[0025] In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the present application. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the concept of the present application, the specific shapes, structures and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment.

[0026] Refer to Figure 1 , which shows a floor cleaning head 100 designed according to the technical solution of the present application. The floor cleaning head 100 can be attached to the lower part of a handle rod assembly carrying a vacuum suction component. The vacuum suction component may include a dust box, a vacuum motor fluidly connected to the dust box, and a battery for powering the vacuum motor; in an alternative battery power supply scheme, the vacuum suction component may further include a power cord that can be connected to a household electrical outlet, etc. In some solutions, the handle rod assembly may also carry a liquid supply container filled with a cleaning liquid; the liquid supply container can supply the cleaning liquid to the floor or the floor cleaning head.

[0027] The floor cleaning head 100 includes a square base body 1 and a suction nozzle assembly 3 mounted on the base body 1. The base body 1 is constructed to be able to install the cleaning cloth 200 shown in the figure. The cleaning cloth 200 can be either a disposable cleaning cloth or a reusable cleaning cloth; the cleaning cloth can be a dry cleaning cloth or a cleaning cloth pre-soaked with a cleaning liquid. The cleaning cloth 200 shown in this example has a square body 201 adapted to the length and width of the base body 1, and the front and rear sides of the body 201 form a front wing 202 and a rear wing 203. When the cleaning cloth 200 is installed on the base body 1, the body 201 is located at the bottom lower side of the base body 1, and the front wing 202 and the rear wing 203 are locked at the top of the base body 1.

[0028] See also Figure 2 The seat body 1 can be assembled from one or more parts. In this example, the seat body 1 includes an upper shell 11, a lower shell 12 and a support plate 13. The support plate 13 is located between the upper shell 11 and the lower shell 12. The upper shell 11 defines the top of the seat body 1, and a pair of bosses 14 distributed left and right are provided in the middle of the upper shell 11; except for the pair of bosses 14, the rest of the upper shell 11 is generally flat.

[0029] The support plate 13 will play a role in supporting the lower housing 12 and other parts. More parts on the seat body 1 are all mounted on the support plate 13. The support plate 13 is a plastic component with reliable strength.

[0030] See also Figure 3 The lower shell 12 has a bottom surface 121, and the bottom surface 121 is provided with concave-convex patterns 122. The bottom surface 121 of the lower shell 12 defines a substantially flat bottom of the seat body by being made of a flexible material. The lower shell 12 is usually made of a flexible material, such as sponge, foam, etc., which can facilitate the cleaning cloth 200 to better contact the floor to be cleaned. The middle part of the lower shell 12 has a through opening 123.

[0031] Continue to see Figure 1, a rotating connector 15 is also connected to the upper housing 11. In this example, the rotating connector 15 is a connector providing two degrees of rotational freedom, including a lower part 151 and an upper part 152. Among them, the lower part 151 can be rotatably connected to a pair of shoulders 14 around a transverse axis X1 extending in the left-right direction, and the lower part 151 is entirely located inside the pair of shoulders 14. The upper part 152 can be rotatably connected to the upper part 151 around a longitudinal axis Y1 extending in the front-back direction. The lower part of the handle rod assembly mentioned above can be connected to the upper part 152.

The upper part of the upper part 152 is tubular, and after it is connected to the lower part of the handle rod assembly, the two will be able to form fluid communication.

[0032] The suction nozzle assembly 3 includes a suction nozzle housing 31 and a flexible pipe 32. A suction port 311 is provided below the front of the suction nozzle housing 31. A suction channel (not shown in the figure) extending backward from the suction port 311 is provided inside the suction nozzle housing 31, and the suction pipe 32 will be connected to the flexible pipe 32. The rear part of the suction nozzle housing 31 has a pair of swing arms 312. The pair of swing arms 312 can be rotatably connected to a pair of shoulders 14 around a transverse axis X1 extending in the left-right direction. The suction nozzle housing 31 can rotate between a dust suction position and a non-dust suction position.

[0033] As Figure 4 shown, when the suction nozzle housing 31 is in the dust suction position, the suction port 311 is located at the front of the base body 1 and faces the floor to be cleaned; when in the non-dust suction position, the suction port 311 is flipped to directly above the base body 1.

[0034] As Figure 5 shown, when the suction nozzle housing 31 is in the non-dust suction position, the user is allowed to install the front side wings 202 of the cleaning cloth 200 at the upper housing 11.

[0035] Combined Figure 2 shown, a pair of suction nozzle limit members 16 with convex portions 161 are also arranged on the upper housing 11 at positions close to the pair of shoulders 14.

[0036] Continue to refer to Figure 4 and Figure 5 , each swing arm 313 has an outer peripheral surface 3121, and a first notch 3122 and a second notch 3123 are respectively provided on the outer peripheral surface 3121 along the circumferential direction. As Figure 4 shown, when the convex portion 161 of the suction nozzle limit member 16 is inserted into the first notch 3122, the suction nozzle housing 31 will be held in the dust suction position. As Figure 5As shown, when the convex portion 161 of the nozzle stopper 16 is inserted into the second notch 3123, the nozzle housing 31 will be held in the non-vacuuming position. When the user applies a rotational force to the nozzle housing 31, the convex portion 161 of the nozzle stopper 16 will be able to separate from the first notch 3122 or the second notch 3123.

[0037] Continue to refer to Figure 2 , a cloth clamping assembly 4 and a cloth unloading assembly 5 are also installed on the base body 1. The cloth clamping assembly 4 is used to lock the cleaning cloth 200 on the base body 1. The cloth unloading assembly 5 is used to assist in unloading the cleaning cloth 200 from the base body 1.

[0038] The cloth clamping assembly 4 includes a pair of clamping plates 41. The pair of clamping plates 41 are distributed left and right. Each clamping plate 41 has a connecting end 411. In this example, the connecting end 411 of each clamping plate 41 passes through the upper housing 11 and is rotatably connected to the support plate 13 about a longitudinal axis Y2 extending in the front-rear direction. A torsion spring 42 is provided between each clamping plate 41 and the support plate 13. The pair of clamping plates 41 can rotate between a closed position and an open position about the longitudinal axis Y2.

[0039] Refer to Figure 6 , when the pair of clamping plates 41 are in the closed position, the pair of clamping plates 41 are in contact with the upper housing 11, and the torsion spring 42 is in an elastically deformed state; at this time, the front side wing 201 and the rear side wing 202 of the cleaning cloth 200 will be able to be locked at the upper housing 11.

[0040] Refer to Figure 7 , when the pair of clamping plates 41 are in the open position, the pair of clamping plates 41 are away from the upper housing 11; at this time, the front side wing 201 and the rear side wing 202 of the cleaning cloth 200 can be placed at the upper housing 11 or removed from the upper housing 11.

[0041] Continue to refer to Figure 6 and Figure 7 , the clamping plate 41 is in a T shape, a pair of clamping areas P are defined on the upper housing 11, and a pair of recesses 111 matching the shape of the pair of clamping plates 41 are provided at each clamping area P; when the pair of clamping plates 41 are in the closed position, each clamping plate 41 is located within the corresponding recess 111. In addition, in order to better lock the front side wing and the rear side wing of the cleaning cloth, friction bumps 112 are provided in each recess 111. In other embodiments, friction bumps can also be provided on the clamping plate 41.

[0042] Such as Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, a latch member 7 is provided on the support plate 13. The latch member 7 is movably provided on the support plate 13 in the front - rear direction. The latch member 7 is configured to releasably hold a pair of clamping plates 41 in a closed position. The latch member 7 includes a pair of locking blocks 71 distributed left - and - right. Each clamping plate 41 is provided with a locking groove 412. The locking groove 412 is opposite to the locking block 71 in the front - rear direction. When the latch member 7 is in the locked position, the locking block 71 is inserted into the locking groove 412, and the clamping plate 41 is prevented from rotating about the longitudinal axis Y2; when the latch member 7 is in the released position, the locking block 71 leaves the locking groove 412, and each clamping plate 41 will be able to rotate about the longitudinal axis Y2 to the open position under the restoring force of the corresponding torsion spring 42.

[0043] Combined with Figure 2 , a spring 8 is provided between the latch member 7 and the support plate 13. The spring 8 can bias the latch member 7 to hold the latch member 7 in the locked position when the acting force on the latch member 7 is completely withdrawn.

[0044] Referring to Figure 10 , the lower part of each clamping plate 41 is also provided with an inclined surface 413; the upper part of the locking block 71 has an inclined surface 711; when each clamping plate 41 rotates from the open position to the closed position, the inclined surface 413 cooperates with the inclined surface 711 and can push the lower - located locking block 71 to move in a direction away from the clamping plate 41, that is, push the latch member 7 towards the released position; and when the inclined surface 413 is separated from the locking block 71, the locking block 71 will move into the locking groove 412 under the action of the spring 8 and be held.

[0045] A pair of push - buttons 9 are also provided on the seat body 1. The lower parts of the pair of push - buttons 9 are slidably mounted on the support plate 13 of the seat body 1 in the left - right direction between a first position and a second position. The upper parts of the pair of push - buttons 9 protrude from the upper housing 11 and are located outside a pair of shoulders 14. The lower part of each push - button 9 is provided with an inclined surface 91. The latch member 7 is provided with a pair of inclined surfaces 72 adapted to the pair of inclined surfaces 91. The latch member 7 is constructed to be actuated by the pair of push - buttons 9 to move forward from the rear. When the push - button 9 is operated by the user to slide from the first position to the second position, the inclined surface 91 will abut against the inclined surface 72 and push the inclined surface 72 to move, and the latch member 7 is moved from the locked position to the released position, thereby realizing the release of the corresponding clamping plate 41.

[0046] A spring 92 is also provided between the lower part of each push - button 9 and the shoulder 14. After the acting force of the user on the push - button 9 is withdrawn, the spring 92 will drive the push - button 9 back to the first position, and the latch member 7 can also be reset to the locked position under the action of the spring 8.

[0047] Continuing to refer to Figure 2, the cloth unloading assembly 5 includes a pair of cloth unloading plates 51. Each cloth unloading plate 51 is hinged to the support plate 13 and is located at the through opening 123 of the lower housing 12. The pair of cloth unloading plates 51 can rotate relative to the support plate 13 between an extended position and a retracted position.

[0048] See Figure 16 and Figure 17 , when the pair of cloth unloading plates 51 are in the extended position, at least part of each cloth unloading plate 51 extends from the through opening 123 of the lower housing 12 and protrudes downward relative to the bottom surface 121 of the lower housing 12.

[0049] See Figure 14 , when the pair of cloth unloading plates 51 are in the retracted position, each cloth unloading plate 51 is substantially flush with the bottom surface 121 of the lower housing 12.

[0050] See Figure 12 , the cloth unloading plate 51 is L-shaped. The cloth unloading plate 51 has a first end 511, a second end 512 and a hinge portion 515 that are away from each other. The hinge portion 515 is close to the second end 512. A spring support seat 513 is further provided on the second end 512 of each cloth unloading plate 51. A protrusion 514 is also provided on the cloth unloading plate 51, and the protrusion 514 is located on the side opposite to the hinge portion 515 with respect to the second end 512.

[0051] Continue as Figure 2 shown, the second ends 512 of the pair of cloth unloading plates 51 are arranged side by side in the front-rear direction, and the pair of cloth unloading plates 51 are hinged to the support plate 13 by the same rotating shaft 52. The rotating shaft 52 defines a longitudinal axis Y3 extending in the front-rear direction.

[0052] As Figure 8 shown, a pair of hollow portions 73 are provided at corresponding positions of the latch member 7, and the spring support seats 513 are located below the pair of hollow portions 73. A spring 53 is supported on each spring support seat 513, and each spring 53 passes through the corresponding hollow portion 73 and abuts against the upper housing 11, that is, the spring 53 is supported between the spring mounting seat 513 and the upper housing 11.

[0053] As Figure 13 , Figure 14 and Figure 15 shown, when the pair of cloth unloading plates 51 are in the retracted position, the protrusion 514 of each cloth unloading plate 51 contacts the wedge portion 74 of the latch member 7. The spring 53 is located between the cloth unloading plate 51 and the upper housing 11.

[0054] At this time, when the user presses a pair of push buttons 9 inward, the pair of push buttons 9 will directly trigger the latch member 7 to move forward, and a pair of locking blocks 71 on the latch member 7 will slide out of the locking grooves 412 of the respective clamping plates 41. The pair of clamping plates 41 will rotate from the closed position to the open position under the action of the corresponding torsion springs 42; at the same time, the forward movement of the latch member 7 will cause a pair of wedge portions 74 to push a pair of protrusions 514 downward, and a pair of cloth unloading plates 51 will flip downward from the retracted position to the extended position; as Figure 16 and Figure 17 the respective component states shown.

[0055] Therefore, in this application, operating the pair of push buttons 9 to slide to the second position will be able to release the pair of clamping plates 41 of the cloth clamping assembly 4, causing them to rotate to the open position under the action of the torsion springs 42, and at the same time triggering the pair of cloth unloading plates 51 of the cloth unloading assembly 5 to rotate from the retracted position to the extended position around the rotation shaft 52; as Figure 16 and Figure 17 the respective component positions.

[0056] When the user releases the pair of push buttons 9, the pair of push buttons 9 will return to the first position under the action of the spring 92, and the pair of cloth unloading plates 51 will be able to return to the retracted position under the action of a pair of springs 53; at this time, the pair of clamping plates 41 will not return to the closed position. At this time, the user needs to apply a downward force to the pair of clamping plates 41, and with the help of the inclined surfaces 413 provided at the lower parts of the respective clamping plates 41 acting on the inclined surfaces 711 of the locking blocks 71, the locking blocks 71 can slide into the locking grooves 412 of the clamping plates 41 again, so as to keep the pair of clamping plates 41 in the closed position.

[0057] When the user needs to load the cleaning cloth 200 on the floor cleaning head 100, when the suction nozzle housing 21 of the suction nozzle assembly 2 is flipped to the non-vacuuming position and the pair of push buttons 9 are moved inward from the first position to the second position, during this process, the pair of push buttons 9 will trigger the pair of clamping plates 41 to switch to the open position; then the front wings and rear wings of the cleaning cloth 200 are respectively placed at the front and rear parts of the upper housing 11, and then the pair of clamping plates 41 are pressed down forcefully and switched to the closed position. The respective clamping plates 41 will move into the corresponding recesses 111 of the upper housing 11, and the front wings 202 and rear wings 203 of the cleaning cloth 200 will be locked at the front and rear positions of the upper housing 11.

[0058] When the user needs to remove the cleaning cloth from the upper housing 11, the user moves a pair of push buttons 9 inward here to move them from the first position to the second position. The pair of push buttons 9 will trigger a pair of clamping plates 41 to switch from the closed position to the open position and at the same time cause a pair of cloth discharging plates 51 to rotate from the retracted position to the extended position. At this time, the part of the cleaning cloth locked on the upper housing 11 has been released by the pair of clamping plates 41. With the action of the pair of cloth discharging plates 51, the main body part 201 of the cleaning cloth 200 will be pushed downward, thereby further pushing the cleaning cloth 200 to be removed from the upper housing 11 and the lower housing 12.
