Moreover, the first plug socket base 633 and the second plug socket base 634 have different shapes and structures, the respective cavities of the first plug socket cavity 853 and the second plug socket cavity 854 are respectively corresponding to the same shapes and structures of the first plug socket base 633 and the second plug socket base 634, and the two plug socket bases and the corresponding two plug socket cavities form an anti-reverse-plugging mechanism for the power input interface 63 and the power output interface 85, so that the anti-reverse-plugging function can be achieved.

In this embodiment, the pair of first terminals 631 and the pair of third terminals 851 serve as positive and negative terminals, and the second terminal 632 and the fourth terminal 852 serve as communication terminals. When the power input interface 63 is connected to the power output interface 85, the pair of first terminals 631 and the pair of third terminals 851 are correspondingly connected to form a current path, so that the energy storage module 83 supplies power to the driving member through the current path, and the second terminal 632 and the fourth terminal 852 are correspondingly connected to form an information path to transmit communication information.

Optionally, the communication information includes at least one of a real-time temperature value of the driving element, a real-time temperature value of the energy storage module 83, and a real-time current value of a circuit connecting the driving element and the energy storage module 83. The application provides an be equipped with at least one controller in dust catcher 1, the controller can acquire communication information is and based on communication information control driving piece and/or energy storage module 83's operating condition to protect driving piece and/or energy storage module 83 under some emergency situations.

After the second terminal 632 is correspondingly connected to the fourth terminal 852, the first controller and/or the second controller can obtain the communication information, and control the working state of the driving member and/or the energy storage module 83 based on the communication information. For example, in an embodiment, when the real-time temperature value of the driving element is too high, the first controller controls the driving element to stop working and/or the second controller controls the energy storage module 83 to stop supplying power to the driving element so as to stop working of the driving element, and further gradually decrease the temperature of the driving element, thereby preventing the driving element from being burned out due to too high temperature. In another embodiment, when the real-time temperature of the energy storage module 83 is too high, the second controller controls the energy storage module 83 to stop charging and discharging, so that the temperature of the energy storage module 83 is gradually reduced, and the energy storage module 83 is prevented from burning and even exploding due to too high temperature.

Referring to fig. 6, fig. 7, and fig. 11 to fig. 15, in the present embodiment, the outer shell of the first casing 61 includes an outer shell body 614 and a connecting seat 616 disposed in the inner cavity of the front end of the outer shell body 614, the outer shell body 614 and the connecting seat 616 are enclosed to form a receiving cavity (not shown), and the inner shell 612 is located in the receiving cavity.

As shown in fig. 11, the cavity of the inner housing 612 is used for mounting the functional assembly 65, and the connecting base 616 is provided with the second mounting structure 6163.

Specifically, as shown in fig. 11 to 15, in the present embodiment, the inner shell 612 includes an inner shell main body 6121 and an extension 6122 connected to the inner shell main body 6121. The inner casing main body 6121 is a cylindrical casing with an open front end and a closed rear end, and the extension 6122 is an approximately rectangular annular sheet body that is convexly disposed on the rear end casing of the inner casing main body 6121. The axis of the extension 6122 is parallel to the axis of the inner housing main body 6121 and is located at one side of the axis of the inner housing main body 6121, that is, the extension 6122 is eccentrically and convexly disposed on the rear end housing of the inner housing main body 6121. Obviously, in other embodiments, the axis of the extension 6122 may coincide with the axis of the inner housing body 6121.

As shown in fig. 5 and 13, the extension 6122 and the rear end housing of the inner housing 6121 together form an insertion slot with an open rear end, and the insertion slot constitutes the first connecting structure 62 disposed at the rear end of the first housing 61. As shown in fig. 5, the second connecting structure 84 of the power supply part 80 is a plug block disposed at the front end of the second housing 82, the plug block is adapted to the plug groove, and when the plug block is plugged into the plug groove, the power supply part 80 can be detachably connected to the main body part 60.

Preferably, in order to prevent the plug block from being reversely inserted into the plug slot, that is, to prevent the user from reversely inserting the power supply portion 80 into the rear end of the main body portion 60, at least one inner wall of the plug slot in the first direction (the up-down direction shown in fig. 5 and 13) is provided with a first guide structure 623, at least one outer wall of the plug block in the first direction is provided with a second guide structure 842 (see fig. 4) corresponding to the first guide structure 623, and the first guide structure 623 and the corresponding second guide structure 842 constitute a first reverse insertion prevention mechanism, so as to prevent the plug block from being reversely inserted into the plug slot. Specifically, as shown in fig. 5 and 13, in this embodiment, the inner walls of two opposite sides of the insertion slot in the first direction are respectively formed with a bar-shaped protrusion extending along the axial direction of the extension body 6122, where the bar-shaped protrusion is the first guiding structure 623; as shown in fig. 4, the outer walls of two opposite sides of the insertion block in the first direction are respectively provided with a bar-shaped groove corresponding to the bar-shaped protrusion, and the bar-shaped groove is the second guiding structure 842. The two strip-shaped convex blocks positioned on the inner walls of the two opposite sides of the insertion groove can be arranged into strip-shaped convex blocks with different thicknesses and/or different widths, and can also be asymmetrically arranged on the inner walls of the two opposite sides of the insertion groove, so that each strip-shaped convex block can only be inserted into the corresponding strip-shaped insertion groove. Therefore, when the inserting block is inserted into the inserting groove, if the strip-shaped convex block is not aligned with the corresponding strip-shaped groove, the inserting block cannot be completely inserted into the inserting groove, so that the effect of preventing reverse insertion is achieved; moreover, the inserting block is inserted into the inserting groove, the strip-shaped convex block is gradually inserted into the corresponding strip-shaped groove, shaking in the inserting process can be avoided, and inserting stability is improved.

In other embodiments, when the wall thickness of the extension body 6122 is thicker, the first guiding structure 623 may also be a strip-shaped groove disposed on the inner wall thereof, and correspondingly, the second guiding structure 842 is a strip-shaped protrusion disposed on the outer wall of the insertion block, and can also play a role in preventing reverse insertion and shaking.

The shape of the axial section of the strip-shaped convex block comprises but is not limited to a rectangle, a semicircle, a triangle and the like, and the groove shape of the strip-shaped groove corresponds to the axial section shape of the strip-shaped convex block.

Further preferably, as shown in fig. 4 and 5, in this embodiment, opposite sides of the slot of the insertion groove in a second direction (a left-right direction shown in fig. 4 and 5) perpendicular to the first direction respectively include a first shape structure and a second shape structure, the first shape structure and the second shape structure are different, the shape structures of opposite sides of the front end of the insertion block in the second direction are respectively matched with the shape structure of one side corresponding to the slot, and the slot of the insertion groove and the front end of the insertion block form a second anti-reverse insertion mechanism, which also can prevent reverse insertion. Specifically, as shown in fig. 4 and 5, in the present embodiment, the first shape structure and the second shape structure are a half-square structure and a half-circular structure, respectively. It can be understood that, when the insertion block is inserted into the insertion groove, if the shape structures of the two opposite sides of the end of the insertion block do not correspond to the shape structures of the two opposite sides of the slot opening of the insertion groove, the insertion block cannot be inserted into the insertion groove, so that the anti-reverse insertion function can be achieved. In this embodiment, under the dual guarantee of the first anti-reverse-insertion mechanism and the second anti-reverse-insertion mechanism, the user can be effectively prevented from reversely inserting the plug block into the plug slot, so as to ensure the correct connection between the power supply part 80 and the main body part 60.

In this embodiment, the corresponding structures included in the first reverse insertion prevention mechanism are respectively disposed on two opposite sides of the insertion slot and the insertion block in the first direction, the corresponding structures included in the second reverse insertion prevention mechanism are respectively disposed on two opposite sides of the insertion slot and the insertion block in the second direction, and the first direction is perpendicular to the second direction. It can be understood that, in other implementations, corresponding structures included in the first anti-reverse-insertion mechanism and the second anti-reverse-insertion mechanism may also be disposed on opposite sides of the insertion slot and the insertion block in the first direction or the second direction, and a double anti-reverse-insertion function may also be implemented, which is not described herein.

Referring to fig. 3 to fig. 5 and fig. 8 again, as mentioned above, the second connecting structure 84 (i.e. the plugging block) at the front end of the second housing 82 is matched with the first connecting structure 62 (i.e. the plugging slot) at the rear end of the first housing 61, so that the power portion 80 is detachably connected to the main body portion 60.

Specifically, as shown in fig. 8, in the present embodiment, the second housing 82 is formed by an upper housing 821 and a lower housing 823 which are mutually combined by a threaded connection or a snap connection, each of the upper housing 821 and the lower housing 823 includes a main body portion and an insertion portion which is connected to a front end of the main body portion and has a size smaller than that of the main body portion, the main body portion and an inner side of the insertion portion (i.e., a side close to an axis of the second housing 82) are flush, and a stop step located on the outer side is formed at a connection position of the insertion portion and the main body portion.

The front end and the rear end of the plug-in part of the lower shell 823 are respectively provided with a first end plate and a second end plate, and the first end plate and the second end plate respectively exceed the inner sides of the main body part and the plug-in part of the lower shell 823. As shown in fig. 3, when the upper housing 821 and the lower housing 823 are mutually mated, the main body portion and the insertion portion of each of the upper housing 821 and the lower housing 823 are respectively and correspondingly connected, the first end plate and the second end plate are respectively packaged at the front end and the rear end of the correspondingly connected upper housing 821 and lower housing 823, and the insertion portion and the first end plate of each of the upper housing 821 and the lower housing 823 constitute the second connection structure 84 (i.e., the aforementioned insertion block) at the front end of the second housing 82. As shown in fig. 8, a first accommodating cavity is formed between the main body parts of the upper housing 821 and the lower housing 823, and the first accommodating cavity is used for fixedly arranging the energy storage module 83; a second accommodating cavity is formed between the respective plugging portions of the upper housing 821 and the lower housing 823, the second accommodating cavity is used for fixedly arranging the power output interface 85 and the battery protection board 86, and the first end board is provided with a through hole exposed out of the third plugging seat body of the power output interface 85. The power output interface 85 and the battery protection board 86 are electrically connected to the energy storage module 83 through wires or connectors, respectively. Therefore, when the power portion 80 is connected to the main body portion 60 by the second connection structure 84 and the first connection structure 62 (i.e. the insertion groove) in an insertion fit manner, the power output interface 85 exposed out of the first end plate can be correspondingly connected to the power input interface 63 exposed out of the bottom of the insertion groove, so that the energy storage module 83 can supply power to the driving member in the main body portion 60.

It should be noted that, in this embodiment, when the plug-in block (i.e., the second connecting structure 84) is plugged into the plug-in groove (i.e., the first connecting structure 62), the notch portion of the plug-in groove abuts against a portion of the second housing 82 adjacent to the rear end of the plug-in block, that is, abuts against the stopping step formed between the main portion and the plug-in portion of each of the upper housing 821 and the lower housing 823. Through the arrangement of the stop step structure, the depth of the insertion block inserted into the insertion groove can be limited, the power input interface 63 and the power output interface 85 which are used for electric connection are prevented from being damaged due to the fact that a user exerts too much force, abrasion of products is reduced, the service life of the products is prolonged, and use safety is improved.

Preferably, as shown in fig. 5, 8 and 13, in this embodiment, a first locking structure 621 is disposed on an inner wall of the slot of the insertion slot, and a second locking structure 8252 is disposed on a portion of the second housing 82 adjacent to the rear end of the insertion block, corresponding to the first locking structure 621. When the plug block is plugged into the plug groove, the notch of the plug groove abuts against the part of the second shell 82, which is adjacent to the rear end of the plug block, and the first locking structure 621 is matched with the second locking structure 8252 to limit the power supply part 80 to move relative to the main body part 60, so that the reliability and stability of connection between the power supply part 80 and the main body part 60 are ensured, and the energy storage module 83 is further ensured to stably supply power to the driving part.

As shown in fig. 13, in this embodiment, the first locking structure 621 is a pair of clamping grooves formed on an inner wall of a front end opening of the small-diameter section 6142 of the housing body 614, and the pair of clamping grooves are located on two opposite sides of the inner wall of the front end opening of the small-diameter section 6142 in the first direction; as shown in fig. 8, in the embodiment, the upper housing 821 and the lower housing 823 are respectively provided with a spring plate 825, the spring plate 825 is disposed at the front end of the main body portion of each of the upper housing 821 and the lower housing 823, the front end of each spring plate 825 exceeds the main body portion and faces the rear end of the inserting portion, and the front end of each spring plate 825 is provided with a hook-shaped hook, which is the second locking structure 8252.

When the power supply part 80 is connected with the main body part 60, a user presses the elastic sheet 825 to make the elastic sheet 825 elastically deform so as to drive the second locking structure 8252 (namely, the hook-shaped hook) to move close to the axis of the second housing 82 and tilt, so that the insertion of the insertion block into the insertion slot is not hindered until the notch part of the insertion slot abuts against the second housing 82 and is adjacent to the stop step, at this time, the second locking structure 8252 of the elastic sheet 825 just faces the first locking structure 621 (namely, the slot) on the inner wall of the insertion slot, the pressing of the elastic sheet 825 is released, and the second locking structure 8252 is clamped into the first locking structure 621 along with the resilience of the elastic sheet 825, so that the connection between the power supply part 80 and the main body part 60 is realized, the relative movement between the power supply part 80 and the main body part 60 is limited, and the reliability and the stability of the connection between the power supply part 80 and the main body part 60 are ensured. When the connection between the power supply unit 80 and the main body unit 60 needs to be released, the plug block can be directly pulled out from the plug slot by pressing the elastic sheet 825 to disengage the second locking structure 8252 from the first locking structure 621, so that the power supply unit 80 is separated from the main body unit 60.

Further, referring to fig. 3 and fig. 8, optionally, in the present embodiment, the power portion 80 is not provided with a power connection line, the second housing 82 is further provided with a charging interface 87, and the charging interface 87 is used for externally connecting an adaptive power supply to charge the energy storage module 83 and/or a load device electrically connected to the energy storage module 83. After the power supply portion 80 is disconnected from the main body portion 60, the user can charge the energy storage module 83 and the load device electrically connected to the energy storage module 83 through the charging interface 87, so that the energy storage module 83 can be recycled, the user does not need to carry a plurality of standby power supplies, and the load of the user is reduced.

The charging interface 87 includes but is not limited to a Type-C interface, a Type-a interface, and the like. In this embodiment, the Type-C interface is preferably selected as the charging interface 87, so that the energy storage module 83 can be charged through the charging interface 87, and can also be used as a mobile charger to charge electronic devices such as mobile phones through the charging interface 87.

As shown in fig. 3 and 8, in the present embodiment, the charging interface 87 is mounted on the first end plate of the second housing 82 and electrically connected to the battery protection plate 86. When the energy storage module 83 is charged through the charging interface 87, the battery protection plate 86 can protect the energy storage module 83, and the problem of overcharging is prevented. It is understood that in other embodiments, charging interface 87 may be disposed at other positions of second housing 82, such as on the second end plate of second housing 82, or on the main body portion of upper housing 821 or lower housing 823, which is not limited thereto.

Optionally, in this embodiment, the power supply portion 80 may also be provided with a power connection line penetrating through the second housing 82, and the power connection line is used for externally connecting an adaptive power supply to charge the energy storage module 83 and/or a load device electrically connected to the energy storage module 83, which is not described herein again.

As shown in fig. 3 and 8, in the present embodiment, the power supply portion 80 further includes an electric quantity display device 88 disposed on the second housing 82, and the electric quantity display device 88 is electrically connected to the energy storage module 83 for displaying the electric quantity of the energy storage module 83. Specifically, as shown in fig. 3 and 8, the electric quantity display device 88 is disposed on the upper housing 821, and the electric quantity display device 88 includes an electric quantity display key and a plurality of display lamps electrically connected to the electric quantity display key, and the display lamps are used for displaying the electric quantity of the energy storage module 83. When the user presses the electric quantity display key, if the energy storage module 83 has electric quantity, at least one of the display lamps emits light, and the number of the display lamps emitting light is in direct proportion to the electric quantity of the energy storage module 83. The user is luminous through observing whether the electric quantity that the energy storage module 83 just can be judged to the quantity of display lamp is sufficient, and is directly perceived convenient, easily observes.

In other embodiments, the power display device 88 may also be disposed in the lower casing 823, or in both the upper casing 821 and the lower casing 823, or in other positions of the second casing 82, as long as the power display key and the display lamp can be exposed outside the second casing 82, which is not limited thereto.

Referring to fig. 1 and fig. 2 again, in the present embodiment, at least a portion of the surface of the second housing 82 is provided with a handheld structure (not shown), which surrounds at least a portion of the energy storage module 83 located in the second housing 82, so that a user can insert and extract the power supply portion 80 by holding the second housing 82. The handheld structure comprises an anti-slip structure and/or a holding structure conforming to the holding shape of a human hand. The second housing 82 of the power supply part 80 serves as a handle, so that the dust collector 1 can be conveniently held by a user for use, and the dust collector 1 does not need to be additionally provided with the handle, so that the overall size and weight of the dust collector 1 are reduced, and the dust collector is convenient to store and carry.

As shown in fig. 1 and 2, in the present embodiment, the axial direction of the portion of the second housing 82 provided with the handheld structure is parallel to the axial direction of the main body portion 60, so that the entire cleaner 1 is in a straight shape. It can be understood that, in other embodiments, the axial direction of the portion of the second housing 82 provided with the handheld structure may also be inclined with the axial direction of the main body portion 60, so that the power portion 80 forms a certain included angle with the main body portion 60, preferably inclines towards the bottom side direction of the aforementioned first direction, and is more convenient for a user to hold with respect to the power portion 80 inclined downwards of the main body portion 60, and when the user uses the vacuum cleaner 1, the comfort level of the human body is high, and the dust at each corner can be sucked out with a small bending angle.

Referring to fig. 1 and 19 together, in the preferred embodiment, the vacuum cleaner 1 further includes a plug assembly, so that the vacuum cleaner 1 can be used to remove sticky stains.

Specifically, as shown in fig. 1 and 19, the plug assembly includes a first pipe body disposed on the vacuum cleaner 1 and a first plug member 91 slidably sleeved outside the first pipe body. In this embodiment, the first tube body is a dust suction tube 214, and an end of the dust suction tube 214 having the dust suction opening 2143 (i.e., a front end of the dust suction tube 214) is defined as a first working end. In order to distinguish from a dust suction port of a third connector described later, the dust suction port 2143 is defined as a first dust suction port 2143, and the dust suction port of the third connector is defined as a second dust suction port.

As shown in fig. 1 and 19, in the present embodiment, the first connector 91 includes a brush slidably sleeved outside the dust suction pipe 214, the brush includes a sleeve 912 sleeved outside the dust suction pipe 214 and bristles 914 disposed at an end of the sleeve 912 close to the first dust suction port 2143, and an end of the bristles 914 far away from the sleeve 912 (i.e., an end close to the first working end) defines a second working end.

As shown in fig. 16, in the present embodiment, the outer wall of the dust suction pipe 214 (i.e., the first pipe body) is provided with a first limiting structure 2141 and a second limiting structure 2142 which are distributed at intervals along the axial direction thereof, the first limiting structure 2141 is located at a side of the second limiting structure 2142 away from the first working end, that is, the first limiting structure 2141 is farther from the first dust suction opening 2143 than the second limiting structure 2142; the housing 912 of the first connector 91 (i.e., the brush) has a third position-limiting structure 9123, and the third position-limiting structure 9123 is used to be correspondingly engaged with the first position-limiting structure 2141 or the second position-limiting structure 2142.

Optionally, the first limiting structure 2141 and the second limiting structure 2142 are limiting blocks protruding from the outer wall of the dust collecting tube 214, and the third limiting structure 9123 is a limiting groove formed in the casing 912; or, the first limiting structure 2141 and the second limiting structure 2142 are limiting grooves formed in the outer wall of the dust collecting tube 214, and the third limiting structure 9123 is a limiting block protruding from the inner wall of the housing 912. In this embodiment, the first limiting structure 2141 and the second limiting structure 2142 are limiting blocks, and the third limiting structure 9123 is a limiting groove.

As shown in fig. 1, when the brush is far from the first working end along the axial direction of the dust collection pipe 214 and slides to the third limiting structure 9123 to be matched with the first limiting structure 2141, the brush is located at the first position, the end of the first working end is exposed out of the brush, the dust collector 1 realizes a first function through the first dust collection port 2143 of the first working end, and the first function is a dust collection function, that is, the dust collector 1 can realize a dust collection function through the first dust collection port 2143. As shown in fig. 19, when the brush is axially close to the first working end along the dust collection pipe 214 and slides to the third limiting structure 9123 to match with the second limiting structure 2142, the brush is located at the second position, the first working end is located in the brush, the dust collector 1 realizes the second function through the bristles 914 at the second working end, and the second function is a sweeping function, that is, the dust collector 1 can realize the sweeping function through the bristles 914.

Therefore, when a user needs to use the vacuum cleaner 1 to remove sticky and solidified stains, the brush can be slid to the second position, the sticky and solidified stains are loosened through the brushing function of the bristles 914, then the brush is slid to the first position, and the loosened stains are sucked into the dust collecting portion 40 through the dust collecting function of the first dust collecting opening 2143, so that the sticky and solidified stains can be removed.

In the dust collector 1 provided by the embodiment, the slidable brush is sleeved outside the dust collection pipe 214, and the brush can slide to different positions as required, so that the dust collector 1 is utilized to realize a sweeping function or a dust collection function, and the problem that the existing dust collector cannot remove the sticky and solidified stains due to limited suction can be solved. Moreover, compared with the prior art that the dust collector needs to be additionally provided with an independent brush, the brush sleeved outside the dust collection pipe 214 in a sliding manner can be stored together with the dust collector 1, no additional storage space needs to be occupied, and the brush does not need to be found in time.

Referring again to fig. 16 and 17, alternatively, the axial cross-sections of the suction pipe 214 and the casing 912 may be oblate or elliptical, i.e., the suction pipe 214 and the casing 912 are respectively oblate tube and casing, or respectively elliptical tube and casing. In this embodiment, the suction tube 214 and the housing 912 are an oblate tube and a housing, respectively.

Defining the oblate or elliptical minor axis direction as a first reference direction, optionally, the first and second limiting structures 2141 and 2142 are disposed on at least one side of an outer wall of the dust suction pipe 214 in the first reference direction, and the third limiting structure 9123 is correspondingly disposed on at least one side of an inner wall of the housing 912 in the first reference direction.

Specifically, as shown in fig. 16 and 17, in this embodiment, the outer wall of one side of the dust suction pipe 214 in the first reference direction is provided with a first limiting structure 2141 and a second limiting structure 2142, the inner wall of the corresponding side of the case 912 in the first reference direction is provided with a third limiting structure 9123, and the structures of the dust suction pipe 214 and the case 912 are simple.

In other embodiments, the outer wall of each side of the dust suction pipe 214 in the first reference direction may be provided with a first limiting structure 2141 and a second limiting structure 2142, and the inner walls of the two opposite sides of the housing 912 in the first reference direction are respectively and correspondingly provided with a third limiting structure 9123, or the outer wall of one side of the dust suction pipe 214 in the first reference direction is provided with a first limiting structure 2141, the outer wall of the other side of the dust suction pipe is provided with a second limiting structure 2142, and the two opposite sides of the housing 912 in the first reference direction are respectively and correspondingly provided with a third limiting structure 9123, which is not limited. The dust suction pipe 214 and the sleeve 912 can enhance the limiting effect of the brush when the brush slides to different positions on the dust suction pipe 214 by arranging corresponding limiting structures on two opposite sides of the first reference direction.

It should be noted that when the brush is located at the first position (see fig. 1), an axial distance between an end of the first working end (i.e., an end of the dust suction pipe 214 at which the first dust suction opening 2143 is disposed) and an end of the second working end (i.e., an end of the bristle 914 at which the bristle 914 is away from the casing 912) is defined as a first distance, and an axial distance between the first limiting structure 2141 and the second limiting structure 2142 is defined as a second distance, in this embodiment, the first distance is greater than or equal to zero, and the second distance is greater than the first distance. By defining the second distance to be greater than the first distance, it is ensured that the end of the bristles 914 remote from the casing 912 can extend beyond the end of the suction tube 214 at which the first suction opening 2143 is provided, when the brush is slid from the first position to the second position, thereby ensuring that the bristles 914 at the second working end can be used for sweeping solidified dirt. Similarly, the second distance is defined to be greater than the first distance, so as to ensure that the end of the dust collection pipe 214 where the first dust collection opening 2143 is arranged can be exposed from the end of the brush hair 914 far away from the casing 912 when the brush slides from the second position to the first position, thereby ensuring that the first dust collection opening 2143 of the first working end can be used for collecting dust.

In this embodiment, preferably, the outer wall of the sleeve 912 may be provided with an anti-slip structure, so that a user can conveniently hold the sleeve 912 to drive the brush to slide on the dust suction pipe 214.

Preferably, as shown in fig. 1 and 19, in this embodiment, a plane where the end of the first working end is located is defined as a first plane, a plane where the end of the second working end is located is defined as a second plane, and both the first plane and the second plane are inclined with respect to the axis of the dust suction pipe 214, that is, both the first plane and the second plane are inclined planes which are obliquely intersected with the axis of the dust suction pipe 214. It can be understood that when the user holds the cleaner 1 for use, the axis of the cleaner 1 is generally inclined, and the first plane and the second plane are set as inclined planes which obliquely intersect with the axis of the dust suction pipe 214, compared with the case that the first plane and the second plane are both perpendicular to the axis of the dust suction pipe 214, the contact area between the end of the first working end and the end of the second working end and the cleaning surface can be increased, which is beneficial to improving the dust suction efficiency.

Further, referring to fig. 1 and fig. 20 to fig. 22, in the present embodiment, the plugging assembly 90 further includes an extension tube 93 and a second plugging member 95 connected to one end of the extension tube 93, the second plugging member 95 is a floor mopping member, and the floor mopping member includes an adapter 952 connected to one end of the extension tube 93, a floor mopping member body 954 rotatably connected to the adapter 952, and a flexible connecting tube 956 disposed in the adapter 952.

The adaptor 952 further includes an adaptor tube 9521 disposed in the adaptor body 9522 and a plug tube 9523 connected to an end of the adaptor body 9522 remote from the adaptor tab 9524, wherein the adaptor tube 9521 is in communication with an inner cavity of the plug tube 9523. The plug-in pipe 9523 is adapted to be plugged into an end of the extension pipe 93 away from the dust suction pipe 214, the adaptor pipe 9521 is connected to an end of the flexible connecting pipe 956, the other end of the flexible connecting pipe 956 is connected to a dust suction cavity 9541 (see fig. 21) of the floor mopping body 954, and an end of the floor mopping body 954 provided with the dust suction cavity 9541 is defined as a third working end. It should be noted that the floor-mopping piece 95 further includes other structures such as rollers, and the specific structure thereof is substantially the same as that of a common floor-mopping piece of a vacuum cleaner, which is not described herein again.

As shown in fig. 19 and 20, in the present embodiment, when the first connector 91 (i.e., the brush) is located at the first position, the end of the extension tube 93 away from the second connector 95 is inserted into the first working end (i.e., the end of the dust suction tube 214 having the first dust suction opening 2143), so that the dust suction cavity 9541 of the floor mopping body 954 is communicated with the first dust suction opening 2143 of the dust suction tube 214 through the flexible connecting tube 956, the adapter tube 9521, the insertion tube 9523 and the extension tube 93, and thus the dust suction function of the dust collector 1 can be achieved through the third working end. The user need not bow to press the dust suction pipe 214 close to the bottom surface, and can directly realize the cleaning of the ground through the extension pipe 93 inserted in the dust suction pipe 214 and the floor mopping piece 95 connected with the extension pipe 93, thereby reducing the burden of the user.

As shown in fig. 19 and 20, in this embodiment, the extension tube 93 includes a plurality of second tube bodies with equal diameters and connected to each other in an inserting manner, the front end (i.e., the first working end) of the dust collection tube 214 and the front end of each of the second tube bodies are respectively provided with a first inserting structure, the rear end of each of the second tube bodies and the rear end of the inserting tube body 9523 of the adaptor 952 are respectively provided with a second inserting structure, and each adjacent two tube bodies of the dust collection tube 214, the plurality of second tube bodies and the inserting tube body 9523 are detachably connected by the corresponding inserting and connecting of the first inserting structure and the second inserting structure.

It is understood that the length of the extension tube 93 is proportional to the number of the second tubes, and the number of the second tubes may be one, two or other reasonable number, which is not limited herein.

In other embodiments, the extension pipe 93 may also include a plurality of third pipe bodies with gradually changing diameters and sleeved with each other, where the gradually changing diameters mean that the diameters of the plurality of third pipe bodies may be sequentially increased or sequentially decreased, as long as adjacent pipe bodies can be sleeved together, and details thereof are not described herein. It will be understood that the length of the extension tube 93 is also proportional to the number of said third tubes, which may be one, two or other reasonable number, without limitation.

In other embodiments, the extension tube 93 may also include a fourth tube with a flexible fold, the fourth tube comprising a flexible tube or a rigid tube, and the length of the extension tube 93 may also be changed as desired by stretching the fold of the fourth tube.

Preferably, as shown in fig. 22, in the present embodiment, the shape of the axial cross section of the adapter tube 9521 includes an oblate or oval shape, that is, the adapter tube 9521 is an oblate or oval tube. In the existing vacuum cleaner, the connecting portion of the hose and the adapter tube is a generally circular cavity, and in this embodiment, the adapter tube 9521 is set as an oblate tube or an oval tube, so that the connecting portion of the hose 956 and the adapter tube 9521 is an oblate cavity or an oval cavity, and compared with the circular cavity, the axial cross-sectional area of the oblate cavity or the oval cavity is smaller, and when the sizes of the whirling airflows formed by the functional components 65 of the vacuum cleaner 1 are the same, the smaller the cavity area of the connecting portion of the hose 956 and the adapter tube 9521 is, the larger the generated suction force is, which is beneficial to ensuring that the vacuum cleaner 1 still has sufficient suction force even after being inserted with the extension tube 93, and ensuring the dust collection effect of the mopping piece 95.

Further, in this embodiment, the plug-in component 90 further includes at least one third plug connector, the third plug connector is a plug-in dust collection head, one end of the plug-in dust collection head is used for the plug-in dust collection pipe 214, the other end of the plug-in dust collection head is equipped with a second dust collection port, the plug-in dust collection head is equipped with the one end definition of the second dust collection port is a fourth working end. Therefore, when the brush is located at the first position and the dust pipe 214 is not connected with the extension pipe 93 and the floor-mopping piece 95, one end of at least one inserted dust collection head is inserted at the front end of the dust pipe 214, and the dust collector 1 can realize a dust collection function through the fourth working end of the inserted dust collection head.
