[0024] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.
[0025] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this disclosure. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this disclosure provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0026] To ensure consistent wetting across the mopping device, cleaning equipment typically features two overflow outlets spaced apart, with water from the tank supplied to each outlet via two hoses. However, in current technology, the two hoses are of different lengths, resulting in varying water volumes from the two overflow outlets, or even only one outlet dispensing water, negatively impacting the user experience.
[0027] To address the technical problem that the different lengths of the two water pipes result in different water volumes from the two overflow outlets, or even only one overflow outlet, affecting the user experience, this disclosure provides a cleaning device and a cleaning system.
[0028] Referring to Figures 1, 2, and 3, a first aspect embodiment of this disclosure provides a cleaning device comprising: a housing 10, a water tank 20, a first pipe 30, and a second pipe 40. The housing 10 has at least one first hole 11 and at least one second hole 12. The water tank 20 is disposed within the housing 10. One end of the first pipe 30 is in fluid communication with the first hole 11, and the other end is in fluid communication with the water tank 20. One end of the second pipe 40 is in fluid communication with the second hole 12, and the other end is in fluid communication with the water tank 20. The length of the first pipe 30 is greater than the length of the second pipe 40, and the flow rates in the first pipe 30 and the second pipe 40 are the same.
[0029] Cleaning equipment can be a sweeping robot, a mopping robot, or a robotic vacuum cleaner.
[0030] The flow rates in the first pipe 30 and the second pipe 40 are the same, but not absolutely the same. That is to say, the sameness of the flow rates in the first pipe 30 and the second pipe 40 includes being roughly the same. The tolerance range between the flow rates in the first pipe 30 and the second pipe 40 can be within 10%.
[0031] Since the housing 10 has a first hole 11 and a second hole 12, the water tank 20 is located on the housing 10 and is supported by the housing 10 to ensure the stability of the water tank 20 installation.
[0032] Since one end of the first pipe 30 is connected to the first hole 11 and the other end is connected to the water tank 20, the first pipe 30 can transport water from the water tank 20 to the first hole 11. Since one end of the second pipe 40 is connected to the second hole 12 and the other end is connected to the water tank 20, the second pipe 40 can transport water from the water tank 20 to the second hole 12.
[0033] In fluid dynamics, the longer the pipe, the greater the resistance encountered by the fluid flow. Since the length of the first pipe 30 is greater than that of the second pipe 40, the water flow in the first pipe 30 will encounter greater resistance than the water flow in the second pipe 40. However, since the flow rates in the first pipe 30 and the second pipe 40 are the same, the amount of water supplied by the first pipe 30 to the first hole 11 is the same as the amount of water supplied by the second pipe 40 to the second hole 12, and the water output from the first hole 11 is the same as the water output from the second hole 12. This ensures that the overall wetting effect of the cleaning element is similar, thus improving the user experience.
[0034] The size of the orifice directly affects the flow rate of the fluid; the larger the orifice, the greater the amount of fluid that can pass through. In some embodiments, in order to ensure that the flow rates in the first pipe 30 and the second pipe 40 are the same, the orifice diameter of the first orifice 11 is larger than that of the second orifice 12, so that the first orifice 11 has a larger potential outflow rate than the second orifice 12.
[0035] Because the first pipe 30 is relatively long, its internal water flow resistance is relatively high. To compensate for this resistance, the diameter of the first hole 11 is larger than that of the second hole 12 to increase the water output of the first hole 11. Therefore, although the resistance of the first pipe 30 is relatively high, the water output of the first pipe 30 can be smooth through the first hole 11, and the water output of the first hole 11 can still match the water output of the second hole 12, so that the flow rate in the first pipe 30 and the second pipe 40 is the same, so as to ensure that the overall wetting effect of the cleaning element is similar and improve the user experience.
[0036] Please refer to Figures 1 and 3. In some embodiments, in order to ensure that the water flow rate of the first hole 11 can match the water flow rate of the second hole 12, the second hole 12 is closer to the water tank 20 than the first hole 11. The position of the second hole 12 relative to the first hole 11 results in higher water pressure in the second hole 12, giving the second hole 12 a greater flow potential than the first hole 11. However, the diameter of the first hole 11 is larger than the diameter of the second hole 12, so that the water flow rate of the first hole 11 can match the water flow rate of the second hole 12.
[0037] In some embodiments, the number of first holes 11 is at least one, that is, the number of first holes 11 can be one or more, and the number of first holes 11 can be selected according to the area of the wetting area of the cleaning element.
[0038] The number of second holes 12 is at least one; that is, the number of second holes 12 can be one or more, and the number of first holes 12 can be selected according to the area of the wetting area of the cleaning element.
[0039] Please refer to Figures 2, 4, and 5. In some embodiments, in order to deliver water from the water tank 20 to the first hole 11 and the second hole 12 respectively, the cleaning device further includes a three-way pipe 50. The three-way pipe 50 has an inlet end 51, a first outlet end 52, and a second outlet end 53. The inlet end 51 is in fluid communication with the water tank 20, the first outlet end 52 is in fluid communication with the first pipe 30, and the second outlet end 53 is in fluid communication with the second pipe 40.
[0040] Water in the water tank 20 enters the three-way pipe 20 through the inlet end 51, and then is transported to the first pipe 30 through the first outlet end 52. The first pipe 30 transports the water to the first hole 11, and then to the second pipe 40 through the second outlet end 53. The second pipe 40 transports the water to the second hole 12. At the same time, it is not necessary to open multiple outlet holes on the water tank 20 to ensure the integrity of the water tank 20 structure.
[0041] Please refer to Figure 5. In some embodiments, in order to allow the water in the water tank 20 to smoothly enter the three-way pipe 50, the water inlet 51 is located at the main pipe of the three-way pipe 50. The water in the water tank 20 can smoothly enter the main pipe of the three-way pipe 50 through the water inlet 51, and then be distributed by the main pipe of the three-way pipe 50 to the first water outlet 52 and the second water outlet 53.
[0042] Of course, in some other embodiments, the water inlet 51 is located in one of the branches of the three-way pipe 50. The water in the water tank 20 can smoothly enter one of the branches of the three-way pipe 50 through the water inlet 51, and be transported by the main pipe of one of the branches of the three-way pipe 50 to the main pipe of the three-way pipe 50, and then distributed to the first water outlet 52 and the second water outlet 53 through the main pipe of the three-way pipe 50.
[0043] In some embodiments, the first outlet 52 is located at the main pipe of the tee pipe 50 to smoothly deliver water in the main pipe of the tee pipe 50 to the first pipe 30.
[0044] Of course, in some other embodiments, the second outlet 53 is located at the main pipe of the tee pipe 50 so as to smoothly transport the water in the main pipe of the tee pipe 50 to the second pipe 40.
[0045] In some embodiments, the inlet end 51 and the first outlet end 52 are located at the two ends of the main pipe of the tee pipe 50, and the second outlet end 53 is located at one of the branch pipes of the tee pipe 50 to form a T-shaped tee, so that the inlet and outlet of the tee pipe 50 are smooth.
[0046] Please refer to Figures 1 and 2. In some embodiments, in order to ensure that the flow rates in the first pipe 30 and the second pipe 40 are the same, the heights of the first outlet 52 and the second outlet 53 are different. Preferably, the height of the first outlet 52 is lower than the height of the second outlet 53. According to the principle of fluid statics, a natural pressure difference will be formed between the first outlet 52 and the second outlet 53. This pressure difference can be used to control the flow rate. Under the action of pressure difference and gravity, the water flowing out of the second outlet 53 has a higher pressure than the first outlet 52, so that the flow rate of the water entering the first pipe 30 from the first outlet 52 meets the requirements, thereby ensuring that the flow rates in the first pipe 30 and the second pipe 40 are the same.
[0047] Referring to Figures 1 and 4, in some embodiments, in order to transport water from the water tank 20 to the tee pipe 50, the cleaning device further includes a connecting pipe 60. The connecting pipe 60 is in fluid connection between the water tank 20 and the water inlet 51, and the connecting pipe 60 transports water from the water tank 20 to the tee pipe 50 through the water inlet 51.
[0048] The connecting pipe 60 can be a U-shaped pipe, which can adapt to various installation environments and space constraints, so as to facilitate the connection between the tee pipe 50 and the water tank 20.
[0049] Referring to Figure 1, in some embodiments, in order to transport water in the water tank 20 to the first pipe 30 and the second pipe 40, the water tank 20 is provided with a water inlet 21 and an overflow hole 22. The overflow hole 22 is in fluid communication with the first pipe 30 and the second pipe 40.
[0050] When water needs to be supplied to the water tank 20, water from an external water source can enter the water tank 20 through the inlet 21. The water in the water tank 20 can be supplied to the first pipe 30 and the second pipe 40 through the overflow hole 22. The first pipe 30 delivers water to the first hole 11, and the second pipe 40 delivers water to the second hole 12.
[0051] When the cleaning equipment includes a tee pipe 50, the overflow hole 22 is in fluid communication with the tee pipe 50.
[0052] In some embodiments, in order to ensure that water can smoothly enter the water tank 20, the water inlet 21 is located at the top of the water tank 20, so that water can flow from the top of the water tank 20. Under the action of gravity, the water will naturally fall into the water tank 20 and will not be affected by the water pressure inside the water tank 20, thus ensuring the stability of the water inlet.
[0053] Moreover, the water inlet 21 is located at the top of the water tank 20, allowing water to flow in from the top of the water tank 20. This ensures that the water tank 20 maintains a relatively uniform water level during the filling process, thereby maximizing the use of the storage space of the water tank 20.
[0054] Please refer to Figures 1 and 2. In some embodiments, in order to ensure a stable water supply from the water tank 20 to the first pipe 30 and the second pipe 40, the overflow hole 22 is located at the top of the water tank 20. After water enters the water tank 20 through the inlet hole 21, it will gradually fill the water tank 20. When the water tank 20 is full, the inlet hole 21 will continue to supply water to the water tank 20, causing the water pressure in the water tank 20 to be too high. At this time, the water in the water tank 20 is supplied to the first pipe 30 and the second pipe 40 through the overflow hole 22, thereby balancing the water pressure and ensuring a stable water pressure supplied to the first pipe 30 and the second pipe 40.
[0055] In some embodiments, to supply water to different areas of a cleaning element, the cleaning device further includes a cleaning element. The cleaning element is disposed on the housing 10 and on opposite sides of the housing 10, respectively, as is the water tank 20. The cleaning element is opposite to the first hole 11 and the second hole 12. The cleaning element may be a mop.
[0056] The first hole 11 supplies water from the first pipe 30 to the area in the cleaning element corresponding to the first hole 11, and the second hole 12 supplies water from the second pipe 40 to the area in the cleaning element corresponding to the second hole 12. Since the length of the first pipe 30 is greater than the length of the second pipe 40, the flow rates in the first pipe 30 and the second pipe 40 are the same. Therefore, the water output of the first hole 11 can match the water output of the second hole 12, so that the water supplied by the first hole 11 and the second hole 12 to different areas of the cleaning element is equivalent, thereby ensuring that the overall wetting effect of the cleaning element is similar and improving the user experience.
[0057] In some embodiments, in order to supply water to different cleaning elements, the cleaning device further includes two cleaning elements located at the bottom of the housing 10, with the two cleaning elements respectively opposite to the first hole 11 and the second hole 12.
[0058] The first hole 11 supplies water from the first pipe 30 to the cleaning element opposite to the first hole 11, and the second hole 12 supplies water from the second pipe 40 to the other cleaning element opposite to the first hole 11. Since the length of the first pipe 30 is greater than the length of the second pipe 40, the flow rates in the first pipe 30 and the second pipe 40 are the same. Therefore, the water output of the first hole 11 can match the water output of the second hole 12, so that the amount of water supplied by the first hole 11 and the second hole 12 to the two cleaning elements is equivalent, thereby ensuring that the wetting effect of the two cleaning elements is similar and improving the user experience.
