DETAILED DESCRIPTION

[0027] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar components have the same or similar designations and functions throughout, and embodiments described below are exemplary and are intended for explanation of the present application, and are not to be construed as limiting the present application.

[0028] A spray head body assembly according to embodiments of the present application is described below with reference to Figs. 1-13.

[0029] The spray head body assembly 1 according to the present application includes a housing 11 and a foam generating device 13, which is disposed in the housing 11. The foam generating device 13 can foam a washing material and generate foam for cleaning a washing object, which can improve the washing effect of the spray head body assembly 1.

[0030] In the spray head body assembly 1 according to the present application, the foam generating device 13 is disposed, which can improve the dissolving effect of the washing material, and further improve the washing degree and user experience of the laundry treatment apparatus.

[0031] According to some embodiments of the present application, the nozzle body assembly 1 for the clothes treatment device further comprises a hopper 12 and an on-off member, the hopper 12 is movably arranged in the housing 11, and the hopper 12 is provided with a feeding cavity 121; the on-off member is arranged on the hopper 12, and the on-off member selectively connects or disconnects the feeding cavity 121 and the foam generating device 13.

[0032] In some specific embodiments, the nozzle body assembly 1 comprises a housing 11, a foam generating device 13, a hopper 12 and an on-off member, the foam generating device 13 is arranged in the housing 11; the hopper 12 is movably arranged in the housing 11, and the hopper 12 is provided with a feeding cavity 121; the on-off member is arranged on the hopper 12, and the on-off member selectively connects or disconnects the feeding cavity 121 and the foam generating device 13.

[0033] According to the nozzle body assembly 1 of the present application, the housing 11 is arranged as the frame structure of the nozzle body assembly 1, and the hopper 12 is movably arranged in the housing 11, i.e. the hopper 12 is movable relative to the housing 11, so that the hopper 12 can be moved out of the housing 11 by pulling or moved into the housing 11 by pushing. The hopper 12 is internally provided with a feeding cavity 121 for accommodating washing substances, and when it is necessary to feed the washing substances, the hopper 12 can be pulled out of the housing 11 to complete the feeding, and when the feeding is completed, the hopper 12 can be pushed back into the housing 11. The movable manner of the hopper 12 relative to the housing 11 facilitates the user to feed the washing substances into the nozzle body assembly 1.

[0034] The housing 11 is further provided with the foam generating device 13, which can foam the washing substances and generate foam for cleaning the objects to be washed, so as to improve the washing effect of the nozzle body assembly 1. The hopper 12 is provided with an on-off member, which can connect the feeding cavity 121 and the foam generating device 13 at a specific moment, for example, when the hopper 12 is completely accommodated in the housing 11 and the hopper 12 is pushed back into the housing 11 after the feeding of the washing substances is completed, as shown in FIG. 1, at this moment, the on-off member can control the feeding cavity 121 and the foam generating device 13 to be connected, and the washing substances in the feeding cavity 121 can enter the foam generating device 13 to be foamed, and the mixed liquid mixed with the foam is used to clean the objects to be washed, so as to improve the cleaning effect of the nozzle body assembly 1.

[0035] The spray head body assembly 1 is provided with the movable design of the bucket 12, and a user can directly place a washing material such as a detergent into the pouring cavity 121 in the bucket 12. When the bucket 12 is moved to a position in the housing 11, which can be understood as the position of the bucket 12 shown in FIG. 1, the opening and closing member is actuated to communicate the pouring cavity 121 with the foam generating device 13, so as to realize automatic pouring of the washing material, simplify the use steps of the user, and improve the convenience and experience of the user operation. The washing material enters the foam generating device 13 to generate a large amount of foam, improves the use rate of the washing material, and the mixed liquid after foaming flows out from the liquid outlet end 112 to be used for cleaning the to-be-cleaned object, and improves the cleaning effect of the spray head body assembly 1.

[0036] In some embodiments, the washing material can be a detergent, a softener, a bactericide, or other functional agents for cleaning.

[0037] According to some embodiments of the present application, the temporary storage cavity 114 is formed in the housing 11 and is open to the bucket 12, the side wall of the pouring cavity 121 is provided with the liquid outlet 122, and the opening and closing member is adapted to communicate the liquid outlet 122 with the temporary storage cavity 114 when the bucket 12 is located at the first position.

[0038] The temporary storage cavity 114 can be simply understood as a temporary storage area of the washing material before flowing into the foam generating device 13. The bottom wall of the temporary storage cavity 114 can be provided with a hole and communicated with the foam generating device 13, so that the washing material entering the temporary storage cavity 114 flows into the foam generating device 13 from the bottom of the temporary storage cavity 114, and the residual washing material in the temporary storage cavity 114 is avoided. The temporary storage cavity 114 is open to the bucket 12, the side wall of the pouring cavity 121 is provided with the liquid outlet 122 opposite to the opening of the temporary storage cavity 114, and the opening and closing member can be arranged at the position of the liquid outlet 122 or other positions. The opening and closing member is used to open or close the liquid outlet 122.

[0039] When the bucket 12 is moved to the first position, for example, the position of the bucket 12 shown in FIG. 1, the opening and closing member opens the liquid outlet 122 to communicate the liquid outlet 122 with the temporary storage cavity 114, and the washing material can directly enter the temporary storage cavity 114 without passing through other guide pipeline structures, which can reduce unnecessary structures inside the spray head body assembly 1 and improve the compactness of the spray head body assembly 1. The temporary storage cavity 114 is provided to allow the washing material to have a buffering process before entering the foam generating device 13, so that the flow rate of the washing material entering the foam generating device 13 is more uniform, and the washing material is convenient to foam in the foam generating device 13. The opening and closing member is provided to control the process of the washing material entering the foam generating device 13, so that the washing material in the pouring cavity 121 can enter the foam generating device 13 when needed, and the leakage of the washing material from the liquid outlet 122 in other cases is avoided.

[0040] According to some embodiments of the present application, as shown in FIG. 1, the dispensing cavity 121 is provided with a liquid outlet 122 on the side of the dispensing cavity 121 facing the temporary storage cavity 114. The liquid outlet 122 is located on the side wall of the dispensing cavity 121 facing the temporary storage cavity 114, which can avoid excessive gap between the liquid outlet 122 and the opening of the dispensing cavity 121, thereby preventing leakage when the washing material flows. The opening and closing member includes a baffle 123 which is movably arranged on the liquid outlet 122 and can selectively open or close the liquid outlet 122. Since the opening and closing member is a structure connecting the dispensing cavity 121 and the temporary storage cavity 114, the structure of the opening and closing member will affect the flow of the washing material in the dispensing cavity 121 towards the temporary storage cavity 114. In some embodiments, the dispensing cavity 121 is provided with a liquid outlet 122 on the side of the dispensing cavity 121 facing the opening of the temporary storage cavity 114, and the opening and closing member is configured as a baffle 123 rotatably arranged on the liquid outlet 122. When the bucket 12 moves to the first position, the baffle 123 can be rotated to open the liquid outlet 122, and at this time, the washing material in the dispensing cavity 121 can flow into the temporary storage cavity 114 through the liquid outlet 122. When the bucket 12 is not moved to the first position, the baffle 123 will not be rotated, and at this time, the baffle 123 closes the liquid outlet 122, and the washing material in the dispensing cavity 121 cannot flow into the temporary storage cavity 114. By controlling the rotation of the baffle 123, the flow of the washing material in the dispensing cavity 121 can be controlled. For example, when the bucket 12 moves to the first position, the baffle 123 can be rotated, and the washing material in the dispensing cavity 121 can enter the foam generating device 13. When the bucket 12 is in other positions, the baffle 123 will not be rotated, and the washing material in the dispensing cavity 121 cannot flow out, which can reduce the leakage of the washing material.

[0041] According to some embodiments of the present application, as shown in FIG. 1 and 7, the spray head body assembly 1 further includes a door opening column 1141 arranged on the side wall of the temporary storage cavity 114 and extending towards the baffle 123. The door opening column 1141 is adapted to push the baffle 123 to rotate to open the liquid outlet 122 when the bucket 12 is in the first position.

[0042] The door opening column 1141 can be simply understood as a driving device for driving the baffle 123 to rotate. The door opening column 1141 is arranged on the side wall of the temporary storage cavity 114 and extends towards the baffle 123. When the bucket 12 moves to the first position, the baffle 123 is in contact with the door opening column 1141 and is pushed open by the door opening column 1141 by a certain angle. It can also be understood that during at least part of the movement of the bucket 12 to the first position, the baffle 123 is in contact with the door opening column 1141 and is driven to rotate by a certain angle under the action of the door opening column 1141 to realize the rotation of the baffle 123 to open the liquid outlet 122. The arrangement of the door opening column 1141 makes the rotation of the baffle 123 more automatic, simplifies the operation process of opening the liquid outlet 122, and enables the washing material in the pouring cavity 121 to flow into the temporary storage cavity 114 without manual operation, thereby improving the automation degree of the shower head body assembly 1 and the convenience during use.

[0043] According to some embodiments of the present application, the foam generating device 13 is located below the bucket 12, and the foam generating device 13 is provided with a liquid inlet 134 for communicating the foam generating device 13 with the temporary storage cavity 114. When the bucket 12 is received in the housing 11, at least part of the foam generating device 13 is located below the bucket 12. Such a layout design makes the structure of the shower head body assembly 1 more compact. The foam generating device 13 is provided with the liquid inlet 134, which can be in communication with the opening at the bottom of the temporary storage cavity 114. The washing material entering the temporary storage cavity 114 can enter the foam generating device 13 through the liquid inlet 134. The arrangement of the liquid inlet 134 realizes the communication relationship between the temporary storage cavity 114 and the foam generating device 13.

[0044] According to some embodiments of the present application, the housing 11 is provided with a water inlet end 111 and a liquid outlet end 112, and the foam generating device 13 comprises a first section 131 and a second section 132. One end of the first section 131 is in communication with the water inlet end 111. One end of the second section 132 is in communication with the other end of the first section 131, and the other end of the second section 132 is in communication with the liquid outlet end 112. The second section 132 is provided with a liquid inlet 134. The diameter of the second section 132 is smaller than the diameter of the first section 131.

[0045] Since the foam generating device 13 is a structure for guiding the foaming of the washing material, the configuration of the foam generating device 13 will affect the foaming effect. In some embodiments, the foam generating device 13 is provided with a first section 131 and a second section 132 connected with each other, wherein the first section 131 is in communication with the water inlet end 111; the second section 132 is in communication with the first section 131 and the liquid outlet end 112, and the second section 132 is provided with a liquid inlet 134 in communication with the temporary storage cavity 114. When the hopper 12 moves to the first position, the washing material in the dropping cavity 121 flows into the second section 132 through the temporary storage and the liquid inlet 134, and the washing material entering the second section 132 can be mixed with the water introduced by the first section 131 and foamed. In this process, since the diameter of the first section 131 is greater than the diameter of the second section 132, the flow rate of the mixed liquid in the second section 132 will be accelerated and foam will be generated. Since the foam has better coverage and permeability, the same amount of washing material in the foam generating device 13 can generate more foam compared to directly putting the washing material into the object to be washed, thereby improving the washing effect of the shower head body assembly 1.

[0046] According to some embodiments of the present application, the foam generating device 13 further comprises a third section 133, one end of the third section 133 is in communication with the other end of the second section 132, the other end of the third section 133 is in communication with the liquid outlet end 112, and the diameter of the second section 132 is smaller than the diameter 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 greater than the diameter 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 have more time and space to grow stably, and a more persistent and stable foam can be formed, thereby improving the foam quality, reducing the possibility of foam breaking during the flow process, and further ensuring the washing effect of the shower head body assembly 1.

[0047] According to some embodiments of the present application, the second section 132 is further provided with an air suction port 135, the air suction port 135 is in communication with the outside of the foam generating device 13, and the air suction port 135 at least partially faces the liquid inlet 134 in the radial direction of the second section 132. Since the diameter of the second section 132 is smaller than the diameter of the first section 131 and the third section 133, the flow rate of the mixed liquid in the second section 132 is faster, thereby forming a low-pressure area in the second section 132. At this time, by providing the air suction port 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 abundant foam and 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, thereby improving the foaming quality of the foam generating device 13.

[0048] In addition, the air inlet 135 and the liquid inlet 134 can be at least partially opposite, since the air inlet 135 is at least partially opposite to the liquid inlet hole in the radial direction of the second section 132, when the washing medium flows into the second section 132 through the liquid inlet hole, the external air can directly enter the second section 132 through the air inlet 135, and the air and the washing medium enter the second section 132 at the same time, which ensures that the air and the mixed liquid can be fully contacted and mixed in the foam generating device 13, thereby generating more stable foam.

[0049] According to some embodiments of the present application, the shell 11 comprises an outer shell 116, an inner shell 117, and a baffle 118, the outer shell 116 is formed with a containing cavity 113 inside; the inner shell 117 is arranged in the containing cavity 113 and defines a water outlet cavity 1171 open 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 arranged at the opening of the water outlet cavity 1171 and is used to block the mixed liquid guided by the water outlet cavity 1171.

[0050] As shown in FIG. 7, the shell 11 can be simply divided into an outer shell 116 and an inner shell 117, wherein the outer shell 116 is formed with a containing cavity 113 inside which can accommodate the bucket 12; the inner shell 117 is arranged in the containing cavity 113, which can be understood in FIG. 7 as the inner shell 117 being arranged at the bottom wall of the containing cavity 113, the inner shell 117 defines a water outlet cavity 1171 open toward the liquid outlet end 112 and communicating with the liquid outlet end 112 in the containing cavity 113, the outlet of the third section 133 is located in the water outlet cavity 1171, thus the mixed liquid flowing out of the third section 133 first flows into the water outlet cavity 1171 and then to the liquid outlet end 112, the opening of the water outlet cavity 1171 is provided with a baffle 118, the baffle 118 closes at least part of the opening of the water outlet cavity 1171, thus 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 foam mixed liquid flowing out of the third section 133 has a high speed, the water outlet cavity 1171 can buffer the foam mixed liquid, reduce the possibility of the foam breaking, and ensure the washing effect of the final mixed liquid.

[0051] In some embodiments, a workbench can be arranged on the clothes treatment apparatus, and the spray head body assembly 1 can be assembled on the workbench, and the arrangement of the workbench can integrate the spray head body assembly 1 and the operation unit of the clothes treatment apparatus into the same structure, which is convenient for the user to operate.

[0052] In some embodiments, as shown in FIG. 12, a guide inclined surface 11821 can be machined on the second matching part 1182, which can guide the matching of the first matching part 1172 and the second matching part 1182, and improve the assembly efficiency of the baffle 118.

[0053] According to some embodiments of the present application, the inner shell 117 is provided with first matching parts 1172 on both sides in the width direction, the baffle 118 comprises a plate body 1181 and second matching parts 1182, the plate body 1181 extends in the width direction of the inner shell 117 to close at least part of the open port of the water outlet cavity 1171; the second matching parts 1182 are arranged at both ends of the plate body 1181 in the extending direction and are adapted to match with the first matching parts 1172; wherein the first matching parts 1172 are configured as mounting holes, and the second matching parts 1182 are configured as mounting protrusions which can extend into the mounting holes.

[0054] As shown in FIG. 11, the main part of the baffle 118 is configured as the plate body 1181, and the plate body 1181 is provided with the second matching parts 1182 at both ends in the width direction shown in FIG. 7. Correspondingly, as shown in FIG. 7, the inner shell 117 is provided with the first matching parts 1172 on both side walls in the width direction, and the first matching parts 1172 can match with the second matching parts 1182 to realize the assembly and fixation of the baffle 118, thereby ensuring the stability of the baffle 118 after being assembled to the open port of the inner shell 117.

[0055] In some embodiments, the first matching parts 1172 are configured as mounting holes, and the second matching parts 1182 are configured as mounting protrusions which can extend into the mounting holes. During assembly, the mounting protrusions can be accommodated in the mounting holes, and the side surface of the mounting protrusions can abut against the side wall of the mounting holes, thereby further improving the stability of the assembly of the baffle 118.

[0056] In some embodiments, as shown in FIG. 12, the mounting protrusions are provided with guide inclined surfaces 11821. The guide inclined surfaces 11821 can guide the matching of the first matching parts 1172 and the second matching parts 1182, thereby improving the assembly efficiency of the baffle 118.

[0057] According to some embodiments of the present application, 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 limit cooperation with the first limiting portion 1173; wherein the first limiting portion 1173 is arranged on the inner shell 117 and extends towards the baffle plate 118, and one end of the first limiting portion 1173 towards the baffle plate 118 is formed with a stop surface 1174; the second limiting portion 1183 is arranged on at least one end of the plate body 1181 in the height direction of the shower head body assembly 1 and extends towards the first limiting portion 1173. Since the function of the baffle plate 118 is to block the foam mixture in the water outlet cavity 1171 and change the flow direction of the foam mixture, the baffle plate 118 cannot rotate. In some embodiments, 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, which can also be understood as the second limiting portion 1183 being arranged towards each other and being stopped. After the baffle plate 118 is assembled with the inner shell 117, the first limiting portion 1173 and the second limiting portion 1183 limit cooperation, which limits the rotation of the baffle plate 118 in the clockwise direction shown in FIG. 11, so that the baffle plate 118 achieves the effect of blocking the flow.

[0058] In some embodiments, the first limiting portion 1173 is arranged on the inner shell 117 and extends towards the baffle plate 118, and one end of the first limiting portion 1173 towards the baffle plate 118 is formed with a stop surface 1174; the second limiting portion 1183 is arranged on one end of the plate body 1181 in the height direction of the shower head body assembly 1 and extends towards the first limiting portion 1173, and the second limiting portion 1183 is adapted to stop with the stop surface 1174.

When the baffle plate 118 is fixed, the second limiting portion 1183 stops with the stop surface 1174, and the arrangement of the stop surface 1174 can increase the cooperation area when the first limiting portion 1173 and the second limiting portion 1183 stop, thereby improving the stability when the first limiting portion 1173 and the second limiting portion 1183 stop.

[0060] In some embodiments, the plate body 1181 is provided with a third limiting portion 1184 at the other end in the height direction of the nozzle body assembly 1, which extends towards the liquid outlet end 112 to limit the rotation of the flow baffle 118. As shown in FIG. 7 and FIG. 11, the plate body 1181 is provided with a second limiting portion 1183 at one end in the height direction, and a third limiting portion 1184 at the other end, which extends in a direction away from the water outlet cavity 1171. When the flow baffle 118 is assembled, the third limiting portion 1184 can abut against the bottom wall of the containing cavity 113 to limit the rotation of the flow baffle 118 in the counterclockwise direction as shown in FIG. 11, so as to facilitate the flow baffle 118 to block the foam mixture in the water outlet cavity 1171.

[0061] According to some embodiments of the present application, the water outlet cavity 1171 is provided with a first flow converging plate 141 and a second flow converging plate 142 extending towards each other at both sides in the width direction, and a flow converging area 143 is defined between the first flow converging plate 141 and the second flow converging plate 142, and the outlet of the flow converging area 143 communicates with the liquid outlet end 112.

[0062] As shown in FIG. 9, the water outlet cavity 1171 is provided with a first flow converging plate 141 and a second flow converging plate 142 at both sides in the width direction, and the first flow converging plate 141 and the second flow converging plate 142 extend towards each other to define a flow converging area 143. The mixture overflowing from the pouring cavity 121, the foam mixture flowing out of the water outlet cavity 1171, or the mixture flowing out of other positions in the shell 11 can all converge in the flow converging area 143. By defining the flow converging area 143, the mixture can be controlled to converge, so that the mixture flowing out of the liquid outlet end 112 can more evenly cover the objects to be washed or specific areas that need to be cleaned, and the poor cleaning effect or resource waste caused by uneven distribution of the mixture can be avoided.

[0063] In addition, the first flow converging plate 141 and the second flow converging 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.

[0064] According to some embodiments of the present application, the shell 11 is formed with a containing cavity 113 extending in the front-rear direction, and the hopper 12 is movably arranged in the containing cavity 113, and the temporary storage cavity 114 is arranged at the rear side of the containing cavity 113. The containing cavity 113 can extend in the front-rear direction of the shell 11, and the front-rear direction here can also be understood as the direction in which the hopper 12 moves, and the temporary storage cavity 114 is arranged at the rear side of the containing cavity 113. Such layout design can improve the structural compactness of the nozzle body assembly 1, and also can make the conduction state between the pouring cavity 121 and the temporary storage cavity 114 more stable.

[0065] According to some embodiments of the present application, the foam generating device 13 is arranged in the housing 11 and below the temporary storage cavity 114, and the foam generating device 13 is provided with a liquid inlet 134 which is in communication with the temporary storage cavity 114. When the bucket 12 is received in the housing 11, at least part of the foam generating device 13 is below the bucket 12, and such arrangement makes the structure of the spray head body assembly 1 more compact. The foam generating device 13 is provided with the liquid inlet 134, and the liquid inlet 134 can be in communication with the opening at the bottom of the temporary storage cavity 114, and the washing agent entering the temporary storage cavity 114 can enter the foam generating device 13 through the liquid inlet 134. The arrangement of the liquid inlet 134 realizes the communication relationship between the temporary storage cavity 114 and the foam generating device 13.

[0066] According to some embodiments of the present application, the diameter of the second section 132 is d1, the diameter of the liquid inlet 134 is d2, and 0.4≤d2 / d1≤0.45 is satisfied; the diameter of the air inlet 135 is d3, and 0.45≤d3 / d1≤0.55 is satisfied; the diameter of the first section 131 and the third section 133 is d4, and 0.35≤d4 / d1≤0.45 is satisfied.

[0067] The diameter of the second section 132 is d1, and the diameter of the liquid inlet 134 is d2, and 0.4≤d2 / d1≤0.45 is satisfied. Since the liquid inlet 134 is arranged on the second section 132, the size relationship between the liquid inlet 134 and the second section 132 will affect the generation of foam. In some embodiments, if the diameter of the second section 132 is d1, and the diameter of the liquid inlet 134 is d2, 0.4≤d2 / d1≤0.45 is satisfied. When d2 / d1<0.4, the diameter of the liquid inlet 134 is smaller than the diameter of the second section 132, at this time, the amount of washing agent entering the main flow path through the liquid inlet 134 is small, which will cause the washing agent in the main flow path to be insufficient, which will reduce the generated foam, and thus will cause the washing effect to decrease; when d2 / d1>0.45, the diameter of the liquid inlet 134 is larger than the diameter of the second section 132, at this time, the amount of washing agent entering the main flow path through the liquid inlet 134 is large, which will cause the washing agent in the main flow path to be excessive, and the excessive washing agent cannot foam in time before flowing out of the foam generating device 13 due to the limited size of the main flow path, which will cause the washing effect to decrease. 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 can be 0.43, and when d2 / d1=0.43, the foaming effect is better than other values.

[0068] If the diameter of the second section 132 is d1 and the diameter of the air inlet 135 is d3, it is satisfied that 0.45≤d3 / d1≤0.55. Since the air inlet 135 is arranged on the second section 132, the size relationship between the air inlet 135 and the second section 132 will affect the generation of the foam. In some embodiments, if the diameter of the second section 132 is d1 and the diameter of the air inlet 135 is d3, it is satisfied that 0.45≤d3 / d1≤0.55. When d3 / d1<0.45, the diameter of the air inlet 135 is smaller than 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 the gas mixed with the mixed liquid in the foam generating device 13 to be insufficient, which will reduce the quality and the amount of the generated foam, and further will cause the washing effect to be reduced. When d3 / d1>0.55, the diameter of the air inlet 135 is larger than the diameter of the second section 132, at this time, the air inlet 135 with the too large size is easy to cause the mixed liquid to leak from the air inlet 135. Therefore, the ratio of the diameter of the air inlet 135 to the diameter of the second section 132 should be in a relatively appropriate range, for example, d3 / d1 can be 0.5, when d3 / d1=0.5, the sealing performance is ensured at the same time, and the foaming effect is better than other values.

[0069] If the diameter of the second section 132 is d1, the diameter of the first section 131 and the diameter of the third section 133 are both d4, it is satisfied that 0.35≤d1 / d4≤0.45. Since the second section 132 is arranged between the first section 131 and the third section 133, and the second section 132 is configured as a variable diameter section, the relationship between the diameter of the second section 132 and the diameter of the third section 133 will affect the foaming effect of the mixed liquid in the foam generating device 13. When d1 / d4<0.35, the second section 132 is too small compared to the third section 133, at this time, the flow rate in the second section 132 is too fast, and the washing material and water entering the second section 132 cannot be mixed completely in time, which will cause the generated foam to be reduced. When d1 / d4>0.45, the second section 132 is too large compared to the third section 133, at this time, the flow rate change between the second section 132 and the third section 133 is small, and the washing material and water are fully mixed due to the small flow rate change on the flow path, which will cause the mixed liquid to be stable, and further will cause the generated foam to be small. Therefore, 0.35≤d1 / d4≤0.45 is a relatively appropriate range, in which range, d1 / d4 can be 0.4. It should be noted that the diameter of the first section 131 and the diameter of the third section 133 can be the same.

[0070] In some embodiments, as shown in FIG. 1, a liquid outlet 122 is formed on the side wall of the delivery cavity 121 on the side of the delivery cavity 121 facing the temporary storage cavity 114, the liquid outlet 122 is opposite to the opening of the temporary storage cavity 114, and the liquid outlet 122 and the temporary storage cavity 114 are in communication. The liquid outlet 122 is provided with a baffle 123, and the baffle 123 can rotate at the position of the liquid outlet 122 to close or open the liquid outlet 122. The baffle 123 is arranged so that the communication relationship between the liquid outlet 122 and the temporary storage cavity 114 is controllable. When the bucket 12 is accommodated in the shell 11, the baffle 123 can be rotated and the liquid outlet 122 is opened to make the delivery cavity 121 and the temporary storage cavity 114 in communication; when the bucket 12 is located at other positions, the baffle 123 closes the liquid outlet 122. The arrangement of the baffle 123 also avoids the leakage of the washing material in the delivery cavity 121. The side wall of the temporary storage cavity 114 is provided with a door opening column 1141, which extends towards the liquid outlet 122. When the bucket 12 moves into the shell 11, the door opening column 1141 can push the baffle 123 to rotate. The door opening column 1141 can be understood as a driving device for driving the baffle 123 to rotate. The arrangement of the door opening column 1141 makes the rotation of the baffle 123 automatic, that is, the communication between the delivery cavity 121 and the temporary storage cavity 114 is automatic, without the need for manual operation of the user, thereby improving the user experience.

[0071] According to some embodiments of the present application, the nozzle body assembly 1 for the clothes treatment apparatus further comprises a first water path, the first water path is in communication with the water inlet end 111 and the liquid outlet end 112, and the first water path is further provided with a foam generating device 13. The first water path comprises a water inlet channel 115, the inlet of the water inlet channel 115 is in communication with the water inlet end 111, the outlet of the water inlet channel 115 is in communication with one end of the first section 131, and the water inlet channel 115 and the temporary storage cavity 114 are arranged in the moving direction of the bucket 12. The shell 11 is provided with the water inlet end 111 and the liquid outlet end 112, the shell 11 forms a first water path in communication with the water inlet end 111 and the liquid outlet end 112, and the foam generating device 13 is arranged in the first water path.

[0072] The shell 11 is provided with a liquid outlet end 112 and a water inlet end 111. The water inlet end 111 is connected to an external water source to introduce water into the shell 11. The liquid outlet end 112 can be understood as an outlet of the spray head body assembly 1. A first water channel is formed in the shell 11 to connect the water inlet end 111 and the liquid outlet end 112 and pass through the foam generating device 13. The inlet of the foam generating device 13 is connected to the inlet of the first water channel, and the outlet of the foam generating device 13 is connected to the outlet of the first water channel. The water introduced by the water inlet end 111 can enter the foam generating device 13 through the first water channel, and the water entering the foam generating device 13 can be mixed with the cleaning agent 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 of the outlet of the foam generating device 13, flows to the liquid outlet end 112, and finally flows out of the spray head body assembly 1 through the liquid outlet end 112 to clean the objects to be washed. The first water channel cooperates with the foam generating device 13 to generate foam in the mixed liquid of the cleaning agent, thereby improving the cleaning effect of the spray head body assembly 1.

[0073] In some embodiments, the first water channel can be understood as a water inlet channel 115 between the water inlet end 111 and the inlet of the foam generating device 13. The water inlet channel 115 and the temporary storage cavity 114 are arranged in sequence in the moving direction of the bucket 12, and the water inlet channel 115 is arranged on the side of the temporary storage cavity 114 away from the bucket 12. 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 arranged on the side of the temporary storage cavity 114 away from the bucket 12, which can avoid the influence of the movement of the bucket 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 in the water inlet channel 115 entering the foam generating device 13, thereby ensuring the continuous generation of foam.

[0074] According to some embodiments of the present application, the nozzle body assembly 1 for the clothes treatment apparatus further comprises a second water path 16, which is arranged on the upper surface of the housing 11 and spaced apart from at least part of the water inlet channel 115, the inlet of the second water path 16 is in communication with the water inlet end 111, and the outlet of the second water path 16 is in communication with the dispensing cavity 121. In some embodiments, the second water path 16 is further arranged on the nozzle body assembly 1, and the second water path 16 also communicates the water inlet end 111 and the liquid outlet end 112. Unlike the first water path flowing through the foam generating device 13, the second water path 16 flows through the dispensing cavity 121, and part of the water flow entering the water inlet end 111 can directly flow into the dispensing cavity 121 through the second water path, and the water entering the dispensing cavity 121 can overflow from at least part of the side wall of the dispensing cavity 121 after mixing with the washing material and flow to the liquid outlet end 112. Unlike the first water path, there is no foam generating device 13 in the second water path 16, and the water in the second water path 16 is directly mixed with the washing material in the dispensing cavity 121 and then used to clean the to-be-washed material. The cleaning method of the second water path 16 is suitable for the case where the to-be-washed material has less stains, and such a cleaning method can further simplify the operation process on the premise of meeting the cleaning demand.

[0075] In addition, the second water path 16 is arranged on the surface of the housing 11 and spaced apart from at least part of the water inlet channel 115, so that the first water path and the second water path 16 are arranged more compactly in the housing 11, which can reduce the volume of the nozzle body assembly 1 and facilitate the arrangement of the nozzle body assembly 1.

[0076] According to some embodiments of the present application, the second water path 16 is spaced apart from a plurality of water inlet holes 161 in the extension direction, and the plurality of water inlet holes 161 are in communication with the dispensing cavity 121, and the plurality of water inlet holes 161 are configured as the outlet of the second water path 16. In some embodiments, the second water path 16 is arranged on the upper surface of the housing 11 and spaced apart from a plurality of water inlet holes 161, and each water inlet hole 161 is in communication with the dispensing cavity 121. As shown in FIG. 9, the arrangement of the plurality of water inlet holes 161 allows the water in the second water path 16 to enter the dispensing cavity 121 from a plurality of different positions, which improves the rate at which water enters the dispensing cavity 121. At the same time, when the water in the second water path 16 enters the dispensing cavity 121 from the plurality of water inlet holes 161, it can impact the washing material in the dispensing cavity 121 and mix the washing material with the water to generate foam, which can increase the foam content of the mixed liquid overflowing from the dispensing cavity 121, and improve the washing effect of the mixed liquid flowing out through the liquid outlet end 112 after flowing from the second water path 16 to the dispensing cavity 121.

[0077] In some embodiments, the first waterway and the second waterway 16 can flow simultaneously, for example, on-off valves can be installed at the connection position of the water inlet end 111 and the first waterway and the connection position of the water inlet end 111 and the second waterway 16 respectively, and the on-off valves can be used to select and control the on or off state of the first waterway and the second waterway 16 respectively. The on-off valves can be designed in different ways to provide different liquid outlet options for the spray head body assembly 1, for example, the first waterway and the second waterway 16 can be selected to be on or off respectively or to be on simultaneously. Different options can provide different washing effects for the spray head body assembly 1, and the appropriate option can be selected according to the washing requirements, thereby improving the flexibility and controllability of the spray head body assembly 1.

[0078] In some embodiments, the accommodation cavity 113 can extend in the front-rear direction, and the front-rear direction can also be understood as the moving direction of the drawer 12. The temporary storage cavity 114 is arranged at the rear side of the accommodation cavity 113. Such a layout design can improve the compactness of the spray head body assembly 1 and can also make the on state of the connection between the delivery cavity 121 and the temporary storage cavity 114 more stable.

[0079] The laundry treating apparatus according to the present application will be described below.

[0080] The laundry treating apparatus according to the present application includes the spray head body assembly 1 for the laundry treating apparatus in the above-described embodiments. Since the laundry treating apparatus according to the present application is provided with the spray head body assembly 1 for the laundry treating apparatus in the above-described embodiments, the washing effect and user experience of the laundry treating apparatus are better.

[0081] In some embodiments, 2.5 mm≤d1≤3.5 mm. Since the size of d1 can affect the flow rate of the washing material and water in the second section 132, d1 needs to be kept in a suitable range. In some embodiments, when d1<2.5 mm, the diameter of the second section 132 is too small, at this time, the flow rate of the washing material and water in the second section 132 is too fast, the washing material and water are difficult to mix fully, the foam generated by the foam generating device 13 is less, which can cause the cleaning effect of the foam generating device 13 to decrease; when d1>3.5 mm, the diameter of the liquid inlet 134 is too large, at this time, the flow rate of the washing material and water in the second section 132 is too slow, and the mixed liquid after full mixing has low flow rate and small impact force, and the generated foam is also less. Therefore, 2.5 mm≤d1≤3.5 mm is a more suitable range, and in this range, d1 can be 3 mm.

[0082] In some embodiments, 1mm≤d2≤1.5mm. Since the size of d2 will affect the washing material into the second section 132, d2 needs to be kept in a suitable range. In some embodiments, when d2<1mm, the inlet 134 is too small in diameter, at this time, the rate of washing material into the second section 132 is low, the foam generated by the foam generating device 13 is less, which will cause the cleaning effect of the foam generating device 13 to be reduced; when d2>1.5mm, the inlet 134 is too large in diameter, at this time, the efficiency of the washing material into the second section 132 is too fast, and too much washing material enters the foam generating device 13, which will cause the waste of washing material and increase the cost. Therefore, 1mm≤d2≤1.5mm is a more suitable range, and in this range, d2 can be 1.3mm.

[0083] In some embodiments, 1.2mm≤d3≤2mm. Since the diameter of the air inlet 135 will affect the air entering the foam generating device 13, the diameter of the air inlet 135 needs to be set within a suitable range. In some embodiments, when d3<1.2mm, the air inlet 135 is too small in diameter, at this time, the rate of air entering the second section 132 is low, and the intervention of air is lacking, the foam generated by the foam generating device 13 is less, which will cause the cleaning effect of the foam generating device 13 to be reduced; when d3>2mm, the washing material and water are easy to leak from the air inlet 135. Therefore, 1.2mm≤d3≤2mm is a more suitable range, and in this range, d3 can be 1.3mm.

[0084] In some embodiments, a sink 1213 is formed on the bottom wall of the delivery cavity 121, and a siphon device 15 can be arranged in the sink 1213, as shown in FIGS. 8 and 10. The outlet of the siphon device 15 communicates with the confluence area 143. The siphon device 15 can discharge the residual washing material in the delivery cavity 121 and the water introduced into the delivery cavity 121 by the second waterway 16 by siphoning, and be used for washing clothes, avoiding the residual washing material and water in the delivery cavity 121, and effectively avoiding the problem of secondary pollution of the delivery cavity 121 caused by the residual material. In this process, the sink 1213 is designed to improve the ability of the siphon device 15 to siphon the residual washing material and water in the delivery cavity 121.

[0085] In some embodiments, as shown in FIG. 10, 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 is formed in the siphon pipe 151 to communicate the drop chamber 121 with the confluence area 143; the siphon cylinder 152 is arranged on 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 is left between the siphon cylinder 152 and the bottom wall of the sink 1213 to communicate the drop chamber 121 with the second siphon waterway 1521.

[0086] In some embodiments, the siphon pipe 151 is arranged on the bottom wall of the sink 1213, and the siphon cylinder 152 is arranged on the outer periphery of the siphon pipe 151 to facilitate the formation of the siphon gap 153 at the bottom wall of the sink 1213, and the residual water and washing materials in the drop chamber 121 can sequentially pass through the second siphon waterway 1521 and the first siphon waterway 1511 and then flow into the confluence area 143, and the arrangement position and internal structure of the siphon device 15 ensure that the siphon device 15 can remove the residues at the bottom of the drop chamber 121, thereby improving the siphon effect.

[0087] In some embodiments, at least part of the side wall of the drop chamber 121 is formed with a water outlet 1214, which can also be simply understood as that at least one side wall of the drop chamber 121 is lower than the adjacent side wall to form the water outlet 1214, and the water in the first waterway can directly overflow to the confluence area 143 through the water outlet 1214 after mixing with the washing materials in the drop chamber 121.

[0088] In some embodiments, the drop chamber 121 includes a first chamber 1211 and a second chamber 1212, and the first chamber 1211 and the second chamber 1212 respectively communicate the water inlet end 111 and the liquid outlet end 112, and the first chamber 1211 and the second chamber 1212 can be used to accommodate the washing materials, such as detergents and disinfectants.

[0089] In some embodiments, the drop assembly further includes an identification plate 17 extending towards the inside of the drop chamber 121 on the siphon cylinder 152, and a scale mark 171 is arranged on the identification plate 17, the position of the scale mark 171 is not higher than the lowest side wall of the drop chamber 121, or the scale mark 171 is not higher than the standardized maximum drop height of the washing materials in the drop chamber 121. When the user drops the washing materials, the amount of the dropped washing materials can be intuitively judged by the scale mark 171, so as to avoid the washing materials overflowing from the side wall or other positions of the drop chamber 121 to affect the washing effect, and the scale mark 171 can improve the user experience.

[0090] In summary, the spray head body assembly 1 is provided with an inner shell 117 and an outer shell 116, the outer shell 116 is formed with a containing cavity 113, the hopper 12 is movably arranged in the containing cavity 113, and the inner shell 117 is arranged in the containing cavity 113 and located at the lower part of the hopper 12, thereby improving the compactness of the structure of the spray head 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, and the opening of the water outlet cavity 1171 is provided with a flow baffle 118, which can block the flow of the foam mixture in the water outlet cavity 1171, reduce the flow speed of the foam mixture, and further reduce the possibility of the foam breaking, so as to ensure the washing effect of the mixture flowing out of the final liquid outlet 112. The water outlet cavity 1171 is provided with at least two flow converging plates facing each other on both sides in the width direction, and the water and washing substances entering the spray head body assembly 1 are finally converged in the flow converging area 143 and then flow out through the liquid outlet 112, so that the mixture sprayed out of the spray head body assembly 1 is more uniform. The foam generating device 13 is provided with a liquid inlet 134 and an air inlet 135 which at least partially face each other in the radial direction of the second section 132, the liquid inlet 134 is in communication with the temporary storage cavity 114, and the air inlet 135 is in communication with the outside air. At the same time, the temporary storage cavity 114 can realize the communication between the dispensing cavity 121 and the temporary storage cavity 114 when the hopper 12 is in the first position through the cooperation between the baffle 123 located at the liquid outlet 122 of the dispensing cavity 121 and the door opening column 1141, so that the washing substances in the dispensing cavity 121 can enter the foam generating device 13 for foaming after passing through the temporary storage cavity 114, thereby improving the washing effect of the spray head body assembly 1. The water inlet end 111 in the dispensing cavity 121 is connected through the second water path 16, and the foam generating device 13 is connected with the water inlet end 111 through the water inlet channel 115 in the first water path.
