Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, and particularly relates to a floor brush and a cleaning equipment. BACKGROUND

[0002] With the improvement of living standards, auxiliary cleaning equipment for household cleaning has emerged as the times require. These cleaning devices can reduce the labor of users in household cleaning, and thus are widely favored by the current society.

[0003] When a user uses the cleaning equipment, the user often makes a reciprocating push-pull action, so that the cleaning equipment can repeatedly clean the same area and intensify cleaning. The current cleaning equipment uses liquid to brush the floor, and a scraping strip that abuts against the surface to be cleaned is arranged at the rear of the rolling brush, so that when the user pushes the cleaning equipment forward, the liquid and dirt on the surface to be cleaned are guided into the suction port, and the residual water on the surface to be cleaned is reduced. However, since no scraping strip is arranged in front of the rolling brush, when the user pulls the cleaning equipment backward, the residual water on the ground cannot be guided into the suction port, so that too much water stains remain on the ground, and the user experience is poor. SUMMARY

[0004] In view of the deficiencies of the prior art, one of the purposes of the present application is to provide a floor brush, which is provided with a front scraping strip and a rear scraping strip on both sides of a rolling brush. The front scraping strip and the rear scraping strip can abut against the surface to be cleaned, so that when the cleaning equipment is pushed forward or pulled backward, the scraping strip abuts against the surface to be cleaned to guide the liquid and dirt on the surface to be cleaned into the suction port, and the residual water on the surface to be cleaned is reduced.

[0005] To achieve the above purpose, the technical means adopted by the present application is as follows: a floor brush, comprising: a rolling brush, which can rotate in a preset direction; a front scraping strip, which can abut against the surface to be cleaned; a rear scraping strip, which can abut against the surface to be cleaned; and the front scraping strip and the rear scraping strip are respectively located on both sides of the rolling brush in the width direction of the floor brush.

[0006] The front scraping strip and the rear scraping strip are connected through a connecting assembly. After the front scraping strip and the rear scraping strip are connected, the movement of the front scraping strip and the rear scraping strip can be realized through one transmission device.

[0007] The floor brush further comprises a rolling wheel assembly and a transmission device, and the transmission device connects the rolling wheel assembly and the connecting assembly, so that when the rolling wheel assembly rotates, the connecting assembly is driven to move through the transmission device.

[0008] The transmission device comprises a gear, a rack, a rotating rod, a front limiting block and a rear limiting block opposite to the front limiting block in the width direction of the brush. The roller assembly comprises two rollers and a connecting rod connecting the two rollers. The gear is connected to the connecting rod. When the rollers rotate, the gear rotates in the same direction. The rack is engaged with the gear. The rotating rod is movably connected to the end of the rack away from the gear. The rotating rod can reciprocate between the front limiting block and the rear limiting block. When the rollers rotate forward, the gear rotates forward. At this time, the rack engaged with the gear also moves forward, so that one end of the rotating rod moves forward, and the other end is offset to the rear limiting block and applies a force to the rear limiting block, so that the connecting assembly moves backward until the rear scraper is in abutment with the surface to be cleaned, so that when the rollers rotate forward, the front scraper is lifted, and the rear scraper is in abutment with the surface to be cleaned. When the rollers rotate backward, the gear rotates backward. At this time, the rack engaged with the gear also moves backward, so that one end of the rotating rod moves backward, and the other end is offset to the front limiting block and applies a force to the front limiting block, so that the connecting assembly moves forward until the front scraper is in abutment with the surface to be cleaned, so that when the rollers rotate backward, the rear scraper is lifted, and the front scraper is in abutment with the surface to be cleaned.

[0009] The first driving device can drive the front scraper to move in the vertical direction in the first guide rail. The second driving device can drive the rear scraper to move in the vertical direction in the second guide rail. Two driving devices are used to control the front scraper and the rear scraper respectively. There is no connection between the front scraper and the rear scraper. Through electronic control, the resistance to the user is smaller than that in the mechanical control mode of the transmission device.

[0010] The inertial sensor is in communication with the main control board. The inertial sensor can identify the movement direction of the brush, and then send a signal to the main control board. The main control board can control the first driving device and the second driving device to operate or not according to the signal sent by the inertial sensor.

[0011] The cover assembly is detachably connected to the brush and can cover part of the roller brush. The first guide rail and the front scraper are arranged on the cover assembly. When the cover assembly is detached, the front scraper can be simultaneously detached from the brush, which is convenient for cleaning the front scraper.

[0012] The liquid spraying assembly is arranged above the rear scraper and is used for applying liquid to the roller brush and / or the surface to be cleaned. The liquid spraying assembly comprises a plurality of liquid outlets and a plurality of flow guide grooves. The plurality of liquid outlets are respectively located in the middle of the plurality of flow guide grooves. Each flow guide groove comprises a plurality of inclined surfaces and is in the shape of a horn expanding outward from the liquid outlet. The inclined surface of each flow guide groove located below the liquid outlet is an arc surface. The inclined surface of the arc surface can improve the uniformity of the output liquid, so as to uniformly wet the roller brush and efficiently clean the floor.

[0013] The liquid spraying assembly is provided with a plurality of comb teeth arranged along the axial direction of the rolling brush.

[0014] Another object of the present application is to provide a cleaning device comprising a body and the above-mentioned floor brush.

[0015] The present application has the beneficial effects that, due to the added squeegee, the squeegee closely contacts the ground when the cleaning device is used to clean the ground, and guides the sewage into the suction port, thereby reducing the possibility of sewage remaining on the ground. In addition, the floor brush of the present application is provided with a front squeegee and a rear squeegee on both sides of the rolling brush, and the front squeegee and the rear squeegee can both abut against the surface to be cleaned, so that when the cleaning device is pushed forward or pulled backward, the squeegee abuts against the surface to be cleaned to guide the liquid and dirt on the surface to be cleaned into the suction port, thereby reducing the sewage remaining on the surface to be cleaned.

[0024] In an embodiment of the present application, the cleaning device 1000 includes but is not limited to a cleaning machine, a vacuum cleaner, a sweeping robot and the like. Taking the cleaning machine as an example, Figure 1 the cleaning machine in the present application includes a floor brush 100 in contact with the surface to be cleaned and a machine body 200 connected with the floor brush 100, and the machine body 200 is provided with functional units such as a suction system and a control system to complete the cleaning work in cooperation with the floor brush 100. For example, when the cleaning machine performs cleaning work, the rolling of the roller brush 110 on the floor brush 100 realizes the function of cleaning the surface to be cleaned. The suction system works to generate negative pressure, and the function of collecting dirt is realized through the floor brush 100. The surface to be cleaned includes the surface of the ground, carpet and sofa, and for the convenience of description, the ground is taken as an example for description below.

[0025] The floor brush 100 further includes a suction port (not shown in the figure), and the machine body 200 is internally provided with a dirt suction channel in communication with the suction port. The cleaning device 1000 can clean the dirt on the ground through the roller brush 110, and suck the dirt on the ground through the suction port, and the sucked dirt enters the dirt suction channel through the suction port.

[0026] Referring to Figure 1 and Figure 2 , the floor brush 100 includes a roller brush 110 rotatable in a predetermined direction, a front scraping strip 120 abuttable with the ground, and a rear scraping strip 130 abuttable with the ground. Along the width direction of the floor brush 100, the front scraping strip 120 and the rear scraping strip 130 are respectively located on both sides of the roller brush 110.

[0027] In an embodiment, as shown in Figure 2 , the front scraping strip 120 and the rear scraping strip 130 are connected through a connecting assembly 140. The floor brush 100 further includes a roller assembly 150 and a transmission device 160, and the transmission device 160 connects the roller assembly 150 and the connecting assembly 140, so that when the roller assembly 150 rotates, the connecting assembly 140 can be driven to move through the transmission device 160. After the front scraping strip 120 and the rear scraping strip 130 are connected, the movement of both the front scraping strip 120 and the rear scraping strip 130 can be realized through one transmission device 160.

[0028] In the embodiment, the floor brush further comprises a cover assembly 170, which is detachably connected with the floor brush 100 and can cover part of the roller brush 110. The connecting assembly 140 is an arc-shaped panel with a hollow portion, which is located below the cover assembly 170 and does not affect the dismounting and mounting of the cover assembly 170. The hollow portion can provide a space for the liquid spraying assembly 180 to spray liquid onto the roller brush 110. The connecting assembly 140 and the cover assembly 170 are independent of each other and have no connection relationship. When the transmission device 160 drives the connecting assembly 140 to move, it will not affect the cover assembly 170, i.e. it will not drive the cover assembly 170 to move. In other embodiments, the connecting assembly can be a connecting strip, which is not limited in specific form as long as it can connect the front and rear scraping strips 120 and 130 and can drive the front and rear scraping strips 120 and 130 to move in cooperation with the transmission device 160.

[0029] Specifically, the transmission device 160 comprises a gear 161, a rack 162, a rotating rod 163, a front limiting block 164 and a rear limiting block 165 opposite to the front limiting block 164 along the width direction of the floor brush 100. The roller assembly 150 comprises two rollers 151 and a connecting rod 152 connecting the two rollers 151. The two rollers 151 are arranged along the length direction of the floor brush 100, so that the connecting rod 152 is parallel to the roller brush 110. The gear 161 is connected with the connecting rod 152. When the rollers 151 rotate, the gear 161 can rotate in the same direction. The rack 162 is engaged with the gear 161. The rotating rod 163 is movably connected with the rack 162 at the end away from the gear 161, and the rotating rod 163 can make reciprocating motion between the front limiting block 164 and the rear limiting block 165. In the embodiment, the rotating rod 163 is movably connected with the rack 162 by a pin. In other embodiments, the pin is not limited to be used for connection, and other conventional ways that can movably connect the two parts can be used. A pivot shaft is arranged at the middle position of the rotating rod 163, so that the rotating rod 163 can pivot around the pivot shaft. When one end of the rotating rod 163 moves forward, the other end of the rotating rod 163 can abut against the rear limiting block 165. When one end of the rotating rod 163 moves backward, the other end of the rotating rod 163 can abut against the front limiting block 164, i.e. the rotating rod 163 can make reciprocating motion between the front limiting block 164 and the rear limiting block 165. The pivot shaft can be connected with the cover assembly 170, so that the pivot shaft does not move with the connecting assembly 140. The front limiting block 164 and the rear limiting block 165 are connected with the connecting assembly 140, so that when a force is applied to the front limiting block 164 and the rear limiting block 165, the connecting assembly 140 can be driven to move. In other embodiments, the structure of the transmission device is not limited to this, and other conventional structures that can drive the connecting assembly to move forward and backward can be used, which will not be described here.

[0030] When the roller 151 rotates forward, i.e. the floor brush 100 moves forward, the gear 161 is driven to rotate forward, at this time, the rack 162 engaged with the gear 161 also moves forward, so that one end of the rotating rod 163 moves forward, and the other end is offset rearward to abut against the rear limiting block 165, and an acting force is given to the rear limiting block 165, so that the connecting assembly 140 moves rearward until the front squeegee 120 is lifted and the rear squeegee 130 abuts against the surface to be cleaned, so as to realize that when the roller 151 rotates forward, the front squeegee 120 is lifted, and the rear squeegee 130 abuts against the surface to be cleaned. At this time, lifting the front squeegee 120 can avoid that the front squeegee 130 prevents the water stains and garbage originally located in front of the front squeegee 130 from entering the suction port when the floor brush 100 moves forward, and the rear squeegee 120 can guide the water stains and garbage in front of the rear squeegee 120 to enter the suction port.

[0031] When the roller 151 rotates backward, i.e. the floor brush 100 moves backward, the gear 161 is driven to rotate backward, at this time, the rack 162 engaged with the gear 161 also moves backward, so that one end of the rotating rod 163 moves backward, and the other end is offset forward to abut against the front limiting block 164, and an acting force is given to the front limiting block 164, so that the connecting assembly 140 moves forward until the rear squeegee 130 is lifted and the front squeegee 120 abuts against the surface to be cleaned, so as to realize that when the roller 151 rotates backward, the rear squeegee 130 is lifted, and the front squeegee 120 abuts against the surface to be cleaned. At this time, lifting the rear squeegee 130 can avoid that the rear squeegee 130 prevents the water stains and garbage originally located behind the rear squeegee 130 from entering the suction port when the floor brush 100 moves backward, and the front squeegee 120 can guide the water stains and garbage in front of the roller 110 to enter the suction port.

[0032] In another embodiment, the floor brush 100 is provided with a first guide rail and a first driving device, the first driving device can drive the front squeegee 120 to move in the first guide rail in the vertical direction; the floor brush 100 is also provided with a second guide rail and a second driving device, the second driving device can drive the rear squeegee 130 to move in the second guide rail in the vertical direction. Two driving devices are used to control the front squeegee 120 and the rear squeegee 130 respectively, so that there is no connection relationship between the front squeegee 120 and the rear squeegee 130, and through electronic control, the resistance to the user is smaller than that in the mechanical control mode of the transmission device 160. At this time, an inertial sensor is arranged on the floor brush 100, and the inertial sensor is in communication with the main control board. The inertial sensor can identify the movement direction of the floor brush 100, so as to send a signal to the main control board, so that the main control board can control whether the first driving device and the second driving device operate according to the signal sent by the inertial sensor.

[0033] When the floor brush 100 moves forward, the inertial sensor senses the movement of the floor brush 100 and sends a signal to the main control board that the floor brush 100 is moving forward. After receiving the signal, the main control board sends a signal to the second driving device to control the movement of the second driving device. After the second driving device is driven, the rear squeegee 130 moves downward along the second guide rail until the rear squeegee 130 abuts against the surface to be cleaned. At the same time, the main control board sends a signal to the first driving device to control the movement of the first driving device. After the first driving device is driven, the front squeegee 120 moves upward along the first guide rail until the front squeegee 120 is away from the surface to be cleaned. At this time, lifting the front squeegee 120 can prevent the front squeegee 130 from preventing the water stains and garbage in front of the front squeegee 130 from entering the suction port when the floor brush 100 moves forward. At the same time, the rear squeegee 120 can guide the water stains and garbage in front of the rear squeegee 120 to enter the suction port.

[0034] When the floor brush 100 moves backward, the inertial sensor senses the movement of the floor brush 100 and sends a signal to the main control board that the floor brush 100 is moving backward. After receiving the signal, the main control board sends a signal to the first driving device to control the movement of the first driving device. After the first driving device is driven, the front squeegee 120 moves downward along the first guide rail until the front squeegee 120 abuts against the surface to be cleaned. At the same time, the main control board sends a signal to the second driving device to control the movement of the second driving device. After the second driving device is driven, the rear squeegee 130 moves upward along the second guide rail until the rear squeegee 130 is away from the surface to be cleaned. At this time, lifting the rear squeegee 130 can prevent the rear squeegee 130 from preventing the water stains and garbage in front of the rear squeegee 130 from entering the suction port when the floor brush 100 moves backward. At the same time, the front squeegee 120 can guide the water stains and garbage in front of the front squeegee 120 to enter the suction port.

[0035] In other embodiments, a sensor such as a gyroscope that can detect the movement direction of the floor brush can also be used, and is not limited to an inertial sensor.

[0036] In the present embodiment, the floor brush 100 further comprises a cover assembly 170, which is detachably connected with the floor brush 100 and can cover part of the roller brush 110. The first guide rail and the front squeegee 120 are arranged on the cover assembly 170. At this time, when the cover assembly 170 is detached, the front squeegee 120 can be simultaneously detached from the floor brush 100, which facilitates the cleaning of the front squeegee 120.

[0037] As Figure 6As shown, the upper part of the rear scraping strip 130 is provided with a liquid spraying assembly 180 for applying liquid to the rolling brush 110 and / or the surface to be cleaned; the liquid spraying assembly 180 comprises a plurality of liquid outlet holes 181 and a plurality of guide grooves 182, and the plurality of liquid outlet holes 181 are respectively located in the middle part of the plurality of guide grooves 182; each guide groove 182 comprises a plurality of inclined surfaces 1821 and is in the shape of a horn expanding outwardly with the liquid outlet hole 181 as the center, wherein the inclined surface 1821 of each guide groove 182 located below the liquid outlet hole 181 is an arc surface. The arc surface is an arc surface with the middle part being low and the two ends being high, that is, the lowest part of the inclined surface 1821 is directly below the liquid outlet hole 181, and gradually rises towards the two ends. The inclined surface 1821 of the arc surface can improve the uniformity of the output liquid, so as to uniformly wet the rolling brush 110 and efficiently complete the floor cleaning. In the embodiment, the plurality of liquid outlet holes 181 are respectively located at the centers of the plurality of guide grooves 182, which is beneficial to the uniform distribution of the sprayed liquid and can make the liquid sprayed from both sides of the liquid outlet hole 181 reach the rolling brush 110 at the same time. In other embodiments, the liquid outlet hole does not need to be arranged at the center, and a slight deviation in any direction can meet the requirements. The arrangement of the horn-shaped guide groove 182 makes the water sprayed from the liquid outlet hole 181 flow along the inclined surface 1821 of the guide groove 182 and finally flow to the rolling brush 110, thereby increasing the dispersibility of the water. The arrangement of the liquid outlet hole 181 in the guide groove 182 can effectively prevent the liquid outlet hole 181 from being blocked, and when the liquid sprayed from the liquid outlet hole 181 is too much, the guide groove 182 can also store some water that is not absorbed by the rolling brush 110, thereby improving the reliability of the rolling brush 110 in use.

[0038] In the embodiment, a plurality of comb teeth 183 are further arranged on the liquid spraying assembly 180 and arranged along the axial direction of the rolling brush 110. The comb teeth 183 are arranged vertically and in the shape of a sawtooth. When the rolling brush 110 rotates, the comb teeth 183 comb the rolling brush 110, which can remove the hair, thread and other filamentary objects wrapped on the rolling brush 110, avoid the filamentary objects from being wrapped on the end part of the rolling brush 110 to adversely affect the rotation of the rolling brush 110, and make the removed hair and other dirt objects more easily sucked into the suction channel through the suction port, thereby improving the cleanliness of the rolling brush 110, avoiding secondary pollution, improving the user experience, and avoiding the user from manually touching the rolling brush 110 to remove the hair.

[0039] As the wiper strips are added, when the cleaning device 1000 is used to clean the surface to be cleaned, the wiper strips are closely attached to the surface to be cleaned and guide the sewage and garbage into the suction port, thereby reducing the possibility of part of the sewage remaining on the surface to be cleaned. In addition, the floor brush 100 of the present application is provided with a front wiper strip 120 and a rear wiper strip 130 on both sides of the roller brush 110, and the front wiper strip 120 and the rear wiper strip 130 can be in abutment with the surface to be cleaned, so that when the cleaning device 1000 is pushed forward or pulled backward, the wiper strip is in abutment with the surface to be cleaned to guide the liquid and other dirt on the surface to be cleaned into the suction port, thereby reducing the sewage remaining on the surface to be cleaned.
