[0040] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0041] Below, reference is made to Figures 1 - 8 Describe the wiper strip mechanism according to the embodiments of the present utility model. A floor washer including the above wiper strip mechanism is also proposed. The floor washer can be a passive machine (such as a wet mopping machine, a dry / wet suction mopping machine), or an active machine (such as a sweeping and mopping robot).

[0042] Such as Figure 1As shown, the floor brush 100 includes a roller brush 24 and a scraper mechanism, which can be used as a front scraper and arranged in front of the roller brush 24, so as to scrape off the sewage when the floor scrubber is pulled back. The floor brush 100 can also include a rear scraper assembly 21, which is arranged on the rear side of the roller brush 24, so as to scrape off the sewage when the floor scrubber is pushed forward. Specifically, the roller brush 24 and the rear scraper assembly 21 form a diversion port, and a diversion channel is arranged in the floor brush 100, which connects the diversion port and the suction source so that the sewage enters the sewage tank from the diversion channel. When the floor scrubber moves forward and works, the roller brush 24 runs at a high speed to guide the sewage on the ground to the rear scraper assembly 21. After the rear scraper assembly 21 scrapes off the sewage, the sewage is pumped into the sewage tank through the suction source. Among them, a flexible member is arranged at the lower end of the rear scraper assembly 21, and the flexible member is interference fit with the cleaned surface, so that the sewage is scraped off more thoroughly.

[0043] according to Figures 3 - 8 As shown, the scraper mechanism includes: a scraper assembly 10, and the scraper assembly 10 includes: a first scraper 11 and a second scraper 12. Specifically, the scraper assembly 10 is arranged on the front side of the roller brush 24, the scraper assembly 10 and the rear scraper assembly 21 are respectively arranged on both sides of the roller brush 24, the first scraper 11 and the second scraper 12 are connected to each other, the first scraper 11 is arranged close to the roller brush 24, and the second scraper 12 is arranged on the side of the first scraper 11 away from the roller brush 24.

[0044] like Figure 6 As shown, the first scraper bar 11 and the second scraper bar 12 are arranged side by side, and a dirt suction cavity 13 is formed between the first scraper bar 11 and the second scraper bar 12 to absorb the sewage when the scrubber is pulled backward. A dirt suction cavity 13 is formed between the second scraper bar 12 and the first scraper bar 11, and the sewage can enter the scrubber from the dirt suction cavity 13 to remove the sewage remaining on the cleaned surface (such as the ground) when the scrubber is pulled backward. The dirt suction cavity 13 can be connected to the suction source. When the scrubber is pulled backward, the scraper bar assembly 10 abuts against the cleaned surface, that is, the scraper bar assembly 10 has an interference fit with the cleaned surface, one end of the dirt suction cavity 13 is in contact with the cleaned surface, and the other end is connected to the suction source. Under the suction of the suction source, the sewage enters the dirt suction cavity 13 to remove the water stains remaining on the cleaned surface.

[0045] The scraper mechanism may include: a driving assembly, the driving assembly is in transmission connection with the scraper assembly 10, and the driving assembly is used to drive the scraper assembly 10 to move so that the dirt suction cavity 13 is close to or away from the cleaned surface. That is to say, since there is a certain distance between the scraper assembly 10 and the roller brush 24, sewage will remain between the scraper assembly 10 and the roller brush 24. When pushed forward, the driving assembly drives the scraper assembly 10 to move until the dirt suction cavity 13 is away from the cleaned surface; when pulled backward, the driving assembly drives the scraper assembly 10 to move until the dirt suction cavity 13 is close to the cleaned surface, so that the sewage in the area between the scraper assembly 10 and the roller brush 24 enters from the dirt suction cavity 13, avoiding residual sewage stains.

[0046] Thus, when the floor washer is pulled backward, the driving component drives the squeegee component 10 to move to a position where the sewage suction cavity 13 is close to the surface to be cleaned, and the sewage remaining in the area between the squeegee component 10 and the roller brush 24 can enter the sewage suction cavity 13, avoiding the residue of sewage water stains.

[0047] The squeegee component 10 has the following two working positions driven by the driving component:

[0048] (1) Water scraping working position: When the floor washer moves backward, the squeegee component 10 is driven by the driving component, and the lower end of the squeegee component 10 abuts against the surface to be cleaned to scrape off the water stains on the surface to be cleaned. In this embodiment, the lower end of the squeegee component 10 can form an interference fit with the surface to be cleaned.

[0049] (2) Suspended working position: When the floor washer moves forward, the squeegee component 10 rotates backward under the drive of the driving component and reaches a suspended state, and the bottom end of the squeegee component 10 is far away from the surface to be cleaned.

[0050] In the suspended working position, in the up and down direction, the lower end of the squeegee component 10 does not contact the surface to be cleaned, and there is a distance between the lower end of the squeegee component 10 and the surface to be cleaned, and the distance can be between 3 mm (millimeters) and 3 cm (centimeters), such as 4 mm, 5 mm or 6 mm.

[0051] As Figure 4 and Figure 7 shown, a first reinforcing rib 111 is provided on the first squeegee 11, and the first reinforcing rib 111 is located between the first squeegee 11 and the second squeegee 12 to form a sewage suction cavity 13 between the first squeegee 11 and the second squeegee 12. Specifically, a first reinforcing rib 111 is provided on the side of the first squeegee 11 facing the second squeegee 12, and the first reinforcing rib 111 can abut against the second squeegee 12, or the first reinforcing rib 111 can also be connected to the second squeegee 12 to form a sewage suction cavity 13 between the first squeegee 11 and the second squeegee 12.

[0052] In some other embodiments, a first reinforcing rib 111 is provided on the second squeegee 12, and the first reinforcing rib 111 is arranged between the first squeegee 11 and the second squeegee 12 to form a sewage suction cavity 13. The first reinforcing rib 111 can abut against the first squeegee 11, or the first reinforcing rib 111 can also be connected to the first squeegee 11 to form a sewage suction cavity 13 between the first squeegee 11 and the second squeegee 12.

[0053] The first reinforcing rib 111 is clamped between the first squeegee 11 and the second squeegee 12, preventing the first squeegee 11 and the second squeegee 12 from being attached due to excessive suction force, resulting in the closure of the sewage suction cavity 13 and affecting the effect of sewage removal.

[0054] Among them, there may be multiple first reinforcing ribs 111, and the multiple first reinforcing ribs 111 are arranged at intervals on the first scraping strip 11 and / or the second scraping strip 12.

[0055] As Figure 8 shown, on the side of the first scraping strip 11 facing the roller brush 24, a third reinforcing rib 112 is provided. The third reinforcing rib 112 protrudes towards the roller brush 24, and the third reinforcing rib 112 is in interference fit with the surface to be cleaned, which can increase the friction between the first scraping strip 11 and the surface to be cleaned and ensure the sewage scraping ability of the scraping strip assembly 10.

[0056] The first scraping strip 11 and the second scraping strip 12 respectively have an upper end surface and a lower end surface; the first scraping strip 11 and the second scraping strip 12 are connected through their respective upper end surfaces; the lower end surfaces of the first scraping strip 11 and the second scraping strip 12 are free ends, and the lower end surface of the second scraping strip 12 is lower than the lower end surface of the first scraping strip 11. Specifically, when the floor washer is pulled backward, the scraping strip assembly 10 flips forward. The lower end surface of the second scraping strip 12 is lower than the lower end surface of the first scraping strip 11, which can ensure an interference fit between the second scraping strip 12 and the surface to be cleaned after flipping, realize the function of scraping water, and ensure that there is no water stain residue on the surface to be cleaned after the floor washer finishes cleaning.

[0057] The scraping strip mechanism further includes: a support member 23. The support member 23 is respectively connected to the upper end surfaces of the first scraping strip 11 and the second scraping strip 12. The support member 23 provides an installation point for the first scraping strip 11 and the second scraping strip 12. A part of the support member 23 is located between the first scraping strip 11 and the second scraping strip 12, providing a supporting force for the first scraping strip 11 and the second scraping strip 12, and preventing the gap between the first scraping strip 11 and the second scraping strip 12 from becoming smaller, which may cause the sewage suction cavity 13 to close and affect the effect of sewage removal.

[0058] In some embodiments, the scraping strip mechanism further includes: an air duct assembly. The air duct assembly is connected to the sewage suction cavity 13 and is used to transmit air flow to the sewage suction cavity 13. Specifically, the air duct assembly transmits the air flow to the sewage suction cavity 13. If the air flow is a suction force, the sewage can enter the sewage suction cavity 13 to remove the sewage remaining on the surface to be cleaned when the floor washer is pulled backward; if the air flow is a blowing force, the air flow blows out from the sewage suction cavity 13 to dry the sewage remaining on the surface to be cleaned when the floor washer is pulled backward, so as to achieve the removal of the sewage remaining on the surface to be cleaned when the floor washer is pulled backward.

[0059] Among them, the first scraping strip 11 can be a flexible member, so that when the floor washer is pulled backward, the first scraping strip 11 is in interference fit with the surface to be cleaned, ensuring the effect of removing sewage stains.

[0060] In some embodiments, the first scraping strip 11 and the second scraping strip 12 are of an integrally formed structure. The integrally formed first scraping strip 11 and the second scraping strip 12 can ensure the connection strength between the first scraping strip 11 and the second scraping strip 12, reduce the assembly process, and improve the assembly efficiency.

[0061] Combined Figures 2 - 8 As shown, the driving assembly includes: at least one flipping member 22. One end of the flipping member 22 is connected to the upper end of the squeegee assembly 10. The lower end surface of the flipping member 22 is lower than the lower end surface of the squeegee assembly 10. The flipping member 22 can drive the squeegee assembly 10 to move, so that the sewage suction cavity 13 approaches or moves away from the surface to be cleaned. Specifically, when the floor washer is pushed forward, the flipping member 22 flips backward, driving the squeegee assembly 10 to flip backward. Since the lower end surface of the flipping member 22 is lower than the lower end surface of the squeegee assembly 10, there is a gap between the squeegee assembly 10 and the surface to be cleaned. And when the floor washer is pulled backward, it drives the squeegee assembly 10 to flip forward.

[0062] When the floor brush 100 moves backward, the squeegee assembly 10 rotates forward under the drive of the flipping member 22 and reaches a state that is basically downward. The lower end of the squeegee assembly 10 abuts against the surface to be cleaned, and the lower end of the sewage suction cavity 13 fits against the surface to be cleaned to absorb sewage and remove the water stains on the surface to be cleaned; in this embodiment, the lower end of the squeegee assembly 10 forms an interference fit with the surface to be cleaned.

[0063] When the floor brush 100 moves forward, the squeegee assembly 10 rotates backward under the drive of the flipping member 22 and reaches a suspended state, and the lower end of the squeegee assembly 10 is far away from the surface to be cleaned.

[0064] In addition, the flipping member 22 is arranged obliquely downward, so that it has a degree of freedom of movement for frictional contact with the surface to be cleaned back and forth. When the floor brush 100 moves backward, the flipping member 22 rotates forward under the drive of the frictional force; when the floor brush 100 moves forward, the flipping member 22 rotates backward under the drive of the frictional force.

[0065] In this embodiment, there can be multiple flipping members 22, such as two or three. Taking two as an example, the two flipping members 22 are respectively arranged at the two side edges of the squeegee assembly 10. The flipping member 22 is fixedly connected to the squeegee assembly 10.

[0066] In some embodiments, a first installation groove 231 is provided on the support member 23, and the flipping member 22 is connected to the first installation groove 231. The bonding method can be adopted to ensure the connection strength between the flipping member 22 and the support member 23, and the operation is simple.

[0067] Such as Figure 7As shown, a second mounting groove 232 is provided on the support member 23. The second mounting groove 232 opens downward. The upper end of the first scraping strip 11 is fitted in the second mounting groove 232. The first scraping strip 11 is fixedly connected to the second mounting groove 232. One side of the support member 23 facing the roller brush 24 is connected to the first scraping strip 11. A plurality of second reinforcing ribs 233 are provided on the support member 23. The plurality of second reinforcing ribs 233 are provided between the support member 23 and the second scraping strip 12. Then, there is a gap between the support member 23 and the second scraping strip 12. A dirt suction cavity 13 is formed between the second scraping strip 12 and the first scraping strip 11. The dirt suction cavity 13 communicates with the connection cavity 33 through the gap.

[0068] In some other embodiments, the driving assembly includes: a driving member, which is in transmission connection with the upper end of the scraping strip assembly 10, and the driving member drives the scraping strip assembly 10 to rise or fall. For example, the driving member can be a motor.

[0069] When the floor washer is pushed forward, the driving member drives the scraping strip assembly 10 to move upward, so that there is enough clearance between the scraping strip assembly 10 and the surface to be cleaned; when the floor washer is pulled backward, the driving member drives the scraping strip assembly 10 to move downward, so that the scraping strip assembly 10 fits the surface to be cleaned, and can scrape off the residual water and residual debris on the surface to be cleaned, thereby improving the cleaning degree of the surface to be cleaned. Therefore, whether the floor washer is in the forward-pushing state or the backward-pulling state, it is performing the corresponding cleaning function, improving the floor washing efficiency.

[0070] Preferably, the driving assembly further includes: a transmission member, the two ends of the transmission member are respectively connected to the driving member and the scraping strip assembly 10, and the transmission member is used to drive the scraping strip assembly 10 to move upward or downward when driven by the driving member. The transmission member can drive the scraping strip assembly 10 to rise or fall under the drive of the driving member, that is, the driving force of the driving member is converted into a vertical force on the scraping strip assembly 10 through the transmission member, thereby realizing the rise or fall of the scraping strip assembly 10. Among them, the transmission member can be a rack, a connecting rod and other structures.

[0071] Embodiment 2:

[0072] The scraping strip mechanism includes: a scraping strip assembly 10 and a driving assembly. An air duct is provided inside the scraping strip assembly 10; the driving assembly is in transmission connection with the scraping strip assembly 10, and the driving assembly drives the scraping strip assembly 10 to move, and is used to drive the scraping strip assembly 10 to switch between a first position and a second position; wherein, the acting force of the air duct on the surface to be cleaned in the first position is greater than the acting force of the air duct on the surface to be cleaned in the second position. Among them, the acting force can be the negative pressure formed by suction or the positive pressure brought by blowing.

[0073] When the floor washer is pulled backward, the squeegee assembly 10 can be in the first position. The negative or positive pressure of the air duct on the surface to be cleaned can suck sewage into the air duct or blow it dry to achieve the purpose of removing sewage.

[0074] When the squeegee assembly 10 is in the second position, the negative or positive pressure of the air duct on the surface to be cleaned can be 0 or close to 0; perhaps relative to the squeegee assembly 10 being in the first position, the negative or positive pressure of the air duct on the surface to be cleaned is reduced. When the floor washer is pushed forward, the squeegee assembly 10 can be in the second position to assist the rear squeegee assembly 21 in removing sewage.

[0075] Sewage can enter the floor washer from the air duct to remove the sewage remaining on the bottom surface when the floor washer is pulled backward. The air duct can be connected to a suction source. When the floor washer is pulled backward, the air duct approaches the surface to be cleaned, and the squeegee assembly 10 abuts against the surface to be cleaned, that is, the squeegee assembly 10 has an interference fit with the surface to be cleaned. One end of the air duct is attached to the surface to be cleaned, and the other end is connected to the suction source. Under the suction of the suction source, sewage enters the air duct to remove the water stains remaining on the surface to be cleaned.

[0076] Specifically, the squeegee assembly 10 has the following two working positions driven by the driving assembly:

[0077] (1) Water scraping working position: When the floor washer moves backward, the squeegee assembly 10 is driven by the driving assembly, and the lower end of the squeegee assembly 10 abuts against the surface to be cleaned, and the air duct is attached to the surface to be cleaned to scrape off the water stains on the surface to be cleaned. In this embodiment, the lower end of the squeegee assembly 10 can form an interference fit with the surface to be cleaned. At this time, the squeegee assembly 10 can be in the first position.

[0078] (2) Suspended working position: When the floor washer moves forward, the squeegee assembly 10 rotates backward under the drive of the driving assembly to reach a suspended state, and the lower end of the squeegee assembly 10 is far from the surface to be cleaned. At this time, the squeegee assembly 10 can be in the second position.

[0079] In addition, a first reinforcing rib 111 is arranged in the air duct. The first reinforcing rib 111 divides the air duct into at least two sub-air ducts. The first reinforcing rib 111 is arranged in the squeegee assembly 10 to support the air duct and prevent the air duct from closing, affecting the effect of sewage removal.

[0080] Combined with Figures 2 - 8As shown in the figure, the driving assembly includes: at least one flipping member 22, one end of the flipping member 22 is connected to the upper end of the scraping strip assembly 10, the lower end surface of the flipping member 22 is lower than the lower end surface of the scraping strip assembly 10, and the flipping member 22 can drive the scraping strip assembly 10 to move, so that the air duct is close to or away from the surface to be cleaned. Specifically, when the floor washer is pushed forward, the flipping member 22 flips backward, driving the scraping strip assembly 10 to flip backward. Since the lower end surface of the flipping member 22 is lower than the lower end surface of the scraping strip assembly 10, there is a gap between the scraping strip assembly 10 and the surface to be cleaned. And when the floor washer is pulled backward, it drives the scraping strip assembly 10 to flip forward.

[0081] When the floor brush 100 moves backward, the scraping strip assembly 10 rotates forward under the drive of the flipping member 22 and reaches a state where it is basically downward. The lower end of the scraping strip assembly 10 abuts against the surface to be cleaned, and the lower end of the air duct fits with the surface to be cleaned to absorb sewage and remove the water stains on the surface to be cleaned; in this embodiment, the lower end of the scraping strip assembly 10 forms an interference fit with the surface to be cleaned.

[0082] When the floor brush 100 moves forward, the scraping strip assembly 10 rotates backward under the drive of the flipping member 22 and reaches a suspended state, and the lower end of the scraping strip assembly 10 is far away from the surface to be cleaned.

[0083] In addition, the flipping member 22 is arranged obliquely downward, so that it has the freedom of movement to rub against the surface to be cleaned back and forth. When the floor brush 100 moves backward, the flipping member 22 rotates forward under the drive of the frictional force; when the floor brush 100 moves forward, the flipping member 22 rotates backward under the drive of the frictional force.

[0084] In this embodiment, there can be two flipping members 22, and the two flipping members 22 are respectively arranged at the two side edges of the scraping strip assembly 10. The flipping member 22 is fixedly connected to the scraping strip assembly 10.

[0085] In some other embodiments, the driving assembly includes: a driving member, the driving member is in transmission connection with the upper end of the scraping strip assembly 10, and the driving member drives the scraping strip assembly 10 to rise or fall. Among them, the driving member can be a motor.

[0086] When the floor washer is pushed forward, the driving member drives the scraping strip assembly 10 to move upward, so that there is enough gap between the scraping strip assembly 10 and the surface to be cleaned; when the floor washer is pulled backward, the driving member drives the scraping strip assembly 10 to move downward, so that the scraping strip assembly 10 fits with the surface to be cleaned, and can scrape off the residual water and residual debris on the surface to be cleaned, thereby improving the cleaning degree of the surface to be cleaned.

The transmission member can drive the squeegee assembly 10 to rise or fall under the drive of the driving member, that is, the driving force of the driving member is converted into a vertical force on the squeegee assembly 10 through the transmission member, so as to realize the rise or fall of the squeegee assembly 10. Among them, the transmission member can be a rack, a connecting rod and other structures.

[0088] Embodiment Three:

[0089] The floor washer according to the third aspect embodiment of the present invention includes: a floor brush 100, a main air duct member 25, a suction source (such as a blower), and a sewage tank. Among them, the floor brush 100 includes a squeegee mechanism and a diversion channel, and the suction source is communicated with the diversion channel of the floor brush 100 through the main air duct member 25, so that sewage enters the sewage tank from the diversion channel. In addition, the suction source is also communicated with the squeegee assembly 10 through the main air duct member 25. When the floor washer is pulled backward, under the suction force of the suction source, the residual sewage on the ground can enter the sewage tank from the squeegee assembly 10, solving the problem of sewage residue on the surface to be cleaned.

[0090] Specifically, as Figures 3 - 6 shown, the main air duct member 25 is provided with a connection port 251. Specifically, a main air duct is formed in the main air duct member 25, the main air duct is communicated with the suction source, a connection port 251 is arranged at the end of the main air duct, and the main air duct member 25 is communicated with the squeegee assembly 10 through the connection port 251.

[0091] In one embodiment, the squeegee mechanism further includes an air duct assembly. The air duct assembly includes an auxiliary air duct member 26. One end of the auxiliary air duct member 26 is communicated with the squeegee assembly 10 and the other end is communicated with the connection port 251, that is, the auxiliary air duct member 26 communicates the squeegee assembly 10 and the main air duct member 25. Under the action of the suction source, the sewage at the squeegee assembly 10 can enter the auxiliary air duct member 26 from the squeegee assembly 10, and finally enter the main air duct from the connection port 251 and finally enter the sewage tank, thereby solving the problem of sewage residue on the surface to be cleaned.

[0092] When the floor washer is pulled backward, under the suction force of the suction source, the residual sewage on the ground can enter the auxiliary air duct member 26 from the squeegee assembly 10, flow through the connection port 251 and enter the main air duct member 25, and finally flow into the sewage tank, solving the problem of sewage residue on the surface to be cleaned. When the floor washer is pushed forward, under the suction force of the suction source, the sewage on the ground enters the main air duct member 25 from the rear squeegee assembly 21 and finally flows into the sewage tank to remove the sewage on the surface to be cleaned.

[0093] In one embodiment, the auxiliary air duct member 26 includes a cover plate assembly 30. One end of the cover plate assembly 30 is connected to the squeegee assembly 10. The cover plate assembly 30 includes: a first cover plate 31 and a second cover plate 32. The first cover plate 31 and the second cover plate 32 are connected and a connection cavity 33 is formed therebetween. Specifically, a connection cavity 33 is provided inside the cover plate assembly 30. One end of the connection cavity 33 is in communication with the squeegee assembly 10 and the other end is in communication with the suction source. The connection cavity 33 connects the suction source and the squeegee assembly 10. When the floor washer is pulled backward, under the suction of the suction source, the sewage is pumped into the squeegee assembly 10 and then into the sewage tank, thereby removing the water stains remaining on the surface to be cleaned. At the same time, the cover plate assembly 30 can also serve as the cover plate of the roller brush 24 and is in interference contact with the roller brush 24 to cooperate with the roller brush 24 to perform the mopping work. By arranging the connection cavity 33 on the cover plate of the roller brush 24, the connection structure between the squeegee mechanism and the suction source can be simplified.

[0094] In actual use, the floor washer needs to move forward and backward alternately for a comprehensive cleaning. When the floor washer moves forward, the rear squeegee assembly 21 functions to scrape off water stains. At this time, the front squeegee assembly 10 is in a suspended working position; when the floor washer moves backward, the front squeegee assembly 10 functions to scrape off water stains and absorb sewage, thus completely solving the problem of sewage residue on the surface to be cleaned and improving the cleaning effect.
