[0025] Reference is now made to the accompanying drawings, which are shown for the sole purpose of illustrating the preferred embodiments of the application and are not to be construed as limiting thereof.

[0026] Figure 1 There is shown a floor cleaning device 100 adapted to clean hard floors such as floor tiles. The floor cleaning device 100 combines the functions of mopping and vacuuming, and after use, allows the user to discard or replace the dust box and cleaning sheets.

[0027] The cleaning device 100 includes a cleaning base 1 for moving on the floor to be cleaned and an elongated handle body part 2, the lower part of which is rotatably connected to the cleaning base 1. During the cleaning operation, the handle body part 2 can tilt backward relative to the cleaning base 1, or swing left or right, so as to lead the cleaning base 1 to move as required on the floor to be cleaned under the manipulation of the handle body part 2.

[0028] The handle body part 2 includes a housing 21, a vacuum source unit 22 arranged at the housing 21, and a handle rod assembly 23 mounted on the upper part of the housing 21. The handle rod assembly 23 includes a rod 231, a handle 232, and a plurality of control buttons 233. The vacuum source unit 22 at least includes a vacuum motor and a power supply module for supplying electrical energy to the vacuum motor, and the vacuum motor can generate a vacuum when started, thereby driving the outside air to flow towards it.

[0029] As Figures 2 - 4 The cleaning base 1 shown, includes a base 11, a detachable module 10 detachable from the base 11, and a rotary joint 14 mounted at the rear of the base 11. The detachable module 10 is composed of a replaceable dust box 12 and an upper cover 13.

[0030] The base 11 is configured to removably support a replaceable cleaning cloth, which can be a disposable cleaning sheet that can be discarded, etc. The bottom of the base 11 has a bottom surface 111 and a pair of clamping portions 112 on both sides of the bottom surface 111. The front of the base 11 is provided with a dust suction port 113 facing the ground to be cleaned, and the dust suction port 113 is located on the front side of the bottom surface 111. When the replaceable cleaning cloth is supported on the base 11, the replaceable cleaning cloth covers below the bottom surface 111, and a pair of side portions of the replaceable cleaning cloth are clamped by the pair of clamping portions 112, so that the replaceable cleaning cloth is held at the bottom surface 111, and the dust suction port 113 is located on the front side of the replaceable cleaning cloth.

[0031] As Figures 4 - 5 shown, the upper part of the base 11 has an open installation chamber 114, and the separable module 10 can be releasably held in the installation chamber 114. A first pair of interfaces 115 communicating with the dust suction port 113 are provided on the front wall surface of the installation chamber 114, and a second pair of interfaces 116 fluidly communicating with the vacuum source unit 22 are provided on the rear wall surface of the installation chamber 114. A pair of left and right distributed protrusions 117 are provided on the inner bottom wall of the installation chamber 114. A pair of front and rear distributed locking blocks 118 are respectively provided on the left side and the right side of the installation chamber 114. As Figures 6 - 7 shown, after the detachable module 10 is separated from the base 11, the replaceable dust box 12 can be separated from the upper cover 13. The replaceable dust box 12 is an integral member and can be made of materials such as polystyrene, polypropylene, and pulp when used as a disposable component that can be discarded.

[0032] The replaceable dust box 12 has a closed bottom wall 121, side walls 122 extending upward from the bottom wall 121, and an open top. The bottom surface of the bottom wall 121 has a pair of inwardly recessed portions 123. The upper part of the side wall 122 has an annular frame 125 extending around the entire circumference of the side wall 122, and the annular frame 125 has an upper surface 126. In this example, the annular frame 125 defines the opening of the open top. The front of the side wall 122 has an opening 124.

[0033] The upper cover 13 can be detachably engaged with the base 11 and cover the open top of the replaceable dust box 12. The upper cover 13 is a plastic member and has a first side portion 131 and a second side portion 132 opposite to each other on the left and right. A pair of front and rear distributed engaging portions 133 are provided at the lower parts of the first side portion 131 and the second side portion 132 of the upper cover 13, and an outwardly facing bayonet 134 is provided on each engaging portion 133. The upper cover 13 is also provided with a gripping portion 135 for the user to grasp the upper cover 13 and a transparent observation window 136. A release button 137 is also provided on the first side portion 131 and the second side portion 132 of the upper cover 13 respectively. The rear of the upper cover 13 has an opening 1311.

[0034] In other embodiments, the detachable engagement between the upper cover and the base can also be achieved by magnetic attraction. For example, a magnet or a ferromagnetic component is provided on one of the upper cover and the base, and a magnet or a ferromagnetic component is provided on the other component.

[0035] As Figures 8 - 9 As shown, a lock 138 is further installed on each of the first side portion 131 and the second side portion 132 of the upper cover 13. The pair of locks 138 are configured to be able to engage with the replaceable dust box 12 to releasably hold the replaceable dust box 12 on the upper cover 13. In this example, the lock 138 is a spring-biased lock and includes a hook portion 1381 at the lower part. The lock 138 is supported on the upper cover 13 by a spring 139. And in this example, the lock 138 and the corresponding release button 137 are an integral component. A circumferentially extending rib 1310 is further provided at the lower part of the upper cover 13. The material of the rib 1310 is preferably an elastic material. In other embodiments, the rib can be defined, for example, by an elastic sealing ring fitted on the lower surface of the upper cover.

[0036] When the upper cover 13 is engaged with the replaceable dust box 12, the upper cover 13 covers the open top. The rib 1310 contacts the upper surface 126 from above on the upper surface 126 of the annular frame 125 to make a sealing contact with the upper surface 126. Thus, the upper cover 13 and the replaceable dust box 12 define a storage chamber 15. The hook portions 1381 of the respective locks 138 hook the annular frame 125 from the lower side of the annular frame 125, thereby realizing releasably holding the replaceable dust box 12 on the upper cover 13. When the user presses the pair of release buttons 137, the corresponding hook portions 1381 of the pair of locks 138 will leave the annular frame 125 of the replaceable dust box 12, and the replaceable dust box 12 is allowed to disengage from the upper cover 13. At this time, once the hook portions 1381 leave the annular frame 125, the replaceable dust box 12 will naturally fall under the action of gravity, thereby realizing the separation of the replaceable dust box 12 from the upper cover 13.

[0037] When the separable module 10 composed of the upper cover 13 and the replaceable dust box 12 is installed in the installation chamber 114 of the base 11, a pair of protrusions 117 on the installation chamber 114 will engage in a pair of recesses 123 on the bottom wall 121 of the replaceable dust box 12, so as to form positioning in the left-right and front-back directions between the separable module 10 and the base 11.

[0038] As Figure 10As shown, when the separable module 10 formed by the upper cover 13 and the replaceable dust box 12 is installed in the installation chamber 114 of the base 11, each engaging portion 133 on the upper cover 13 will undergo elastic deformation, causing the latch 118 on the base 11 to engage with the bayonet 134 thereon. Combining with the positioning effect of a pair of concave portions 123 and a pair of convex portions 117, the upper cover 13 is thus fixed and held on the base 11. When the user applies a force to the upper cover 13, causing the engaging portion 133 to undergo elastic deformation and disengage from the latch 118, the user can remove the separable module 10 from the base 11. When the user separates the separable module 10 from the base 11 and then applies an inward force to a pair of release buttons 137, the replaceable dust box 12 can be detached.

[0039] As Figure 11 shown, when the separable module 10 is installed in the installation chamber 114 of the base 11, the first interface 115 is fluidly connected to the opening 124 on the replaceable dust box 12 in a fluidly connected manner, and the second interface 116 is fluidly connected to the opening 1311 on the upper cover 113 in a fluidly connected manner. Thus, an air flow suction path is realized from the suction port 113, sequentially passing through the first interface 115, the opening 124, the storage chamber 15, the opening 1311, and the second interface 116. When the vacuum source unit 22 is activated, the dust on the ground can be sucked into the air flow suction path along with the air.

[0040] The floor cleaning device of the present application is such that the separable module 10 can be carried away from the base 11 with one hand, and when the separable module 10 is brought above the trash can and then the release button 137 is pressed with the other hand, the replaceable dust box 12 can be separated from the upper cover 13. The separated replaceable dust box 12 together with the internal garbage can fall into the trash can; during the process of detaching the replaceable dust box 12, the user does not need to touch the replaceable dust box 12 with their hands.

[0041] The above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable those familiar with this technology to understand the content of the present application and implement it accordingly, and it cannot be used to limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.
