Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning appliances, and specifically provides a cleaning system which is convenient for drying a roller brush. Background Art

[0002] With the development of cleaning technology, cleaning equipment such as floor scrubbers that can clean the floor and suck out floor dirt have gradually become the mainstream of household cleaning equipment. The floor scrubber includes a body and a floor brush. The lower part of the body is pivotally connected to the rear part of the floor brush. A roller brush is installed at the front of the lower surface of the floor brush. The roller brush can press the floor to be cleaned and rotate to achieve floor cleaning. The floor scrubber is also equipped with a base station to form a cleaning system. The base station is used to realize the functions of supporting, storing and charging the floor scrubber when it is not in a cleaning state. The upper surface of the existing base station has a receiving groove, and the front part of the receiving groove has an air outlet. After the floor brush of the floor scrubber is placed in the receiving groove, the air outlet faces the outer side of the roller brush so that the air outlet can blow out a dry airflow to the roller brush. However, in order to improve the cleaning effect of the roller brush, the roller brush generally protrudes forward from the roller brush cover, which makes a gap between the air outlet and the front part of the roller brush cover. The existence of this gap will cause the dry airflow discharged from the air outlet to overflow.

[0003] In order to solve the above problems, Chinese patent CN216090337U discloses a floor scrubber, which fixes a sealing strip at the air outlet to block the gap between the roller brush cover and the air outlet. The roller brush will squeeze the sealing strip when it descends to enter the receiving groove or rises to leave the receiving groove, causing the sealing strip to deform under force, and the dirt on the roller brush is easy to be contaminated to the inner and outer side walls of the sealing strip; and after long-term use, the sealing strip itself or the connection position between the sealing strip and the base station is easy to wear, so that the sealing strip cannot effectively block the gap. Utility Model Content

[0004] The utility model aims to provide a cleaning system which is convenient for drying a roller brush, and can utilize a movable shielding member to seal the gap between the roller brush cover and the air outlet, and the roller brush will not be obstructed by the shielding member when entering or leaving the receiving groove, thereby reducing the probability of the shielding member being contaminated by dirt on the roller brush, and avoiding the shielding member being repeatedly squeezed by the roller brush and damaged.

[0005] In order to achieve the above-mentioned purpose, one or more embodiments of the utility model provide a cleaning system for drying a roller brush, including a base station and a cleaning device, the cleaning device including a floor brush, a roller brush and a roller brush cover located above the roller brush installed at the front of the housing of the floor brush, the base station having an air outlet and a receiving groove for receiving the roller brush, and the cleaning device docking with the base station to blow out airflow from the air outlet to dry the roller brush. The cleaning system also includes a shielding member movably connected to the base station or the floor brush, the shielding member having a first position and a second position; in the first position, the shielding member does not prevent the roller brush from entering or leaving the receiving groove; in the second position, the shielding member moves to block the gap between the receiving groove and the front of the roller brush cover to prevent the airflow discharged from the air outlet from overflowing.

[0006] In at least one embodiment, the shielding member is integrated with the roller brush cover, the roller brush cover is movably connected to the shell, the shielding member or the roller brush cover is at least partially separated from the shell when in the second position to form a gap opening, the roller brush cover and the shielding member and the outer circular side of the roller brush form an upper flow channel, and the gap opening is connected to the upper flow channel.

[0007] In at least one embodiment, the shielding member is integrated with the roller brush cover, and the rear portion of the shielding member or the roller brush cover remains closed when the floor brush housing is in the second position.

[0008] In at least one embodiment, the shielding member is slidably connected to the base station or the roller brush cover, and the sliding direction of the shielding member is perpendicular to the axial direction of the roller brush.

[0009] In at least one embodiment, the shielding member is rotatably connected to the base station or the roller brush cover, and the rotation axis of the shielding member is parallel to the axial direction of the roller brush.

[0010] In at least one embodiment, the shielding member has a rotation angle range of 15 to 60 degrees relative to the roller brush cover or the base station.

[0011] In at least one embodiment, a linkage member connected to the shielding member is further included, and when the floor brush is docked with the base station, the linkage member can drive the shielding member to move.

[0012] In at least one embodiment, the device further includes a controller and a driving assembly, wherein the controller controls the driving assembly to move the shielding member.

[0013] In at least one embodiment, the shielding member is arc-shaped, and in the second position, the center of the shielding member coincides with the central axis of the roller brush.

[0014] In at least one embodiment, the shielding member further has a third position, and in the third position, the shielding member shields the air outlet at least in the tangential direction of the roller brush to prevent liquid thrown out when the roller brush rotates from entering the air outlet. Beneficial effects of one or more of the above technical solutions:

[0015] (1) In the present solution, a shielding member that is movably connected to the base station or the floor brush is provided in the cleaning system. The shielding member can be moved to a first position and a second position. When in the first position, the shielding member does not hinder the roller brush from entering or leaving the receiving groove, thereby preventing the roller brush from colliding with or being squeezed by the shielding member during the process of the floor brush entering or leaving the receiving groove. On the one hand, this can avoid the probability of the shielding member being directly in contact with the roller brush on the inner and outer sides of the receiving groove and being contaminated by dirt, thereby reducing the need for users to perform additional tedious work of cleaning the shielding member; on the other hand, this can avoid the situation in which the shielding member is damaged and unable to seal the gap due to repeated squeezing and collision with the roller brush; finally, compared with the existing sealing strips, the shielding member in the present solution does not hinder the movement of the roller brush, thereby reducing the labor burden of the user when lifting or lowering the roller brush.

[0016] When in the second position, the shielding member can move to block the gap between the receiving groove and the front part of the roller brush to prevent the airflow discharged from the air outlet from overflowing. When the shielding member is used to block the gap between the air outlet and the roller brush cover, the continuous guide space between the inner wall of the receiving groove on the upper and lower sides of the air outlet, the inner wall of the shielding member, the inner wall of the roller brush cover and the outer side of the roller brush; when reducing the overflow of the dry airflow, the guide space can be used to make the dry airflow flow around the surface of the front part of the roller brush at least, increase the contact area between the dry airflow and the roller brush, and improve the drying effect of the dry airflow on the roller brush.

[0017] (2) In this solution, the shielding member is integrally arranged with the roller brush cover, the roller brush cover is movably connected to the shell, and the shielding member is at least partially separated from the shell in the second position to form a gap opening; the roller brush cover and the shielding member form an upper flow channel with the outer circumferential side of the roller brush, and the gap opening is connected to the upper flow channel. This arrangement can utilize the gap opening to realize the discharge of the dry airflow along the upper flow channel to dry the roller brush, thereby enabling the dry airflow to flow along the upper flow channel in a directional manner and be discharged from the gap opening, thereby avoiding the problem of turbulence in the upper flow channel due to the lack of discharge from the gap opening at the end of the upper flow channel, and avoiding the turbulence in the upper flow channel affecting the subsequent dry airflow blowing toward the roller brush.

[0018] (3) In this solution, the shielding member is integrated with the roller brush cover, and the rear part of the shielding member or the roller brush cover remains closed when the floor brush housing is in the second position. This arrangement can prevent the dry airflow from flowing out of the shielding member and the roller brush cover, so that the dry airflow stays in the shielding member and the roller brush cover for a longer time, increasing the contact area between the dry airflow and the roller brush, and improving the utilization efficiency of the dry airflow.

[0019] (4) In this solution, the shielding member is slidably connected to the base station or the roller brush cover. This arrangement enables the shielding member to switch between the first position and the second position by sliding, thereby facilitating the shielding member to fit the base station or the roller brush cover, reducing the space occupied by the shielding member in the first position, and reducing the probability of position interference between the shielding member and the roller brush and hindering the movement of the roller brush; in addition, the sliding direction of the shielding member is perpendicular to the axial direction of the roller brush. This arrangement can make full use of the spatial size of the roller brush cover or the base station, reducing the difficulty of switching the position of the shielding member by movement.

[0020] (5) In the present embodiment, the shielding member is rotatably connected to the base or the roller brush cover, and the rotation axis of the shielding member is parallel to the axial direction of the roller brush. This arrangement enables the shielding member to switch between the first position and the second position by rotation. The shielding member and the base or the roller brush cover only need to be connected by a rotating shaft without requiring excessive contact area, thereby facilitating a lightweight design of the roller brush cover and the front end of the base station receiving slot.

[0021] (6) In this solution, the range of the rotation angle of the shielding member relative to the roller brush cover or the base station is 15 to 60 degrees. This arrangement can avoid the situation where the shielding member is too small in rotation angle, causing the shielding member to be too small in displacement between the first position and the second position, making it difficult to avoid the roller brush; it can also avoid the situation where the shielding member is too large in rotation angle, causing the shielding member to be too large in displacement between the first position and the second position, making it easy to cause position interference with the roller brush cover or the base station.

[0022] (7) In this solution, the linkage part is connected to the shielding part, and the linkage part can be driven by the floor brush when the floor brush is connected to the base station, and then the linkage part can transmit the driving force to the shielding part to drive the shielding part to switch between the first position and the second position. This setting does not require the additional setting of electric or pneumatic driving parts, which is conducive to saving power and making the structural setting of the floor brush or the base station more concise.

[0023] (8) In this solution, the cleaning system also includes a controller and a drive assembly. This arrangement facilitates using the drive assembly and the controller to adjust the position of the shielding member, thereby preventing the shielding member from affecting the roller brush from entering or leaving the receiving groove.

[0024] (9) In the present embodiment, the shielding member is arc-shaped, and the center of the shielding member in the second position coincides with the central axis of the roller brush. This arrangement makes it easy to make the distance between any position on the shielding member and the outer circular side of the roller brush equal, thereby forming a flow channel with a uniform gap between the shielding member and the roller brush, so that the speed of the airflow in the flow channel is basically equal, and the dry airflow can evenly dry the part of the roller brush close to the flow channel.

[0025] (10) In this embodiment, the shielding member shields the air outlet at least in the tangential direction of the roller brush in the third position to prevent liquid thrown out by the roller brush from entering the air outlet when it rotates. This arrangement can use the shielding member to protect the air outlet, reduce the need for additional cleaning work caused by the air outlet being blocked by dirt, and reduce the labor burden of the user.

[0052] Example 1

[0053] like Figure 1 As shown, this embodiment provides a cleaning system for drying a roller brush, comprising a base station 4 and a cleaning device, the cleaning device comprising a floor brush 5, a roller brush 502 and a roller brush cover 501 located above the roller brush 502 are installed at the front of the housing of the floor brush 5, an air outlet 406 and a receiving groove 404 for receiving the roller brush 502 are provided at the top of the base station 4, and the cleaning device is docked with the base station 4 to blow out airflow from the air outlet 406 to dry the roller brush 502. The cleaning system also includes a shielding member 6 movably connected to the base station 4 or the floor brush 5, and the shielding member 6 has a first position and a second position; in the first position, the shielding member 6 does not prevent the roller brush 502 from entering or leaving the receiving groove 404; in the second position, the shielding member 6 moves to block the gap 7 between the receiving groove 404 and the front of the roller brush cover 501 to prevent the airflow discharged from the air outlet 406 from overflowing.

[0054] Specifically, the cleaning device includes a floor brush 5 and a body 3, the rear of the floor brush 5 is pivotally connected to the lower part of the body 3, and the upper end of the body 3 is provided with a handle bar 2 and a handle 1. The user holds the handle 1 to lift or lower the body 3 and the floor brush 5, and then places the floor brush 5 in the receiving groove 404 on the upper surface of the base station 4, or makes the floor brush 5 detach from the receiving groove 404. The aforementioned receiving groove 404 is used to accommodate the roller brush 502, which means that at least part of the structure of the roller brush 502 is placed in the receiving groove 404.

[0055] In this embodiment, the front end of the base station 4 has a front edge 402, and the front edge 402 is used to define the front boundary of the receiving groove 404. The side wall or top wall of the front edge 402 facing the receiving groove 404 is provided with an air outlet 406, and the air outlet 406 is connected to the air supply component inside the base station 4. In the process of placing the floor brush 5 on the base station 4 for self-cleaning of the roller brush 502, the water tank of the floor brush 5 supplies water to the roller brush 502, the roller brush 502 rotates, and the vacuum assembly sucks the dirt on the roller brush 502 into the sewage bucket on the fuselage 3. At the same time, a dry airflow is blown out from the air outlet 406 toward the roller brush 502. In some embodiments, the airflow blown out by the air supply component is a high-temperature airflow to accelerate the drying of the roller brush 502.

[0056] In this embodiment, the floor brush 5 includes a shell, the shell includes an upper shell and a lower shell, and the upper shell and the lower shell enclose an installation cavity. A roller brush cavity is installed at the front of the shell, and a roller brush 502 is rotatably connected in the roller brush cavity, and a roller brush cover 501 is detachably installed on the upper part of the roller brush 502. The roller brush 502 can be exposed or covered by disassembling the roller brush cover 501, so as to facilitate the disassembly of the roller brush 502; in order to increase the cleaning effect, the front end of the roller brush 502 will protrude forward from the roller brush cover 501, that is, the front end of the vertical projection of the roller brush 502 is located at the front side of the vertical projection of the roller brush cover 501. After the floor brush 5 is placed on the base station 4, the front end of the roller brush 502 is close to the air outlet 406 on the front edge 402, and a gap 7 is formed between the front end of the roller brush cover 501 and the front edge 402 and the air outlet 406. The dry airflow discharged from the air outlet 406 is easy to overflow from the gap 7, thereby reducing the drying effect of the base station 4 on the roller brush 502.

[0057] If a flexible (for example, silicone) sealing piece is fixedly arranged between the air outlet 406 and the roller brush cover 501, after the floor brush 5 is placed on the base station 4, part of the structure of the sealing piece must cover the upper part of the roller brush 502, that is, when the floor brush 5 is lifted up to leave the accommodating cavity, the roller brush 502 and the inner side surface of the sealing piece will be squeezed against each other, and when the floor brush 5 is lowered into the accommodating cavity, the roller brush 502 and the inner side surface of the sealing piece will be squeezed against each other; that is, the sealing piece is easily contaminated with dirt and damaged in the process of contact and mutual squeezing with the roller brush 502.

[0058] As mentioned above, in this embodiment, the shielding member 6 is movably connected to the base station 4 or the floor brush 5, that is, the shielding member 6 can move relative to the base station 4 or the floor brush 5 connected thereto, thereby avoiding the movement of the roller brush 502 in the first position, and blocking the gap 7 between the air outlet 406 and the roller brush cover 501 in the second position. In this process, the shielding member 6 does not hinder the movement of the roller brush 502, thereby avoiding the extrusion and position interference between the shielding member 6 and the roller brush 502, and the probability of dirt being contaminated on the shielding member 6.

[0059] As a specific structural form, in this embodiment, the shielding member 6 is integrated with the roller brush cover 501, and the roller brush cover 501 is movably connected to the shell. When the shielding member 6 or the roller brush cover 501 is in the second position, it is at least partially separated from the shell to form a gap opening 503. The outer circular side surfaces of the roller brush cover 501, the shielding member 6 and the roller brush 502 form an upper flow channel 405, and the gap opening 503 is connected to the upper flow channel 405.

[0060] For details, see Figure 2-Figure 7, the shielding member 6 and the roller brush cover 501 have no obvious structural boundary, and the two are manufactured in an integrally formed manner. It can be understood that part of the structure at the front end of the roller brush cover 501 is the shielding member 6. The roller brush cover 501 is movably connected to the shell. The movable connection here can be understood as a sliding connection, a rotating connection or a plurality of snap-on connection. Take the sliding connection between the roller brush cover 501 and the shell as an example: a corresponding locking structure is provided between the roller brush cover 501 and the shell, and the roller brush cover 501 can slide relative to the shell, so that the shielding member 6 at the front end of the roller brush cover 501 can switch between the first position and the second position and be positioned by the locking structure. When the shielding member 6 is in the second position, the rear portion of the roller brush cover 501 is separated from the shell to form a gap opening 503, and the gap opening 503 is connected to the above-mentioned upper flow channel 405. As a possible setting method, such as Figure 7 As shown, part of the gas from the air outlet can be blown upward along the upper flow channel 405 toward the roller brush and finally discharged from the gap opening 503 in a directional manner, so that the dry airflow flows smoothly in the upper flow channel 405 to avoid the generation of turbulence. As another possibility of this setting, during drying, the vacuum assembly works so that the airflow from the air outlet 406 flows along the path below the roller brush toward the sewage suction port and forms a negative pressure in the roller brush chamber. The generation of negative pressure also enables the external airflow to enter from the gap opening 503, along the outer surface of the roller brush, mix with the airflow from the air outlet 406, and then flow along the path below the roller brush toward the sewage suction port. More specifically, the shape and size of the gap opening 503 here can be set by those skilled in the art, for example, it can be a square opening or a diamond opening.

[0061] See also Figure 8 In some other embodiments, when the shielding member 6 is integrated with the roller brush cover 501, the roller brush cover 501 is movably connected to the housing, and the rear portion of the shielding member 6 or the roller brush cover 501 can also remain closed relative to the housing of the floor brush 5 when in the second position. This arrangement can prevent the dry airflow entering from the flow channel from being discharged from the gap opening 503, thereby increasing the residence time of the dry airflow in the upper flow channel 405.

[0062] In this embodiment, a controller and a driving component are also included, and the controller controls the driving component to drive the shielding member 6 to move. The controller here can be a single chip microcomputer, an ARM processor or a PLC controller, etc., which can be set by those skilled in the art.

[0063] Specifically, taking the sliding connection between the roller brush cover 501 and the floor brush 5 as an example, the driving assembly adopts an electric push rod (not shown in the figure), the electric push rod includes a driving rod and a fixed base, the driving rod can be extended relative to the fixed base, the driving rod is connected to the roller brush cover, and the fixed base is connected to the housing of the floor brush. After the driving rod of the electric push rod is extended relative to the fixed base, it can push the shielding member 6 at the roller brush cover 501 to move forward to the second position, thereby making the shielding member 6 abut against the front edge 402 on the base station 4. When the electric push rod retracts relative to the fixed base, it can pull the shielding member 6 at the front end of the roller brush cover 501 to move backward to the first position, thereby making the roller brush cover 501 and the front edge 402 of the base station 4 and the air outlet 406 thereon have the gap 7, and the roller brush cover 501, the shielding member 6, the roller brush 502 and the base station 4 will not hinder each other during the process of lifting and lowering the floor brush 5.

[0064] Taking the roller brush cover 501 and the floor brush 5 as an example, the roller brush cover 501 is rotatably connected to the housing of the floor brush 5 via a rotating shaft, and the driving assembly also uses an electric push rod, the driving rod of the electric push rod is connected to the side of the roller brush cover away from the shielding member via a deformable flexible rod, and the fixed base of the electric push rod is rotatably connected to the housing of the floor brush. The electric push rod can push the entire roller brush cover 501 to rotate, thereby causing the roller brush cover 501 to tilt forward to the position where the front shielding member 6 abuts against the front side 402, or tilt backward to form a gap 7 between the shielding member 6 and the front side 402.

[0065] In some other embodiments, the driving component can also adopt other structures. For example, the driving component is a combination of an electromagnet and a metal spring. The elastic force of the metal spring drives the roller brush cover 501 and the shielding member 6 to move forward. The two parts of the electromagnet are respectively installed on the housing of the floor brush 5 and the shielding cover. The electromagnet can provide power for the roller brush cover 501 to move backward.

[0066] In this embodiment, in order to reduce the movement range of the roller brush cover 501, an extension plate 401 is fixedly provided on the front edge 402 of the base station 4, and the extension plate 401 protrudes upward relative to the front edge 402. The extension plate 401 also protrudes toward the inner side of the accommodating groove 404. However, the distance that the extension plate 401 protrudes toward the inner side of the accommodating groove 404 is such that it will not collide with the roller brush 502 and the roller brush cover 501 during the process of lifting or lowering the roller brush 502 and the floor brush 5.

[0067] In this embodiment, the shielding member 6 is arc-shaped, and in the second position, the center of the shielding member 6 coincides with the central axis of the roller brush 502. In this arrangement, the shielding member 6 is an arc-shaped plate, the inner arc surface of the arc-shaped plate faces the roller brush 502, and the arc-shaped plate and the roller brush 502 are arranged coaxially, so that the upper flow channel 405 is an arc-shaped flow channel with uniform gaps 7 at various locations, and the arc-shaped flow channel is formed by the outer circular side surface of the roller brush 502 and the arc-shaped plate. This can avoid the different drying effects of the drying airflow and the roller brush 502 corresponding to each position of the upper flow channel 405 caused by the different thickness of the gap 7 of the upper flow channel 405, and facilitate the uniform drying of the roller brush 502.

[0068] In addition, in this embodiment, a lower flow channel 403 is formed between the lower half of the outer circular side of the roller brush 502 and the lower wall of the receiving groove 404. The airflow blown out from the air outlet 406 is divided into an upper flow channel 405 and a lower flow channel 403 to respectively bypass the upper and lower outer circular sides of the roller brush 502 for drying, thereby increasing the drying area of ​​the drying airflow and improving the drying effect of the roller brush 502.

[0069] See also Fig. 9 In this embodiment, the shielding member 6 also has a third position. In the third position, the shielding member 6 shields the air outlet 406 at least in the tangential direction of the roller brush 502 to prevent the liquid thrown out when the roller brush 502 rotates from entering the air outlet 406. Specifically, when the roller brush 502 performs a self-cleaning process, the shielding member 6 first rotates to the third position to block the air outlet 406, and then the roller brush 502 rotates, and the dirt suction port on the floor brush absorbs the dirt scraped from the surface of the roller brush; the dirt thrown out from the surface of the roller brush 502 along the tangential direction toward the air outlet 406 will splash to the inner side of the shielding member 6 to be blocked. When the roller brush 502 needs to be air-dried after self-cleaning, the shielding member 6 moves to the second position to expose the air outlet 406.

[0070] In this embodiment, a linkage member is further included, and when the floor brush 5 is docked with the base station 4, the linkage member can drive the shielding member 6 to move. The linkage member is connected to the shielding member, or the linkage member and the shielding member are integrally formed. When the shielding member is installed on the base station, the contact between the floor brush and the linkage member can drive the linkage member to move; when the shielding member is installed on the shielding cover, the contact between the base station and the linkage member can drive the linkage member to move.

[0072] The structural arrangement of this embodiment is basically the same as that of Embodiment 1, except that in this embodiment, the shielding member 6 is rotatably connected to the base station 4 or the roller brush cover 501 , and the rotation axis of the shielding member 6 is parallel to the axial direction of the roller brush 502 .

[0073] Take the rotatable connection between the shielding member 6 and the base station 4 as an example, see Figure 10-Figure 14The mounting seat 408 at the upper end of the front side 402 of the base station 4 is rotatably connected to the lower end of the shielding member 6 through the pivot shaft 602, and the upper end of the shielding member 6 extends freely. There are two mounting seats 408, which are respectively arranged at the left and right ends of the front side 402. Figure 11-Figure 12 At this time, the upper end of the shielding member 6 rotates outward relative to the receiving groove 404, and thus does not hinder the movement of the roller brush 502 during the lifting and lowering process of the floor brush 5. Fig.10 as well as Fig.13 and Fig.14 As shown, at this time, the upper end of the shielding member 6 rotates inward relative to the accommodating groove 404, and then after the roller brush 502 of the floor brush 5 is placed in the accommodating groove 404, part of the structure of the upper end of the shielding member 6 is located above the roller brush 502 and docked with the roller brush cover 501 to cover the gap 7 between the roller brush cover 501 and the air outlet 406.

[0074] In some other embodiments, the upper end of the shielding member 6 is rotatably connected to the front end of the roller brush cover 501, and the shielding member 6 can be rotated and positioned relative to the roller brush cover 501. During normal cleaning of the floor brush 5, and during the lifting of the floor brush 5 so that the roller brush 502 descends to the receiving groove 404 or leaves the receiving groove 404, the shielding member 6 rotates upward until the vertical projection of the shielding member 6 does not exceed the roller brush 502. When the floor brush 5 is placed on the base station 4 for self-cleaning, the free end of the shielding member 6 rotates downward to dock with the front edge 402 of the base station 4 to block the gap 7 between the air outlet 406 and the roller brush cover 501.

[0075] In this embodiment, the rotation angle range of the shielding member 6 relative to the roller brush cover 501 or the base station 4 is 15 degrees to 60 degrees. Specifically, the rotation angle range may be 15 degrees, 30 degrees or 60 degrees.

[0076] See again Figure 11-Figure 14 This embodiment provides a specific structural form of the linkage member: the lower end of the shielding member 6 is fixedly connected to the linkage member 601, and the linkage member 601 will stop at the linkage member 601 during the descent of the floor brush 5, and then the linkage member 601 drives the upper end of the shielding member 6 to rotate toward the roller brush 502. When the roller brush 502 is completely placed in the receiving groove 404, the linkage member 601 drives the shielding member 6 to move to dock with the roller brush cover 501.

[0077] In some other embodiments, the structural setting of the linkage member 601 can be set by those skilled in the art and will not be described in detail here.

[0078] Example 3

[0079] The structural arrangement of this embodiment is basically the same as that of Embodiment 1, except that in this embodiment, the shielding member 6 is slidably connected to the base station 4 or the roller brush cover 501 , and the sliding direction of the shielding member 6 is perpendicular to the axial direction of the roller brush 502 .

[0080] See also Figure 15-18 , taking the sliding connection between the shielding member 6 and the base station 4 as an example: the front edge 402 at the front of the base has a sliding cavity 407, and the shielding member 6 is nested in the sliding cavity, and the sliding cavity passes through the upper wall of the front edge 402 upward. The shielding member 6 can slide upward and protrude from the front edge 402 to be located in the second position, so that the upper end of the shielding member 6 abuts against the front end of the roller brush cover 501; the shielding member 6 can also slide downward to be retracted in the front edge 402 and then be located in the first position, so that the shielding member 6 will not hinder the lifting of the roller brush 502.

[0081] Take the sliding connection between the shielding member 6 and the roller brush cover 501 as an example (not shown in the figure): in this case, the shielding member 5 is separated from the base station 4 and the roller brush cover 501. The front end of the roller brush cover 501 has a slide groove or a sliding cavity, and the shielding member is slidably connected to the roller brush cover 501 through the slide groove or the sliding cavity. The driving component is arranged between the roller brush cover 501 and the shielding member 6, and the shielding member 6 can be pushed forward and backward by the driving component, so that the shielding member 6 can abut against the front edge 402 of the base station 4 or the extension plate 401 on the front edge 402 to block the gap 7 between the air outlet 406 and the roller brush cover 501.

[0082] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments of the foregoing text, but it is easy for those skilled in the art to understand that the protection scope of the present application is not limited to the above preferred embodiments. Without departing from the technical principles of the present application, those skilled in the art may split and combine the technical solutions in the above preferred embodiments, and may also make equivalent changes or replacements to the relevant technical features, and any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present application will fall within the protection scope of the present application.
