As shown in fig. 1 and 2, a vacuum cleaner 100 according to an embodiment of the present invention includes a vacuum cleaner housing 20 and a floor brush assembly 40 installed in the vacuum cleaner housing 20, wherein the floor brush assembly 40 is used for collecting dust on a cleaning surface.

As shown in fig. 2 and 3, the cleaner housing 20 includes a fixed housing 21, a movable housing 23, and a locking knob assembly 25. The movable housing 23 is detachably coupled to the fixed housing 21, one end of the locking knob assembly 25 is fixedly connected to the movable housing 23 and the fixed housing 21, and the other end of the locking knob assembly extends out of the fixed housing 21 for being held by a user. When the movable housing 23 is coupled to the fixed housing 21, the movable housing 23 and the fixed housing 21 together form a receiving cavity for mounting the floor brush assembly 40. When the movable housing 23 and the stationary housing 21 are separated from each other, the user can replace or clean the floor brush assembly 40. It should be noted that, since the floor brush assembly 40 is not a main improvement point of the present invention, the specific structure of the floor brush assembly 40 is not described herein.

Specifically, the fixed housing 21 is provided with a second limiting portion, the movable housing 23 is provided with a first limiting portion 232, and when the movable housing 23 and the fixed housing 21 are coupled to each other, the first limiting portion 232 and the second limiting portion are sequentially arranged in the first direction. The locking knob assembly 25 includes a first locking structure 252 coupled to the first position-limiting portion 232 and a second locking structure 254 coupled to the second position-limiting portion, and the locking knob assembly 25 can rotate around the first direction relative to the fixed housing 21 to switch between an unlocked state and a locked state.

When the locking knob assembly 25 is in the locked state, the first locking structure 252 is limited at the first limiting portion 232 in the first direction, the first locking structure 252 is limited at the second limiting portion in the direction rotating around the first direction, and the movable housing 23 is fixedly connected to the fixed housing 21.

Thus, the vacuum cleaner housing 20 can change the connection state of the locking knob assembly 25 relative to the fixed housing 21 and the movable housing 23 in the axial direction and the circumferential direction by easily holding the locking knob assembly 25 and rotating the locking knob assembly 25 to a certain angle in the first direction, thereby realizing the rapid switching of the locking knob assembly 25 between the locking state and the unlocking state, and therefore enabling the movable housing 23 to be rapidly connected or separated with the fixed housing 21, and therefore, a user can conveniently disassemble and assemble the movable housing 23 to replace or clean the floor brush assembly 40, thereby bringing great convenience to the use of the vacuum cleaner 100. Particularly, when the locking knob assembly 25 is in the locked state, the second locking structure 254 is restricted at the second restricting portion in a direction around the first direction, thereby preventing the first locking structure 252 from being released due to vibration of the cleaner 100.

The first direction mentioned above is a direction perpendicular to a plane when the cleaner 100 cleans the plane.

Referring to fig. 3 and 4, in addition to the first and second locking structures 252 and 254, the locking knob assembly 25 further includes a locking knob cover 256 and a connecting member 258. The first locking structure 252 and the second locking structure 254 are integrally formed, and the locking knob cover 256 is connected to the second locking structure 254 through a connecting member 258 and protrudes out of the movable housing 23. In this manner, the user can rotate the locking knob cover 256 to rotate the first locking structure 252 and the second locking structure 254 synchronously, thereby switching the locking knob assembly 25 between the unlocked state and the locked state.

The first locking structure 252 includes an axial connection post 2521 and an axial lock 2523. Specifically, the axial connection column 2521 is cylindrical, one end of the axial connection column 2521 is connected to the second locking structure 254, and the other end of the axial connection column 2521 is provided with two axial locking portions 2523. The two axial locking portions 2523 are oppositely arranged in the radial direction of the axial connection column 2521, each axial locking portion 2523 is cylindrical, one end of each axial locking portion 2523 is connected to the axial connection column 2521, and the other end of each axial locking portion 2523 extends in the radial direction of the axial connection column 2521 so as to be coupled to the first limiting portion 232 of the movable housing 23.

The second locking structure 254 includes a circumferential locking body 253 and a circumferential locking portion 255. Specifically, circumferential locking main body 253 includes first locking section 2532 and second locking section 2534, and first locking section 2532 is roughly cylindricly, and two slots of dodging that set up in the footpath relative are seted up to the lateral wall of first locking section 2532, and two dead slots that communicate two slots of dodging respectively are also seted up to one side terminal surface that second locking section 2534 is connected to first locking section 2532. Due to the opening of the avoiding groove and the empty groove, two hanging connecting arms 2532a are formed on the circumferential locking body 253 and are opposite to each other in the radial direction. Two circumferential locking portions 255 are provided to the two connecting arms 2532a, respectively, in the radial direction of the circumferential locking body 253. The second locking section 2534 extends axially from the end surface of one side of the first locking section 2532, two ribs 2534a extending axially are convexly arranged on the side wall of the second locking section 2534, the ribs 2534a are used for being matched with the locking knob cover 256, a connecting hole 2534b is further formed in the end surface of one side, away from the first locking section 2532, of the second locking section 2534, and the connecting hole 2534b is used for being connected with the connecting piece 258.

The locking knob cover 256 is provided with a fixing hole 2561, one end of the fixing hole 2561 is matched with the shape of the second locking section 2534, and the other end of the fixing hole 2561 is matched with the shape of the connecting piece 258. The connecting member 258 is a screw. Thus, the locking knob cover 256 is disposed at an end of the second locking section 2534 away from the first locking section 2532, and the connecting member 258 passes through the fixing hole 2561 and extends into the connecting hole 2534b of the second locking section 2534 and is threadedly connected to the connecting hole 2534b, so that the locking knob cover 256 is fixedly connected to an end of the second locking structure 254. Thus, the user can easily grip and rotate the locking knob cover 256, thereby rotating the second locking structure 254 and the first locking structure 252 in a first direction.

As shown in fig. 3, 5 and 6, the first limiting portion 232 is convexly disposed on the inner wall of the movable housing 23, an axial limiting hole 2321 is formed through the first limiting portion 232 along the first direction, and a cross section of the axial limiting hole 2321 perpendicular to the first direction is slightly larger than a cross section of the axial locking portion 2523, so as to allow the axial locking portion 2523 to pass through the axial limiting hole 2321.

Thus, when the locking knob assembly 25 is in the locked state, the first locking structure 252 is disposed through the axial limiting hole 2321, and the axial locking portion 2523 can abut against one side end surface of the first limiting portion 232 in the first direction. When the locking knob assembly 25 is in the unlocked state, the first locking structure 252 may pass through the axial restraint hole 2321 in a first direction to disengage the first restraint portion 232.

In some embodiments, an axial limiting groove 2323 having a bottom wall is formed on an end surface of the axial locking portion 2523 abutting against the first locking structure 252. When the locking knob assembly 25 is in the locked state, the axial locking portion 2523 passing through the axial limiting hole 2321 may be limited in the axial limiting groove 2323, thereby effectively preventing the axial locking portion 2523 from rotating in the first direction when in the locked state.

Further, the end surface of the first position-limiting portion 232 not provided with the axial position-limiting groove 2323 and the axial position-limiting hole 2321 extends obliquely from the center to the periphery, so that the thickness of the first position-limiting portion 232 is gradually reduced from the center to the edge. Therefore, when the axial lock portions 2523 are rotated relative to the first stopper portion 232, only a part of the axial lock portions 2523 are in contact with the end surface of the first stopper portion 232, thereby reducing the rotational resistance of the axial lock portions 2523.

As shown in fig. 3, 7 and 8, the second position-limiting portion located on the fixed housing 21 includes a circular circumferential position-limiting hole 212, a central axis of the circumferential position-limiting hole 212 extends along the first direction, a circumferential position-limiting groove 2121 is formed on a hole wall of the circumferential position-limiting hole 212, and the second locking structure 254 can be inserted into the circumferential position-limiting hole 212.

When the locking knob assembly 25 is in the unlocked state and the locked state, because the connecting arm 2532a is suspended, the circumferential locking body 253 deforms to a certain extent in the radial direction perpendicular to the second direction under the pressure action of the hole wall of the circumferential limiting hole 212, so that the circumferential locking portion 255 abuts against the hole wall of the circumferential limiting hole 212, which is not provided with the circumferential limiting groove 2121. When the locking knob assembly 25 is in the unlocked state or the locked state, the circumferential locking portion 255 may be retained in the circumferential retaining groove 2121, so that the second locking structure 254 is restricted from rotating around the first direction in the locked state, and at the same time, the pressure exerted on the circumferential locking body 253 by the hole wall of the circumferential retaining hole 212 is mostly or completely removed, and the circumferential locking body 253 returns to the original state, so that the circumferential locking portion 255 is difficult to be removed from the circumferential retaining groove 2121 without rotating by an external force.

In this way, since the circumferential locking portion 255 is retained in the circumferential retaining groove 2121, the locking knob assembly 25 cannot rotate in the first direction without applying an external force by a user, and thus, the axial locking portion 2523 is prevented from being automatically rotated to a position corresponding to the axial retaining hole 2321 and being removed from the axial retaining hole 2321 due to vibration during the operation of the vacuum cleaner 100.

Specifically, in some embodiments, the hole wall of the circumferential limiting hole 212 is provided with four circumferential limiting grooves 2121 arranged at equal intervals along the circumferential direction, and an included angle between a central point of each circumferential limiting groove 2121 and a connecting line of the centers of the circumferential limiting holes 212 is 90 °. In this way, when the locking knob assembly 25 is in the unlocked state or the locked state, the two circumferential locking portions 255 are respectively engaged in the two circumferential retaining grooves 2121 that are provided at intervals. The locking knob assembly 25 is rotatable by 90 ° in the counterclockwise direction or the clockwise direction about the first direction with respect to the stationary housing 21 to switch between the unlocked state and the locked state.

As shown in fig. 2 and 3, in some embodiments, the cleaner housing 20 further includes an elastic member 27, one end of the elastic member 27 is connected to the fixed housing 21, and the other end is connected to the movable housing 23, and when the movable housing 23 is coupled to the fixed housing 21, the elastic member 27 is in a compressed state. In this way, when the locking knob assembly 25 is in the unlocked state, the elastic member 27 is restored to the original state, thereby bringing the movable housing 23 to be automatically separated from the fixed housing 21.

The locking process of the locking knob assembly 25 described above is as follows:

first, the locking knob cover 256 is grasped, and the first locking structure 252 of the locking knob assembly 25 is inserted through the axial restraint aperture 2321, with the circumferential locking portion 255 also being snapped into the circumferential restraint slot 2121. Then, the locking knob cover 256 is rotated 90 ° clockwise or counterclockwise, the connecting arm 2532a of the circumferential locking body 253 is deformed to be restorable, the circumferential locking portion 255 is separated from one circumferential limiting groove 2121 and then slides along the hole wall of the circumferential limiting hole 212, when the circumferential locking portion 255 is snapped into another adjacent circumferential limiting groove 2121 again, the connecting arm 2532a is restored to the original shape, at this time, the axial locking portion 2523 is retained in the axial limiting groove 2323 and abuts against the bottom wall of the axial limiting groove 2323 in the first direction, the locking knob assembly 25 is in the locked state, and the movable housing 23 is fixedly connected to the fixed housing 21.

The unlocking process of the locking knob assembly 25 described above is as follows:

first, the locking knob cover 256 is held, and the locking knob cover 256 is rotated counterclockwise or clockwise by 90 °, and the circumferential locking portion 255 is disengaged from the circumferential retaining groove 2121 and then snapped into another adjacent circumferential retaining groove 2121, at which time the axial locking portion 2523 is disengaged from the axial retaining groove 2323 and aligned with the axial retaining hole 2321. Then, the locking knob assembly 25 is pulled out in the first direction, the axial locking portion 2523 penetrates the axial limiting hole 2321 in the first direction to disengage from the first limiting portion 232, the circumferential locking portion 255 also disengages from the circumferential limiting groove 2121, the locking knob assembly 25 can be completely separated from the fixed housing 21 and the movable housing 23, and at this time, the movable housing 23 is automatically opened under the action of the elastic member 27.

In the vacuum cleaner housing 20 and the vacuum cleaner 100 provided with the same, the locking knob assembly 25 can rotate 90 degrees around the first direction along the counterclockwise direction or the clockwise direction relative to the fixed housing 21 to switch between the unlocked state and the locked state, so that the movable housing 23 can be opened and closed only by arbitrarily rotating the locking knob cover 256. Since the first locking section 2532 can provide a clear tactile sensation and sound feedback to the user when it is engaged in the circumferential retaining groove 2121, it can be known whether the brush assembly 40 has been rotated to the desired position without eye observation, and the movable housing 23 can be opened or closed conveniently and quickly to replace or clean the brush assembly.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
