The main body 1 is internally provided with a cavity 11, the main body 1 is provided with a water inlet hole 12 communicated with the cavity 11, and the water inlet hole 12 is communicated at two ends of the extending direction. One end of the water inlet 12 is communicated with the cavity 11 in the main body 1, the other end of the water inlet 12 is communicated with the outside of the nozzle body assembly, and the water inlet 12 can be used for guiding water flow into the cavity 11. The cavity 11 can be used for containing treatment substances such as washing powder, liquid laundry detergent, softener, disinfectant and the like, the water inlet 12 can guide water into the cavity 11 from the outside of the nozzle body assembly, so that the water flow and the treatment substances are mixed and diluted, and the mixed and diluted liquid is guided out of the nozzle body assembly. In the case that the spray head body assembly is provided in the laundry treating apparatus, the diluted liquid guided out from the spray head body assembly may be discharged into the washing tub for washing laundry. The user may also replenish the treatment substance within the cavity 11.

In the embodiment of the present invention, as shown in fig. 2, the impeller 3 includes a rotation shaft 31 and blades 32. The vane 32 is provided on the rotation shaft 31. The shaft 31 is rotatably disposed in the cavity 11, and it should be noted that the embodiment of the present invention is not limited to a specific connection relationship between the shaft 31 and other components in the nozzle assembly, for example, the shaft 31 may be rotatably connected to the main body 1, and of course, the shaft 31 may also be rotatably connected to other components, no matter what component the shaft 31 has a direct connection relationship with, as long as the shaft 31 can rotate relative to the cavity 11. During rotation of the shaft 31, the blades 32 and the shaft 31 stir the mixture of the water and the treatment substance in the cavity 11 together, so that the water and the treatment substance in the cavity 11 are uniformly mixed.

In the embodiment of the present invention, the vane 32 may intersect with the extending direction of the water inlet 12, wherein the water inlet 12 is used for guiding water into the cavity 11, and the water is an indefinite shape fluid, and then the flowing direction of the water is related to the extending direction of the water inlet 12, and the moving direction of the water entering the cavity 11 is limited by the extending direction of the water inlet 12 besides the action of gravity, and the extending direction of the water inlet 12 can be understood as the length direction of the water inlet 12.

The water impacting on the blades 32 has a certain kinetic energy and potential energy, and in the process of contacting the water with the blades 32, the water transfers energy to the blades 32 and converts the energy into the kinetic energy of the blades 32, and the blades 32 can drive the rotating shaft 31 to move in the cavity 11. It should be noted that, the relative movement of the rotating shaft 31 and the cavity 11 includes rotation and translation. The movement mode relates to the specific connection mode of the rotating shaft 31 and the main body 1, and the embodiment of the invention is not limited.

As shown in fig. 2, the transmission assembly 4 is rotatably connected with the rotating shaft 31, the main body 1 is provided with a sliding rail 26, the transmission assembly 4 can rotate along with the rotation of the impeller 3, and the impeller 3 can be driven to slide along the sliding rail 26 in the process of rotating the transmission assembly 4. It should be noted that the embodiment of the present invention is not limited to the specific structure of the transmission assembly 4, as long as the transmission assembly 4 can slide along the sliding rail 26 under the force. The embodiment of the invention does not limit the specific position where the transmission assembly 4 is arranged, the transmission assembly 4 can be arranged in the cavity 11, and the transmission assembly 4 can also be arranged outside the main body 1, so long as the transmission assembly 4 can drive the impeller to slide in the process of rotating the impeller.

The spray head body assembly provided by the embodiment of the invention comprises a main body, an impeller and a transmission assembly; the main body is internally provided with a cavity and a plurality of water inlets, and the impeller is arranged in the cavity and can intersect with the extending direction of the water inlets, so that water flowing into the water inlets can impact the impeller to rotate and stir substances in the cavity; the transmission assembly is rotatably connected with the impeller, so that the transmission assembly can rotate along with the rotation of the impeller, and the rotation of the transmission assembly can drive the impeller to slide. According to the embodiment of the invention, the impeller and the transmission assembly are arranged, so that water flowing into the cavity from the water inlet hole can impact the impeller to rotate, and the impeller is driven to slide through the transmission of the transmission assembly, so that the impeller can move to each position in the cavity, washing substances held in each position in the cavity are sufficiently stirred, the possibility that the washing substances remain in the cavity and are insufficiently dissolved is reduced, and the cleaning effect is improved.

The drawer 2 is pulled out of the cavity 11 of the body 1 and the treatment substance is replenished into the holding chamber 21 from the opening 25 of the drawer 2. The accommodating cavity 21 can be used for accommodating treatment substances such as washing powder, laundry detergent, softener, disinfectant and the like, the water inlet 12 can guide water into the accommodating cavity 21 from the outside of the spray head body assembly, so that the water flow and the treatment substances are mixed and diluted, and the mixed and diluted liquid is guided out of the spray head body assembly. Wherein at least one of the housing 10 and the drawer 2 is provided with a slide rail 26. The impeller 3 is at least partially located in the accommodating chamber 21, that is, the vane 32 may be partially disposed in the accommodating chamber 21 and partially disposed outside the accommodating chamber 21, for example, the accommodating chamber 21 is low in height and the cavity 11 is higher than the accommodating chamber 21 in height, so that the vane 32 may be rotated to an upper end position to protrude above the accommodating chamber 21; of course, the blades may be disposed entirely in the housing chamber 21, for example, the housing chamber 21 may have a high height. In the process that the rotating shaft 31 rotates relative to the accommodating cavity 21, the blades 32 rotate along with the rotating shaft 31, so that the relative positions of the blades 32 and the accommodating cavity 21 also change, the same blade 32 can have different positional relationships with the accommodating cavity 21 at different moments, for example, the blades 32 can be positioned in the accommodating cavity 21 at the first moment, and after the blades 32 rotate along with the rotating shaft 31 at the next moment, the blades 32 can be positioned outside the accommodating cavity 21, and it is understood that at least part of the blades 32 described in the embodiment of the invention are positioned in the accommodating cavity 21, and at the same moment, part of the blades 32 on the same rotating shaft 31 can be positioned in the accommodating cavity 21, and the other part of the blades 32 can be positioned outside the accommodating cavity 21; of course, it is also understood that the same vane 32 is positioned within the receiving chamber 21 during at least a portion of the rotation of the same vane 32 following the rotation of the shaft 31.

In some embodiments, as shown in fig. 2, the drawer 2 includes two first side walls 22 on opposite sides of the receiving cavity 21, the first side walls 22 extending in a first direction (x-direction in fig. 2), each first side wall 22 being provided with a sliding track 26 extending in the first direction. The first side walls 22 are positioned at both ends of the receiving chamber 21 in the second direction (y direction shown in fig. 2), and the first side walls 22 may extend along a plane formed by the x direction and the z direction. In one embodiment, the sliding track in one of the first side walls 22 is perforated with a first through hole 23, the first through hole 23 extending in a first direction (x-direction shown in fig. 2). The rotating shaft 31 extends in the second direction (y direction shown in fig. 2) in the accommodating chamber 21, one end (one end in y direction in fig. 2) of the rotating shaft 31 passes through the first through hole 23 of the first side wall 22, and one end of the rotating shaft 31 can slide along the first through hole 23; the other first side wall 22 is provided with a slide rail 26 extending in a first direction (x direction shown in fig. 2) on a wall surface of the adjacent accommodating chamber 21, and the other end of the rotating shaft 31 is provided in the slide rail 26, and the other end of the rotating shaft 31 is slidable along the slide rail 26. A slide rail 26 is provided in the first side wall 22 on the side close to the receiving chamber to facilitate engagement with the spindle.

In some embodiments, the sliding rail 26 penetrates the other first side wall 22 to become the first through hole 23. That is, the sliding rail may be provided to penetrate the first through holes 23 at opposite sides of the first side wall, wherein both the first side walls 22 are provided to penetrate the first through holes 23 such that opposite ends of the rotation shaft 31 respectively penetrate the first through holes 23 to slide with respect to the first through holes 23.

In another embodiment, the directions indicated by the first direction and the second direction are different from those described in the above embodiment, the first direction is the y direction shown in fig. 2, the second direction is the x direction shown in fig. 2, the first side wall extends along the first direction (the y direction shown in fig. 2), the two first side walls are located at opposite sides of the accommodating cavity in the second direction (the x direction shown in fig. 2), the rotating shaft extends along the second direction (the x direction shown in fig. 2) in the accommodating cavity, the first through hole 23 is disposed on the first side wall, and the first through hole extends along the first direction (the y direction shown in fig. 2). The extending direction of the plane formed by the first direction and the second direction can be used for representing the horizontal direction of the spray head body assembly in the normal use state no matter what direction is represented by the first direction and the second direction under the absolute coordinate.

The x-direction shown in fig. 2 is taken as a first direction, and the y-direction is taken as a second direction. The transmission assembly 4 is arranged outside the at least one first side wall 22, that is to say the transmission assembly 4 may be arranged between the drawer 2 and the body 1, or the transmission assembly 4 may be arranged outside the body 1 remote from the cavity 11. Opposite ends of the transmission assembly 4 in the first direction (x direction shown in fig. 2) are rotatably connected to the end of the rotation shaft 31 and the first side wall 22, respectively.

The positional relationship of the impeller 3, the transmission assembly 4 and the first side wall 22 will be described below in conjunction with the movement of the impeller 3: under the condition that water introduced into the accommodating cavity 21 at the water inlet 12 is impacted to the blades 32, the water can act on the impact force to the blades 32, and the impact force is different on two sides of the rotating shaft, so that torque around the rotating shaft 31 is generated, the blades 32 can drive the rotating shaft 31 to rotate around the axis direction (the y direction shown in fig. 2), and further drive the transmission assembly 4 to rotate and slide, so that the transmission assembly 4 rotates relative to the side wall at the other end, which is rotationally connected with the first side wall, and further drives the transmission assembly 4 to slide, and the transmission assembly 4 drives the impeller to slide. In the above movement process, the part impacted by the water flow provides the kinetic energy for the movement of the impeller 3 and the transmission assembly 4, and the transmission assembly 4 can drive the impeller 3 to resume movement so as to overcome the acting force of the water flow in the fixed direction, thereby realizing the continuous movement of the impeller 3 in the accommodating cavity 21.

It should be noted that the embodiment of the present invention is not limited to the specific structural form of the above-mentioned transmission assembly 4, and the transmission assembly may only use a member similar to a crank and a slider to implement the mutual conversion between rotation and movement according to the motion principle of the crank slider.

In some embodiments, the drawer 2 is detachably connected to the main body 1, and of course, the drawer 2 may also be slidably connected to the main body 1, where the cavity 11 is open at one side in the first direction, and the drawer 2 may enter the cavity 11 from the opening. The embodiment of the present invention is not limited to the specific connection form of the drawer 2 with the main body 1. The relative position relation between the drawer 2 and the cavity 11 can be changed in the process of moving the drawer 2 relative to the main body 1, the relative position relation between the drawer 2 and the cavity 11 can be divided into three states, in the first state, the drawer 2 enters the cavity 11, the drawer 2 seals one end of the opening of the cavity 11, the accommodating cavity 21 in the drawer 2 is sealed by the inner wall surface, close to the cavity 11, of the main body 1, so that the cavity 11 and the accommodating cavity 21 are relatively sealed with the outside, and the cavity 11 and the accommodating cavity 21 can be communicated with the outside only through specially arranged water inlets and water outlets. In the second state, the drawer 2 is moved away from the cavity 11 in a first direction (x direction shown in fig. 2) relative to the cavity 11, so that the opening size of the body 1 to open the accommodating chamber 21 is gradually increased. In the third state, the distance between the drawer 2 and the body 1 in the first direction (x direction shown in fig. 2) reaches a maximum value, or the drawer and the body have no connection relationship in the first direction (x direction shown in fig. 2), the opening of the accommodation chamber 21 in the drawer 2 reaches a maximum value.

According to the embodiment of the invention, the drawer is movably connected with the main body, so that the containing cavity in the drawer can be opened relative to the main body, a user can directly open the drawer without opening the main body, the operation difficulty of the user is reduced, the user can directly supplement treatment substances to the containing cavity in the drawer, and the operation convenience of the user is improved.

In some embodiments, as shown in fig. 3, the drive assembly 4 includes a slider 41, a hinge structure 42, and a connector 43. The slider 41 is disposed outside the first through hole 23, wherein the first through hole 23 has opposite sides in the second direction (the direction perpendicular to the paper surface shown in fig. 3), and one side is a side close to the accommodating cavity, which may be defined as an inner side of the first through hole, and the other side is a side far from the accommodating cavity, which may be defined as an outer side of the first through hole. According to the embodiment of the invention, the sliding block is arranged at the outer side of the first through hole, so that the space for accommodating objects in the accommodating cavity is increased. The sliding block 41 is fixedly connected with the rotating shaft 31, that is, during the rotation of the rotating shaft 31, the sliding block 41 can rotate along with the rotating shaft 31, and the circle center of the rotation of the sliding block 41 is at the position where the rotating shaft is connected with the sliding block, wherein the position of the rotating shaft 31 shown in fig. 3 can be used for indicating the rotation circle center of the sliding block 41.

As shown in fig. 3, the hinge structure 42 is fixedly connected to the outer side of the first sidewall 22 with the first through hole 23, and the first sidewall 22 has two opposite sides in the second direction (the direction perpendicular to the paper surface shown in fig. 3), wherein one side is close to the accommodating cavity 21, and can be regarded as the inner side of the first sidewall 22, and the other side is far from the accommodating cavity 21, and can be regarded as the outer side of the first sidewall 22. The hinge structure 42 is fixed to the side of the first side wall 22 remote from the accommodating chamber 21, that is, the hinge structure 42 and the slider 41 are both located on the same side of the first side wall 22. The hinge structure 42 is disposed at a distance from the first through hole 23 in the first direction (left-right direction shown in fig. 3). It should be noted that, the hinge structure 42 may be located at the same position as the first through hole 23 in a third direction (up-down direction shown in fig. 3), and the third direction may be the up-down direction of the nozzle body assembly in a normal use state. In the case that the hinge structure 42 and the slider 41 are located at the same position in the third direction, the transmission assembly 4 can be regarded as a centering crank slider mechanism; in other embodiments, the hinge structure 42 and the first through hole 23 may not be located at the same position in the third direction (up-down direction shown in fig. 3), and the transmission assembly 4 may be regarded as an offset crank block mechanism. As shown in fig. 3, opposite ends of the connecting piece 43 in the first direction (left-right direction in fig. 3) are hinged with the slider 41 and the hinge structure 42, respectively.

In some embodiments, as shown in fig. 3, the connector 43 is a torsion spring that includes a multi-layer coiled torsion portion 433, a first extension 434 and a second extension 435 that extend from the torsion portion 433 to opposite sides of a first direction (left-right direction shown in fig. 3); wherein the first extension 434 is hinged with the slider 41 and the second extension 435 is hinged with the hinge structure 42. The principle of motion of the transmission is described below with reference to fig. 2: the water flow impacts the blades in the accommodating cavity, the blades drive the rotating shaft 31 to move around the axial direction (the direction perpendicular to the paper surface shown in fig. 3) and move along the extending direction (the left-right direction shown in fig. 3) of the first through hole 23, in the rotating process of the rotating shaft 31, the rotating shaft 31 drives the sliding block 41 to rotate, one end of the first extending part 434 is connected with the sliding block 41 so as to rotate along with the sliding block 41, and the sliding of the rotating shaft 31 in the first direction also drives the sliding block 41 and the first extending part 434 to slide in the first direction, and the first extending part 434 moves along the first direction under the common driving of the two movements. Taking the example that the end of the first extension portion 434 connected to the slider 41 moves leftwards along the first direction, in the above process, the included angle θ between the first extension portion 434 and the second extension portion 435 is increased, the torsion portion 433 can store and release energy, and the torsion portion 433 can drive the end of the first extension portion 434 connected to the slider 41 to move rightwards along the first direction under the action of torque, so that the included angle θ between the first extension portion 434 and the second extension portion 435 is reduced, thereby realizing the reciprocating motion of the slider 41 back and forth in the extending direction of the first through hole 23.

According to the embodiment of the invention, the connecting piece is set as the torsion spring, so that the impeller generates relative motion under the impact of water, and the impeller generates recovery motion under the action of the torsion spring, so that the automatic reciprocating motion of the impeller in the extending direction of the first through hole is realized, other external power sources are not needed, the driving direction is simple, the structural expansibility is stronger, and the cost is low.

In some embodiments, as shown in FIG. 2, the blade 32 is a flexible body, or the surface of the blade 32 is coated with a flexible member. Flexible means that the blade 32 is softer or the wrapping flexible around the outside of the blade 32 is softer rather than a rigid structure. According to the embodiment of the invention, the blades or the surfaces of the blades are flexible, so that the contact area between the blades and substances in the accommodating cavity in the rotation process is increased, the blades can be cleaned to dead angles in the drawer, and the risk of residual substances in the drawer is reduced.
