[0004] Therefore, it is urgent to solve the technical problem that hair is easy to wrap on the roller brush during the use of the cleaning equipment, affecting the cleaning effect. UTILITY MODEL CONTENT

[0005] The utility model provides a floor brush structure and cleaning equipment, with solve cleaning equipment in the course of using, easy to appear hair winding on the roller brush, affect the technical problem of cleaning effect.

[0006] In order to realize the above-mentioned purpose, the utility model provides a floor brush structure, including:

[0007] The shell has a roller brush cavity and a suction passage in the shell, the roller brush cavity includes a mounting space and a rectification space, the bottom of the shell has a dust suction port communicated with the roller brush cavity;

[0008] The roller brush is rotationally arranged in the mounting space;

[0009] The rectification space is formed between the side of the roller brush away from the dust suction port and the inner wall of the roller brush cavity, and the rectification space is communicated between the mounting space and the suction passage;

[0010] In the cross section perpendicular to the axial direction of the roller brush, the cross-sectional area S of the rectification space and the cross-sectional area S1 of the roller brush cavity satisfy: 1%≤S / S1≤90%.

[0011] The floor brush structure provided by the utility model embodiment forms a rectification space between the side of the roller brush away from the dust suction port and the inner wall of the roller brush cavity, increases the volume of the roller brush cavity, the rectification space can reduce the problem of reducing the cleaning suction caused by the contact between the roller brush and the roller brush cavity, and can prevent the hair from contacting the roller brush cavity after entering the roller brush cavity, thereby reducing the problem of hair winding the roller brush.

[0012] Since the rectification space is in communication between the installation space and the air suction channel, the rectification space provides a buffer area, so that the dust and sundries entering the roller brush cavity from the dust suction port can be buffered in the rectification space, and the suction force of the air suction channel on the dust and sundries in the rectification space can reduce the contact of the dust and sundries entering the roller brush cavity with the surface of the roller brush, thereby effectively reducing the problem of hair and sundries winding around the surface of the roller brush, ensuring the cleaning effect of the cleaning equipment, improving the cleaning efficiency of the cleaning equipment, and reducing the cleaning difficulty of the roller brush.

[0013] In addition, in the cross section perpendicular to the axial direction of the roller brush, the cross-sectional area S of the rectification space and the cross-sectional area S1 of the roller brush cavity satisfy: 1%≤S / S1≤90%, which improves the buffering effect of dust and sundries entering the rectification space while not affecting the suction force of the cleaning equipment and the overall size of the cleaning equipment.

[0015] The distance between the second end of the scraping strip and the rotation center line of the roller brush is H1, and the distance between the rotation center line of the roller brush and the bottom of the shell is H2, where H2≤H1. The bottom of the scraping strip can protrude from the bottom of the shell, which is beneficial to the scraping strip to contact the surface to be cleaned. By protruding at least part of the roller brush from the dust suction port and contacting the surface to be cleaned, the contact effect of the roller brush on the soft material to be cleaned can be improved, and the cleaning effect on the soft material to be cleaned can be improved.

[0017] Such a structure lowers the rotation center line of the roller brush, which can increase the contact area of the roller brush with the surface to be cleaned. This design helps to enhance the cleaning ability of the roller brush on dust and sundries on the surface to be cleaned, especially when dealing with uneven surfaces such as carpets. The lowered rotation center line of the roller brush optimizes the contact angle of the roller brush with the uneven surface, which helps to clean hard-to-reach areas such as edges and corners.

[0019] In a possible implementation, the rolling brush cavity is a second rolling brush cavity, and the central axis of the second rolling brush cavity coincides with the rotation center line of the rolling brush. The rotation of the rolling brush in the second rolling brush cavity is symmetrical, which is beneficial to the balance and stability of the rolling brush structure.

[0020] In a possible implementation, the inner wall surface of the rolling brush cavity is in a circular arc shape or a polygonal shape. The circular arc shape of the inner wall surface of the rolling brush cavity can reduce the air flow resistance, thereby improving the suction efficiency. The inner wall surface of the rolling brush cavity is in a polygonal shape, which can generate an additional disturbance effect when the rolling brush rotates, helping to loosen stubborn dust and sundries and improving the cleaning effect.

[0021] In a possible implementation, the bottom of the shell has a bottom plate, the bottom plate blocks the edge of the rolling brush, and the dust suction opening is arranged in the bottom plate. The bottom plate plays a certain blocking role on the rolling brush, which can prevent the rolling brush from coming out.

The setting of the teeth can improve the ability to capture and guide dust, hair and other sundries, and the gap between the teeth helps to prevent the dust suction opening from being blocked.

[0054] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the protection scope of the utility model.

[0055] In the traditional cleaning equipment, it is sometimes difficult to completely remove the hair embedded in the fiber by simply relying on the suction force and the action of the roller brush, and it also causes the hair to entangle the roller brush, affecting the cleaning effect of the roller brush, especially for carpets and similar soft surfaces, the dust removal effect for the dust and other sundries inside the fiber is poor.

[0056] Therefore, the brush structure and the cleaning equipment provided by the utility model can improve the contact effect of the roller brush and the soft material to be cleaned, so that the cleaning effect of the soft material to be cleaned is improved. By increasing the volume of the roller brush cavity, a rectification space is formed between the side of the roller brush opposite to the dust suction port and the inner wall of the roller brush cavity. The rectification space can reduce the problem of reducing the cleaning suction force caused by the contact between the roller brush and the roller brush cavity, and can prevent the hair from entering the roller brush cavity and contacting the roller brush cavity, thereby reducing the problem of hair entanglement.

[0057] The ground brush structure and the cleaning equipment are described below with reference to the drawings.

[0058] Reference Figure 1 And Figure 2 The utility model discloses a ground brush structure, comprising:

[0059] The shell 10 has a rolling brush cavity and a suction passage 12 in the shell 10, the rolling brush cavity includes a mounting space and a rectification space 14, and the bottom of the shell 10 is provided with a dust suction port 13 communicated with the rolling brush cavity.

[0060] The rolling brush 20 is rotatably arranged in the mounting space.

[0061] The rectification space 14 is formed between the side of the rolling brush 20 away from the dust suction port 13 and the inner wall of the rolling brush cavity, and the rectification space 14 is communicated between the mounting space and the suction passage 12.

[0062] In the cross section perpendicular to the axial direction of the rolling brush 20, the cross-sectional area S of the rectification space 14 and the cross-sectional area S1 of the rolling brush cavity satisfy: 1%≤S / S1≤90%.

[0063] The utility model discloses a ground brush structure, by being formed rectification space 14 between the side of the rolling brush 20 away from the dust suction port 13 and the inner wall of the rolling brush cavity, increase the volume of rolling brush cavity, rectification space 14 can reduce the problem that the cleaning preparation suction force reduces because the rolling brush 20 is in contact with the rolling brush cavity, simultaneously, can prevent the hair from entering the rolling brush cavity and being in contact with the rolling brush cavity, reduce the problem that the hair is wound on the rolling brush 20, improve the cleaning effect.

[0064] Under the action of the suction force provided by the motor, the movement direction of the air in the ground brush structure is indicated by the direction of the dotted arrow in the drawings. Figure 1 And Figure 2 The dotted arrow in the drawings indicates the direction.

[0065] In the embodiment, the mounting space is the space in the rolling brush cavity occupied by the rolling brush 20.

[0066] Since the rectification space 14 is communicated between the mounting space and the suction passage 12, the rectification space 14 provides a buffer area, so that the dust and sundries entering the rolling brush cavity from the dust suction port 13 can be buffered in the rectification space 14, and the suction force of the suction passage 12 on the dust and sundries in the rectification space 14 reduces the contact between the dust and sundries entering the rolling brush cavity and the surface of the rolling brush 20, thereby effectively reducing the problem that the hair and sundries are wound on the surface of the rolling brush 20, ensuring the cleaning effect of the cleaning equipment, improving the cleaning efficiency of the cleaning equipment, and reducing the cleaning difficulty of the rolling brush 20.

[0067] In addition, in the cross section perpendicular to the axial direction of the rolling brush 20, the cross-sectional area S of the flow regulation space 14 and the cross-sectional area S1 of the rolling brush cavity satisfy: 1%≤S / S1≤90%. While improving the buffering effect of dust and sundries entering the flow regulation space 14, the suction force of the cleaning device and the overall size of the cleaning device are not affected.

[0068] The flow regulation space 14 is connected between the installation space and the air suction channel 12, so that the air suction channel 12 can exert a suction force on the dust and sundries in the flow regulation space 14. This design ensures that the dust and sundries can be quickly sucked into the air suction channel 12 after entering the flow regulation space 14, rather than remaining in the rolling brush cavity, preventing the dust and sundries from detaching from the surface of the rolling brush 20, ensuring the efficiency of the cleaning process and reducing the maintenance requirements.

[0069] If S / S1 is too small, it means that the buffering area of dust and sundries in the flow regulation space 14 is too small, which can cause dust and sundries to have insufficient space for buffering and dispersion when entering the flow regulation space 14, resulting in the problem of dust and sundries winding around the rolling brush 20, and reducing the overall cleaning efficiency of the cleaning device. If S / S1 is too large, it means that the cross-sectional area S of the flow regulation space 14 is too large, which can cause the suction force in the flow regulation space 14 to be dispersed, thereby reducing the suction capacity of the air suction channel 12 for dust and sundries, affecting the cleaning effect of the cleaning device, and in addition, increasing the overall size of the brush structure, which is not conducive to improving the flexibility of use. By making 1%≤S / S1≤90%, the buffering effect of dust and sundries entering the flow regulation space 14 is improved, while the suction force of the cleaning device and the overall size of the cleaning device are not affected.

[0070] In one possible implementation, in the cross section perpendicular to the axial direction of the rolling brush 20, the ratio of the cross-sectional area S of the flow regulation space 14 to the cross-sectional area S1 of the rolling brush cavity, S / S1, can be, for example, 1%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 85%, or 90%.

[0071] In one possible implementation, at least part of the rolling brush 20 protrudes from the dust suction port 13 and contacts the surface to be cleaned. By having at least part of the rolling brush 20 protrude from the dust suction port 13 and contact the surface to be cleaned, the contact effect of the rolling brush 20 with the soft material to be cleaned can be improved, and the cleaning effect on the soft material to be cleaned can be improved.

[0072] In one possible implementation, with reference to Figure 3 , Figure 4 and Figure 5As shown, the surface of the rolling brush 20 has at least one scraping strip 30, the first end of the scraping strip 30 is connected to the outer wall surface of the rolling brush 20, and the second end of the scraping strip 30 extends along the radial direction of the rolling brush 20; the distance between the second end of the scraping strip 30 and the rotation center line of the rolling brush 20 is H1, and the distance between the rotation center line of the rolling brush 20 and the bottom of the shell 10 is H2, wherein H2≤H1. So that the bottom of the scraping strip 30 can protrude from the bottom of the shell 10, which is beneficial to the scraping strip 30 to contact the surface of the object to be cleaned more.

[0073] In a possible implementation manner, the number of the scraping strips 30 can be 2, 3 or more, which are arranged at intervals along the circumferential direction of the rolling brush 20.

[0074] In a possible implementation manner, the scraping strip 30 can be in a strip shape, and the scraping strip 30 can be arranged in a spiral shape along the outer circumferential surface of the rolling brush 20 or arranged on the outer circumferential surface of the rolling brush 20 along the axial direction of the rolling brush 20. The scraping strip 30 is a flexible member, which is soft and elastic.

[0075] During the rotation of the rolling brush 20, the scraping strip 30 contacts the surface of the object to be cleaned and performs a beating action on the object to be cleaned. When the object to be cleaned is a soft material such as a carpet, a sponge or the like, the dust and sundries hidden inside the object to be cleaned can be shaken out through the beating action. Such physical beating can effectively loosen the deep dust, so that the dust, hair and other impurities inside the soft material are more easily cleaned by the cleaning equipment, thereby improving the cleaning effect. When the object to be cleaned is a hard material such as a floor or the like, the scraping strip 30 can also provide auxiliary cleaning action, which helps to remove stubborn stains through physical beating and scraping action, thereby improving the cleaning effect.

[0076] The rolling brush structure provided by the embodiment of the utility model can provide double cleaning effects in the cleaning process through the cooperation of the scraping strip 30 and the rolling brush 20. The rolling brush 20 can sweep away the dust and sundries on the surface of the object to be cleaned, and the scraping strip 30 can achieve the effect of deep cleaning, thereby improving the cleaning effect.

[0077] In a possible implementation manner, referring to Figure 1 As shown, the rolling brush cavity is a first rolling brush cavity 111, and the center axis of the first rolling brush cavity 111 and the rotation center line of the rolling brush 20 have a distance, that is, the center axis of the first rolling brush cavity 111 and the rotation center line of the rolling brush 20 do not coincide, and the rotation center line of the rolling brush 20 is located on the side of the center axis of the first rolling brush cavity 111 close to the dust collection port 13. That is, the rotation center line of the rolling brush 20 is located on the lower side of the center axis of the first rolling brush cavity 111, and the rolling brush 20 is arranged eccentrically in the first rolling brush cavity 111. Such a structure makes the dust and sundries enter the second rolling brush cavity 112 from the side of the axial direction of the rolling brush 20.

[0078] The rotation center line of the rolling brush 20 can be lowered to increase the contact area between the rolling brush 20 and the surface to be cleaned. This design helps to enhance the cleaning ability of the rolling brush 20 on the dust and debris on the surface to be cleaned, especially when dealing with uneven surfaces such as carpets. The rotation center line of the rolling brush 20 is lowered, which optimizes the contact angle between the rolling brush 20 and the uneven surface, and helps to clean the edges and corners that are difficult to reach.

[0079] In one possible implementation, in the cross section perpendicular to the axial direction of the rolling brush 20, the coordinate axis is drawn with the center axis of the first rolling brush cavity 111 as the coordinate center, the middle line of the coordinate axis is O, the X axis is along the horizontal direction, and the Y axis is along the vertical direction. The rotation center line of the rolling brush 20 can be located in the third quadrant or the fourth quadrant, so that the center of gravity of the brush structure is lower, which helps to improve the stability and maneuverability of the brush structure.

[0080] In one possible implementation, the rotation center line of the rolling brush 20 can be located in the third quadrant, which means that the rotation center line of the rolling brush 20 is located below and to the left of the center axis of the first rolling brush cavity 111. This position can optimize the contact angle between the rolling brush 20 and the ground, especially when the cleaning device moves forward, so that the rolling brush 20 can better grab and clean the dust and other debris on the ground. Of course, the rotation center line of the rolling brush 20 can also be located in the fourth quadrant or on the -Y axis. This arrangement can enhance the cleaning effect when the cleaning device moves backward, especially on the surface to be cleaned that needs to be cleaned repeatedly forward and backward, the cleaning effect is better.

[0081] In one possible implementation, the air suction channel 12 has an air suction port 121 located on the inner wall of the side of the first rolling brush cavity 111 close to the dust suction port 13. This layout optimizes the airflow path and reduces airflow resistance, so that the air suction port 121 can more effectively capture dust and other debris entering the first rolling brush cavity 111, reducing the possibility of dust circulating and secondary pollution inside the device.

[0082] In addition, the location of the air suction port 121 close to the dust suction port 13 can ensure that dust and other debris are more easily sucked into the air suction channel 12 after entering the first rolling brush cavity 111, reducing the residence time of the debris in the rolling brush cavity, thereby improving the efficiency of the suction force and reducing the problem of the rolling brush 20 being entangled.

[0083] In one possible implementation, referring to Figure 2 The rolling brush cavity is the second rolling brush cavity 112, and the center axis of the second rolling brush cavity 112 coincides with the rotation center line of the rolling brush 20. The rotation of the rolling brush 20 in the second rolling brush cavity 112 is symmetrical, which is beneficial to maintaining the balance and stability of the brush structure. In such a structure, dust and other debris can enter the second rolling brush cavity 112 from both sides of the axial direction of the rolling brush 20.

[0084] In a possible implementation, the inner wall surface of the rolling brush cavity is in a circular arc shape or a polygonal shape. The inner wall surface of the rolling brush cavity in a circular arc shape can reduce air flow resistance, thereby improving the suction efficiency. The inner wall surface of the rolling brush cavity in a polygonal shape can generate an additional disturbance effect when the rolling brush 20 rotates, which helps to loosen stubborn dust and debris and improves the cleaning effect.

[0085] In a possible implementation, as shown in Figure 3 and Figure 4 , the bottom of the shell 10 has a bottom plate 50, which blocks the edge of the rolling brush 20, and the dust suction port 13 is arranged in the bottom plate 50.

[0086] The bottom plate 50 blocks the rolling brush 20 to a certain extent, which can prevent the rolling brush 20 from coming out. Part of the structure of the rolling brush 20 protrudes from the bottom of the shell 10 through the dust suction port 13, which helps to ensure that the scraping strip 30 arranged on the rolling brush 20 contacts the surface to be cleaned, thereby improving the cleaning effect.

[0087] In a possible implementation, the inner wall of the dust suction port 13 has a plurality of spaced teeth 131, the teeth 131 extend into the dust suction port 13, and the gap 132 between adjacent two teeth 131. The plurality of teeth 131 are arranged in a comb shape, and dust and other debris can enter the rolling brush cavity through the gap 132 between adjacent two teeth 131.

[0088] By designing a plurality of spaced teeth 131 on the inner wall of the dust suction port 13, dust, hair and other debris can be effectively captured and guided. The gap 132 between the teeth 131 helps to prevent the dust suction port 13 from being blocked. Debris can enter the rolling brush cavity through the gap 132 between adjacent two teeth 131, without accumulating at the dust suction port 13, thereby maintaining the continuous suction of the cleaning device and the cleaning efficiency.

[0089] The teeth 131 can also help to loosen the dust and hair on the fiber surface. Especially when cleaning the surface of the carpet or fabric, the teeth 131 can play a role in preliminary combing and dispersing dust and hair, thereby improving the deep cleaning ability of the cleaning device, facilitating the suction of debris and hair, and reducing the entanglement of hair and fibers on the rolling brush 20.

[0090] In a possible implementation, the number of teeth 131 and the size of the gap 132 between adjacent two teeth 131 are not limited here.

[0091] In a possible implementation, as shown in Figure 1 , Figure 2 and Figure 7 , the dust suction port 13 is arranged on the bottom plate 50 of the shell 10, and the dust suction port 13 is arranged on the bottom plate 50 of the shell 10.As shown, the housing 10 comprises a lower shell 15 and an upper cover 16 which are buckled to each other, the roller brush cavity can be formed by upwardly recessing the bottom of the lower shell 15, and the bottom plate 50 is arranged at the bottom of the roller brush cavity.

[0092] In a possible implementation, the air suction passage 12 can be formed by an inner passage of a tubular structure arranged between the lower shell 15 and the upper cover 16.

[0093] In a possible implementation, referring to Figure 6 As shown, the floor brush structure further comprises a driving mechanism arranged in the housing 10, and the driving mechanism is configured to drive the roller brush 20 to rotate.

[0094] In a possible implementation, the driving mechanism comprises a motor.

[0095] In a possible implementation, referring to Figure 6 As shown, the floor brush structure further comprises a transmission mechanism 40, the transmission mechanism 40 comprises a driving wheel 41, a driven wheel 42 and a belt 43, the driving wheel 41 can be connected to the output shaft end of the motor, the driven wheel 42 is connected to the central shaft end of the roller brush 20, and the belt 43 is sleeved between the driving wheel 41 and the driven wheel 42; in operation, the motor drives the driving wheel 41 to rotate, the driving wheel 41 drives the driven wheel 42 to rotate through the belt 43, so as to transmit power to the roller brush 20 and realize the rotating movement of the roller brush 20.

[0096] The application further provides a cleaning device comprising the floor brush structure described above, and further comprising a motor component configured to provide suction.

[0097] The application further provides a cleaning device further comprising a dust collecting box configured to collect dust and sundries discharged from the air suction passage 12, so as to avoid secondary pollution.

[0098] Referring to Figure 1 and Figure 6 As shown, under the action of the motor component, air can enter the roller brush cavity from the dust suction port 13, then enter the air suction passage 12 through the rectification space 14, and finally enter the dust collecting box from the air suction passage 12; the dust and sundries in the dust collecting box are separated from the clean air, the clean air is finally discharged, and the dust and sundries are collected in the dust collecting box, which is convenient for the user to clean up.

[0099] In a possible implementation, the cleaning device provided by the application can be a dust collector, a sweeper, a mop, a washer, a robot with functions of sweeping and mopping, etc.

[0100] In operation, the rolling brush 20 rotates around its own rotation center line, when the rolling brush 20 moves to the surface to be cleaned, the stains on the surface to be cleaned are wiped off, at the same time, the dust and sundries on the surface to be cleaned are rolled and driven to the dust suction port 13 by the rolling brush 20, under the suction force in the air suction channel 12, the dust and sundries

[0101] The ground brush structure and the cleaning equipment provided by the utility model can remove the hair and sundries on the surface of the soft material to be cleaned and reduce the problem of hair winding on the surface of the rolling brush 20 under the premise of ensuring the power of the driving mechanism.

[0102] It should be noted that the numerical values and numerical ranges involved in the present application are approximate values, and there may be a certain range of error due to the manufacturing process, which can be considered negligible by those skilled in the art.
