[0046] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with 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 a limitation of the present invention.

[0047] When existing laundry treatment equipment washes clothes, laundry detergents and other washing substances are usually directly put into the laundry treatment cavity of the laundry treatment equipment, or the washing substances are put into the dosing assembly and then washed away by tap water. In related technologies, some laundry treatment equipment is provided with a foaming device. However, the outlet of the foaming structure is usually directly communicated with the laundry treatment cavity, which easily causes the foam mixture flowing out of the foaming structure to be uneven, thereby affecting the washing effect.

[0048] The following refers to Figures 1 - 12 Describe the nozzle body assembly according to the embodiments of the present invention.

[0049] The nozzle body assembly 1 according to the present utility model includes: a housing 11, a foam generating device 13, and a baffle 118. The housing 11 is provided with a water inlet end 111 and a liquid outlet end 112; the foam generating device 13 is disposed in the housing 11 and is respectively communicated with the water inlet end 111 and the liquid outlet end 112; the baffle 118 is disposed in the housing 11 and is located between the outlet of the foam generating device 13 and the liquid outlet end 112 and is used to block the mixed liquid flowing out of the foam generating device 13.

[0050] The nozzle body assembly 1 according to the present utility model is provided with a housing 11. A foam generating device 13 that communicates the water inlet end 111 and the liquid outlet end 112 is disposed in the housing 11. After the washing substance enters the foam generating device 13, it can be mixed with water and air in the foam generating device 13 to generate foam. Compared with directly spraying the washing substance onto the surface of the object to be washed, the foamed washing substance can better cover the surface of the clothes, improve the washing effect, and reduce the waste of the washing substance at the same time. The setting of the foam generating device 13 improves the washing effect of the nozzle body assembly 1.

[0051] A baffle 118 is further disposed between the outlet of the foam generating device 13 and the liquid outlet end 112. The baffle 118 can block the mixed liquid flowing out of the foam generating device 13, reduce the flow rate of the mixed liquid, and thereby reduce the possibility of the foam breaking, so as to ensure the washing effect of the final mixed liquid.

[0052] In some embodiments, the washing substance may be a detergent, a fabric softener, a bactericide, or other functional preparations for cleaning, etc.

[0053] According to an embodiment of the present utility model, the housing 11 includes: an outer shell 116 and an inner shell 117. An accommodation cavity 113 is formed in the outer shell 116; the inner shell 117 is disposed in the accommodation cavity 113 and defines a water outlet cavity 1171 that opens towards the liquid outlet end 112. The outlet of the foam generating device 13 extends into the water outlet cavity 1171 and is communicated with the water outlet cavity 1171. The baffle 118 is disposed at the open mouth of the water outlet cavity 1171.

[0054] According to an embodiment of the present utility model, the housing 11 includes: an outer shell 116 and an inner shell 117. An accommodation cavity 113 is formed in the outer shell 116; the inner shell 117 is disposed in the accommodation cavity 113 and defines a water outlet cavity 1171 that opens towards the liquid outlet end 112. The outlet of the foam generating device 13 extends into the water outlet cavity 1171 and is communicated with the water outlet cavity 1171. The baffle 118 is disposed at the open mouth of the water outlet cavity 1171.

[0055] Such as Figure 5 and Figure 7As shown, the housing 11 can be simply divided into an outer housing 116 and an inner housing 117. Among them, a receiving cavity 113 is formed inside the outer housing 116, and the receiving cavity 113 can accommodate structures inside the nozzle body assembly 1 such as the foam generating device 13; the inner housing 117 is disposed inside the receiving cavity 113. In Figure 7 it can be understood that the inner housing 117 is disposed on the bottom wall of the receiving cavity 113. The inner housing 117 defines a water outlet cavity 1171 inside the receiving cavity 113 that opens towards the liquid outlet end 112 and communicates with the liquid outlet end 112. The outlet of the foam generating device 13 is located inside the water outlet cavity 1171. Therefore, the mixed liquid flowing out of the foam generating device 13 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 foam mixed liquid flowing out of the foam generating device 13 has a high speed, and the water outlet cavity 1171 can buffer the foam mixed liquid and reduce the possibility of foam rupture.

[0056] According to an embodiment of the present invention, first fitting portions 1172 are provided on both sides of the inner housing 117 in the width direction. The baffle 118 includes a plate body 1181 and second fitting portions 1182. The plate body 1181 extends in the width direction of the inner housing 117 to close at least part of the open end of the water outlet cavity 1171; the second fitting portions 1182 are disposed at both ends of the plate body 1181 in the extending direction and are adapted to cooperate with the first fitting portions 1172.

[0057] As Figure 11 shown, the main body portion of the baffle 118 is configured as the plate body 1181. Second fitting portions 1182 are provided at both ends of the plate body 1181 in the Figure 7 shown width direction. Correspondingly, as Figure 7 shown, first fitting portions 1172 are provided on two side walls of the inner housing 117 in the width direction. The first fitting portions 1172 can cooperate with the second fitting 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 end of the inner housing 117.

[0058] According to an embodiment of the present invention, the first fitting portion 1172 is configured as a mounting hole, and the second fitting 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.

[0059] According to an embodiment of the present invention, as Figure 12As shown, a guiding inclined surface 11821 is provided on the installation protrusion. 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.

[0060] According to an embodiment of the present utility model, 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 cavity 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 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 Figure 11 the clockwise direction as shown in the baffle 118, enabling the baffle 118 to achieve the flow blocking effect.

[0061] According to an embodiment of the present utility model, the first limiting portion 1173 is provided on the inner shell 117 and extends towards the baffle 118, and a stopping surface 1174 is formed at one end of the first limiting portion 1173 facing the baffle 118; the second limiting portion 1183 is provided at one end of the plate body 1181 in the height direction of the nozzle body assembly 1 and extends towards the first limiting portion 1173, and the second limiting portion 1183 is adapted to abut against the stopping surface 1174.

[0062] As Figure 7 and Figure 11 shown, a stopping 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 stopping surface 1174. The setting of the stopping 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.

[0063] According to an embodiment of the present utility model, a third limiting portion 1184 is provided 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 towards the liquid outlet end 112 to limit the rotation of the baffle 118. As Figure 7 and Figure 11As 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 a 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 in the counterclockwise direction as shown in Figure 11 so as to facilitate the baffle plate 118 to block the foam mixture in the water outlet cavity 1171.

[0064] According to an embodiment of the present invention, first converging plates 141 and second converging plates 142 extending towards each other are respectively arranged 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.

[0065] As Figure 9 shown, first converging plates 141 and second converging plates 142 are respectively arranged on both sides of the water outlet cavity 1171 in the width direction. The first converging plate 141 and the second converging plate 142 face each other and define a converging area 143. The mixed liquid overflowing from the feeding cavity 121, the foam mixture flowing out of the water outlet cavity 1171, or the mixed liquid flowing out from other positions in the housing 11 can all converge in the converging area 143. By defining the converging area 143, the convergence of the mixed liquid can be controlled, so that the mixed liquid finally flowing out from 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 resource waste caused by uneven distribution of the mixed liquid can be avoided.

[0066] In addition, the first converging plate 141 and the second converging 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 mixed liquid.

[0067] The laundry treatment device according to the present invention will be briefly described below.

[0068] The laundry treatment device according to the present invention includes the spray head body assembly 1 in the above embodiment. Since the laundry treatment device according to the present invention is provided with the spray head body assembly 1 in the above embodiment, after the spray head is assembled with the laundry treatment device, the baffle plate 118 can buffer the foam mixture flowing out of the foam generating device 13, ensure the uniformity of the mixed liquid finally entering the laundry treatment device, and reduce the proportion of foam rupture, thereby ensuring the cleaning effect of the laundry treatment device.

[0069] In some embodiments, a workbench may be provided on the laundry treatment device. During assembly, the nozzle body assembly 1 can be assembled onto the workbench. The provision of the workbench can integrate the nozzle body assembly 1 and the operation unit of the laundry treatment device into the same structure, facilitating user operation.

[0070] In some embodiments, a drawer 12 is movably provided in the accommodation cavity 113, 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 by pushing. A placement cavity 121 for accommodating washing substances is provided inside the drawer 12. When it is necessary to place the washing substances, the drawer 12 can be pulled out of the housing 11 to complete the placement; 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.

[0071] In some embodiments, the accommodation cavity 113 can extend in the front-back direction, where the front-back direction can also be understood as the direction in which the drawer 12 moves, and the temporary storage cavity 114 is provided 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, the conduction state when the placement cavity 121 and the temporary storage cavity 114 are in communication can be made more stable.

[0072] In some embodiments, a liquid suction port is formed on the foam generating device 13. The drawer 12 can achieve 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 in the housing 11, it has a first position. When the drawer 12 moves to the first position, the placement cavity 121 is in communication with the foam generating device 13 through the liquid inlet 134; when the drawer 12 is in other positions, the placement cavity 121 and the liquid inlet 134 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.

[0073] 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, or it can be understood as the position when the drawer is received in the housing 11. At this time, the placement cavity 121 is in communication with the foam generating device 13, and the washing substances in the placement cavity 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 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.

[0074] In some embodiments, such as Figure 1 and 7As shown, a temporary storage cavity 114 is formed inside the housing 11 and is open towards the drawer 12. The temporary storage cavity 114 communicates with the liquid inlet 134 and is selectively communicable with the dosing cavity 121. The temporary storage cavity 114 can be simply understood as a temporary storage area for the washing substance before it flows into the foam generating device 13. Openings can be made on the bottom wall of the temporary storage cavity 114 and communicate with the liquid inlet 134, so that the washing substance entering the temporary storage cavity 114 can enter the foam generating device 13 from the bottom of the temporary storage cavity 114 of the housing 11, avoiding the residue of the washing substance in the temporary storage cavity 114. The temporary storage cavity 114 is open towards the drawer 12. When the drawer 12 is moved to the first position, the washing substance can directly enter the temporary storage cavity 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 cavity 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.

[0075] In some embodiments, the nozzle body assembly 1 further includes: a switching member disposed on the drawer 12 and adapted to communicate the dosing cavity 121 with the temporary storage cavity 114 when the drawer 12 is in the first position. The setting of the switching member makes the communication between the dosing cavity 121 and the temporary storage cavity 114 controllable. When the drawer 12 is in the first position, the switching member can communicate the dosing cavity 121 with the temporary storage cavity 114, and the washing substance in the dosing cavity 121 can enter the temporary storage cavity 114. The flow of the washing substance in the dosing cavity 121 can be controlled through the switching member. Specifically, when the drawer 12 is in other positions, the switching member can be in a closed state, effectively avoiding the leakage of the washing substance from the dosing cavity 121; when the drawer 12 is in the first position, the switching member opens and controls the communication between the dosing cavity 121 and the temporary storage cavity 114, and the washing substance can flow through the temporary storage cavity 114 and then enter the foam generating device 13. The setting of the switching member enables the nozzle body assembly 1 to control the flow of the washing substance in the dosing cavity 121, that is, only when the drawer 12 is in the first position, the washing substance in the dosing cavity 121 can enter the foam generating device 13 through the temporary storage cavity 114, and when the drawer 12 is in other positions, the switching member is in a closed state, which can avoid the leakage problem of the washing substance.

[0076] In some embodiments, such as Figure 1As shown in the figure, a liquid outlet 122 is provided on one side of the dosing chamber 121 facing the temporary storage chamber 114. 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 dosing 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 dosing chamber 121 towards the temporary storage chamber 114. Specifically, a liquid outlet 122 is provided on one side of the dosing 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 dosing 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 dosing 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 dosing 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 dosing 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 dosing chamber 121 cannot flow out, which can reduce the leakage of the washing substance.

[0077] In some embodiments, 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. The door opening post 1141 can be simply understood as a driving device for driving the rotation of the baffle 123. The door opening post 1141 is arranged on the side wall of the temporary storage chamber 114 and extends towards 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 at 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 at 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 automatic, simplifies the operation process of opening the liquid outlet 122, and is used to realize the inflow of the washing substance in the dosing chamber 121 into the temporary storage chamber 114 without manual operation, improving the automation degree of the nozzle body assembly 1 and the convenience during use.

[0078] In some embodiments, a first waterway is formed within the housing 11 to connect 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 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 at the water inlet end 111 can enter the foam generating device 13 after being guided by at least a 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 generate a large amount of foam. The mixed liquid mixed with foam flows out through the outlet of the foam generating device 13 and then flows towards 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 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 clothing treatment device.

[0079] In some embodiments, 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 connected to the water inlet end 111; the second section 132 connects the first section 131 with the liquid outlet end 112, and a liquid inlet 134 communicating with the temporary storage cavity 114 is provided on the second section 132. When the drawer 12 moves to the first position, the washing substance in the feeding cavity 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 from the first section 131 and generate foam. During this process, since the diameter of the first section 131 is larger than that of the second section 132, therefore, the flow rate of the mixed liquid in the second section 132 will increase and generate foam. Since the foam has better covering and penetrating properties, compared with directly putting the washing substance onto 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 clothing treatment device.

[0080] In some embodiments, the foam generating device 13 further includes a third section 133. One end of the third section 133 is connected to the other end of the second section 132, and the other end of the third section 133 is connected to 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, therefore, 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 durable 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.

[0081] In some embodiments, 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 to each other 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.

[0082] In some embodiments, 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 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 stable foam.

[0083] In some embodiments, a section between the water inlet end 111 of the first water path 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 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 fluctuation or interruption, 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.

[0084] In some embodiments, the nozzle body assembly 1 further includes: a second waterway 16 disposed on the upper surface of the housing 11 and spaced apart from at least a portion 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 dispensing chamber 121. Specifically, a second waterway 16 is also provided 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 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 a portion 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 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.

[0085] In addition, the second waterway 16 is disposed on the surface of the housing 11 and spaced apart from at least a portion 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.

[0086] 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 cause the washing substance to 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 from the second waterway 16 to the dispensing chamber 121 and flowing out through the liquid outlet end 112.

[0087] 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 between the water inlet end 111 and the first waterway and 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 options for the liquid discharge 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 selections 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.

[0088] In some embodiments, a sunken groove 1213 is formed on the bottom wall of the dosing chamber 121, and a siphon device 15 can be arranged in the sunken groove 1213, such as Figure 8 and Figure 10 shown. The outlet of the siphon device 15 is communicated with the water outlet channel. 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 means of siphonage and is used for washing clothes, avoiding the residue of 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 sunken groove 1213 is to improve the ability of the siphon device 15 to siphon the residual washing substances and water in the dosing chamber 121.

[0089] 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 arranged on the bottom wall of the sunken groove 1213, and a first siphon waterway 1511 communicating the dosing chamber 121 with the water outlet channel is formed in 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 waterway 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 waterway 1521 is left between the siphon cylinder 152 and the bottom wall of the sunken groove 1213.

[0090] Specifically, the siphon tube 151 is arranged on the bottom wall of the sunken groove 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 sunken groove 1213. The residual water and washing substances in the dosing chamber 121 can flow into the water outlet channel through the siphon gap 153, the second siphon waterway 1521 and the first siphon waterway 1511 in sequence. The installation position and internal structure of the siphon device 15 ensure that the siphon device 15 can suck the residues at the bottom of the dosing chamber 121, improving the siphon effect.

[0091] In some embodiments, a water outlet 1214 is formed on at least 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 walls to form the water outlet 1214. After the water in the first waterway enters the dosing chamber 121 and mixes with the washing substance, it can directly overflow to the confluence area 143 through the water outlet 1214.

[0092] 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, etc.

[0093] In some embodiments, the dosing assembly further provides a marking plate 17 extending towards the inside of the dosing chamber 121 on the siphon tube 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 the washing substance in the dosing chamber 121. When the user doses the washing substance, the amount of the dosed washing substance can be intuitively judged through the scale marking 171, avoiding the washing substance flowing out from positions such as the side wall of the dosing chamber 121 due to excessive amount, which affects the washing effect. The setting of the scale marking 171 can improve the user experience.

[0094] 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 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 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 of 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. 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, and further improve 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 directly flowing out after the washing substances in the dosing cavity 121 are mixed with water, or flowing out 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 above methods 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.
