The air duct inlet 1121 may be provided with an air intake filter 141, which can filter the air flow passing through the air duct inlet 1121, so that dust, trash, and other garbage objects are blocked in the dust cup 12 and cannot enter the air outlet 112, and the filtered air flow can flow out through the air duct outlet 1122. The air duct outlet 1122 may further be provided with an air outlet filter 142 for filtering the airflow flowing out to the outside, so as to improve the cleanliness of the airflow flowing out to the environment. The device body 10 may also include a control circuit board 15 and an air volume indicator 16, the control circuit board 15 may be coupled with the motor 13 and the air volume indicator 16. The control circuit board 15 can acquire the air quantity data indicated by the air quantity indicator 16 to adjust the operating power of the motor 13.

The housing 11 may be an assembled housing 11, that is, the housing 11 may be disassembled into a plurality of sub-housings, and then the parts inside the housing 11 may be disassembled. For example, the dust cup 12 can be taken out after the housing 11 is detached, the dust cup 12 can be cleaned by pouring out the dust in the dust cup 12, the motor 13 can be repaired, and the air outlet duct 112 can be cleaned.

As shown in fig. 1, for the mobile robot type dust suction apparatus 1, the apparatus main body 10 may further include rollers 17 provided at the bottom of the housing 11 for traveling on a work surface, a floor, or the ground, thereby making the dust suction apparatus 1 mobile. Dust extraction 1 can also include tuber pipe 18, and air intake 111 is connected to the one end of tuber pipe 18, and the other end connects brush head assembly 20, and then makes air intake 111 and brush head assembly 20 intercommunication to can make brush head assembly 20 have the adsorption affinity when motor 13 work forms the air current, and then can absorb rubbish objects such as dust, miscellaneous bits, and rubbish objects such as dust, miscellaneous bits can enter into dirt cup 12 through tuber pipe 18, and then remain in dirt cup 12. For the mobile robot cleaner 1, the air duct 18 may be a soft air duct, and may have a long length.

As shown in fig. 2, in the hand-held type dust suction apparatus 1, the roller 17 may not be provided, and the apparatus main body 10 may include a handle 19 connected to the housing 11 for a user to hold, as compared to the movable robot type dust suction apparatus 1. The handle 19 may be integrally formed with the housing 11. Of course, in some embodiments, the roller 17 may be further provided on the basis of the handle 19. The hand-held dust collector 1 may not be provided with the air pipe 18, and then the brush head assembly 20 is directly mounted with the air inlet 111, and further the two are communicated, of course, the air pipe 18 may also be provided, and the air pipe 18 may be a hard air pipe or a soft air pipe.

The above-described device body 10 is merely an exemplary illustration, and does not limit the specific structure and configuration of the device body 10 of the present application, and the specific structure and configuration of the device body 10 may be of other types.

As shown in fig. 1-3, brushhead assembly 20 may include a hub 21 and a brushhead 22. The brush head 22 is connected to the device body 10 through the bushing 21. For example, a bushing 21 may be connected between the air hose 18 and the brush head 22. Of course, as mentioned above, the brush head 22 can also directly communicate with the air inlet 111 through the sleeve 21.

Specifically, the brush head 22 may include a bracket 221 and a brush plate assembly 222 coupled to the bracket 221. The support 221 may be disposed in a column shape, such as a cylinder, an elliptic cylinder, a square column, or other polygonal column. The bracket 221 may be formed with through holes 2210 passing through opposite sides thereof. For example, the holder 221 may be formed with a through hole 2210 along a length direction thereof, the through hole 2210 penetrating both end surfaces (side surfaces), i.e., the above-mentioned opposite sides.

The brush plate assembly 222 is attached to the bracket 221. As shown in FIG. 4, the brush plate assembly 222 is formed with passages 2220 communicating with the through holes 2210. As shown in fig. 1 to 4, when the motor 13 is operated, a negative pressure is formed in the dust cup 12, the through hole 2210 and the passage 2220 communicating with the dust cup 12 are also formed, and external dust can be sucked through the passage 2220 and the through hole 2210 in sequence, and finally can enter the dust cup 12.

In order to adjust the cleaning angle of the brush head 22, which is convenient for the user to deal with different cleaning scenes when using the dust suction device 1, the angle between the brush head 22 and the shaft sleeve 21 can be set to be adjustable. Specifically, the angle between the axial direction of the bracket 221 and the axial direction of the boss 21 is adjustable. For example, one end of the bracket 221 is connected to the brush plate assembly 222, the other end of the bracket 221 is connected to the shaft sleeve 21, and the included angle between the axial direction of the through hole 2210 and the axial direction of the shaft sleeve 21 is adjustable, so that the included angle can be adjusted for reuse according to actual requirements.

For example, the sleeve 21 is a flexible sleeve 21 that can be bent, and after the sleeve 21 and the bracket 221 are connected and fixed, the working angle of the bracket 221 can be changed by bending the sleeve 21 by a corresponding angle. For example, the boss 21 and the bracket 221 are connected by a flexible member, and the angle between the boss 21 and the bracket 221 is changed by bending the flexible member.

For example, the bracket 221 and the bushing 21 are rotatably connected end-to-end. That is, one end of the holder 221 abuts one end of the sleeve 21, and the holder 221 and the sleeve 21 can relatively rotate, so that the angle between the axial direction of the through hole 2210 and the axial direction of the sleeve 21 can be adjusted.

As shown in fig. 4 and 5, the end surface of the holder 221 away from the head 22 may be disposed obliquely with respect to the axial direction of the holder 221. The axial direction of the holder 221 may refer to the longitudinal direction of the holder 221, and may also refer to the axial direction of the through hole 2210. The end surface of the boss 21 near the holder 221 may be disposed obliquely with respect to the axial direction of the boss 21. The end face of the bracket 221 remote from the head 22 and the end face of the sleeve 21 adjacent to the bracket 221 are connected in contact, i.e. end-to-end as described above. The holder 221 is rotatable about the axis of the holder 221 relative to the boss 21 so that the holder 221 and the boss 21 can be rotatably coupled.

The inclined fit between the end surface of the bracket 221 far away from the brush head 22 and the end surface of the shaft sleeve 21 close to the bracket 221 enables the included angle between the extending direction of the bracket 221 and the extending direction of the shaft sleeve 21 to be adjustable. For example, the inclination of the end surface of the holder 221 away from the brush head 22 with respect to the axial direction of the holder 221 is the same as or substantially the same as the inclination of the end surface of the boss 21 close to the holder 221 with respect to the axial direction of the boss 21, and the holder 221 rotates around its axis, so that the fitting position of the end surfaces of the two changes.

The end of the support 221 remote from the head 22 may have a high point and a low point, the high point being the outermost point and the low point being the innermost point, and the end of the sleeve 21 adjacent to the support 221 may likewise have a high point and a low point. As shown in fig. 4, when the end surface of the holder 221 and the end surface of the boss 21 overlap or substantially overlap at the high-low point, the axial direction of the holder 221 and the axial direction of the boss 21 overlap or substantially overlap. As shown in fig. 5, when the end surface of the bracket 221 and the end surface of the boss 21 are overlapped at the high point and the low-low point, respectively, or substantially, the angle between the axial direction of the bracket 221 and the axial direction of the boss 21 is a predetermined angle. Specifically, when the above-mentioned end surface of the holder 221 and the above-mentioned end surface of the boss 21 achieve high-low point coincidence or substantial coincidence, the angle between the axial direction of the holder 221 and the axial direction of the boss 21 is 0 ° or substantially 0 °, and when the above-mentioned end surface of the holder 221 and the above-mentioned end surface of the boss 21 achieve high point coincidence and low-low point coincidence or substantial coincidence, the angle between the axial direction of the holder 221 and the axial direction of the boss 21 is the largest. That is, the axial direction of the bracket 221 and the axial direction of the boss 21 are adjustable between 0 ° and a preset angle.

The included angle between the axis direction of the support 221 and the axis direction of the shaft sleeve 21 is adjustable, the use angle of the support 221 can be flexibly adjusted, and then the working angle of the brush head 22 can be adjusted, so that different cleaning environments and requirements can be adapted, and the use of a user is facilitated.

In order to improve the flexibility of the operation of the brush head 22 and to cope with more different cleaning scenes, the brush plate assembly 222 of the present embodiment may be configured in a split type, so that various structural configurations can be formed through different combinations, and thus different operation modes can be formed.

As shown particularly in fig. 6, the brush plate assembly 222 can include two brush plates 2221 that can be coupled together. The two brush plates 2221 may be rotatably coupled to the holder 221, respectively. Opposite sides of the two brush plates 2221 are each formed with a through groove 22210 communicating with the through hole 2210. In this embodiment, the side of each of the two brush plates 2221 opposite to each other is an opposite side of the brush plate 2221, and the side of each of the two brush plates 2221 facing away from each other or facing away from the opposite side is an opposite side of the brush plate 2221. Specifically, the brush plate 2221 may form a through groove 22210 along the length direction thereof, that is, both ends of the through groove 22210 in the length direction of the brush plate 2221 are in an open state, not in a closed state. The two brush plates 2221 may be rotated with respect to the holder 221, respectively, so that opposite sides of the two brush plates 2221 can be coupled to each other or can be spread apart from each other. The through grooves 22210 formed in the respective two brush plates 2221 are fitted to form the passages 2220 when the respective opposite sides of the two brush plates 2221 are coupled to each other.

One end of the channel 2220 formed by splicing can be communicated with the shaft sleeve 21 so as to be communicated with the air inlet 111, and the other end can be communicated with the outside so as to be close to garbage objects such as dust, sundries and the like to be cleaned. When the motor 13 works, the other end passage opening of the passage 2220 forms negative pressure, so that dust, sundry scraps and other garbage objects can be sucked, and the cleaning device can adapt to the narrow condition of a clean environment. For example, the gap of a sofa, the gap of a door or a window, the gap of furniture, etc., the suction end (the passage opening at the other end of the passage 2220) of the brush plate assembly 222 formed by splicing the two brush plates 2221 has a smaller area, so as to be convenient to approach or extend into a narrower clean environment, and effectively suck dust, sundry bits, etc. in the clean environment. The two brush plates 2221 are opened to each other, so that the suction area of the dust suction apparatus 1 can be increased, and thus, the dust suction apparatus can be applied to a case where a clean environment is spacious. The cleaning efficiency is improved.

Of course, the two brush plates 2221 may each be rotated independently relative to the holder 221. The two brush plates 2221 may be linked, and when one brush plate 2221 rotates relative to the bracket 221, the other brush plate 2221 also rotates relative to the bracket 221. Each brush plate 2221 may be a complete brush plate 2221, or may be formed by combining a plurality of sub-brush plates, that is, the brush plate assembly 222 of the present application does not have to include only two brush plates 2221, but may substantially include a plurality of brush plates 2221, and may be set according to specific requirements.

There are various ways in which the two brush plates 2221 can rotate relative to the holder 221. As shown in fig. 6, the two brush plates 2221 may be rotatably coupled to one end of the holder 221 by means of the rotating member 223, respectively. The two brush plates 2221 can rotate around the rotating members 223, respectively, with respect to the bracket 221. The rotating member 223 may be a hinge, and the brush plate 2221 and the holder 221 may be hinged, so that the relative rotation may be achieved. The rotating member 223 may be a shaft, and the shaft is connected between the two brush plates 2221 and one end of the bracket 221, for example, one end of the bracket 221 is provided with a shaft receiving hole and/or the two brush plates 2221 are provided with shaft receiving holes, so that the shaft can rotate in the shaft receiving holes, and the rotatable connection between the brush plates 2221 and the bracket 221 is realized.

As shown in FIG. 7, each of the two brush plates 2221 may be close to or offset from the axis of the through hole 2210 during the rotation around the rotation member 223, thereby allowing the opposite sides of each of the two brush plates 2221 to be coupled to or spread apart from each other. Specifically, when the two brush plates 2221 are rotated at the axis near the through-holes 2210 of the holder 221 at predetermined positions, opposite sides of the two brush plates 2221 may be contact-coupled, so that the through grooves 22210 of the two can be spliced to form the passages 2220. Opposite sides of the two brush plates 2221 are opened to each other by being rotated continuously away from the axis of the through hole 2210 from a predetermined position.

The two brush plates 2221 which can be connected in a split manner are arranged, so that the two brush plates 2221 can rotate relative to the bracket 221, opposite sides of the two brush plates 2221 can be connected with each other or can be opened with each other in the rotation process relative to the bracket 221, opposite sides of the two brush plates 2221 are connected with each other, so that the through grooves 22210 of the two brush plates 2221 are split into the channels 2220, and thus, the narrow cleaning environment can be adapted to, and the narrow nozzle mode can be defined, and the opposite sides of the two brush plates 2221 are opened with each other, so that the suction area of the brush head 22 can be increased, the wide cleaning environment can be adapted, the suction efficiency can be effectively increased, and the wide nozzle mode can be defined. The two brush plates 2221 can flexibly change the shape of the brush head 22 by rotating relative to the bracket 221, so that different working modes of the brush head 22 can be switched, and the use efficiency and the cleaning efficiency of the brush head 22 are improved.

Further, the two brush plates 2221 may be close to or offset from the axis of the through hole 2210 by rotating around the rotating member 223, and the connection or spread of the two brush plates 2221 to each other may be more stably accomplished.

Specifically, the number of the rotating members 223 may be two groups, each group including at least one rotating member 223. Two sets of rotation members 223 may be disposed at one end of the bracket 221, respectively, and the two sets of rotation members 223 may be disposed at intervals and fixed at one end of the bracket 221. The rotation member 223 may have a cylindrical shape or a shaft shape, and one end of the rotation member 223 is fixed to one end of the bracket 221 and the other end is a free end. Taking the example that each set includes one rotating element 223, two rotating elements 223 may be disposed at an end of the bracket 221 side by side at intervals and fixed to an end of the bracket 221.

As shown in fig. 6, one end of each of the two brush plates 2221 may be provided with a slide hole 22211 extending along the through slot 22210, that is, the slide hole 22211 is a strip-shaped slide hole 22211. The slide hole 22211 may be a through hole 2210, or may be a blind hole. Specifically, the brush plate 2221 may have a bottom wall 2221a and side walls 2221b connected to both sides of the bottom wall 2221a, the bottom wall 2221a and the side walls 2221b are enclosed to form a through groove 22210, and a slide hole 22211 is opened in the side walls 2221 b. The rotating members 223 are inserted into the sliding holes 22211 of the brush plate 2221, and are slidable in the sliding holes 22211. The number of the rotating members 223 of each set of rotating members 223 may be the same as the number of the sliding holes 22211 of each brush plate 2221.

Taking each set of rotating members 223 comprising one rotating member 223 as an example, one side wall 2221b of the brush plate 2221 is provided with a sliding hole 22211. The rotating member 223 can be inserted into the sliding hole 22211 of the corresponding brush plate 2221. Specifically, the other end (free end) of the rotating member 223 may be inserted into the slide hole 22211, and may slide in the respective corresponding slide holes 22211. The rotating member 223 slides in the slide hole 22211 so that the brush plate 2221 can slide with respect to the holder 221. Also, one end of the brush plate 2221 may be rotated about the rotating member 223 to be close to or offset from the axis of the through hole 2210, so that the two brush plates 2221 may be coupled to each other or spread apart from each other. In this embodiment, the side walls 2221b of the two brush plates 2221, which are provided with the sliding holes 22211, may be located at the same side or at different sides, and correspondingly, the rotating element 223 corresponding to each brush plate 2221 may be disposed at the same side of the bracket 221 or at different sides of the bracket 221.

Taking each set of rotating members 223 comprising two rotating members 223 as an example, the two side walls 2221b of the brush plate 2221 are both provided with sliding holes 22211. One rotating member 223 is correspondingly fitted into the sliding hole 22211 of one side wall 2221b, and accordingly, the two rotating members 223 of the set are respectively disposed at both sides of the holder 221 such that the sliding holes 22211 of both side walls 2221b of each brush plate 2221 are respectively slidably fitted with the two rotating members 223 at both sides of the holder 221, so that the brush plate 2221 can be slid with respect to the holder 221, and further, one end of the brush plate 2221 can be rotated about the two rotating members 223 to be close to or away from the axis of the through-hole 2210, so that the two brush plates 2221 can be coupled to or spread apart from each other.

The rotating member 223 may be limited to slide in the sliding hole 22211 without being separated from the sliding hole 22211, so that the brush plate 2221 may be supported and fixed by the rotating member 223.

Through the sliding fit of the rotating part 223 and the sliding hole 22211, the brush board assembly 222 and the bracket 221 can slide relatively, so that a structure similar to a telescopic structure is formed between the brush board assembly 222 and the bracket 221, and further the total length of the brush head 22 can be changed, and different use scenes can be further adapted, furthermore, the rotating part 223 can rotate in the sliding hole 22211, and further the brush board 2221 can be close to or deviate from the axis of the through hole 2210, the structure is simple and more stable, so that the two brush boards 2221 can be stably connected with each other or opened with each other, the structural form of the brush head 22 can be flexibly switched, and different working modes can be used to adapt to different cleaning environments.

There are various positions for the rotating member 223, and there are various matching forms of the corresponding brush plate 2221 and the holder 221. The present embodiment exemplarily provides the following situations:

the first case: as shown in fig. 6 and 7, the rotating member 223 is disposed on the inner surface of the bracket 221, and may be an inner surface surrounding the through hole 2210, or may be a groove side wall surface 2212 as described below, and one end of the brush plate 2221 may be inserted into the bracket 221, so that the rotating member 223 is slidably engaged with the slide hole 22211.

For example, one end of the bracket 221 may be formed with a mounting groove 2211. The mounting groove 2211 has openings 2214 penetrating through opposite sides of the bracket 221 in a direction perpendicular to the extending direction of the through hole 2210. The vertical direction of the through hole 2210 direction may refer to a vertical or substantially vertical direction. One end of the bracket 221 has a groove bottom wall surface 2213 enclosing the mounting groove 2211 and groove side wall surfaces 2212 connected to both sides of the groove bottom wall surface 2213. The through hole 2210 may communicate with the mounting groove 2211 through the groove bottom wall surface 2213 of the mounting groove 2211, i.e., the mounting groove 2211 communicates with the through hole 2210 through the groove bottom wall surface 2213.

As shown in fig. 7 and 8, taking as an example that each set of the rotating members 223 includes two rotating members 223, the two rotating members 223 of each set are protrudingly provided on two oppositely provided groove side wall surfaces 2212 of the mounting groove 2211. Specifically, the rotation member 223 may be provided to the groove-side wall surface 2212 located between the two openings 2214. The rotators 223 of the two sets of rotators 223 on the same slot side wall surface 2212 may be arranged side by side at intervals. One end of the brush plate 2221 is inserted into the mounting groove 2211 to be engaged with the corresponding rotating member 223. One end of the brush plate 2221 may be close to or far from the groove bottom wall surface 2213 by the sliding engagement of the rotating member 223 and the sliding hole 22211.

When one end of the brush plate 2221 is moved close to the groove bottom wall surface 2213 so that the rotation member 223 is slid to the first position of the slide hole 22211, the respective opposite sides of the two brush plates 2221 are connected to each other. In other words, as one end of the brush plate 2221 is moved toward the bottom wall 2213 to a corresponding position (e.g., as the one end of the brush plate 2221 is moved to a position where it can no longer move further toward the bottom wall 2213), the rotating member 223 is located at a first position of the sliding hole 22211, at which time, the respective opposite sides of the two brush plates 2221 are in contact with each other, so that the two through slots 22210 are combined into the channel 2220.

When one end of the brush plate 2221 is moved away from the groove bottom wall surface 2213 so that the rotating member 223 slides to the second position of the slide hole 22211, the brush plate 2221 can rotate around the rotating member 223. In other words, one end of the brush plate 2221 is moved away from the groove bottom wall surface 2213 to a corresponding position (e.g., the end of the slide plate is moved to a position where it cannot move further away from the groove bottom wall surface 2213), and the rotating member 223 is located at a second position of the slide hole 22211, where the brush plate 2221 can rotate around the rotating member 223 and opposite sides of the two brush plates 2221 can be opened apart from each other.

Through seting up mounting groove 2211 in the one end of support 221, rotate the piece 223 and set up in groove side wall 2212, brush board 2221 rotates the in-process for rotating the piece 223 for, the structure of running through of mounting groove 2211 can form keeping away the position to brush board 2221, so can enlarge the range that opens each other of two brush boards 2221, can adapt to more clean scenes and user's demand.

The second case: as shown in fig. 9, the rotator 223 is disposed on the outer side surface of the bracket 221. Specifically, one end of the rotation member 223 is fixed to the outer side of the bracket 221, and the other end of the rotation member 223 extends away from the outer side of the bracket 221.

Taking the example that each set of rotating parts 223 includes two rotating parts 223, the two rotating parts 223 of each set are respectively disposed on two outer side surfaces of the bracket 221, which are disposed opposite to each other (even if the bracket 221 is cylindrical, the cylindrical surface may be exemplarily divided into a plurality of outer side surfaces). The two sets of rotating members 223 may be spaced apart, that is, the rotating members 223 on the same outer side of the bracket 221 of the two sets of rotating members 223 are spaced apart side by side.

The two side walls 2221b of each brush plate 2221 are respectively provided with a sliding hole 22211, which are respectively matched with the rotating members 223 located on the two outer side surfaces of the bracket 221. That is, the brush plate 2221 is substantially enclosed outside one end of the holder 221. The shape of the through slot 22210 may generally conform to the profile of the bracket 221. When the two brush plates 2221 are rotated about their corresponding rotating members 223 to be coupled to each other, the two brush plates 2221 are enclosed outside one end of the holder 221, that is, one end of the holder 221 is located in the channel 2220, and the two brush plates 2221 are also slid with respect to the holder 221, so that the length of the brush plate assembly 222 can be changed.

As shown in fig. 10, in the present embodiment, when the two brush plates 2221 are opened to a predetermined angle, the maximum value of the predetermined angle can be determined by the position relationship between the brush plates 2221 and the groove bottom wall surface 2213. The two brush plates 2221 rotate around the corresponding rotating member 223 to enter the opening 2214, and the opposite sides of the brush plates 2221 can abut against the edge of the opening 2214, so that the two brush plates 2221 can be limited to rotate continuously, and at this time, the preset included angle is the maximum value. For example, when the respective opposite sides of the two brush plates 2221 are opened to each other, the two brush plates 2221 form a predetermined included angle therebetween, which is greater than 0 ° and less than or equal to 200 °. Alternatively, the preset included angle may be greater than or equal to 185 °.

During use, a user can adjust the preset angle at which the two brush plates 2221 are opened to each other according to the actual cleaning environment to be cleaned. For example, for the ground, the preset included angle may be adjusted to make the brush plate 2221 substantially close to the ground, the preset included angle is, for example, 180 °, and compared to the suction manner of the "split forming channel 2220", this may increase the suction area and use a more spacious cleaning environment.

In order to make the structure of the brush plate 2221 and the holder 221 more stable and effective, there are various structures of the brush plate 2221 for the brush plate 2221 having the bottom wall 2221a and the side wall 2221b, and an exemplary structure is given below:

as shown in fig. 6 and 10, the brush plate 2221 may include a main body portion 22212 and a connection portion 22213 connected to one end of the main body portion 22212. That is, the main body portion 22212 and the connection portion 22213 are connected in order in the longitudinal direction of the brush plate 2221. The connection portion 22213 is for connection with the bracket 221. The main body 22212 and the connecting portion 22213 may be integrally formed, or may be a combined structure. The side wall 2221b may be divided into a side wall 2221b of the body portion 22212 and a side wall 2221b of the connection portion 22213, and the bottom wall 2221a may be divided into a bottom wall 2221a of the body portion 22212 and a bottom wall 2221a of the connection portion 22213.

The slide hole 22211 may be opened at a side wall 2221b of the connection portion 22213. One end of the body portion 22212 projects relative to the bottom wall 2221a of the connecting portion 22213 in a direction away from the opposite side to form a retaining edge 2221 c. As the brush plate 2221 is moved relative to the holder 221 toward the slot bottom wall 2213 by the sliding engagement of the rotator 223 and the slide hole 22211, the slot bottom wall 2213 can stop the stop to limit the rotator 223 to the first position of the slide hole 22211. Of course, the first position of the slide hole 22211 may be an end point of the slide hole 22211 close to the main body 22212, and the second position of the slide may be an end point of the slide hole 22211 far from the main body 22212. Alternatively, the shape of the stopping edge 2221c is adapted to the shape of the two side openings 2214 of the mounting slot 2211, so that when the rotating member 223 is located at the first position of the sliding hole 22211, the stopping edges 2221c of the two brush plates 2221 can be complementary to the two side openings 2214, so that the shape of the brush head 22 can exhibit strong integrity.

As shown in fig. 6, with respect to the brush plate 2221, the sectional area of the through slots 22210 of the connecting portion 22213 may be larger than the sectional area of the through slots 22210 of the main body portion 22212, in a plane perpendicular to the extending direction of the through slots 22210 as a sectional plane. The through slots 22210 of the connecting portions 22213 are portions of the through slots 22210 in the connecting portions 22213, and the through slots 22210 of the main body portion 22212 are portions of the through slots 22210 in the main body portion 22212. Alternatively, the passages 2220 of the two brush plates 2221 after the connection portions 22213 are coupled may surround the through-hole 2210, that is, the cross-sectional area of the portions of the passages 2220 at the connection portions 22213 is larger than the cross-sectional area of the through-hole 2210. The sectional area of the through groove 22210 of the connecting portion 22213 is larger than that of the through groove 22210 of the main body portion 22212, so that the sectional area of the passage 2220 at the connecting portion 22213 is larger than that of the passage 2220 at the main body portion 22212, the passage 2220 of the connecting portion 22213 has a certain buffering effect on high-speed airflow entering from the passage 2220 of the main body portion 22212, and the larger passage 2220 of the connecting portion 22213 ensures that the airflow enters the through hole 2210 more stably, thereby improving the stability of the operation of the dust collector 1.

When the dust suction device 1 faces some clean environments, brushing and then sucking are needed, and therefore a better cleaning effect can be achieved. As shown in fig. 6 and 11, the brush plate assembly 222 can include two bristle members 2222. The bristle part 2222 has bristles, and can be used to brush garbage, etc. Two bristle members 2222 are slidably disposed on opposite sides of the two brush plates 2221, respectively, facing away from the opposite side. Two bristle members 2222 and two brush plates 2221 may correspond one to one. The bristle part 2222 can slide on the brush plate 2221 along the extending direction of the through slot 22210, and when the bristle part 2222 slides to the end of the brush plate 2221 away from the support 221, the bristles of the bristle part 2222 can extend out of the end of the brush plate 2221 away from the support 221 (i.e., the bristles cross the end of the brush plate 2221 away from the support 221) to achieve the cleaning function. The dust suction apparatus 1 can suck while cleaning. In this embodiment, the bristle part 2222 can be used in conjunction with a "narrow mouth mode".

Alternatively, the bristle part 2222 may be slidably disposed on the opposite side of the body 22212 (i.e., the opposite side corresponds to the portion of the body 22212). As shown in fig. 6 and 11, opposite sides of the main body portion 22212 may be formed with lands 22212b along the extending direction of the through slots 22210. Specifically, a portion of the region adjacent to one end of the main body 22212 on the opposite side may be set as a plateau 22212a (the edge of the plateau 22212a contacting the connecting portion 22213 forms the above-mentioned blocking edge 2221c), the other region on the opposite side forms a platform 22212b, and the platform 22212b is lower than the plateau 22212a in the direction away from the opposite side (i.e., in the direction from the opposite side to the opposite side). The bristle members 2222 can be disposed on the platform 22212b and can slide on the platform 22212 b. The bristle members 2222 are slidable on the platform 22212b in the direction of extension of the through slots 22210. The plateau 22212a can be restricted from further movement toward the connecting portion 22213.

Alternatively, as shown in fig. 6 and 12, the side of the bristle part 2222 facing the platform 22212b may be provided with a slider 22221. The platform 22212b may be formed with a slide rail 2221d extending along the extending direction of the through slot 22210. The slider 22221 may be embedded in the slide rail 2221d, and may slide in the slide rail 2221 d. For example, the slider 22221 and the slide rail 2221d may have an inverted T-shape. The sliding rail 2221d may not penetrate through an end of the main body 22212 away from the connecting portion 22213 (i.e., an end of the brush plate 2221 away from the bracket 221), so that when the bristle holder 2222 moves to an end of the brush plate 2221 away from the bracket 221, the sliding block 22221 is restricted from further moving outward, and the bristles may correspondingly extend out of an end of the brush plate 2221 away from the bracket 221.

In order to stabilize the bristle part 2222 at the connection point with the plateau 22212a or at the end of the brush plate 2221 away from the support 221, the bristle part 2222 can be snap-fitted into the main body 22212 at the above two positions, so that it can be fixed with the main body 22212, and the stability of the bristle part in the working state or the non-working state can be ensured. Of course, the first magnetic element 224 may be disposed on the end of the platform 22212b adjacent to the plateau 22212a and the end of the platform 22212b away from the plateau 22212a, respectively, and the second magnetic element 225 is disposed on the bristle 2222, so that the first magnetic element 224 and the second magnetic element 225 can be attracted to each other, and further, the bristle 2222 can be stably located at the above two positions, and due to the magnetic effect, damping can be provided for the sliding of the bristle 2222, so that the sliding process thereof is more stable.
