[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] like Figures 1 to 6 As shown, the floor brush module in this embodiment includes a housing 1, a scraper bar assembly, and a water spray port 12.

[0034] The housing 1 is provided with a dust suction channel inside, which can be used to suck the dirt cleaned on the ground into the dust suction channel, thereby completing the collection of the dirt on the ground. The bottom surface of the housing 1 is provided with a dust suction port 11 facing the ground and connected to the dust suction channel. The dust suction port 11 is provided at the rear of the bottom surface of the housing 1, and the dust suction port 11 extends a distance along the width direction of the housing 1, thereby ensuring a sufficient dust suction inlet area. The bottom surface of the housing 1 is usually provided with a mechanism such as a walking wheel, so that when in use, the bottom surface of the housing 1 is at a certain distance from the ground.

[0035] The scraper bar assembly includes at least one group of scraper bars 2 symmetrically arranged on both sides of the dust suction port 11 along the width direction, and the scraper bars 2 can be arranged on the bottom surface of the housing 1 to rotate and swing forward and backward. The scraper bars 2 are located in the gap between the bottom surfaces of the housing 1 and are in interference contact with the ground to achieve scraping and cleaning of the ground. The number of groups of scraper bars 2 is specifically set according to the area of ​​the housing 1. For example, the scraper bar assembly can include at least two groups of scraper bars 2 symmetrically arranged on both sides of the dust suction port 11 along the width direction, thereby facilitating the front and rear swing drive of the scraper bars 2, and also allowing the scraper bars 2 to present a variety of forms. Specifically, in this embodiment, the scraper strips 2 on the same side of each group of scraper strip assemblies are linearly spliced ​​based on swinging, that is, they are connected in a straight line, so that the scraper strip assembly forms a V-shaped gathering piece relative to the dust suction port 11, and the middle part of the scraper strips 2 on both sides of the dust suction port 11 forms a narrow gap corresponding to the position of the dust suction port 11. When the fan module in the housing 1 described below is working, the gap forms the position with the highest wind speed, which can quickly take away the dirt on the ground on the front side of the housing 1 and enter the dust suction channel through the dust suction port 11. In addition, the scraper strips 2 can also be separated based on swinging, and then these scraper strips 2 can form multiple channels leading to the dust suction port 11, which is conducive to quickly collecting residual water on the scraper strips 2 and reducing shutdown residues.

[0036] The water spray port 12 is opened on the bottom surface of the casing 1 along the width direction and is located on the front side of the scraper strip assembly. When the floor is cleaned, the water spray port 12 sprays water on the floor to wet the stains on the floor, especially the dry stains stuck on the floor. Combined with the scraping force of the scraper strip 2 when moving with the casing 1, the floor stains can be effectively cleaned to ensure the cleaning effect.

[0037] A rear scraper 3 is provided on the bottom surface of the casing 1 along the width direction. The rear scraper 3 can be made of a deformable material, so that the rear scraper 3 can make interference contact with the ground, thereby scraping and cleaning the ground. The rear scraper 3 is arranged on the rear side of the scraper bar assembly. Preferably, the rear scraper 3 is arranged at the rear edge of the dust suction port 11, so that the dirt on the ground can be gathered on the front side of the rear scraper 3, a dust collecting area is formed on the front side of the rear scraper 3, and based on the action of the scraper bar 2, the sewage is guided into the dust suction port 11.

[0038] The front scraper 4 is provided on the floor of the housing 1 and swings up and down along the width direction. The front scraper 4 is arranged at the front side of the scraper assembly. When in use, when the cleaning work is performed by pushing forward, the front scraper 4 flips upward, and the dirt on the floor can be sucked from the front side of the housing 1 to the dust suction port 11, and then the cleaning is achieved. When the cleaning machine is pulled backward, the front scraper 4 flips down, and the gap between the front side of the floor of the housing 1 and the floor is blocked by the front scraper 4, and then the particles and water are intercepted in the cavity formed between the front scraper 4 and the rear scraper 3. Since the front scraper 4 is in interference contact with the floor after flipping down, the "return water stains" of the cleaning machine are ensured to be uniform. When working, the front scraper 4 is in a wet state, and the stains are peeled off and transmitted backwards through contact with the floor, and are transmitted to the rear scraper 2 through the front scraper 4. Through the cooperation of the rear scraper 2 and the negative pressure suction of the cleaning machine, the garbage and water stains are efficiently brought into the dust suction channel after being infiltrated with the floor.

[0039] In order to swing autonomously in coordination with the mopping action, the housing 1 is provided with a first driving assembly that drives the front scraper 4 to swing up and down. The first driving assembly in this embodiment includes a motor 5, a swing arm 6 rotatably connected to the driving end of the motor 5, and a first elastic member 7 arranged at both ends of the front scraper 4. The front scraper 4 is provided with an action portion 41 corresponding to the swing arm 6, which can swing down based on the push of the swing arm 6. In this embodiment, the action portion 41 is arranged in the middle of the upper edge of the front scraper 4. The first elastic member 7 has a tendency to press the front scraper 4 to flip up. In this embodiment, the first elastic member 7 is a torsion spring.

[0040] When the cleaning machine is moving forward or stopped, under the action of the first elastic member 7, the first elastic member 7 presses the front scraper 4 to flip upward, so that the front gap of the housing 1 is in an open state. When the cleaning machine is moving backward, the motor 5 drives the swing arm 6 to swing downward, and the swing arm 6 triggers the action part 41 on the front scraper 4, pushing the action part 41 to rotate and swing upward, thereby causing the front scraper 4 to flip downward and close the gap on the front side of the housing 1 for dirt to enter. When the motor 5 drives the swing arm 6 to reset, the front scraper 4 returns to the upward swing state under the action of the first elastic member 7.

[0041] In addition, in order to cooperate with the mopping action to realize the autonomous swing of the scraper bar 2, a second driving component for driving the scraper bar 2 to rotate and swing forward and backward is provided on the housing 1. The second driving component includes a motor 5, a driving plate 8, and a swing shaft 9 corresponding to each scraper bar 2. The driving plate 8 is transmission-set at the driving end of the motor 5 and swings forward and backward based on the drive of the motor 5. The swing shaft 9 is rotationally positioned on the housing 1 and its two ends are respectively connected to the driving plate 8 and the scraper bar 2. The second driving component also includes a second elastic member 100, and a swing arm 6 rotationally connected to the driving end of the motor 5. The driving plate 8 moves backward based on the rotation of the swing arm 6. The second elastic member 100 is set at the rear side of the driving plate 8 and has a tendency to press the driving plate 8 forward. The second elastic member 100 in this embodiment is a spring.

[0042] As needed, the motor 5 and the swing arm 6 in the second drive assembly can be independently arranged, or they can be the same components as the motor 5 and the swing arm 6 in the first drive assembly. In the present embodiment, in order to simplify the structure and reduce the cost, the motor 5 and the swing arm 6 in the second drive assembly and the motor 5 and the swing arm 6 in the first drive assembly use the same components.

[0043] In order to ensure the stability of the swing of the scraper bar 2, a guide plate 200 is provided below the driving plate 8. A strip hole 81 matching the swing range of the scraper bar 2 is provided on the driving plate 8 along the width direction, and an arc hole 201 matching the swing range of the scraper bar 2 is provided on the guide plate 200 along the front-to-back direction. The ends of the swing shaft 9 pass through the strip hole 81 of the driving plate 8 and the arc hole 201 of the guide plate 200, respectively.

[0044] When the motor 5 does not drive the swing arm 6 to trigger the driving plate 8 to move, under the elastic pressure of the second elastic member 100, the driving plate 8 is at the frontmost position, and the driving plate 8 pulls the swing shaft 9 forward, so that the scraping strips 2 on the same side of the dust suction port 11 in each group of scraping strip assemblies form a long linear scraping strip 2, and then form a first state that is V-shaped, and the angle between the linear scraping strips 2 formed on both sides of the dust suction port 11 is relatively large, so as to meet the needs of the dirt on the ground to gather toward the dust suction port 11 as much as possible and effectively complete the cleaning work. This state is suitable for the cleaning machine to effectively have the dirt entering the bottom surface of the housing 1 when the cleaning machine is working, and then be sucked into the dust suction port 11. After the motor 5 drives the swing arm 6 to rotate upward and backward to trigger the driving plate 8, the driving plate 8 moves backward, and then drives the swing shaft 9 as a whole to form a swing path that rotates backward. At the same time, based on the bar hole 81 on the driving plate 8 and the arc hole 201 on the guide plate 200, the arc swing path of the swing shaft 9 can be met. Driven by the swing shaft 9, the scraper strip 2 is driven to swing, so that each scraper strip assembly is spread out to form a plurality of channels leading to the dust suction port 11. This state is defined as the second state of the scraper strip assembly. In this state, the angle of the scraper strip 2 relative to the front-to-back direction is smaller than the angle of the scraper strip 2 relative to the front-to-back direction in the first state. The second state of the scraper strip assembly is more suitable for use when the cleaning machine is stopped. In this way, under the action of large-flow suction, the water on the scraper strip 2 can be more smoothly sucked into the dust suction port 11, thereby reducing the residual water at the root of the rear scraper strip 2 and the controllable scraper strip 2, and reducing the shutdown residue.

[0045] When the cleaning machine stops working, the motor 5 drives the swing arm 6 to return to the original position. Correspondingly, under the elastic pressure of the second elastic member 100, the driving plate 8 returns to the frontmost position, and the scraper assembly also returns to the first state.

[0046] Of course, as needed, the motor 5 can also drive the swing arm 6 to drive the scraper bar 2 to swing back and forth in a cycle during the cleaning process, thereby improving the cleaning effect on the ground.

[0047] The utility model also relates to a cleaning machine, comprising a fan module, a water supply module 300, and a floor brush module as mentioned above, wherein the fan module is arranged in the casing 1 corresponding to the dust suction channel, the water supply module is arranged in the casing 1 and is fluidly connected to the water spray port 12, the water supply module 300 supplies water to the water spray port 12, and then sprays water onto the ground during cleaning, so that the cleaning machine can complete the tasks of sweeping and mopping the floor at the same time, thereby improving the cleaning effect.

[0048] The floor brush module in the utility model removes the rolling and rotating floor brush structure in the prior art. By setting a scraper bar 2 structure that can swing back and forth, combined with the suction force of the dust suction channel and the water sprayed from the water spray port 12, the dirt on the ground can be scraped and guided by the scraper bar 2, and then directly sucked into the dust suction channel through the dust suction port 11 to achieve cleaning of the ground. When the floor brush module of this structure is used in a cleaning machine, it can avoid problems such as hair entanglement and large particles flying. At the same time, based on the water spraying of the water spray port 12 and the scraping force of the scraper bar 2, the water infiltration time and peeling force of the dirt on the ground can be guaranteed, ensuring the cleaning power of dry stains on the ground.
