[0050] This application provides a garment processing device, which includes a housing and a workbench 80. The workbench 80 is disposed on the housing. The housing provides support for the workbench 80.

[0051] The workbench 80 can be located on the upper part of the box. It can be understood that the projection plane is a plane perpendicular to the front-back direction, and the bisector is a straight line extending horizontally and bisecting the projection of the box. The upper part of the box can be the part of the box located above the bisector.

[0052] In some embodiments, the housing may be approximately hexahedral in shape, such as a cube or a cuboid.

[0053] The garment processing equipment includes a garment processing chamber, a worktable 80, and a housing that together define a placement chamber, within which the garment processing chamber is located. The garment processing chamber is used to place garments.

[0054] The garment handling equipment can be a top-loading washing machine. The garment handling chamber of a top-loading washing machine rotates about an axis extending in the vertical direction.

[0055] The garment processing equipment includes a drum assembly having a garment processing chamber, and the drum assembly is placed in the placement chamber.

[0056] Referring to Figure 1, the workbench 80 has a clothing inlet 80a that extends through both surfaces of the workbench 80 in the vertical direction and communicates with the clothing processing chamber. Clothes can be placed into or removed from the clothing processing chamber through the clothing inlet 80a. The workbench 80 constitutes the exterior surface of the clothing processing equipment.

[0057] The garment handling equipment includes a door that can selectively open or close the garment loading port 80a. For example, one end of the door can be rotatably connected to the worktable 80. This improves ease of operation.

[0058] The workbench 80 can also be used to install components such as control panels, which can be used to control the operation of the clothing processing equipment.

[0059] In some embodiments, the drum assembly includes a rotatable inner drum. The inner drum has an inlet / outlet that can face upwards. A user can insert or remove clothing from the inner drum from above via the clothing inlet 80a and the inlet / outlet. The inner drum can be used to hold loads such as clothing. The inner drum can rotate; for example, clothing, water, and detergent rotate with the inner drum, thus causing the clothing to continuously change its position within the inner drum, and the water and detergent to change their flow direction.

[0060] The space inside the inner drum can serve as a clothes handling chamber. The axis of the drum assembly can extend vertically, and the worktable 80 can be positioned above the drum assembly. A rotatable impeller can be installed inside the clothes handling chamber, such as inside the inner drum, to agitate the clothes, water, and detergent within the drum assembly.

[0061] In some embodiments, the inner cylinder may be generally hollow and cylindrical.

[0062] In some embodiments, the tub assembly includes an outer tub, and an inner tub may be disposed within the outer tub. The outer tub is used to hold water for washing clothes, and the inner tub is used to hold the clothes.

[0063] In this embodiment, water is contained in the outer tub, and the inner tub can also be referred to as a perforated inner tub. The space inside the inner tub is part of the garment processing chamber. Fluid can flow through the flow holes in the inner tub between the space between the outer tub and the inner tub, and between the space inside the inner tub.

[0064] In some embodiments, the outer barrel may be generally hollow and cylindrical.

[0065] It should be noted that, for ease of understanding, the first water channel 40A and the overflow water channel 180A of this application are schematically shown in Figures 4 and 16 of this application by means of dashed arrows.

[0066] Please refer to Figures 1 to 16. This application embodiment provides a dispensing component for a garment processing device. The dispensing component includes a first water channel 40A and an overflow water channel 180A. At least a portion of the sidewall of the first water channel 40A is formed by the worktable 80 of the garment processing device, and the first water channel 40A is used to convey a detergent mixture solution. The overflow water channel 180A is used to collect the detergent mixture solution overflowing from the first water channel 40A.

[0067] At least a portion of the sidewalls of the first waterway 40A are formed by the worktable 80, that is, at least a portion of the sidewalls of the first waterway 40A are constituted by the solid structure of the worktable 80.

[0068] The overflow water path 180A is used to receive the detergent mixture overflowing from the first water path 40A. This means that when the level of the detergent mixture in the first water path 40A is not higher than the overflow level, the detergent mixture is basically transported to the garment processing chamber through the first water path 40A; when the level of the detergent mixture in the first water path 40A is higher than the overflow level, the excess detergent mixture in the first water path 40A overflows into the overflow water path 180A and enters the garment processing chamber through the overflow water path 180A.

[0069] It is understood that the overflow level can be set according to requirements, and this application does not limit it.

[0070] The dispensing component provided in this application embodiment has two aspects. First, when the detergent mixture level in the first water channel 40A is higher than the overflow level, excess detergent mixture in the first water channel 40A overflows into the overflow water channel 180A and enters the garment processing chamber through the overflow water channel 180A. The overflow water channel 180A provides a safety protection function, ensuring timely discharge of excess detergent mixture in the first water channel 40A. Compared to related technologies that use only one outlet for detergent dispensing, both the first water channel 40A and the overflow water channel 180A in this application are used to dispense detergent mixture into the garment processing chamber, enriching the dispensing path of the detergent mixture. Second, at least a portion of the sidewall of the first water channel 40A is formed by the worktable 80, which reduces the number of pipes installed on the worktable 80.

[0071] It should be noted that the detergent mixture mentioned in this application is merely for ease of description and refers to a mixture containing dissolved detergent. Its mass percentage concentration is not limited, and the detergent mixture does not necessarily mean that the detergent is completely dissolved. In some embodiments, the detergent mixture may be undiluted detergent added by the user. In other embodiments, the detergent mixture may be a mixture of detergent and a fluid from a water source.

[0072] The function of detergent is not limited. For example, the function of detergent includes, but is not limited to, cleaning, softening or fragrance.

[0073] The type of detergent is not limited, and detergents include, but are not limited to, cleaning agents, fabric softeners, and / or fragrances, etc.

[0074] The form of detergent is not limited; it can be powdered laundry detergent or liquid laundry detergent that can be dispensed.

[0075] This application provides a garment processing device, which includes a garment processing chamber, a workbench 80, and a dispensing component as described in any embodiment of this application. The detergent mixture from the first water channel 40A and the detergent mixture from the overflow water channel 180A both enter the garment processing chamber.

[0076] In the garment processing device provided in this application embodiment, when the detergent mixture level in the first water channel 40A is higher than the overflow level, the excess detergent mixture in the first water channel 40A overflows into the overflow water channel 180A and enters the garment processing chamber through the overflow water channel 180A. The overflow water channel 180A serves as a safety protection function, ensuring timely discharge of excess detergent mixture in the first water channel 40A. Compared to related technologies that use only one outlet for detergent dispensing, both the first water channel 40A and the overflow water channel 180A in this application are used to dispense detergent mixture into the garment processing chamber, thus enriching the dispensing paths for the detergent mixture.

[0077] Please refer to Figures 1 to 3. A partition 150 is provided on the lower side of the workbench 80. The partition 150 and the workbench 80 together define a portion of the first water passage 40A. That is, the partition 150 and the workbench 80 enclose a channel for the flow of detergent mixture solution, and the solid structure of the partition 150 and the solid structure of the workbench 80 constitute the sidewall of the channel. By using the partition 150 and the workbench 80 to define the channel, the number of pipes laid on the workbench 80 can be reduced, the pipe layout can be simplified, and the manufacturing difficulty can be reduced.

[0078] The partition 150 and the worktable 80 can be detachably or non-detachably connected. In some embodiments, the partition 150 and the worktable 80 can be welded or bonded. In some embodiments, the partition 150 and the worktable 80 can be snap-fitted, screwed, or bolted, etc.

[0079] The connection between the partition 150 and the worktable 80 can be sealed. This prevents fluid leakage at the connection between the partition 150 and the worktable 80.

[0080] For example, the connection between the partition 150 and the worktable 80 can be sealed by welding, adhesive bonding, or a sealing element. The sealing element can be a flexible structure that uses its elastic deformation to seal the gap at the connection between the partition 150 and the worktable 80. For example, the sealing element can be a flexible structure made of rubber and / or silicone.

[0081] In one embodiment, referring to Figures 12 to 16, a portion of the worktable 80 is recessed to form part of the first water channel 40A. For example, a portion of the worktable 80 is recessed to form part of the first water channel 40A. That is, the partition 150 can be omitted, and the worktable 80 can be used entirely to form a channel for the flow of detergent mixture solution. The solid structure of the worktable 80 constitutes the sidewall of the channel, thus saving parts and reducing costs.

[0082] In one embodiment, referring to Figures 1, 4 and 16, the first water channel 40A includes a detergent dispensing chamber 140a and a mixing chamber 30d. The detergent dispensing chamber 140a is used to hold detergent and has an outlet 140b that communicates with the mixing chamber 30d. At least a portion of the sidewall of the mixing chamber 30d is formed by a worktable 80.

[0083] The detergent dispensing chamber 140a can be used to hold powdered laundry detergent. Of course, the detergent dispensing chamber 140a can also be used to hold detergents with flow characteristics, such as liquid laundry detergent.

[0084] The outlet 140b is used to discharge fluid, such as detergent, from the detergent dispensing chamber 140a. The outlet 140b connects the detergent dispensing chamber 140a and the mixing chamber 30d. The mixing chamber 30d is located downstream of the detergent dispensing chamber 140a. The detergent in the detergent dispensing chamber 140a enters the mixing chamber 30d through the outlet 140b. The mixing chamber 30d is used to hold the detergent mixture solution.

[0085] The fluid in mixing chamber 30d enters the garment processing chamber. In other words, the detergent mixture in mixing chamber 30d eventually enters the garment processing chamber to process the garments.

[0086] At least a portion of the sidewalls of the mixing chamber 30d are formed by the worktable 80, that is, the solid structure of the worktable 80 constitutes at least a portion of the sidewalls of the mixing chamber 30d.

[0087] In this embodiment, the detergent in the detergent dispensing chamber 140a enters the mixing chamber 30d for further mixing. The mixing chamber 30d can provide space for the detergent to dissolve further, thereby improving the uniformity of the detergent mixture solution.

[0088] In one embodiment, referring to Figures 1 to 16, the dispensing component includes a detergent box 30 and a dispenser box 140 disposed in the detergent box 30. The dispenser box 140 forms a detergent dispensing chamber 140a, and the detergent box 30 forms a mixing chamber 30d. At least a portion of the detergent box 30 is formed on the worktable 80.

[0089] The statement that at least a portion of the detergent dispenser 30 is formed on the worktable 80 means that a portion of the solid structure of the worktable 80 constitutes at least a portion of the solid structure of the detergent dispenser 30. For example, at least a portion of the detergent dispenser 30 may be integrally molded with the worktable 80. Exemplarily, at least a portion of the detergent dispenser 30 and the worktable 80 may be integrally injection molded.

[0090] In this embodiment, at least a portion of the detergent dispenser 30 is formed on the workbench 80. The workbench 80 partially reuses its structure as at least a portion of the detergent dispenser 30, which reduces the number of parts, simplifies the structure, and saves costs. The dispenser box 140 is movably disposed within the detergent dispenser 30, meaning the dispenser box can enter or exit the detergent dispenser 30. Thus, the dispenser box 140 can move relative to the detergent dispenser 30 to facilitate the dispensing of detergent into the detergent dispensing chamber 140a.

[0091] It should be noted that the detergent box 30 in this application can also be referred to as the nozzle body.

[0092] In some embodiments, the upper surface of the dispenser box 140 forms a dispensing port that communicates with the detergent dispensing chamber 140a. The user can add detergent to the detergent dispensing chamber 140a from above through the dispensing port.

[0093] In some embodiments, the detergent in the detergent dispensing chamber 140a can be flushed with water to allow the detergent to enter the mixing chamber 30d. For example, a spray nozzle can spray water into the detergent dispensing chamber 140a, and the water flow impacts and washes the detergent in the dispensing chamber to generate a detergent mixture solution. The detergent mixture solution then enters the mixing chamber 30d through the outlet 140b.

[0094] In some embodiments, the spray nozzle may be formed on the worktable 80.

[0095] In one embodiment, the spray nozzle may be located above the detergent dispensing chamber 140a.

[0096] The number of detergent dispensing chambers 140a is unlimited; there can be one or more. Taking multiple detergent dispensing chambers 140a as an example, the multiple detergent dispensing chambers 140a can be arranged sequentially in a direction perpendicular to the vertical direction, such as in a left-right direction or a front-back direction. Each detergent dispensing chamber 140a can dispense detergents with different or the same functions.

[0097] In some embodiments, the worktable 80 forms a downward-opening slot, and the partition 150 closes the downward opening of the slot to form the liquid outlet channel 130b of the nozzle 130 and the mixing chamber 30d of the detergent box 30.

[0098] In one embodiment, referring to Figures 1 and 2, the dispenser box 140 is removably disposed within the detergent dispenser 30. For example, at least a portion of the dispenser box 140 can be pulled out to the outside of the detergent dispenser 30, allowing the user to dispense detergent into the detergent dispensing chamber 140a. When dispensing is finished or when washing clothes is required, the dispenser box 140 can be pushed into the detergent dispenser 30, for example.

[0099] In one embodiment, referring to Figures 12 to 16, the dispensing assembly includes a water-blocking rib 170 and a detergent box 30. The detergent box 30 has a cavity, and at least a portion of the detergent box 30 is formed on the workbench 80. The water-blocking rib 170 extends upward from the wall of the cavity to divide the cavity into a sub-cavity and an overflow cavity 30c. The sub-cavity is part of a first water passage 40A, and the overflow cavity 30c is part of an overflow water passage 180A.

[0100] In this embodiment, the height of the baffle 170 in the vertical direction is the height of the overflow liquid level. The upper surface of the baffle 170 is spaced apart from the surface of the cavity, that is, there is a gap between the upper surface of the baffle 170 and the surface of the cavity. The liquid level of the detergent mixture in the sub-cavity is higher than the height of the baffle 170 in the vertical direction, and the detergent mixture in the sub-cavity passes over the upper surface of the baffle 170 and enters the overflow cavity 30c through the gap between the upper surface of the baffle 170 and the surface of the cavity.

[0101] In one embodiment, please refer to Figures 1 to 16. The dispensing component includes a second water channel 50A and a mixing space 20a. The second water channel 50A is used to transport water. The outlet of the first water channel 40A and the outlet of the second water channel 50A are both connected to the mixing space 20a.

[0102] The fluid from the first water channel 40A and the fluid from the second water channel 50A both enter the mixing space 20a and then enter the garment processing chamber to participate in garment processing.

[0103] In this embodiment, the fluid from the second water channel 50A and the fluid from the first water channel 40A both enter the mixing space 20a and converge and mix, thereby improving the mixing effect and allowing the detergent, such as laundry powder, to dissolve more fully.

[0104] The outlet of the first water channel 40A refers to the point where the fluid in the first water channel 40A leaves the first water channel 40A. The outlet of the second water channel 50A refers to the point where the fluid in the second water channel 50A leaves the second water channel 50A.

[0105] In one embodiment, referring to Figures 1 to 16, the dispensing component includes a nozzle 130, at least a portion of which is formed on the worktable 80, and the nozzle 130 has a portion of a first water passage 40A.

[0106] The statement that at least a portion of the nozzle 130 is formed in the worktable 80 means that a portion of the solid structure of the worktable 80 constitutes at least a portion of the solid structure of the nozzle 130. In other words, at least a portion of the nozzle 130 and the worktable 80 can be integrally molded, for example, at least a portion of the nozzle 130 and the worktable 80 can be integrally injection molded.

[0107] In this embodiment, at least a portion of the nozzle 130 is formed on the worktable 80, and a portion of the structure of the worktable 80 is reused as at least a portion of the nozzle 130, which can reduce the number of parts, simplify the structure, and save costs.

[0108] In one embodiment, referring to Figures 1 to 16, the dispensing component includes a tube 131, which forms at least a portion of a second water passage 50A. At least a portion of the tube 131 is inserted into a first water passage 40A. The insertion of at least a portion of the tube 131 into the first water passage 40A can be either a partial insertion or the complete insertion of the tube 131. Insertion of a portion of the tube 131 into the first water passage 40A facilitates connection of the portion of the tube 131 outside the first water passage 40A to other pipes or valves, etc.

[0109] The insertion of at least a portion of the insertion tube 131 into the first water passage 40A can be achieved by connecting the insertion tube 131 and the first water passage 40A together. This connection method is simple, easy to operate, and can reduce assembly difficulty.

[0110] For example, the nozzle 130 forms a liquid outlet channel 130b, which is part of the first water path 40A, and at least a portion of the insertion tube 131 is inserted into the liquid outlet channel 130b.

[0111] In this embodiment, the outlet end of the insertion tube 131 is the outlet end of the second water channel 50A. The space within the insertion tube 131 forms at least a portion of the second water channel 50A, resulting in a simple structure that is easy to manufacture. Inserting at least a portion of the insertion tube 131 into the first water channel 40A facilitates the entry of water from the insertion tube 131 into the first water channel 40A, thereby impacting the detergent mixture in the first water channel 40A and further diluting the detergent.

[0112] In one embodiment, referring to Figures 1 to 16, the nozzle 130 forms a mixing space 20a and a liquid outlet 20ab communicating with the mixing space 20a. The mixing space 20a is located between the water outlet end of the second water path 50A and the liquid outlet 20ab. The liquid outlet 20ab is used to discharge the fluid in the mixing space 20a. The fluid from the first water path 40A and the fluid from the second water path 50A converge and mix in the mixing space 20a, and then are discharged through the liquid outlet 20ab into the clothing processing chamber to participate in clothing processing.

[0113] In one embodiment, referring to Figures 1 to 16, a liquid outlet 20ab is formed on the worktable 80, facilitating the downward spraying of fluid discharged from the liquid outlet 20ab into the clothing processing chamber under the action of gravity and initial velocity. At least a portion of the space between the water outlet of the second water channel 50A and the liquid outlet 20ab is a mixing space 20a.

[0114] For example, in some embodiments, referring to Figures 11 and 16, the mixing space 20a can be the space defined by the line connecting the water outlet of the second water channel 50A and the liquid outlet 20ab. Referring to Figure 11, the space defined by the dashed line between the water outlet of the second water channel 50A and the liquid outlet 20ab is the mixing space 20a. The water outlet of the second water channel 50A can be the boundary between the second water channel 50A and the mixing space 20a; that is, the water outlet of the first water channel 40A surrounds the mixing space 20a.

[0115] The outlet 20ab is a through hole penetrating the outer surface of the solid portion. In some embodiments, as shown in Figures 3 and 11, the outlet 20ab is formed on the surface of the worktable 80 facing the clothing inlet 80a. This minimizes the risk of the structure on the worktable 80 obstructing the discharge of fluid from the outlet 20ab.

[0116] In one embodiment, referring to Figures 3, 5, and 11, the outlet 20ab is inclined downwards and forwards towards the garment processing chamber. That is, the axis of the outlet 20ab is oblique to a straight line extending in the vertical direction, thus facilitating a large-scale coverage of the garments in the garment processing chamber by the detergent mixture sprayed from the outlet 20ab.

[0117] In one embodiment, the flow velocity at the outlet of the second water channel 50A is greater than that at the outlet of the first water channel 40A. On one hand, the velocity difference between the fluid discharged from the second water channel 50A and the fluid discharged from the first water channel 40A, with the relatively higher flow velocity at the outlet of the second water channel 50A, increases the impact force of the fluid. The two fluids entering the mixing space 20a have different flow velocities, with the faster flow impacting and disturbing the slower flow, allowing for better mixing of the detergent when the two fluids converge, further promoting detergent dissolution. On the other hand, the relatively higher flow velocity at the outlet of the second water channel 50A generates negative pressure in the surrounding area, causing the fluid at the outlet of the first water channel 40A to be drawn in under this negative pressure, improving the mixing effect.

[0118] In one embodiment, the outlet end of the second water channel 50A is inserted into the first water channel 40A. For example, the wall of the first water channel 40A has a socket, and the second water channel 50A is inserted into the socket and extends into the first water channel 40A. In this way, the fluid in the second water channel 50A and the fluid in the first water channel 40A can quickly come into contact and mix.

[0119] In some embodiments, the connection between the second water passage 50A and the first water passage 40A is sealed. For example, the connection between the second water passage 50A and the socket is sealed.

[0120] The sealing method at the connection between the second water channel 50A and the first water channel 40A is not limited. For example, the connection between the second water channel 50A and the first water channel 40A can be sealed by a sealing structure. For instance, a sealing structure can be provided between the outer peripheral surface of the second water channel 50A and the surface of the insertion hole.

[0121] The sealing structure can be a flexible structure, utilizing its elastic deformation to seal the gap at the connection between the second water channel 50A and the first water channel 40A. For example, the sealing structure can be a flexible structure made of rubber and / or silicone.

[0122] In one embodiment, the outlet of the second water channel 50A is inserted into the first water channel 40A, and the mixing space 20a can be located within the first water channel 40A. The mixing space 20a is located downstream of the outlet of the second water channel 50A and is disposed within the first water channel 40A. The mixing space 20a is defined by the outlet of the second water channel 50A and the wall of the first water channel 40A. The fluid from the second water channel 50A impacts the detergent mixture solution within the mixing space 20a, thereby accelerating detergent dissolution, improving the uniformity of detergent-water mixing, and thus improving detergent utilization efficiency and washing ratio.

[0123] In one embodiment, referring to Figures 2, 7, 8, and 11, the insertion tube 131 forms a liquid flow channel 130a, which is part of the second water passage 50A. The insertion tube 131 is inserted into the workbench 80. That is, the workbench 80 has an insertion hole, and the insertion tube 131 is inserted into the insertion hole. This design utilizes the workbench 80 to provide an installation position for the insertion tube 131, simplifying the installation process and improving production efficiency.

[0124] In one embodiment, the partition 150 forms a socket, and the insertion tube 131 is inserted into the socket.

[0125] In some embodiments, the gap between the cannula 131 and the insertion hole can be sealed by a sealing structure. For example, the gap between the cannula 131 and the insertion hole can be sealed by a sealing ring.

[0126] In one embodiment, referring to Figures 2, 7, 8, and 11, the insertion tube 131 includes a horizontal section 1311 and a bent section 1312 connected to the horizontal section 1311. The axis of the horizontal section 1311 extends horizontally, and the bent section 1312 bends downward from the horizontal section 1311. The outlet end of the second water passage 50A is formed in the bent section 1312. Exemplarily, the end of the bent section 1312 away from the horizontal section 1311 is the outlet end of the second water passage 50A. The horizontal section 1311 facilitates insertion into the insertion hole. The bent section 1312 causes the fluid to flow downward, thereby facilitating downward spraying of the outlet end of the second water passage 50A, so that the fluid can quickly contact the clothing located below.

[0127] In one embodiment, the plane containing the outlet 20ab is used as the projection plane, and the projection of the outlet end of the second water path 50A is located within the projection range of the outlet 20ab. For example, the flow area of ​​the outlet 20ab can be larger than the flow area of ​​the outlet end of the second water path 50A. In this way, the misalignment between the outlet end of the second water path 50A and the outlet 20ab can be avoided, thus preventing a change in the fluid flow direction.

[0128] It should be noted that the flow cross-section is a section perpendicular to the streamline cluster. When the streamline clusters are not parallel to each other, the flow cross-section is curved; when the streamline clusters are parallel straight lines, the flow cross-section is a plane. The flow area refers to the area of ​​the flow cross-section. Taking the circular outlet 20ab as an example, the flow area of ​​the outlet 20ab can be the area of ​​a circle.

[0129] In one embodiment, referring to Figures 1 to 11, a portion of the partition 150 and the worktable 80 define a portion of the detergent dispenser 30, and another portion of the partition 150 and the worktable 80 define a nozzle 130. Exemplarily, with a plane perpendicular to the vertical direction as the projection plane, the dispenser box 140 is in a state of being housed within the detergent dispenser 30, and the projection of the dispenser box 140 at least partially overlaps with the projection of the detergent dispenser 30, while the projection of the dispenser box 140 is spaced apart from the projection of the nozzle 130.

[0130] In one embodiment, both the detergent dispenser 30 and the spray nozzle 130 are formed by the worktable 80. That is, the worktable 80 does not have a partition 150, and the entirety of the detergent dispenser 30 and the entirety of the spray nozzle 130 are formed by the worktable 80.

[0131] In one embodiment, please refer to Figures 1 to 16. The surface of the workbench 80 facing the clothing inlet 80a has a pumping port 80b. The pumping port 80b communicates with the cavity of the detergent box 30. The sub-cavity is located on the side of the baffle 170 away from the pumping port 80b, and the overflow cavity 30c is located on the side of the baffle 170 close to the pumping port 80b.

[0132] The overflow chamber 30c and the extraction port 80b form an overflow water path 180A. The detergent mixture overflowing from the sub-chamber passes over the baffle 170 and enters the overflow chamber 30c, and then directly enters the garment processing chamber through the extraction port 80b.

[0133] The detergent dispensing chamber 140a, the sub-chamber, and the outlet channel 130b constitute the first water path 40A. The sub-chamber includes a receiving chamber 30e and a mixing chamber 30d. The receiving chamber 30e is located above the mixing chamber 30d, and the upper sidewall of the mixing chamber 30d forms a filter hole 160a. The detergent mixture in the detergent dispensing chamber 140a enters the receiving chamber 30e, and then enters the outlet channel 130b of the nozzle 130 through the mixing chamber 30d.

[0134] The filter pore 160a is used to limit the particle size of the flowing particles, thereby achieving a filtering effect.

[0135] Dispenser box 140 enters and exits detergent box 30 through extraction port 80b. When detergent needs to be added to dispenser box 140, dispenser box 140 can be extracted from detergent box 30 through extraction port 80b; after adding detergent, dispenser box 140 can be pushed into detergent box 30 through extraction port 80b. During washing, detergent and other fluids in detergent dispensing chamber 140a can flow through first water path 40A, for example, sequentially through receiving chamber 30e, mixing chamber 30d, liquid outlet channel 130b and mixing space 20a, and finally dispensed into clothing processing chamber from liquid outlet 20ab; detergent and other fluids in receiving chamber 30e can also overflow into overflow chamber 30c and enter clothing processing chamber through extraction port 80b.

[0136] In one embodiment, the insertion tube 131 is located on the left or right side of the detergent dispenser 30. Arranging the insertion tube 131 and the detergent dispenser 30 in a left-right direction reduces the dimensions they occupy in the vertical direction, thereby avoiding an excessive increase in the overall height of the workbench 80 in the vertical direction.

[0137] In some embodiments, the mixing space 20a may be located on one side of the dispenser box 140, and the detergent dispensing chamber 140a is connected to the mixing space 20a. The mixing space 20a and the dispenser box 140 are compactly arranged. The detergent mixture from the detergent dispensing chamber 140a flows a certain distance and time before entering the mixing space 20a, allowing the detergent mixture to further dissolve during the flow process and improving the mixing effect.

[0138] In some embodiments, the mixing space 20a is located to the left or right of the dispenser box 140. Arranging the mixing space 20a and the dispenser box 140 in a left-right direction reduces the dimensions they occupy in the vertical direction, thereby avoiding an excessive increase in the overall height of the worktable 80 in the vertical direction.

[0139] In some embodiments, referring to Figures 1 to 4, 9, and 16, the dispenser box 140 forms an outlet 140b communicating with the detergent dispensing chamber 140a. The outlet 140b is located on the side of the dispenser box 140 away from the liquid outlet 20ab. The outlet 140b is used to discharge the detergent mixture solution in the detergent dispensing chamber 140a. The outlet 140b communicates with the mixing space 20a; for example, a first water passage 40A connects the outlet 140b and the mixing space 20a. The detergent mixture solution from the outlet 140b first enters the mixing space 20a through the first water passage 40A, and then is discharged into the laundry treatment chamber through the liquid outlet 20ab. The outlet 140b is located on the side of the distributor box 140 away from the liquid outlet 20ab. The path between the outlet 140b and the liquid outlet 20ab is moderate, which extends the flow path of the detergent mixture in a limited space. The flow path and flow time of the detergent mixture are appropriate, which facilitates further dissolution of the detergent mixture during the flow process, thereby improving the mixing effect.

[0140] For example, in some embodiments, the outlet 140b is formed on the rear sidewall of the dispenser box 140, and the liquid outlet 20ab is formed on the front sidewall of the workbench 80 facing the clothing inlet 80a.

[0141] In some embodiments, referring to Figures 4 to 6 and Figure 16, the sub-cavity includes a receiving cavity 30e and a mixing cavity 30d, with the mixing cavity 30d located below the receiving cavity 30e. A filter hole 160a is formed on the upper sidewall of the mixing cavity 30d, connecting the receiving cavity 30e and the mixing cavity 30d. The dispenser box 140 can enter and exit the receiving cavity 30e. The detergent mixture from the detergent dispensing chamber 140a first flows through the receiving cavity 30e, is filtered through the filter hole 160a, and then enters the mixing cavity 30d.

[0142] In this embodiment, taking laundry detergent as an example, the water flow impacts and dissolves the laundry detergent in the detergent dispensing chamber 140a. Because the water flow impacts the laundry detergent in the detergent dispensing chamber 140a for a relatively short time, insufficient dissolution of the laundry detergent is likely. The filter hole 160a can temporarily retain particles larger than or equal to the pore size of the filter hole 160a on the upper sidewall of the mixing chamber 30d, while particles smaller than the pore size of the filter hole 160a can enter the mixing chamber 30d and then enter the clothing processing chamber through the liquid outlet 20ab. During the washing process, the detergent mixture from the detergent dispensing chamber can repeatedly rinse the laundry detergent on the upper sidewall of the mixing chamber 30d, allowing the laundry detergent to dissolve again before re-entering the mixing chamber 30d. This design results in better dissolution of the laundry detergent, and the laundry detergent particles entering the clothing processing chamber are relatively small, improving the cleaning effect.

[0143] In some embodiments, referring to Figures 5 through 16, the dispensing assembly includes a filter plate 160, which forms the upper sidewall of the mixing chamber 30d. Exemplarily, at least a portion of the filter plate 160 is located between the lower surface of the detergent dispensing chamber 140a and the sub-chamber. Specifically, the space defined by the filter plate 160 and the lower surface of the sub-chamber is the mixing chamber 30d. The filter plate 160 is used to filter the detergent mixture solution from the detergent dispensing chamber 140a. The detergent mixture solution from the detergent dispensing chamber 140a first flows through the filter plate 160, is filtered by the filter plate 160, and then enters the mixing chamber 30d.

[0144] In this embodiment, taking laundry detergent as an example, the water flow impacts and dissolves the laundry detergent in the detergent dispensing chamber 140a. Because the water flow impacts the laundry detergent in the detergent dispensing chamber 140a for a relatively short time, insufficient dissolution of the laundry detergent is likely to occur. The filter plate 160 can temporarily retain particles larger than or equal to the pore size of the filter holes 160a on its upper surface, while particles smaller than the pore size of the filter holes 160a can enter the mixing chamber 30d and then enter the clothing processing chamber through the outlet 20ab. During the washing process, the detergent mixture from the detergent dispensing chamber can repeatedly rinse the laundry detergent on the upper surface of the filter plate 160, allowing the laundry detergent to dissolve again before entering the mixing chamber 30d. This design results in better dissolution of the laundry detergent, and the laundry detergent particles entering the clothing processing chamber are relatively small, improving the cleaning effect.

[0145] Understandably, the aperture size and shape of the filter hole 160a can be set as needed. The shape of the filter hole 160a includes, but is not limited to, circles, ovals, polygons, or irregular shapes. Irregular shapes refer to irregular shapes.

[0146] In some embodiments, with the dispenser box 140 housed within the detergent box 30, the projection of the outlet 140b and the filter hole 160a do not overlap, using a plane perpendicular to the vertical direction as the projection plane. That is, the projection of the outlet 140b and the filter hole 160a are spaced apart. This design ensures that the fluid from the outlet 140b first contacts the solid portion of the filter plate 160 without the filter hole 160a, and then flows to the location of the filter hole 160a. This can, to a certain extent, prevent the detergent mixture from the outlet 140b from directly impacting the filter hole 160a, thus avoiding particles larger than the pore size of the filter hole 160a from being flushed into the mixing chamber 30d.

[0147] In some embodiments, referring to Figure 6, at least a portion of the lower surface of the mixing chamber 30d slopes downward from away from the nozzle 130 toward closer to the nozzle 130 to form a guide surface 130ba. In this way, the fluid in the mixing chamber 30d can smoothly and quickly enter the nozzle 130 under the guidance of the guide surface 130ba, and the residual fluid in the mixing chamber 30d can also be reduced.

[0148] In some embodiments, referring to Figures 5 and 6, the filter plate 160 may be located above the guide surface 130ba. For example, with a plane perpendicular to the vertical direction as the projection plane, the projection of the filter plate 160 and the projection of the guide surface 130ba at least partially overlap.

[0149] In one embodiment, referring to Figures 2 to 16, the second water channel 50A is provided with a pressurizing structure 120 and / or a turbulent flow structure 21. The pressurizing structure 120 is used to increase the flow velocity of the fluid in the second water channel 50A, and the turbulent flow structure 21 is used to provide a circumferential velocity component to the fluid in the second water channel 50A.

[0150] The aforementioned circumferential velocity component refers to the fluid in the second water channel 50A after passing through the turbulent structure 21. The circumferential component of the velocity in the second water channel 50A is not zero, and the circumferential direction of the second water channel 50A surrounds the extension direction of the liquid flow channel 130a.

[0151] The fluid in the second water channel 50A has a greater impact force after being accelerated by the pressurization structure 120, which can better agitate the fluid from the first water channel 40A and improve the mixing effect.

[0152] After passing through the turbulent structure 21, the fluid in the second water channel 50A generates a complex motion in multiple directions, including the circumferential direction and the forward direction, thereby better mixing with the fluid in the mixing space 20a and improving the mixing efficiency; it also enables the fluid ejected from the outlet 20ab to spread out in a roughly cone shape, with a wider radiation range and better visual effect.

[0153] In this embodiment, the flow rate or shape of the fluid in the second water channel 50A is changed by the pressurization structure 120 and / or the turbulence structure 21 to better impact the detergent mixture solution, thereby accelerating the dissolution of the detergent and improving its uniformity.

[0154] Understandably, the turbulent structure 21 can also increase the fluid velocity by limiting the flow area of ​​the liquid flow channel 130a in which it is located. In this way, the velocity difference between the two fluid streams entering the mixing space 20a is further increased, which further promotes the dissolution of detergent.

[0155] In one embodiment, referring to Figures 4, 8, and 16, a fluid flow channel 130a is formed within the insertion tube 131. The fluid flow channel 130a is at least a part of the second water path 50A. The fluid flow channel 130a is provided with a pressurizing structure 120 and / or a turbulence structure 21. The pressurizing structure 120 is used to increase the flow velocity of the fluid in the fluid flow channel 130a. After the fluid in the fluid flow channel 130a is accelerated by the pressurizing structure 120, the impact force is greater, which can better agitate the fluid from the first water path 40A and improve the mixing effect.

[0156] In one embodiment, referring to Figures 8 and 11, the pressurizing structure 120 includes a narrowed section 22, which increases the flow velocity at the outlet of the second water path 50A. The narrowed section 22 refers to the section where the flow area of ​​the fluid decreases along the flow direction. By limiting the flow area, the narrowed section 22 increases the impact force of the fluid, resulting in a better mixing effect. Simultaneously, the narrowed section 22 gives the outlet of the second water path 50A a larger jet velocity, generating a significant negative pressure in a relatively large surrounding area. This negative pressure draws the fluid from the outlet of the first water path 40A into the second water path 50A, mixing it with the fluid in the second water path 50A and enhancing the mixing effect.

[0157] In some embodiments, the pressurization structure 120 includes a powered pressurization mechanism. A powered pressurization mechanism is a mechanism that uses a power source to increase fluid pressure and thus increase flow velocity. The power source includes, but is not limited to, electrical energy or other energy sources. The powered pressurization mechanism can actively increase fluid flow velocity, which, compared to the passive increase in fluid flow velocity by the narrowed section 22, offers a higher degree of automation.

[0158] The type of power pressurization mechanism is not limited. For example, power pressurization mechanisms include, but are not limited to, water pumps, peristaltic pumps, etc.

[0159] In some embodiments, the end of the pressurizing structure 120 forms the outlet of the second water passage 50A. That is, the fluid in the second water passage 50A is ejected directly from the end of the pressurizing structure 120, for example, the end of the narrowed section 22.

[0160] In some embodiments, please refer to Figures 7 and 8, the end of the pressurization structure 120 is connected to a constant diameter section 23 and / or an enlarged diameter section, which forms the outlet end of the second water passage 50A.

[0161] For example, the end of the pressurization structure 120 is connected to a constant diameter section 23, which forms the outlet of the second water passage 50A.

[0162] For example, the end of the pressurization structure 120 is connected to an expansion section, which forms the outlet of the second water passage 50A.

[0163] For example, the end of the pressurization structure 120 is connected to a constant diameter section 23 and an expanded diameter section, and either the constant diameter section 23 or the expanded diameter section forms the outlet end of the second water passage 50A.

[0164] The constant diameter section 23 refers to the section where the flow area of ​​the fluid remains basically unchanged along the flow direction.

[0165] An expansion section refers to a section where the flow area of ​​the fluid increases along the flow direction.

[0166] In this embodiment, the fluid in the second water channel 50A is directly ejected from the constant diameter section 23 and / or the expanding diameter section into the mixing space 20a. After being accelerated by the pressurization structure 120, the fluid flows through the constant diameter section 23 and / or the expanding diameter section, and the fluid can flow out into the mixing space 20a in a conical shape at a relatively fast speed.

[0167] In some embodiments, the extension length of the constant diameter section 23 along the second water passage 50A is less than or equal to the extension length of the narrow diameter section 22 along the second water passage 50A. Since the longer the fluid flow path, the more significant its energy loss, limiting the length of the constant diameter section 23 can reduce the loss of impact force after the fluid flows out of the narrow diameter section 22.

[0168] In some embodiments, the extension length of the expanding section along the second water passage 50A is less than or equal to the extension length of the narrowing section 22 along the second water passage 50A. Since the longer the fluid flow path, the more significant its energy loss, limiting the length of the expanding section can reduce the loss of impact force after the fluid flows out of the narrowing section 22.

[0169] In one embodiment, referring to Figures 8 and 11, the fluid channel 130a is provided with a turbulence structure 21, which is used to provide a circumferential velocity component to the fluid in the second water channel 50A.

[0170] The aforementioned circumferential velocity component refers to the fluid in the flow channel 130a after passing through the turbulent structure 21, whose velocity component in the circumferential direction of the flow channel 130a is not zero, and the circumferential direction of the flow channel 130a surrounds the extension direction of the flow channel 130a.

[0171] After passing through the turbulent structure 21, the fluid in the liquid flow channel 130a generates a composite motion in multiple directions, including the circumferential direction and the forward direction, thereby better mixing with the fluid in the mixing space 20a and improving the mixing efficiency; it also enables the fluid ejected from the outlet 20ab to spread out in a roughly cone shape, with a wider radiation range and better visual effect.

[0172] Understandably, the turbulent structure 21 can also increase the fluid velocity by limiting the flow area of ​​the second water channel 50A in which it is located. This results in a greater difference in velocity between the two fluid streams entering the mixing space 20a, further promoting detergent dissolution.

[0173] In some embodiments, referring to Figures 8 and 11, the turbulence structure 21 includes one or more helical blades for guiding the fluid in the second water passage 50A in a helical motion. A helical blade is a blade with a helical shape, extending in the helical direction. After passing through the helical blades, the fluid exhibits a helical motion with a circumferential velocity component. 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.

[0174] For example, the turbulent structure 21 includes one or more helical blades that divide at least a portion of the length of the second waterway 50A into multiple sub-channels.

[0175] The term "multiple" refers to the number of blades, which can be two, three, or more, meaning the number of spiral heads is not less than two, but does not limit the number of spiral turns.

[0176] In some embodiments, referring to Figures 8 and 11, the outer edge of the helical blade along the helical direction is connected to the inner wall of the second water passage 50A, and the inner edge of the helical blade along the helical direction is spaced apart from the inner wall of the second water passage 50A. That is, there is a gap between the inner edge of the helical blade and the inner wall of the second water passage 50A, so that the inner wall of the second water passage 50A provides a connection support for the helical blade.

[0177] In some embodiments, referring to Figures 8 and 11, the pressurization structure 120 is located downstream of the turbulence structure 21. The fluid passes sequentially through the turbulence structure 21 and the pressurization structure 120, such as the narrowed section 22, and is then ejected in a conical shape into the garment processing chamber.

[0178] In some embodiments, the distance between the turbulent flow structure 21 and the pressurizing structure 120 is greater than the distance between the outlet 20ab and the pressurizing structure 120. With this design, the fluid path between the turbulent flow structure 21 and the pressurizing structure 120 is greater than the fluid path between the pressurizing structure 120 and the outlet 20ab. This allows the fluid to be effectively accelerated by the turbulent flow structure 21 and the pressurizing structure 120, and to be discharged from the mixing space 20a in a timely manner, reducing losses during the flow process.

[0179] It should be noted that in the embodiments of this application, the first water path 40A refers to the flow path of the fluid and does not specifically refer to a pipe structure. The second water path 50A refers to the flow path of the fluid and does not specifically refer to a pipe structure. The overflow water path 180A refers to the flow path of the fluid and does not specifically refer to a pipe structure.

[0180] In some embodiments, the inlet of the first water channel 40A can be connected to a water source, and the inlet of the second water channel 50A can be connected to a water source.

[0181] It should be noted that the water source in this embodiment refers to the water source that supplies water flow to the first water channel 40A and / or the second water channel 50A, such as tap water; it can also be the internal water source of the clothing processing equipment, such as circulating water.

[0182] In one embodiment, referring to Figure 1, the garment processing device includes a water inlet valve 90, which is connected to a water source such as a tap water pipe. The first water path 40A and the second water path 50A can be connected to different water inlet valves 90, or they can be connected to the same water inlet valve 90; this is not limited here. As an optional embodiment, the garment processing device includes a circulation pump, with one of the first water path 40A and the second water path 50A connected to the water inlet valve 90, and the other connected to the circulation pump of the garment processing device.

[0183] In some embodiments, the inlet valve 90 has at least two water outlets, with the first water path 40A and the second water path 50A each connected to one of the water outlets. Water is supplied to the garment processing equipment through the inlet valve 90. The first water path 40A and the second water path 50A are each connected to one water outlet, and the flow rates at the different water outlets can be different, thus increasing the velocity difference between the first water path 40A and the second water path 50A.

[0184] In some embodiments, the inlet end of the insertion tube 131 is connected to a water outlet of the inlet valve 90. Thus, the inlet valve 90 can supply water to the insertion tube 131. The second water path 50A includes the insertion tube 131, into which the inlet valve 90 delivers water.

[0185] In some embodiments, a water inlet of the water inlet valve 90 can be connected via a water spray structure. The water spray structure has a spray nozzle that sprays water toward the detergent dispensing chamber 140a. The first water path 40A includes the detergent dispensing chamber 140a and the first water path 40A. Thus, by rinsing the detergent dispensing chamber 140a with water, the detergent solution is initially dissolved, and the detergent mixture in the detergent dispensing chamber 140a flows to the first water path 40A under the action of water flow.

[0186] Please refer to Figures 1 to 11. The dispensing component provided in this embodiment is disposed on the workbench 80. The dispensing component includes a detergent box 30 and a nozzle 130. The detergent box 30 forms an overflow water channel 180A. The nozzle 130 is located on one side outside the detergent box 30. Both the detergent box 30 and the nozzle 130 are constructed as part of a first water channel 40A. The first water channel 40A is used to transport detergent mixture solution, and the overflow water channel 180A is used to receive detergent mixture solution overflowing from the first water channel 40A.

[0187] Workbench 80 provides support and installation location for the delivery components.

[0188] The detergent cartridge 30 and the nozzle 130 both form part of the first water path 40A, that is, the detergent cartridge 30 and the nozzle 130 both have channels for the flow of detergent mixture solution, and the detergent mixture solution of the first water path 40A flows through the detergent cartridge 30 and the nozzle 130.

[0189] In this embodiment, the detergent dispenser 30 forms part of an overflow water path 180A and a first water path 40A, and the nozzle 130 forms part of the first water path 40A. Thus, the detergent mixture can be divided within the detergent dispenser 30, with one part entering the nozzle 130 and the other part entering the overflow water path 180A. When the detergent mixture level in the first water path 40A is higher than the overflow level, excess detergent mixture overflows into the overflow water path 180A and enters the garment processing chamber. The overflow water path 180A provides a safety protection function, promptly draining excess detergent mixture from the first water path 40A. Compared to related technologies that use only one outlet for detergent dispensing, this embodiment uses both the first water path 40A and the overflow water path 180A to dispense detergent mixture into the garment processing chamber, enriching the dispensing pathways for the detergent mixture.

[0190] The dispensing component is set on the worktable 80, and at least some of the components of the dispensing component can be fixed on the worktable 80. The fixing method includes, but is not limited to, detachable connection, non-detachable connection or integral molding manufacturing, etc.

[0191] In some embodiments, the nozzle 130 is located to the left or right of the detergent dispenser 30. Arranging the nozzle 130 and detergent dispenser 30 in a left-right direction reduces the dimensions they occupy in the vertical direction, thereby avoiding an excessive increase in the overall height of the workbench 80 in the vertical direction.

[0192] In some embodiments, referring to Figures 4 to 11, the nozzle 130 has a liquid outlet channel 130b, which is part of the first water path 40A. At least a portion of the insert 131 is inserted into the liquid outlet channel 130b. That is, the water outlet end 40Aa of the liquid outlet channel 130b is the water outlet end of the first water path 40A. The insert 131 is inserted into the nozzle 130, and the liquid from the insert 131 can easily and quickly come into contact with and mix with the detergent in the liquid outlet channel 130b, and is sprayed out through the nozzle 130 into the clothing processing chamber.

[0193] In some embodiments, referring to Figures 1 to 11, a partition 150 is provided on the lower side of the worktable 80, and the partition 150 and the worktable 80 together define the nozzle 130. That is, at least a portion of the solid structure of the partition 150 and a portion of the solid structure of the worktable 80 constitute the nozzle 130, and the partition 150 and the worktable 80 together enclose a channel for the flow of detergent mixture solution. By using the partition 150 and the worktable 80 to define the nozzle 130, the number of components arranged on the worktable 80 can be reduced, the layout can be simplified, and the manufacturing difficulty can be reduced.

[0194] In some embodiments, referring to Figures 1 to 11, the dispensing component includes a dispenser box 140 that is removably disposed in the detergent box 30. The dispenser box 140 forms a detergent dispensing cavity 140a for holding detergent. The detergent box 30 forms a mixing cavity 30d that communicates with the detergent dispensing cavity 140a. Both the detergent dispensing cavity 140a and the mixing cavity 30d are part of a first water path 40A.

[0195] In this embodiment, the detergent in the detergent dispensing chamber 140a enters the mixing chamber 30d for further mixing. The mixing chamber 30d provides space for further dissolution of the detergent, improving the uniformity of the detergent mixture. The dispenser box 140 is removably disposed within the detergent box 30, meaning that the dispenser box 140 can enter or exit the detergent box 30. Thus, the dispenser box 140 can move relative to the detergent box 30 to facilitate dispensing detergent into the detergent dispensing chamber 140a.

[0196] In some embodiments, the upper surface of the dispenser box 140 forms an addition port that communicates with the detergent dispensing chamber 140a. A user can add detergent to the detergent dispensing chamber 140a from above through the addition port.

[0197] In one embodiment, please refer to Figures 1 to 11, the detergent dispensing chamber 140a is located above the mixing chamber 30d, and the upper sidewall of the mixing chamber 30d is formed with filter holes 160a.

[0198] In this embodiment, the fluid in the detergent dispensing chamber 140a is filtered through the filter hole 160a before entering the mixing chamber 30d. Taking laundry detergent as an example, the water flow impacts and initially dissolves the laundry detergent in the detergent dispensing chamber 140a. Because the water flow impacts the laundry detergent in the detergent dispensing chamber 140a for a relatively short time, insufficient dissolution of the laundry detergent is likely. The filter hole 160a can temporarily retain particles larger than or equal to the pore size of the filter hole 160a on the upper sidewall of the mixing chamber 30d, while particles smaller than the pore size of the filter hole 160a can enter the mixing chamber 30d and then enter the garment processing chamber. During the washing process, the fluid from the detergent dispensing chamber can repeatedly rinse the laundry detergent on the upper sidewall of the mixing chamber 30d, allowing the laundry detergent to dissolve again before entering the mixing chamber 30d. This design results in better dissolution of the laundry detergent, and the laundry detergent particles entering the garment processing chamber are relatively small, improving the cleaning effect.

[0199] In some embodiments, the end of the pressurizing structure 120 forms the outlet end 50Aa of the liquid flow channel 130a. That is, the fluid in the liquid flow channel 130a is ejected directly from the end of the pressurizing structure 120, for example, the end of the narrowed section 22.

[0200] In one embodiment, the outlet end 50Aa of the liquid flow channel 130a can be the outlet end of the second water channel 50A.

[0201] In some embodiments, please refer to Figures 7, 8 and 11, the end of the pressurization structure 120 is connected to a constant diameter section 23 and / or an enlarged diameter section, which forms the outlet end 50Aa of the liquid flow channel 130a.

[0202] For example, the end of the pressurization structure 120 is connected to a constant diameter section 23, which forms the outlet end 50Aa of the liquid flow channel 130a.

[0203] For example, the end of the pressurization structure 120 is connected to an expansion section, which forms the outlet end 50Aa of the liquid flow channel 130a.

[0204] For example, the end of the pressurization structure 120 is connected to a constant diameter section 23 and an expanded diameter section, and either the constant diameter section 23 or the expanded diameter section forms the outlet end 50Aa of the liquid flow channel 130a.

[0205] The constant diameter section 23 refers to the section where the flow area of ​​the fluid remains basically unchanged along the flow direction.

[0206] An expansion section refers to a section where the flow area of ​​the fluid increases along the flow direction.

[0207] In this embodiment, the fluid in the liquid flow channel 130a is directly ejected from the constant diameter section 23 and / or the expanding diameter section into the mixing space 20a. After being accelerated by the pressurization structure 120, the fluid flows through the constant diameter section 23 and / or the expanding diameter section, and the fluid can flow out into the mixing space 20a in a conical divergence at a relatively fast speed.

[0208] In some embodiments, the extension length of the constant diameter section 23 along the liquid flow channel 130a is less than or equal to the extension length of the narrow diameter section 22 along the liquid flow channel 130a. Since the longer the fluid flow path, the more significant its energy loss, limiting the length of the constant diameter section 23 can reduce the loss of impact force after the fluid flows out of the narrow diameter section 22.

[0209] In some embodiments, the extension length of the expanding section along the liquid flow channel 130a is less than or equal to the extension length of the narrowing section 22 along the liquid flow channel 130a. Since the longer the fluid flow path, the more significant its energy loss, limiting the length of the expanding section can reduce the loss of impact force after the fluid flows out of the narrowing section 22.

[0210] In some embodiments, referring to Figures 7, 8, and 11, the outer edge of the helical blade along the helical direction is connected to the inner wall of the liquid flow channel 130a, and the inner edge of the helical blade along the helical direction is spaced apart from the inner wall of the liquid flow channel 130a. That is, there is a gap between the inner edge of the helical blade and the inner wall of the liquid flow channel 130a, so that the inner wall of the liquid flow channel 130a provides connection support for the helical blade.
