"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0055] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example that is included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0056] This application provides a garment processing device. Referring to Figures 9 and 10, the garment processing device includes a housing, a drum assembly, a door seal ring 200, a nozzle unit 100, and at least one water channel. The garment processing device can take the form of, but is not limited to, washing machines and washer-dryer combos.

[0057] The cabinet has a clothing loading port, and the cylinder assembly is located inside the cabinet. The door seal ring 200 is located on the front side of the cylinder assembly. The communicating space formed by the interior of the cylinder assembly and the radially inner side of the door seal ring 200 constitutes the clothing processing chamber. Users can put clothes into the clothing processing chamber through the clothing loading port of the cabinet.

[0058] In one embodiment, the garment handling device includes a door assembly disposed on a housing for opening and closing the garment inlet. Exemplarily, the door assembly includes a door glass bowl that arches toward the garment handling chamber, extending radially inward toward the door seal ring. The door glass bowl serves to allow a user to observe the interior of the garment handling chamber and to fill a portion of the radially inward area of ​​the door seal ring 200 to reduce garment falling into it.

[0059] Referring to Figures 8 and 1, the nozzle unit 100 is disposed on the door seal ring 200. The nozzle unit 100 includes a housing 10, which has at least one cavity, at least one water inlet, and at least one spray nozzle. That is, the number of cavities can be one, two, three, or more, the number of water inlets can be one, two, three, or more, and the number of spray nozzles can be one, two, three, or more. The cavity connects the corresponding water inlet and spray nozzle, that is, each water inlet is connected to the spray nozzle on the cavity through the cavity it is located in.

[0060] For example, at least one water path connects a water source and at least one water inlet. It should be noted that the water path (and the first water path 300A, the second water path 300B, and the third water path 300C mentioned below) refers to the fluid flow path and is not limited to a specific pipe structure. The fluid in the water path enters the corresponding cavity through the water inlet it is connected to, while the spray nozzle is used to discharge the fluid in the corresponding cavity, which finally enters the clothing processing chamber.

[0061] The housing 10 includes a first sidewall 13 facing the clothing inlet, i.e., the front side of the clothing handling device. It is understood that the surface of the first sidewall 13 facing the clothing inlet is the exterior surface of the nozzle unit 100 and is easily visible to the user. The surface of the first sidewall 13 facing the clothing inlet is a continuous surface, and the water inlet and spray nozzle are located in the remaining parts of the housing 10 excluding the first sidewall 13.

[0062] The aforementioned continuous surface refers to the surface of the first sidewall 13 facing the clothing inlet being a complete planar structure, without grooves, openings, or other structures processed to remove material, nor any structure protruding from the surrounding surface. The surface of the first sidewall 13 facing the clothing inlet can be curved or flat. Thus, in the clothing handling device provided in this embodiment, the water inlet and spray nozzle on the nozzle unit 100 are not easily observed by the user, while the surface of the continuous first sidewall 13 is more easily seen, resulting in a more aesthetically pleasing appearance for the nozzle unit 100 and improving the user experience.

[0063] In one embodiment, for example, at least one of the water paths mentioned above includes a first water path 300A, wherein the fluid is a detergent mixture solution, which is dispensed into the garment processing chamber through the nozzle unit 100 and comes into contact with the garment to be processed. The detergent mixture solution mentioned in this specification is merely for ease of description and refers to a mixture solution containing dissolved detergent; its mass percentage concentration is not limited, nor is it limited to the complete dissolution of detergent.

[0064] In some embodiments, the housing 10 is located radially inside the door seal ring 200, and when the clothing inlet is opened, the housing 10 is exposed to the external view of the clothing handling equipment through the clothing inlet. The user can directly observe the surface of the first sidewall, while structures such as the water inlet and spray nozzle are difficult to see, thereby improving the aesthetics of the clothing handling equipment.

[0065] In some embodiments, when the clothing inlet is closed, the shell 10 is exposed to the external view of the clothing processing equipment through the door glass bowl. In this way, regardless of whether the user opens the door assembly, the water inlet, spray nozzle and other structures are well hidden, and the overall aesthetics of the clothing processing equipment are hardly affected.

[0066] In some embodiments, referring to Figures 3 and 8, the projection range of the first sidewall 13 defines the projection range of the shell portion 10 in orthographic projection onto a plane perpendicular to the axis of the tube assembly. That is, along the front-rear direction of the garment handling device, the first sidewall 13 can cover the rest of the shell portion 10, making it difficult for it to appear in the user's field of vision, and thus making it difficult for the user to observe the water inlet and spray nozzle located in the rest of the shell portion 10.

[0067] In one embodiment, as exemplified by FIG2, the housing 10 further includes a second sidewall 12, which and the first sidewall 13 are arranged along the front-rear direction of the garment handling device. The second sidewall 12 is located on the side of the first sidewall 13 away from the garment inlet.

[0068] In one embodiment, as exemplified by FIG5, the housing portion 10 further includes two end plate portions 11, which are arranged circumferentially around the door seal ring 200 at opposite ends of the housing portion 10.

[0069] In one embodiment, referring to Figures 5 and 6, the housing 10 further includes a top wall 14 and a bottom wall 15, which are radially spaced along the door seal ring 200. The bottom wall 15 is located on the side of the top wall 14 near the center of the door seal ring 200.

[0070] As an optional embodiment, the housing 10 of the nozzle unit 100 is box-shaped, consisting of a first sidewall 13, a second sidewall 12, a top wall 14, a bottom wall 15, and two end plate portions 11.

[0071] In some embodiments, the end plate portion 11 is flat, and the plane containing the end plate portion 11 is parallel to the axis of the bobbin assembly. That is, the surface structure of the end plate is difficult for the user to see along the front-back direction of the garment processing equipment.

[0072] In some embodiments, referring to Figures 1 and 9, the at least one spray nozzle mentioned above includes a first spray nozzle 10b, which is disposed on a second sidewall 12 for spraying water toward the inside of the drum assembly. The second sidewall 12 is located behind the first side, which facilitates the first spray nozzle 10b spraying water rearward. Exemplarily, in one embodiment, the first spray nozzle 10b sprays a detergent mixture solution onto the clothes to be treated inside the clothes treatment chamber.

[0073] In some embodiments, the second sidewall 12 extends obliquely toward the first sidewall 13 in the direction from the radially outer side to the radially inner side of the door seal ring 200, thereby facilitating the first spray nozzle 10b to spray water obliquely downward toward the rear of the cylinder assembly.

[0074] In some embodiments, the nozzle unit 100 further includes a guide portion 60 disposed on the second sidewall 12 and extending in a direction away from the housing 10. The guide portion 60 has a flow channel 60a communicating with the first nozzle 10b. Fluid ejected from the first nozzle 10b can be discharged outside the nozzle unit 100 through the flow channel 60a. The guide portion 60 guides the fluid passing through it, so that the fluid hardly flows on the outer wall of the housing 10, but is instead concentrated and delivered into the cylinder assembly.

[0075] For example, in one embodiment, the fluid sprayed from the first nozzle 10b is a detergent mixture solution. The detergent components cause it to carry more foam. When the fluid is sprayed through the first nozzle 10b, the lighter foam can also move along the extension direction of the guide channel 60a, thereby reducing the accumulation of foam on the outer wall of the shell 10.

[0076] In some embodiments, please refer to Figure 2. Along the flow direction of the fluid, the cross-sectional area of ​​the flow guide channel 60a gradually increases. Thus, when the fluid flies through the internal space of the flow guide channel 60a, the inner wall of the flow guide channel 60a hardly affects the water outlet pattern of the fluid, so that the fluid ejected from the first nozzle 10b can maintain its original motion state and enter the cylinder assembly.

[0077] In some embodiments, the first sidewall 13 and the second sidewall 12 extend obliquely toward each other in the radial direction toward the inside of the door seal ring 200. That is, in the direction from the radially outer side to the radially inner side of the door seal ring 200, the cross-sections of the first cavity 10A and the second cavity 10B gradually decrease, so that the water pressure of the fluid on the side of the cavity near the bottom wall 15 is greater, thereby resulting in a greater fluid velocity discharged from the first nozzle 10b.

[0078] In some embodiments, referring to Figures 5 and 9, at least one of the above-mentioned spray nozzles includes a spray nozzle 10e, and at least one end plate portion 11 is provided with a spray nozzle 10e for spraying water toward the door seal ring 200. The end plate portion 11 is located at both ends of the housing portion 10 along the circumference of the door seal ring 200, which facilitates the spray nozzle 10e disposed thereon to spray water toward the inside of the door seal ring 200. Exemplarily, the fluid sprayed from the spray nozzle 10e is clean water, which can clean the door seal ring 200, so that there is less detergent residue after the operation of the garment processing equipment is completed, thereby reducing the growth of microorganisms.

[0079] In some embodiments, the bottom wall 15 is provided with a water spray nozzle for spraying water toward the door glass bowl. The fluid discharged from the water spray nozzle on the bottom wall 15 can move downwards onto the door glass bowl. For example, the fluid sprayed from the water spray nozzle on the bottom wall 15 is clean water, which can clean the door glass bowl and allow the user to see the inside of the clothing processing chamber through the door glass bowl.

[0080] In some embodiments, the top wall 14 is provided with a water inlet. Compared to the rest of the housing 10, the top wall 14 is closer to the outside of the door seal ring 200, and the water inlet on the top wall 14 is beneficial for pipe laying.

[0081] In one embodiment, for example, the garment handling equipment further includes a detergent supply component, which includes a detergent dispenser and a dispenser box. The dispenser box is removably disposed within the detergent dispenser and is used to hold detergents required for washing clothes, such as laundry liquid or fabric softener. The first water path 300A flows through the detergent supply component to form a detergent mixture solution, which is then transported to the housing 10 through a pipe connected to the water inlet.

[0082] In some embodiments, referring to Figure 7, the at least one cavity mentioned above includes a first cavity 10A and a second cavity 10B that are not interconnected, meaning that fluid in the first cavity 10A will not enter the second cavity 10B, and fluid in the second cavity 10B will not enter the first cavity 10A. At least one water inlet includes a first water inlet 10a and a second water inlet 10c, and at least one water nozzle includes a first water nozzle 10b and a second water nozzle 10d.

[0083] For example, referring to FIG7, the shell portion 10 includes a first spacer structure 20, which is disposed inside the shell portion 10 and divides the space inside the shell portion 10 into at least a first cavity 10A and a second cavity 10B.

[0084] At least one water path includes a first water path 300A and a second water path 300B. The first water path 300A connects to a water source and a first inlet 10a, and the second water path 300B connects to a water source and a second inlet 10c. The first chamber 10A connects to the first inlet 10a and a first spray nozzle 10b, and the second chamber 10B connects to the second inlet 10c and a second spray nozzle 10d. That is, the first water path 300A supplies fluid to the first chamber 10A through the first inlet 10a, and the fluid in the first chamber 10A is sprayed out through the first spray nozzle 10b; the second water path 300B supplies fluid to the first chamber 10A through the second inlet 10c, and the fluid in the second chamber 10B is sprayed out through the second spray nozzle 10d. 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 circuits with different functions in the clothing processing equipment, so that the nozzle unit 100 can inject fluids with different functions into the clothing processing cavity, which is beneficial to improving the integration of the nozzle unit 100.

[0085] For example, if the fluid in the second water channel 300B is clean water, then the fluid sprayed from the second spray nozzle 10d can also be clean water. As an optional embodiment, the second spray nozzle 10d includes a spray port 10e.

[0086] The water source mentioned in this manual can be the water supply device of the laundry processing equipment, such as the inlet valve, or the outlet of the circulation pump, which can pump water from the drum assembly into the first water channel 300A or the second water channel 300B. Clean water is not limited to tap water, but refers to a fluid with a lower concentration of detergent components compared to the detergent mixture solution.

[0087] For example, in one embodiment, the second spray nozzle 10d is disposed on the bottom wall 15 at the location corresponding to the second cavity 10B, so that when the nozzle assembly is installed in place, it is beneficial to spray water onto the glass bowl of the door.

[0088] For example, in one embodiment, the second spray nozzle 10d includes a spray nozzle 10e, which is disposed on the end plate portion 11 corresponding to the second cavity 10B. Thus, when the nozzle assembly is installed in place, it is beneficial to spray water onto the door seal ring 200.

[0089] For example, in one embodiment, the bottom wall 15 corresponding to the second cavity 10B and the end plate portion 11 corresponding to the second cavity 10B are respectively provided with second water nozzles 10d, which can expand the spraying range and improve the effect.

[0090] In some embodiments, at least one of the aforementioned water paths further includes a third water path 300C, in which the fluid is clean water. The number of first spray nozzles 10b is at least two. The first water path 300A connects to a water source and one of the first inlets 10a, and the third water path 300C connects to the water source and the other first inlet 10a. It is understood that the fluids of the first water path 300A and the third water path 300C mix in the first chamber 10A. The convergence of these two fluids with different compositions can promote the dissolution and mixing of the detergent. The first spray nozzles 10b are used to dispense the mixture of detergent and clean water into the drum assembly, which facilitates full contact between the detergent and the clothes to be treated, improving the cleaning effect.

[0091] In one embodiment, as exemplified by Figure 5, the nozzle unit 100 further includes a nozzle 40 disposed within the first cavity 10A. The nozzle 40 is connected to one of the first water inlets 10a, and the outlet of the nozzle 40 sprays water toward the first water nozzle 10b. Thus, on the one hand, the fluid ejected from the outlet of the nozzle 40 is not completely sprayed onto the inner wall of the first cavity 10A, but retains its ejected posture and is discharged through the first water nozzle 10b, thereby driving the fluid discharged by the first water spray. On the other hand, the nozzle 40 protrudes from the inner wall of the first cavity 10A, and when it ejects fluid from its outlet, it has a suction effect on the fluid near the outlet, improving the mixing and foaming effect.

[0092] As an optional embodiment, the nozzle 40 is connected to the inlet through which the second water passage 300B flows. The fluid in the second water passage 300B is clean water, and the fluid velocity at the outlet of the nozzle 40 is relatively high, resulting in a more pronounced impact effect. The following description will also use the example of the nozzle 40 being connected to the inlet through which the second water passage 300B flows, and the fluid in the second water passage 300B being clean water.

[0093] In some embodiments, referring to Figure 7, the nozzle 40 includes a reducing pipe 41 connected to a first inlet 10a. The reducing pipe 41 is used to increase the flow velocity of the fluid discharged from the outlet of the nozzle 40. It is understood that the cross-sectional area of ​​the reducing pipe 41 gradually decreases along the flow direction of the fluid, thereby increasing the flow velocity. When the flow velocity of the fluid discharged from the outlet of the nozzle 40 is higher, the impact on the detergent mixture solution in the first chamber 10A will be more pronounced, further promoting the mixing and foaming effect of the detergent.

[0094] In some embodiments, referring to FIG7, the nozzle unit 100 further includes a second partition structure 30 disposed within the housing 10. The second partition structure 30 divides the space within the housing 10 into a closed cavity 10E. The first cavity 10A, the second cavity 10B, and the closed cavity 10E are not in communication with each other. The closed cavity 10E is a closed chamber that is not in communication with the outside.

[0095] It should be noted that the nozzle unit 100 is installed inside the garment processing equipment. Depending on the installation space inside the garment processing equipment or for aesthetic considerations, it has certain shape characteristics. The enclosed cavity 10E can separate the unused space inside the nozzle unit 100 to adjust the size of the first cavity 10A and the second cavity 10B, which satisfies the design requirements of the first cavity 10A and the second cavity 10B, while also taking into account the considerations of installation space or aesthetics.

[0096] The form of the second spacer structure 30 is not limited; it can be plate-shaped, cylindrical, etc. The forms of the first spacer structure 20 and the second spacer structure 30 can be the same or different.

[0097] In some embodiments, referring to FIG7, the first cavity 10A and the closed cavity 10E are located on opposite sides of the second spacer structure 30. That is, the first cavity 10A and the closed cavity 10E are arranged adjacent to each other, and the surfaces on opposite sides of the second spacer structure 30 respectively form part of the inner wall of the first cavity 10A and part of the inner wall of the closed cavity 10E.

[0098] In some embodiments, after the nozzle unit 100 is installed, 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 towards the second spacer structure 30. Therefore, the closed cavity 10E is beneficial to reduce the amount of fluid remaining in the first cavity 10A, and the second spacer structure 30 is also beneficial to guide the fluid in the first cavity 10A to the first nozzle 10b.

[0099] In some embodiments, referring to Figures 1, 5, and 7, the nozzle unit 100 includes at least one connector tube 50 connected to the housing 10. The number of connector tubes 50 can be one, two, three, or more. Fluid in the water path enters the corresponding cavity through the connector tube 50 to which it is connected, and the spray nozzle is used to discharge the fluid in the corresponding cavity, which ultimately enters the garment processing chamber.

[0100] The housing 10 is located radially inside the door seal ring 200, and the connector tube 50 passes radially through the door seal ring 200. The housing 10 includes a top wall 14 that extends circumferentially along the door seal ring 200 and overlaps with the radially inner circumferential surface of the door seal ring 200. That is, the top wall 14 is generally arc-shaped, and the shape of the top wall 14 matches the shape of the inner surface of the door seal ring 200. The aforementioned overlap with the radially inner circumferential surface of the door seal ring 200 means that the surface of the top wall 14 abuts against the radially inner circumferential surface of the door seal ring 200, and the shapes of the two are matched so that they fit together as closely as possible. For example, each connector tube 50 is disposed on the top wall 14.

[0101] In other words, in the garment processing device of this application embodiment, the nozzle unit 100 passes through the connector tube 50 from the radially inner side to the radially outer side of the door seal ring 200. The top wall 14 stops on the radially inner side of the door seal ring 200 to limit the nozzle unit 100 on the door seal ring 200. The surface of the top wall 14 is as close as possible to the radially inner circumferential surface of the door seal ring 200, which can minimize the installation space occupied by the nozzle unit 100, avoid interference with the other structures of the door seal ring 200 as much as possible, and also reduce the gap between the nozzle unit 100 and the door seal ring 200 to reduce dirt retention.

[0102] Specifically, the door seal ring 200 has at least one mounting hole, through which the connector tube 50 passes to limit the nozzle unit 100 circumferentially along the door seal ring 200. For example, the number of mounting holes is the same as the number of connector tubes 50, and they correspond one-to-one, with each connector tube 50 passing through a corresponding mounting hole. When there are at least two connector tubes 50, the cooperation of multiple connector tubes 50 and the mounting holes can restrict the rotation of the nozzle unit 100 relative to the door seal ring 200.

[0103] In some embodiments, please refer to FIG7, the nozzle unit 100 is disposed at the upper left part of the door seal ring 200. The nozzle unit 100 may also be disposed at the upper right part of the door seal ring 200. Therefore, the nozzle unit 100 is disposed at an angle relative to the horizontal plane. Under the influence of gravity, the fluid in the first chamber 10A tends to flow downward at an angle.

[0104] The aforementioned upper left portion refers to the area located on the left side of the door seal ring 200, and whose height position is not lower than the center of the door seal ring 200. The aforementioned upper right portion refers to the area located on the right side of the door seal ring 200, and whose height position is not lower than the center of the door seal ring 200.

[0105] In one embodiment, for example, the garment processing apparatus includes a drying tunnel assembly. A detergent supply assembly is disposed at the upper left or upper right portion of the garment processing apparatus and above the door seal ring 200, for supplying a detergent mixture solution to the spray head unit 100 via a first water passage 300A. The drying tunnel body is also disposed above the door seal ring 200 and at the top of the garment processing apparatus, for allowing gas to flow within the drum assembly through an air inlet on the door seal ring 200 to dry the garments. The placement of the spray head unit 100 at the upper left or upper right portion of the door seal ring 200 facilitates the installation of the fabric hose and avoids obstruction of the drying tunnel assembly.

[0106] In some embodiments, there are multiple connector pipes 50, including a first connector pipe 51, a second connector pipe 52 and a third connector pipe 53, with the third connector pipe 53 connected to the second water inlet 10c.

[0107] Multiple connector pipes 50 are arranged at intervals around the door seal ring 200 on the top wall 14, and the center lines of each connector pipe 50 along its extension direction are located on the same plane. That is to say, the first connector pipe 51, the second connector pipe 52 and the third connector pipe 53 are arranged side by side and have the same extension direction, which facilitates centralized pipe laying.

[0108] For example, referring to Figures 5 and 6, multiple connector tubes 50 are bent to the same side in the direction from the housing 10 away from the housing 10. Bending to the same side facilitates avoidance of other structures of the garment handling equipment during installation. Of course, in other embodiments, the first connector tube 51, the second connector tube 52, and the third connector tube 53 may all be straight tubes without bending, or may all be composed of multiple straight tubes connected in multiple directions, with the joints between the straight tubes connected by bends.

[0109] For example, in an embodiment where the centerlines of multiple connector tubes 50 along their extension directions are located in the same plane, referring to FIG5, each connector tube 50 is equidistant from the side of the top wall 14 near the second side wall 13 along the axial direction of the door seal ring 200, and is also equidistant from the side of the top wall 14 near the first side wall 12 along the axial direction of the door seal ring 200.

[0110] As an optional embodiment, the top wall 14 of the shell 10, as well as the first connector tube 51, the second connector tube 52, and the third connector tube 53, can be an integral structural component. The nozzle 40 is mounted on the top wall 14 of the shell 10. The bottom wall 15 of the shell 10, as well as the first side wall 13, the second side wall 12, and the two end plates 11, are integral structural components. The guide portion 60 can be integrated with the second side wall 12 using a two-color injection molding process to form an integral structural component.

[0111] In some embodiments, the nozzle unit 100 further includes a turbulence structure 80 disposed in the second connector tube 52 for providing a circumferential velocity component to the fluid in the second connector tube 52.

[0112] The aforementioned circumferential velocity component refers to the fluid in the second connector pipe 52 after passing through the turbulent structure 80, whose velocity direction has a non-zero component in the circumferential direction of the second connector pipe 52, and the circumferential direction of the second connector pipe 52 is perpendicular to the extension direction of the second connector pipe 52.

[0113] In this embodiment, the turbulent structure 80 allows some of the fluid to have both a circumferential velocity and a forward flow velocity, so some of the fluid moves in a roughly spiral motion. When the fluid is ejected from the outlet end of the second connector pipe 52, it facilitates the conical diffusion of the fluid, resulting in a wider radiation range and better visual effect.

[0114] For example, the turbulent structure 80 includes one or more helical blades that divide at least a portion of the length of the second connector pipe 52 into multiple sub-channels. "Multiple" refers to the number of blades, which can be two, three, or more; that is, the number of helical heads is not less than two, but it is not limited to the number of helical turns. After passing through the helical blades, the fluid exhibits a helical motion. The helical blade structure is simple, has a good turbulence effect on the fluid, and low resistance, reducing energy loss as the fluid passes through.

[0115] In some embodiments, the door seal ring 200 has an air inlet 200a and a plurality of mounting holes. Exemplarily, in one embodiment, the drying tunnel assembly communicates with the air inlet 200a and introduces a dry hot airflow into the garment processing chamber through the air inlet 200a to dry the garments in the garment processing chamber.

[0116] Referring to Figures 1 and 7, the housing 10 is located radially inside the door seal ring 200. Multiple connector tubes 50 pass through corresponding mounting holes to confine the nozzle unit 100 circumferentially on the door seal ring 200. Referring to Figures 3, 13, and 14, the end of each connector tube 50 away from the housing 10 extends towards the air inlet 200a, meaning the end of the connector tube 50 away from the housing 10 is closer to the air inlet 200a. Thus, on the radially outer side of the door seal ring 200, the side of the multiple connector tubes 50 away from the air inlet 200a frees up some installation space, facilitating the arrangement of other components, such as balance weights and detergent dispensers. This structure helps the multiple connector tubes 50 avoid structures such as balance weights and detergent dispensers, reducing the impact of the multiple connector tubes 50 on the installation space of existing structures within the garment processing equipment.

[0117] In some embodiments, referring to FIG2, the connector tube 50 includes a tube body 504 and a plug-in positioning part 503. The plug-in positioning part 503 surrounds the outer periphery of the tube body 504 and protrudes from the outer peripheral surface of the tube body 504. The plug-in positioning part 503 is located radially outside the door seal ring 200. The plug-in positioning part 503 limits the nozzle unit 100 along the extension direction of the connector tube 50, so that the nozzle unit 100 can be fixed on the door seal ring 200.

[0118] It should be noted that the door seal ring 200 is elastic; for example, it can be a rubber or silicone part. The inner diameter of the mounting hole is smaller than the outer diameter of the insertion positioning part 503, and the inner diameter of the mounting hole is also smaller than the outer diameter of the tube body 504.

[0119] For example, during assembly, the tube body 504 is passed through the mounting hole from the radial inner side to the radial outer side of the door seal ring 200. When the insertion positioning part 503 passes through the mounting hole, the insertion positioning part 503 will increase the elastic deformation of the door seal ring 200. When the insertion positioning part 503 passes out of the mounting hole, the hole wall of the mounting hole will at least partially recover its elastic deformation, thereby causing the insertion positioning part 503 to abut against the outer end face of the mounting hole. At this time, the insertion positioning part 503 and the top wall 14 hold the door seal ring 200 between them radially, thereby achieving the positioning of the nozzle unit 100 and the door seal ring 200.

[0120] In some embodiments, referring to FIG2, the tube body 504 includes an insertion section and a connecting section, wherein the insertion section is located between the insertion positioning part 503 and the shell part 10, and the connecting section is connected to the end of the insertion section away from the shell part 10, and the insertion section passes through the mounting hole. The end of the tube body 504 away from the shell part 10 extends in a direction close to the air inlet 200a.

[0121] In some embodiments, the end of the interpenetrating section away from the housing 10 extends toward the air inlet 200a.

[0122] In some embodiments, the end of the connecting section away from the intersecting section extends toward the air inlet 200a.

[0123] In some embodiments, the end of the interpenetrating section away from the shell 10 and the end of the connecting section away from the interpenetrating section both extend toward the air inlet 200a.

[0124] In some embodiments, both the interlacing segment and the connecting segment extend in a straight line, and the center lines of the interlacing segment and the connecting segment are not collinear. That is, the extension direction of the interlacing segment is different from that of the connecting segment. For example, the connecting segment extends closer to the air inlet 200a, making the distribution of the connecting segment and the air inlet 200a on the door seal ring 200 more compact. The fact that both the interlacing segment and the connecting segment extend in a straight line facilitates smooth demolding during the molding process, which is beneficial for manufacturing. The different extension directions of the two segments also facilitate segmented adjustment of the overall extension direction of the pipe body 504.

[0125] In some embodiments, referring to Figure 4, one of the intersecting segment and the connecting segment extends along a straight line, while the other extends along a curve. This includes the intersecting segment extending along a straight line and the connecting segment extending along a curve; or, the intersecting segment extending along a curve and the connecting segment extending along a straight line. The curved extension allows for more space to be freed up for the pipe segment corresponding to the pipe body 504, further avoiding other structures.
