DETAILED DESCRIPTION

[0038] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are for example only, and those skilled in the art may think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0039] like Fig.10 The figure shows a side view of a floor scrubber equipped with a recycling box of the present disclosure when working in a non-lying state, with one side of the cleaning brush 25 being the front side and the side of the handle 26 being the rear side. The user stands on one side of the handle 26 and pushes and pulls the cleaning brush 25 forward and backward for cleaning through the handle 26. Some floor scrubbers are provided with a power-assisting technical solution for the cleaning brush 25, that is, the user only needs to support the handle 26 and gently push it forward, and the cleaning brush 25 can move forward. When the same area needs to be cleaned repeatedly, the user needs to push and pull the cleaning brush 25 forward and backward for cleaning, and the recycling box is installed on the machine body 33, as shown in FIG. Fig. 9As shown by the arrows, the dirt sucked by the cleaning brush 25 enters the recovery box through the first air inlet pipe 8 for recovery, and the separated air is discharged by the exhaust device 12.

[0040] like Fig.11 The figure shows a side view of a floor scrubber equipped with a recycling box of the present invention when working in a lying state, that is, the cleaning brush 25 is rotatably connected to the body 33 so that the body 33 can be rotated to a lying position, so that the working state is almost parallel to the cleaned surface, and the height of the body 33 can be greatly reduced, so that the cleaning brush 25 can be extended into a narrow height cleaned area, such as the bottom of a bed or a sofa.

[0041] Since the entire body 33 is almost lying flat, the recycling box will lie flat from front to back, so that the dirt in the second chamber 6 lies flat to partially or completely submerge the connecting hole 13, and under the suction action of the second air suction port 14, the pressure of the second chamber 6 is lower than the pressure of the first chamber 5 so that the dirt entering the first chamber 5 continues to enter the second chamber 6 through the connecting hole 13. The specific structure of the recycling box is further described as follows.

[0042] like Figures 1 to 6 The figure shows a recycling box, comprising a recycling cup body 1 and a separation bracket 2 that can be axially sleeved together. The separation bracket 2 is provided with a top 3 and a partition 4 in order from top to bottom along the axial direction. After the recycling cup body 1 and the separation bracket 2 are axially sleeved together, the recycling cup body 1 is sealed by the top 3 and is divided by the partition 4 into a first chamber 5 and a second chamber 6 that are distributed up and down along the axial direction and isolated from each other. The first chamber 5 is located between the top 3 and the partition 4, and the second chamber 6 is located between the partition 4 and the inner bottom 7 of the recycling cup body 1. The recycling cup body 1 is provided with a first air inlet pipe 8 in the second chamber 6, and the partition 4 is provided with a connecting portion 9 that cooperates with the first air inlet pipe 8. The connecting portion 9 is provided with a first air inlet pipe 8. The part 9 is connected to the first chamber 5. When the recovery cup body 1 and the separation bracket 2 are axially sleeved together, the upper end of the first air inlet pipe 8 is connected to the connecting part 9, so that the dirt sucked by the first air inlet pipe 8 enters the first chamber 5 through the connecting part 9. When the recovery cup body 1 and the separation bracket 2 are axially separated to open the recovery cup body 1, the upper end of the first air inlet pipe 8 is separated from the connecting part 9; the first chamber 5 is provided with a first air suction port 10 on the front side close to the recovery cup body 1, the first air suction port 10 is higher than the sewage inlet port 11 in the first chamber 5 and / or the first air suction port 10 is separated from the sewage inlet port 11 in the first chamber 5, and the first air suction port 10 is used to be connected to the suction device 12.

[0043] A connecting hole 13 is provided on the rear side of the partition 4 located at the recovery cup body 1, and the dirt in the first chamber 5 enters the second chamber 6 through the connecting hole 13, and the sewage is recovered in the second chamber 6. The second chamber 6 is provided with a second air suction port 14 on the front side close to the recovery cup body 1. The second air suction port 14 is set higher than the sewage liquid level in the second chamber 6 and is used to communicate with the suction device 12.

[0044] The exhaust device 12 draws dirt into the second chamber 6 through the first exhaust port 10 and the second exhaust port 14 in sequence through the first air inlet pipe 8, the first chamber 5, and the connecting hole 13, and discharges the separated air through the first exhaust port 10 and the second exhaust port 14.

[0045] The recycling box can be arranged to lie flat from front to back. When the recycling box is lying flat, the dirt in the second chamber 6 lies horizontally to partially or completely submerge the connecting hole 13, and under the suction action of the second air suction port 14, the pressure of the second chamber 6 is lower than the pressure of the first chamber 5 so that the dirt entering the first chamber 5 continues to enter the second chamber 6 through the connecting hole 13.

[0046] Preferably, the connecting hole 13 is arranged as close to the rear side of the recovery cup body 1 as possible, or even directly on the rear side wall of the recovery cup body 1, so that when the recovery box is lying flat, the sewage in the second chamber 6 can completely submerge the connecting hole 13, which is conducive to quickly establishing a pressure difference between the first chamber 5 and the second chamber 6, and is conducive to establishing a larger pressure difference.

[0047] Of course, the connecting hole 13 can also be arranged forward, but it only needs to meet the requirement that it can be submerged to establish a pressure difference when the recycling box is lying flat.

[0048] In some embodiments, Figure 2 , 6 As shown in FIG. 9 , the upper end of the recovery cup body 1 is provided with an opening, and the separation bracket 2 is inserted / pulled out of the recovery cup body 1 through the opening. When inserted, the recovery cup body 1 and the separation bracket 2 are axially sleeved together. Figure 2 As shown, the separation bracket 2 is hollow in the circumference and has no complete and continuous circumferential side walls. Instead, the circumferential side walls of the first chamber 5 are provided by the inner circumferential walls of the recovery cup body 1, and the top 3 and the partition 4 of the separation bracket 2 provide the top and bottom surfaces of the first chamber 5. The circumferential side walls, top and bottom surfaces surround the first chamber 5, so that the separation bracket 2 can be easily rinsed and cleaned after being taken out.

[0049] In some embodiments, Figure 6As shown, the first air inlet pipe 8 is centrally arranged from the bottom 7 of the recovery cup body 1, so that the circumferential space surrounding the first air inlet pipe 8 of the recovery cup body 1 can be used to recover sewage, and has a large space, which is also the main part of the second chamber 6. Of course, the first air inlet pipe 8 can also be offset, and does not have to be centrally arranged, and can be adjusted according to the specific structural layout needs.

[0050] In some embodiments, Figure 3 , 4 As shown in FIG. 5 , the connection portion 9 is configured as a plug-in tube, and the upper end of the first air inlet pipe 8 is connected to the connection portion 9, which means that the upper end of the first air inlet pipe 8 is plugged into the plug-in tube, so that the connection is reliable and insertion / extraction is convenient. The plug-in tube is used as a sewage inlet 11 at the outlet of the first chamber 5.

[0051] Of course, the connecting portion 9 can also be other structures, such as a plug hole, through which the upper end of the first air inlet pipe 8 is inserted and exposed in the first chamber 5, that is, the upper end of the first air inlet pipe 8 is exposed in the first chamber 5, and at this time, the upper end outlet of the first air inlet pipe 8 serves as the sewage inlet 11.

[0052] In some embodiments, Figure 3 , 4 As shown in , 5 and 9 , the partition 4 is an L-shaped partition 4 , and the vertical portion 16 of the L-shaped partition 4 is located at the front side of the recovery cup body 1 , and a bypass flow channel 18 is formed between the vertical portion 16 and the front side portion 17 of the recovery cup body 1 , and the front side portion 17 of the recovery cup body 1 is provided with the second air suction port 14 .

[0053] In some embodiments, Figure 5 , 9 As shown, the vertical portion 16 is provided with a labyrinth flow channel 15. Thus, on the one hand, the labyrinth flow channel 15 is provided between the second air suction port 14 and the second chamber 6, which provides great convenience and is beneficial to production and manufacturing. On the other hand, it can greatly prevent sewage from entering the air suction device 12 through the second air suction port 14.

[0054] In some embodiments, Figure 2 , 5 As shown, it also includes a first sealing ring 19, which is arranged on both sides of the vertical portion 16. When the recovery cup body 1 and the separation bracket 2 are axially sleeved, the first sealing ring 19 is sealed against the inner wall of the recovery cup body 1. In this way, the sealing performance is improved.

[0055] In some embodiments, Figure 2 , 5As shown, the top 3 is provided with a circumferentially arranged second sealing ring 20, the partition 4 is provided with a circumferentially arranged third sealing ring 21, the third sealing ring 21 is provided with an opening on one side of the vertical portion 16 to form two ends, the two ends are respectively connected to the two lower ends of the first sealing ring 19, and the two upper ends of the first sealing ring 19 are connected to the second sealing ring 20. In this way, the sealing performance is improved.

[0056] In some embodiments, Figure 2 , 5 As shown, the second sealing ring 20, the first sealing ring 19, and the third sealing ring 21 are provided as an integrated sealing member, so as to facilitate production and manufacturing.

[0057] In some embodiments, Figure 3 , 4 As shown in Figures 9 and 10, a vertical baffle 22 is provided between the top 3 and the partition 4 of the separation bracket 2. The vertical baffle 22 divides the separation bracket 2 into a front part 23 and a rear part 24. The front part 23 is provided with a first air suction port 10, and the rear part 24 is provided with a sewage inlet 11. The air separated by the rear part 24 enters the front part 23 through both sides of the vertical baffle 22, and then enters the first air suction port 10 for discharge. In this way, the rear part 24 serves as a main separation chamber. When the gas and liquid are separated, it is not easy for the sewage to enter the suction device 12 through the first air suction port 10.

[0058] Furthermore, the vertical baffle 22 is provided with side baffles 32 on both sides of the sewage inlet 11. In this way, it is more difficult for sewage to enter the suction device 12 through the first suction port 10.

[0059] In some embodiments, Figure 3 , 4 As shown in FIG. 9 , the partition 4 is an L-shaped partition 4, the vertical portion 16 of the L-shaped partition 4 is located at the front side of the recovery cup body 1, the top of the vertical portion 16 is connected to the top 3, and the front portion 23 is formed between the vertical portion 16 and the vertical baffle 22. In this way, on the one hand, the structure is compact, and on the other hand, it is conducive to forming the front portion 23 with better sealing performance.

[0060] In some embodiments, Figure 3 , 4 As shown in FIG. 9 , the first air suction port 10 is arranged on the top 3 . In this way, on the one hand, it is beneficial to smooth air flow, and on the other hand, it is more difficult for sewage to enter the air suction device 12 through the first air suction port 10 .

[0061] In some embodiments, Figure 1 , 9 As shown, the top 3 is provided with a filter 27 , the first air suction port 10 is connected to the inlet of the filter 27 , and the first air suction port 10 is connected to the air suction device 12 via the filter 27 .

[0062] Preferably, Figure 1 , 9 As shown, the second air suction port 14 is arranged at the front side portion 17 of the recovery cup body 1, and the front side portion 17 is detachably connected to the bypass portion 28 so that the second air suction port 14 is connected to the air suction device 12 through the bypass portion 28. In this way, on the one hand, the second air suction port 14 will not occupy the top 3 space of the separation bracket 2, so that a larger filter 27 can be placed. On the other hand, a certain isolation is made between the first air suction port 10 and the second air suction port 14, that is, they are separately connected to the air suction device 12 through the filter 27, which is conducive to establishing a pressure difference more quickly.

[0063] Of course, the second air suction port 14 may also be arranged at other positions, such as the top 3 of the separation bracket 2 ; the second air suction port 14 may also be arranged to be connected to the air suction device 12 via the filter 27 .

[0064] In some embodiments, Fig. 9 As shown, the machine body 33 is provided with a bypass portion 28 at the second air suction port 14. When the recovery cup body 1 equipped with the separation bracket 2 is repeatedly disassembled / assembled from the machine body 33, the front side portion 17 is detachably connected to the bypass portion 28, which means that the front side portion 17 and the bypass portion 28 are detachably fitted. In this way, on the one hand, it is convenient for production and manufacturing, and on the other hand, it is convenient for the recovery cup body 1 and the separation bracket 2 to be repeatedly disassembled / assembled from the machine body 33, that is, it is convenient for the recovery box to be repeatedly disassembled / assembled from the machine body 33.

[0065] Preferably, Fig. 9 As shown, a fourth sealing ring 29 is provided between the bypass portion 28 and the front side portion 17. When the recovery cup body 1 is mounted on the machine body 33, the bypass portion 28 and the front side portion 17 are sealed and connected with the second air extraction port 14 through the fourth sealing ring 29. In this way, better sealing is achieved.

[0066] In some embodiments, Figure 2 As shown, a surge-proof baffle 30 is provided on the lower side of the partition 4, and the surge-proof baffle 30 is used to block the movement of sewage in the axial direction. In this way, when the floor scrubber is pushed and pulled back and forth in a flat state, the waves formed in the recovery cup body 1 can be blocked by the surge-proof baffle 30, thereby reducing the degree of waves.

[0067] Preferably, Figure 2 As shown, a filter basket 31 is connected to the lower side of the partition 4, and the filter basket 31 can be taken out / loaded from the recovery cup body 1 together with the separation bracket 2, and the bottom of the filter basket 31 serves as an anti-surge baffle 30. In this way, on the one hand, the filter basket 31 performs filtering and the fixed waste is trapped in the filter basket 31, so as to achieve better separation of sewage and solid waste. On the other hand, the bottom of the filter basket 31 serves as an anti-surge baffle 30, providing an anti-surge function, making the structure compact and multifunctional.
