[0046] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein 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 utility model and should not be construed as a limitation to the present utility model.

[0047] When existing laundry treatment equipment washes clothes, washing substances such as laundry detergent are usually directly placed into the laundry treatment cavity of the laundry treatment equipment, or the washing substances are placed into the placing assembly and then washed away by tap water. In this way, the washing substances cannot be fully dissolved and foamed, the dissolution effect of the detergent is not good, and it will affect the washing degree of the laundry treatment equipment and the user experience.

[0048] The following refers to Figures 1 - 13 Describe the nozzle body assembly according to the embodiments of the present utility model.

[0049] 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. A temporary storage cavity 114 is formed inside the housing 11; the drawer 12 is movably arranged in the housing 11 and can optionally be moved to be located inside the housing 11. A placement cavity 121 is formed inside the drawer 12; the foam generating device 13 is arranged in the housing 11 and is communicated with the temporary storage cavity 114; wherein, the drawer 12 is provided with a communicating waterway, and when the drawer 12 is received in the housing 11, the communicating waterway communicates the placement cavity 121 with the temporary storage cavity 114.

[0050] 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 temporary storage cavity 114 is formed inside the housing 11. The temporary storage cavity 114 can be understood as a space for temporarily storing washing substances. The drawer 12 can be 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 placement cavity 121 for accommodating washing substances is arranged inside the drawer 12. When the user needs to place the washing substances, the drawer 12 can be pulled out of the housing 11 and the washing substances can be put into the placement cavity 121; after the placement 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 the user placing washing substances into the nozzle body assembly 1.

[0051] A foam generating device 13 communicated with the temporary storage cavity 114 is also arranged inside the housing 11. The foam generating device 13 can foam the washing substances 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. The drawer 12 can realize the conduction relationship between the placement cavity 121 and the foam generating device 13 by changing its relative position with respect to the housing 11. Specifically, when the drawer 12 moves into the housing 11, the communicating waterway communicates the placement cavity 121 with the temporary storage cavity 114, and further communicates the placement cavity 121 with the foam generating device 13; when the drawer 12 is in other positions, the placement cavity 121 and the temporary storage cavity 114 are in a non-conducted state, and at this time, the placement cavity 121 and the foam generating device 13 are in a non-conducted state.

[0052] When the drawer 12 is located inside the housing 11, such as Figure 1 the position of the drawer 12 shown at this time can be understood as being located inside the housing 11. At this time, that is, the placement cavity 121 and the temporary storage cavity 114 are conducted, and the washing substances in the placement cavity 121 can enter the temporary storage cavity 114 through the liquid inlet 134 and then flow into the foam generating device 13 for foaming. The setting of the foam generating device 13 enables the washing substances sucked out from the placement cavity 121 to be mixed with air and water to generate foam. Compared with directly spraying the washing substances onto the surface of the object to be washed, the foamed washing substances can better cover the surface of the clothes, improve the washing effect, and at the same time reduce the waste of washing substances.

[0053] Through the movable design of the extraction drawer 12 of the nozzle body assembly 1, users can directly place washing substances such as detergents into the dosing chamber 121 inside the extraction drawer 12. When the extraction drawer 12 moves into the housing 11, the dosing chamber 121 communicates with the temporary storage chamber 114, and further the dosing chamber 121 communicates with the foam generating device 13, thus realizing the automatic dosing of the washing substances, simplifying the user's operation steps, and improving the convenience of use. The washing substances enter the foam generating device 13 to generate a large amount of foam, improving the dissolution effect and utilization rate of the washing substances. The mixed liquid mixed with foam flows out from the liquid outlet end 112 for cleaning the object to be washed, improving the cleaning effect and user experience of the laundry treatment equipment.

[0054] According to an embodiment of the present invention, a receiving chamber 113 extending in the front-rear direction is formed inside the housing 11. The extraction drawer 12 is movably arranged inside the receiving chamber 113, and the temporary storage chamber 114 is arranged at the rear side of the receiving chamber 113.

[0055] The receiving chamber 113 can extend in the front-rear direction of the housing 11. Here, the front-rear direction can also be understood as the moving direction of the extraction drawer 12, and the temporary storage chamber 114 is arranged at the rear side of the receiving chamber 113. Such a layout design can improve the structural compactness of the nozzle body assembly 1, and at the same time can make the conduction state more stable when the dosing chamber 121 and the temporary storage chamber 114 are conducted.

[0056] According to an embodiment of the present invention, the foam generating device 13 is arranged inside the housing 11 and is located below the temporary storage chamber 114. The foam generating device 13 is provided with a liquid inlet 134 communicating with the temporary storage chamber 114.

[0057] When the extraction drawer 12 is received inside the housing 11, at least part of the foam generating device 13 is located below the extraction 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 communicate with the opening at the bottom of the temporary storage chamber 114. The washing substances entering the temporary storage chamber 114 can enter the foam generating device 13 through the liquid inlet 134. The setting of the liquid inlet 134 realizes the communication relationship between the temporary storage chamber 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 communicates with the water inlet end 111; one end of the second section 132 communicates with the other end of the first section 131, and the other end of the second section 132 communicates with the liquid outlet end 112. The second section 132 is provided with a liquid inlet 134; wherein, the diameter of the second section 132 is smaller than the diameter of the first section 131.

[0059] Since the foam generating device 13 is a structure for guiding the washing substance to foam, 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 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 into the housing 11, 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 coverage 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 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, 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, more persistent and stable foam can be formed, the foam quality is improved, and the possibility of the foam breaking during the flow is reduced, thereby ensuring the washing effect of the nozzle body assembly 1.

[0061] An air inlet 135 communicating with the outside is formed on the foam generating device 13 according to the present invention, and the air inlet 135 and the liquid inlet 134 are at least partially opposite to each other in the radial direction of the foam generating device 13.

[0062] 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, thereby forming a low-pressure area in the second section 132. At this time, by providing an 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, and then rich foam is generated, 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 the foaming quality of the foam generating device 13.

[0063] According to an embodiment of the present invention, the diameter of the second section 132 is d1, and the diameter of the liquid inlet 134 is d2, and it satisfies: 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 it satisfies: 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, resulting in insufficient washing substance in the main flow path, reducing the generated foam, and further leading to a decrease 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, resulting in excessive 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, thereby reducing the washing effect. Therefore, the ratio of the diameter of the liquid inlet 134 to the diameter of the second section 132 should be in 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.

[0064] According to an embodiment of the present utility model, 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 will affect 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. 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, which will cause insufficient gas mixed with the liquid mixture in the foam generating device 13, resulting in a decrease in 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 air inlet 135 with too large a size is likely to cause the liquid mixture to leak from the air inlet 135. Thus, the ratio of the diameter of the air inlet 135 to the diameter of the second section 132 should be within a relatively appropriate 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.

[0065] According to an embodiment of the present utility model, if the diameter of the second section 132 is d1 and the diameters of the first section 131 and the third section 133 are both d4, then 0.35 ≤ d1 / d4 ≤ 0.45 is satisfied. Since the second section 132 is provided 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 liquid mixture 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 decrease 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, and the washing substances and water are fully mixed. Due to the small change in the flow rate in the flow path, the liquid mixture will be relatively stable, resulting in a decrease in the generated foam. Thus, 0.35 ≤ d1 / d4 ≤ 0.45 is a relatively appropriate 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.

[0066] According to an embodiment of the present utility model, a liquid outlet 122 is provided in the feeding cavity 121. A baffle 123 is rotatably provided at the liquid outlet 122. A door-opening post 1141 extending towards the baffle 123 is provided in the temporary storage cavity 114. 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 moved into the housing 11.

[0067] Specifically, as Figure 1 shown, a liquid outlet 122 is formed on the side wall of the feeding cavity 121 facing the temporary storage cavity 114. The liquid outlet 122 is directly opposite to the open mouth of the temporary storage cavity 114, facilitating the communication between the liquid outlet 122 and the temporary storage cavity 114. A baffle 123 is provided at the position of the liquid outlet 122. The baffle 123 can rotate at the position of the liquid outlet 122 to close or open the liquid outlet 122. The setting of the baffle 123 enables the communication relationship between the liquid outlet 122 and the temporary storage cavity 114 to be controllable. When the drawer 12 is received in the housing 11, the baffle 123 can rotate and open the liquid outlet 122 to connect the feeding cavity 121 and the temporary storage cavity 114; when the drawer 12 is in other positions, the baffle 123 closes the liquid outlet 122. The setting of the baffle 123 also prevents the leakage of the washing substance in the feeding cavity 121. A door-opening post 1141 is provided on the side wall of the temporary storage cavity 114. The door-opening post 1141 extends towards the liquid outlet 122. When the drawer 12 is moved into the housing 11, the door-opening post 1141 can push the baffle 123 to rotate. The door-opening post 1141 can be understood as a driving device for driving the baffle 123 to rotate. The setting of the door-opening post 1141 makes the rotation of the baffle 123 automatic, that is, the communication between the feeding cavity 121 and the temporary storage cavity 114 is automatic, without manual operation by the user, improving the user experience.

Since the clothes treatment device according to the present utility model is provided with the nozzle body assembly 1 in the above embodiment, after the nozzle body assembly 1 is assembled to the clothes treatment device, the nozzle body assembly 1 can inject a mixed liquid mixed with foam into the clothes treatment cavity of the clothes treatment device for cleaning clothes, improving the utilization rate of the washing substance, and further improving the washing effect and user experience of the clothes treatment device.

[0070] In some embodiments, a first waterway is formed in the housing 11 to communicate the water inlet end 111 with the water outlet end and flow through the foam generating device 13. Among them, the inlet of the foam generating device 13 is communicated with the inlet of the first waterway, and the outlet of the foam generating device 13 is communicated with 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 and foamed with the washing substance entering the foam generating device 13 through the liquid inlet 134 to generate a large amount of foam. The mixed liquid mixed with the foam flows out through the outlet of the foam generating device 13 and then flows to 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 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 nozzle body assembly 1.

[0071] In some embodiments, a section of the first waterway between the water inlet end 111 and 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 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 the feeding cavity 121, the temporary storage cavity 114, and the water inlet channel 115. The layout of the water inlet channel 115 improves the structural compactness 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.

[0072] In some embodiments, the nozzle body assembly 1 further includes: a second waterway 16. The second waterway 16 is arranged on the upper surface of the housing 11 and is arranged at intervals from at least part of the water inlet channel 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 feeding cavity 121. Specifically, a second waterway 16 is also provided on the nozzle body assembly 1. 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 feeding cavity 121. A part of the water flow entering from the water inlet end 111 can directly flow into the feeding cavity 121 through the second flow path. The water entering the feeding cavity 121 can overflow from at least part of the side wall of the feeding cavity 121 and flow to 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 feeding cavity 121 for cleaning 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.

[0073] 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 the arrangement of the nozzle body assembly 1 is facilitated.

[0074] 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 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 a plurality of 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 substances in the dosing chamber 121 and mix the washing substances with water to form 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 then flowing out through the liquid outlet end 112.

[0075] In some embodiments, the first waterway and the second waterway 16 can conduct water flow simultaneously. For example, on-off valves can be respectively assembled at the connection positions of the water inlet end 111 and the first waterway and at the connection positions of the water inlet end 111 and the second waterway 16, and 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, it can be selected to conduct the first waterway and the second waterway 16 respectively or simultaneously. Different choices result in different washing effects of the nozzle body assembly 1, and appropriate methods can be selected according to the washing requirements, improving the flexibility and controllability of the nozzle body assembly 1.

[0076] In some embodiments, 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 arranged inside the accommodation cavity 113. In Figure 7 it can be understood that the inner housing 117 is arranged on the bottom wall of the accommodation cavity 113. The inner housing 117 defines a water outlet cavity 1171 in the accommodation cavity 113 that is open towards the liquid outlet end 112 and communicated 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, as Figure 8As shown, a baffle 118 is provided at the open mouth of the water outlet chamber 1171. The baffle 118 closes at least part of the open mouth of the water outlet chamber 1171. Therefore, the foam liquid mixture in the water outlet chamber 1171 needs to overflow from the upper part of the baffle 118. The water outlet chamber 1171 can be simply understood as a space area for temporarily storing the liquid mixture. The foam liquid mixture flowing out from the third section 133 has a high speed. The water outlet chamber 1171 can buffer the foam liquid mixture, reducing the possibility of the foam breaking and ensuring the washing effect of the final liquid mixture.

[0077] In some embodiments, as Figure 5 , Figure 7 and Figure 11 shown, the main body part of the baffle 118 is constructed as a plate body 1181. Second engaging portions 1182 are provided at both ends of the plate body 1181 in the width direction shown in Figure 7 . Correspondingly, first engaging portions 1172 are provided on two side walls of the inner shell 117 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.

[0078] In some embodiments, the first engaging portion 1172 is constructed as a mounting hole, and the second engaging portion 1182 is constructed 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 assembly stability of the baffle 118.

[0079] 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.

[0080] In some embodiments, 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 liquid mixture in the water outlet chamber 1171 and change the flow direction of the foam liquid 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.

[0081] In some embodiments, as Figure 7 and Figure 11 shown, an 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 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.

[0082] In some embodiments, as Figure 7 and Figure 11 shown, a second limiting portion 1183 is provided at one end of the plate body 1181 in the height direction, and a third limiting portion 1184 is provided at the other end. The third limiting portion 1184 extends in a direction away from the water outlet cavity 1171. After 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 shown in Figure 11 in the counterclockwise direction, facilitating the baffle 118 to block the foam mixture flowing out of the water outlet cavity 1171.

[0083] In some embodiments, as Figure 9 shown, a first confluence plate 141 and a second confluence plate 142 are respectively provided 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 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 poor cleaning effect or waste of resources caused by uneven distribution of the mixture can be avoided.

[0084] 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 mixture.

[0085] 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 Figure 8 and Figure 10As 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 from the second waterway 16 by siphoning, and is used 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.

[0086] In some embodiments, such as Figure 8 and Figure 10 As shown, the siphon device 15 includes a siphon pipe 151 and a siphon cylinder 152. The siphon pipe 151 is arranged on the bottom wall of the sink 1213, and a first siphon waterway 1511 communicating the dosing cavity 121 with the confluence area 143 is formed in the siphon pipe 151; the siphon cylinder 152 covers at least part of the outer periphery of the siphon pipe 151, and a second siphon waterway 1521 is formed between the siphon cylinder 152 and the siphon pipe 151; wherein, a siphon gap 153 communicating the dosing cavity 121 with the second siphon waterway 1521 is left between the siphon cylinder 152 and the bottom wall of the sink 1213.

[0087] Specifically, the siphon pipe 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 pipe 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 dosing cavity 121 can pass through the siphon gap 153, then pass through the second siphon waterway 1521 and the first siphon waterway 1511 in sequence and then flow into the confluence area 143. 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 dosing cavity 121, improving the siphon effect.

[0088] In some embodiments, water outlets 1214 are formed on at least part of the side walls of the dosing cavity 121. It can also be simply understood that at least one side wall of the dosing cavity 121 is lower than the adjacent side walls to form the water outlets 1214. After the water in the first waterway enters the dosing cavity 121 and is mixed with the washing substances, it can directly overflow to the confluence area 143 through the water outlets 1214.

[0089] In some embodiments, the dosing cavity 121 includes a first cavity 1211 and a second cavity 1212. The first cavity 1211 and the second cavity 1212 respectively communicate the water inlet end 111 and the liquid outlet end 112, and the first cavity 1211 and the second cavity 1212 can be used to accommodate different washing substances, such as detergents and disinfectants, etc.

[0090] In some embodiments, the dispensing assembly further provides a marking plate 17 extending towards the inside of the dispensing cavity 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 dispensing cavity 121, or the scale marking 171 is not higher than the standardized maximum height for dispensing the washing substance in the dispensing cavity 121. When the user dispenses the washing substance, the amount of the dispensed washing substance can be visually judged through the scale marking 171, so as to avoid the washing substance flowing out directly from positions such as the side wall of the dispensing cavity 121 and affecting the washing effect. The setting of the scale marking 171 can improve the user experience.

[0091] 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, improving 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 converging 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 convergence area 143 and flow out through the liquid outlet end 112, making 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 inside the housing 11 through the cooperation between the baffle 123 at the liquid outlet 122 of the dosing cavity 121 and the door opening column 1141, enabling the washing substances in the dosing cavity 121 to 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 after the washing substances in the dosing cavity 121 are mixed with water, or the outflow after the washing substances in the dosing cavity 121 enter the foaming device for foaming. The nozzle body assembly 1 can select at least one of the 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.
