[0041] Reference below Figure 1-Figure 12 A cleaning device 100 according to an embodiment of the present invention is described.

[0042] Reference Figure 1 , Figure 2 and Figure 3 According to the cleaning device 100 of the embodiment of the utility model, the cleaning device 100 comprises: a main unit 1, a first fan 2, a sewage bucket 3 and a floor brush assembly 4, wherein the first fan 2, the sewage bucket 3 and the floor brush assembly 4 are all arranged on the main unit 1, and the floor brush assembly 4 is arranged at the bottom of the main unit 1 for cleaning the floor. Fig.12 The floor brush assembly 4 is provided with a sewage suction port 41, which is connected to the sewage bucket 3, and the sewage bucket 3 is connected to the first fan 2. When the cleaning device 100 is working, the floor brush assembly 4 cleans the floor, the first fan 2 works to generate negative pressure in the sewage bucket 3, and suction is generated at the sewage suction port 41 to suck the sewage and garbage at the floor brush assembly 4 into the sewage bucket 3.

[0043] Reference Figure 3 and Figure 4A partition 5 is provided in the sewage bucket 3, and the partition 5 divides the internal space of the sewage bucket 3 into a first cavity 31 and a second cavity 32, wherein the first cavity 31 is used to separate sewage and solid waste, and a water filter hole 51 connecting the first cavity 31 and the second cavity 32 is provided on the partition 5, and the second cavity 32 is used to store sewage.

[0044] Reference Figure 3 , Figure 5 and Figure 6 The first cavity 31 is connected to the first fan 2 and the sewage suction port 41 respectively. When the first fan 2 is working, negative pressure is generated in the first cavity 31. When sewage and garbage enter the sewage barrel 3, they first enter the first cavity 31. The sewage in the first cavity 31 enters the second cavity 32 through the water filter hole 51, and the solid garbage in the first cavity 31 remains in the first cavity 31, thereby realizing solid-liquid separation.

[0045] In order to improve the solid-liquid separation efficiency of the first cavity 31, in the embodiment of the utility model, the second cavity 32 is also connected to the first fan 2. When the first fan 2 is running, there is a negative pressure difference between the first cavity 31 and the second cavity 32, so that the sewage in the first cavity 31 flows into the second cavity 32. The negative pressure difference between the first cavity 31 and the second cavity 32 improves the efficiency of the sewage in the first cavity 31 entering the second cavity 32.

[0046] According to the cleaning device 100 of the embodiment of the utility model, a negative pressure difference can be created between the first cavity 31 and the second cavity 32. The sewage in the first cavity 31 accelerates the rate of passing through the water filter hole 51 under the action of the negative pressure difference, reducing the risk of a large amount of sewage remaining in the first cavity 31, that is, reducing the probability of sewage entering the first fan 2, and improving the safety of the use of the cleaning device 100. In addition, the first cavity 31 and the second cavity 32 in the utility model are both connected to the first fan 2. Through one fan, not only can the sewage be sucked into the sewage bucket 3, but also the efficiency of solid-liquid separation in the first cavity 31 can be accelerated, thereby improving the utilization rate of the first fan 2 and reducing the cost of the cleaning device 100.

[0047] Reference Figure 3 , Figure 4 and Figure 6 In some specific embodiments, a diverter bracket 6 is further provided in the sewage bucket 3, and the diverter bracket 6 is provided with a first opening 61 communicating with the first fan 2 and a second opening 62 communicating with the first cavity 31. Figure 3 , Figure 7 and Figure 8 The diverter bracket 6 is also provided with a third opening 63 communicating with the second cavity 32 .

[0048] The first opening 61 is connected to the first fan 2. When the first fan 2 is working, there is suction at the first opening 61. Since the second opening 62 and the third opening 63 are both connected to the first opening 61, the suction at the first opening 61 is diverted to the second opening 62 and the third opening 63, so that there is negative pressure in the first cavity 31 and the second cavity 32.

[0049] When the water filter hole 51 is not covered, the second cavity 32 is connected with the first cavity 31 through the water filter hole 51, and the suction force of the third opening 63 returns to the first cavity 31 to cooperate with the suction force at the second opening 62 to extract sewage and garbage from the outside; when the water filter hole 51 is covered with sewage, the first cavity 31 is connected with the first fan 2 through the second opening 62, so that there is a negative pressure in the first cavity 31, but the first cavity 31 is also connected with the external environment through the sewage suction port 41, resulting in a larger negative pressure in the first cavity 31, and the second cavity 32 is only connected with the first fan 2 through the third opening 63, and the negative pressure in the second cavity 32 is lower, so that there is a negative pressure difference between the first cavity 31 and the second cavity 32, thereby accelerating the rate at which the sewage in the first cavity 31 passes through the water filter hole 51, and the sewage in the first cavity 31 continuously enters the second cavity 32.

[0050] In some further embodiments, the opening area of ​​the third opening 63 is greater than the opening area of ​​the second opening 62 .

[0051] Because the opening area of ​​the third opening 63 is larger than the opening area of ​​the second opening 62, the suction at the third opening 63 is stronger, resulting in a smaller negative pressure in the second cavity 32, further increasing the negative pressure difference between the first cavity 31 and the second cavity 32, further increasing the rate at which the sewage in the first cavity 31 enters the second cavity 32, and further reducing the probability of the sewage in the first cavity 31 entering the first fan 2.

[0052] In some embodiments, the opening area of ​​the first opening 61 is S1 , the opening area of ​​the second opening 62 is S2 , and the opening area of ​​the third opening 63 is S3 .

[0053] It should be noted that, in some embodiments, the flow splitter bracket 6 is provided with a first opening 61, and the opening area of ​​the first opening 61 is S1. In other embodiments, the flow splitter bracket 6 is provided with multiple first openings 61, and in this embodiment, the sum of the opening areas of the multiple first openings 61 is S1.

[0054] Similarly, in some embodiments, the flow splitter bracket 6 is provided with a second opening 62, and the opening area of ​​the second opening 62 is S2. In other embodiments, the flow splitter bracket 6 is provided with a plurality of second openings 62, and in this embodiment, the sum of the opening areas of the plurality of second openings 62 is S2.

[0055] Similarly, in some embodiments, the flow splitter bracket 6 is provided with a third opening 63, and the opening area of ​​the third opening 63 is S3. In other embodiments, the flow splitter bracket 6 is provided with a plurality of third openings 63, and in this embodiment, the sum of the opening areas of the plurality of third openings 63 is S3.

[0056] In the present invention, S2 / S1 satisfies: 1 / 3≤S2 / S1≤2 / 5. S3 / S1 satisfies: 3 / 5≤S3 / S1≤2 / 3.

[0057] When S2 / S1 is less than 1 / 3 and S3 / S1 is greater than 2 / 3, the opening area of ​​the second opening 62 is too small and the opening area of ​​the third opening 63 is too large. When the water filter hole 51 is covered, the first cavity 31 only absorbs external sewage and garbage through the suction force at the second opening 62. If the opening area of ​​the second opening 62 is too small, the suction force at the sewage suction port 41 is insufficient, which affects the cleaning device 100 from sucking external sewage and garbage.

[0058] When S2 / S1 is greater than 2 / 5 and S3 / S1 is less than 3 / 5, the opening area of ​​the third opening 63 is relatively small. When the water filter hole 51 is covered, the negative pressure difference between the first cavity 31 and the second cavity 32 is small, which may cause the effect of improving the solid-liquid separation efficiency to fail.

[0059] Therefore, in the embodiment of the utility model, S2 / S1 satisfies: 1 / 3≤S2 / S1≤2 / 5. S3 / S1 satisfies: 3 / 5≤S3 / S1≤2 / 3. When the cleaning device 100 is working, the suction port 41 always has sufficient suction to absorb external sewage and garbage. At the same time, when the water filter hole 51 is covered, there is a sufficiently large negative pressure difference between the first cavity 31 and the second cavity 32 to accelerate the efficiency of solid-liquid separation in the first cavity 31 and reduce the risk of sewage entering the first fan 2.

[0060] In some embodiments, S1 satisfies: S1 ≥ 400 mm 2 To ensure that when the cleaning device 100 is working, the suction port 41 always has sufficient suction force to absorb external sewage and garbage. At the same time, when the water filter hole 51 is covered, there is a sufficiently large negative pressure difference between the first cavity 31 and the second cavity 32 to accelerate the efficiency of solid-liquid separation in the first cavity 31 and reduce the risk of sewage entering the first fan 2.

[0061] In some specific embodiments, S1 may be 400 mm. 2 In some other embodiments, S1 can also be 410 mm 2 、420mm 2 , 450mm 2 , 500mm 2 And other values.

[0062] Reference Figure 3 , Figure 4 and Fig. 9 In some embodiments, the diverter bracket 6 is located at one end of the sewage bucket 3 close to the first fan 2, and a first opening 61 is provided on the side of the diverter bracket 6 facing the first fan 2. The opening area of ​​the first opening 61 is 400 mm 2 The shunt bracket 6 is provided with two second openings 62 on one side facing the first cavity 31, and the two second openings 62 are arranged at intervals, and the sum of the opening areas of the two second openings 62 is 133.33mm 2 (i.e., S2 / S1 is 1 / 3); a portion of the shunt bracket 6 extends toward the partition 5 and penetrates the partition 5 to extend to the second cavity 32, and the portion of the shunt bracket 6 located in the second cavity 32 is provided with two third openings 63, the two third openings 63 are spaced apart, and the sum of the opening areas of the two third openings 63 is 266.67 mm 2 (i.e. S3 / S1 is 2 / 3).

[0063] Through the above technical solution, it is ensured that when the cleaning equipment 100 is working, the suction port 41 always has sufficient suction force to absorb external sewage and garbage. At the same time, when the water filter hole 51 is covered, there is a sufficiently large negative pressure difference between the first cavity 31 and the second cavity 32 to speed up the efficiency of solid-liquid separation in the first cavity 31 and reduce the risk of sewage entering the first fan 2.

[0064] In some other embodiments, S2 / S1 may also be other values ​​such as 11 / 30, 2 / 5, etc. S3 / S1 may also be other values ​​such as 19 / 30, 3 / 5, etc.

[0065] Reference Figure 3 , Figure 4 and Figure 6 In some embodiments, the diverter bracket 6 is provided with a water retaining portion 64 located in the first cavity 31 , and the water retaining portion 64 is located between the water filter hole 51 and the second opening 62 , and the gas in the first cavity 31 is suitable for bypassing the water retaining portion 64 and entering the second opening 62 .

[0066] Through the above technical solution, after the air drives the sewage into the first cavity 31, the air needs to bypass the water retaining portion 64 from the side of the water retaining portion 64 to enter the second opening 62, and then flow to the first fan 2. Some sewage may have a tendency to flow to the second opening 62 driven by the air, but after the sewage contacts the water retaining portion 64, it is blocked by the water retaining portion 64, thereby reducing the risk of sewage entering the first fan 2 and improving the safety of the cleaning equipment 100.

[0067] Reference Figure 3 and Figure 6 In some embodiments, a filter element 7 for filtering water vapor is provided between the first opening 61 and the first fan 2 .

[0068] Through the above technical solution, when air containing water vapor flows toward the first fan 2, the filter element 7 filters out the water vapor in the air to prevent sewage from entering the first fan 2, thereby further reducing the risk of sewage entering the first fan 2 and improving the safety of the use of the cleaning device 100.

[0069] In some specific embodiments, the filter element 7 includes a Hypa water-proof soft glue 71 , and the Hypa water-proof soft glue 71 is disposed on the diversion bracket 6 and covers the first opening 61 .

[0070] In some further embodiments, the Hypa water-proof soft glue 71 is provided with at least two layers, and the two layers of the Hypa water-proof soft glue 71 are arranged at intervals. By providing multiple layers of the Hypa water-proof soft glue 71, the effect of filtering water vapor of the filter element 7 is further improved.

[0071] In some embodiments, the filter element 7 also includes a HEPA filter 72, which is disposed on the cover 34 of the sewage bucket 3. When the sewage bucket 3 is installed on the host 1, the HEPA filter 72 is connected to the first fan 2. When the first fan 2 is working, the air in the first cavity 31 bypasses the water retaining portion 64 and passes through the second opening 62, the first opening 61, the multi-layer HEPA waterproof soft rubber 71 and the HEPA filter 72 in turn before flowing to the first fan 2.

[0072] In the above technical solution, sewage and water vapor are blocked by various means, which effectively reduces the risk of sewage entering the first fan 2, reduces the probability of damage to the first fan 2, and improves the safety of the cleaning device 100.

[0073] Reference Figure 3 , Figure 4 and Fig.10 In some embodiments, the diverter bracket 6 is connected to the partition 5, and the diverter bracket 6 is detachably disposed in the sewage bucket 3. The diverter bracket 6, the partition 5, and a portion of the inner wall of the sewage bucket 3 define the first cavity 31 mentioned above.

[0074] When the cleaning device 100 performs cleaning work, sewage and garbage from the outside enter the first cavity 31, sewage enters the second cavity 32 through the water filter hole 51, and garbage remains in the first cavity 31. After the cleaning device 100 completes the cleaning work, the diverter bracket 6 can be removed from the sewage bucket 3. The diverter bracket 6 is connected to the partition 5, so that the partition 5 can be removed from the sewage bucket 3 together with the diverter bracket 6, thereby taking the solid garbage out of the sewage bucket 3, which is convenient for users to handle the solid garbage.

[0075] In some embodiments, the partition 5 is sealed to the inner wall of the sewage bucket 3 to separate the first cavity 31 and the second cavity 32 into isolated and independent cavities, ensuring the sealing of the second cavity 32 so that sewage can only enter the second cavity 32 through the water filter hole 51.

[0076] Reference Figure 3 , Figure 4 and Fig.10 In some specific embodiments, the partition 5 is constructed as a plate-like structure, and a first sealing ring 52 is provided on the outer periphery of the partition 5. When the partition 5 is located in the sewage bucket 3, the partition 5 divides the inner space of the sewage bucket 3 into a first cavity 31 and a second cavity 32. The first sealing ring 52 is sandwiched between the partition 5 and the inner wall of the sewage bucket 3 to ensure the sealing of the second cavity 32, so that the sewage can only enter the second cavity 32 through the water filter hole 51. When the partition 5 is removed from the sewage bucket 3 along with the diversion bracket 6, the partition 5 drives the solid garbage out of the sewage bucket 3 together.

[0077] The partition 5 in the above technical solution has a simple structure, which reduces the cost of the cleaning device 100.

[0078] Reference Figure 3 , Figure 4 and Fig.10 In some embodiments, the sewage bucket 3 includes a barrel body 33 and a cover body 34. The top of the barrel body 33 is provided with an opening. The cover body 34 is detachably arranged on the barrel body 33 to open or close the opening on the top of the barrel body 33. The diverter bracket 6 is arranged on the cover body 34, so that when the cover body 34 is removed from the barrel body 33, the diverter bracket 6 and the partition 5 are separated from the barrel body 33 together with the cover body 34.

[0079] Reference Figure 3 , Figure 4 and Fig.10 In some specific embodiments, a second sealing ring 341 is provided on the peripheral side of the cover body 34 . When the cover body 34 is installed on the barrel body 33 , the second sealing ring 341 is clamped between the cover body 34 and the barrel body 33 to prevent negative pressure leakage of the first cavity 31 .

[0080] Reference Figure 3 , Figure 4 and Fig.10 In some embodiments, the sewage bucket 3 further includes a water supply pipe 35 , a first end of the water supply pipe 35 is connected to the sewage suction port 41 , and a second end of the water supply pipe 35 passes through the partition 5 to be connected to the first cavity 31 .

[0081] When the cleaning device 100 is performing cleaning work, the first fan 2 is working, and the suction port 41 generates suction, and the external sewage and garbage enter the water supply pipe 35 through the suction port 41, and then enter the first cavity 31 through the water supply pipe 35, so that the sewage and solid garbage can be separated into solid and liquid in the first cavity 31.

[0082] In some specific embodiments, the first end of the water pipe 35 is integrally formed with the bottom wall of the barrel body 33, and an opening communicating with the sewage suction port 41 is formed on the outer side of the barrel body 33. The water pipe 35 extends upward along the length direction of the barrel body 33, and the partition 5 is provided with a first through hole. The partition 5 is connected to the water pipe 35 through the first through hole, that is, the water pipe 35 passes through the partition 5.

[0083] When the diverter bracket 6 and the partition 5 move toward the opening at the top of the barrel body 33 , the moving direction of the partition 5 is parallel to the extending direction of the water supply pipe 35 , so that the partition 5 will not interfere with the water supply pipe 35 when moving.

[0084] Reference Figure 3 , Figure 4 and Fig.10 In some embodiments, an opening 65 is provided on one side of the diverter bracket 6 adjacent to the water filter hole 51. When the diverter bracket 6 and the partition 5 are removed from the sewage bucket 3, the garbage between the diverter bracket 6 and the partition 5 can be poured out through the opening 65.

[0085] Because when the diverter bracket 6 and the partition 5 are pulled out of the barrel, the solid waste may fall directly from the open mouth 65, which may pollute the indoor environment or fall back into the sewage barrel 3. In order to avoid such a situation, refer to Figure 3 , Figure 4 and Figure 6 A blocking member 8 is also provided on the partition 5 , and the blocking member 8 is located between the water filtering hole 51 and the open mouth 65 .

[0086] By providing the blocking member 8 on the partition 5, the possibility of solid waste directly falling from the open mouth 65 when the diverter bracket 6 and the partition 5 are pulled out of the barrel body is avoided, thereby improving the reliability of the cleaning device 100.

[0087] Reference Figure 3 , Figure 4 and Figure 6 In some specific embodiments, the blocking member 8 is a strip structure disposed on the partition 5 , and the blocking member 8 extends along the extension direction of the opening 65 .

[0088] The blocking member 8 in the above technical solution has a simple structure and is easy to manufacture, thereby reducing the cost of the cleaning device 100 .

[0089] Reference Figure 3 , Figure 4 and Figure 6 In some further embodiments, the partition 5 is provided with a mounting hole 53 , and the blocking member 8 is formed as a plastic member, and a portion of the blocking member 8 is located in the mounting hole 53 to be mounted to the partition 5 .

[0090] That is to say, the blocking member 8 is inserted into the partition 5, and the blocking member 8 and the partition 5 are detachably connected, which is convenient for the user to remove the blocking member 8 to clean the solid waste on the partition 5, and the installation and removal method of the blocking member 8 and the partition 5 is simple, which reduces the installation and removal efficiency of the blocking member 8.

[0091] In some specific embodiments, the blocking member 8 includes a plurality of plug-in portions 81, which are arranged at intervals along the length direction of the blocking member 8. A plurality of mounting holes 53 are arranged on the partition 5 corresponding to the plurality of plug-in portions 81, and each plug-in portion 81 is inserted into a corresponding mounting hole 53. The coordination of the plurality of plug-in portions 81 and the plurality of mounting holes 53 enhances the stability of the connection between the blocking member 8 and the partition 5.

[0092] Reference Figure 3 , Figure 4 and Figure 6 In some embodiments, the partition 5 is provided with a guide surface 54 for guiding the sewage to flow toward the water filtering hole 51 .

[0093] Through the above technical solution, the sewage in the first cavity 31 can flow to the water filter hole 51 under the guidance of the guide surface 54, which is convenient for the sewage to enter the second cavity 32, further reducing the probability of sewage remaining in the first cavity 31 and further reducing the risk of sewage entering the first fan 2.

[0094] In some specific embodiments, the guide surface 54 is inclined relative to the sewage bucket 3 to guide the sewage to the water filter hole 51. The guide surface 54 in the embodiment of the present application has a simple structure and is easy to manufacture, thereby reducing the cost of the cleaning device 100.

[0095] In some specific embodiments, the partition 5 is constructed as a plate-like structure, and the water filter hole 51 is arranged on the side of the partition 5 close to the open mouth 65. The partition 5 is inclined relative to the length direction of the barrel body 33 so that the partition 5 forms an inclined surface on the side facing the first cavity 31 for guiding sewage to flow to the water filter hole 51, that is, the guide surface 54.

[0096] The guide surface 54 in the above technical solution is formed in a simple manner, thereby reducing the cost of the cleaning device 100 .

[0097] In some specific embodiments, the partition 5 and the diversion bracket 6 are integrally formed, which not only enhances the stability of the connection between the partition 5 and the separation bracket, but also reduces the cost of the cleaning device 100 .

[0098] Reference Figure 3, Fig.11 and Fig.12 In some embodiments, the host 1 is rotatably connected to the floor brush assembly 4 so that the host 1 has a vertical state and a lying state. In the lying state, the angle between the host 1 and the floor brush assembly 4 is 180 degrees, that is, the host 1 is completely lying down, and the overall height of the cleaning device 100 is the lowest at this time, so that the cleaning device 100 can extend the floor brush assembly 4 into low space areas such as the bottom of the sofa, the bottom of the bed, and the low cabinet area for cleaning. This effectively increases the usable range of the cleaning device 100 and improves the practicality of the cleaning device 100.

[0099] In some specific embodiments, when lying flat, the water filtering hole 51 is located at the bottom end of the partition 5 .

[0100] Through the above technical solution, the water filter hole 51 is located at the bottom end of the partition 5, that is, the water filter hole 51 is also located at the bottom of the first cavity 31 when the cleaning device 100 is lying flat, which is beneficial for the sewage in the first cavity 31 to enter the second cavity 32 through the water filter hole 51 when the cleaning device 100 is working in the lying state.

[0101] And under the action of the negative pressure difference between the first cavity 31 and the second cavity 32, the sewage in the first cavity 31 continuously flows into the second cavity 32, and it may even happen that the sewage level in the second cavity 32 is higher than the sewage level in the first cavity 31, thereby avoiding the possibility of a large amount of sewage in the second cavity 32, thereby reducing the probability of sewage entering the first fan 2 when the cleaning device 100 is in a lying state.

[0102] In some specific embodiments, the second cavity 32 has an expansion space 321. When in the lying state, the height of the expansion space 321 is lower than the height of the first cavity 31, so that when the cleaning device 100 is working in the lying state, the sewage in the first cavity 31 first flows into the expansion space 321, thereby increasing the space for accommodating the sewage in the second cavity 32 and extending the working time of the cleaning device 100 in the lying state.

[0103] Reference Figure 3 , Fig.10 and Fig.12 In some embodiments, the portion of the diversion bracket 6 extending into the second cavity 32 is also equipped with two water level detection probes 9, and the two water level detection probes 9 are arranged at intervals. When the sewage in the second cavity 32 contacts the exposed metal of the two water level detection probes 9 at the same time, a water full signal is triggered, and the cleaning device 100 stops cleaning.

[0104] The water level detection probe 9 extends along the length direction of the barrel body 33. When the main body is in a lying state, the horizontal detection probe 9 is also set to lie flat. When the sewage in the second cavity 32 contacts the exposed metal of the two water level detection probes 9 at the same time, a water full signal is triggered, and the cleaning device 100 stops cleaning to avoid the failure of the solid-liquid separation ability of the first cavity 31 due to excessive sewage in the second cavity 32, thereby reducing the probability of sewage entering the first fan 2 and ensuring the safety of the use of the cleaning device 100.
