[0063] Please see Figure 3As shown, in some embodiments, the garment processing device may include a water tank assembly 2. The water tank assembly 2 can be used in a dryer. The water tank assembly 2 forms the water tank of the dryer, which is used to collect condensate generated during the drying process and requires periodic cleaning by the user. The water tank assembly 2 includes a receiving box 21 and a pull-out box 22. The pull-out box 22 is movable and can be pulled out and moved within the receiving box 21. The pull-out box 22 can store condensate, and by pulling and moving the pull-out box 22, it can be opened or closed, thereby enabling periodic cleaning of the collected condensate.

[0064] It should be noted that in some other embodiments, the garment processing device may include a water tank assembly 2. The water tank assembly 2 can be disposed in the garment processing device for storing garment processing agents. For example, the water tank assembly 2 can be disposed in a washing machine, forming a detergent dispenser assembly for the washing machine. The receiving box 21 of the water tank assembly 2 can be used as a water inlet box, and the pull-out box 22 of the water tank assembly 2 can be used as a washing box. The washing box can be pulled out from within the water inlet box. The washing box can be used to store detergent. The water inlet box has a water inlet, allowing water to enter the water inlet box and then into the washing box. The water flow can mix with the detergent, so that the mixed solution enters the casing 1 from the outlets of the detergent box and the water inlet box, thereby filling the casing 1 with detergent. This facilitates the use of the water tank assembly 2 to add detergent to the washing tub of the washing machine in measured increments.

[0065] Please see Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the receiving box 21 has a receiving space 211. A push-pull opening 210 is provided at one end of the receiving box 21. The push-pull opening 210 is located on one side of the receiving space 211 and is connected to the receiving space 211. The pull-out box 22 is movably pulled out and fitted into the receiving space 211 to open or close. Therefore, when it is necessary to pour out the condensate in the pull-out box 22, the pull-out box 22 can be pulled out of the receiving space 211 from the pull-out opening, thereby pouring out the condensate in the pull-out box 22.

[0066] Please see Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the top wall of the receiving box 21 has a water inlet 212. Condensate generated during the drying process can enter the receiving box 21 through the water inlet 212. A drain outlet 213 is provided on the bottom wall of the receiving box 21. The drain outlet 213 can communicate with the receiving space 211 inside the receiving box 21. After the condensate enters the receiving box 21 through the water inlet 212, the condensate inside the receiving box 21 can be discharged outside the casing 1 through the drain outlet 213.

[0067] Please see Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the bottom wall of the receiving box 21 is recessed with a water passage groove 214. A drain outlet 213 is formed on the bottom wall of the water passage groove 214. After condensate enters the receiving box 21 through the water inlet 212, the condensate in the receiving box 21 can flow into the water passage groove 214 and be discharged from the casing 1 through the drain outlet 213 on the water passage groove 214.

[0068] In some embodiments, the drain outlet 213 is located at the end of the water channel 214 furthest from the push-pull opening 210. The height of the end of the water channel 214 near the push-pull opening 210 is higher than the height of the end of the water channel 214 furthest from the push-pull opening 210. Therefore, when condensate flows into the water channel 214, all the condensate in the water channel 214 can flow out through the drain outlet 213, improving the drainage efficiency of the water channel 214.

[0069] Please see Figure 2 and Figure 3 As shown, in some embodiments, the pull-out box 22 is provided with a water storage chamber (not shown in the figure). The water storage chamber is used to store condensate generated during the drying process of the clothing processing equipment. The top wall of the pull-out box 22 is provided with a water inlet 221, and a water inlet 212 can be connected to the water inlet 221. Condensate can enter the water storage chamber through the water inlet 212 and the water inlet 221, so that the water storage chamber can collect the condensate generated during the drying process.

[0070] In some embodiments, a water outlet 222 is also provided on the side wall of the pull-out box 22. The water outlet 222 may be provided on the top wall of the pull-out box 22. The water outlet 222 may be arranged at a distance from the water inlet 221. The water outlet 222 may be connected to the receiving space 211 of the receiving box 21. When the condensate in the water storage chamber is full, the condensate in the water storage chamber may overflow into the receiving space 211 of the receiving box 21 through the water outlet 222, and be discharged out of the casing 1 through the drain outlet 213 on the bottom wall of the receiving box 21.

[0071] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the garment handling device may include a roller assembly 3. The roller assembly 3 may be disposed between the receiving box 21 and the pull-out box 22. The roller assembly 3 can be used to reduce the friction between the receiving box 21 and the pull-out box 22, thereby allowing the pull-out box 22 to be pulled out of the receiving box 21 more smoothly, thus improving the convenience of pulling the pull-out box 22 out of the receiving space 211.

[0072] In some embodiments, a groove 4 is installed on the inner wall of the receiving box 21. The roller assembly 3 can be installed in the groove 4. One side of the roller assembly 3 can protrude from the groove 4. When the pull-out box 22 is pulled out of the receiving box 21, the side of the roller assembly 3 protruding from the groove 4 can abut against the outer wall of the pull-out box 22. Thus, the roller assembly 3 enables rolling friction between the pull-out box 22 and the receiving box 21 when the pull-out box 22 is pulled out of the receiving box 21, thereby making the pull-out box 22 easier to pull out of the receiving box 21 and improving the convenience of pulling out the pull-out box 22 in the receiving space 211.

[0073] It should be noted that in some embodiments, the mounting groove 4 can be formed on the outer wall of the pull-out box 22, and the roller assembly 3 can be installed in the mounting groove 4. One side of the roller assembly 3 can protrude from the mounting groove 4. When the pull-out box 22 is pulled out of the receiving box 21, the side of the roller assembly 3 protruding from the mounting groove 4 can abut against the inner wall of the receiving box 21. Thus, the roller assembly 3 enables rolling friction between the pull-out box 22 and the receiving box 21 when the pull-out box 22 is pulled out of the receiving box 21, thereby making the pull-out box 22 easier to pull out of the receiving box 21 and improving the convenience of pulling out the pull-out box 22 in the receiving space 211.

[0074] It should be noted that, in some embodiments, a mounting slot 4 may be provided. A mounting slot 4 may be formed on the inner wall of the receiving box 21 or on the outer wall of the pull-out box 22.

[0075] It should also be noted that in some embodiments, multiple mounting slots 4 may be provided. These multiple mounting slots 4 may be respectively formed on the inner wall of the receiving box 21 and the outer wall of the pull-out box 22. Multiple roller assemblies 3 may be provided. These multiple roller assemblies 3 can be respectively configured to correspond to multiple mounting slots 4.

[0076] Therefore, when the pull-out box 22 is pulled out of the receiving box 21, the roller assembly 3 installed on the outer wall of the pull-out box 22 can abut against the inner wall of the receiving box 21 and roll along the inner wall of the receiving box 21; the roller assembly 3 installed on the inner wall of the receiving box 21 can abut against the outer wall of the pull-out box 22 and roll along the outer wall of the pull-out box 22, so that rolling friction is formed between the pull-out box 22 and the receiving box 21, thereby making the pull-out box 22 more smoothly pulled out of the receiving box 21, thereby improving the convenience of pulling out the pull-out box 22 in the receiving space 211.

[0077] Please see Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, a mounting groove may be provided on the inner bottom wall of the receiving box 21, and the mounting groove 4 on the inner bottom wall of the receiving box 21 is a first mounting groove 4a. The roller assembly 3 installed in the first mounting groove 4a is a first roller assembly 3a. The first roller assembly 3a is installed downward in the first mounting groove 4a, and the top of the first roller assembly 3a can protrude from the first mounting groove 4a. When the pull-out box 22 is pulled out in the receiving box 21, the top of the first roller assembly 3a can abut against the outer bottom wall of the pull-out box 22. Thus, the first roller assembly 3a enables the pull-out box 22 to be pulled out of the receiving box 21 more smoothly, thereby improving the convenience of pulling out the pull-out box 22 in the receiving space 211.

[0078] Please see Figure 6 and Figure 7 As shown, in some embodiments, two first mounting slots 4a may be provided. The two first mounting slots 4a may be arranged at intervals on the inner bottom wall of the receiving box 21. Two sets of first roller assemblies 3a may be provided. The two sets of first roller assemblies 3a may be installed one-to-one with the two first mounting slots 4a. The two first mounting slots 4a may be arranged at intervals along the vertical pulling direction of the pull-out box 22. Therefore, by using the two first mounting slots 4a arranged at intervals along the vertical pulling direction of the pull-out box 22, the pull-out box 22 maintains a horizontal posture during the pushing and pulling process within the receiving box 21, preventing unevenness or twisting, thus making the pull-out box 22 operate more smoothly and stably.

[0079] It should be noted that in some other embodiments, the first mounting slot 4a may also have three or more. The first roller assembly 3a may have three or more sets. Multiple first roller assemblies 3a may be installed one-to-one with multiple first mounting slots 4a.

[0080] It should also be noted that in some other embodiments, the two first mounting slots 4a can also be arranged at intervals along the pulling direction of the pull-out box 22 so that the pull-out box 22 will not have a jerky feeling during the pulling process, and the movement trajectory of the pull-out box 22 will be more stable.

[0081] Please see Figure 5 , Figure 13 and Figure 14As shown, in some embodiments, a mounting groove may be provided on the inner top wall of the receiving box 21, and the mounting groove 4 on the inner top wall of the receiving box 21 is a second mounting groove 4b. The roller assembly 3 installed in the second mounting groove 4b is a second roller assembly 3b. The bottom of the second roller assembly 3b can protrude from the second mounting groove 4b. When the pull-out box 22 is pulled out of the receiving box 21, the bottom of the second roller assembly 3b can abut against the outer top wall of the pull-out box 22. Thus, the second roller assembly 3b can make rolling friction between the pull-out box 22 and the receiving box 21 when the pull-out box 22 is pulled out of the receiving box 21, thereby making the pull-out box 22 more smoothly pulled out of the receiving box 21, and thus improving the convenience of pulling out the pull-out box 22 in the receiving space 211.

[0082] In some embodiments, two second mounting slots 4b may be provided. The two second mounting slots 4b may be arranged at intervals on the inner top wall of the receiving box 21. Two sets of second roller assemblies 3b may be provided. The two sets of second roller assemblies 3b may be installed one-to-one with the two second mounting slots 4b. The two second mounting slots 4b may be arranged at intervals along the pulling direction of the pull-out box 22. Therefore, by using the two second mounting slots 4b arranged at intervals along the pulling direction of the pull-out box 22, the pull-out box 22 will not experience any jerking during the pulling process, making the movement trajectory of the pull-out box 22 smoother.

[0083] It should be noted that in some other embodiments, the second mounting slot 4b may also have three or more. The second roller assembly 3b may have three or more sets. Multiple second roller assemblies 3b may be installed in a one-to-one correspondence with multiple second mounting slots 4b.

[0084] It should also be noted that in some other embodiments, the two second mounting slots 4b can also be arranged at intervals along the pulling direction of the vertical pull-out box 22 so that the pull-out box 22 maintains a horizontal posture during the pulling process and does not have one end higher than the other or twisted, so that the pull-out box 22 runs more smoothly.

[0085] Please see Figure 3 , Figure 15 , Figure 16 and Figure 17As shown, in some embodiments, the outer bottom wall of the pull-out box 22 may be provided with a mounting groove, and the mounting groove 4 provided on the outer bottom wall of the pull-out box 22 is a third mounting groove 4c. The roller assembly 3 installed in the third mounting groove 4c is a third roller assembly 3c. The bottom of the third roller assembly 3c can protrude from the third mounting groove 4c. When the pull-out box 22 is pulled out in the receiving box 21, the bottom of the third roller assembly 3c can abut against the inner bottom wall of the receiving box 21. Thus, the third roller assembly 3c enables rolling friction between the pull-out box 22 and the receiving box 21 when the pull-out box 22 is pulled out in the receiving box 21, thereby making the pull-out box 22 easier to pull out from the receiving box 21 and improving the convenience of pulling out the pull-out box 22 in the receiving space 211.

[0086] Two third mounting slots 4c can be provided. The two third mounting slots 4c can be arranged alternately on the outer bottom wall of the pull-out box 22. Two sets of third roller assemblies 3c5 can be provided. The two sets of third roller assemblies 3c5 can be installed one-to-one with the two third mounting slots 4c. The two third mounting slots 4c can be arranged alternately along the vertical pulling direction of the pull-out box 22. Therefore, by using the two third mounting slots 4c arranged alternately along the vertical pulling direction of the pull-out box 22, the pull-out box 22 maintains a horizontal posture during the pulling process, preventing unevenness or twisting, thus making the pull-out box 22 operate more smoothly and stably.

[0087] It should be noted that in some other embodiments, there may be three or more third mounting slots 4c. There may be three or more sets of third roller assemblies 3c5. Multiple third roller assemblies 3c5 can be installed one-to-one with multiple third mounting slots 4c.

[0088] It should also be noted that in some other embodiments, the two third mounting slots 4c can also be arranged at intervals along the pulling direction of the pull-out box 22, so that the pull-out box 22 will not have a jerky feeling during the pulling process, and the movement trajectory of the pull-out box 22 will be more stable.

[0089] Please see Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the mounting groove 4 can be located at the end of the receiving box 21 near the push-pull opening 210, so that the pull-out box 22 can abut against the roller assembly 3 as soon as it is pushed into the receiving space 211, so that the pull-out box 22 and the receiving box 21 can achieve rolling friction, thereby avoiding sliding friction with greater friction between the pull-out box 22 and the receiving box 21, and thus improving the smoothness of the pull-out box 22 in the receiving box 21.

[0090] In some embodiments, the mounting groove 4 may also be located at the end of the pull-out box 22 that first enters the push-pull opening 210. Thus, during the installation of the pull-out box 22, the roller assembly 3 can roll against the inner wall of the receiving box 21 throughout the entire process, thereby avoiding sliding friction with high friction between the pull-out box 22 and the receiving box 21, and thus preventing jerking during the push-pull operation of the pull-out box 22, ensuring the stability of the pull-out box 22 within the receiving box 21.

[0091] Specifically, in this embodiment, the first mounting groove 4a can be located at the end of the receiving box 21 near the push-pull opening 210, so that the pull-out box 22 can abut against the first roller assembly 3a as soon as it is pushed into the receiving space 211. The third mounting groove 4c can be located at the end of the pull-out box 22 that first enters the push-pull opening 210. Thus, during the installation of the pull-out box 22, the third roller assembly 3c can roll against the inner wall of the receiving box 21 throughout the entire process. Therefore, by using the cooperation of the first and third rolling assemblies, the stability of the pull-out box 22 during the pulling process can be provided with double protection.

[0092] Please see Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the roller assembly 3 may include a mounting bracket 31 and a roller. The roller is rotatably mounted on the mounting bracket 31. The mounting bracket 31 may be mounted within a mounting groove 4, allowing the roller to be rotatably mounted within the mounting groove 4.

[0093] Specifically, the first roller assembly 3a, the second roller assembly 3b, and the third roller assembly 3c all include structurally identical mounting brackets 31 and rollers, differing only in their mounting positions. Specifically, the mounting bracket 31 of the first roller assembly 3a can be installed within the first mounting groove 4a. The mounting bracket 31 of the second roller assembly 3b can be installed within the second mounting groove 4b. The mounting bracket 31 of the third roller assembly 3c can be installed within the third mounting groove 4c.

[0094] Please see Figure 8 and Figure 9 As shown, in some embodiments, the mounting bracket 31 has a rotating groove, and the roller has a rotating shaft at its center. The roller can be rotatably mounted in the rotating groove via the rotating shaft, and one side of the roller protrudes from the rotating groove. When the pull-out box 22 is pulled out of the receiving space 211, the side of the roller protruding from the rotating groove can abut against the outer wall of the pull-out box 22, thereby creating rolling friction between the pull-out box 22 and the receiving box 21. This reduces the friction between the pull-out box 22 and the receiving box 21 during the pulling process, thus improving the ease of pulling out the pull-out box 22 and the receiving box 21.

[0095] For example, when the first roller assembly 3a is installed downwards in the first mounting groove 4a, the mounting bracket 31 of the first roller assembly 3a is fixed downwards in the first mounting groove 4a, and the top of the roller of the first roller assembly 3a protrudes from the top side opening of the first mounting groove 4a and abuts against the outer bottom wall of the pull-out box 22. When the pull-out box 22 is pulled out in the receiving space 211, the top of the roller of the first roller assembly 3a can protrude from the rotation groove of the mounting bracket 31 on the first roller assembly 3a and abut against the outer bottom wall of the pull-out box 22.

[0096] For example, when the second roller assembly 3b is installed upwards in the second mounting groove 4b, the mounting bracket 31 of the second roller assembly 3b is fixed upwards in the second mounting groove 4b, and the bottom of the roller of the second roller assembly 3b protrudes from the bottom side slot of the second mounting groove 4b and abuts against the outer top wall of the pull-out box 22. When the pull-out box 22 is pulled out in the receiving space 211, the bottom of the roller of the second roller assembly 3b can protrude from the rotation groove of the mounting bracket 31 on the second roller assembly 3b and abut against the outer top wall of the pull-out box 22.

[0097] For example, when the third roller assembly 3c is installed upwards in the third mounting groove 4c, the mounting bracket 31 of the third roller assembly 3c is fixed upwards in the third mounting groove 4c, and the bottom of the roller of the third roller assembly 3c protrudes from the bottom side groove of the third mounting groove 4c and abuts against the outer bottom wall of the receiving box 21. When the pull-out box 22 is pulled out in the receiving space 211, the bottom part of the roller of the third roller assembly 3c can protrude from the rotation groove of the mounting bracket 31 on the third roller assembly 3c and abut against the outer bottom wall of the receiving box 21.

[0098] In some embodiments, the mounting bracket 31 may be elongated. The mounting bracket 31 extends along the pull-out direction of the pull-out box 22. Two rotating grooves are provided on the mounting bracket 31. The two rotating grooves may include a first rotating groove 311 and a second rotating groove 312. The first rotating groove 311 and the second rotating groove 312 are spaced apart along the length of the mounting bracket 31. The first rotating groove 311 and the second rotating groove 312 are also spaced apart along the pull-out direction of the pull-out box 22. Two rollers may be provided. The two rollers may include a first roller 32 and a second roller 33. The first roller 32 and the second roller 33 are spaced apart along the pull-out direction of the pull-out box 22. The first roller 32 and the second roller 33 can be respectively configured to correspond one-to-one with the first rotating groove 311 and the second rotating groove 312. Therefore, by using two rollers spaced apart along the pull-out direction of the pull-out box 22, each roller can bear a portion of the total weight, thereby improving the load-bearing capacity of the mounting bracket 31. Simultaneously, the two rollers improve the stability of the pull-out box 22 during the pull-out process.

[0099] It should be noted that in some other embodiments, the mounting bracket 31 may have one, three, or more rotating slots. The rollers may have one, three, or more. The number of rollers may correspond to the number of rotating slots. Multiple rollers can be configured to correspond one-to-one with multiple rotating slots.

[0100] Please see Figure 10 and Figure 11 As shown, in some embodiments, the mounting groove 4 has a protruding locking protrusion on its side wall in the pulling direction of the pull-out box 22. The locking protrusion protrudes towards the center of the mounting groove 4. The mounting bracket 31 has a locking portion at its longitudinal end. When the mounting bracket 31 is installed in the mounting groove 4, the locking portion engages with the locking protrusion. Thus, by utilizing the corresponding engagement of the locking protrusion and the locking portion, a stable connection between the mounting bracket 31 and the mounting groove 4 is achieved.

[0101] It should be noted that in some other embodiments, the latching protrusion may also be provided on other side walls of the mounting groove 4. The latching portion may also be provided at the end of the mounting bracket in the width direction or other directions.

[0102] In some embodiments, two latching protrusions may be provided. The two latching protrusions include a first latching protrusion 41 and a second latching protrusion 42. The first latching protrusion 41 and the second latching protrusion 42 are respectively protruding from opposite side walls of the mounting groove 4 in the pulling direction of the pull-out box 22. The first latching protrusion 41 can protrude towards the center of the mounting groove 4. The second latching protrusion 42 can protrude towards the center of the mounting groove 4. Two engaging portions are provided, which may include a first engaging portion 313 and a second engaging portion 314. The first engaging portion 313 and the second engaging portion 314 are respectively provided at opposite ends of the mounting bracket 31 in the length direction. When the mounting bracket 31 is installed in the mounting groove 4, the first engaging portion 313 engages with the first latching protrusion 41, and the second engaging portion 314 engages with the second latching protrusion 42. Therefore, by using the first snap-fit ​​part 313 and the first snap-fit ​​protrusion 41 to snap-fit, and the second snap-fit ​​part 314 and the second snap-fit ​​protrusion 42 to snap-fit, the two ends of the mounting bracket 31 in the length direction can be fixed in the mounting groove 4, thereby improving the stability of the mounting bracket 31 in the mounting groove 4.

[0103] It should be noted that in some other embodiments, there may be one, three, or three latching protrusions. There may be one, three, or more latching portions. The number of latching protrusions may correspond to the number of latching portions. Multiple latching protrusions can be configured to correspond one-to-one with multiple latching portions.

[0104] In some embodiments, the first engaging portion 313 may be provided with a first engaging groove 3131. When the first engaging portion 313 engages with the first engaging protrusion 41, the first engaging protrusion 41 can extend into and engage within the first engaging groove 3131, thereby achieving engagement between the first engaging protrusion 41 and the first engaging portion 313. Thus, by utilizing the engagement between the first engaging protrusion 41 and the first engaging groove 3131, the first engaging protrusion 41 can be stably engaged with the first engaging portion 313.

[0105] In some embodiments, the second engaging portion 314 may be provided with a second engaging groove 3141. When the second engaging portion 314 engages with the second engaging protrusion 42, the second engaging protrusion 42 can extend into and engage within the second engaging groove 3141, thereby achieving engagement between the second engaging protrusion 42 and the second engaging portion 314. Thus, by utilizing the engagement between the second engaging protrusion 42 and the second engaging groove 3141, the second engaging protrusion 42 can be stably engaged with the second engaging portion 314.

[0106] Please see Figure 8 , Figure 10 and Figure 11 As shown, in some embodiments, the mounting bracket 31 may have an outer wall surface 317 and an inner wall surface 318 disposed opposite to each other. When the mounting bracket 31 is installed in the mounting groove 4, the inner wall surface 318 of the mounting bracket 31 is installed in the mounting groove 4, the outer wall surface 317 of the mounting bracket 31 is exposed in the mounting groove 4, and one side of the roller can protrude from the outer wall surface 317 of the mounting bracket 31.

[0107] For example, when the first roller assembly 3a is installed downward in the first mounting groove 4a, the mounting bracket 31 of the first roller assembly 3a is fixed downward in the first mounting groove 4a, and the top of the roller of the first roller assembly 3a protrudes from the outer wall surface 317 of the mounting bracket 31 of the first roller assembly 3a and protrudes from the top side groove of the first mounting groove 4a, so that the top of the roller of the first roller assembly 3a abuts against the outer bottom wall of the pull-out box 22.

[0108] For example, when the second roller assembly 3b is installed downward in the second mounting groove 4b, the mounting bracket 31 of the second roller assembly 3b is fixed downward in the second mounting groove 4b, and the top of the roller of the second roller assembly 3b protrudes from the outer wall surface 317 of the mounting bracket 31 of the second roller assembly 3b and protrudes from the top side groove of the second mounting groove 4b, so that the top of the roller of the second roller assembly 3b abuts against the outer top wall of the pull-out box 22.

[0109] For example, when the third roller assembly 3c is installed downward in the third mounting groove 4c, the mounting bracket 31 of the third roller assembly 3c is fixed downward in the third mounting groove 4c, and the top of the roller of the third roller assembly 3c protrudes from the outer wall surface 317 of the mounting bracket 31 of the third roller assembly 3c and protrudes from the top side groove of the third mounting groove 4c, so that the top of the roller of the third roller assembly 3c abuts against the outer lower wall of the receiving box 21.

[0110] In some embodiments, the mounting bracket 31 is provided with a first notch area 315. The first notch area 315 may be provided between the first snap-fit ​​portion 313 and the first rotating groove 311. One end of the first snap-fit ​​portion 313 is connected to the outer wall surface 317 of the mounting bracket 31, and the other end of the first snap-fit ​​portion 313 is a first free end, which extends toward the inner wall surface 318 of the mounting bracket 31. Thus, when the mounting bracket 31 is installed in the mounting groove 4a, the first free end can deform toward the first notch area 315 to achieve snap-fit ​​fixation between the first snap-fit ​​protrusion 41 and the first snap-fit ​​portion 313, thereby improving the stability of the mounting bracket 31 and the first mounting groove 4a.

[0111] In some embodiments, the mounting bracket 31 is provided with a second notch area 316. The second notch area 316 may be located between the second snap-fit ​​portion 314 and the second rotating groove 312. One end of the second snap-fit ​​portion 314 is connected to the outer wall surface 317 of the mounting bracket 31, and the other end of the second snap-fit ​​portion 314 is a second free end, which extends toward the inner wall surface 318 of the mounting bracket 31. Thus, when the mounting bracket 31 is installed in the mounting groove 4, the second free end can deform toward the second notch area 316 to achieve snap-fit ​​fixation between the second snap protrusion 42 and the second snap-fit ​​portion 314, thereby improving the stability of the mounting bracket 31 and the mounting groove 4.

[0112] Please see Figure 12 As shown, in some embodiments, a first inclined surface 3132 is provided on the side of the first free end away from the first notch area 315. The first inclined surface 3132 is inclined towards the first notch area 315 in the direction from the outer wall surface 317 to the inner wall surface 318. A first mounting surface 411 is provided on the first latching protrusion 41. The first mounting surface 411 is inclined towards the center of the mounting groove 4 in the direction from the outer wall surface 317 to the inner wall surface 318. Therefore, when installing the mounting bracket 31, only the first free end needs to be aligned with the first latching protrusion 41 and vertical pressure applied. Utilizing the cooperation of the first mounting surface 411 and the first inclined surface 3132, the first latching protrusion 41 can be quickly latched and fixed with the first latching portion 313, improving the efficiency of mounting bracket 31 installation and making the installation of the mounting bracket 31 more convenient.

[0113] Please see Figure 13As shown, in some embodiments, a second inclined surface 3142 is provided on the side of the second free end away from the second notch area 316. The second inclined surface 3142 is inclined towards the second notch area 316 in the direction from the outer wall surface 317 to the inner wall surface 318. A second mounting surface 421 is provided on the second latching protrusion 42. The second mounting surface 421 is inclined towards the center of the mounting groove 4 in the direction from the outer wall surface 317 to the inner wall surface 318. Therefore, when installing the mounting bracket 31, only the second free end needs to be aligned with the second latching protrusion 42 and vertical pressure applied. Utilizing the cooperation of the second mounting surface 421 and the second inclined surface 3142, the second latching protrusion 42 can be quickly latched and fixed with the second latching portion 314, improving the efficiency of mounting bracket 31 installation and making the installation of the mounting bracket 31 more convenient.

[0114] Please see Figure 12 and Figure 13 As shown, in some embodiments, the first rotating groove 311 penetrates the outer wall surface 317 and the inner wall surface 318 of the mounting bracket 31. The first rotating groove 311 forms a first outer opening 3111 at the outer wall surface 317, a first inner opening 3112 at the inner wall surface 318, and a first side opening 3113 is formed on the side of the first rotating groove 311 facing the first notch area 315. The first side opening 3113 is connected to the first notch area 315 and is also connected to the first inner opening 3112. Thus, when the first roller 32 is installed in the first rotating groove 311, the first roller 32 can extend into it from the first side opening 3113, and the first rotating groove 311 can undergo elastic deformation relative to the two side walls, allowing the first roller 32 to extend between the two opposite side walls of the first rotating groove 311, thereby enabling the first roller 32 to be rotatably installed in the first rotating groove 311.

[0115] In some embodiments, the second rotating groove 312 penetrates the outer wall surface 317 and the inner wall surface 318 of the mounting bracket 31. The second rotating groove 312 forms a second outer opening 3121 at the outer wall surface 317, a second inner opening 3122 at the inner wall surface 318, and a second side opening 3123 on the side of the second rotating groove 312 facing the second notch area 316. The second side opening 3123 communicates with the second notch area 316 and with the second inner opening 3122. Therefore, when the second roller 33 is installed in the second rotating groove 312, the second roller 33 can extend into the second side opening 3123, and the second rotating groove 312 can elastically deform relative to its two side walls, allowing the second roller 33 to extend between the two opposite side walls of the second rotating groove 312, thereby enabling the second roller 33 to be rotatably installed in the second rotating groove 312.

[0116] Please see Figure 5 , Figure 14 and Figure 15 As shown, in some embodiments, the receiving box 21 may include a box body 215 and a cover 216. The box body 215 has a receiving space 211. The top of the box body 215 has an opening. A sliding opening 210 is provided on the front side of the box body 215. The cover 216 covers the top opening of the box body 215. A water inlet 212 is provided on the cover 216. The cover 216 can serve as the top wall of the receiving box 21.

[0117] Please see Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, in some embodiments, a protrusion 2151 is provided on the outer surface of the peripheral sidewall of the box body 215. An extension portion 2161 extends from the outer periphery of the cover 216 along the side facing the box body 215. A slot 2162 may be provided on the extension portion 2161. When the cover 216 moves toward the box body 215, the extension portion 2161 can move toward the box body 215 and press the protrusion 2151, so that the protrusion 2151 can be engaged in the slot 2162, so that the cover 216 covers the top opening of the box body 215.

[0118] It should be noted that in some other embodiments, the cover 216 and the box 215 can also be connected by bolts or other means.

[0119] In some embodiments, multiple protrusions 2151 may be provided. The multiple protrusions 2151 may be arranged at intervals. The multiple protrusions 2151 may surround the periphery of the outer surface of the housing 215. Multiple extensions 2161 may be provided. The multiple extensions 2161 may be circumferentially spaced around the periphery of the cover 216. The multiple extensions 2161 and the multiple protrusions 2151 may be arranged in a one-to-one correspondence. Thus, by utilizing the cooperation of multiple protrusions 2151 and multiple extensions 2161, the stability of the connection between the cover 216 and the housing 215 is improved.

[0120] Specifically, the first mounting groove 4a can be formed on the inner bottom wall of the box 215. The second mounting groove 4b can be formed on the inner top wall of the cover 216.
