DETAILED DESCRIPTION

[0039] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] In the description of the embodiments of the present application, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0041] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0042] The embodiment of the present application provides a nozzle unit 100 for a clothes processing device. Figure 1 and Figure 4 The spray head unit 100 includes a shell 10 and a plurality of joint pipes 50. The shell 10 has a cavity and a water spray port that are interconnected. The water spray port can discharge the fluid in the cavity, such as putting the fluid in the cavity into the laundry processing chamber of the laundry processing device.

[0043] The present application also provides a clothes processing device. Figures 7 to 10 The laundry processing device includes a laundry processing chamber (not shown), multiple water inlet pipes 300 and multiple pipe clamps 400, and the nozzle unit 100 of any embodiment of the present application. The laundry processing chamber is used to accommodate the laundry to be processed. The laundry processing device includes but is not limited to a washing machine, a washer-dryer, etc.

[0044] Exemplarily, in one embodiment, the clothing processing device further includes a housing, a barrel assembly and a door seal 200. The barrel assembly and the door seal 200 are both arranged in the housing, and the door seal 200 is located on the front side of the barrel assembly. The connected space formed by the interior of the barrel assembly and the radial inner side of the door seal 200 constitutes a clothing processing chamber.

[0045] See also Figure 2 Multiple joint pipes 50 are connected to the shell 10 and are spaced apart along a first direction R. The joint pipes 50 are used to introduce fluid into the cavity. The joint pipe 50 includes a pipe body 504 and a first stopper 501. The first stopper 501 is disposed on the outer periphery of the end of the pipe body 504 away from the shell 10. The first stopper 501 protrudes from the outer peripheral surface of the pipe body 504. In other words, the maximum outer edge dimension of the first stopper 501 is larger than the outer diameter of the pipe body 504.

[0046] The plurality of joint pipes 50 mentioned above include but are not limited to two, three or more joint pipes 50 .

[0047] The first stopper 501 may be provided to completely surround the circumference of the tube body 504 , or may be provided to partially surround the circumference of the body 504 , which is not limited herein.

[0048] The first stop portions 501 of two adjacent joint pipes 50 are staggered in the extending direction of the joint pipe 50 , that is, the positions of the first stop portions 501 of two adjacent joint pipes 50 along the extending direction of the joint pipe 50 are different.

[0049] It should be noted that the first stopper 501 and the pipe body 504 may be an integral component or a separate component, that is, the first stopper 501 is mounted on the outer peripheral surface of the pipe body 504 .

[0050] See also Figure 10 The multiple water inlet pipes 300 are respectively sleeved on the outer circumference of the corresponding joint pipe 50. The pipe clamp 400 surrounds the outer circumference of the water inlet pipe 300 and locks the water inlet pipe 300 to the pipe body 504. The pipe clamp 400 is located on the side of the first stopper 501 close to the shell 10. The multiple water inlet pipes 300 include but are not limited to two, three, or more water inlet pipes 300.

[0051] It will be appreciated that within the laundry processing apparatus, the first stopper 501 is located within the water inlet pipe 300, and the pipe clamp 400 secures the water inlet pipe 300 to the pipe body 504. The first stopper 501, in conjunction with the pipe clamp 400, limits the water inlet pipe 300, thereby securing the water inlet pipe 300 to the pipe body 504. The staggered arrangement of the first stoppers 501 of two adjacent joint pipes 50 facilitates the staggered placement of the pipe clamps 400 on the two adjacent pipe bodies 504, thereby facilitating installation of the pipe clamps 400 on the corresponding portions of the water inlet pipe 300 on the pipe body 504.

[0052] For example, in one embodiment, the maximum outer edge size of the first stop portion 501 is larger than the inner diameter of the water inlet pipe 300, and the water inlet pipe 300 has a certain elasticity. After the first stop portion 501 is pushed into the water inlet pipe 300, the inner wall of the water inlet pipe 300 undergoes elastic deformation, so that the inner wall of the water inlet pipe 300 fits tightly on the first stop portion 501, thereby enhancing the reliability of the connection and also helping to improve the sealing performance between the water inlet pipe 300 and the connecting pipe 50.

[0053] The form of the pipe clamp 400 is not limited. For example, in one embodiment, the pipe clamp 400 includes a hoop and a lock buckle. The two ends of the hoop are respectively provided with lock buckles. When the lock buckles are fastened, the pipe clamp 400 is circled to lock the water inlet pipe 300 passing through the hoop on the pipe body 504.

[0054] For some examples, see Figure 7 The first stopper 501 is radially protruded from the outer peripheral surface of the pipe body 504 , and the shape of the pipe body 504 is basically cylindrical.

[0055] As the joint pipe 50 extends from the middle region toward both ends, the radial dimension of the first stop portion 501 along the pipe body 504 gradually decreases. In the figure, the dimension d2 of the middle region is obviously larger than the dimension d1 of one of the two ends, and also larger than the dimension d3 of the other two ends.

[0056] That is to say, viewed along the extension direction of the connecting pipe 50, the radial dimension of the first stop portion 501 gradually decreases from the middle part to the two ends. In other words, the outer wall of the first stop portion 501 is composed of at least two conical surfaces, and the conical surfaces can play a guiding role, so that when the first stop portion 501 is pushed into or out of the water inlet pipe 300 along the extension direction of the connecting pipe 50, the movement is more labor-saving and less likely to scratch the inner wall of the water inlet pipe 300.

[0057] For some examples, see Figure 2 and Figure 3 The joint pipe 50 includes a second stopper 502, which is disposed on the outer periphery of the pipe body 504 and radially protrudes from the outer peripheral surface of the pipe body 504. In other words, the maximum outer edge of the second stopper 502 is larger than the outer diameter of the pipe body 504. The second stopper 502 is located on the side of the first stopper 501 facing the shell 10. The portion of the pipe body 504 between the first stopper 501 and the second stopper 502 serves as the mounting area for the pipe clamp 400, which is designed to mate with the pipe clamp 400.

[0058] It can be understood that, in the process of pushing the first stop portion 501 into the water inlet pipe 300, the length of the portion of the water inlet pipe 300 that is sleeved on the joint pipe 50 gradually increases until one end of the water inlet pipe 300 abuts against the side of the second stop portion 502 close to the first stop portion 501. The second stop portion 502 plays a positioning role during the installation process, which facilitates the operator to accurately install the water inlet pipe 300 in the preset position, which is conducive to improving the assembly quality and increasing the assembly speed.

[0059] In some embodiments, the radial dimension of the first stopper 501 along the pipe body 504 is smaller than the radial dimension of the second stopper 502 along the pipe body 504. In this way, the first stopper 501 can be smoothly pushed into the water inlet pipe 300, and the second stopper 502 can more effectively serve as a stopper and positioning function.

[0060] For some examples, see Figure 3 and Figure 11The joint pipe 50 includes a plug-in positioning portion 503 disposed on the outer periphery of the pipe body 504. The plug-in positioning portion 503 radially protrudes from the outer peripheral surface of the pipe body 504, meaning that the maximum outer edge of the plug-in positioning portion 503 is larger than the outer diameter of the pipe body 504. The plug-in positioning portion 503 is located on the side of the second stopper 502 facing the housing 10. The portion of the pipe body 504 between the plug-in positioning portion 503 and the housing 10 forms an insertion zone for insertion into the door seal 200 of the laundry handling device.

[0061] The joint pipe 50 not only transports fluid from the water inlet pipe 300 to the cavity of the housing 10, but also serves to limit the position of the spray head unit 100 when it is installed on the door seal 200. For example, in one embodiment, the door seal 200 is provided with a plurality of mounting holes spaced apart along the circumference. The joint pipe 50 passes through each of the mounting holes until it penetrates the door seal 200 through the insertion area, thereby limiting the spray head unit 100 on the door seal 200 along the circumference of the door seal 200.

[0062] In some embodiments, the radial dimension of the plug-in positioning portion 503 along the tube body 504 is smaller than the radial dimension of the second stop portion 502 along the tube body 504. In this way, the plug-in positioning portion 503 can pass through the mounting hole on the door seal ring 200 more smoothly during the insertion process.

[0063] As an optional embodiment, the order of the radial dimensions of the first stop portion 501, the second stop portion 502 and the plug-in positioning portion 503 along the tube body 504 from large to small is: second stop portion 502, plug-in positioning portion 503, first stop portion 501.

[0064] As an optional embodiment, the radial dimensions of the first stopping portion 501 and the insertion positioning portion 503 along the tube body 504 may be the same.

[0065] For some examples, see Figure 6 The center lines of the plurality of joint pipes 50 along their extending directions are located in the same plane, and the plurality of joint pipes 50 are bent toward the same side from the shell 10 to a direction away from the shell 10 .

[0066] That is, the joint pipes 50 are arranged in parallel and extend in the same direction, which facilitates centralized pipe laying and facilitates the assembly of the water inlet pipe 300 and the nozzle unit 100. The multiple joint pipes 50 are bent to the same side to avoid other structures of the clothes processing device during installation.

[0067] Of course, in other embodiments, the plurality of joint pipes 50 may all be straight pipes without bends, or may be composed of straight pipes connected in multiple directions, with the straight pipes connected at their joints via bent pipes.

[0068] For some examples, see Figure 6 The nozzle unit 100 also includes a first spacing structure 20, which is arranged inside the shell 10 and separates the cavity into at least a first cavity 10A and a second cavity 10B. The first cavity 10A and the second cavity 10B are not connected to each other, that is, the fluid in the first cavity 10A will not flow into the second cavity 10B, and the fluid in the second cavity 10B will not flow into the first cavity 10A.

[0069] The shell 10 has a first water inlet 10a and a second water inlet 10c. The water outlets include a first water outlet 10b and a second water outlet 10d. The first chamber 10A connects the first water inlet 10a and the first water outlet 10b, while the second chamber 10B connects the second water inlet 10c and the second water outlet 10d. The first water inlet 10a and the second water inlet 10c are connected to corresponding joint pipes 50.

[0070] The laundry processing device further includes a first water channel 300A and a second water channel 300B. The first water channel 300A connects the water source and the first water inlet 10a and flows through one of the joint pipes 50. The second water channel 300B connects the water source and the second water inlet 10c and flows through the other joint pipe 50.

[0071] In this embodiment, since the first cavity 10A and the second cavity 10B are not connected to each other, the first water inlet 10a and the second water inlet 10c can be connected to water channels with different functional purposes in the clothing processing equipment, so that the nozzle unit 100 can release fluids with different functions into the clothing processing cavity, which is beneficial to improving the integration of the nozzle unit 100.

[0072] Exemplarily, the first and second water spray ports 10b, 10d are used to deliver fluid to the laundry processing chamber. The fluid in the first water channel 300A is a detergent mixed solution, which flows out through the first water spray port 10b, while the fluid in the second water channel 300B is clean water, which flows out through the second water spray port 10d. The first and second water channels 300A, 300B (and the third water channel 300C mentioned later) refer to the fluid flow paths of the fluids and are not limited to specific pipe structures. In this embodiment, the nozzle unit 100 serves to deliver detergent ingredients and assist in water inflow.

[0073] The detergent mixed solution mentioned in this specification is only for the convenience of description and refers to a mixed solution in which detergent is dissolved. Its mass percentage concentration is not limited, and it does not limit the detergent to be completely dissolved.

[0074] The water source referred to in this specification can be the water supply device of the laundry processing apparatus, such as a water inlet valve, or the outlet of a circulation pump that pumps water from the drum assembly into the first water path 300A or the second water path 300B. Clean water is not limited to tap water; it refers to a fluid with a lower concentration of detergent components than a detergent mixture.

[0075] For example, in one embodiment, the laundry processing apparatus further includes a detergent supply assembly, which includes a detergent box and a dispenser box. The dispenser box is retractably disposed within the detergent box and is used to hold detergent required for washing clothes, such as laundry liquid and softener. First water channel 300A flows through the detergent supply assembly to form a mixed detergent solution.

[0076] Exemplarily, in one embodiment, the clothing processing device further includes a water inlet valve, which is connected to an external water supply device, such as a tap water pipe, to deliver clean water to the water inlet valve. The water inlet end of the second water path 300B is connected to the water inlet valve to deliver clean water to the second chamber 10B through the second water inlet 10c.

[0077] For example, in one embodiment, the laundry processing device further includes a door assembly and a door glass bowl, with the door glass bowl being mounted on the door assembly. The front of the cabinet has a clothing inlet through which the user can place laundry into the laundry processing chamber. The door glass bowl serves to allow the user to observe the interior of the laundry processing chamber and to fill a portion of the radially inner side of the door seal 200 to prevent laundry from falling into the chamber. The door assembly is rotatably mounted on the cabinet to open and close the clothing inlet.

[0078] For example, in one embodiment, the nozzle unit 100 is arranged on the door sealing ring 200, the first water spray port 10b sprays water toward the clothing processing chamber, and the second water spray port 10d sprays water toward the door glass bowl and / or the door sealing ring 200. The first water spray port 10b sprays the detergent mixed solution on the clothes to be treated, which is beneficial for the contact between the detergent components and the surface of the clothes, thereby improving the cleaning effect. Since the door glass bowl does not rotate with the rotation of the barrel assembly, foam and other substances are easily accumulated during the washing process. The second water spray port 10d sprays clean water on the door glass bowl and / or the door sealing ring 200, which is beneficial for keeping the door sealing ring 200 and the door glass bowl clean. On the one hand, the user can observe the internal situation through the door glass bowl, and on the other hand, after the clothes are washed, the residual detergent components are reduced, thereby inhibiting the growth of microorganisms. In this embodiment, the nozzle unit 100 plays the role of adding detergent components and spraying cleaning.

[0079] For some examples, see Figure 6 The number of first water inlets 10a is at least two, and the multiple joint pipes 50 include a first joint pipe 51, a second joint pipe 52 and a third joint pipe 53. The first joint pipe 51 and the second joint pipe 52 are respectively connected to the first water inlet 10a, and the third joint pipe 53 is connected to the second water inlet 10c.

[0080] The clothing processing device also includes a third water channel 300C, which connects the water source to one of the first water inlets 10a and flows through one of the first connector pipe 51 and the second connector pipe 52, the other of which is located on the flow path of the first water channel 300A. The fluid in the third water channel 300C is clean water. The first water channel 300A transports the detergent mixed solution into the first chamber 10A, where it mixes with the clean water transported by the third water channel 300C. The intersection of the two fluids with different components promotes the dissolution and mixing of the detergent. The first water outlet 10b releases the mixture of the detergent mixed solution and clean water into the clothing processing chamber, which facilitates full contact between the detergent and the clothing to be treated, thereby improving the cleaning effect.

[0081] In some embodiments, the first joint tube 51 is the shortest among the first, second, and third joint tubes 51, 52, 53, and is positioned between the second and third joint tubes 52, 53. In other words, the first stopper 501 of the second joint tube 52 is closest to the housing 10. This allows for sufficient space between the first and second joint tubes 51, 52, and between the second and third joint tubes 52, 53 during installation of the tube clamp 400, allowing the tube clamps 400 to be staggered, facilitating installation.

[0082] In some embodiments, the housing 10 includes a top wall 14 and a bottom wall 15, which are arranged along a second direction D, with the first direction R and the second direction D being perpendicular. The housing 10 also includes a first side wall 12, a second side wall 13, and an end plate 11, which are spaced apart from each other along a third direction A. In this embodiment, the top wall 14, the bottom wall 15, the first side wall 12, the second side wall 13, and the two end plates 11 are connected together to form a box-shaped housing 10.

[0083] In some embodiments, the first joint pipe 51 , the second joint pipe 52 , and the third joint pipe 53 are all connected to the top wall 14 , so as to facilitate centralized pipe arrangement on the same side of the shell 10 .

[0084] For some examples, see Figure 6 The space between the first spacing structure 20 and one of the end plates 11 forms a second cavity 10B. That is, the second cavity 10B is located at one end of the shell 10 along the first direction R. There are at least two second water spraying ports 10d, and their locations and corresponding water spraying directions are not limited.

[0085] Exemplarily, the at least two second water spray outlets 10d mentioned above include a first water spray outlet 10d1, which is arranged at a position of the bottom wall 15 corresponding to the second cavity 10B. In this way, when the nozzle assembly is installed in place, it is conducive to spraying water to the door glass bowl.

[0086] Exemplarily, the at least two second water spray outlets 10d mentioned above include a second water spray sub-outlet 10d2, which is arranged at a position of the end plate 11 corresponding to the second cavity 10B. In this way, when the nozzle assembly is installed in place, it is beneficial to spray water onto the door seal 200, thereby cleaning the door seal 200 and reducing the chance of microbial growth.

[0087] Exemplarily, a portion of the bottom wall 15 corresponding to the second cavity 10B and a portion of the end plate 11 corresponding to the second cavity 10B are respectively provided with a second water spraying port 10d to expand the spraying range and improve the effect.

[0088] In some embodiments, the cross-sectional area of ​​the second water spray outlet 10d2 provided on the end plate 11 is greater than the cross-sectional area of ​​the first water spray outlet 10d1 provided on the bottom wall 15. In other words, the fluid in the second chamber 10B is primarily discharged through the second water spray outlet 10d2 provided on the end plate 11, thereby improving the cleaning effect on the door seal 200.

[0089] For some examples, see Figure 2 and Figure 3 The two end plates 11 extend in an inclined direction toward each other along the direction from the top wall 14 to the bottom wall 15. This not only reduces the space occupied by the shell 10 along the first direction R, but also facilitates adjustment of the water spray angle of the first water spray sub-port 10d1 provided on the end plate 11.

[0090] With respect to the second direction D, the inclination angles of the two end plate portions 11 may be the same or different.

[0091] In some embodiments, the first water outlet 10b is disposed on the first sidewall 12, and the third direction A intersects the plane containing the first direction R and the second direction D. In this embodiment, the first water outlet 10b is disposed on the first sidewall 12, and the first water inlet 10a is disposed on the top wall 14. The axial direction of the first water outlet 10b is different from the axial direction of the first water inlet 10a. Fluid enters the first cavity 10A through the first water inlet 10a, changing its flow direction to fill the entire first cavity 10A as much as possible. Fluid ejected from the outlet of the nozzle 40 can be mixed more thoroughly with the fluid in the first cavity 10A.

[0092] In some embodiments, the first side wall 12 extends obliquely toward the second side wall 13 along the direction from the top wall 14 to the bottom wall 15. In this way, when the spray head unit 100 is installed in place, it is beneficial to spray water toward the door glass bowl.

[0093] For some examples, see Figure 4From the top wall 14 to the bottom wall 15, the first side wall 12 and the second side wall 13 extend obliquely toward each other. In other words, the cross-sections of the first chamber 10A and the second chamber 10B gradually decrease in size from the top wall 14 to the bottom wall 15. This allows for a higher water pressure on the side of the first chamber 10A near the bottom wall 15, while a higher water pressure on the side of the second chamber 10B near the bottom wall 15 is achieved, resulting in a higher flow rate for the fluid discharged from the first and second water outlets 10b, 10d.

[0094] For example, see Figure 8 and Figure 9 In the laundry processing apparatus, the first direction R is along the circumference of the door seal 200, the second direction D is along the radial direction of the door seal 200, and the third direction A is approximately along the axial direction of the laundry processing chamber. The first sidewall 12 faces the rear side of the laundry processing apparatus. The second sidewall 13 faces the front side of the laundry processing apparatus.

[0095] The first water spray port 10b sprays water toward the rear lower side of the clothing processing device, and the end plate portion 11 provided with the first water spray sub-port 10d1 faces the right side of the clothing processing device and is inclined downward so that the first water spray sub-port 10d1 sprays water roughly along the circumference of the door sealing ring 200.

[0096] For some examples, see Figure 1 and Figure 4 The nozzle unit 100 further includes a nozzle 40 disposed in the first cavity 10A. The nozzle 40 is connected to one end of the first joint pipe 51 or the second joint pipe 52. The outlet of the nozzle 40 sprays water toward the first water spray port 10b.

[0097] In this way, on the one hand, the fluid ejected from the outlet of the nozzle 40 will not be completely sprayed onto the inner wall of the first cavity 10A, but will be discharged through the first water outlet 10b while retaining the posture when ejected, thereby driving the fluid discharged from the first water outlet 10b to be ejected; on the other hand, the nozzle 40 is arranged to protrude from the inner wall of the first cavity 10A, and when its outlet ejects fluid, it has a suction effect on the fluid near the outlet, thereby improving the mixing and foaming effects.

[0098] See also Figure 1 For example, the flow cross section of the first water jet port 10b is larger than the flow cross section of the outlet of the nozzle 40. The flow cross section mentioned in this specification refers to the cross section perpendicular to the flow direction of the fluid in the fluid flow channel.

[0099] Exemplarily, the nozzle 40 is connected to the first water inlet 10a through which the third water channel 300C flows. The third water channel 300C flows through the nozzle 40, that is, the fluid sprayed out from the outlet of the nozzle 40 is clean water, which mixes with the detergent mixed solution in the first cavity 10A.

[0100] For some examples, see Figure 6 The nozzle 40 includes a reducing tube 41 connected to the first water inlet 10a. This reducing tube 41 is used to increase the flow rate of the fluid discharged from the nozzle 40 outlet. It will be appreciated that the flow cross-section of the reducing tube 41 gradually decreases along the flow direction of the fluid, thereby increasing the flow rate. A higher flow rate of the fluid discharged from the nozzle 40 outlet more significantly impacts the detergent mixture in the first chamber 10A, further promoting detergent mixing and foaming.

[0101] For example, in one embodiment, the nozzle 40 is connected to one end of the second joint pipe 52. The nozzle unit 100 further includes a turbulence structure 80 disposed in the second joint pipe 52 for providing a circumferential velocity component to the fluid in the second joint pipe 52. The provision of the circumferential velocity component means that the velocity component of the fluid in the second joint pipe 52, after passing through the turbulence structure 80, in the circumferential direction of the second joint pipe 52 is non-zero. The circumferential direction of the second joint pipe 52 is perpendicular to the extension direction of the second joint pipe 52.

[0102] In this embodiment, the turbulent structure 80 allows part of the fluid to have both a circumferential movement speed and a forward flow speed, so that part of the fluid roughly moves in a spiral. When the fluid is ejected from the water outlet end of the second joint pipe 52, the fluid is facilitated to diffuse in a conical shape, with a wider radiation range and better visual effect.

[0103] Exemplarily, the turbulence structure 80 includes one or more spiral blades, which divide at least a portion of the length of the second connector pipe 52 into multiple sub-flow channels. The term "multiple" refers to a plurality of blades, which can be two, three, or more. This means that the number of helical turns is not less than two, and does not limit the number of turns. After the fluid passes through the spiral blades, it exhibits a spiral motion. The spiral blades have a simple structure, provide a good flow disturbance effect on the fluid, and provide low resistance, thereby reducing energy loss during passage.

[0104] In some embodiments, the spray head unit 100 further includes a second partitioning structure 30 disposed within the housing 10. The second partitioning structure 30 separates the cavity into a closed chamber 10E. The first chamber 10A, the second chamber 10B, and the closed chamber 10E are not interconnected. The closed chamber 10E is a closed chamber that is not connected to the outside.

[0105] It should be noted that the nozzle unit 100 is arranged in the clothing processing chamber and has certain shape characteristics based on factors such as the installation space in the clothing processing equipment or aesthetic considerations. The setting of the closed chamber 10E can separate the unused space in the nozzle unit 100 to adjust the size of the first chamber 10A and the second chamber 10B, which not only meets the design requirements of the first chamber 10A and the second chamber 10B, but also takes into account the installation space or aesthetic considerations.

[0106] The second spacing structure 30 may be in any form, such as a plate, a cylinder, etc. The first spacing structure 20 and the second spacing structure 30 may be in the same or different form.

[0107] For some examples, see Figure 6 The first cavity 10A and the closed cavity 10E are located on opposite sides of the second spacing structure 30. In other words, the first cavity 10A and the closed cavity 10E are adjacent to each other, and the surfaces on the opposite sides of the second spacing structure 30 respectively constitute a portion of the inner wall of the first cavity 10A and a portion of the inner wall of the closed cavity 10E.

[0108] In some embodiments, when the nozzle unit 100 is installed in place, the position of the closed cavity 10E is lower than that of the first cavity 10A. Under the influence of gravity, the fluid in the first cavity 10A tends to flow toward the second spacing structure 30. Therefore, the closed cavity 10E is conducive to reducing the amount of fluid residue in the first cavity 10A, and the second spacing structure 30 is also conducive to diverting the fluid in the first cavity 10A to the first water outlet 10b.

[0109] Exemplarily, the fluid in the first cavity 10A is a detergent mixed solution, and reducing its residue in the first cavity 10A is beneficial to keeping the nozzle unit 100 clean and inhibiting the growth of microorganisms caused by some formulas in the detergent ingredients.

[0110] For some examples, see Figure 2 、 Figure 3 and Figure 6 The first cavity 10A, the second cavity 10B, and the closed cavity 10E are arranged along the first direction R. Specifically, the shell 10 extends along the first direction R.

[0111] The two end plates 11 are spaced apart from each other along the first direction R. The end plates 11 serve as the external appearance structure of the showerhead unit 100 .

[0112] The space between the second spacing structure 30 and one of the end plates 11 forms a closed cavity 10E. The shell 10 has a relatively simple structure, making it easy to manufacture and install. The linear arrangement of the first and second water outlets 10b, 10d facilitates the arrangement of the first and second water outlets, preventing them from interfering with each other when discharging fluid.

[0113] Of course, in other embodiments, the first cavity 10A, the second cavity 10B and the closed cavity 10E may be circumferentially distributed or nested, for example, the first spacing structure 20 is cylindrically arranged in the first cavity 10A to separate the second cavity 10B.

[0114] As an optional embodiment, the top wall 14 and the first joint pipe 51, the second joint pipe 52, and the third joint pipe 53 are an integrated structure, the two end plate portions 11, the first side wall 12, the second side wall 13, the bottom wall 15, the first partition structure 20, and the second partition structure 30 are an integrated structure, and the mouth 40 is assembled on the top wall 14 as an independent part and is connected to the first water inlet 10a.

[0115] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
