Floor brush and dust collector

Abstract

The invention relates to the technical field of cleaning equipment, and provides a floor brush and a dust collector. The floor brush comprises a floor brush shell, a check block, an air valve and a driving piece. The dust collecting opening and the air inlet of the floor brush shell are both communicated with the interior of the floor brush shell. The driving piece can drive the check block to move so that the check block can at least partially open or close the dust collection opening. When the opening degree of the dust collecting opening is larger, large-particle dirt can be sucked into the floor brush shell through the dust collecting opening more easily. The driving piece can further drive the air valve to move so that the air valve can at least partially open or close the dust collection opening. When the opening degree of the air inlet is larger, the air outside the floor brush shell is more fully communicated with the interior of the floor brush shell, and the air pressure in the floor brush shell is larger, so that the floor brush moves more smoothly when passing through the long-wool carpet. The driving part can drive the stop block and the air valve to move respectively, and driving parts do not need to be arranged for the stop block and the air valve separately, so that the number of the driving parts of the floor brush is reduced, and the manufacturing cost of the floor brush is reduced.

Description

[0001] This disclosure claims the priority of a Chinese patent application filed with the Chinese Patent Office on January 27, 2025, with the application number 202510126171.7 and the application title "An Auto - regulating Vacuum Cleaner", the entire content of which is incorporated herein by reference. Technical Field

[0002] This disclosure relates to a floor brush and a vacuum cleaner, belonging to the technical field of cleaning equipment. Background Art

[0003] The dust collection port of a vacuum cleaner is used to suck in dirt, and the air inlet of the vacuum cleaner can be used for air intake to adjust the air pressure inside the cavity of the vacuum cleaner. When the vacuum cleaner needs to suck in large - particle dirt, the dust collection port of the vacuum cleaner can be opened to the maximum to facilitate the vacuum cleaner to suck in the large - particle dirt. When the vacuum cleaner is cleaning on a carpet, if the carpet has long pile, it will cause the motor of the vacuum cleaner to be overloaded and the resistance to increase. Therefore, it is necessary to open the air inlet to increase the air pressure inside the vacuum cleaner.

[0004] Currently, the opening and closing of the dust collection port and the air inlet of the vacuum cleaner are controlled manually by the user, and such an opening and closing method makes the use of the vacuum cleaner inconvenient. Summary of the Invention

[0063] In some embodiments, when the first convex post moves from one end of the first guiding groove section away from the first avoiding groove section to the connection of the first guiding groove section and the first avoiding groove section, the displacement of the transmission member in the first direction is a first distance, and the first distance is the same as the length of the second avoiding groove section. So that when the first convex post moves from one end of the first guiding groove section away from the first avoiding groove section to the connection of the first guiding groove section and the first avoiding groove section, the second convex post moves from one end of the second avoiding groove section away from the second guiding groove section to the connection of the second avoiding groove section and the second guiding groove section;

[0068] When one of the two drivers rotates to wind the corresponding pulling rope around the rotating shaft of the driver, the pulling rope pulls the transmission member to move along the first direction.

[0069] When the rotating shaft of the other driver among the two drivers rotates to wind the corresponding pulling rope around the rotating shaft of the driver, the pulling rope pulls the transmission member to move along the second direction.

The driving member can drive the stopper to move so that the stopper can at least partially open or close the dust collection port. When the opening degree of the dust collection port is larger, larger particulate dirt is more likely to be sucked into the floor brush housing through the dust collection port. The driving member can also drive the air valve to move so that the air valve can at least partially open or close the dust collection port. When the opening degree of the air inlet is larger, the atmosphere outside the floor brush housing is more fully in communication with the inside of the floor brush housing, and the air pressure inside the floor brush housing is larger, making the floor brush move more smoothly when passing over a shaggy carpet. The driving member can drive the stopper and the air valve to move respectively, and it is not necessary to separately provide driving components for the stopper and the air valve, so as to reduce the number of driving components of the floor brush of the present disclosure, thereby simplifying the structure of the floor brush and reducing the manufacturing cost of the floor brush.

[0076] The vacuum cleaner provided by the present disclosure includes the above floor brush, so that the structure of the vacuum cleaner can be simplified and the cost can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0099] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0100] The dust collection port of the vacuum cleaner is used to suck in dirt, and the air inlet of the vacuum cleaner can be used for air intake to adjust the air pressure inside the cavity of the vacuum cleaner. When the vacuum cleaner needs to suck in large - particle dirt, the dust collection port of the vacuum cleaner can be opened to the maximum to facilitate the vacuum cleaner to suck in the large - particle dirt. When the vacuum cleaner is cleaning on a carpet, if the carpet has long pile, it will cause the motor of the vacuum cleaner to be overloaded and the resistance to increase. Therefore, the air inlet needs to be opened to increase the air pressure inside the vacuum cleaner.

[0101] Currently, the dust collection port and the air intake port of the vacuum cleaner are opened and closed manually by the user, and such an opening and closing method makes the vacuum cleaner inconvenient to use.

[0102] In the floor brush proposed by the present disclosure, both the dust collection port and the air intake port of the floor brush housing communicate with the inside of the floor brush housing. The driving member can drive the stopper to move so that the stopper can at least partially open or close the dust collection port. When the opening degree of the dust collection port is larger, larger particulate dirt is more likely to be sucked into the floor brush housing through the dust collection port. The driving member can also drive the valve to move so that the valve can at least partially open or close the air intake port. When the opening degree of the air intake port is larger, the atmosphere outside the floor brush housing communicates more fully with the inside of the floor brush housing, and the air pressure inside the floor brush housing is larger, making the floor brush move more smoothly when passing over a shag carpet. The driving member can drive the stopper and the valve to move respectively, and it is not necessary to separately provide driving components for the stopper and the valve, so as to reduce the number of driving components of the floor brush of the present disclosure, thereby simplifying the structure of the floor brush and reducing the manufacturing cost of the floor brush.

[0103] The vacuum cleaner proposed by the present disclosure includes the above-mentioned floor brush, so that the structure of the vacuum cleaner can be simplified and the cost can be reduced.

[0104] The following will describe the content of the present disclosure in detail with reference to the drawings, so that those skilled in the art can understand the content of the present disclosure more clearly and in detail.

[0105] The present disclosure proposes a floor brush, referring to Figures 1 to 4 as shown, including a floor brush housing 100, a driving member 200, a stopper 300 and a valve 400. This floor brush can be applied to a vacuum cleaner.

[0106] Among them, the floor brush housing 100 is the basic component of the floor brush of the present disclosure. The floor brush housing 100 can provide an installation basis for at least some other components of the floor brush and serve the purpose of protecting at least some other components. The floor brush housing 100 can be made of a metal material, so that the floor brush housing 100 has better structural strength, thereby making the durability and reliability of the floor brush housing 100 better. Of course, the floor brush housing 100 can also be made of a polymer material, so that the floor brush housing 100 has a certain structural strength while being relatively light in weight.

[0107] Referring to Figures 2 to 3 as shown, the floor brush housing 100 has a dust collection port 120. The dust collection port 120 is an opening on the surface of the floor brush housing 100, and the dust collection port 120 communicates with the inside of the floor brush housing 100. Specifically, the floor brush housing 100 has a cavity 110, and the dust collection port 120 communicates with the cavity 110. When the floor brush of the present disclosure is applied to a vacuum cleaner, the fan component of the vacuum cleaner can form a negative pressure in the cavity 110, so that external dirt can be sucked into the cavity 110 of the housing through the dust collection port 120.

[0108] Reference Figure 3 As shown, the floor brush housing 100 further has an air inlet 130. The air inlet 130 is an opening on the surface of the floor brush housing 100, and the air inlet 130 communicates with the inside of the floor brush housing 100. Specifically, the air inlet 130 communicates with the cavity 110. Air in the atmosphere outside the floor brush housing 100 can enter the cavity 110 through the air inlet 130 to increase the air pressure in the cavity 110, thereby changing the vacuum degree inside the floor brush housing 100.

[0109] Reference Figure 4 As shown, the stopper 300 is connected to at least one of the floor brush housing 100 and the driving member 200. The driving member 200 is configured to drive the stopper 300 to move so that the stopper 300 at least partially opens or at least partially closes the dust collection port 120. Specifically, by driving the stopper 300 to move by the driving member 200, the opening and closing degree of the dust collection port 120 can be correspondingly adjusted. When the opening degree of the dust collection port 120 is larger, the size of the dirt passing through the dust collection port 120 can be correspondingly larger. Therefore, when the floor brush of the present disclosure needs to clean large dirt, the driving member 200 can be used to drive the stopper 300 to move so that the dust collection port 120 is partially opened or fully opened.

[0110] When the opening degree of the dust collection port 120 is smaller, the size of the dirt passing through the dust collection port 120 can be correspondingly smaller. Therefore, when the floor brush of the present disclosure needs to clean small particle dirt, the driving member 200 can be used to drive the stopper 300 to move so that the dust collection port 120 is partially closed or fully closed. By reducing the opening size of the dust collection port 120 with the stopper 300, the sealing performance inside the floor brush housing 100 can be improved, thereby increasing the vacuum degree inside the floor brush housing 100 so that the dirt is more easily sucked into the floor brush housing 100.

[0111] By driving the stopper 300 to move by the driving member 200, the user does not have to manually push the stopper 300 to move, which makes the adjustment of the opening and closing degree of the dust collection port 120 more convenient, thereby making the floor brush and the vacuum cleaner of the present disclosure more convenient to use.

[0112] Reference Figure 4As shown, the air valve 400 is connected to at least one of the floor brush housing 100 and the driving member 200. The driving member 200 is configured to drive the air valve 400 to move so that the air valve 400 at least partially opens or at least partially closes the air inlet 130. Specifically, by driving the air valve 400 to move by the driving member 200, the opening and closing degree of the air inlet 130 can be correspondingly adjusted. When the opening degree of the air inlet 130 is larger, the amount of gas entering the interior of the floor brush housing 100 through the air inlet 130 is larger, making the air pressure inside the floor brush housing 100 larger and the vacuum degree lower. Therefore, when the floor brush of the present disclosure needs to clean a shag carpet, the driving member 200 can be used to drive the air valve 400 to move so that the air inlet 130 is partially opened or fully opened, so that the floor brush of the present disclosure can move smoothly on the shag carpet and the load on the fan component can be reduced.

[0113] When the opening degree of the air inlet 130 is smaller, the amount of gas entering the interior of the floor brush housing 100 through the air inlet 130 is smaller, making the air pressure inside the floor brush housing 100 smaller and the vacuum degree higher. Therefore, when the floor brush of the present disclosure needs to clean dirt more thoroughly, the driving member 200 can be used to drive the air valve 400 to move so that the air inlet 130 is partially closed or fully closed. By reducing the opening degree of the air inlet 130 through the air valve 400, the sealing performance inside the floor brush housing 100 can be improved, thereby increasing the vacuum degree inside the floor brush housing 100 so that dirt is more easily sucked into the floor brush housing 100.

[0114] By driving the air valve 400 to move by the driving member 200, the user does not have to manually push the air valve 400 to move, which makes the adjustment of the opening and closing degree of the air inlet 130 more convenient, and thus makes the floor brush and the vacuum cleaner of the present disclosure more convenient to use.

[0115] Since the driving member 200 can drive the stopper 300 and the air valve 400 to move respectively, it is not necessary to separately provide a plurality of driving components for driving the stopper 300 and the air valve 400 respectively, so as to reduce the number of driving components of the floor brush of the present disclosure, thereby simplifying the structure of the floor brush and reducing the manufacturing cost of the floor brush.

[0116] In some embodiments, refer to Figures 4 to 5As shown, in order for the driving member 200 to drive the stopper 300 and the valve 400 to move, the floor brush of the present disclosure may further be provided with a transmission member 500. The transmission member 500 is connected to the driving member 200, and the driving member 200 is configured to drive the transmission member 500 to move, so that the transmission member 500 pushes the stopper 300 to move to at least partially open or at least partially close the dust collection port 120. The transmission member 500 can transmit the power output by the driving member 200 to the stopper 300, so that the stopper 300 moves. When the distance between the driving member 200 and the stopper 300 is large, by providing the transmission member 500, it is convenient for the power output by the driving member 200 to act on the stopper 300. In this way, the limitation of the distance between the driving member 200 and the stopper 300 is smaller, which is beneficial to the internal structure design of the floor brush.

[0117] In some embodiments, referring to Figure 1 and Figure 6 shown, the stopper 300 is movably connected to the floor brush housing 100, so that the stopper 300 can move relative to the floor brush housing 100. In this way, the floor brush housing 100 can support the stopper 300, making the stopper 300 more stable during the movement. The driving member 200 is configured to drive the transmission member 500 to move in a first direction, so that the transmission member 500 pushes the stopper 300 to move to at least partially open the dust collection port 120. Wherein, the first direction is parallel to the Figure 1 and Figure 6 X direction in. Specifically, by adjusting the distance of the displacement of the driving member 200 driving the transmission member 500 in the first direction, the distance that the transmission member 500 pushes the stopper 300 to move can be correspondingly adjusted, so as to adjust the degree to which the stopper 300 opens the dust collection port 120. The greater the distance that the transmission member 500 pushes the stopper 300 to move in the first direction, the greater the degree to which the stopper 300 opens the dust collection port 120.

[0118] The driving member 200 is further configured to drive the transmission member 500 to move in a second direction, so that the transmission member 500 pushes the stopper 300 to move to at least partially close the dust collection port 120. Specifically, by adjusting the distance of the displacement of the driving member 200 driving the transmission member 500 in the second direction, the distance that the transmission member 500 pushes the stopper 300 to move can be correspondingly adjusted, so as to adjust the degree to which the stopper 300 closes the dust collection port 120. The greater the distance that the transmission member 500 pushes the stopper 300 to move in the second direction, the greater the degree to which the stopper 300 closes the dust collection port 120.

[0119] The first direction and the second direction are opposite to each other. In this way, after the transmission member 500 moves along the first direction to push the stopper 300 to fully open the dust collection port 120, the transmission member 500 can move along the second direction to push the stopper 300 to fully close the dust collection port 120. In this way, when the stopper 300 is converted between fully opening and fully closing the dust collection port 120, the displacement range of the transmission member 500 is relatively smaller, so that the structure of the floor brush of the present disclosure can be more compact.

[0120] In some embodiments, referring to Figure 6 as shown, the stopper 300 of the present disclosure can be driven to move along the third direction or the fourth direction. The third direction and the fourth direction are opposite to each other, and the third direction is arranged at an angle with the first direction. Correspondingly, the third direction and the second direction, and the second direction and the fourth direction are both arranged at an angle. Both the third direction and the fourth direction are parallel to the Figure 6 Y direction in

[0121] When the transmission member 500 moves along the first direction, the transmission member 500 abuts against the stopper 300 and drives the stopper 300 to move along the third direction, so that the stopper 300 at least partially opens the dust collection port 120. In this way, the stopper 300 can at least partially open the dust collection port 120 without having to move along with the transmission member 500 relative to the floor brush housing 100 in the first direction.

[0122] When the transmission member 500 moves along the second direction, the transmission member 500 abuts against the stopper 300 and drives the stopper 300 to move along the fourth direction, so that the stopper 300 at least partially closes the dust collection port 120. In this way, the stopper 300 can at least partially close the dust collection port 120 without having to move along with the transmission member 500 relative to the floor brush housing 100 in the second direction.

[0123] The first direction can be set to be parallel to the width direction of the floor brush housing 100. Correspondingly, the second direction is also parallel to the width direction of the floor brush housing 100. The third direction can be set to be parallel to the height direction of the floor brush housing 100. Correspondingly, the fourth direction is also parallel to the height direction of the floor brush housing 100.

[0124] Among them, the dust collection port 120 can be a long strip-shaped opening. The width direction of the dust collection port 120 can be the width direction of the floor brush housing 100, and the dust collection port 120 is located on the front surface of the floor brush housing 100. The ratio of the width to the height of the dust collection port 120 is relatively large, so that the dust collection port 120 is an elongated structure. In this way, when the floor brush moves on the ground, the dirt on the front surface of the floor brush housing 100 can be sucked into the floor brush housing 100 through the dust collection port 120. In addition, it should also be understood that the larger the size of the dust collection port 120 in the width direction of the floor brush housing 100, the larger the width of the corresponding ground of the dust collection port 120, and the higher the efficiency of sucking the dirt into the floor brush housing 100 through the dust collection port 120. The height dimension of the dust collection port 120 in the height direction of the floor brush housing 100 is relatively small, which can make the dust collection port 120 adapt to the height of the floor brush housing 100.

[0125] It should be understood that if the stopper 300 moves along the first direction or the second direction with the transmission member 500 to at least partially open or close the dust collection port 120, correspondingly, the larger the width dimension of the dust collection port 120 in the first direction, the greater the displacement required for the stopper 300 to completely open or close the dust collection port 120 in the first direction. When the stopper 300 completely opens the dust collection port 120, the width dimension of the floor brush housing 100 in the first direction is at least not less than twice the width dimension of the dust collection port 120 in the first direction, which will cause the width of the floor brush housing 100 in the first direction to be too wide, and then cause the structure of the floor brush housing 100 to be not compact.

[0126] In the present disclosure, the transmission member 500 pushes the stopper 300 to move along the third direction or the fourth direction to at least partially open or close the dust collection port 120, so that the stopper 300 can move along the height direction of the floor brush housing 100. Correspondingly, the dust collection port 120 can be opened or closed when the stopper 300 moves a relatively small distance in the third direction or the fourth direction. In addition, the displacement of the transmission member 500 in the first direction and the second direction can also be relatively shorter, so that the structure of the floor brush of the present disclosure is more compact.

[0127] In some embodiments, referring to Figure 7 As shown, in order to enable the transmission member 500 to move along the first direction to drive the stopper 300 to move along the third direction, the transmission member 500 can be provided with a first guiding surface 511a. The first guiding surface 511a is arranged at an angle with both the first direction and the third direction, so that the first guiding surface 511a is an inclined surface relative to both the width direction and the height direction of the floor brush housing 100.

[0128] When the transmission member 500 moves in the first direction, a part of the stopper 300 contacts the first guiding surface 511a, and the stopper 300 slides along the first guiding surface 511a, so that the transmission member 500 lifts the stopper 300 to move in the third direction. Specifically, when the transmission member 500 moves in the first direction, the first guiding surface 511a can convert a part of the acting force of the transmission member 500 in the first direction into the acting force for lifting the stopper 300 to move in the third direction, so that the stopper 300 moves in the third direction.

[0129] In some embodiments, referring to Figure 7 As shown, in order to enable the transmission member 500 to move in the second direction to drive the stopper 300 to move in the fourth direction, the transmission member 500 may be provided with a second guiding surface 511b. The second guiding surface 511b is arranged at an angle with both the second direction and the fourth direction, so that the second guiding surface 511b is an inclined surface relative to both the width direction and the height direction of the brush housing 100.

[0130] When the transmission member 500 moves in the second direction, a part of the stopper 300 contacts the second guiding surface 511b, and the stopper 300 slides along the second guiding surface 511b, so that the transmission member 500 presses the stopper 300 to move in the fourth direction. Specifically, when the transmission member 500 moves in the second direction, the second guiding surface 511b can convert a part of the acting force of the transmission member 500 in the second direction into the acting force for pressing the stopper 300 to move in the fourth direction, so that the stopper 300 moves in the fourth direction.

[0131] In some embodiments, it should be understood that when the stopper 300 moves along the first guiding surface 511a, the magnitude of the displacement of the stopper 300 in the third direction is affected by the length of the first guiding surface 511a and the magnitudes of the angles between the first guiding surface 511a and the first direction and the third direction. The longer the length of the first guiding surface 511a and the larger the angle between it and the first direction, correspondingly, the greater the displacement of the stopper 300 in the third direction after moving along the first guiding surface 511a. The shorter the length of the first guiding surface 511a and the smaller the angle between it and the first direction, correspondingly, the smaller the displacement of the stopper 300 in the third direction after moving along the first guiding surface 511a.

[0132] When the stopper 300 moves along the second guiding surface 511b, the magnitude of the displacement of the stopper 300 in the fourth direction is affected by the length of the second guiding surface 511b and the magnitudes of the angles between the second guiding surface 511b and the second direction and the fourth direction. The longer the length of the second guiding surface 511b and the larger the angle between it and the second direction, correspondingly, the greater the displacement of the stopper 300 in the fourth direction after moving along the second guiding surface 511b. The shorter the length of the second guiding surface 511b and the smaller the angle between it and the second direction, correspondingly, the smaller the displacement of the stopper 300 in the fourth direction after moving along the second guiding surface 511b.

[0133] Reference Figure 7 As shown, in the present disclosure, the first guiding surface 511a and the second guiding surface 511b have the same length and are parallel. This can make the distances that the stopper 300 can move in the third direction and the fourth direction the same. Correspondingly, after the stopper 300 moves a certain distance in the third direction to fully open the dust collection port 120, it can move the same distance in the fourth direction to fully close the dust collection port 120, so that the distance that the stopper 300 moves in the height direction of the floor brush housing 100 is relatively the shortest, making the floor brush structure of the present disclosure more compact.

[0134] In some embodiments, reference Figures 6 to 7 As shown, the transmission member 500 of the present disclosure may further be provided with a first guiding groove 510. Both the first guiding surface 511a and the second guiding surface 511b are inner walls of the first guiding groove 510, and the first guiding surface 511a and the second guiding surface 511b are oppositely arranged.

[0135] Specifically, the first guiding groove 510 may be arranged at an angle with respect to the first direction and the third direction, and a part of the stopper 300 may be located in the first guiding groove 510. The first guiding groove 510 can serve the purpose of limiting the stopper 300, so that the stopper 300 can remain stable when moving in the third direction and the fourth direction.

[0136] In some embodiments, reference Figure 6 As shown, in order to enable a part of the stopper 300 to be arranged in the first guiding groove 510, the stopper 300 may be provided with a first convex post 310. The first convex post 310 is movably embedded in the first guiding groove 510, so that the first convex post 310 can reciprocate along the extending direction of the first guiding groove 510. At least one of the opposite sides of the first convex post 310 contacts at least one of the first guiding surface 511a and the second guiding surface 511b, so as to ensure that the first convex post 310 can slide along the first guiding surface 511a and the second guiding surface 511b.

[0137] Specifically, the vertical distance between the first guiding surface 511a and the second guiding surface 511b may be set to match the outer diameter of the first convex post 310, so that the opposite sides of the first convex post 310 can respectively contact the first guiding surface 511a and the second guiding surface 511b. In this way, when the first convex post 310 moves along the first guiding groove 510, its opposite sides can always remain in contact with the first guiding surface 511a and the second guiding surface 511b. The first guiding surface 511a and the second guiding surface 511b serve the purpose of limiting the first convex post 310, so that the first convex post 310 can only move along the extending direction of the first guiding groove 510, thereby avoiding skew when the stopper 300 moves.

[0138] In some embodiments, referenceFigure 7 As shown, the first guiding groove 510 of the present disclosure may be provided to include a first guiding groove section 511 and a first avoiding groove section 512. One end of the first avoiding groove section 512 is connected to the first guiding groove section 511, and the first avoiding groove section 512 is arranged along the first direction. A first guiding surface 511a and a second guiding surface 511b are located in the first guiding groove section 511. The first convex post 310 can move from the first guiding groove section 511 to the first avoiding groove section 512, and can also move from the first avoiding groove section 512 to the first guiding groove section 511. When the first convex post 310 moves relative to the transmission member 500 within the first guiding groove section 511, the first convex post 310 can move in the third direction or the fourth direction, so that the stopper 300 can open or close the dust collection port 120. When the first convex post 310 moves relative to the transmission member 500 within the first avoiding groove section 512, the first convex post 310 does not move in the third direction or the fourth direction, that is, the height of the stopper 300 does not change, and the degree to which the stopper 300 opens or closes the dust collection port 120 does not change either.

[0139] Specifically, when the first convex post 310 abuts against the end of the first guiding groove section 511 away from the first avoiding groove section 512, the stopper 300 closes the dust collection port 120 to the first maximum closing degree, and at this time, the stopper 300 completely closes the dust collection port 120.

[0140] When the first convex post 310 is located at the connection between the first guiding groove section 511 and the first avoiding groove section 512, the stopper 300 opens the dust collection port 120 to the first maximum opening degree, and at this time, the stopper 300 completely opens the dust collection port 120.

[0141] When the first convex post 310 is located within the first avoiding groove section 512 and the transmission member 500 moves along the first direction or the second direction, the first convex post 310 moves relative to the transmission member 500 along the first avoiding groove section 512, and the stopper 300 remains in the state of opening the dust collection port 120 to the first maximum opening degree. At this time, no matter whether the transmission member 500 moves along the first direction or the second direction, the state in which the stopper 300 opens the dust collection port 120 to the first maximum opening degree will not change.

[0142] Therefore, the transmission member 500 can move a relatively greater distance in the first direction and the second direction, and it will not affect the stopper 300 from opening the dust collection port 120 to the first maximum opening degree. Correspondingly, the transmission member 500 can also move freely without driving the stopper 300 to move to drive other components.

[0143] In some embodiments, referring to Figure 8 As shown, the valve 400 in the present disclosure can be connected to the transmission member 500. Correspondingly, when the transmission member 500 moves along the first direction or the second direction, the valve 400 also moves along the first direction or the second direction accordingly.

[0144] When the transmission member 500 moves in the first direction, the transmission member 500 drives the valve 400 to move in the first direction until the intake port 130 is at least partially opened. Specifically, during the process that the transmission member 500 drives the valve 400 to move in the first direction, the valve 400 gradually opens the intake port 130 until the valve 400 fully opens the intake port 130.

[0145] When the transmission member 500 moves in the second direction, the transmission member 500 drives the valve 400 to move in the second direction until the intake port 130 is at least partially closed. Specifically, during the process that the transmission member 500 drives the valve 400 to move in the second direction, the valve 400 gradually closes the intake port 130 until the valve 400 fully closes the intake port 130.

[0146] In some embodiments, as shown in Figure 8 When the inner wall of the first guiding groove section 511 away from the first avoiding groove section 512 of the transmission member 500 abuts against the first convex column 310, the valve 400 closes the intake port 130 to the second maximum closing degree. Specifically, when the dust collecting port 120 is closed to the first maximum closing degree by the stopper 300, the valve 400 closes the intake port 130 to the second maximum closing degree, and at this time both the intake port 130 and the dust collecting port 120 are closed.

[0147] When the inner wall of the first avoiding groove section 512 away from the first guiding groove section 511 of the transmission member 500 abuts against the first convex column 310, the valve 400 opens the intake port 130 to the second maximum opening degree. Specifically, when the dust collecting port 120 is opened to the first maximum opening degree by the stopper 300, the valve 400 opens the intake port 130 to the second maximum opening degree, and at this time both the intake port 130 and the dust collecting port 120 are fully opened.

[0148] Thus, the dust collecting port 120 and the intake port 130 can be opened or closed simultaneously. In addition, since the maximum displacement distances of the transmission member 500 in the first direction and the second direction are the length of the first guiding groove section 511 in the first direction plus the length of the first avoiding groove section 512, the maximum displacement distances of the transmission member 500 in the first direction and the second direction can be made larger. Correspondingly, the maximum displacement distances of the valve 400 in the first direction and the second direction are also larger, and the size of the intake port 130 in the first direction is also larger, so that the size of the intake port 130 is larger. In this way, when the valve 400 opens the intake port 130 to the second maximum opening degree, the amount of gas delivered into the floor brush housing 100 through the intake port 130 is larger, and the vacuum degree in the floor brush housing 100 can be adjusted to be lower, thereby increasing the vacuum degree range in the floor brush housing 100, and finally enabling the floor brush of the present disclosure to adapt to more working conditions.

[0149] In addition, in other embodiments, it is also possible to set that when the transmission member 500 moves in the first direction and the first convex column 310 moves from the connection between the first guiding groove section 511 and the first avoidance groove section 512 into the first avoidance groove, the valve 400 starts to gradually open the air inlet 130, and when the inner wall of the first avoidance groove section 512 away from the first guiding groove section 511 abuts against the first convex column 310, the valve 400 opens the air inlet 130 to the second maximum opening degree. This can ensure that when the baffle 300 gradually opens the dust collection port 120, the valve 400 has not yet opened the air inlet 130. When the baffle 300 opens the dust collection port 120 to the first maximum opening degree, the valve 400 starts to open the air inlet 130, so that the dust collection port 120 and the air inlet 130 can be opened successively and can ultimately maintain the open and closed states simultaneously.

[0150] In some embodiments, referring to Figures 6 to 7 As shown, in order to enable the transmission member 500 to drive the valve 400 to move to at least partially open or at least partially close the air inlet 130 when the transmission member 500 moves in the first direction and the second direction. In addition to the above-mentioned direct connection method between the valve 400 and the transmission member 500, the valve 400 can also be movably connected to the floor brush housing 100, so that the valve 400 can move relative to the floor brush housing 100. In this way, the floor brush can play a role in supporting the valve 400, making the valve 400 more stable during the movement. The driving member 200 is configured to drive the transmission member 500 to move in the first direction, so that the transmission member 500 pushes the valve 400 to move to at least partially open the air inlet 130. Specifically, by adjusting the distance of the displacement of the driving member 200 driving the transmission member 500 in the first direction, the distance that the transmission member 500 pushes the valve 400 to move can be correspondingly adjusted, thereby adjusting the degree to which the valve 400 opens the air inlet 130. The greater the distance that the transmission member 500 pushes the valve 400 to move in the first direction, the greater the degree to which the valve 400 opens the air inlet 130.

[0151] The driving member 200 is further configured to drive the transmission member 500 to move in the second direction, so that the transmission member 500 pushes the valve 400 to move to at least partially close the air inlet 130. Specifically, by adjusting the distance of the displacement of the driving member 200 driving the transmission member 500 in the second direction, the distance that the transmission member 500 pushes the valve 400 to move can be correspondingly adjusted, thereby adjusting the degree to which the valve 400 closes the air inlet 130. The greater the distance that the transmission member 500 pushes the valve 400 to move in the second direction, the greater the degree to which the valve 400 closes the air inlet 130.

[0152] In some embodiments, referring to Figures 6 to 7As shown, the valve 400 of the present disclosure can be driven to move in a fifth direction or a sixth direction, the fifth direction and the sixth direction are opposite to each other, and the fifth direction is arranged at an angle with the first direction. Correspondingly, the fifth direction and the second direction, and the second direction and the sixth direction are both arranged at an angle. Both the fifth direction and the sixth direction are parallel to Figure 6 the Y direction in

[0153] When the transmission member 500 moves in the first direction, the transmission member 500 abuts against the valve 400 and drives the valve 400 to move in the fifth direction, so that the valve 400 at least partially opens the air inlet 130. In this way, the valve 400 can at least partially open the air inlet 130 without having to move along the first direction with the transmission member 500.

[0154] When the transmission member 500 moves in the second direction, the transmission member 500 abuts against the valve 400 and drives the valve 400 to move in the sixth direction, so that the valve 400 at least partially closes the air inlet 130. In this way, the valve 400 can at least partially close the air inlet 130 without having to move along the second direction with the transmission member 500.

[0155] The fifth direction can be set to be parallel to the height direction of the floor brush housing 100. Correspondingly, the sixth direction is also parallel to the height direction of the floor brush housing 100.

[0156] Wherein, the air inlet 130 can be a strip-shaped opening, the width direction of the air inlet 130 can be the width direction of the floor brush housing 100, and the air inlet 130 is located above the dust collection port 120. The ratio of the width to the height of the air inlet 130 is relatively large, so that the air inlet 130 is an elongated structure. It should be understood that the larger the dimension of the air inlet 130 along the width direction of the floor brush housing 100, the greater the amount of gas that can enter the floor brush housing 100 through the air inlet 130, and the lower the vacuum degree in the floor brush housing 100 can be adjusted accordingly. The height dimension of the air inlet 130 in the height direction of the floor brush housing 100 is relatively small, which can make the air inlet 130 adapt to the structure of the floor brush housing 100.

[0157] It should be understood that if the valve 400 moves along the first direction or the second direction with the transmission member 500 to at least partially open or close the air inlet 130, correspondingly, the larger the width dimension of the air inlet 130 in the first direction, the greater the displacement required for the valve 400 to fully open or close the air inlet 130 in the first direction. When the valve 400 fully opens the air inlet 130, the width dimension of the floor brush housing 100 in the first direction is at least not less than twice the width dimension of the air inlet 130 in the first direction, which will cause the width of the floor brush housing 100 in the first direction to be too large, and thus the structure of the floor brush housing 100 is not compact.

[0158] In the present disclosure, the transmission member 500 pushes the valve 400 to move in the fifth direction or the sixth direction to at least partially open or close the air inlet 130, so that the valve 400 can move along the height direction of the floor brush housing 100. Correspondingly, when the valve 400 moves a relatively small distance in the fifth direction or the sixth direction, the air inlet 130 can be opened or closed. In addition, the displacements of the transmission member 500 in the first direction and the second direction can also be relatively shorter, so that the structure of the floor brush of the present disclosure is more compact.

[0159] In some embodiments, referring to Figure 7 As shown, in order to enable the transmission member 500 to move in the first direction to drive the valve 400 to move in the fifth direction, the transmission member 500 may be provided with a third guiding surface 521a. The third guiding surface 521a is disposed at an angle with both the first direction and the fifth direction, so that the third guiding surface 521a is an inclined surface relative to both the width direction and the height direction of the floor brush housing 100.

[0160] When the transmission member 500 moves in the first direction, a part of the valve 400 contacts the third guiding surface 521a, and the valve 400 slides along the third guiding surface 521a, so that the transmission member 500 presses the valve 400 to move in the fifth direction. Specifically, when the transmission member 500 moves in the first direction, the third guiding surface 521a can convert a part of the acting force of the transmission member 500 in the first direction into an acting force for lifting the valve 400 to move in the fifth direction, so that the valve 400 moves in the fifth direction.

[0161] In some embodiments, referring to Figure 7 As shown, in order to enable the transmission member 500 to move in the second direction to drive the valve 400 to move in the sixth direction, the transmission member 500 may be provided with a fourth guiding surface 521b. The fourth guiding surface 521b is disposed at an angle with both the second direction and the sixth direction, so that the fourth guiding surface 521b is an inclined surface relative to both the width direction and the height direction of the floor brush housing 100.

[0162] When the transmission member 500 moves in the second direction, a part of the valve 400 contacts the fourth guiding surface 521b, and the valve 400 slides along the fourth guiding surface 521b, so that the transmission member 500 lifts the valve 400 to move in the sixth direction. Specifically, when the transmission member 500 moves in the second direction, the fourth guiding surface 521b can convert a part of the acting force of the transmission member 500 in the second direction into an acting force for pressing the valve 400 to move in the sixth direction, so that the valve 400 moves in the sixth direction.

[0163] Of course, it is also possible to arrange the transmission member 500 to lift the valve 400 to move in the fifth direction and press the valve 400 to move in the sixth direction, and the present disclosure does not limit this.

[0164] In some embodiments, it should be understood that when the valve 400 moves along the third guiding surface 521a, the magnitude of the displacement of the valve 400 in the fifth direction is affected by the length of the third guiding surface 521a and the magnitudes of the angles between the third guiding surface 521a and the first direction and the fifth direction. The longer the length of the third guiding surface 521a and the larger the angle with the first direction, correspondingly, the greater the displacement of the valve 400 in the fifth direction after moving along the third guiding surface 521a. The shorter the length of the third guiding surface 521a and the smaller the angle with the first direction, correspondingly, the smaller the displacement of the valve 400 in the fifth direction after moving along the third guiding surface 521a.

[0165] When the valve 400 moves along the fourth guiding surface 521b, the magnitude of the displacement of the valve 400 in the sixth direction is affected by the length of the fourth guiding surface 521b and the magnitudes of the angles between the fourth guiding surface 521b and the second direction and the sixth direction. The longer the length of the fourth guiding surface 521b and the larger the angle with the second direction, correspondingly, the greater the displacement of the valve 400 in the sixth direction after moving along the fourth guiding surface 521b. The shorter the length of the fourth guiding surface 521b and the smaller the angle with the second direction, correspondingly, the smaller the displacement of the valve 400 in the sixth direction after moving along the fourth guiding surface 521b.

[0166] In the present disclosure, with reference to Figure 7 As shown, the third guiding surface 521a and the fourth guiding surface 521b have the same length and are parallel. This can make the distances that the valve 400 can move in the fifth direction and the sixth direction the same. Correspondingly, after the valve 400 moves a certain distance in the fifth direction to fully open the air inlet 130, moving the same distance in the sixth direction can fully close the air inlet 130, so that the distance that the valve 400 moves in the height direction of the floor brush housing 100 is relatively the shortest, making the floor brush structure of the present disclosure more compact.

[0167] In some embodiments, the transmission member 500 of the present disclosure may also be provided with a second guiding groove 520. Both the third guiding surface 521a and the fourth guiding surface 521b are inner walls of the second guiding groove 520, and the third guiding surface 521a and the fourth guiding surface 521b are opposite and parallel to each other.

[0168] Specifically, the second guiding groove 520 may be arranged at an angle with respect to the first direction and the fifth direction, and a part of the valve 400 may be located within the second guiding groove 520. The second guiding groove 520 can serve the purpose of limiting the valve 400, so that the valve 400 can remain stable when moving in the fifth direction and the sixth direction.

[0169] In some embodiments, with reference to Figure 9As shown, in order to enable a part of the valve 400 to be disposed in the second guiding groove 520, the valve 400 may be provided with a second stud 410. The second stud 410 is movably embedded in the second guiding groove 520, so that the second stud 410 can reciprocate along the extending direction of the second guiding groove 520. At least one of the opposite sides of the second stud 410 contacts at least one of the third guiding surface 521a and the fourth guiding surface 521b, so as to ensure that the second stud 410 can slide along the third guiding surface 521a and the fourth guiding surface 521b.

[0170] Specifically, the vertical distance between the third guiding surface 521a and the fourth guiding surface 521b may be set to match the outer diameter of the second stud 410, so that the opposite sides of the second stud 410 can respectively contact the third guiding surface 521a and the fourth guiding surface 521b. In this way, when the second stud 410 moves along the second guiding groove 520, its opposite sides can always remain in contact with the third guiding surface 521a and the fourth guiding surface 521b. The third guiding surface 521a and the fourth guiding surface 521b serve the purpose of limiting the second stud 410, so that the second stud 410 can only move along the extending direction of the second guiding groove 520, thereby avoiding deflection when the valve 400 moves.

[0171] In some embodiments, referring to Figure 7 As shown, the second guiding groove 520 of the present disclosure may be provided with a second guiding groove section 521 and a second avoiding groove section 522. One end of the second avoiding groove section 522 is communicated with the second guiding groove section 521, and the second avoiding groove section 522 is arranged along the first direction. The third guiding surface 521a and the fourth guiding surface 521b are located in the second guiding groove section 521. The second stud 410 can move from the second guiding groove section 521 to the second avoiding groove section 522, and can also move from the second avoiding groove section 522 to the second guiding groove section 521. When the second stud 410 moves relative to the transmission member 500 in the second guiding groove section 521, the second stud 410 can move in the fifth direction or the sixth direction, so that the valve 400 can open or close the air inlet 130. When the second stud 410 moves relative to the transmission member 500 in the second avoiding groove section 522, the second stud 410 does not move in the fifth direction or the sixth direction, that is, the height of the valve 400 does not change, and the degree of opening or closing of the air inlet 130 by the valve 400 does not change.

[0172] Specifically, when the second stud 410 abuts against the end of the second guiding groove section 521 away from the second avoiding groove section 522, the valve 400 opens the air inlet 130 to the second maximum opening degree, and at this time the valve 400 fully opens the air inlet 130.

[0173] When the second convex post 410 is located at the connection of the second guiding groove section 521 and the second avoiding groove section 522, the valve 400 closes the air inlet 130 to the second maximum closing degree, and at this time, the valve 400 completely closes the air inlet 130.

[0174] When the second convex post 410 is located within the second avoiding groove section 522 and the transmission member 500 moves in the first direction or the second direction, the second convex post 410 moves relative to the transmission member 500 along the second avoiding groove section 522, and the valve 400 remains in the state of closing the air inlet 130 to the second maximum closing degree. At this time, regardless of whether the transmission member 500 moves in the first direction or the second direction, the state of the valve 400 closing the air inlet 130 to the second maximum closing degree will not change.

[0175] In some embodiments, referring to Figure 7 As shown, when the first convex post 310 moves from the end of the first guiding groove section 511 away from the first avoiding groove section 512 to the connection of the first guiding groove section 511 and the first avoiding groove section 512, the displacement of the transmission member 500 in the first direction is a first distance, and the first distance is the same as the length of the second avoiding groove section 522. In this way, when the first convex post 310 moves from the end of the first guiding groove section 511 away from the first avoiding groove section 512 to the connection of the first guiding groove section 511 and the first avoiding groove section 512, the second convex post 410 moves from the end of the second avoiding groove section 522 away from the second guiding groove section 521 to the connection of the second avoiding groove section 522 and the first guiding groove section 511.

[0176] Thus, after the baffle 300 opens the dust collection port 120 to the first maximum opening degree and the transmission member 500 continues to move in the first direction, the valve 400 begins to gradually open the air inlet 130 until the valve 400 opens the air inlet 130 to the second maximum opening degree, so that the dust collection port 120 and the air inlet 130 can be opened successively.

[0177] When the second convex post 410 moves from the end where the second guiding groove section 521 is connected to the second avoiding groove section 522 to the end of the second guiding groove section 521 away from the second avoiding groove section 522, the displacement of the transmission member 500 in the first direction is a second distance, and the second distance is the same as the length of the second avoiding groove section 522, so that when the second convex post 410 moves from the end where the second guiding groove section 521 is connected to the second avoiding groove section 522 to the end of the second guiding groove section 521 away from the second avoiding groove section 522, the first convex post 310 moves from the end where the first avoiding groove section 512 is connected to the first guiding groove section 511 to the end of the first avoiding groove section 512 away from the first guiding groove section 511.

[0178] Thus, when the valve 400 opens the air inlet 130 to the second maximum opening degree, the stopper 300 can remain in the state of opening the dust collection port 120 to the first maximum opening degree. Correspondingly, the floor brush of the present disclosure has a state in which the dust collection port 120 is open and the air inlet 130 is closed, and a state in which the dust collection port 120 and the air inlet 130 are opened simultaneously.

[0179] In some embodiments, referring to Figures 6 to 7 As shown, the first avoidance groove section 512 of the present disclosure can be connected to the top side of the first guiding groove section 511, and the second avoidance groove section 522 can be connected to the top side of the second guiding groove section 521.

[0180] In some embodiments, referring to Figures 6 to 7 As shown, the number of the first guiding groove 510 and the second guiding groove 520 of the present disclosure can be set to one or more. Correspondingly, the number of the first convex posts 310 and the second convex posts 410 can also be set to one or more. The plurality of first convex posts 310 are respectively movably embedded in the plurality of first guiding grooves 510, and the plurality of second convex posts 410 are respectively movably embedded in the plurality of second guiding grooves 520. This can enhance the stability when the transmission member 500 moves to drive the stopper 300 and the valve 400 to move.

[0181] In some embodiments, referring to Figure 7 As shown, the driving member 200 of the present disclosure can be set to include a driver 210 and a lead screw 220. Among them, the lead screw 220 is connected to the driver 210, and the axis of the lead screw 220 is arranged parallel to the first direction. The driver 210 can drive the lead screw 220 to rotate, and the transmission member 500 is threadedly connected to the lead screw 220. Correspondingly, when the lead screw 220 rotates, it can drive the transmission member 500 to move along the axis of the lead screw 220. In this way, by driving the lead screw 220 to rotate forward or backward by the driver 210, the transmission member 500 can move along the first direction or the second direction.

[0182] In some embodiments, referring to Figure 13 As shown, the driving member 200 of the present disclosure can also be set to include two drivers 210 and two stay cords 230. Among them, the two stay cords 230 are respectively wound around the drivers 210, and the ends of the two stay cords 230 far from the corresponding drivers 210 are respectively connected to the opposite sides of the transmission member 500.

[0183] Specifically, the driver 210 can be a rotary motor. The driver 210 has a rotating shaft 211, and the pull rope 230 is wound around the rotating shaft of the driver 210. The rotation of the axis of the rotating shaft 211 of the driver 210 can drive the retraction and release of the pull rope 230, and the rotating shaft 211 of the driver 210 can rotate forward and backward. After one of the drivers 210 drives the retraction and release of the pull rope 230, it can pull the transmission member 500 to move in the first direction. At this time, the pull rope 230 on the other driver 210 is released. When one of the drivers 210 drives the retraction and release of the pull rope 230, it can pull the transmission member 500 to move in the second direction. At this time, the pull rope 230 on the other driver 210 is released.

[0184] Through the cooperation of the driver 210 and the pull rope 230, the driver 210 can be arranged behind the floor brush housing 100 or other positions, which can reduce the space occupied by the driving member 200 in the width direction of the floor brush housing 100. In this way, the influence of the driving member 200 on the movement of the transmission member 500 is smaller, and the movement range of the transmission member 500 in the first direction and the second direction is larger.

[0185] In some embodiments, referring to Figure 14 As shown, the driving member 200 of the present application can also be arranged to include a driver 210, a lead screw 220 and a transmission rod 240. The driver 210 is connected to the transmission rod 240, the transmission rod 240 is connected to the lead screw 220, and the transmission member 500 is threadedly connected to the lead screw 220. The driver 210 drives the transmission of the transmission rod 240 to drive the rotation of the lead screw 220. The axis of the transmission rod 240 intersects both the first direction and the third direction, and the axis of the lead screw 220 is parallel to the first direction. The driver 210 can be arranged behind the floor brush housing 100 or other positions, which can reduce the space occupied by the driving member 200 in the width direction of the floor brush housing 100. In this way, the influence of the driving member 200 on the movement of the transmission member 500 is smaller, and the movement range of the transmission member 500 in the first direction and the second direction is larger.

[0186] In some embodiments, referring to Figures 10 to 11 As shown, in order to enable the stopper 300 to be movably connected to the floor brush housing 100, the stopper 300 can also be arranged to include a first limiting portion 320. The floor brush housing 100 has a first limiting groove 140. The depth direction of the first limiting groove 140 is the third direction, and the first limiting portion 320 is movably embedded in the first limiting groove 140. When the stopper 300 moves in the third direction or the fourth direction, the first limiting portion 320 moves in the first limiting groove 140. This can make the stopper 300 move more stably in the third direction and the fourth direction.

[0187] In some embodiments, referring to Figure 10 and Figure 12As shown, in order to enable the valve 400 to be movably connected to the floor brush housing 100, the valve 400 may further be provided with a second limiting portion 420. The floor brush housing 100 has a second limiting groove 150, and the depth direction of the second limiting groove 150 is the fifth direction. The second limiting portion 420 is movably embedded in the second limiting groove 150. When the valve 400 moves along the third direction or the sixth direction, the second limiting portion 420 moves in the second limiting groove 150. This can make the valve 400 move more stably along the fifth direction and the sixth direction.

[0188] In some embodiments, the valve 400 and the stopper 300 may be disposed on opposite sides of the transmission member 500, so that the space on opposite sides of the transmission member 500 can be fully utilized to make the floor brush structure of the present disclosure more compact.

[0189] In some embodiments, referring to Figure 15 As shown, the air inlet 130 of the floor brush housing 100 of the present disclosure is located inside the floor brush housing 100. Correspondingly, the valve 400 is also located inside the floor brush housing 100, which can hide the valve 400 to protect the valve 400. The floor brush housing 100 further has a ventilation port 160, and the ventilation port 160 is located on the surface of the floor brush housing 100. The ventilation port 160 is communicated with the air inlet 130. The air outside the floor brush housing 100 can enter the inside of the floor brush housing 100 through the ventilation port 160 and the air inlet 130 in sequence to adjust the vacuum degree inside the floor brush housing 100.

[0190] In some embodiments, referring to Figure 1 As shown, the floor brush of the present disclosure may further be provided with a dust-proof net 170. The dust-proof net 170 is disposed on the ventilation port 160, and the dust-proof net 170 covers the ventilation port 160. The dust-proof net 170 can prevent dust and foreign matters from entering the inside of the floor brush housing 100 through the ventilation port 160 to a certain extent, achieving the purpose of protecting the floor brush of the present application.

[0191] Based on the above floor brush, the present disclosure also proposes a vacuum cleaner including the above floor brush.
