The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0040] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] The following is for reference. Figure 1 and Figure 2 The spray structure according to an embodiment of the present utility model is described.

[0042] like Figure 1 and Figure 2 As shown, the spray structure according to an embodiment of the present invention includes an inner liner 100, a lower spray section 400, and an upper spray section 500.

[0043] The inner liner 100 has an inner liner cavity 110, within which an upper shelf 200 and a lower shelf 300 are arranged; see reference. Figure 3The lower spray section 400 includes a lower pipe section 410; the upper spray section 500 includes an upper pipe section 510, an upper rotating spray arm 520, and an upper rotating nozzle 530. The lower end of the upper pipe section 510 is connected to the upper end of the lower pipe section 410. The upper rotating spray arm 520 and the upper rotating nozzle 530 are fitted onto the outer wall of the upper pipe section 510. The upper rotating spray arm 520 is located between the upper shelf 200 and the lower shelf 300. The upper rotating spray arm 520 can spray water upwards. The upper rotating nozzle 530 is located above the upper shelf 200. The upper rotating nozzle 530 can spray water to the surrounding areas above the upper shelf 200. The upper rotating nozzle 530 can clean the upper side of the components of the upper shelf 200.

[0044] For example, such as Figure 1 and Figure 2 As shown, the inner liner 100 has an inner liner cavity 110, which can hold water. An upper shelf 200 and a lower shelf 300 are disposed within the inner liner cavity 110, and the upper shelf 200 and lower shelf 300 are relatively fixed within the inner liner cavity 110. (Refer to...) Figure 3 The lower spray section 400 includes a lower pipe section 410, which is capable of carrying water. The upper spray section 500 includes an upper pipe section 510, an upper rotating spray arm 520, and an upper rotating nozzle 530. The lower end of the upper pipe section 510 is connected to the upper end of the lower pipe section 410, forming a pipe structure for water flow. The upper rotating spray arm 520 and the upper rotating nozzle 530 are fitted onto the outer wall of the upper pipe section 510, allowing water from the upper pipe section 510 to flow into the upper rotating spray arm 520 and the upper rotating nozzle 530 respectively. The upper rotating spray arm 520 is located between the upper shelf 200 and the lower shelf 300, and can clean the lower side of the components of the upper shelf 200. The upper rotating nozzle 530 is located above the upper shelf 200, and can clean the upper side of the components of the upper shelf 200.

[0045] In actual work, taking baby bottle cleaning as an example, the lower shelf 300 can hold relatively large parts such as the bottle body, while relatively small parts such as bottle caps and nipples can be placed on the upper shelf 200 for separate cleaning.

[0046] In practical work, refer to Figure 2 , Figure 3After water is injected into the inner chamber 110, the water flows through the lower pipe section 410 and the upper pipe section 510, first entering the lower spray section 400 to clean the components of the lower shelf 300. Then, the water flows into the upper rotating spray arm 520 and the upper rotating nozzle 530. The upper rotating spray arm 520 sprays water to clean the lower side of the components on the upper shelf 200, while the upper rotating nozzle 530 sprays water to clean the upper side of the components on the upper shelf 200. In this way, the components placed on the upper shelf 200 are cleaned from both the top and bottom, ensuring that relatively small components on the upper shelf 200 receive a more thorough cleaning.

[0047] It is conceivable that the upper shelf 200 and the lower shelf 300 can adopt a mesh structure with through holes, or other support structure with sufficient space for water flow, to avoid the upper shelf 200 and the lower shelf 300 themselves blocking the water flow and affecting the cleaning work.

[0048] In some embodiments of this utility model, reference is made to Figure 3 , Figure 4 The upper pipe section 510 has a first side hole 511 on its outer wall and a rotation positioning hole 512 at its upper end. The upper rotating nozzle 530 includes an upper rotating nozzle cavity 531 and a lower rotating nozzle guide sleeve 534. The inner cavity of the upper pipe section 510 communicates with the inner cavity of the rotating nozzle cavity 531 through the first side hole 511. Upper rotating nozzles 532 are distributed on the side wall of the rotating nozzle cavity 531. A rotating nozzle guide shaft 533 is located on the lower side of the top wall of the rotating nozzle cavity 531 and is inserted into the rotation positioning hole 512. The rotating nozzle guide sleeve 534 is engaged with the outer wall of the upper pipe section 510. The upper rotating nozzle 530 can rotate around the upper pipe section 510 and spray water.

[0049] Reference Figure 7 Water is supplied to the rotating nozzle cavity 531 of the upward rotating nozzle 530 by creating a hole 511 on the outer wall of the upper pipe section 510. The rotating nozzle cavity 531 of the upper rotating nozzle 530 is a cavity with a sufficiently large internal space to ensure water flow. Several upper rotating nozzles 532 are evenly distributed on the side wall of the rotating nozzle cavity 531. These upper rotating nozzles 532 are responsible for spraying water at a specific angle and speed for cleaning.

[0050] The rotating nozzle guide sleeve 534 serves to guide and support the rotation of the upper rotating nozzle 530. Simultaneously, a dedicated rotating positioning hole 512 for rotational positioning is provided at the upper end of the upper pipe section 510. This hole, in conjunction with the rotating nozzle guide shaft 533 of the rotating nozzle cavity 531, provides precise positioning support for the installation of the upper rotating nozzle 530. Furthermore, the rotating nozzle guide shaft 533, as a guide shaft structure, ensures the stable rotation of the upper rotating nozzle 530, thereby achieving precise rotation of the upper rotating nozzle 530 and providing a stable water spray washing effect.

[0051] The rotating nozzle guide sleeve 534 of the upper rotating nozzle 530 can be snapped onto the outer wall of the upper pipe section 510, and can also be disassembled, facilitating subsequent installation and maintenance. The above design of the upper rotating nozzle 530 takes into account both functionality and practicality, ensuring the reliable operation of the upper rotating nozzle 530 in water spraying.

[0052] In some embodiments of this utility model, reference is made to Figure 3 , Figure 5 The outer wall of the upper pipe section 510 is provided with, from top to bottom, a first positioning step 513, a second side hole 514, and a second positioning step 515. The upper rotating spray arm 520 includes an upper rotating intermediate cavity 521, with an upper retaining edge 522 and a lower retaining edge 523 respectively provided at its upper and lower ends. The inner cavity of the upper pipe section 510 is connected to the upper rotating intermediate cavity 521 through the second side hole 514. The first positioning step 513 engages with the upper retaining edge 522 of the upper rotating intermediate cavity, and the second positioning step 515 engages with the lower retaining edge 523. The upper rotating spray arm 520 can rotate around the upper pipe section 510 and spray water.

[0053] Reference Figure 7 The first positioning step 513, the second side hole 514, and the second positioning step 515 on the outer wall of the upper pipe section 510 are arranged in sequence and cooperate with each other. The upper rotating intermediate cavity 521 of the upper rotating spray arm 520 is a hollow structure that allows water to pass through. That is, the water inside the upper pipe section 510 is connected to the upper rotating intermediate cavity 521 through the second side hole 514, ensuring that the water can flow smoothly into the upper rotating spray arm 520.

[0054] The upper and lower ends of the upper rotating intermediate cavity 521 are respectively equipped with an upper retaining edge 522 and a lower retaining edge 523. These two retaining edges are designed to precisely align with the first positioning step 513 and the second positioning step 515 of the upper pipe section 510. Specifically, the first positioning step 513 of the upper pipe section precisely engages with the upper retaining edge 522 of the upper rotating intermediate cavity, which is equivalent to the first positioning step 513 of the upper pipe section lifting the upper retaining edge 522 of the upper rotating intermediate cavity of the upper rotating spray arm 520, ensuring that the top position of the upper rotating spray arm 520 is fixed. Similarly, the second positioning step 515 of the upper pipe section also engages with the lower retaining edge 523 of the upper rotating intermediate cavity, which is equivalent to the second positioning step 515 of the upper pipe section lifting the lower retaining edge 523 of the upper rotating intermediate cavity of the upper rotating spray arm 520, thereby ensuring that the bottom position of the upper rotating spray arm 520 is stable and will not loosen and fall down along the upper pipe section 510. This design not only ensures the stability of the upper rotating spray arm 520 during installation and rotation, but also improves the spraying efficiency and reliability of the upper rotating spray arm 520.

[0055] In a further embodiment of this utility model, the upper rotating spray arm 520 is further provided with an upper extending arm 524, which is connected to the outer wall of the upper rotating intermediate cavity 521. The upper extending arm 524 is distributed around the upper rotating intermediate cavity 521 and extends outward. The upper extending arm 524 is provided with vertical water spray holes 525 and oblique water spray holes 526. The vertical water spray holes 525 spray water vertically upward or downward for cleaning. The oblique water spray holes 526 spray oblique water to drive the upper rotating spray arm 520 to rotate. In this way, the upper rotating spray arm 520 can rotate and spray water simultaneously.

[0056] In some embodiments of this invention, a straw nozzle 516 is provided on the outer side of the upper tube section 510. The straw nozzle 516 communicates with the inner cavity of the upper tube section 510, and the straw nozzle 516 can be inserted into the straw of a baby bottle. After the straw is inserted into the straw nozzle 516, water inside the upper tube section 510 can be sprayed out through the straw nozzle 516 to clean the inside of the straw. This provides a better cleaning effect for the straw.

[0057] In some embodiments of this utility model, reference is made to Figure 2 The upper shelf 200 is equipped with a retaining ring frame 210, which has through holes. The upper end of the upper pipe section 510 extends into the retaining ring frame 210, and the upper rotating nozzle 530 is located inside the retaining ring frame 210. The retaining ring frame 210 can separate the upper rotating nozzle 530 from the components on the upper shelf 200. In this way, even when the upper rotating nozzle 530 is rotating, it is prevented from hitting the components on the upper shelf 200, and it is also prevented from being blocked or obstructed from rotating by the components on the upper shelf 200.

[0058] It is conceivable that the inner cavity of the retaining ring frame 210 must be at least larger than the volume of the upper rotating nozzle 530 to ensure that the retaining ring frame 210 itself does not obstruct the operation of the upper rotating nozzle 530. Furthermore, the through hole on the retaining ring frame 210 is smaller than the components on the upper frame 200 to ensure that the components do not enter the retaining ring frame 210.

[0059] In some embodiments of this utility model, the upper pipe section 510 and the lower pipe section 410 are detachably connected.

[0060] In some embodiments of this utility model, the lower spray section 400 is located below the lower shelf 300, and the lower spray section 400 is responsible for cleaning the components on the lower shelf 300. For example, after the bottle is placed upside down on the lower shelf 300, water is injected into the lower spray section 400 through the lower pipe section 410, and then the water flow is split in the lower spray section 400 and sprayed onto the bottle mouth and bottle wall for cleaning.

[0061] In some embodiments of this utility model, reference is made to Figure 3 , Figure 6 The lower shelf 300 has a lower shelf support 310 on its side. The lower shelf support 310 is used to support the components on the lower shelf 300, such as the bottle, so that they can be placed vertically.

[0062] In some embodiments of this utility model, a lower fixed spray frame 420 and a lower rotating spray arm 430 are provided on the lower pipe section 410. The lower fixed spray frame 420 is fixed and can spray water, while the lower rotating spray arm 430 can rotate and spray water simultaneously. This can improve the cleaning effect on the components placed on the lower shelf 300.

[0063] In a further embodiment of this utility model, a first side hole 413 is provided on the side wall of the lower pipe section 410. A lower fixed spray frame 420 is fixedly installed on the lower pipe section 410. The lower fixed spray frame 420 includes a main water pipe 421, a water distribution pipe 422, and a nozzle 423. The nozzle 423 is connected to the main water pipe 421 through the water distribution pipe 422. Water inside the lower pipe section 410 can enter the main water pipe 421 of the lower fixed spray frame 420 through the first side hole 413, and then the water in the main water pipe 421 is distributed to the water distribution pipes 422 and sprayed out through the nozzles 423 for cleaning.

[0064] In a further embodiment of this utility model, a retractable lower pipe section snap-on pressing part 417 is provided on the lower pipe section 410, and a lower pipe section fixing snap 4171 is provided on the lower pipe section snap-on pressing part 417, which can lock the lower fixed spray frame 420. A lower pipe section snap-on spring 4172 is provided inside the lower pipe section snap-on pressing part 417, and the two ends of the lower pipe section snap-on spring 4172 respectively press against the lower pipe section snap-on pressing part 417 and the lower pipe section 410, causing the lower pipe section snap-on pressing part 417 to pop outward.

[0065] When the lower pipe section clip pressing part 417 is pressed down, the lower pipe section clip pressing part 417 retracts, causing the lower pipe section fixing clip 4171 to move and disengage from the lower fixed spray frame 420, thus allowing the lower fixed spray frame 420 to be removed. When the lower pipe section clip pressing part 417 is released, the lower pipe section clip pressing part 417 pops out under the spring force of the lower pipe section clip spring 4172, causing the lower pipe section fixing clip 4171 to move and lock the lower fixed spray frame 420, thus fixing the lower fixed spray frame 420.

[0066] In a further embodiment of this utility model, referring to Figure 6 , Figure 8 The lower pipe section 410 has a second side hole 414 on its side wall. A first positioning step 415 and a second positioning step 416 are respectively provided on the upper and lower sides of the second side hole 414. A lower rotating spray arm 430 is fitted onto the lower pipe section 410. The lower rotating spray arm 430 includes a lower rotating intermediate cavity 431, and an upper retaining edge 432 and a lower retaining edge 433 are provided on the upper and lower sides of the lower rotating intermediate cavity 431.

[0067] After the lower rotating spray arm 430 is fitted onto the lower pipe section 410, water inside the lower pipe section 410 can pass through the second side hole 414 of the lower pipe section and enter the lower rotating intermediate cavity 431 of the lower rotating spray arm 430. The first positioning step 415 of the lower pipe section 410 abuts against the upper retaining edge 432 of the lower rotating intermediate cavity of the lower rotating spray arm 430, and the second positioning step 416 of the lower pipe section abuts against the lower retaining edge 433 of the lower rotating intermediate cavity, ensuring that the lower rotating spray arm 430 can rotate stably in the lower pipe section 410.

[0068] In a further embodiment of this utility model, a lower extension arm 434 is provided on the outer side of the lower rotating intermediate cavity 431. The lower extension arm 434 has vertical water spray holes 435 and oblique water spray holes 436 distributed on it. The vertical water spray holes 435 can spray vertical water streams for cleaning. The oblique water spray holes 436 can spray oblique water streams to drive the lower rotating spray arm 430 to rotate.

[0069] In a further embodiment of this utility model, the lower pipe section 410 includes an upper lower pipe section first component 411 and a lower lower pipe section second component 412. The lower pipe section first component 411 and the lower pipe section second component 412 are detachably connected. The lower pipe section first side hole 413, the lower pipe section snap-on pressing part 417, and the lower pipe section upper insertion plate 418 are located on the lower pipe section first component 411. The lower pipe section second side hole 414, the lower pipe section first positioning step 415, and the lower pipe section second positioning step 416 are located on the lower pipe section second component 412.

[0070] The baby bottle cleaning device according to a second aspect embodiment of the present invention includes a spray structure according to the first aspect embodiment of the present invention described above. (Refer to...) Figure 1 , Figure 2 , Figure 3 The bottle body is placed upside down on the lower shelf 300, while the bottle cap and nipple are placed on the upper shelf 200. The lower spray section 400 is located below the lower shelf 300 and can spray water upwards. A washing pump 600 and a water pump 160 are installed on the lower side of the inner tank 100. The inner cavity of the washing pump 600 is connected to the lower side of the lower pipe section 410 through the pump inlet 610. The washing pump 600 has a pump drain outlet 620 for draining water, and a drain valve is installed on the pump drain outlet 620. The water pump 160 is connected to an external water source and can deliver water into the inner tank cavity 110. That is, the inner tank 100 is connected to an external water source through the water pump 160. The pump inlet 610 can draw water into the inner tank 100 and then inject water into the upper and lower pipe sections. The pump drain outlet 620, in conjunction with the drain valve, can drain water after the cleaning process is complete.

[0071] In actual operation, the drain valve of the pump drain outlet 620 is closed, and the water pump 160 is turned on to pump water into the inner liner cavity 110.

[0072] After water is injected into the inner chamber 110, the washing pump 600 starts and draws water from the inner chamber 110. The water is then output through the pump inlet 610, forming a water flow that passes through the lower pipe section 410 and the upper pipe section 510, entering the upper rotating spray arm 520 and the upper rotating nozzle 530 respectively. The lower spray section 400 cleans the components on the lower shelf 300, the upper rotating spray arm 520 cleans the underside of the components on the upper shelf 200, and the upper rotating nozzle 530 cleans the upper side of the components on the upper shelf 200. In this way, the components placed on the upper shelf 200 are cleaned from both the top and bottom, ensuring that relatively small components on the upper shelf 200 receive a more thorough cleaning.

[0073] After cleaning is completed, the washing pump 600 stops supplying water to the lower pipe section 410 and the upper pipe section 510, and opens the drain valve on the pump drain port 620. In this way, the water in the inner tank cavity 110 is discharged outward through the drain port 620 of the washing pump 600 under the action of gravity.

[0074] The baby bottle cleaning device according to the present invention improves the space utilization of the baby bottle cleaning device by adopting the above-mentioned spray structure, which facilitates the miniaturization and compact design of the baby bottle cleaning device, and can also improve the cleaning efficiency of the baby bottle cleaning device and enhance the user experience.

[0075] In some embodiments of this utility model, the washing pump 600 has a water inlet 610, a drain outlet 620, a return outlet 630, and a hot air outlet 640. The water inlet 610 is connected to the lower pipe section 410. The return outlet 630 is connected to the inner tank cavity 110. The drain outlet 620 is capable of draining water outwards. The hot air outlet 640 is capable of connecting to a hot air pipe 801 to inject hot air.

[0076] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 The inner liner 100 of the inner liner cavity 110 has an opening covered by a top cover 700. A top cover sensing magnet 710 is provided on the lower side of the top cover 700, and a Hall switch 120 is provided on the upper side of the outer wall of the inner liner cavity 110. The Hall switch 120 can sense the top cover sensing magnet 710. Only when the top cover 700 is tightly closed on the inner liner 100 can the Hall switch 120 sense the magnetic attraction of the sensing magnet 710 and be triggered. Then the baby bottle cleaning device of this utility model can continue to work. This design can prevent the baby bottle cleaning device from being activated when the top cover 700 is not properly closed, which would cause water leakage.

[0077] In a further embodiment of this invention, the top cover sensing magnets 710 are positioned on the left and right sides of the lower side of the top cover 700. Hall effect switches 120 are positioned on the left and right sides of the outer wall of the inner cavity 110. This design effectively requires both sides of the top cover 700 to be tightly sealed before the bottle cleaning device of this invention can be activated, thus preventing leakage.

[0078] In some embodiments of this utility model, reference is made to Figure 9 The inner wall of the inner liner cavity 110 has a bottom slope 130, and a concave central cavity 140 is provided below the bottom slope 130. The bottom slope 130 is inclined from the upper side of the outer side of the inner liner cavity 110 to the lower side of the bottom slope 130. A lower heater 141 and a pump return port 630 of the washing pump 600 are provided below the central cavity 140. The pump return port 630 is connected to the inner cavity of the washing pump 600. A filter screen plate 150 is covered on the upper side of the central cavity 140. A filter screen plate drain port 151 is opened on the filter screen plate 150. The filter screen plate drain port 151 is located above the pump return port 630. A removable filter element 152 is covered on the pump return port 630.

[0079] The concentrating chamber 140 is located below the bottom slope 130, allowing water on the bottom slope 130 to flow into the concentrating chamber 140. Water in the inner tank cavity 110 can be discharged through the pump return port 630 or drawn into the lower spray section 400 by the washing pump 600. That is, water in the inner tank cavity 110 can be discharged through the pump return port 630 and the pump drain port 620, or sequentially pass through the pump return port 630, the washing pump 600, the pump water inlet 610, and the lower spray section 400 and the upper spray section 500 to form an internal circulation of washing water.

[0080] The lower heater 141 is responsible for heating the central chamber 140, causing the water in the inner tank 100 to boil and generate steam, which serves as a steam sterilization function.

[0081] In some embodiments of this utility model, reference is made to Figure 9 , Figure 10 An input chamber 800 is provided on the rear side of the inner liner cavity 110. The input chamber 800 has an input chamber outlet 810 on the front side that communicates with the inner liner cavity 110. The input chamber 800 is provided with a hot air pipe 801 that communicates with the lower pipe section 410. The input chamber 800 is provided with a water pump outlet pipe 162 that communicates with the water pump 160. The water pump 160 is connected to an external water source. Water can flow through the water pump 160 and the input chamber outlet 810 in sequence into the inner liner cavity 110.

[0082] The input chamber 800 has a built-in heater 820 and a fan 830. The heater 820 can generate heat to form a hot airflow. Part of the hot airflow can enter the lower pipe section 410 through the input chamber 800 and the hot air pipe 801, and another part of the hot airflow can enter the inner liner cavity 110 through the input chamber 800 and the input chamber outlet 810.

[0083] When cleaning the baby bottle, first place the bottle in the inner chamber 110, then the water pump 160 draws water and injects it into the inlet chamber 800 through the water pump outlet pipe 162. The water in the inlet chamber 800 then flows into the inner chamber 110 through the inlet chamber outlet 810. Once there is enough water in the inner chamber 110, the lower spray section 400 and the upper spray section 500 can draw water from the inner chamber 110 to rinse the bottle and clean it thoroughly.

[0084] After the bottles are cleaned and the water in the inner chamber 110 is drained, the drying process can begin. The heater 820 in the input chamber 800 generates heat, and the fan 830 blows air to form a hot airflow. Part of this hot airflow passes through the input chamber outlet 810 and is blown into the inner chamber 110, drying the bottles, the lower spray section 400, the upper spray section 500, and the inner wall of the inner chamber 110. The remaining hot airflow passes through the hot air pipe 801 and enters the lower spray section 400 and the upper spray section 500, drying their interiors.

[0085] In a further embodiment of this utility model, a spray frame air guide pipe 424 is provided on the lower fixed spray frame 420, and a spray frame air guide pipe horn inlet 425 is provided at the input end of the spray frame air guide pipe 424, with the spray frame air guide pipe horn inlet 425 facing the input chamber outlet 810. Spray frame air guide pipe outlets 426 are distributed on the spray frame air guide pipe 424. When hot air is blown into the inner cavity 110 through the input chamber outlet 810, a portion of the hot air can be blown into the spray frame air guide pipe horn inlet 425, then enter the spray frame air guide pipe 424 and be ejected from the spray frame air guide pipe outlets 426. This design facilitates a more uniform distribution of hot air within the inner cavity 110 for hot air drying.

[0086] In a further embodiment of this utility model, referring to Figure 9 A baffle plate 811 is installed on the upper cover of the input chamber outlet 810. The baffle plate 811 has a horizontal rotating shaft on its upper side, which is connected to the wall of the input chamber outlet 810. A baffle plate limiting part is provided on the wall of the input chamber outlet 810, which can abut against the rear side wall of the baffle plate 811, allowing the baffle plate 811 to flip forward. When the baffle plate 811 is in a vertical state, it can block the input chamber outlet 810; when the baffle plate 811 is in a flipped state, it can open the input chamber outlet 810. This one-way opening and closing design of the baffle plate 811 ensures that water or hot air in the input chamber 800 can force its way through the baffle plate 811 and enter the inner liner cavity 110, while water or airflow in the inner liner cavity 110 cannot flow back into the input chamber 800.

[0087] In some specific embodiments of this utility model, the water pump 160 takes in water through the water pump inlet pipe 161 and exits water through the water pump outlet pipe 162.

[0088] In some embodiments of this utility model, a water tank 170 is provided next to the inner tank 100, and a water tank cover 171 is fitted onto the water tank 170. A water pump 160 is connected to the water tank 170 through a water pump inlet pipe 161. That is, the water pump 160 can draw water from the water tank 170.

[0089] In some embodiments of this utility model, reference is made to Figure 10 , Figure 11The present invention also includes a three-way valve 900, which has a first opening 910 on its upper side and a second opening 920 and a third opening 930 on its lower side. The input chamber 800 is connected to the first opening 910 via a pressure balancing pipe 802. The inner chamber 110 has a drain outlet 620 for the washing pump 600 on its lower side. The drain valve of the drain outlet 620 is connected to the second opening 920 via a drain pipe front section 621. The third opening 930 is externally connected to a drain pipe rear section 622. The air pressure in the input chamber 800 can be balanced between the input chamber 800 and the three-way valve 900 by passing through the air pressure balance pipe 802, the first opening 910 of the three-way valve, and the three-way valve 900 in sequence. The water flow in the inner liner 110 can be discharged by passing through the pump drain outlet 620, the front section of the drain pipe 621, the three-way valve 900, and the rear section of the drain pipe 622 in sequence.

[0090] The three-way valve 900 serves to balance air pressure during drainage, preventing backflow. This three-way valve 900 has three ports: an upper first opening 910, a lower second opening 920, and a third opening 930. To achieve balanced air pressure regulation, an air pressure balancing pipe 802 connects the input chamber 800 to the first opening 910 of the three-way valve. At the lower side of the inner liner cavity 110, a washing pump 600 is installed. Specifically, the pump drain port 620 of the washing pump 600 is connected to the second opening 920 of the three-way valve via the front section 621 of the drain pipe, while the third opening 930 connects to the rear section 622 of the external drain pipe, forming a complete drainage pipe structure.

[0091] During actual drainage, water in the inner chamber 110 passes sequentially through the pump drain port 620, the front section of the drain pipe 621, and then through the inner cavity of the three-way valve 900, finally exiting the device through the rear section of the drain pipe 622. Simultaneously, gas inside the input chamber 800 passes sequentially through the pressure balance pipe 802 and the first opening 910 of the three-way valve, ultimately connecting with the three-way valve 900. This ensures that the air pressure between the input chamber 800 and the three-way valve 900 is balanced. Thus, the three-way valve 900 dynamically maintains consistent air pressure between the outside and the inner chamber 110, preventing backflow of external wastewater into the inner chamber 110 and preventing water from the inner chamber from failing to drain properly due to factors such as a loose valve plate on the washing pump 600, which could cause the washing pump 600 to fail to start.

[0092] In a further embodiment of this invention, a one-way valve plate 940 is fitted over the first opening 910 of the three-way valve. The one-way valve plate 940 allows fluid from the pressure balancing pipe 802 to enter the inner cavity of the three-way valve 900, while preventing fluid from entering the pressure balancing pipe 802 from the three-way valve 900. This prevents water from flowing back into the pressure balancing pipe 802 from the three-way valve 900.
