Description

Technical Field

[0001] This invention relates to a cleaning device, specifically a baby bottle cleaning machine with multiple water inlet methods. Background Technology

[0002] A baby bottle cleaner is a device specifically designed for cleaning baby bottles, aiming to help parents clean their babies' bottles more efficiently and safely. Currently, baby bottle cleaners on the market typically have a water tank, which users need to manually add water to for the cleaning cycle. However, this type of cleaner has the following drawbacks: First, after each or several cleaning cycles, users need to manually open the water tank to refill it, resulting in a poor user experience and cumbersome operation; second, the water tank capacity limits the number of bottles that can be cleaned in a single cycle or continuously, failing to meet the needs of large-scale or continuous cleaning; and third, it cannot be directly connected to municipal tap water to achieve fully automated "on-demand" water supply. Summary of the Invention

[0003] This invention provides a baby bottle cleaning machine with multiple water inlet methods. Its main purpose is to overcome the problems of existing baby bottle cleaning machines that can only supply water from the water tank when cleaning baby bottles, which makes the operation cumbersome, cannot be automated, and cannot provide continuous water supply.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A baby bottle cleaning machine with multiple water inlet methods includes a housing with a cleaning chamber inside. A water tank support is located at the rear bottom of the housing, and a water tank is placed on the support. The bottom of the housing contains a tap water inlet connector, a water tank outlet connector, a tap water inlet pipe, a water tank inlet pipe, a suction pipe, a water pump, a cleaning chamber inlet pipe, a washing pump, and a drain pump. A negative pressure valve is installed between the tap water inlet connector and one end of the tap water inlet pipe. The other end of the tap water inlet pipe is connected to one end of the suction pipe, and the other end of the suction pipe is connected to the inlet of the water pump. The water tank outlet connector is connected to the interior of the water tank and...

The outlet of the drain pump is connected to a first drain pipe. The pumping pump, washing pump, drain pump, solenoid valve, and flow meter are all controlled by a controller.

[0005] Furthermore, a T-joint is connected between the tap water inlet pipe and the pumping pipe, and the water pipe is connected to the T-joint.

[0006] Furthermore, the present invention also includes a water collection box, which is connected to the outer wall of the cleaning chamber. The water collection box is provided with a water inlet channel and a water outlet channel. The other end of the water inlet pipe of the cleaning chamber is connected to the water inlet channel. The lower part of the water collection box is provided with a water outlet channel that is connected to the water inlet channel. The water outlet channel is connected to the interior of the cleaning chamber. The first drain pipe is connected to the drain channel channel, and the drain channel channel is connected to a second drain pipe.

[0007] Furthermore, the bottom of the water collection box is provided with a water inlet, a sewage inlet, and a sewage outlet. The water inlet channel includes a first water inlet channel and a second water inlet channel that are interconnected. The first water inlet channel and the second water inlet channel are arranged side by side, and the top of the first water inlet channel and the top of the second water inlet channel are connected. The water inlet is connected to the first water inlet channel, and the second water inlet channel is connected to the outlet. The sewage inlet and the sewage outlet are arranged side by side, and both the sewage inlet and the sewage outlet are connected to the drainage channel. The other end of the water inlet pipe of the cleaning chamber is connected to the water inlet. The first drainage pipe is connected to the sewage inlet, and the second drainage pipe is connected to the sewage outlet.

[0008] Furthermore, the second water inlet channel is provided with a guide channel communicating with the water outlet and a baffle plate located on the right side of the guide channel. The bottom of the baffle plate is connected to a first guide plate that tilts downward to the left, and the bottom of the first guide plate is connected to a vertical second guide plate. The water collection box is also provided with a one-way channel located on the right side of the baffle plate. The top of the one-way channel is provided with a water passage hole communicating with the second water inlet channel. The top of the one-way channel is provided with a one-way valve that can block the water passage hole. An overflow gap is provided between the bottom of the one-way channel and the drainage channel.

[0009] Furthermore, the drain outlet is connected to the inlet of the washing pump and the inlet of the drain pump, the washing chamber has a spray arm assembly, the outlet of the washing pump is connected to the spray arm assembly, and the washing pump and the drain pump share a common inlet.

[0010] Furthermore, the outer wall of the cleaning chamber is connected to an air inlet channel, the cleaning chamber is provided with an air inlet, one end of the air inlet channel is connected to the air inlet, the other end of the air inlet channel is connected to a fan, and a PTC heater is provided inside the other end of the air inlet channel. The fan and the PTC heater are controlled by a controller, and the cleaning chamber is provided with a drying channel connected to the air inlet.

[0011] Furthermore, the bottom of the cleaning chamber is provided with a lamp hole, the bottom surface of the cleaning chamber is connected to a lamp panel, the top surface of the lamp panel is provided with a UV germicidal lamp, the UV germicidal lamp is directly opposite the lamp hole, the lamp hole is provided with a lampshade that allows light to pass through from the top, and the lamp panel is controlled by a controller.

[0012] Furthermore, the controller includes a control circuit board and a control panel. The control panel is located on the front end of the housing and is connected to the control circuit board. An electrical control box is located inside the bottom of the housing, and the control circuit board is located inside the electrical control box.

[0013] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following advantages: The present invention can supply water to the cleaning chamber in two ways: tap water inlet and water tank inlet. Under normal circumstances, tap water is used preferentially for water supply. The solenoid valve remains closed. When the water pump works, a negative pressure is generated, and the negative pressure valve automatically opens to allow tap water to flow in. The tap water drawn by the water pump enters the cleaning chamber through the cleaning chamber inlet pipe. The flow meter can sense the tap water flow. When the water pump stops working, the negative pressure disappears, and the negative pressure valve automatically closes under the tap water pressure or its own spring action. If the tap water supply is interrupted, the flow meter cannot sense the tap water flow. At this time, the water pump first stops working, the negative pressure valve remains closed, the solenoid valve opens, and the water pump resumes working to draw water from the water tank. The water in the water tank enters the cleaning chamber through the cleaning chamber inlet pipe. This invention prioritizes the use of tap water for continuous and automatic water supply. In the event of a tap water outage, the water in the tank can be used as backup water for the cleaning room. In this way, the baby bottle cleaning machine can achieve automation and continuous water supply, and users do not need to frequently add water to the tank. Attached Figure Description

[0026] Reference Figures 1 to 6A baby bottle cleaning machine with multiple water inlet methods includes a housing 1, a cleaning chamber 2 inside the housing 1, a water tank support 3 at the bottom rear end of the housing 1, and a water tank 4 placed on the water tank support 3. The bottom of the housing 1 is equipped with a tap water inlet connector 5, a water tank outlet connector 6, a tap water inlet pipe 7, a water tank inlet pipe 8, a water suction pipe 9, a water pump 10, a cleaning chamber inlet pipe 11, a washing pump 12, and a drain pump 13. A negative pressure valve 14 is provided between the tap water inlet connector 5 and one end of the tap water inlet pipe 7. The other end of the tap water inlet pipe 7 is connected to one end of the pumping pipe 9. The other end of the pumping pipe 9 is connected to the inlet of the pumping pump 10. The water tank outlet connector 6 is connected to the inside of the water tank 4 and one end of the water tank inlet pipe 8. The other end of the water tank inlet pipe 8 is provided with a solenoid valve 15. The solenoid valve 15 is connected to the pumping pipe 9 through a water pipe 16. One end of the cleaning chamber inlet pipe 11 is connected to the outlet of the pumping pump 10. The other end of the cleaning chamber inlet pipe 11 is connected to the inside of the cleaning chamber 2. A flow meter 17 is provided on the cleaning chamber inlet pipe 11. The outlet of the washing pump 12 is connected to the inside of the cleaning chamber 2. The bottom of the cleaning chamber 2 is provided with a drain outlet 18. The drain outlet 18 is connected to the inlet of the washing pump 12 and the inlet of the drain pump 13. The outlet of the drain pump 13 is connected to a first drain pipe 19. The water pump 10, washing pump 12, drain pump 13, solenoid valve 15, and flow meter 17 are all controlled by a controller. In this embodiment, the solenoid valve 15 is a normally closed solenoid valve. It should be noted that in actual use, the top of the housing 1 is provided with a top cover, which is not shown in the figure in this embodiment to better illustrate the structure inside the cleaning chamber 2.

[0027] Reference Figure 2 , Figure 4 and Figure 6 A three-way connector 20 is connected between the tap water inlet pipe 7 and the pumping pipe 9. The water supply pipe 16 is connected to the three-way connector 20. The three-way connector 20 is used to connect the water tank inlet pipe 8, the solenoid valve 15, the water supply pipe 16, and the pumping pipe 9.

[0028] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 9This invention prioritizes the use of tap water for water supply. The solenoid valve 15 remains closed. When the water pump 10 operates, it generates negative pressure, and the negative pressure valve 14 automatically opens, allowing tap water to flow in through the tap water inlet pipe 7 and the suction pipe 9. The tap water drawn by the water pump 10 enters the cleaning chamber 2 through the cleaning chamber inlet pipe 11, and the flow meter 17 can sense the flow of tap water. When the water pump 10 stops operating, the negative pressure disappears, and the negative pressure valve automatically closes under the pressure of the tap water or its own spring. If the tap water supply is interrupted, the flow meter 17 will not sense the flow of tap water when the water pump 10 is operating. In this case, the water pump 10 first stops operating, the negative pressure valve 14 remains closed, the solenoid valve 15 opens, and the water pump 10 resumes operation to draw water from the water tank 4. The water in the water tank 4 enters the cleaning chamber 2 through the water tank inlet pipe 8, the solenoid valve 15, the water pipe 16, the suction pipe 9, and the cleaning chamber inlet pipe 11. The negative pressure valve 14 is an existing structure, and its specific structure will not be described in detail here.

[0029] Reference Figure 3 , Figures 4 to 7 The invention also includes a water collection box 21, which is connected to the outer wall of the cleaning chamber 2. The water collection box 21 has an inlet channel and a drain channel 23. The other end of the cleaning chamber inlet pipe 11 is connected to the inlet channel. The lower part of the water collection box 21 has an outlet 24 connected to the inlet channel. The outlet 24 is connected to the interior of the cleaning chamber 2. Specifically, the cleaning chamber 2 has a through hole 25 connected to the outlet 24. Water in the inlet channel enters the cleaning chamber 2 through the outlet 24 and the through hole 25. The first drain pipe 19 is connected to the drain channel 23, and the drain channel 23 is connected to a second drain pipe 26.

[0030] Reference Figure 6 and Figure 7 The bottom of the water collection box 21 is provided with a water inlet 27, a sewage inlet 28, and a sewage outlet 29. The water inlet channel includes a first water inlet channel 221 and a second water inlet channel 222 that are interconnected. Specifically, the first water inlet channel 221 and the second water inlet channel 222 are arranged side by side, and the top of the first water inlet channel 221 and the top of the second water inlet channel 222 are connected. The water inlet 27 is connected to the bottom of the first water inlet channel 221, and the bottom of the second water inlet channel 222 is connected to the outlet 24. The sewage inlet 28 and the sewage outlet 29 are arranged side by side, and both the sewage inlet 28 and the sewage outlet 29 are connected to the drainage channel 23. The other end of the cleaning chamber water inlet pipe 11 is connected to the water inlet 27. The first drainage pipe 19 is connected to the sewage inlet 28, and the second drainage pipe 26 is connected to the sewage outlet 29.

[0031] Reference Figure 7 and Figure 8The second water inlet channel 222 is provided with a guide channel 31 communicating with the outlet 24 and a baffle plate 32 located on the right side of the guide channel 31. The bottom of the baffle plate 32 is connected to a first guide plate 33 that slopes downward to the left, and the bottom of the first guide plate 33 is connected to a vertical second guide plate 34. The water collection box 21 is also provided with a one-way channel 35 located on the right side of the baffle plate 32. The top of the one-way channel 35 is provided with a water passage hole 36 communicating with the second water inlet channel 222. The top of the one-way channel 35 is provided with a one-way valve 37 that can block the water passage hole 36. An overflow gap 38 is provided between the bottom of the one-way channel 35 and the drainage channel 23.

[0032] Reference Figure 4 , Figure 6 and Figure 7 The water collection box 21 integrates the additional water inlet and drainage channels of the cleaning chamber 2, further reducing the need for complex piping and making the piping structure more compact, thereby reducing the size of the bottle cleaner. The water in the inlet pipe 11 of the cleaning chamber first flows from the bottom to the top of the first inlet channel 221, and then flows down from the top of the second inlet channel 222 to the outlet 24. This prevents sewage in the cleaning chamber 2 from flowing back into the inlet channel through the outlet 24 and back into the cleaning chamber 2. After entering the second inlet channel 222, the water flows into the guide channel 31, and then, after being buffered by the first guide plate 33, it enters the outlet 24 from the side wall of the first inlet channel 221 and the second guide plate 34. The arrangement of the guide channel 31, the first guide plate 33 and the second guide plate 34 can prevent the water from directly rushing into the outlet 24 and reduce the flow rate of the water entering the outlet 24. At the same time, a buffer channel 30 connected to the outlet 24 can be formed between the baffle plate 32 and the one-way channel 35. The one-way valve 36 only opens when water from the second inlet channel 222 enters the one-way channel 35. If water from the drain channel 23 enters the one-way channel 35, the one-way valve 36 closes. If a small amount of water overflows from the second inlet channel 222, the water can pass through the water inlet 36 and open the one-way valve 36, thus entering the one-way channel 35. Finally, it flows into the drain channel 23 through the overflow gap 38. If sewage from the drain channel 23 enters the one-way channel 35, the one-way valve 36 is pressed and remains normally closed, preventing sewage from entering the second inlet channel 222.

[0033] Reference Figure 1 , Figure 3 , Figure 4 and Figure 6The drain outlet 18 is connected to the inlet of the washing pump 12 and the inlet of the drain pump 13. The washing chamber 2 has a spray arm assembly 39, and the outlet of the washing pump 12 is connected to the spray arm assembly 39. The spray arm assembly 39 is an existing structure and will not be described in detail here. The washing pump 12 and the drain pump 13 share a common inlet. Specifically, a connecting member 40 is provided between the washing pump 12 and the drain pump 13. The connecting member 40 is connected to the inlet of the washing pump 12 and the inlet of the drain pump 13, and the top of the connecting member 40 is connected to the drain outlet 18. When the baby bottle is being cleaned, the washing pump 12 operates. Water in the cleaning chamber 2 enters the washing pump 12 through the drain outlet 18 and the connecting piece 40, and then enters the spray arm assembly 39 from the outlet of the washing pump 12. Finally, it is sprayed out from the spray arm assembly 39 to clean the baby bottle. After the water in the cleaning chamber 2 circulates several times, the washing pump 12 stops working, and the drain pump 13 starts working. Wastewater in the cleaning chamber 2 enters the drain pump 13 through the drain outlet 18 and the connecting piece 40, and enters the drain channel 23 from the outlet of the drain pump 13 through the first drain pipe 19, and finally is discharged to the outside through the second drain pipe 26.

[0034] Reference Figure 1 , Figure 3 , Figures 5 to 7 The outer wall of the cleaning chamber 2 is connected to an air inlet channel 41. The cleaning chamber 2 is provided with an air inlet 42. One end of the air inlet channel 41 is connected to the air inlet 42, and the other end of the air inlet channel 41 is connected to a fan 43. A PTC heater 44 is provided inside the other end of the air inlet channel 41. The fan 43 and the PTC heater 44 are controlled by a controller. The cleaning chamber 2 is provided with a drying channel 45 connected to the air inlet 42. Multiple air outlets 451 are arranged around the top of the drying channel 45. After the baby bottles are cleaned, the fan 43 and the PTC heater 44 start working. The air generated by the fan 43 is heated by the PTC heater 44 to form hot air. The hot air enters the drying channel 45 in the cleaning chamber 2 through the air inlet channel 41 to dry the cleaned baby bottles.

[0035] Reference Figure 2 and Figure 3 The bottom of the cleaning chamber 2 is equipped with a lamp hole 46, and a lamp panel 47 is connected to the bottom surface of the cleaning chamber 2. A UV sterilization lamp (not shown in the figure due to view limitations) is mounted on the top surface of the lamp panel 47. The UV sterilization lamp faces the lamp hole 46, and a light-transmitting lampshade 48 is installed inside the lamp hole 46. The lamp panel 47 is controlled by a controller. After the baby bottles are dried, the lamp panel 47 controls the UV sterilization lamp to turn on, thereby starting the sterilization process on the baby bottles in the cleaning chamber 2.

[0036] Reference Figure 1 , Figure 2 and Figure 8 The controller includes a control circuit board 49 and a control panel 50. The control panel 50 is located on the front end of the housing 1 and is connected to the control circuit board 49.

The water pump 10, washing pump 12, drain pump 13, solenoid valve 15, flow meter 17, fan 43, PTC heater 44, and light panel 47 are all connected to the control circuit board 49. The control panel 50 is a touch panel and is used to drive the control circuit board 49. The control circuit board 49 is used to control the operation of the water pump 10, washing pump 12, drain pump 13, solenoid valve 15, fan 43, PTC heater 44, and light panel 47, and to receive sensing information from the flow meter 17. The electrical control box 51 provides waterproofing and dustproofing for the control circuit board 49. A power interface connected to the control circuit board 49 is located at the rear bottom of the housing 1. This power interface is used to connect to mains power to provide power to the bottle washing machine.
