Description

Technical Field

[0001] This utility model relates to the field of baby bottle cleaning machine technology, and in particular to a baby bottle cleaning machine. Background Technology

[0002] With the improvement of living standards, the market demand for maternal and infant cleaning and disinfection products is growing. In the field of baby bottle cleaning, bottle washing machines are becoming increasingly popular among parents. However, in the drain pipes of bottle washing machines, the wastewater after washing often flows back due to fluctuations in air pressure within the pipes. This not only contaminates the bottles, but also easily breeds bacteria in the cleaning chamber and various pipes, resulting in a very poor user experience.

[0003] To address this, patent number 2022207802751 discloses an automatic cleaning machine, including a base, a washing chamber, a water tank, and a cover. The water tank is located on one side of the washing chamber and connected to it. A signal switch is located above the water tank, and the cover is closed onto the washing chamber to connect the signal switch. This automatic cleaning machine can automatically trigger the signal switch, facilitating subsequent cleaning operations.

[0004] The backflow prevention function of the aforementioned automatic cleaning machine relies entirely on the internal mechanism of the diaphragm pump. As the core component of the diaphragm pump, the diaphragm will fatigue and age under long-term reciprocating motion, causing the pump's sealing and backflow prevention performance to fail. This requires the diaphragm pump to be replaced regularly, and the process of replacing the diaphragm is often quite complicated. Utility Model Content

[0005] In view of the shortcomings or problems existing in the prior art, this disclosure provides a baby bottle cleaning machine with a simple structure that can effectively prevent sewage backflow caused by pipeline pressure fluctuations.

[0006] The technical solution adopted by this disclosure to solve the above-mentioned technical problem is: a baby bottle washing machine, comprising: case; The base is detachably connected to the housing; An inner liner is located inside the shell, and the inner liner forms a cleaning chamber. A water collection assembly is disposed between the inner tank and the base, and the water collection assembly is connected to the cleaning chamber; A drainage assembly, including a drainage pump and a drainage pipe, wherein the drainage pump is disposed between the inner liner and the base; The drainage pipe includes a first drainage pipe and a second drainage pipe. One end of the first drainage pipe is used to connect to the water collection assembly, and the other end is used to connect to the inlet of the drainage pump. The second drainage pipe is connected to the outlet of the drainage pump. The first drainage pipe is detachably equipped with a first check valve, and the second drainage pipe is detachably equipped with a second check valve.

[0007] In a preferred embodiment, the water collection assembly includes a water collection chamber and a filter chamber that are interconnected. The first drain pipe is connected to the water collection chamber. A drain outlet is provided at the bottom of the inner tank. An opening is provided at the top of the filter chamber. The drain outlet is positioned directly opposite the opening. A filter element is detachably connected to the filter chamber. The filter element is located below the opening, and the lateral dimension of the filter element is larger than the size of the opening.

[0008] By adopting the above technical solution, the water entering the water collection chamber is treated by the filter element, ensuring the cleanliness of the water pumped into the cleaning chamber for circulation; in addition, the drain outlet is set directly opposite the opening of the filter chamber, so that the washing water in the cleaning chamber can fall vertically onto the filter element under the action of gravity, improving the filtration efficiency.

[0009] In a preferred embodiment, a washing pump is provided on the side of the drain pump, a spray assembly is provided in the inner tank, the water inlet of the spray assembly is connected to the washing pump, and the water collection chamber is connected to the washing pump through a first pipe.

[0010] By adopting the above technical solution, the water in the water collection chamber passes through the first pipe and the washing pump in sequence, and is finally sprayed out by the spray assembly to clean the baby bottles in the cleaning chamber, thereby achieving the purpose of recycling the washing water and making the cleaning machine more energy-saving and environmentally friendly.

[0011] In a preferred embodiment, the water collection cavity is provided with a first water outlet and a second water outlet. The first water outlet is located on the side wall of the water collection cavity, and the second water outlet is located on the bottom wall of the water collection cavity. The first water outlet is used to connect to a first pipe, and the second water outlet is used to connect to a first drainage pipe.

[0012] By placing the first outlet on the side wall of the water collection chamber, impurities that settle at the bottom of the water collection chamber can be prevented from entering the washing pump and spray assembly, reducing the risk of damage to components such as the impeller of the washing pump and the risk of the spray holes of the spray assembly being blocked by impurities. Placing the second outlet on the bottom wall of the water collection chamber can ensure that the sewage and sediment in the water collection chamber are drained to the maximum extent.

[0013] In a preferred embodiment, the filter chamber has a first end and a second end that are disposed opposite to each other. The first end is connected to the water collection chamber through a first through hole located at the upper part of the water collection chamber. The second end is provided with an installation port for the filter element to enter.

[0014] By adopting the above technical solution, the water filtered by the filter element enters the water collection chamber through the first through hole. The first through hole is located at the top of the water collection chamber, so that the water in the filter chamber can flow naturally and smoothly into the water collection chamber under the action of gravity.

[0015] In a preferred embodiment, a heating element is provided at the bottom of the inner liner, which is used to heat the water in the cleaning chamber.

[0016] By installing a heating element in the inner tank, the washing water in the cleaning chamber can be heated efficiently, thereby achieving a better cleaning effect. The heating element is located at the bottom of the inner tank, which can directly heat the washing water, avoiding heat loss caused by transporting hot water through long pipes.

[0017] In a preferred embodiment, a liquid level sensor is also provided at the bottom of the inner liner, which is used to monitor the amount of water in the cleaning chamber.

[0018] The liquid level sensor can monitor the amount of water in the cleaning chamber in real time. Before the heating element starts working, the liquid level sensor will first check whether there is enough water in the cleaning chamber to avoid dry burning.

[0019] In a preferred embodiment, the shell is constructed with a first receiving portion and a second receiving portion, the inner liner is housed in the first receiving portion, and the second receiving portion forms a water tank.

[0020] By adopting the above technical solution, the inner tank and water tank can be integrated into the same shell, making the cleaning machine structure more compact. The cleaning machine itself has a water tank, so users do not need to connect an external water tank, making it more convenient to use.

[0021] In a preferred embodiment, a water delivery assembly is also provided between the inner liner and the base. The water delivery assembly includes a water inlet pump and a pipe assembly. The pipe assembly includes a first water delivery pipe and a second water delivery pipe. One end of the first water delivery pipe is used to connect to the water tank, and the other end is used to connect to the water inlet of the water inlet pump. One end of the second water delivery pipe is used to connect to the cleaning chamber, and the other end is used to connect to the water outlet of the water inlet pump.

[0022] By adopting the above technical solution, on the one hand, the location of the water supply component saves more space, and on the other hand, by placing the water inlet pump at a low position, so that its water inlet end is lower than the water tank, the water can be naturally drawn by gravity, thus avoiding the "air suction" or "cavitation" phenomenon that may occur when the water inlet pump is at a high position.

[0023] In a preferred embodiment, the system further includes a cover, which includes a closing portion and a grip portion disposed on the closing portion, the closing portion covering the top of the housing.

[0024] The cover not only prevents steam from splashing out during high-temperature cleaning or drying, but also effectively reduces heat loss from the cleaning chamber; the grip makes it easier for users to close or remove the cover.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: A first check valve is installed in the first drainage pipe to prevent sewage remaining in the drainage pump and the first drainage pipe from flowing back into the water collection assembly, thus avoiding contamination of the clean water in the water collection assembly; a second check valve is installed in the second drainage pipe to prevent external sewage (such as sewer water) and sewage remaining in the second drainage pipe from flowing back into the drainage pump; the first and second check valves provide a certain sealing effect, closing the passage when the cleaning machine is not in operation, preventing odors and bacteria from entering the water collection assembly and the cleaning chamber; when the first or second check valve is damaged, the user can replace it themselves, which is simpler and more convenient than replacing the diaphragm in a diaphragm pump.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0030] Please refer to Figure 1 and Figure 2As shown, this application discloses a baby bottle washing machine, including a housing 1 and a base 3. The base 3 is located below the housing 1 and is detachably connected to the housing 1. An inner liner 2 is provided inside the housing 1, and the inner liner 2 forms a washing chamber for accommodating and washing baby bottles. A water collection assembly 7 is provided between the inner liner 2 and the base 3, and the water collection assembly 7 communicates with the washing chamber. The water collection assembly 7 is used to collect the washing water flowing down from the washing chamber. A drain assembly is also provided, which includes a drain pump 20 and a drain pipe. The drain pump 20 is located between the inner liner 2 and the base 3. The drain pipe includes a first drain pipe 21 and a second drain pipe 22. One end of the first drain pipe 21 is used to connect to the water collection assembly 7, and the other end is used to connect to the water inlet of the drain pump 20. The second drain pipe 22 is connected to the water outlet of the drain pump 20. A first check valve is detachably provided on the first drain pipe 21, and a second check valve is detachably provided on the second drain pipe 22. The drainage assembly is used to discharge sewage and sediment from the water collection assembly 7. This sewage and sediment are discharged sequentially through the first drainage pipe 21, the drainage pump 20, and the second drainage pipe 22. After drainage, a small amount of sewage may remain in the drainage pump 20 and the first drainage pipe 21. A first check valve is installed in the first drainage pipe 21 to prevent the sewage remaining in the drainage pump 20 and the first drainage pipe 21 from flowing back into the water collection assembly 7, thereby avoiding contamination of the clean water in the water collection assembly 7. The second drainage pipe 22 is usually directly connected to the sewer or sewage tank. A second check valve is installed in the second drainage pipe 22 to prevent external sewage (such as water from the sewer or sewage tank) and the sewage remaining in the second drainage pipe 22 from flowing back into the drainage pump 20. In addition, the first and second check valves also play a certain sealing role, closing the passage when the cleaning machine is not working, preventing odors and bacteria from entering the water collection assembly 7 and the cleaning chamber. When the first or second check valve is damaged, the user can replace it himself. Compared with replacing the diaphragm of a diaphragm pump, replacing the check valve is simpler and more convenient.

[0031] In some embodiments, the first check valve and the first drain pipe 21 are connected by threads. Specifically, the first check valve has external threads at both ends, and the first drain pipe 21 has internal threads. During installation, the first check valve and the first drain pipe 21 can be screwed together using a wrench or other tools. During disassembly, they can be screwed out in the reverse direction. This connection method provides high mechanical strength and reliable connection.

[0032] In some embodiments, a quick-connect structure is provided at the connection between the first check valve and the first drain pipe 21. Specifically, the first check valve has connecting protrusions at both ends, the first drain pipe 21 has a connecting groove inside, and the first check valve usually also has a release latch. During installation, the connecting protrusions are inserted into the connecting groove to lock the first check valve to the first drain pipe 21. During disassembly, the release latch is pressed to remove the first check valve from the first drain pipe 21. This connection method allows for installation and disassembly without tools, and can be completed by hand.

[0033] In some embodiments, the first check valve and the first drain pipe 21 can also be connected by clamps. Tools such as screwdrivers or clamp pliers are required for installation and disassembly. However, in general, the clamp connection method is relatively convenient for installation and disassembly.

[0034] It is understandable that the connection between the first check valve and the first drain pipe 21 includes, but is not limited to, the above-mentioned connection methods, as does the connection between the second check valve and the second drain pipe 22, which will not be elaborated here.

[0035] Please refer to Figures 3-6 As shown, the water collection assembly 7 includes a water collection chamber 10 and a filter chamber 8 that are interconnected. A first drain pipe 21 is connected to the water collection chamber 10. A drain outlet 13 is located at the bottom of the inner tank 2. An opening is provided at the top of the filter chamber 8, with the drain outlet 13 directly opposite the opening. A filter element 9 is detachably connected to the filter chamber 8, located below the opening, and its lateral dimension is larger than the opening. Washing water containing impurities such as milk stains and food particles in the washing chamber falls vertically onto the filter element 9 through the drain outlet 13 under gravity. This improves filtration efficiency and ensures that the water entering the water collection chamber 10 has been treated by the filter element 9, guaranteeing the cleanliness of the water pumped into the washing chamber for circulation. The filter element 9 is installed in the filter chamber 8 via a snap-fit, plug-in, or threaded connection, making it easy to install, disassemble, clean, maintain, and replace. Specifically, the filter element 9 is a screen or a cylindrical filter.

[0036] Furthermore, such as Figure 7 and Figure 8As shown, the filter chamber 8 has a first end and a second end arranged opposite to each other. The first end is connected to the water collection chamber 10 through a first through hole, which is located at the upper part of the water collection chamber 10. The second end has an installation port 24 for the filter element 9 to enter. The axis of the installation port 24 is perpendicular to the axis of the drain outlet 13. The filter element 9 enters through the installation port 24 and is horizontally positioned in the filter chamber 8, so that the vertical projection of the drain outlet 13 falls completely on the filter element 9, ensuring that the water flowing down from the drain outlet 13 can be completely filtered by the filter element 9. The first through hole is located at the upper part of the water collection chamber 10, so that the water filtered by the filter element 9 in the filter chamber 8 can flow naturally and smoothly to the water collection chamber 10 under the action of gravity. It is understood that a window 25 is provided at a corresponding position on the housing 1. The window 25 should be corresponding to the installation port 24 to facilitate the user to clean, maintain and replace the filter element 9 regularly. To isolate the internal environment of the cleaning machine from the external environment, a cover plate can be installed at the window 25.

[0037] Understandably, a washing pump 14 is installed on the side of the drain pump 20, and a spray assembly is installed in the inner tank 2. The water inlet of the spray assembly is connected to the washing pump 14, and the water collection chamber 10 is connected to the washing pump 14 through the first pipe 23. The water in the water collection chamber 10 passes through the first pipe 23 and the washing pump 14 in sequence, and is finally sprayed out by the spray assembly to clean the baby bottles in the cleaning chamber, thereby achieving the purpose of recycling the washing water and making the cleaning machine more energy-efficient and environmentally friendly.

[0038] For details, please continue reading. Figures 3-6 As shown, the water collection chamber 10 is provided with a first outlet 11 and a second outlet 12. The first outlet 11 is located on the side wall of the water collection chamber 10, and the second outlet 12 is located on the bottom wall of the water collection chamber 10. The first outlet 11 is used to connect to the first pipe 23, and the second outlet 12 is used to connect to the first drainage pipe 21. By placing the first outlet 11 on the side wall of the water collection chamber 10, impurities that settle at the bottom of the water collection chamber 10 can be prevented from entering the washing pump 14 and the spray assembly, reducing the risk of damage to components such as the impeller of the washing pump 14 and the risk of the spray holes of the spray assembly being blocked by impurities. Placing the second outlet 12 on the bottom wall of the water collection chamber 10 can maximize the drainage of sewage and sediment in the water collection chamber 10.

[0039] like Figure 9 As shown, to improve the cleaning effect, a heating element 17 is installed at the bottom of the inner tank 2. The heating element 17 is used to heat the water in the cleaning chamber. Baby bottles contain a large amount of milk fat and protein residue. These residues are more easily dissolved and washed off under warm and hot water conditions, achieving a better cleaning effect. By placing the heating element 17 at the bottom of the inner tank 2, it can directly heat the washing water, avoiding heat loss caused by transporting hot water through long pipes. Specifically, the heating element 17 is a heating plate or heating wire.

[0040] In one embodiment of this disclosure, the cleaning machine further includes a controller, and a liquid level sensor 18 is provided at the bottom of the inner tank 2. The liquid level sensor 18 is used to monitor the amount of water in the cleaning chamber. Before the heating element 17 starts working, the liquid level sensor 18 first detects whether there is enough water in the cleaning chamber. When the liquid level sensor 18 confirms that the water level is higher than the safety threshold, the controller will control the heating element 17 to work. In this way, dry burning caused by insufficient water in the cleaning chamber can be effectively avoided.

[0041] Preferred, such as Figure 2 and Figure 8 As shown, the housing 1 has a first receiving portion 15 and a second receiving portion 16. The inner tank 2 is housed in the first receiving portion 15, and the second receiving portion 16 forms a water tank. Integrating the inner tank 2 and the water tank into the same housing 1 makes the cleaning machine structure more compact. In addition, the cleaning machine itself has a water tank, so users do not need to connect an external water tank, making it more convenient to use. A water supply assembly is also provided between the inner tank 2 and the base 3. The water supply assembly includes a water inlet pump 19 and a pipe assembly. The water inlet pump 19 is located between the inner tank 2 and the base 3. The pipe assembly includes a first water supply pipe and a second water supply pipe. One end of the first water supply pipe is used to connect to the water tank, and the other end is used to connect to the water inlet of the water inlet pump 19. One end of the second water supply pipe is used to connect to the cleaning chamber, and the other end is used to connect to the water outlet of the water inlet pump 19. The placement of the water supply component saves more space. In addition, the water inlet pump 19 is placed at a low position, with its inlet end lower than the water tank, so that gravity can be used to achieve natural water intake and avoid the "vacuuming" or "cavitation" phenomenon that may occur when the water inlet pump 19 is at a high position.

[0042] Please refer to Figure 1 As shown, in one embodiment of this disclosure, a cover 4 is also included. The cover 4 includes a closing portion 5 and a grip portion 6 disposed on the closing portion 5. The closing portion 5 is generally disc-shaped and closes onto the top of the housing 1. Specifically, the grip portion 6 is disposed on the top of the closing portion 5, and it is an arched handle, a hemispherical protrusion, or other common easy-to-grip structure. The cover 4 not only prevents steam from splashing out during high-temperature washing or high-temperature drying, but also effectively reduces heat loss in the washing chamber; the grip portion 6 makes it easier for the user to close or remove the cover 4.

[0043] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
