[0002] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Cleaning equipment can use the negative pressure suction generated by high-speed airflow to suck up dust and debris from the ground to achieve floor cleaning.

[0003] In related technologies, cleaning equipment includes a floor brush device that can move on the ground and sweep or pat the ground with a roller brush. It also sucks in the surface to be cleaned or the dirt and debris rolled up by the roller brush through the air intake, thereby cleaning the surface to be cleaned.

[0004] However, when there is a lot of dust on the ground, existing cleaning equipment will leave dust residue after cleaning. Utility Model Content

[0005] This application provides a floor brush device and cleaning equipment to solve the technical problem that existing cleaning equipment leaves dust residue after cleaning when there is a lot of dust on the ground.

[0006] In a first aspect, this application provides a floor brush device, including a device body and a roller brush assembly. The device body has a roller brush cavity and an air inlet, and the roller brush cavity is connected to the air inlet. The roller brush assembly is rotatably disposed in the roller brush cavity. The roller brush cavity has an opening facing downwards from the floor brush device. A ventilation hole is provided at the bottom of the device body, and the ventilation hole connects the outer side of the bottom edge of the device body and the opening.

[0007] The floor brush device provided in this application cleans or pats the surface to be cleaned by means of a roller brush assembly, and sucks in stains and debris from the surface through an air inlet, thereby achieving cleaning of the surface. The bottom of the main body of the floor brush device has ventilation holes that connect the outer edge of the bottom edge of the main body to the opening of the roller brush chamber. When the air inlet is drawing air, the ventilation holes can increase the airflow, thereby improving suction efficiency and reducing dust residue.

[0008] As an optional implementation, the airflow direction within the ventilation hole is horizontal.

[0009] This setup allows for more stable airflow, thereby improving dust absorption efficiency.

[0010] As an optional implementation, the ventilation holes include a first ventilation hole and a second ventilation hole, which are located on different sides of the device body.

[0011] This design allows dust from different sides of the device body to be drawn in through the first and second ventilation holes, improving the cleaning effect.

[0012] As an optional implementation, along the cleaning direction of the floor brush device, the first ventilation hole is located on the front side of the roller brush cavity; there are at least two second ventilation holes, and at least two second ventilation holes are arranged on both sides of the width direction of the device body.

[0013] With this configuration, dust can be drawn in from the front and both sides of the main body of the device through the first and second ventilation holes, thus improving cleaning efficiency.

[0014] As an optional implementation, the cross-sectional area of ​​the second ventilation hole is 1%-30% of the cross-sectional area of ​​the first ventilation hole.

[0015] This design increases the ventilation area of ​​the first ventilation hole, improving the dust absorption efficiency of the floor brush device when dealing with large amounts of dust.

[0016] As an optional implementation, the sidewall of the first ventilation hole forms an angle with the cleaning direction of the floor brush device, and the cross-sectional area of ​​the air inlet end of the first ventilation hole is larger than the cross-sectional area of ​​the air outlet end.

[0017] This design, with its gradually changing airflow structure, can guide airflow more efficiently and improve dust collection efficiency.

[0018] As an optional implementation, the ventilation direction of the second ventilation hole is at an angle to both the width direction and the cleaning direction of the floor brush device, and the air inlet of the second ventilation hole is located in front of the air outlet.

[0019] This design directs the airflow from the second ventilation hole toward the air intake, making it easier for dust to be drawn in.

[0020] As an optional implementation, when the air intake is drawing air, the inflow direction of the airflow through the first ventilation hole forms an angle with the inflow direction of the airflow through the second ventilation hole.

[0021] This design allows for the disturbance of airflow within the brush chamber by two streams of air, preventing the brush assembly from tangling with hair.

[0022] As an optional implementation, the cross-sectional shape of the ventilation hole is polygonal.

[0023] This design facilitates the design of ventilation holes and allows for optimization of the flow channel structure, thereby optimizing the airflow direction of the ventilation holes.

[0024] As an optional implementation, the main body of the device includes an upper shell and a lower shell, with the upper shell connected above the lower shell; ventilation holes are provided in the lower shell, and the height of the ventilation holes is less than or equal to the height of the lower shell.

[0025] This setup increases the airflow through the ventilation openings while ensuring they have strong suction.

[0026] As an alternative implementation, the roller brush assembly includes a roller and a scraper, the roller having a through groove, and the scraper being configured to be inserted into the through groove and connected to the roller.

[0027] The roller has multiple connecting holes, which are spaced apart along the length of the roller; the area of ​​the connecting holes is 1%-99% of the area of ​​the roller brush assembly.

[0028] This design, through multiple connecting holes, can disrupt the airflow around the roller brush assembly, preventing the roller brush from being entangled by hair.

[0029] Secondly, this application provides a cleaning device, which includes the aforementioned floor brush device.

[0030] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body and a roller brush assembly. The main body has a roller brush cavity and an air intake, with the roller brush cavity communicating with the air intake. The roller brush assembly is rotatably disposed in the roller brush cavity. The roller brush cavity has an opening facing downwards from the floor brush device. A ventilation hole is provided at the bottom of the main body, connecting the outer side of the bottom edge of the main body to the opening. When the air intake is drawing air, the ventilation hole can increase the airflow, thereby improving the suction efficiency and reducing dust residue.

[0048] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Cleaning equipment can use the negative pressure suction generated by high-speed airflow to suck up dust and debris from the ground to achieve floor cleaning.

[0049] In related technologies, cleaning equipment includes a floor brush device that can move on the ground and sweep or pat the ground with a roller brush. It also sucks in the surface to be cleaned or the dirt and debris rolled up by the roller brush through the air intake, thereby cleaning the surface to be cleaned.

[0050] However, when there is a lot of dust on the ground, existing cleaning equipment will leave dust residue after cleaning.

[0051] To address the aforementioned technical problems, this application provides a floor brush device and cleaning equipment. The floor brush device includes a roller brush assembly and a suction port. The roller brush assembly can sweep or pat the surface to be cleaned, and works in conjunction with the suction port to suck up stains and debris from the surface, thus achieving cleaning. The bottom of the main body of the floor brush device has a ventilation hole connecting the outer edge of the bottom edge of the main body to the opening of the roller brush chamber. When the suction port is in operation, the ventilation hole increases the airflow, thereby improving suction efficiency and reducing dust residue.

[0052] In addition, the airflow from the vent can quickly deliver hair fibers to the air intake, reducing the chance of hair fibers getting tangled in the roller brush.

[0053] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.

[0054] The floor brush device provided in this application embodiment is applied to cleaning equipment. The types of products to which the floor brush device can be applied include, but are not limited to, vacuum cleaners, mite removers, floor scrubbers, etc. Depending on the different product types, the cleaning equipment provided in this application embodiment can be used to clean hard surfaces of various materials, such as floors and floor tiles, and can also be used to clean soft surfaces of various materials, such as sofas and carpets. This application embodiment does not make specific limitations in this regard.

[0056] Reference Figures 1 to 4 As shown, this application provides a floor brush device 100, which can move on the surface to be cleaned and clean it. The cleaning equipment includes a main body and a floor brush device 100, which is connected to the main body and contacts the surface to be cleaned. The floor brush device 100 includes a main body 110 and a roller brush assembly 120. The main body 110 has a roller brush cavity 111 and an air intake 112, which communicate with the air intake 112. The roller brush assembly 120 is rotatably disposed in the roller brush cavity 111.

[0057] Reference Figure 2 The direction of movement of the floor brush device 100 during cleaning is defined as the Y direction, and the width direction of the device body 110 is defined as the X direction, which is perpendicular to the Y direction.

[0058] Along the cleaning direction of the floor brush device 100, the suction port 112 can be located at the rear of the roller brush assembly 120. The main body of the device is equipped with a suction unit and a suction channel, and the suction port 112 is connected to the suction unit through the suction channel. During cleaning, the roller brush assembly 120 rotates and pats or scrapes the surface to be cleaned. At the same time, the suction unit is activated, which creates negative pressure in the suction channel, thereby causing the suction port 112 to generate suction. The suction port 112 can suck in the surface to be cleaned as well as dust, hair, debris and other garbage and debris rolled up by the roller brush assembly 120. The garbage and debris enter the garbage collection device in the main body of the device through the suction channel.

[0059] It should be noted that the roller brush chamber 111 has an opening 1111 facing downwards from the floor brush device 100. The bottom of the device body 110 is provided with a ventilation hole 113, which connects the outer side of the bottom edge of the device body 110 and the opening 1111. Since the suction port 112 is connected to the roller brush chamber 111, when the suction port 112 draws air, a negative pressure is generated in the roller brush chamber 111, allowing airflow to enter the roller brush chamber 111 through the ventilation hole 113. When the floor brush device 100 moves to the dust accumulation area, the ventilation hole 113 can quickly draw in the dust from the outer side of the bottom edge of the device body 110, thereby reducing the cleaning pressure of the roller brush assembly 120 and preventing dust residue after cleaning.

[0060] It is understood that the ventilation hole 113 is located at the bottom of the device body 110 and is used to connect the outer side of the bottom edge of the device body 110 and the opening 1111 of the roller brush cavity 111. The airflow channel of the ventilation hole 113 is formed by the surface to be cleaned and the wall surface of the device body 110. When the airflow flows in the ventilation hole 113, the flow direction is horizontal or forms a small angle with the horizontal direction. The airflow is more stable when it flows through the ventilation hole 113, which can improve the suction efficiency of the ventilation hole 113 and increase the absorption efficiency of dust.

[0061] Among them, the horizontal direction is Figure 2 Any direction in the plane formed by the X and Y directions, i.e., the horizontal direction is parallel to the surface to be cleaned; the vertical direction is perpendicular to the surface to be cleaned, and the vertical direction is perpendicular to the horizontal direction.

[0062] As one possible implementation, the ventilation hole 113 includes a first ventilation hole 1131 and a second ventilation hole 1132, with the first ventilation hole 1131 and the second ventilation hole 1132 located on different sides of the device body 110.

[0063] It is understandable that when the floor brush device 100 moves on a dusty surface to be cleaned, there is generally dust in all directions of the floor brush device 100. By setting the first ventilation hole 1131 and the second ventilation hole 1132 on different sides of the device body 110, some of the dust around the device body 110 can be sucked in in advance, reducing the subsequent cleaning pressure and improving cleaning efficiency and cleaning effect.

[0064] As one possible implementation, along the cleaning direction of the floor brush device 100, the first ventilation hole 1131 is located on the front side of the roller brush cavity 111; there are at least two second ventilation holes 1132, and at least two second ventilation holes 1132 are arranged on both sides of the width direction of the device body 110.

[0065] It should be noted that the first ventilation hole 1131 extends along the width direction of the main body 110 of the device, and the length of the first ventilation hole 1131 can be 60%-85% of the width of the main body 110 of the device. When the floor brush device 100 moves along the cleaning direction, the first ventilation hole 1131 can first suck in a portion of the dust, then the roller brush assembly 120 further pats or scrapes the surface to be cleaned, and finally the suction port 112 directly sucks up the dust from the surface to be cleaned. In this way, through three-stage cleaning, even if there is a lot of dust accumulated on the surface to be cleaned, the floor brush device 100 has a good cleaning effect and avoids dust residue.

[0066] In some embodiments, the first ventilation hole 1131 can be configured to be relatively flat, so that the airflow velocity in the first ventilation hole 1131 is greater, the suction is enhanced, and the dust absorption efficiency is higher.

[0067] It is understandable that, since the first ventilation hole 1131 is located on the bottom surface of the device body 110, the airflow is close to the surface to be cleaned when it flows through the first ventilation hole 1131, and the airflow direction is opposite to the Y direction. When the roller brush assembly 120 rotates, the instantaneous rotation direction of the part of the roller brush assembly 120 that contacts the surface to be cleaned is consistent with the airflow direction. When hair is about to wrap around the roller brush along the rotation direction of the roller brush, the high-speed airflow of the first ventilation hole 1131 will bring the hair into the suction port, thereby reducing the probability of hair wrapping around the roller brush.

[0068] It should be noted that at least one second ventilation hole 1132 is provided on each side of the main body 110 in the width direction. Along the cleaning direction of the floor brush device 100, the second ventilation hole 1132 can be located on the front or rear side of the roller brush assembly 120, or in other positions. This application embodiment does not make specific limitations. When the floor brush assembly moves along the cleaning direction, the second ventilation hole 1132 will also generate a strong suction force, sucking in some dust from both sides of the main body 110, thus improving the cleaning effect.

[0069] As one possible implementation, the cross-sectional area of ​​the second ventilation hole 1132 is 1%-30% of the cross-sectional area of ​​the first ventilation hole 1131.

[0070] It is understandable that the cross-sectional area of ​​each second ventilation hole 1132 is 1%-30% of the cross-sectional area of ​​the first ventilation hole 1131. The first ventilation hole 1131 plays a major role in improving the dust collection effect of the floor brush device 100. The first ventilation hole 1131, together with the roller brush assembly 120 and the air intake 112, has a good cleaning effect on the dust on the moving path of the floor brush device 100, which can prevent dust residue from increasing the cleaning workload.

[0071] For example, the cross-sectional area of ​​the second ventilation hole 1132 can be 1%, 5%, 10%, 15%, 25%, 29%, 30% of the cross-sectional area of ​​the first ventilation hole 1131, etc., and this application embodiment does not make specific limitations.

[0072] It should be noted that the sidewall of the first ventilation hole 1131 forms an angle with the cleaning direction of the floor brush device 100, and the cross-sectional area of ​​the air inlet of the first ventilation hole 1131 is larger than the cross-sectional area of ​​the air outlet. (Refer to...) Figure 2Along the cleaning direction of the floor brush device 100, the air inlet of the first ventilation hole 1131 is located in front of the air outlet. From the air inlet to the air outlet, the cross-sectional area of ​​the first ventilation hole 1131 gradually decreases, allowing it to guide airflow more efficiently and achieve better dust collection. The wider air inlet of the first ventilation hole 1131 increases the suction area, while the narrower air inlet increases the air velocity and enhances suction. The sidewall extension line of the first ventilation hole 1131 can extend to the air intake 112, allowing airflow to enter the air intake 112 more efficiently.

[0073] It should be noted that the ventilation direction of the second ventilation hole 1132 is at an angle to both the width direction and the cleaning direction of the floor brush device 100. Furthermore, along the cleaning direction of the floor brush device 100, the air inlet of the second ventilation hole 1132 is located in front of the air outlet. Thus, the extension line of the airflow direction of the second ventilation hole 1132 can extend to the air intake 112, making it easier for the airflow to carry dust into the air intake 112.

[0074] The two side walls of the second ventilation opening can be arranged in parallel or not, so that the cross-sectional area of ​​the air inlet end of the second ventilation hole 1132 is larger than the cross-sectional area of ​​the air outlet end, so that the second ventilation hole 1132 can guide the airflow more efficiently and has better dust collection.

[0075] It is understandable that when the air intake 112 draws air, the airflow direction of the first ventilation hole 1131 is opposite to or approximately opposite to the Y direction, and the airflow direction of the second ventilation hole 1132 has an angle with the Y direction. Therefore, the airflow direction of the first ventilation hole 1131 and the airflow direction of the second ventilation hole 1132 have an angle. The two airflows can disturb the airflow in the roller brush cavity 111 and prevent the roller brush assembly 120 from getting tangled in hair.

[0076] As one possible implementation, the cross-sectional shape of the ventilation hole 113 is polygonal.

[0077] The cross-sectional shape of the first ventilation hole 1131 can be trapezoidal or rectangular, etc., and the cross-sectional shape of the second ventilation hole 1132 can be parallelogram or trapezoidal, etc.

[0078] As one possible implementation, the main body 110 includes an upper housing 114 and a lower housing 115, with the upper housing 114 connected above the lower housing 115; a ventilation hole 113 is provided in the lower housing 115, and the height of the ventilation hole 113 is less than or equal to the height of the lower housing 115.

[0079] It should be noted that the upper housing 114 and the lower housing 115 can be fixedly connected or detachably connected. After the upper housing 114 and the lower housing 115 are connected, a brush cavity 111 is formed, and the opening 1111 of the brush cavity 111 is surrounded by the bottom edge of the lower housing 115. The first ventilation hole 1131 and the second ventilation hole 1132 are formed by the bottom notch of the lower housing 115, and the vertical height of the first ventilation hole 1131 and the second ventilation hole 1132 is less than or equal to the height of the lower housing 115. In some embodiments, in order to ensure the ventilation area and increase the gas flow rate of the ventilation hole 113, the vertical height of the first ventilation hole 1131 and the second ventilation hole 1132 can be 3mm.

[0080] Reference Figure 5 , combined Figure 1 and Figure 2 As one possible implementation, the roller brush assembly 120 includes a roller 121 and a scraper 123. The roller 121 is provided with a through groove 1212b, and the scraper 123 is configured to be inserted into the through groove 1212b and connected to the roller 121. The roller 121 is provided with a plurality of connecting holes 1212a, which are arranged at intervals along the length of the roller 121. The area of ​​the connecting holes 1212a is 1%-99% of the area of ​​the roller brush assembly 120.

[0081] It should be noted that the roller 121 extends along the width direction of the device body 110, and the length direction of the roller 121 is the width direction of the device body 110. The roller 121 includes at least one scraping element 123. When the roller 121 rotates, the scraping element 123 contacts and pats the surface to be cleaned.

[0082] For example, the roller 121 includes a roller body 1211 and at least one connecting structure 1212. The connecting structure 1212 and the roller body 1211 are integrally formed. One end of the connecting structure 1212 away from the surface of the roller body 1211 is provided with a through groove 1212b. The through groove 1212b extends along the length direction of the roller 121. The scraping member 123 can be a rubber strip with a protrusion 1231. The protrusion 1231 of each rubber strip can be inserted through the through groove 1212b of a connecting structure 1212, so that the rubber strip and the connecting structure 1212 are detachably connected.

[0083] Each connection structure 1212 is provided with multiple connecting holes 1212a. The connecting holes 1212a can be elliptical, circular, or square, etc. The number of connecting holes 1212a can be 2, 3, 4, 5, etc., and this application embodiment does not make a specific limitation.

[0084] It should be noted that the connecting hole 1212a penetrates the connecting structure 1212 in the first direction and forms an angle with the axial direction of the roller 121. The cross-section of the connecting hole 1212a can be parallel to the axial direction of the roller 121 or form an angle other than 90 degrees, so that the airflow direction through the connecting hole 1212a can be any direction other than parallel to the axial direction of the roller 121. When the suction port 112 draws air, the airflow can flow through the circumference of the roller 121 on the one hand, and through the air path formed by the connecting hole 1212a on the other hand, so that the circumference of the roller 121 and the connecting hole 1212a can both form air paths for airflow, improving the air volume and airflow efficiency. In addition, the connecting hole 1212a reduces wind resistance and improves the airflow path in the roller brush cavity 111, thereby preventing hair fibers from getting tangled on the roller brush assembly 120, making it easier for hair fibers to be drawn into the suction port 112.

[0085] For example, the first direction and the axial direction of the roller 121 are both at an angle, and the angle value ranges from 0° to 90°, including but not limited to 1°, 2°, 10°, 20°, 30°, 45°, 60°, 89°, etc. The embodiments of this application do not specifically limit this.

[0086] This application provides a floor brush device 100 and a cleaning device. The floor brush device 100 includes a device body 110 and a roller brush assembly 120. The device body 110 has a roller brush cavity 111 and an air intake 112, with the roller brush cavity 111 communicating with the air intake 112. The roller brush assembly 120 is rotatably disposed in the roller brush cavity 111. The roller brush cavity 111 has an opening 1111 facing downwards from the floor brush device 100. A ventilation hole 113 is provided at the bottom of the device body 110, connecting the outer side of the bottom edge of the device body 110 and the opening 1111. When the air intake 112 draws air, the ventilation hole 113 can increase the airflow, thereby improving the suction efficiency and reducing dust residue.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
