in the dispensing chamber 121 and make the washing substance mix and foam with the water, increasing the foam content of the mixed liquid overflowing from the dispensing chamber 121 and improving the washing effect of the mixed liquid flowing out from the dispensing chamber 121 through the liquid outlet end 112 after flowing through the second waterway 16.

[0073] In some embodiments, the first waterway and the second waterway 16 can flow water simultaneously. For example, on-off valves can be respectively assembled at the connection position between the water inlet end 111 and the first waterway and the connection position between the water inlet end 111 and the second waterway 16. The on-off valves can be used to selectively control the on or off states of the first waterway and the second waterway 16 respectively. The design of the on-off valves can provide different choices for the liquid outlet of the nozzle body assembly 1. For example, the first waterway and the second waterway 16 can be selectively turned on or turned on simultaneously. Different choices result in different washing effects of the nozzle body assembly 1, and the appropriate method can be selected according to the washing requirements, improving the flexibility and controllability of the nozzle body assembly 1.

[0074] In some embodiments, as Figure 5 、 Figure 7 andFigure 11 As shown, the main body of the baffle 118 is configured as a plate body 1181. The plate body 1181 is provided with second engaging portions 1182 at both ends in the width direction shown in Figure 7 . Correspondingly, the inner shell 117 is provided with first engaging portions 1172 on two side walls in the width direction. The first engaging portions 1172 can cooperate with the second engaging 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.

[0075] In some embodiments, the first engaging portion 1172 is configured as a mounting hole, and the second engaging 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.

[0076] In some embodiments, as Figure 12 shown, a guiding inclined surface 11821 can be machined on the second engaging portion 1182. The guiding inclined surface 11821 can guide the cooperation between the first engaging portion 1172 and the second engaging portion 1182, improving the assembly efficiency of the baffle 118.

[0077] In some embodiments, the inner shell 117 is provided with a first limiting portion 1173, and the plate body 1181 is provided with a second limiting portion 1183 adapted to be in limiting cooperation with the first limiting portion 1173. 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 inner shell 117 is provided with the first limiting portion 1173, and the top of the plate body 1181 is provided with the second limiting portion 1183. It can also be understood that the second limiting portions 1183 are provided to protrude towards each other and abut. After the baffle 118 is assembled with the inner shell 117, 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 figure, enabling the baffle 118 to achieve the flow blocking effect.

[0078] In some embodiments, as Figure 5 , Figure 7 and Figure 11 shown, a abutting 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 abutting surface 1174. The setting of the abutting surface 1174 can increase the cooperation 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.

[0079] In some embodiments, such as Figure 7 and Figure 11 shown, one end of the plate body 1181 in the height direction is provided with a second limiting portion 1183, and the other end is provided with a third limiting portion 1184. The third limiting portion 1184 extends in the direction away from the water outlet cavity 1171. When the baffle plate 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 plate 118 shown in Figure 11 in the counterclockwise direction, which is convenient for the baffle plate 118 to block the foam mixture flowing out of the water outlet cavity 1171.

[0080] In some embodiments, such as Figure 9 shown, on both sides of the water outlet cavity 1171 in the width direction, a first confluence plate 141 and a second confluence plate 142 are respectively provided. The first confluence plate 141 and the second confluence plate 142 face each other and define a confluence area 143. The mixture overflowing from the dosing cavity 121, the foam mixture flowing out of the water outlet cavity 1171, or the mixture flowing out from other positions in the housing 11 can all converge in the confluence area 143. By defining the confluence area 143, the convergence of the mixture can be controlled, so that the mixture finally flowing out from the liquid outlet end 112 can more evenly cover the object to be washed or a specific area to be cleaned, and the problem of poor cleaning effect or resource waste caused by uneven distribution of the mixture can be avoided.

[0081] In addition, the first confluence plate 141 and the second confluence plate 142 can also increase the structural strength of the spray head body assembly 1 and reduce the wear caused by the impact of water flow and mixture.

[0082] In some embodiments, a sink 1213 is formed on the bottom wall of the dosing cavity 121, and a siphon device 15 can be arranged in the sink 1213, as shown in 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 cavity 121 and the water introduced into the dosing cavity 121 through the second waterway 16 by siphon for washing clothes, avoiding the residue of washing substances and water in the dosing cavity 121, and effectively avoiding the problem of secondary pollution of the dosing cavity 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 cavity 121.

[0083] In some embodiments, such as Figure 10As shown in the figure, the siphon device 15 includes a siphon tube 151 and a siphon cylinder 152. The siphon tube 151 is arranged on the bottom wall of the sink 1213, and a first siphon water path 1511 that connects the feeding cavity 121 and the confluence area 143 is formed inside the siphon tube 151; the siphon cylinder 152 covers at least 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 that connects the feeding cavity 121 and the second siphon water path 1521 is left between the siphon cylinder 152 and the bottom wall of the sink 1213.

[0084] Specifically, the siphon tube 151 is arranged on the bottom wall of the sink 1213, and the siphon cylinder 152 is sleeved on the outer periphery of the siphon tube 151 to facilitate the formation of the siphon gap 153 at the bottom wall position of the sink 1213. The residual water and washing substances in the feeding cavity 121 can flow into the confluence area 143 through the siphon gap 153, the second siphon water path 1521, and the first siphon water path 1511 in sequence. The installation position and internal structure of the siphon device 15 ensure that the siphon device 15 can remove the residues at the bottom of the feeding cavity 121, improving the siphon effect.

[0085] In some embodiments, water outlets 1214 are formed on at least part of the side walls of the feeding cavity 121. It can also be simply understood that at least one side wall of the feeding cavity 121 is lower than the adjacent side walls to form the water outlets 1214. After the water in the first water path enters the feeding cavity 121 and mixes with the washing substances, it can directly overflow to the confluence area 143 through the water outlets 1214.

[0086] In some embodiments, the feeding cavity 121 includes a first cavity 1211 and a second cavity 1212. The first cavity 1211 and the second cavity 1212 respectively connect the water inlet end 111 and the liquid outlet end 112. The first cavity 1211 and the second cavity 1212 can be used to accommodate different washing substances, such as detergents and disinfectants.

[0087] In some embodiments, the feeding assembly further sets a marking plate 17 extending towards the inside of the feeding cavity 121 on the siphon cylinder 152. Scale markings 171 are set on the marking plate 17. The position of the scale markings 171 is not higher than the lowest side wall of the feeding cavity 121, or the scale markings 171 are not higher than the standardized maximum height for feeding washing substances in the feeding cavity 121. When the user feeds the washing substances, the scale markings 171 can be used to intuitively judge whether the amount of the fed washing substances is appropriate, avoiding the situation that too much washing substances flow out from the side walls of the feeding cavity 121 and affecting the washing effect. The setting of the scale markings 171 can improve the user experience.

[0088] 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 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 plate 118 is arranged at the open end of the water outlet cavity 1171. The baffle plate 118 can block the flow of the foam mixture in the water outlet cavity 1171, reduce the flow rate of the foam mixture, and further reduce the possibility of foam generation and rupture, 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 and washing substances 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. At the same time, the temporary storage cavity 114 can be communicated with the dosing cavity 121 when the drawer 12 is in the first position through the cooperation between the baffle 123 at the liquid outlet 122 of the dosing cavity 121 and the door opening post 1141, so that the washing substances in the dosing cavity 121 can enter the foam generating device 13 through the temporary storage cavity 114 for foaming, thereby improving the washing effect of the nozzle body assembly 1. The water inlet end 111 in the dosing cavity 121 is communicated through the second waterway 16, and the foam generating device 13 is communicated with the water inlet end 111 through the water inlet channel 115 in the first waterway. During assembly, at least part of the water inlet channel 115 and at least part of the second waterway 16 are arranged at intervals on the outer surface of the outer shell 116, further improving the structural compactness of the nozzle body assembly 1. Through the first waterway and the second waterway 16, at least two flow routes of the washing substances are realized, such as the direct outflow of the mixture of the washing substances and water in the dosing cavity 121, or the outflow of the washing substances in the dosing cavity 121 after foaming in the foaming device. The nozzle body assembly 1 can select at least one of the above ways to discharge the mixture of the washing substances to the laundry treatment device according to actual needs, improving the flexibility of the nozzle body assembly 1.
