Description

Technical Field

[0001] The utility model relates to the field of floor cleaning, in particular to a floor scrubber. Background Art

[0002] Existing floor scrubbers are mainly used to meet the cleaning needs of the floor. As users' demands for cleaning areas increase, such as being able to clean low space areas such as under beds, some floor scrubbers can form a lying structure to facilitate users to use floor scrubbers to clean low space areas such as under beds and sofas. However, the structure of existing floor scrubbers is prone to sewage backflow and damage to the fan during the lying process. This is mainly because the sewage tank structure of the existing floor scrubber cannot adapt well to the changes in the sewage collection and storage status, and cannot timely and effectively detect the sewage liquid level, resulting in sewage easily backflowing into the fan under the suction of the airflow, thereby causing damage to the fan. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems in the above-mentioned related technologies to a certain extent.

[0006] The sewage tank assembly includes a tank body and a cover body, at least a portion of the cover body being configured to be located in a sewage cavity within the tank body;

[0007] The sewage chamber is provided with a front accommodating chamber and a rear accommodating chamber, and a partition is provided between the front accommodating chamber and the rear accommodating chamber. When the rod body is in an upright structure or an inclined structure relative to the ground drag body, the partition is provided so that the front accommodating chamber and the rear accommodating chamber constitute mutually independent cavity structures in the front-to-back direction and constitute a structure distributed adjacently in the front-to-back direction.

[0008] The partition is provided with a through opening, which enables the front accommodating chamber and the rear accommodating chamber to form a structure that is interconnected;

[0009] The cover body is provided with an air flow port, which is arranged to be located in the front accommodating chamber to be in communication with the front accommodating chamber; the box body is provided with a sewage inlet, which is arranged to be located in the rear accommodating chamber to be in communication with the rear accommodating chamber;

[0010] The cover body is provided with a first electrode assembly, which is arranged to be located in the rear accommodating cavity. The first electrode assembly is used to detect the liquid level in the rear accommodating cavity at least when the rod body is in an upright structure or an inclined structure relative to the ground drag body;

[0011] A second electrode assembly is also provided on the cover body, and the second electrode assembly is arranged to be located in the front accommodating cavity. The second electrode assembly is at least used to detect the liquid level in the front accommodating cavity when the rod body is in a flat structure relative to the ground drag body.

[0012] In the aforementioned floor scrubber, the first electrode assembly includes a first electrode member and a second electrode member spaced apart from each other; the second electrode assembly includes a third electrode member and a fourth electrode member spaced apart from each other;

[0013] When the rod body is in an upright structure relative to the ground drag body, the first electrode member and the second electrode member are in a structure extending from top to bottom to detect the liquid level surface of the rear accommodating chamber in the up and down directions, and the third electrode member and the fourth electrode member are in a structure extending from front to back, and the end positions of the first electrode member and the second electrode member are arranged to be below the end positions of the third electrode member and the fourth electrode member.

[0014] In the aforementioned floor scrubber, when the rod body is in a lying structure relative to the mop body, the first electrode member and the second electrode member are in a structure extending from back to front in the front-to-back direction, and the third electrode member and the fourth electrode member are in a structure extending from top to bottom in the up-down direction to detect the liquid level surface of the front accommodating chamber in the up-down direction.

[0015] The aforementioned floor scrubber is arranged so that when the rod body is in an upright structure relative to the mop body, the end positions of the third and fourth electrode members are located above two-thirds of the height distance formed by the front accommodating cavity in the vertical direction.

[0016] The aforementioned floor scrubber is arranged so that the air flow opening is located above the end positions of the third and fourth pole members when the rod body is in an upright structure or an inclined structure relative to the mop body, and the air flow opening is arranged to be open toward the rear or downward direction.

[0017] In the aforementioned floor scrubber, when the rod body is in an upright structure relative to the mop body, the through opening is arranged below the center position of the height distance formed by the partition in the up and down directions, and the air flow port and the sewage inlet are arranged above the through opening.

[0018] In the aforementioned floor scrubber, when the rod body is in an upright position relative to the mop body, the vertical height distance from the through opening downward to the bottom wall of the front accommodating chamber is smaller than the vertical height distance from the through opening upward to the air flow opening;

[0019] Alternatively, when the rod body is in an upright structure relative to the ground drag body, the vertical height distance from the through opening downward to the bottom wall of the front accommodating cavity is smaller than the vertical height distance from the through opening upward to the end positions of the third pole piece and the fourth pole piece.

[0020] In the aforementioned floor scrubber, when the rod body is in a lying structure relative to the mop body, the end positions of the third electrode member and the fourth electrode member are set to be close to the upper surface of the partition and are not in contact with each other, and the air flow outlet is set above the end positions of the third electrode member and the fourth electrode member, and the vertical height distance from the end positions of the third electrode member and the fourth electrode member to the air flow outlet is set to be greater than the vertical height distance from the end positions of the third electrode member and the fourth electrode member to the upper surface of the partition.

[0021] The aforementioned floor scrubber is provided with a baffle in the front receiving chamber for blocking the surging sewage;

[0022] When the rod body is in an upright position relative to the ground drag body, the blocking portion is configured to extend from top to bottom in the vertical direction;

[0023] When the rod body is in a flat position relative to the ground drag body, the blocking portion is configured to extend from the back to the front in the front-to-back direction, and the blocking portion is located between the end position of the third pole piece or the fourth pole piece and the air flow opening in the top-to-bottom direction;

[0024] A return port is provided on the blocking portion. When the rod body is in a flat structure relative to the ground drag body, the projection area formed by the third electrode member and the fourth electrode member projected in the up and down directions does not overlap with the return port.

[0025] The aforementioned floor scrubber is provided with a partition portion that is arranged to be inclined from the upper end toward the lower end and toward the rear side when the rod body is in an upright structure relative to the floor mop body, so that when the rod body is in a lying structure relative to the floor mop body, the partition portion is arranged to be inclined from the rear end toward the front end and toward the lower side.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In this solution, the sewage chamber is provided with a front accommodating chamber and a rear accommodating chamber, which are independent cavities in the front and rear directions and are adjacent structures, so that the sewage tank can better adapt to the changes in the sewage collection and storage state in the sewage chamber, and the pole body can better collect and store sewage when it is in an upright structure, an inclined structure or a lying structure.

[0028] In this solution, when the rod body is in a lying structure, the sewage in the sewage chamber can be effectively concentrated in the rear accommodating chamber to be independently collected and stored, which can effectively prevent the sewage from surging upward and easily entering the air flow port, thereby preventing the sewage from backflowing and causing damage to the fan.

[0029] In this solution, when the rod body is in an upright structure or an inclined structure, the sewage can be collected and stored in the front accommodating chamber and the rear accommodating chamber. When the rod body is in an inclined structure, the sewage in the front accommodating chamber is relatively less, so the liquid level is relatively low, and the sewage in the rear accommodating chamber is relatively more, so the liquid level is relatively high, thereby effectively preventing the sewage in the front accommodating chamber from surging into the air flow outlet, thereby preventing the sewage from backflowing and causing damage to the fan.

[0030] In this solution, by setting up a first electrode assembly and a second electrode assembly, the first electrode assembly can detect the liquid level in the rear accommodating chamber, and the second electrode assembly can detect the liquid level in the front accommodating chamber, so as to better realize the timely and effective detection of the liquid level in the sewage chamber when the rod body is in an upright structure, an inclined structure or a lying structure, and prevent the problem of sewage backflow causing damage to the fan.

[0031] In this solution, when the rod body is in an upright structure or an inclined structure, the first electrode assembly and the second electrode assembly can achieve a dual detection effect of the liquid level at different height positions in the sewage chamber, thereby realizing timely and effective detection of the liquid level, and effectively preventing sewage from flowing back into the air flow outlet and causing damage to the fan.

[0032] In this solution, when the rod body is in a lying structure, the second electrode assembly switches from a structural state extending from front to back to a structural state extending from top to bottom. At this time, the second electrode assembly can better detect the liquid level of the front accommodating chamber in the up and down directions. At the same time, the rear accommodating chamber will give priority to collecting sewage and the front accommodating chamber will collect sewage only after the rear accommodating chamber is full of sewage. The second electrode assembly can timely and effectively detect the sewage liquid level in the front accommodating chamber, effectively preventing sewage from surging into the air flow outlet and causing damage to the fan.

[0033] In this solution, the structures and position distribution structures such as the sewage chamber, partition, air flow port, and through port can better adapt to changes in the sewage collection and storage state. When the sewage tank assembly is in an upright structure, an inclined structure, or a flat structure, it can better collect and store sewage as the structural state of the sewage tank assembly changes, and sewage is not easy to enter the air flow port, thereby improving the stability and reliability of sewage collection and improving the safety and reliability of the fan.

DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0042] Embodiment: The floor scrubber of the present invention is as follows: Figures 1 to 6 As shown in the structure, the floor scrubber is mainly used to achieve the cleaning effect of the ground, especially to better clean low space areas such as under the bed and sofa. At the same time, during the cleaning process, the sewage can be better collected and is not easy to flow back and cause damage to the fan, so that the overall reliability of the floor scrubber is higher.

[0043] The floor scrubber of this solution includes a mop body 1 and a rod body 2. The rod body 2 is configured to rotate and swing relative to the mop body 1. The user can apply external force by operating the rod body 2 to make the rod body 2 rotate and swing in the front and back directions relative to the mop body 1, so as to cooperate with the user's operation to clean different areas of the floor.

[0044] The floor scrubber further comprises a sewage tank assembly 3, which is mounted on the rod body 2 and is used to collect sewage, wherein the sewage tank assembly 3 comprises a box body 30 and a cover body 31, at least a portion of the cover body 31 is configured to be located in a sewage cavity 32 in the box body 30, and the cover body 31 is used to form a structure for opening and closing the upper end opening position of the sewage cavity 32, and the cover body 31 can be configured to be detachably mounted at the upper end opening position of the cover body 31, and a portion of the cover body 31 is configured to extend into the sewage cavity 32; wherein the sewage cavity 32 is provided with a front accommodating chamber 321 and a rear accommodating chamber 322, both of which can be used to collect and hold sewage, and a partition 302 is provided between the front accommodating chamber 321 and the rear accommodating chamber 322, and the partition is provided when the rod body 2 is in an upright structure or an inclined structure relative to the floor mopping body 1 302 makes the front accommodating chamber 321 and the rear accommodating chamber 322 constitute independent cavity structures in the front-to-back direction and constitute adjacent distribution structures in the front-to-back direction. The front accommodating chamber 321 is located at the front position and the rear accommodating chamber 322 is located at the rear position. The two are adjacently distributed in the front-to-back direction. A through opening 303 is provided on the partition 302. The through opening 303 makes the front accommodating chamber 321 and the rear accommodating chamber 322 constitute a mutually connected structure, so that the sewage in the rear accommodating chamber 322 can enter the front accommodating chamber 321 through the through opening 303. The structure and position distribution of the front accommodating chamber 321 and the rear accommodating chamber 322 can better adapt to the changes in the sewage collection and storage state in the sewage chamber 32, so that the rod body 2 can better collect and store sewage when it is in an upright structure, an inclined structure or a lying structure.

[0045] Among them, an air flow port 311 is provided on the cover body 31, and the air flow port 311 is used for the flow of air to be discharged outward, and the air flow port 311 is connected to the fan provided on the rod body 2 through a channel, and the air flow port 311 is arranged to be located in the front accommodating chamber 321 to be connected to the front accommodating chamber 321. A sewage inlet 301 is provided on the box body 30, and the sewage inlet 301 is arranged to be located in the rear accommodating chamber 322 to be connected to the rear accommodating chamber 322. When the floor scrubber is started, the sucked sewage enters the rear accommodating chamber through the sewage inlet 301 322, at this time, the sewage entering through the sewage inlet 301 flows into the rear accommodating chamber 322, and the inflowing sewage will be blocked by the partition 302 and will not directly splash or surge to the air flow outlet 311. Instead, the inflowing sewage will be collected in the rear accommodating chamber 322 and then enter the front accommodating chamber 321 through the through port 303. Although the sewage in the front accommodating chamber 321 will also be driven by the airflow, the degree of surge is smaller than that of the sewage flowing into the rear accommodating chamber 322 through the sewage inlet 301, and the sewage is not easy to enter the air flow outlet 311.

[0046] In this solution, a hollow and cylindrical sewage inlet pipe is provided in the rear accommodating chamber 322. The sewage inlet port 301 is located at the end of the sewage inlet pipe to communicate with the rear accommodating chamber 322. The head end of the sewage inlet pipe is an open structure to communicate with the sewage inlet channel on the mop body 1 so that the airflow drives the sewage into the sewage inlet pipe.

[0047] Optionally, the diameter of the through opening 303 is set to be larger than the diameter of the sewage inlet 301 , so that the airflow can better absorb sewage into the sewage chamber 32 .

[0048] Among them, for the structural part of detecting the liquid level of the sewage in the sewage chamber 32, a first electrode assembly 33 is provided on the cover body 31, and the first electrode assembly 33 is arranged to be located in the rear accommodating chamber 322. The first electrode assembly 33 is at least used to detect the liquid level in the rear accommodating chamber 322 when the rod body 2 is in an upright structure or an inclined structure relative to the drag body 1. When a certain amount of sewage is collected in the rear accommodating chamber 322, the liquid level of the sewage can be detected by the first electrode assembly 33 and a sewage signal can be triggered. At this time, the fan can be controlled to stop working to prevent sewage from entering the air flow port 311 and causing the fan to stop. damage; a second electrode assembly 34 is further provided on the cover body 31, and the second electrode assembly 34 is arranged to be located in the front accommodating chamber 321. The second electrode assembly 34 is at least used to detect the liquid level in the front accommodating chamber 321 when the rod body 2 is in a flat structure relative to the drag body 1. When the sewage in the rear accommodating chamber 322 is full and part of the sewage enters the sewage in the front accommodating chamber 321 and a certain amount is collected, the liquid level of the sewage can be detected by the second electrode assembly 34 and a sewage signal can be triggered. At this time, the fan can be controlled to stop working to prevent sewage from entering the air flow port 311 and causing damage to the fan;

[0049] Optionally, both the first electrode assembly 33 and the second electrode assembly 34 are electrically connected to the control module.

[0050] In this solution, since the sewage tank assembly 3 is installed on the rod body 2, when the rod body 2 is in an upright structure relative to the mop body 1, the sewage tank assembly 3 is correspondingly in an upright structure; when the rod body 2 is in an inclined structure relative to the mop body 1, the sewage tank assembly 3 is correspondingly in an inclined structure; when the rod body 2 is in a lying structure relative to the mop body 1, the sewage tank assembly 3 is correspondingly in a lying structure.

[0051] Optionally, when the rod body 2 is in an upright structure or an inclined structure, the rear accommodating chamber 322 is located on the rear side of the front accommodating chamber 321, and the rear accommodating chamber 322 is used to collect sewage, and the collected sewage will enter the front accommodating chamber 321 through the opening 303. In the process of collecting sewage, if the first electrode assembly 33 is triggered to detect a sewage signal, the fan can be controlled to stop working, which can better prevent sewage from entering the air flow port 311 and damaging the fan.

[0052] Optionally, when the rod body 2 is in a lying structure, the rear accommodating chamber 322 is located at the lower side of the front accommodating chamber 321 to preferentially collect sewage. At this time, if the first electrode assembly 33 is triggered to detect a sewage signal and the second electrode assembly 34 is not triggered, that is, no sewage signal is detected, the fan is controlled to continue working until the second electrode assembly 34 is triggered to detect a sewage signal, then the fan is controlled to stop working. This can also better prevent sewage from entering the air flow port 311 to damage the fan.

[0053] In terms of the specific structural part, the first electrode assembly 33 includes a first electrode member 331 and a second electrode member 332 spaced apart from each other, and the first electrode member 331 and the second electrode member 332 can be arranged to be spaced apart in the front-to-back direction or the left-to-right direction; the second electrode assembly 34 includes a third electrode member 341 and a fourth electrode member 342 spaced apart from each other, and the third electrode member 341 and the fourth electrode member 342 can be arranged to be spaced apart in the front-to-back direction or the left-to-right direction, and the liquid level detection effect can be achieved by the disconnection or passage between the first electrode member 331 and the second electrode member 332, and the disconnection or passage between the third electrode member 341 and the fourth electrode member 342.

[0054] Among them, when the rod body 2 is in an upright structure relative to the drag body 1, the first electrode member 331 and the second electrode member 332 are in a structure extending from top to bottom to detect the liquid level of the rear accommodating chamber 322 in the up and down directions. At this time, the first electrode assembly 33 detects the height of the liquid level in the rear accommodating chamber 322. The sewage is collected in the rear accommodating chamber 322 and contacts the first electrode assembly 33 after a certain amount of sewage is collected to trigger the detection of the sewage signal. The third electrode member 341 and the fourth electrode member 342 are in a structure extending from front to back. At this time, the sewage in the front accommodating chamber 321 is Water is not easy to contact the third electrode member 341 and the fourth electrode member 342, and is not easy to be contacted by sewage in the upper and lower directions. The end positions of the first electrode member 331 and the second electrode member 332 are set below the end positions of the third electrode member 341 and the fourth electrode member 342 to achieve that when the sewage collected in the sewage chamber 32 reaches a certain amount, the sewage will first contact the first electrode member 331 and the second electrode member 332, and at this time the third electrode member 341 and the fourth electrode member 342 will not be contacted by the sewage, so as to collect more sewage, and at the same time, the sewage is not easy to enter the air flow port 311.

[0055] In this solution, when the rod body 2 is in a lying structure relative to the ground drag body 1, the first electrode member 331 and the second electrode member 332 are in a structure extending from back to front in the front-to-back direction. At this time, the first electrode assembly 33 will be formed with the sewage in the rear accommodating chamber 322 to form a structure in the lateral direction, and the third electrode member 341 and the fourth electrode member 342 are in a structure extending from top to bottom in the up-down direction to detect the liquid level surface of the front accommodating chamber 321 in the up-down direction. At this time, the second electrode assembly 34 detects the height of the liquid level surface in the front accommodating chamber 321. The sewage is collected in the front accommodating chamber 321 and contacts the second electrode assembly 34 after a certain amount is collected to trigger the detection of the sewage signal.

[0056] In this solution, the structure and position of the first electrode assembly 33 are set so that when the rod body 2 is in the upright structure or the inclined structure, the floor scrubber cleans the ground and collects sewage. At this time, the first electrode assembly 33 can effectively detect the sewage liquid level in the rear accommodating chamber 322. When a certain amount of sewage is collected, the sewage will first contact the first electrode assembly 33 to trigger the detection of the sewage signal. When the sewage signal is triggered, it indicates that the sewage chamber 32 is full of sewage, and the fan is controlled to stop working. The user needs to manually dump the sewage from the sewage chamber 32.

[0057] In this solution, the structure and position setting of the second electrode assembly 34 enable the floor scrubber to clean the ground and collect sewage when the rod body 2 is in the lying structure. At this time, the second electrode assembly 34 can effectively detect the liquid level of the sewage in the front accommodating chamber 321. When a certain amount of sewage is collected, the sewage will first fill the rear accommodating chamber 322. Then the sewage will be collected in the front accommodating chamber 321 and will contact the second electrode assembly 34 after a certain amount of sewage is collected to trigger the detection of the sewage signal. When the sewage signal is triggered, it indicates that the sewage chamber 32 is full of sewage, and the fan is controlled to stop working. The user is required to manually dump the sewage from the sewage chamber 32.

[0058] Among them, when the liquid level of the sewage in the rear accommodating chamber 322 causes the first electrode member 331 and the second electrode member 332 to be contacted by the sewage, a passage is formed at this time, so that the sewage contacts the first electrode member 331 and the second electrode member 332, so that the first electrode assembly 33 is triggered to form a sewage signal. At this time, the sewage signal can indicate that the sewage liquid level in the rear accommodating chamber 322 is high, and the user is required to dump the sewage in the sewage chamber 32. At this time, the fan can be controlled to stop working to prevent sewage from entering the air flow port 311 and damaging the fan.

[0059] Among them, when the liquid level of the sewage in the front accommodating chamber 321 causes the third electrode member 341 and the fourth electrode member 342 to be contacted by the sewage, a passage is formed at this time, so that the sewage contacts the third electrode member 341 and the fourth electrode member 342, so that the second electrode assembly 34 is triggered to form a sewage signal. At this time, the sewage signal can indicate that the sewage liquid level in the front accommodating chamber 321 is high, and the user is required to dump the sewage in the sewage chamber 32. At this time, the fan can be controlled to stop working to prevent sewage from entering the air flow outlet 311 and damaging the fan.

[0060] Among them, when the first electrode member 331 and the second electrode member 332 are not contacted by the sewage liquid level surface, the first electrode member 331 and the second electrode member 332 are open circuit, so that the first electrode assembly 33 will not be triggered; when the third electrode member 341 and the fourth electrode member 342 are not contacted by the sewage liquid level surface, the third electrode member 341 and the fourth electrode member 342 are open circuit, so that the second electrode assembly 34 will not be triggered.

[0061] Among them, it can be understood that when the rod body 2 is in a lying structure relative to the mop body 1, the user can hold the rod body 2 to clean low ground areas such as under the bed, under the table, and under the sofa, and collect sewage during the cleaning process.

[0062] It is understandable that when the rod body 2 is in an upright or inclined structure relative to the mop body 1, the user can clean the open floor area indoors by holding the rod body 2 and collect sewage during the cleaning process.

[0063] In order to further prevent the sewage from surging back and flowing into the air flow port 311 and causing damage to the fan, in this solution, when the rod body 2 is in an upright structure relative to the drag body 1, the end positions of the third electrode member 341 and the fourth electrode member 342 are located above the position of two-thirds of the height distance formed by the front accommodating chamber 321 in the vertical direction, so that the position of the lower part of the front accommodating chamber 321 is used to collect and hold sewage, and at the same time, the sewage in the rear accommodating chamber 322 can effectively enter the front accommodating chamber 321 to collect more sewage, and when the rod body 2 is in an inclined structure, as the amount of sewage collected increases during the sewage collection process, the first electrode assembly 33 will eventually be contacted by the sewage to trigger the detection of the sewage signal; the position distribution setting of the end positions of the third electrode member 341 and the fourth electrode member 342 ensures that there is sufficient space in the front accommodating chamber 321 to collect and hold sewage, and can prevent the sewage from surging back and flowing into the air flow port 311 and causing damage to the fan.

[0064] Preferably, when the rod body 2 is in an upright structure relative to the ground mop body 1, the end positions of the third electrode member 341 and the fourth electrode member 342 are located below a quarter of the height distance formed by the front accommodating cavity 321 in the vertical direction, so that sewage is not easy to enter the air flow outlet 311 upward.

[0065] In order to further prevent sewage from surging and flowing back into the air flow port 311 and causing damage to the fan, in this solution, when the rod body 2 is in an upright structure or an inclined structure relative to the drag body 1, the air flow port 311 is located above the end position of the third pole member 341 and the fourth pole member 342, and the air flow port 311 is set to be an open structure facing the rear side or the lower side. The air flow port 311 is above the end position of the third pole member 341 and the fourth pole member 342 for the entry of air, and the air flow will drive part of the sewage in the front accommodating chamber 321. When water surges and a certain amount of sewage is collected in the front accommodating chamber 321, the surging sewage will contact the end positions of the third electrode member 341 and the fourth electrode member 342, so that the second electrode assembly 34 is triggered to detect the sewage signal. After the sewage signal is triggered, the fan is controlled to stop working, so the surging sewage will not continue to surge into the air flow port 311, and it is not easy to cause damage to the fan; the open structure of the air flow port 311 enables the air flow to effectively enter from the front accommodating chamber 321 and finally be discharged to the outside of the floor scrubber.

[0066] The bottom wall of the front accommodating chamber 321 is provided with a relatively small distance from the bottom wall of the front accommodating chamber 321 so that the sewage in the rear accommodating chamber 322 can be discharged. When the sewage in the rear accommodating chamber 322 is collected to a certain amount, the sewage will enter the front accommodating chamber 321 through the through port 303 below the sewage inlet 301, so that the sewage passing through the sewage inlet 301 will not flow directly into the front accommodating chamber 321, but will be collected and concentrated in the rear accommodating chamber 322 first. This can effectively prevent the sewage from being concentrated in the front accommodating chamber 321 and surging back into the air flow port 311 to cause damage to the fan.

[0067] In order to further prevent sewage from surging and flowing back into the air flow outlet 311 and causing damage to the fan, when the rod body 2 is in an upright structure relative to the ground drag body 1, the vertical height distance from the through hole 303 to the bottom wall of the front accommodating chamber 321 is set to be smaller than the vertical height distance from the through hole 303 to the air flow outlet 311. In this way, there is a relatively large spacing distance from the through hole 303 to the air flow outlet 311. When sewage at the position of the through hole 303 surges, it is not easy for the sewage to enter the air flow outlet 311 upward. The relatively small spacing distance from the through hole 303 to the bottom wall of the front accommodating chamber 321 ensures that the sewage in the rear accommodating chamber 322 can enter the front accommodating chamber 321 through the through hole 303 in time.

[0068] Alternatively, in order to further prevent sewage from surging and flowing back into the air flow port 311 and causing damage to the fan, when the rod body 2 is in an upright structure relative to the ground drag body 1, the vertical height distance from the through-port 303 downward to the bottom wall of the front accommodating chamber 321 is set to be smaller than the vertical height distance from the through-port 303 upward to the end position of the third electrode member 341 and the end position of the fourth electrode member 342. In this way, there is a relatively large spacing distance between the through-port 303 upward to the end position of the third electrode member 341 and the end position of the fourth electrode member 342. When the through-port When the sewage at position 303 surges, it is not easy for the sewage to flow upward to the air flow outlet 311. When a certain amount of sewage is collected in the front accommodating chamber 321, the sewage can first contact the end positions of the third electrode member 341 and the fourth electrode member 342 when surging, and will not surge to the air flow outlet 311, so that there is a relatively small spacing distance from the through port 303 to the bottom wall of the front accommodating chamber 321, so that the sewage in the rear accommodating chamber 322 can enter the front accommodating chamber 321 through the through port 303 in time.

[0069] The top of the drain plug 31 is provided with a plurality of drain plugs 320, 321 and a plurality of drain plugs 322, 323 and 324, which are provided with a plurality of drain plugs 320, 321 and a plurality of drain plugs 322, 323 and a plurality of drain plugs 324, 324 and a plurality of drain plugs 326. The vertical height distance of the flow outlet 311 is greater than the vertical height distance downward to the upper surface of the partition 302. In this way, even if part of the sewage in the front accommodating chamber 321 surges under the drive of the airflow, it is not easy to enter the airflow outlet 311. When the sewage collected and contained in the front accommodating chamber 321 surges, the surging sewage will first contact the end positions of the third electrode member 341 and the fourth electrode member 342, so that the second electrode assembly 34 is formed into a connecting path to trigger the detection of the sewage signal. At this time, the fan can be controlled to stop working in time, so that the surging sewage is not easy to enter the airflow outlet 311. In this process, even if the sewage surges, it will first contact the third electrode member 341 and the fourth electrode member 342 to enable the second electrode assembly 34 to detect the sewage signal, and then stop the generation of the airflow in time, so that the sewage will not continue to be driven by the airflow, thereby effectively preventing the sewage from surging back into the airflow outlet 311 and causing damage to the fan.

[0070] In order to further prevent the sewage from surging and flowing back into the air flow port 311 and causing damage to the fan, in this solution, a baffle 312 is provided in the front accommodating chamber 321 to block the surging sewage. When the floor scrubber is working, when the suction of the air flow is generated to absorb and collect the sewage into the sewage chamber 32, part of the sewage will surge in the front accommodating chamber 321 under the drive of the air flow. By providing the baffle 312, the surging sewage will be blocked by the baffle 312 so that the sewage cannot flow upward. Under the obstruction of the baffle 312, the sewage will fall back and enter the front accommodating chamber 321 and finally enter the rear accommodating chamber 322 through the through port 303. This can prevent the surging sewage from entering the air flow port 311 upward due to the drive of the air flow. The specific structural part When the rod body 2 is in an upright position relative to the mop body 1, the blocking portion 312 is configured to extend from top to bottom in the vertical direction, and the blocking portion 312 can be set on the cover body 31 to form a convex structure extending toward the sewage chamber 32. When the rod body 2 is in an upright structure relative to the mop body 1, the blocking portion 312 can form a blocking structure for the sewage surging at the position of the through port 303. When the rod body 2 is in a flat structure relative to the mop body 1, the blocking portion 312 is configured to extend from back to front in the front-to-back direction, and the blocking portion 312 is located between the end position of the third electrode member 341 or the fourth electrode member 342 and the air flow port 311 in the vertical direction. The structure of the blocking portion 312 can be realized to form a structure to block the sewage from flowing upward The turbulent flow occurs, and when the airflow enters the airflow port 311, it drives part of the sewage to turbulently, and the turbulent sewage will be blocked by the blocking portion 312 to form a fallback, so that the sewage will not surge and flow directly into the airflow port 311, but will fall back into the front accommodating chamber 321 after being blocked by the blocking portion 312. At the same time, a return port 3121 is provided on the blocking portion 312. When the rod body 2 is in a flat structure relative to the drag body 1, the projection area formed by the projection of the third electrode member 341 and the fourth electrode member 342 in the upper and lower directions does not overlap with the return port 3121. Through the setting of the return port 3121, even if some sewage turbulences and passes through the end position of the blocking portion 312 in the extending direction and enters the surface of the blocking portion 312 The sewage on the upper surface of the blocking portion 312 will also flow back into the front receiving chamber 321 through the reflux port 3121. The non-overlapping structure prevents the sewage on the upper surface of the blocking portion 312 from flowing back from the third electrode member 341 and the fourth electrode member 342. This can prevent the second electrode assembly 34 from making a false detection. The third electrode member 341 and the fourth electrode member 342 will be connected as a pathway only when they are both contacted by the sewage in the front receiving chamber 321 to trigger the detection of the sewage signal. The sewage signal will not be detected due to the connection between the third electrode member 341 and the fourth electrode member 342 caused by the sewage backflow on the upper surface of the blocking portion 312, thereby improving the reliability and stability of the second electrode assembly 34 in detecting the sewage liquid level in the front receiving chamber 321.

[0071] In this solution, in order to further improve the sewage collection and concentration of the rod body 2 in the flat structure, the main arrangement is that when the rod body 2 is in an upright structure relative to the mop body 1, the partition 302 is configured as an inclined structure that is inclined from the upper end toward the lower end and toward the rear side, so that when the rod body 2 is in a flat structure relative to the mop body 1, the partition 302 is configured as an inclined structure that is inclined from the rear end toward the front end and toward the lower side. The inclined structure of the partition 302 allows the sewage that surges into the front accommodating chamber 321 to flow toward the vicinity of the through hole 303 under the inclined structure and flow back to The sewage is collected in the rear accommodating chamber 322, so that the sewage is collected and concentrated in the rear accommodating chamber 322 first. When the rear accommodating chamber 322 is full of sewage, the sewage will be collected in the front accommodating chamber 321. The inclined structure of the partition 302 can better guide the sewage to be collected and concentrated in the rear accommodating chamber 322, so that the sewage can flow along the inclined direction on the inclined structure, that is, the upper surface of the partition 302, and flow to the position of the port 303 to flow back and forth into the rear accommodating chamber 322, thereby effectively lifting the sewage tank. Under the lying structure, the sewage can be better collected and concentrated in the rear accommodating chamber 322.

[0072] Optionally, a through opening 303 is also provided at the end position along the inclined direction of the partition 302. The through opening 303 penetrates the partition 302 so that the front accommodating chamber 321 and the rear accommodating chamber 322 are connected. The sewage in the front accommodating chamber 321 can effectively flow in the inclined direction to the through opening 303 at the end position of the partition 302 and then flow back into the rear accommodating chamber 322 for collection and concentration.

[0073] In this solution, the sewage tank assembly 3 can be arranged to be detachably mounted on the rod body 2, so that the user can conveniently install the sewage tank assembly 3 in place or disassemble it for maintenance.

[0074] In this solution, a clean water tank is provided on the rod body 2 or the mop body 1. The clean water tank supplies clean water to the roller on the mop body 1 through a water pump, so that the roller is in a wet structure to clean the floor. In the process of cleaning the floor, the sewage formed on the roller is scraped out and separated by the scraping member and finally collected into the sewage chamber 32. In this process, the fan works to generate the suction force of the airflow so that the sewage is sucked and collected into the sewage chamber 32. This part is the existing technology and will not be described in detail here.

[0075] In this program Figures 1 to 6 , the handle portion on the rod body 2 is not shown, and the entire mop body 1 and a portion at the lower end region of the rod body 2 are mainly shown.

[0076] Anything not mentioned in this plan can be achieved by adopting or drawing on existing technologies.

[0077] Working principle: The floor scrubber of this solution can clean the floor area, wherein the floor area can be an open floor area or a low floor area such as the bottom of a bed or a sofa. Specifically, when the rod body 2 of the floor scrubber is in an upright or inclined structure relative to the mop body 1, it can clean the open floor area. When the rod body 2 is in a flat structure relative to the mop body 1, it can clean the low floor area. In this process, the front accommodating chamber 321 and the rear accommodating chamber 322 are set by the sewage chamber 32 to better adapt to the rod body 2. The position state of the rod body 2 can better adapt to the state of collecting and storing sewage in the sewage chamber 32, and the first electrode assembly 33 is used to detect the liquid level of the sewage in the rear accommodating chamber 322 when the rod body 2 is in an upright or inclined structure relative to the mop body 1, that is, to detect the liquid level of the sewage, and the second electrode assembly 34 is used to detect the liquid level of the sewage in the front accommodating chamber 321 when the rod body 2 is in a lying structure relative to the mop body 1, so that the liquid level of the sewage can be detected in time and effectively, which can effectively prevent the problem of damage to the fan caused by backflow of sewage.
