DETAILED DESCRIPTION

[0018] The following describes embodiments of the present invention in detail.

The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0022] Reference below Figure 1 and Figure 2 A spray structure according to an embodiment of the present invention is described.

[0023] like Figure 1 and Figure 2 As shown, the spray structure according to an embodiment of the present invention includes an inner container 100 , a lower spray part 400 and an upper spray part 500 .

[0024] The inner container 100 has an inner container cavity 110, and an upper shelf 200 and a lower shelf 300 are arranged in the inner container cavity 110; Figure 3 The lower spray part 400 includes a lower pipe section 410; the upper spray part 500 includes an upper pipe section 510, an upper rotating spray arm 520 and an upper rotating spray head 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 spray head 530 are mounted on 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 upward. The upper rotating spray head 530 is located above the upper shelf 200. The upper rotating spray head 530 can spray water to the upper position of the surrounding upper shelf 200. The upper rotating spray arm 520 can clean the lower side of the components of the upper shelf 200, and the upper rotating spray head 530 can clean the upper side of the components of the upper shelf 200.

[0025] For example, Figure 1 and Figure 2As shown, the inner liner 100 has an inner liner cavity 110, and the inner liner cavity 110 can be filled with water. An upper shelf 200 and a lower shelf 300 are set in the inner liner cavity 110, and the upper shelf 200 and the lower shelf 300 are relatively fixed in the inner liner cavity 110. Figure 3 The lower spray section 400 includes a lower pipe section 410, through which water can flow. The upper spray section 500 includes an upper pipe section 510, an upper rotating spray arm 520, and an upper rotating spray head 530. The lower end of the upper pipe section 510 is connected to the upper end of the lower pipe section 410, connecting the upper and lower pipe sections 510 to form a single pipe structure for water flow. The upper rotating spray arm 520 and the upper rotating spray head 530 are mounted on the outer wall of the upper pipe section 510, allowing water in the upper pipe section 510 to flow into the upper rotating spray arm 520 and the upper rotating spray head 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 part of the upper shelf 200. The upper rotating spray head 530 is located above the upper shelf 200 and can clean the upper part of the upper shelf 200.

[0026] During actual work, taking the cleaning of feeding bottles as an example, the lower shelf 300 can be used to place components such as relatively large bottle bodies, while components such as relatively small bottle caps and nipples can be placed on the upper shelf 200 for separate cleaning.

[0027] In actual work, refer to Figure 2 、 Figure 3 After water is injected into the inner chamber 110 and passes through the lower pipe section 410 and the upper pipe section 510, the water first enters the lower spray section 400 and cleans the components on the lower shelf 300. The water then enters the upper rotating spray arm 520 and the upper rotating spray head 530, respectively. 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 spray head 530 sprays water to clean the upper side of the components on the upper shelf 200. In this way, both the upper and lower sides of the components placed on the upper shelf 200 can be cleaned by the spray water, ensuring that the relatively small components on the upper shelf 200 receive a more thorough cleaning effect.

[0028] It is conceivable that the upper rack 200 and the lower rack 300 can adopt a grid structure with through holes, or other support structures with sufficient space for water to pass through, so as to avoid the upper rack 200 and the lower rack 300 themselves blocking the water flow and affecting the cleaning work.

[0029] In some embodiments of the present invention, reference Figure 3 、 Figure 4The outer wall of the upper pipe section 510 is provided with an upper pipe section first side hole 511, and the upper end of the upper pipe section 510 is provided with an upper pipe section rotation positioning hole 512. The upper rotating sprinkler 530 includes an upper rotating sprinkler chamber 531 and a lower rotating sprinkler guide sleeve 534. The inner cavity of the upper pipe section 510 is connected to the inner cavity of the rotating sprinkler chamber 531 through the upper pipe section first side hole 511. Upper rotating nozzles 532 are distributed on the side walls of the rotating sprinkler chamber 531. A rotating sprinkler guide shaft 533 is provided on the lower side of the top wall of the rotating sprinkler chamber 531. The rotating sprinkler guide shaft is inserted into the upper pipe section rotation positioning hole 512. The rotating sprinkler guide sleeve 534 is snapped onto the outer wall of the upper pipe section 510. The upper rotating sprinkler 530 can rotate around the upper pipe section 510 and spray water.

[0030] Reference Figure 7 Water is supplied to the rotating nozzle chamber 531 of the upper rotating nozzle 530 through a first side hole 511 formed on the outer wall of the upper tube section 510. The rotating nozzle chamber 531 of the upper rotating nozzle 530 is a cavity with a sufficient internal space to ensure water flow. Several upper rotating nozzles 532 are evenly distributed on the side walls of the rotating nozzle chamber 531. These upper rotating nozzles 532 are responsible for spraying water at a specific angle and speed for cleaning.

[0031] The rotating nozzle guide sleeve 534 guides and supports the upper rotating nozzle 530 during rotation. A dedicated upper tube section rotation positioning hole 512 is provided at the upper end of the upper tube section 510 for rotational positioning. This hole cooperates with the rotating nozzle guide shaft 533 of the rotating nozzle chamber 531 to provide precise positioning support for the upper rotating nozzle 530 during installation. 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 spraying effect.

[0032] The upper rotating sprinkler head 530 has a rotating nozzle guide sleeve 534 that can be snapped onto the outer wall of the upper pipe section 510 and can be removed to facilitate subsequent installation and maintenance. The above design of the upper rotating sprinkler head 530 takes into account both functionality and practicality, ensuring reliable operation of the upper rotating sprinkler head 530 in its water spraying operation.

[0033] In some embodiments of the present invention, reference Figure 3 、 Figure 5The outer wall of the upper pipe section 510 is provided with a first upper pipe section positioning step 513, a second upper pipe section side hole 514, and a second upper pipe section positioning step 515 from top to bottom. The upper rotating spray arm 520 includes an upper rotating intermediate chamber 521, with an upper rotating intermediate chamber upper clamping edge 522 and an upper rotating intermediate chamber lower clamping edge 523 provided at the upper and lower ends of the upper rotating intermediate chamber 521. The inner cavity of the upper pipe section 510 is connected to the upper rotating intermediate chamber 521 through the second upper pipe section side hole 514. The first upper pipe section positioning step 513 clamps the upper rotating intermediate chamber upper clamping edge 522, and the second upper pipe section positioning step 515 clamps the upper rotating intermediate chamber lower clamping edge 523. The upper rotating spray arm 520 can rotate around the upper pipe section 510 and spray water.

[0034] Reference Figure 7 On the outer wall of the upper pipe section 510, the upper pipe section first positioning step 513, the upper pipe section second side hole 514, and the upper pipe section second positioning step 515 are arranged in sequence and cooperate with each other. The upper rotating middle cavity 521 of the upper rotating spray arm 520 is a hollow structure that allows water to flow. That is, water in the lumen of the upper pipe section 510 is connected to the upper rotating middle cavity 521 through the upper pipe section second side hole 514, ensuring smooth flow of water into the upper rotating spray arm 520.

[0035] The upper and lower ends of the upper rotating intermediate cavity 521 are respectively equipped with an upper rotating intermediate cavity upper clamping edge 522 and an upper rotating intermediate cavity lower clamping edge 523. These two clamping edges are designed to precisely dock with the upper tube section first positioning step 513 and the upper tube section second positioning step 515 of the upper tube section 510. Specifically, the upper tube section first positioning step 513 accurately clamps the upper rotating intermediate cavity upper clamping edge 522, which is equivalent to the upper tube section first positioning step 513 lifting the upper rotating intermediate cavity upper clamping edge 522 of the upper rotating spray arm 520 upward, ensuring that the top position of the upper rotating spray arm 520 is fixed; and the upper tube section second positioning step 515 also clamps the upper rotating intermediate cavity lower clamping edge 523, which is equivalent to the upper tube section second positioning step 515 lifting the upper rotating intermediate cavity lower clamping edge 523 of the upper rotating spray arm 520 upward, 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 tube 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.

[0036] In a further embodiment of the present invention, the upper rotating spray arm 520 is further provided with an upper extension arm 524, which is connected to the outer wall of the upper rotating intermediate chamber 521. The upper extension arm 524 is distributed around the upper rotating intermediate chamber 521 and extends outward. The upper extension arm 524 is provided with upper extension arm vertical spray holes 525 and upper extension arm oblique spray holes 526. The upper extension arm vertical spray holes 525 spray water vertically upward or downward to perform cleaning operations. The upper extension arm oblique spray holes 526 spray oblique water streams, which drive the upper rotating spray arm 520 to rotate. In this way, the upper rotating spray arm 520 can spray water while rotating.

[0037] In some embodiments of the present invention, a straw nozzle 516 is disposed on the exterior of the upper tube section 510. The nozzle 516 communicates with the interior of the upper tube section 510 and is adapted to receive a straw from a feeding bottle. Once the straw is attached to the nozzle 516, water within the upper tube section 510 is ejected through the nozzle 516 to clean the interior of the straw, resulting in a more effective cleaning effect.

[0038] In some embodiments of the present invention, reference Figure 2 The upper frame 200 is provided with a retaining ring frame 210 having through holes. The upper end of the upper pipe section 510 extends into the retaining ring frame 210. The upper rotating spray head 530 is located within the retaining ring frame 210. The retaining ring frame 210 can separate the upper rotating spray head 530 from the components on the upper frame 200. In this way, even when the upper rotating spray head 530 rotates, it can prevent the upper rotating spray head 530 from hitting the components on the upper frame 200, and also prevent the components on the upper frame 200 from blocking the upper rotating spray head 530 or preventing the upper rotating spray head 530 from rotating.

[0039] It is conceivable that the inner cavity of the retaining ring frame 210 is at least larger than the volume of the upper rotating spray head 530 to ensure that the retaining ring frame 210 itself does not block the operation of the upper rotating spray head 530. In addition, the through hole of 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.

[0040] In some embodiments of the present invention, the upper pipe section 510 and the lower pipe section 410 are detachably connected.

[0041] In some embodiments of the present invention, the lower spray section 400 is located below the lower shelf 300 and is responsible for cleaning the components on the lower shelf 300. For example, after a bottle is placed upside down on the lower shelf 300, the lower spray section 400 injects water through the lower pipe section 410. The water then flows through the lower spray section 400 and sprays the bottle mouth and bottle wall for cleaning.

[0042] In some embodiments of the present invention, reference Figure 3 、 Figure 6A lower stand 310 is provided on the side of the lower shelf 300. The lower stand 310 is used to support the components on the lower shelf 300, such as the bottle body, so that it can be placed vertically.

[0043] In some embodiments of the present invention, the lower pipe section 410 is provided with a lower fixed spray rack 420 and a lower rotating spray arm 430. The lower fixed spray rack 420 is stationary and can spray water, while the lower rotating spray arm 430 can spray water while rotating. This can improve the cleaning effect of the components placed on the lower shelf 300.

[0044] In a further embodiment of the present invention, a lower pipe section first side hole 413 is provided on the side wall of the lower pipe section 410. A lower fixed spray rack 420 is fixedly mounted on the lower pipe section 410. The lower fixed spray rack 420 includes a spray rack main water pipe 421, a spray rack water distribution pipe 422, and a spray rack nozzle 423. The spray rack nozzle 423 is connected to the spray rack main water pipe 421 via the spray rack water distribution pipe 422. Water within the inner cavity of the lower pipe section 410 can enter the spray rack main water pipe 421 of the lower fixed spray rack 420 through the lower pipe section first side hole 413. The water in the spray rack main water pipe 421 is then distributed to the spray rack water distribution pipes 422 at various locations and sprayed out through the spray rack nozzles 423 for cleaning.

[0045] In a further embodiment of the present invention, a retractable lower tube segment buckle pressing portion 417 is provided on the lower tube segment buckle pressing portion 417. A lower tube segment fixing buckle 4171 is provided on the lower tube segment buckle pressing portion 417. The lower tube segment fixing buckle 4171 can clamp the lower fixed spray rack 420. A lower tube segment buckle spring 4172 is provided within the lower tube segment buckle pressing portion 417. The two ends of the lower tube segment buckle spring 4172 respectively press against the lower tube segment buckle pressing portion 417 and the lower tube segment 410, causing the lower tube segment buckle pressing portion 417 to pop outward.

[0046] When the lower pipe section buckle pressing portion 417 is pressed, the lower pipe section buckle pressing portion 417 retracts, causing the lower pipe section fixing buckle 4171 to move and disengage from the lower fixed spray rack 420, thereby allowing the lower fixed spray rack 420 to be removed. When the lower pipe section buckle pressing portion 417 is released, the lower pipe section buckle pressing portion 417 is ejected under the spring force of the lower pipe section buckle spring 4172, causing the lower pipe section fixing buckle 4171 to move and engage the lower fixed spray rack 420, thereby securing the lower fixed spray rack 420.

[0047] In a further embodiment of the present invention, referring to Figure 6 、 Figure 8The sidewall of the lower tube section 410 is provided with a second lower tube section side hole 414. A first lower tube section positioning step 415 and a second lower tube section positioning step 416 are respectively provided on the upper and lower sides of the second lower tube section side hole 414. The lower rotating spray arm 430 is sleeved onto the lower tube section 410. The lower rotating spray arm 430 includes a lower rotating intermediate chamber 431. The lower rotating intermediate chamber 431 is provided with an upper lower rotating intermediate chamber clamping edge 432 and a lower lower rotating intermediate chamber clamping edge 433 on the upper and lower sides.

[0048] After the lower rotating spray arm 430 is mounted on the lower pipe section 410, water in the inner cavity of the lower pipe section 410 can pass through the second side hole 414 of the lower pipe section and enter the lower rotating middle cavity 431 of the lower rotating spray arm 430. The first lower pipe section positioning step 415 of the lower pipe section 410 abuts against the upper clamping edge 432 of the lower rotating middle cavity of the lower rotating spray arm 430, and the second lower pipe section positioning step 416 abuts against the lower clamping edge 433 of the lower rotating middle cavity, ensuring that the lower rotating spray arm 430 can rotate stably on the lower pipe section 410.

[0049] In a further embodiment of the present invention, a lower extension arm 434 is disposed outside the lower rotating intermediate chamber 431. Lower extension arm 434 is provided with vertical spray holes 435 and oblique spray holes 436. The vertical spray holes 435 spray a vertical stream of water for cleaning, while the oblique spray holes 436 spray an oblique stream of water, driving the rotation of the lower rotating spray arm 430.

[0050] In a further embodiment of the present invention, the lower tube section 410 includes an upper first lower tube section assembly 411 and a lower second lower tube section assembly 412. The first and second lower tube section assemblies 411 and 412 are detachably connected. A first lower tube section side hole 413, a lower tube section buckle pressing portion 417, and an upper lower tube section plug-in plate 418 are located on the first lower tube section assembly 411. A second lower tube section side hole 414, a first lower tube section positioning step 415, and a second lower tube section positioning step 416 are located on the second lower tube section assembly 412.

[0051] The bottle cleaning device according to the second embodiment of the present invention comprises the spray structure according to the first embodiment of the present invention. Figure 1 、 Figure 2 、 Figure 3The bottle body of the baby bottle is placed upside down on the lower shelf 300, and the bottle cap and nipple of the baby bottle are placed on the upper shelf 200. The lower spray part 400 is located on the lower side of the lower shelf 300. The lower spray part 400 can spray water upward. A washing pump 600 and a water pump 160 are provided on the lower side of the inner liner 100. The inner cavity of the washing pump 600 is connected to the lower side of the lower pipe section 410 through the pump water inlet 610. The washing pump 600 has a pump outlet 620 for draining water. The pump outlet 620 is provided with a drain valve. The water pump 160 is connected to an external water source and can transport water into the inner liner cavity 110. That is, the inner liner 100 is connected to an external water source through the water pump 160. The pump water inlet 610 can draw water from the inner liner 100 and then inject water into the upper and lower pipe sections. The pump outlet 620 cooperates with the drain valve to control the water to the outside after the complete cleaning work.

[0052] During actual operation, the drain valve of the pump drain port 620 is closed, and the water pump 160 is turned on to pump water into the inner tank cavity 110 .

[0053] After water is injected into the inner chamber 110, the washing pump 600 starts and sucks in the water from the inner chamber 110. The water is then output through the pump water inlet 610 to form a water flow that can pass through the lower pipe section 410 and the upper pipe section 510 and enter the upper rotating spray arm 520 and the upper rotating nozzle 530, respectively. The lower spray section 400 is then responsible for cleaning the components on the lower shelf 300, the upper rotating spray arm 520 sprays water to clean the lower side of the components on the upper shelf 200, and the upper rotating nozzle 530 sprays water to clean the upper side of the components on the upper shelf 200. In this way, both the upper and lower sides of the components placed on the upper shelf 200 can be cleaned by spraying water, ensuring that the relatively small components on the upper shelf 200 can receive a more adequate cleaning effect.

[0054] 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.

[0055] According to the embodiment of the present invention, the baby bottle cleaning device adopts the above-mentioned spray structure, thereby improving the space utilization rate of the baby bottle cleaning device, facilitating the miniaturization and compactness of the baby bottle cleaning device, and improving the cleaning efficiency of the baby bottle cleaning device, thereby enhancing the user experience.

[0056] In some embodiments of the present invention, the washing pump 600 includes a water inlet 610, a water outlet 620, a return port 630, and a hot air outlet 640. The water inlet 610 communicates with the lower pipe section 410. The return port 630 communicates with the inner chamber 110. The water outlet 620 can drain water. The hot air outlet 640 can connect to the hot air pipe 801 to inject hot air.

[0057] In some embodiments of the present invention, reference Figure 1 、 Figure 2 The upper opening of the inner liner 100 is covered with a top cover 700. A top cover induction magnet 710 is disposed on the underside of the top cover 700. A Hall switch 120 is disposed on the upper side of the outer wall of the inner liner 110. The Hall switch 120 can sense the magnetic attraction of the top cover induction 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 induction magnet 710 and be triggered. Only then can the feeding bottle cleaning device of the present invention continue to operate. This design prevents the feeding bottle cleaning device of the present invention from being activated without the top cover 700 properly closed, which could result in leakage.

[0058] In a further embodiment of the present invention, top cover sensing magnets 710 are located on the left and right sides of the underside of top cover 700. Hall switches 120 are located on the left and right sides of the outer wall of inner chamber 110. This design requires that both sides of top cover 700 be tightly closed before the bottle cleaning device of the present invention can be activated, thus preventing water leakage.

[0059] In some embodiments of the present invention, reference Figure 9 The bottom wall of the inner tank cavity 110 is provided with a bottom slope 130, and a concave central cavity 140 is provided on the lower side of the bottom slope 130. The bottom slope 130 is inclined along the upper side of the outer side of the inner tank cavity 110 toward 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 on the lower side of the central cavity 140. The pump return port 630 is connected to the inner cavity of the washing pump 600. The upper side of the central cavity 140 is covered with a filter plate 150, and a filter plate drain port 151 is opened on the filter plate 150. The filter plate drain port 151 is located above the pump return port 630. The pump return port 630 is covered with a detachable filter element 152.

[0060] The centralizing chamber 140 is located below the bottom slope 130, so that the water on the bottom slope 130 can be concentrated and flow into the centralizing chamber 140. The water in the inner tank cavity 110 can be discharged through the pump return port 630 or drawn into the lower spray part 400 by the washing pump 600. That is, the water in the inner tank cavity 110 can be discharged through the pump return port 630 and the pump drain port 620, or pass through the pump return port 630, the washing pump 600, the pump water inlet 610, the lower spray part 400, and the upper spray part 500 in sequence to form an internal circulation of washing water.

[0061] The lower heater 141 is responsible for heating the central cavity 140 to boil the water in the inner container 100 to generate steam, thereby achieving steam sterilization.

[0062] In some embodiments of the present invention, reference Figure 9 、 Figure 10An input chamber 800 is provided on the rear side of the inner tank cavity 110, and an input chamber outlet 810 is provided on the front side of the input chamber 800, which is connected to the inner tank cavity 110. The input chamber 800 is provided with a hot air pipe 801 which is connected to the lower pipe section 410. The input chamber 800 is provided with a water pump outlet pipe 162 which is connected to the water pump 160. The water pump 160 is connected to an external water source, and the water flow can enter the inner tank cavity 110 through the water pump 160 and the input chamber outlet 810 in sequence.

[0063] The input chamber 800 has a built-in heater 820, and a fan 830 is provided on the input chamber 800. The heater 820 can generate heat to form a hot air flow. Part of the hot air flow can pass through the input chamber 800 and the hot air pipe 801 into the lower pipe section 410, and the other part of the hot air flow can enter the inner tank cavity 110 through the input chamber 800 and the input chamber outlet 810.

[0064] When cleaning a feeding bottle, the feeding bottle is first placed in the inner chamber 110. The water pump 160 pumps water and injects the water into the input chamber 800 through the water pump outlet pipe 162. The water in the input chamber 800 then flows through the input chamber outlet 810 to add water to the inner chamber 110. When the inner chamber 110 has enough water, the lower spray portion 400 and the upper spray portion 500 can draw water from the inner chamber 110 to rinse the feeding bottle and clean it.

[0065] 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 air flow. Part of the hot air flow is blown into the inner chamber 110 through the input chamber outlet 810, drying the bottles, the lower spray part 400, the upper spray part 500, and the inner wall of the inner chamber 110. The other part of the hot air flow passes through the hot air pipe 801 and enters the lower spray part 400 and the upper spray part 500, drying the interior of the lower spray part 400 and the upper spray part 500.

[0066] In a further embodiment of the present invention, a spray rack air duct 424 is provided on the lower fixed spray rack 420. A spray rack air duct horn inlet 425 is provided at the input end of the spray rack air duct 424, which faces the input chamber outlet 810. Spray rack air duct outlets 426 are distributed throughout the spray rack air duct 424. When hot air flows through the input chamber outlet 810 and into the inner chamber 110, a portion of the hot air can be blown into the spray rack air duct horn inlet 425, then enter the spray rack air duct 424 and be ejected from the spray rack air duct outlet 426. This design facilitates more even distribution of hot air within the inner chamber 110 for hot air drying.

[0067] In a further embodiment of the present invention, referring to Figure 9The input chamber outlet 810 is covered with a water baffle 811, and the upper side of the water baffle 811 has a horizontal rotating shaft, which is connected to the hole wall of the input chamber outlet 810. The hole wall of the input chamber outlet 810 is provided with a water baffle limiting portion, and the water baffle limiting portion can support the rear side wall of the water baffle 811, and the water baffle 811 can flip forward. When the water baffle 811 is in a vertical state, it can block the input chamber outlet 810, and when the water baffle 811 is in a flipped state, it can open the input chamber outlet 810. This one-way opening and closing design of the water baffle 811 ensures that the water or hot air in the input chamber 800 can flush the water baffle 811 and enter the inner liner cavity 110, while the water or airflow in the inner liner cavity 110 cannot enter the input chamber 800 in the reverse direction.

[0068] In some specific embodiments of the present invention, the water pump 160 takes in water through a water pump inlet pipe 161 and discharges water through a water pump outlet pipe 162 .

[0069] In some embodiments of the present invention, a water tank 170 is provided next to the inner container 100, and a water tank cover 171 is provided on the water tank 170. The water pump 160 is connected to the water tank 170 via a water pump inlet pipe 161. That is, the water pump 160 can pump water from the water tank 170.

[0070] In some embodiments of the present invention, reference Figure 10 、 Figure 11 The bottle cleaning device of the present invention also includes a tee 900 having a first tee opening 910 on its upper side, and a second tee opening 920 and a third tee opening 930 on its lower side. The input chamber 800 is connected to the first tee opening 910 via an air pressure balance pipe 802. The inner chamber 110 has a pump drain port 620 for the washing pump 600 on its lower side. The drain valve of the pump drain port 620 is connected to the second tee opening 920 via a front section 621 of the drain pipe. The third tee opening 930 is externally connected to a rear section 622 of the drain pipe. The input chamber 800 can be connected to the tee 900 through the air pressure balance pipe 802, the first opening 910 of the tee and the tee 900 in sequence to achieve air pressure balance between the input chamber 800 and the tee 900, and the water flow in the inner tank cavity 110 can be discharged through the pump drain outlet 620, the front section 621 of the drain pipe, the tee 900 and the rear section 622 of the drain pipe in sequence.

[0071] The tee 900 plays the role of balancing the air pressure during drainage, avoiding backflow during the drainage process. The tee 900 has three interfaces, namely the first opening 910 of the tee on the upper side, the second opening 920 of the tee on the lower side, and the third opening 930 of the tee. In order to achieve balanced regulation of air pressure, the air pressure balance pipe 802 passing between the input chamber 800 and the first opening 910 of the tee is ventilated. At the lower side of the inner tank cavity 110, in conjunction with the washing pump 600, the pump outlet 620 of the washing pump 600 is connected to the second opening 920 of the tee through the front section 621 of the drainage pipe, and the third opening 930 of the tee is responsible for the external drainage pipe rear section 622 to form a whole drainage pipe structure in series.

[0072] During the actual drainage process, the water in the inner tank cavity 110 passes through the pump drain port 620, the front section of the drain pipe 621, and then through the inner cavity of the tee 900, and is finally discharged from the outside of the device through the rear section of the drain pipe 622. At the same time, the gas inside the input chamber 800 can pass through the air pressure balance pipe 802 and the first opening 910 of the tee in turn, and finally connect with the tee 900, thereby ensuring that the air pressure between the input chamber 800 and the tee 900 reaches a balanced state. In this way, the tee 900 can achieve dynamic consistency between the air pressure of the outside world and the inner tank cavity 110, so as to prevent the backflow of wastewater from the outside into the inner tank cavity 110, and also prevent the water in the inner tank cavity 110 from failing to start due to reasons such as the loose valve of the washing pump 600, which causes the water in the inner tank to be unable to be discharged normally.

[0073] In a further embodiment of the present invention, a tee-shaped one-way valve disc 940 is provided over the first opening 910 of the tee-shaped valve. The tee-shaped one-way valve disc 940 allows fluid from the air pressure equalization pipe 802 to enter the inner cavity of the tee-shaped valve 900, while preventing fluid within the tee-shaped valve 900 from entering the air pressure equalization pipe 802. This prevents water within the tee-shaped valve 900 from flowing back into the air pressure equalization pipe 802.
