Description

Technical Field

[0001] The present invention relates to the technical field of floor scrubbers, and in particular to an automatic water-adding and sewage-discharging device used on a floor scrubber. Background Art

[0002] Environmental sanitation is an important factor affecting the quality of life. Therefore, with the continuous improvement of people's requirements for quality of life, the corresponding requirements for environmental sanitation are also getting higher and higher. However, the work pressure of modern people is increasing day by day, and they are in urgent need of being liberated from the heavy cleaning work. Therefore, many ground cleaning equipment have appeared to improve environmental sanitation. Commonly used ones are vacuum cleaners, automatic mops, sweepers and floor washers. Floor washers are a kind of equipment used to clean the ground. The current floor washers have been developed to have relatively complete functions. They are mainly divided into semi-automatic floor washers, fully automatic floor washers, hand-push floor washers and driving floor washers. However, the working principles of each floor washer are basically the same. They all spray clean water and detergent on the ground. While cleaning, they can also suck the sewage back into the sewage tank in the floor washer to complete the cleaning process.

[0003] Common floor scrubbers on the market are generally equipped with a base for charging, cleaning and other auxiliary actions. The conventional base is provided with a slot on the top. The user needs to lift the used floor scrubber as a whole to place the floor scrubber in the base. This method may cause the hair, water droplets and other residues remaining on the floor scrubber to fall during the lifting process, thereby dirtying the user's shoes or the ground, which is not conducive to use. If the base is set to be a push-in type with an overall box shape, although it solves the problem of hair, water droplets and other residues falling, the floor scrubber is easy to slide out of the base, which is not conducive to the base to clean the floor scrubber. In addition, the common floor scrubbers on the market generally set the sewage tank and the clean water tank on the handle of the floor scrubber body. After use, the sewage tank must be removed for cleaning, and the clean water tank must be removed for water. The whole process is cumbersome, and in the process, people's hands and clothes may be dirty, affecting people's user experience, which is not conducive to people's daily use. Summary of the invention

[0004] In view of the above-mentioned deficiencies, the purpose of the present invention is to provide an automatic water-adding and sewage-discharging device for a floor scrubber, which locks the floor scrubber body after the floor scrubber body is pushed into the base to prevent the floor scrubber from slipping, and can automatically discharge the sewage tank in the floor scrubber body and add water to the clean water tank in the floor scrubber body, and automatically stops adding water when the water is full.

[0049] Please refer to Figures 1 to 18 The embodiment of the present invention provides an automatic water-adding and sewage-discharging device for a floor scrubber, comprising a floor scrubber body 01 and a base 02 in which the floor scrubber body 01 is housed, a sewage tank 04 and a clean water tank 03 are arranged at the lower part of the floor scrubber body 01, and further comprising a locking mechanism 05 arranged on the base 02, a sewage-discharging mechanism 06 arranged between the base 02 and the sewage tank 04, and a water-adding mechanism 07 arranged between the base 02 and the clean water tank 03, the locking mechanism 05 comprising an awakening component 051 arranged on the floor scrubber body 01 and the base 02, and a fixing component 052 arranged on the base 02, the fixing component 052 comprising a locking driving mechanism arranged in the base 02 A motor 0521, a locking drive gear 0522 arranged on the output shaft of the locking drive motor 0521, a locking limit guide plate 0523 arranged in the base 02 and located above the locking drive motor 0521, a locking rotation drive plate 0524 whose lower end is meshed with the locking drive gear 0522 and rotates on the locking limit guide plate 0523, and clamping plates 0525 respectively arranged in both sides of the base 02 and connected to the locking rotation drive plate 0524, wherein a locking fixing column 05251 extending toward the direction of the scrubber body 01 is formed on the clamping plate 0525, and locking fixing grooves 011 for the locking fixing column 05251 to be placed are respectively formed on both sides of the scrubber body 01.

[0050] By configuring the automatic water adding device to include a locking mechanism 05 arranged on the base 02, a sewage discharge mechanism 06 arranged between the base 02 and the sewage tank 04, and a water adding mechanism 07 arranged between the base 02 and the clean water tank 03, when the floor scrubber body 01 is placed in the base 02, the locking mechanism 05 fixes the floor scrubber body 01 in the base 02 to prevent the floor scrubber body 01 from shifting or falling off during the process of sewage discharge, water addition, charging, etc., resulting in the inability to discharge sewage, add water, charge, etc. The user can start the sewage discharge mechanism 06 and / or the water filling mechanism 07 through the remote control or the buttons on the base 02. The drainage mechanism automatically discharges sewage from the sewage tank 04 in the floor scrubber body 01, and the water filling mechanism 07 transfers clean water to the clean water tank 03. When the water in the clean water tank 03 reaches a certain level, the water filling is automatically stopped. There is no need for people to manually disassemble the sewage tank 04 for cleaning, nor is there any need to disassemble the clean water tank 03 for filling. It can also be completed while waiting for charging, which saves time and effort, does not dirty the user, and effectively improves the user's experience of using the floor scrubber.

[0051] The locking mechanism 05 is configured to include a wake-up component 051 disposed on the floor scrubber body 01 and the base 02, and a fixing component 052 disposed on the base 02, wherein the fixing component 052 includes a locking drive motor 0521 disposed in the base 02, a locking drive gear 0522 disposed on the output shaft of the locking drive motor 0521, and a locking limit guide plate 0523 disposed in the base 02 and located above the locking drive motor 0521. , a locking rotating drive plate 0524 whose lower end is meshed with the locking drive gear 0522 and rotates on the locking limit guide plate 0523, and clamping plates 0525 respectively arranged on both sides of the base 02 and connected to the locking rotating drive plate 0524, the clamping plate 0525 is formed with a locking fixing column 05251 extending toward the direction of the scrubber body 01, and locking fixing grooves 011 for the locking fixing column 05251 to be placed are respectively formed on both sides of the scrubber body 01. When the user wants to place the floor scrubber body 01 into the base 02, he only needs to push the floor scrubber body 01 into the base 02. After the awakening component 051 senses the placement of the floor scrubber body 01, it controls the locking drive motor 0521 therein to start, driving the locking drive gear 0522 set thereon to drive the locking rotating drive plate 0524 meshed thereon to rotate on the locking limit guide plate 0523, so that the two sets of clamping plates 0525 connected to the locking rotating drive plate 0524 are tightened toward the direction of the floor scrubber body 01 under the drive of the locking rotating drive plate 0524, so that the locking fixing column 05251 thereon is placed in the locking fixing groove 011, and the floor scrubber body 01 cannot be separated from the base 02 without the application of external force, thereby effectively ensuring that the base 02 cleans, charges, and other actions on the floor scrubber body 01. It has a high degree of automation and a simple structure, is conducive to people's daily use, and effectively improves people's user experience.

[0052] Regarding the specific structural setting of the locking rotation drive plate 0524, as shown in FIG. Figures 4 to 8As shown, the lower end of the locking rotation driving plate 0524 is formed with a locking driven gear 05241 meshed with the locking driving gear 0522, and the two sides of the locking rotation driving plate 0524 are formed with locking driving columns 05242 extending upward to pass through the clamping plate 0525. The locking driven gear 05241 is meshed with the locking driving gear 0522, so that the locking driving motor 0521 drives the locking rotation driving plate 0524 to rotate on the locking limit guide plate 0523, and the locking driving column 05242 passes through the clamping plate 0525, so that the locking rotation driving plate 0524 simultaneously drives the clamping plate 0525 to shrink toward the washing machine body 01, thereby clamping the washing machine body 01 and achieving the purpose of locking the washing machine body 01. The whole process is simple and convenient in structure, does not require manpower, and is conducive to the coordination between various components.

[0053] Preferably, Figures 4 to 8 As shown, the diameter of the locking driven gear 05241 is larger than the diameter of the locking driving gear 0522. By using a smaller gear to drive a larger gear, the rotation speed of the locking rotating drive plate 0524 is adjusted while concentrating the torque of the gear transmission, thereby improving the stable power output and ensuring the service life of the locking mechanism 05.

[0054] Regarding the specific structural setting of the locking limit guide plate 0523, as shown in FIG. Figures 5 to 8 As shown, a locking rotation limiting groove 05231 is formed in the middle of the locking limiting guide plate 0523 for the locking rotation driving plate 0524 to rotate, and a gear clearance hole 05232 is provided in the middle of the locking rotation limiting groove 05231 for the locking driven gear 05241 to pass through and mesh with the locking driving gear 0522. When the locking rotation driving plate 0524 is driven by the locking driving motor 0521, it rotates in the locking rotation limiting groove 05231, thereby effectively preventing the locking rotation driving plate 0524 from falling off or shifting during the driving process, and effectively ensuring the normal operation of the locking mechanism 05. By opening a gear clearance hole 05232 in the middle of the locking rotation limit groove 05231, while providing space for the locking rotation drive plate 0524 to be installed and operated, the locking rotation drive plate 0524 is also effectively restricted, so that the axial position of the locking rotation drive plate 0524 is fixed, thereby effectively preventing the locking rotation drive plate 0524 from falling off or shifting during the driving process, and effectively ensuring the normal operation of the locking mechanism 05.

[0055] Preferably, Figures 6 to 8As shown, in order to enable the locking rotation drive plate 0524 to better drive the clamping plate 0525, the two sides of the locking rotation limit groove 05231 are respectively elliptical structures extending in opposite directions, and the two sides of the locking rotation drive plate 0524 are formed with eccentric vertex angles 05243 matching the elliptical structure. The structure of the ellipse and the eccentric vertex angle 05243 is guiding, which effectively improves the efficiency of the locking rotation drive plate 0524 rotating on the locking limit guide plate 0523, and also better limits the locking rotation drive plate 0524, so that its rotation is more in line with the law of natural rotation, making it easier to rotate, while improving the accuracy of rotation, further improving the locking efficiency of the locking mechanism 05.

[0056] Regarding the specific structural setting of the clamping plate 0525, as shown in FIG. Figures 5 to 8 As shown, the clamping plate 0525 is L-shaped as a whole, and the locking fixing column 05251 is formed on the short side of the clamping plate 0525 and extends toward the direction of the scrubber body 01. A clamping drive plate 05252 is formed on the long side of the clamping plate 0525, and a clamping drive groove 05253 is formed on the clamping drive plate 05252, which is perpendicular to the direction of the clamping plate 0525 and for the locking drive column 05242 to move and drive it. By setting the clamping drive plate 05252 and the clamping drive groove 05253 to a structure perpendicular to the clamping plate 0525, while the locking drive column 05242 moves in the clamping drive groove 05253 and drives it, its movement trajectory is more in line with the law of arc rotation, so that the locking rotation drive plate 0524 can drive the clamping plate 0525 more easily and accurately, effectively improving the locking efficiency of the locking mechanism 05.

[0057] Preferably, Figures 6 to 8 As shown, at least one clamping limit plate 05233 extending upward to limit the clamping plate 0525 is formed on the locking limit guide plate 0523. The clamping limit plate 05233 is arranged on the side of the clamping plate 0525, and the number and position of the clamping limit plate 05233 can be set according to the structure of the clamping plate 0525 and its moving trajectory, so no specific restrictions are made in this embodiment. By arranging the clamping limit plate 05233 on the locking limit guide plate 0523, the clamping plate 0525 is guided by the clamping limit plate 05233 during the movement, thereby limiting and guiding the clamping plate 0525, making the movement of the clamping plate 0525 easier and more accurate, and effectively improving the locking efficiency of the locking mechanism 05.

[0058] Preferably, Figures 6 to 8As shown, at least one limit screw passes through the locking limit guide plate 0523, and at least one clamping limit groove 05254 is formed on the clamping plate 0525, which extends laterally and is used for radial movement and limiting of the limit screw. As a result, when the clamping plate 0525 is moving, the clamping limit groove 05254 moves relative to the limit screw, and the stroke is limited by the limit screw, thereby effectively preventing the clamping plate 0525 from shifting during movement, making the movement of the clamping plate 0525 easier and more precise, and effectively improving the locking efficiency of the locking mechanism 05.

[0059] For the specific structural setting of the awakening component 051, as shown in FIG. Figures 5 to 9 As shown, the awakening component 051 includes at least one Hall element 0511 arranged in the base 02, and at least one magnet 0512 arranged in the bottom of the scrubber body 01. When the scrubber body 01 is placed in the base 02, the Hall element 0511 on the base 02 detects the approach of the magnet 0512, thereby triggering the fixing mechanism in the base 02 to lock the scrubber body 01. The whole process is highly automated and does not require human participation. In addition, the Hall element and the magnet 0512 are precisely matched, which effectively improves the locking efficiency of the locking mechanism 05.

[0060] In order to make it easier to place the scrubber body 01 into the base 02, Figure 1 to Figure 2 As shown, a push slope 021 is formed at the front end of the base 02, and the slope is arranged at the front end to facilitate the pushing in of the scrubber body 01, which is simple and convenient, and there is no need to lift the scrubber, thus avoiding the falling of hair, water droplets and other residues, and effectively improving people's user experience.

[0061] Regarding the specific structural setting of the sewage discharge mechanism 06, Figures 10 to 13As shown, the sewage discharge mechanism 06 includes a sewage discharge drive motor 061 arranged in the base 02, a sewage discharge drive gear 062 arranged on the output shaft of the sewage discharge drive motor 061, a sewage discharge connecting pipe 063 connected to the clamping plate 0525 on the side away from the locking drive motor 0521 and extending obliquely toward one end of the sewage tank 04 and extending into the sewage tank 04, a sewage discharge pipe 064 connected to the sewage discharge connecting pipe 063 and extending outward, and a sewage switch top opening member 065 arranged in the sewage discharge connecting pipe 063 and the upper end protruding from the sewage discharge connecting pipe 063 and meshing with the sewage discharge drive gear 062. A sewage discharge port 041 and a sewage discharge switch assembly 042 for blocking and sealing the sewage discharge port 041 are arranged on the lower part of one side of the sewage tank 04 opposite to the sewage discharge connecting pipe 063. After the floor scrubber body 01 is placed in the base 02, the user can start the sewage drive motor 061 through the remote control or the button on the base 02. After the sewage drive motor 061 is started, it drives the sewage drive gear 062 set on its output shaft to rotate, so that the sewage switch push-opening member 065 engaged with the sewage drive gear 062 moves toward the sewage switch assembly 042, and pushes the sewage switch assembly 042 upward, so that the sewage in the sewage tank 04 flows into the sewage connection pipe 063 from the sewage outlet 041 at the bottom of the sewage tank 04 under the action of gravity, and then enters the sewage pipe 064 and flows out to the outside, completing the entire sewage treatment. The whole process is simple and convenient. The sewage tank 04 in the floor scrubber body 01 can be drained while the floor scrubber body 01 is placed in the base 02. There is no need to disassemble the sewage tank 04 for cleaning. The sewage can be drained while charging and other work is in progress, which saves time and effort, does not dirty the user, and effectively improves the user's experience of using the floor scrubber.

[0062] Preferably, Fig.12 As shown, the sewage discharge mechanism 06 also includes a micro switch 066 disposed on the clamping plate 0525. When the clamping plate 0525 is retracted toward the scrubber body 01, the micro switch 066 moves with the clamping plate 0525 and abuts against the base 02, that is, abuts against the limit box 071 described below, to achieve triggering. The triggered micro switch 066 controls the sewage discharge drive motor 061 to start and start the sewage discharge step. By arranging a micro switch 066 on the clamping plate 0525, the micro switch 066 can be triggered by following the clamping plate 0525, and the activation accuracy is higher, which can effectively save energy and effectively improve the user experience of using the scrubber.

[0063] Regarding the specific structural setting of the sewage switch top opening member 065, as shown in FIG. Figures 10 to 13As shown, a driving rack 0651 is formed at the upper end of the sewage switch top opening member 065, and a plurality of teeth meshing with the driving gear are formed at the upper portion of the driving rack 0651, and a lifting portion 0652 extending toward the sewage tank 04 is formed at the lower portion of the sewage switch top opening member 065.

[0064] Regarding the specific structural setting of the sewage switch assembly 042, as shown in FIG. Figures 10 to 13 As shown, the sewage switch assembly 042 includes a sewage switch fixing plate 0421 disposed on the inner wall of the upper end of the sewage tank 04, a sewage discharge elastic member 0422 fixed at one end to the sewage switch fixing plate 0421, and a sewage discharge pressing member 0423 disposed at the other end of the sewage discharge elastic member 0422, and the sewage discharge pressing member 0423 seals the sewage outlet 041. The sewage discharge elastic member 0422 is connected to the sewage switch fixing plate 0421 so that the sewage discharge pressing member 0423 connected to the sewage discharge elastic member 0422 is connected to the sewage tank 04, and is pressed against the sewage outlet 041 under the elastic force of the sewage discharge elastic member 0422, thereby sealing the sewage outlet 041. The sewage tank 04 is sealed as a whole without the action of external force, preventing sewage from leaking, and ensuring the safety of the floor scrubber.

[0065] Preferably, Figures 10 to 13 As shown, the sewage discharge elastic member 0422 is a spring, which has good durability, high elastic potential energy, and low price, which effectively guarantees the service life of the sewage discharge mechanism 06 and reduces the production cost of the sewage discharge mechanism 06.

[0066] When the sewage discharge drive motor 061 is started, the sewage discharge drive gear 062 arranged on the output shaft of the sewage discharge drive motor 061 rotates accordingly, and the teeth of the driving rack 0651 meshing with the sewage discharge drive gear 062 drive the entire sewage switch top opening member 065 to move toward the sewage tank 04, so that the lifting part 0652 is aligned with the sewage discharge pressing member 0423 and lifts the sewage discharge pressing member 0423, and the sewage discharge pressing member 0423 squeezes the sewage discharge elastic member 0422 to compress the sewage discharge elastic member 0422, thereby allowing the sewage in the sewage tank 04 to flow out from the sewage outlet 041. After the sewage is discharged, the sewage drive motor 061 drives the sewage drive gear 062 to rotate in the opposite direction, thereby driving the drive rack 0651 meshing on the sewage drive gear 062 to drive the entire sewage switch top opening part 065 to move toward the sewage pipe 064, and the sewage switch top opening part 065 leaves the sewage pressure part 0423. The sewage pressure part 0423 is resisted on the sewage outlet 041 under the elastic force of the sewage elastic part 0422, thereby sealing the sewage outlet 041. The whole process is automatic and does not require manual participation, saving time and effort, and effectively improving the user experience of using the floor scrubber.

[0067] Preferably, in order to further improve the efficiency of the sewage switch top opening member 065 in lifting the sewage discharge pressing member 0423, as Fig.13 As shown, the end of the lifting part 0652 facing the sewage tank 04 is formed with a first inclined lifting surface 06521 extending obliquely from the upper part of the driving rack 0651 toward the lower part of the sewage tank 04, and the lower part of the sewage pressure member 0423 facing the sewage pipe 064 is formed with a second inclined lifting surface 04231 extending obliquely from the upper outside to the lower part of the sewage tank 04 and matching the first inclined lifting surface 06521. When the sewage switch lifting member 065 moves toward the sewage tank 04, The first inclined lifting surface 06521 on the sewage switch lifting member 065 first contacts with the second inclined lifting surface 04231. Under the inclined guiding action of the first inclined lifting surface 06521 and the second inclined lifting surface 04231, the sewage switch lifting member 065 can more easily and accurately lift the sewage discharge pressing member 0423 to allow the sewage to be discharged, thereby effectively improving the efficiency and accuracy of the sewage switch lifting member in lifting the sewage discharge pressing member 0423, and facilitating the coordination between the various components.

[0068] Regarding the specific way in which the sewage discharge pressing member 0423 moves when being lifted up, Fig.10 As shown, a movable pressing groove 043 is formed on the inner wall of the lower end of the sewage tank 04, which is opposite to the sewage outlet 041 and for the sewage discharge pressing member 0423 to move. The sewage discharge pressing member 0423 moves in the movable pressing groove 043 during the process of being pushed open by the sewage switch opening member 065, thereby meeting the space required for the moving trajectory when being pushed open, avoiding the sewage discharge pressing member 0423 from being blocked by foreign objects during movement, and improving the efficiency of the movement of the pressing member.

[0069] Preferably, Fig.10 As shown, the pressing movable groove 043 is half a round-headed column, and the lower end of the sewage pressing piece 0423 is a semi-arc shape matching the pressing movable groove 043. By setting the pressing movable groove 043 to be half a round-headed column, the rounded shape of the tail end can effectively limit the stroke of the sewage pressing piece 0423, preventing the sewage pressing piece 0423 from being excessively pressed by the jacking portion 0652. By setting the lower end of the sewage pressing piece 0423 to be a semi-arc shape matching the pressing movable groove 043, the sewage pressing piece 0423 can be limited to interact only in the pressing movable groove 043, preventing the sewage pressing piece 0423 from sliding left and right, causing the jacking portion 0652 to be stuck in other structures and unable to be pushed out. In addition, the half round-headed column is in an inclined state as a whole, so that the sewage in the sewage tank 04 can flow out more easily.

[0070] Preferably, in order to increase the speed at which sewage in the sewage tank 04 flows out, a water pump can be provided on the sewage tank 04 or on the sewage connection pipe 063 or on the sewage pipe 064, and the water pump draws sewage out of the sewage tank 04, thereby increasing the speed at which sewage in the sewage tank 04 flows out.

[0071] The specific method of the sewage switch top opening member 065 moving on the sewage connection pipe 063 is as follows: Fig.13 As shown, a driving movable groove 0631 for the movement of the sewage driving rack 0651 is formed on the sewage connection pipe 063, and the sewage driving rack 0651 moves in the driving movable groove 0631 under the drive of the sewage driving gear 062, thereby driving the entire sewage switch top opening member 065 to move on the sewage connection pipe 063, and the sewage switch top opening member 065 is limited by the front and rear travel of the driving movable groove 0631, thereby effectively preventing the lifting part 0652 from excessively lifting the sewage pressing member 0423 and causing it to be unable to reset. On both sides of the driving movable groove 0631, driving limit blocks 0632 extending upward and limiting the driving rack 0651 to the left and right are respectively formed, so that The left and right strokes of the driving rack 0651 are limited to prevent the driving rack 0651 from driving the lifting part 0652 to shift left and right, resulting in the lifting part 0652 being unable to lift the sewage pressure piece 0423 normally. A motor fixing plate 0633 for installing the sewage driving motor 061 is also extended upward on a group of driving limit blocks 0632 close to the sewage driving motor 061. The sewage driving motor 061 is installed on the motor fixing plate 0633 to achieve the stability of the sewage driving motor 061. The output shaft of the sewage driving motor 061 passes through the motor fixing plate 0633, and the sewage driving gear 062 is installed on the other end of its output shaft that passes through the motor fixing plate 0633, thereby engaging with the driving rack 0651.

[0072] Preferably, a limit block for limiting the lifting portion 0652 is further provided inside the sewage switch lifting member 065, thereby further preventing the lifting portion 0652 from shifting left and right in the sewage connecting pipe 063, resulting in the inability to accurately lift the sewage pressing member 0423.

[0073] Preferably, the upper end of the sewage tank 04 can be removed separately, and the entire sewage tank 04 can also be removed from the floor scrubber body 01, so that manual cleaning can be performed while automatically draining sewage. The two methods are provided for the user to choose, further improving the practicality of the floor scrubber.

[0074] Regarding the specific structural setting of the water adding mechanism 07, Figures 14 to 18As shown, the water adding mechanism 07 includes a limit box 071 arranged in the base 02 and matched with the scrubber body 01, a limit guide frame 072 arranged outside the limit box 071 and facing the clean water tank 03, a water adding drive motor 073 arranged on the limit guide frame 072, a water adding drive gear 074 arranged on the output shaft of the water adding drive motor 073, a water adding linkage gear 075 meshed with the water adding drive gear 074, a water adding pipe assembly 076 whose lower end is connected to the water adding linkage gear 075 and radially slides in the limit guide frame 072, and a water adding sealing assembly 077 rotatably arranged in the scrubber body 01 and facing the water adding pipe assembly 076.

[0075] In the absence of external force, the water adding seal component 077 seals the clean water tank 03. After the user places the floor scrubber body 01 into the base 02, the user can start the water adding drive motor 073 through the remote control or the button on the base 02. After the water adding drive motor 073 is started, it drives the water adding drive gear 074 disposed thereon to rotate, so that the water adding linkage gear 075 meshed with the water adding drive gear 074 rotates and pushes the water adding pipe component 076 disposed thereon to extend into the side of the clean water tank 03 to push the water adding seal component 077 open, so that the water adding pipe component 076 transmits the external clean water into the clean water tank 03 to complete the purpose of water filling. The whole process is simple and clear, with a high degree of automation, and does not require human participation, which is beneficial to people's daily use and effectively improves people's use experience. By setting a limit box 071 matching the floor washer body 01 in the base 02, the floor washer body 01 is placed in the limit box 071 when placed in the base 02, thereby achieving the purpose of fixing the position of the floor washer body 01 and preventing the floor washer body 01 from shifting during the automatic water filling process. By setting a limit guide frame 072 on the outside of the clean water tank 03, which extends radially outward as a whole, the water filling pipe assembly 076 can be limited in its radial structure and can only move along its direction, thereby effectively preventing the water filling pipe assembly 076 from shifting during operation, improving the accuracy and efficiency of the water filling pipe assembly 076 in pushing open the water filling seal assembly 077, and improving people's user experience.

[0076] Regarding the specific structural setting of the water adding linkage gear 075, as shown in FIG. Fig.16As shown, the water adding linkage gear 075 can be a gear set, wherein the first group is located at the lower end of the limiting guide frame 072 and meshes with the water adding drive gear 074, and the second group is located in the limiting guide frame 072 and is limited by the limiting guide frame 072. The axis is connected to the first group of gears and the upper end is connected to the water adding pipe assembly 076, thereby driving the water adding pipe assembly 076 and being limited by the limiting guide frame 072 to prevent the water adding pipe assembly 076 from shifting during operation, thereby effectively ensuring the normal operation of the automatic water adding mechanism 07.

[0077] Regarding the specific structural setting of the water supply pipeline assembly 076, as shown in FIG. Figures 14 to 18 As shown, the water adding pipe assembly 076 includes a water adding guide block 0761 whose lower end is arranged on the water adding linkage gear 075 and radially slides in the limiting guide frame 072, and a water injection pipe 0762 that passes through the water adding guide block 0761 and extends toward the clean water tank 03. The water adding guide block 0761 is connected to the water adding linkage gear 075, and is driven by the water adding drive motor 073 through the water adding linkage gear 075, so as to drive the water injection pipe 0762 arranged thereon to push the water adding seal assembly 077 open along the direction of the limit guide frame 072, and then the water injection pipe 0762 injects the external clean water into the clean water tank 03. After the water injection is completed, the external control mechanism controls the water adding drive motor 073 to drive the water adding guide block 0761 to drive the water injection pipe 0762 to move away from the clean water tank 03 in the limit guide frame 072, and the water adding seal assembly 077 blocks and seals the clean water tank 03 again, waiting for the next water addition. The whole process is simple and convenient, without human participation, and while realizing automatic water addition, it can also automatically stop water addition, further improving the user experience of the floor scrubber.

[0078] Preferably, Figures 14 to 17As shown, in order to further improve people's user experience, the water-adding pipeline assembly 076 also includes a return pipe 0763 that passes through the water-adding guide block 0761 and extends toward the clean water tank 03, and a liquid level sensor 0764 arranged at the tail end of the return pipe 0763. The water-adding guide block 0761 is connected to the water-adding linkage gear 075, so that it is driven by the water-adding drive motor 073 through the water-adding linkage gear 075, thereby driving the water injection pipe 0762 and the return pipe 0763 arranged thereon to push the water-adding sealing assembly 077 up along the direction of the limiting guide frame 072. After opening, the water injection pipe 0762 injects external clean water into the clean water tank 03. When the clean water reaches a certain level, the clean water in the clean water tank 03 flows back into the return pipe 0763 and is sensed by the liquid level sensor 0764 at its tail end. After receiving the feedback information from the liquid level sensor 0764, the external control mechanism controls the external water source to stop injecting, and controls the water adding drive motor 073 to drive the water adding guide block 0761 to drive the water injection pipe 0762 and the return pipe 0763 to move away from the clean water tank 03 in the limit guide frame 072. The water adding seal component 077 re-seals the clean water tank 03 and waits for the next water addition. The whole process is simple and convenient, without human participation, and while realizing automatic water addition, it can also automatically stop water addition, further improving the user experience of the floor scrubber. Regarding the specific structural setting of the liquid level sensor 0764, the structure and operation mode of the liquid level sensor 0764 are existing public technologies, and its model etc. can be selected according to actual conditions, so they will not be described in detail in this embodiment.

[0079] Preferably, Figures 14 to 17 As shown, the height of the water injection pipe 0762 is higher than the height of the return pipe 0763, so that the return pipe 0763 receives the water source returning from the clean water tank 03 before the water injection pipe 0762, thereby more accurately controlling the amount of water in the clean water tank 03, and preventing the water source from returning to the water injection pipe 0762 and colliding with the water source in the water injection pipe 0762, causing the water injection pipe 0762 to break. The water adding guide block 0761 can be set in a stepped shape according to the height of the water injection pipe 0762 and the return pipe 0763.

[0080] The specific method for the water adding guide block 0761 to move radially in the limiting guide frame 072 is as follows: Figures 14 to 17As shown, water addition limiting flanges 0721 protruding inwards are respectively formed on both side edges of the limiting and guiding frame 072. Water addition limiting grooves 07611 recessed inwards and matching with the water addition limiting flanges 0721 are respectively formed on both sides of the water addition guiding block 0761. The water addition limiting flanges 0721 protrude into the water addition limiting grooves 07611, so that the water addition guiding block 0761 slides along the water addition limiting flanges 0721 during the moving process, and thus is limited by the stroke of the water addition limiting flanges 0721, effectively preventing the situation that the water addition guiding block 0761 is displaced during the moving process, making the movement of the water addition guiding block 0761 more precise, and effectively improving the working efficiency of the water addition pipeline assembly 076.

[0081] Preferably, as Figures 14 to 16 shown, in order to further prevent the water addition guiding block 0761 from being displaced, the limiting and guiding frame 072 further includes an upper limiting and guiding block 0722 formed on the side edge of the limiting box 071 and limiting the upper end of the water addition guiding block 0761. The upper end of the water addition guiding block 0761 abuts against the inner side of the lower end of the upper limiting and guiding block 0722. The upper limiting and guiding block 0722 is integrally U-shaped, so as to limit the side of the water addition guiding block 0761, making the upper end of the water addition guiding block 0761 can only move along the upper limiting and guiding block 0722, effectively preventing the situation that the water addition guiding block 0761 is displaced during the moving process, making the movement of the water addition guiding block 0761 more precise, and effectively improving the working efficiency of the water addition pipeline assembly 076. For other structures of the upper limiting and guiding block 0722, they can be set according to the structures of the water injection pipe 0762 and the return pipe 0763, so they will not be elaborated in this embodiment.

[0082] For the specific manner in which the water addition linkage gear 075 drives the water addition guiding block 0761, as Fig.17 shown, a linkage activity groove 07612 extending horizontally is formed at the lower end of the water addition guiding block 0761. A water addition linkage column 0751 protruding upwards to extend into the linkage activity groove 07612 for sliding is formed on the water addition linkage gear 075. When the water addition driving gear 074 drives the water addition linkage gear 075 to rotate, the water addition linkage column 0751 on the water addition linkage gear 075 moves in the linkage activity groove 07612. Since the rotation trajectory of the water addition linkage gear 075 is circular, when the water addition linkage column 0751 slides in the linkage activity groove 07612, it drives the water addition guiding block 0761 radially, and cooperates with the limiting and guiding frame 072 to limit the water addition guiding block 0761, so that the water addition guiding block 0761 moves stably radially in the limiting and guiding frame 072, ensuring the normal operation of the automatic water addition mechanism 07.

[0083] Preferably, as Fig.14 As shown, a stop block is also provided at one end of the limiting guide frame 072 away from the clean water tank 03, thereby effectively preventing the water adding guide block 0761 from moving excessively in the limiting guide frame 072 and thus falling off.

[0084] The specific structural setting for water injection and reflux on the clean water tank 03 is as follows: Figure 3 As shown, a water injection port 031 for the water injection pipe 0762 to be placed in, and a return port 032 for the return pipe 0763 to be placed in are formed on the side of the clean water tank 03. When water injection is required, the water injection pipe 0762 passes through the water injection port 031 to push open the water adding seal assembly 077, and the return pipe 0763 passes through the return port 032 to push open the water adding seal assembly 077, so that the external clean water can enter the clean water tank 03 through the water injection pipe 0762, and the excess water in the clean water tank 03 can be returned and controlled through the return pipe 0763.

[0085] Regarding the specific structural setting of the water adding sealing component 077, as shown in FIG. Fig.18 As shown, the water-adding seal assembly 077 includes a water-adding seal fixing column 0771 arranged on the inner wall of the clean water tank 03, a water-adding seal pressure plate 0772 rotatably arranged on the water-adding seal fixing column 0771, and a torsion spring 0773 sleeved between the water-adding seal fixing column 0771 and the water-adding seal pressure plate 0772, and the water-adding seal pressure plate 0772 is formed with a water-adding pressure boss 07721 protruding toward the water injection port 031 and resisting and sealing the water injection port 031, and a water-adding pressure boss 07721 protruding toward the reflux port 032 and resisting and sealing the water injection port 031. The reflux port 032 resists the seal of a reflux pressing boss 07722. When no external force is applied, the water adding seal pressing plate 0772 is pressed against the inner wall of the clean water tank 03 under the elastic force of the torsion spring 0773, and the water injection pressing boss 07721 thereon presses against the water injection port 031, thereby sealing the water injection port 031, and the reflux pressing boss 07722 thereon presses against the reflux port 032, thereby sealing the reflux port 032. The two cooperate with each other to seal the clean water tank 03 as a whole, thereby ensuring that clean water will not leak out at will during the use of the floor scrubber. When water needs to be added, the water injection pipe 0762 passes through the water injection port 031 and presses against the water injection pressing boss 07721, and the return pipe 0763 passes through the return port 032 and presses against the return port 032. The two cooperate with each other to push open the water adding sealing pressure plate 0772, so that the external clean water can enter the clean water tank 03 through the water injection pipe 0762, and the excess water in the clean water tank 03 can be refluxed and controlled through the return pipe 0763.
