[0013] In some embodiments of the present application, the pull rod comprises an end plate fixedly connected to the second end of the pull rod, the end plate being used for being held to push and pull the pull rod and to push and pull the first piston through the pull rod.

[0014] The technical scheme has the following advantages or beneficial effects: for the pull rod arranged on the first piston, the second end of the pull rod is further provided with an end plate, so as to facilitate the user to hold the pull rod, and the first piston is pushed and pulled through the pull rod, so as to realize the axial movement of the first piston in the first piston cavity.

[0015] In some embodiments of the present application, the sleeve further comprises a cylinder cover, the cylinder cover covers the second port of the piston cavity, the cylinder cover is provided with a through hole, the pull rod penetrates through the through hole and extends out of the second port of the piston cavity, and the through hole is used for fixing the pull rod.

[0016] The technical scheme has the following advantages or beneficial effects: by arranging the cylinder cover on the sleeve, the cylinder cover covers the second port of the piston cavity, and the through hole is arranged on the cylinder cover, the pull rod penetrates through the through hole and extends out of the second port of the piston cavity, so as to fix the pull rod and prevent the pull rod from shaking left and right and hindering the axial movement of the first piston in the piston cavity.

[0019] A clothes treatment device applied to the unclogging assembly described above, comprising a machine body for forming a shell of the clothes treatment device; a cylinder body arranged in the machine body, the cylinder body forming a washing cavity for accommodating and treating clothes; a storage box arranged in the delivery box in a detachable manner, the storage box forming a storage cavity for storing washing liquid, a cavity wall of the storage cavity being provided with a liquid outlet, the liquid outlet being used for outputting the washing liquid from the storage cavity; a delivery device arranged in the machine body, the delivery device being provided with a liquid channel, two ends of the liquid channel being respectively provided with a liquid suction port and a liquid discharge port, the liquid discharge port being communicated with the washing cavity; when the storage box is arranged in the machine body, the liquid outlet and the liquid suction port are in butt joint communication; the delivery device successively sucks the washing liquid in the storage cavity through the liquid suction port and the liquid outlet, and successively delivers the sucked washing liquid into the washing cavity through the liquid channel and the liquid discharge port; the liquid suction port can be connected with the first port of the piston cavity, so that the internal space of the piston cavity and the internal space of the liquid channel are in communication.

[0020] The above technical solution has the following advantages or beneficial effects: By setting the storage box as a detachable structure, when the liquid channel is blocked, the storage box can be directly disassembled, and then the unblocking component can be used to unblock the liquid channel. After the storage box is disassembled, the first port of the piston chamber is connected to the liquid extraction port. When the first port of the piston chamber is connected to the liquid extraction port and the first piston moves towards the second outlet of the sleeve, the blockage in the liquid channel is sucked into the piston chamber. The first port of the piston chamber can be connected to the liquid extraction port, and the first piston can move towards the second outlet of the sleeve. The side where the blockage is located at the liquid extraction port is the first side, and the other side is the second side. When the first port of the piston chamber is connected to the suction port, a sealed space is formed between the first piston and the blockage. As the first piston moves towards the second port of the piston chamber, the volume of the sealed space between the blockage and the first piston increases, but the gas content remains almost unchanged. This causes a decrease in the gas pressure within the sealed space. As the first piston moves closer to the second port of the piston chamber, the pressure difference between the first and second sides of the blockage increases. The blockage, under the pressure from the second side, moves towards the suction port and eventually through the suction port and the first port of the piston chamber into the piston chamber. This clears the blockage formed by the washing liquid in the liquid channel, ensuring normal flow and allowing the washing liquid to be transported to the washing chamber. This method draws the blockage in the liquid channel into the piston chamber, clearing the blockage. It eliminates the need for technicians who cannot immediately resolve the problem and incurs no additional costs.

[0021] In some embodiments of this application, the dispenser further includes a liquid extraction tube, the liquid extraction port is disposed inside the liquid extraction tube, and the first port of the piston chamber is sleeved outside the liquid extraction tube so that the first port is connected to the liquid extraction port.

[0022] The above technical solution has the following advantages or beneficial effects: by sleeved the first port of the piston chamber on the outside of the liquid extraction tube, the sealing degree between the first port and the liquid extraction port can be guaranteed to the greatest extent, thereby achieving a better unblocking effect on the blockage in the liquid channel.

[0023] In some embodiments of this application, an annular sealing ring is provided at the first port of the piston cavity, and the sealing ring circumferentially surrounds the inner wall of the first port of the piston cavity.

[0024] The above technical solution has the following advantages or beneficial effects: by setting an annular sealing ring at the first port of the piston chamber, the sealing degree between the first port and the liquid extraction port can be further guaranteed.

[0025] In some embodiments of the present application, the body further comprises a delivery box, the delivery box is internally formed with a receiving cavity, the storage box is detachably arranged in the receiving cavity, the liquid suction port is exposed on the cavity wall of the receiving cavity, and the delivery device is arranged inside the delivery box; when the storage box is arranged in the receiving cavity, the liquid outlet of the storage cavity can be connected to the liquid suction port; when the storage box is detached, the first port of the piston cavity can be connected to the liquid suction port.

[0026] The above technical solution has the following advantages or beneficial effects: the storage box is detachably arranged in the receiving cavity, and the liquid suction port is arranged on the cavity wall of the receiving cavity, so that as long as the storage box is arranged in the receiving cavity, the liquid suction port can be connected to the first port of the piston cavity. The storage box can be more conveniently detached.

[0027] In some embodiments of the present application, the sleeve assembly further comprises a fixing member arranged on the outer wall of the sleeve, and the receiving cavity is further formed with a limiting groove; when the first port of the piston cavity is connected to the liquid suction port, the fixing member can be embedded into the limiting groove, so that the sleeve is fixed in the receiving cavity.

[0028] The above technical solution has the following advantages or beneficial effects: by arranging the fixing member on the outer wall of the sleeve and arranging the limiting groove matched with the fixing member in the receiving cavity, when the first port of the piston cavity is connected to the liquid suction port, the sleeve is fixed in the receiving cavity, without the need for the user to hold it by hand, thereby increasing the convenience of use.

[0053] Many existing laundry treatment devices are equipped with the function of automatically dispensing washing liquid. Although this greatly reduces the user's trouble of measuring and dispensing washing liquid, due to the different types of washing liquid, some of which are prone to caking, causing the liquid channel 41 in the dispenser 4 to be easily blocked, so that the function of automatically dispensing washing liquid cannot be used again.

[0054] When unclogging the blocked liquid channel, the maintenance personnel need to personally visit the laundry treatment device to disassemble and unclog it. The maintenance steps and procedures are complicated, and sometimes the user needs to pay a fee. This greatly reduces the user's experience.

[0055] For ease of description, unless otherwise specified, the orientation expressions of up, down, left, right, front, and back in this paper are based on the state of the laundry treatment device in use, with the direction facing the user as the front side direction and the direction facing away from the user as the back side direction; the vertical direction is the up-down direction, and the horizontal direction is the left-right direction.

[0056] Figure 1 is a structural schematic diagram of a laundry treatment device provided by an embodiment of the present application. The following will be described taking a pulsator washing machine as an example, but it should be noted that the present application is not limited to being applied only in a pulsator washing machine, and the present application can also be applied in a drum washing machine.

[0057] Please refer to Figure 1 In some embodiments, the laundry treatment device provided by the embodiments of the present application can include a machine body 1. The machine body 1 can be configured as an outer shell outside the laundry treatment device. The machine body 1 can generally adopt a rectangular hollow structure.

[0058] It should be noted that in other embodiments, the appearance shape of the machine body 1 can be designed as needed, which is not limited herein. The inside of the machine body 1 can be used to provide a mounting space.

[0059] In some embodiments, a laundry loading / unloading opening 11 can be formed on the upper side wall of the machine body 1. The laundry loading / unloading opening 11 can communicate the internal space of the machine body 1. The laundry can be put into the machine body 1 through the laundry loading / unloading opening 11 for cleaning.

[0060] Please refer toFigure 1 As shown, in some embodiments, a door body 12 can be arranged on the upper side wall of the machine body 1. The door body 12 can be used to open and close the clothes taking and placing opening 11 on the upper side wall of the machine body 1, and thus the space in the machine body 1 can be opened and closed through the door body 12.

[0061] In some embodiments, the door body 12 can be rotatably arranged on the upper side of the machine body 1. The side edge of the door body 12 can be rotatably connected to the upper side wall of the machine body 1, and the side edge of the door body 12 can be rotatably connected to the side edge of the clothes taking and placing opening 11. The door body 12 can be rotated relative to the clothes taking and placing opening 11, and thus the clothes taking and placing opening 11 can be opened and closed.

[0062] In some embodiments, the door body 12 and the machine body 1 can be connected through a hinge. The door body 12 can rotate around the axis of the hinge, and thus the clothes taking and placing opening 11 can be opened and closed.

[0063] Referring to Figure 1 and Figure 2 In some embodiments, a drum body 2 can be arranged in the machine body 1. The drum body 2 can be arranged vertically along the up-down direction of the machine body 1. A washing cavity can be formed in the drum body 2. A dropping opening (not labeled in the figure) can be formed on the upper end surface of the drum body 2. The dropping opening of the drum body 2 can communicate with the inside of the washing cavity. The dropping opening of the drum body 2 can be opposite to the clothes taking and placing opening 11 on the upper side wall of the machine body 1, so that the clothes taking and placing opening 11 can communicate with the inside of the washing cavity.

[0064] In some embodiments, when the door body 12 is rotated to open the clothes taking and placing opening 11, clothes can be sequentially placed into the washing cavity in the drum body 2 through the clothes taking and placing opening 11 of the machine body 1 and the dropping opening at the front end of the drum body 2, and the clothes can be washed, dehydrated, etc. When the door body 12 is rotated to close the clothes taking and placing opening 11, the door body 12 can simultaneously close the clothes taking and placing opening 11 and the washing cavity.

[0065] In some embodiments, a dropping assembly 7 can be arranged in the machine body. The dropping assembly 7 can be arranged above the drum body 2 and below the door body 12. The dropping assembly 7 can store washing liquid and automatically drop the stored liquid into the drum body 2 to wash the clothes.

[0066] Referring to Figures 2 to 6 In some embodiments, the dropping assembly 7 can include a storage box 3. A storage cavity 31 for storing washing liquid can be formed in the storage box 3. A liquid outlet 32 can be arranged on the cavity wall of the storage cavity 31 to facilitate the flow of washing liquid.

[0067] As Figure 3As shown, in some embodiments, two storage boxes 3 can be provided in the dispensing assembly 7 to store different kinds of washing liquid. Of course, in some embodiments, multiple storage boxes 3 can also be provided in the dispensing assembly 7 to store more kinds of washing objects respectively.

[0068] In some embodiments, as shown in Figure 7 , the storage box 3 can be provided with a liquid suction pipe 33, one end of which is a liquid outlet 32. In some embodiments, the liquid suction pipe 33 is in a bent shape, and the other end of the liquid suction pipe 33 is bent towards the bottom of the storage box 3, so as to maximize the emptying of the washing liquid in the storage cavity 31, avoid waste, and save the cost of using the clothes treatment device for the user.

[0069] In some embodiments, the top of the storage box 3 is provided with a storage box dispensing opening 34 for dispensing washing liquid into the dispensing box 3.

[0070] In some embodiments, the liquid outlet 32 is provided at the bottom of the storage cavity 31, so that the washing liquid in the storage cavity 31 can be emptied to the maximum extent, waste is avoided, and the cost of using the clothes treatment device for the user is saved.

[0071] As shown in Figure 8 and Figure 9 , in some embodiments, the dispensing assembly 7 can include a dispenser 4. The dispenser 4 is provided with a liquid channel 41. The liquid channel 41 is used for the washing liquid to pass through and transport the washing liquid stored in the storage cavity 31 to the washing cavity. As shown in Figure 8 the principle diagram of the liquid channel 41, the liquid channel 41 is formed with a liquid suction port 42 and a liquid discharge port 43 on both sides respectively. The liquid discharge port 43 communicates with the washing cavity formed in the barrel 2. The liquid outlet 32 provided on the cavity wall of the storage cavity 31 is in butt joint communication with the liquid suction port 42. When the storage box 3 is arranged in the machine body 1, the liquid outlet 32 provided on the cavity wall of the storage cavity 31 is in butt joint communication with the liquid suction port 42, and the dispenser 4 can successively pass through the liquid outlet 32 and the liquid suction port 42 to suck the washing liquid stored in the storage cavity 31 to the liquid channel 41. Then the washing liquid in the liquid channel 41 is successively transported to the washing cavity through the liquid discharge port 43.

[0072] In some embodiments, when the storage box 3 is detached, the liquid suction port 42 is used for sucking gas or liquid. When the storage box 3 is detached, the gas or liquid in the liquid channel 41 can be sucked through the liquid suction port 42, or the gas or liquid can be injected through the liquid suction port 42. This facilitates the user to replace different external tools or suck or inject other liquids and gases for the liquid suction port 42.

[0073] As shown in Figures 8 to 11In some embodiments, the liquid channel 41 can further comprise a liquid suction branch 411, a liquid discharge branch 412, and a transfer branch 413. The transfer branch 413 can comprise a first port and a second port. A second piston 4133 can be disposed in the transfer branch 413.

[0074] The liquid suction branch 411 can comprise a first port and a second port. The first port 4111 of the liquid suction branch can be in communication with the liquid suction port 42. The second port 4112 of the liquid suction branch can be in communication with the first port 4131 of the transfer branch. A first one-way valve 4113 can be disposed in the liquid suction branch 411 to allow the one-way flow of the washing liquid from the first port 4111 to the second port 4112 of the liquid suction branch.

[0075] The liquid discharge branch 412 can comprise a first port and a second port. The first port 4121 of the liquid discharge branch can be in communication with the liquid discharge port 43. The second port 4122 of the liquid discharge branch can be in communication with the first port 4131 of the transfer branch. A second one-way valve 4123 can be disposed in the liquid discharge branch 412 to allow the one-way flow of the washing liquid from the second port 4122 to the first port 4121 of the liquid discharge branch.

[0076] When the storage box 3 is disposed in the machine body 1, the first port 4111 of the liquid suction branch can be in communication with the liquid outlet port 32, the second piston 4133 can move towards the second port 4132 of the transfer branch, the pressure in the transfer branch 413 can be lowered, and the suction force can be generated. Since the first one-way valve 4113 allows the one-way flow from the first port 4111 to the second port 4112 of the liquid suction branch, the liquid pressure or the gas pressure at the first port of the liquid suction branch does not change, and the second port 4112 of the liquid suction branch is in communication with the transfer branch 413, thereby lowering the gas pressure between the second port 4112 of the liquid suction branch and the first one-way valve 4113, and the first one-way valve 4113 is opened. The washing liquid in the storage cavity 31 is sucked into the liquid suction branch 411 through the liquid suction branch 411 where the first one-way valve 4113 is located, and the washing liquid enters the transfer branch 413 through the first port 4111 of the liquid suction branch, the first one-way valve 4113, the second port 4112 of the liquid suction branch, and the first port 4131 of the transfer branch. In this process, the backflow of the washing liquid in the transfer branch 413 is avoided due to the provision of the first one-way valve 4113.

[0077] When the second piston 4133 moves towards the first port 4131 of the transfer branch, the gas pressure or liquid pressure in the transfer branch 413 increases, the first one-way valve 4113 can only pass through in one direction from the first port 4111 of the suction branch to the second port 4112 of the suction branch, so the gas or liquid in the transfer branch 413 cannot flow back through the first valve. The second valve can only pass through in one direction from the second port 4122 of the discharge branch to the second port 4122 of the discharge branch, and the second valve is opened when the gas pressure or liquid pressure in the transfer branch 413 increases, and the washing liquid is transported to the washing cavity through the first port 4131 of the transfer branch, the second port 4122 of the discharge branch, the second one-way valve 4123, and the first port 4121 of the discharge branch.

The inside of the containing box can be formed with a containing cavity 61. The storage box 3 can be detachably arranged in the containing cavity 61.

[0079] In some embodiments, the suction port 42 is exposed on the cavity wall of the containing cavity 61. When the storage box 3 is arranged in the containing cavity 61, the liquid outlet 32 on the storage box 3 can be directly docked and communicated with the suction port 42. When the storage box 3 is detached, the first port 531 of the piston cavity can be docked and communicated with the suction port 42.

[0086] In some embodiments, the dispensing assembly 7 can comprise a water inlet valve 73. One end of the water inlet valve 73 is connected to a water source, and the other end is in communication with the water pump for supplying water to the water pump.

[0087] In some embodiments, the dispensing assembly 7 can further comprise a water inlet pipe 78 for connecting the water inlet valve 73 and the water pump 76.

[0088] In some embodiments, the washing liquid sequentially passes through the liquid outlet 32, the liquid suction port 42, the liquid discharge port 43, and the liquid outlet pipe 75 into the washing chamber. At the same time, the water pump 76 works, and the water sequentially passes through the water inlet valve 73, the water inlet pipe 78, the water pump 76, the water outlet pipe 79, and the water storage chamber into the mixing chamber 71. The water mixes with the washing liquid, and is discharged from the mixing chamber dispensing port 72 into the washing chamber for treatment of the clothes.

[0089] Please continue to see Figure 8 and Figure 12 In some embodiments, the dispensing assembly 7 can further comprise a cleaning pipe 74. One end of the cleaning pipe 74 is in communication with the water storage chamber. The other end of the cleaning pipe 74 is in communication with the liquid channel 41. When it is necessary to clean the liquid channel 41, the water in the water storage chamber enters the liquid channel 41 through the cleaning pipe 74 to form cleaning liquid. The second piston 4133 reciprocates between the first port 4131 of the transfer branch and the second port 4132 of the transfer branch to input the cleaning liquid in the liquid channel 41 into the washing chamber as the washing liquid, and then discharge it to the clothes treatment device or used for treatment of the clothes.

[0090] Please see Figure 14 and Figure 15 , Figure 14 and Figure 15 shows a dredging assembly 5. Please see Figure 14 — Figure 16 and Figure 18In some embodiments, the unclogging assembly 5 can include a sleeve 51 and a first piston 52. The sleeve 51 is formed with a piston cavity 53 for the axial movement of the first piston 52. The first piston 52 is located in the piston cavity 53, and the piston cavity 53 is formed with a first port and a second port at the axial ends thereof.

[0091] In some embodiments, the first port 531 is used to communicate with the storage cavity 31 of the laundry treating apparatus, so that the liquid or gas in the piston cavity 53 enters the storage cavity 31 for storing the washing liquid. This allows the user to inject gas or liquid into the storage cavity 31 according to his or her own ideas, greatly improving the user experience.

[0092] In some embodiments, the first piston 52 can be cylindrical, and the first piston 52 is formed with a first end and a second end at the two ends thereof. The first end of the first piston 52 is movable in the piston cavity 53, and the second end 4 of the first piston 52 extends out of the second port 532 of the piston cavity. The second end of the first piston 52 can be used to push and pull the first piston 52 to move the piston in the piston cavity 53. For example, the user can hold the second end of the first piston 52 to push and pull the first piston 52.

[0093] In some embodiments, the unclogging assembly 5 can include a pull rod 54. The first end of the pull rod 54 is fixedly connected with the first piston 52 in the piston cavity 53. It should be noted that the fixed connection can be a welded connection or a threaded connection, which is not limited herein as long as the first end of the pull rod 54 can be fixedly connected with the first piston in the piston cavity 53. The pull rod 54 can be used to push and pull the first piston 52 to move the first piston 52 axially in the piston cavity 53. For example, the user can hold the second end of the pull rod 54 to push and pull the first piston 52.

[0094] In some embodiments, the pull rod 54 can further include an end plate 55 fixedly connected with the second end of the pull rod 54. It should be noted that the fixed connection can be a welded connection or a threaded connection, which is not limited herein as long as the end plate 55 can be fixedly connected with the second end of the pull rod 54. By providing the end plate 55 at the second end of the pull rod 54, the user can hold the end plate 55 to push and pull the first piston 52, which makes it easier and more convenient for the first piston 52 to move axially in the piston cavity 53.

[0095] In some embodiments, the sleeve 51 can further comprise a sleeve cover 56. The sleeve cover 56 can be arranged on the second port 532 of the piston cavity. It is to be noted that the connection between the sleeve cover 56 and the second port 532 of the piston cavity can be a screw connection, a welding connection, an embedded connection or any other connection that can fix the sleeve cover 56 to the second port 532 of the piston cavity. Here, no further limitation is made. The sleeve cover 56 is provided with a through hole 561, and the pull rod 54 penetrates the through hole 561 of the sleeve cover 56, and the second end of the pull rod 54 extends out of the second port 532 of the piston cavity. The through hole 561 of the sleeve cover 56 can fix the pull rod 54, so that the pull rod 54 can move in a fixed direction. This can prevent the pull rod 54 from tilting too much relative to the first piston 52, which can cause damage to the first piston 52 or make it difficult for the first piston 52 to move axially along the sleeve 51.

[0096] In some embodiments, the sleeve cover 56 is further provided with at least one air hole 562, which communicates the piston cavity 53 with the outside air. The air hole 562 is used to discharge the gas between the first piston 52 and the sleeve cover 56 in the piston cavity 53 when the first piston 52 moves towards the second port 532 of the piston cavity. This is because if the air tightness between the through hole 561 of the sleeve cover 56 and the pull rod 54 is too good, it can cause the gas between the first piston 52 and the sleeve cover 56 to be continuously compressed and the pressure to be continuously increased when the first piston 52 moves axially towards the second port 532 of the piston cavity, which can make it difficult or impossible for the first piston 52 to move towards the second port 532 of the piston cavity.

[0097] In some embodiments, the diameter of the through hole 561 of the sleeve cover 56 can be greater than the diameter of the pull rod 54, so that the position where the pull rod 54 contacts the through hole 561 can maintain good air permeability. This can avoid the gas between the first piston 52 and the sleeve cover 56 being continuously compressed and the pressure being continuously increased when the first piston 52 moves axially towards the second port 532 of the piston cavity, which can make it difficult or impossible for the first piston 52 to move towards the second port 532 of the piston cavity.

[0098] In some embodiments, a spring can be arranged between the first piston 52 and the first port 531 of the piston cavity in the piston cavity 53. This can help the first piston 52 move from the first port 531 of the piston cavity to the second port 532 of the piston cavity. When the first piston 52 is pushed towards the first port 531 of the piston cavity, the spring is compressed. At this time, the second port 532 of the piston cavity is connected to the suction port 42, and then the pushing of the pull rod 54 is stopped. The elastic force of the spring can then push the first piston 52 to move towards the second port 532 of the piston cavity to extract the blockage. This can completely rely on the spring to push the first piston 52 to move, or can assist the user to move the first piston 52, which greatly improves the user experience.

[0099] In some embodiments, the pull rod 54 is further provided with a first clamping device, which can be extended or retracted in a direction perpendicular to the pull rod 54, and the sleeve 51 is provided with a through hole as a second clamping device, which can accommodate the first clamping device.

[0100] The first piston 52 is pushed towards the first port 531 of the piston cavity, and the spring is compressed until the first clamping device and the second clamping device are connected, the first clamping device is inserted into the through hole as the second clamping device, so as to fix the pull rod 54 and prevent the spring from pushing the first piston 52 to the second port 532 of the piston cavity. At this time, the second port 532 of the piston cavity is connected with the liquid suction port 42, and then the user presses the first clamping device to retract the first clamping device, thereby disconnecting the connection between the first clamping device and the second clamping device, and then the spring pushes the first piston 52 to move towards the second port 532 of the piston cavity to extract the blockage. In this way, the first piston 52 can be completely pushed by the spring or assisted by the user to move, which greatly improves the user experience.

[0101] In some embodiments, the unclogging assembly 5 is used to connect the liquid suction port 42 when the storage box 3 is detached. The liquid suction port 42 can be connected with the first port 531, so that the internal space of the piston cavity 53 communicates with the internal space of the liquid channel 41 to extract the blockage formed in the liquid channel 41. It should be noted that the blockage includes but is not limited to solid formed by solidification of the washing liquid.

[0102] When the storage box 3 is detached, the first port 531 of the piston cavity can be connected with the liquid suction port 42, and the first piston 52 can move towards the second outlet of the sleeve 51. The blockage is located on the first side of the liquid suction port 42, and the other side is the second side. When the first port of the piston cavity 53 is connected with the liquid suction port 42, a closed space is formed between the first piston 52 and the blockage. When the first piston 52 moves in the piston cavity 53 towards the second port 532 of the piston cavity, the volume of the closed space formed between the blockage and the first piston 52 increases, but the gas content remains almost unchanged, resulting in a decrease in the gas pressure of the closed space formed between the blockage and the first piston 52. As the first piston 52 moves closer to the second port 532 of the piston cavity, the pressure difference between the first side and the second side of the blockage increases, and the blockage is pushed by the pressure formed on the second side to move towards the liquid suction port 42. Finally, the blockage moves into the piston cavity 53 through the liquid suction port 42 and the first port 531 of the piston cavity, thereby cleaning the blockage formed by the washing liquid in the liquid channel 41, ensuring the normal flow of the liquid channel 41, and enabling the washing liquid to be delivered to the washing cavity through the liquid channel 41.

[0103] In some embodiments, when the storage box 3 is detached, the first port 531 of the piston cavity is in communication with the suction port 42. When the first port 531 of the piston cavity is in communication with the suction port 42 and the first piston 52 moves towards the second port 532 of the piston cavity, the blockage in the liquid channel 41 is sucked into the piston cavity 53.

[0104] In some embodiments, the dispenser 4 can further comprise a suction tube. The suction port 42 is provided in the suction tube. The suction tube can be exposed to the accommodation cavity 61. The first port of the piston cavity 53 is sleeved on the outside of the suction tube. That is, the diameter of the first port is greater than the diameter of the suction tube, the diameter of the suction port 42 is less than or equal to the diameter of the suction tube, that is, the diameter of the first port is greater than the diameter of the suction port 42. The diameter of the second port 532 of the piston cavity is greater than the diameter of the suction port 42, which can ensure that when the blockage in the liquid channel 41 is removed through the suction port 42, the blockage cannot move at the joint of the second port 532 of the piston cavity and the suction port 42 due to the too small diameter of the second port 532 of the piston cavity, so that the blockage cannot be cleaned out of the liquid channel 41.

[0105] In some embodiments, an annular sealing ring can be provided at the first port 531 of the piston cavity 53. The sealing ring can be circumferentially arranged on the inner wall at the first port 531 of the piston cavity. In this way, the airtightness of the first port 531 of the piston cavity when in communication with the suction port 42 is increased, so that the blockage can be more easily sucked out.

[0106] In some embodiments, the unclogging assembly 5 comprises a plurality of sealing rings with different hole diameters. The outer surface of each sealing ring is provided with external threads, and the inner wall of the first port of the piston cavity 53 is circumferentially provided with internal threads. The external threads on the outer surface of the sealing ring can be screwed with the internal threads provided in the piston cavity 53. This allows the unclogging assembly 5 to replace the sealing ring according to the diameter of the suction port 42 or the suction tube. On the one hand, the unclogging assembly 5 can be adapted to suction ports 42 or suction tubes of various diameters. On the other hand, the joint of the first port 531 of the piston cavity and the suction port 42 or the suction tube is more airtight.

[0107] Please continue to refer to Figure 15 and Figure 16 In some embodiments, by providing a fixing member 57 on the outer wall of the sleeve 51 and a limiting groove 62 in the accommodation cavity 61 that matches the fixing member 57, when the first port 531 of the piston cavity is in communication with the suction port 42, the sleeve 51 is fixed in the accommodation cavity 61, without the user having to hold it by hand, increasing the convenience of use for the user.

[0108] In some embodiments, the fixing member 57 comprises a horizontal plate and a vertical plate, one side of the vertical plate is fixedly connected with the lower part of the sleeve 51, and the other side of the vertical plate is perpendicularly connected with the horizontal plate.
