Description

Technical Field

[0001] The utility model relates to the technical field of floor cleaning equipment, in particular to a floor cleaning tool used for vacuuming a floor to be cleaned and wiping the floor with a replaceable cleaning sheet. Background Art

[0002] Stick vacuum cleaners are known in the art. These vacuum cleaners are typically lighter than traditional upright vacuum cleaners and lack the driven brush roll of traditional vacuum cleaners. The lighter weight and lack of a brush roll make these cleaners easier for users to maneuver. They can also be used on a wider variety of surfaces than traditional upright vacuum cleaners.

[0003] Electric vacuum cleaners, such as stick vacuum cleaners, are widely used in the field of floor cleaning to suck up debris from the floor to be cleaned. The sucked-up debris can be collected in a dust collection chamber. Dust collection chambers are known, either with disposable dust boxes or reusable dust boxes that can be emptied of debris.

[0004] Another way to remove debris from the floor is to use a mop. A mop carries a cleaning sheet on the bottom of the mop head. By moving the mop head, debris from the floor is adhered to the sheet. Common cleaning sheets include those with electrostatic attraction or those soaked in liquid. Replaceable cleaning sheets (also known as "disposable cleaning sheets") are widely used because they can be discarded after use.

[0005] In the prior art, multifunctional floor cleaning tools that combine a push-rod vacuum cleaner and a cleaning mop have also been launched, but there is still room for improvement in terms of improving cleaning efficiency and improving ease of use. Utility Model Content

DETAILED DESCRIPTION

[0025] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0026] See also Figure 1 , which shows a floor cleaning tool 100 according to an embodiment of the present application, which can be attached to the lower part of a handle bar assembly 200 carrying a suction motor (not shown in the figure). When the floor cleaning tool 100 is in operation, it can move on the floor to be cleaned.

[0027] See also Figure 2 and Figure 3 The floor cleaning tool 100 includes a mop head assembly 1, an adapter connector 2, and a dust box assembly 3. The dust collecting component 3 is arranged on the front side of the mop head assembly 1, and the dust box assembly 3 can be in the dust collecting position relative to the mop head assembly 1 (see FIG. Figure 2 ) and non-dust collection locations (see Figure 3 ), when the operator pushes the floor cleaning tool 100 forward, the dust suction component 3 can first suck up the debris on the floor to be cleaned, and then the mop head assembly 1 wipes the vacuumed floor to be cleaned.

[0028] See also Figure 4 The mop head assembly 1 includes a first shell 11 for carrying a replaceable cleaning sheet (not shown in the figure). When the replaceable cleaning sheet is detachably coupled to the first shell 11, the replaceable cleaning sheet can contact the floor to be cleaned. In this example, the top of the first shell 11 is provided with a plurality of rag fixing seats 12 for fixing the corners of the replaceable cleaning sheet, and the plurality of rag fixing seats 12 are specifically located at the four corners of the top. The four corners of the replaceable cleaning sheet can be respectively inserted into the corresponding rag fixing seats 12 to fix the replaceable cleaning sheet to the first shell 11. A pair of bosses 13 opposite to each other are provided on the top of the first shell 11.

[0029] The adaptor connector 2 is attached to the first housing 11. The rotating connector 2 is configured to engage with the lower portion of the handle bar assembly 200. The rotating connector 2 has a pair of upper connecting portions 21 and a pair of lower connecting portions 22.

[0030] Continue as Figure 1As shown, the pair of upper connecting portions 21 are rotatably connected with the lower portion of the handle bar assembly 200 and define a first axis of rotation L1 extending along the front-to-rear direction. The pair of lower connecting portions 22 are rotatably connected with the pair of shoulders 13 of the first housing 31 and define a second axis of rotation L2 extending along the left-to-right direction. The pair of lower connecting portions 22 are located inside the pair of shoulders 13 and engage with the inner side wall surfaces of the pair of shoulders 13.

[0031] Referring to Figure 2 and Figure 3 , the dust box assembly 3 is rotatably connected to the first housing 11 between a dusting position and a non-dusting position. In combination Figure 4 , the dust box assembly 3 includes a second housing 31 having a dusting port 311 at a front portion, a dust box 32 disposed on the second housing 31 and in fluid communication with the dusting port 311, and an air discharge passage 33 disposed on the second housing 31 and in fluid communication with the dust box 32. The air discharge passage 33 is fluidly connectable to a suction end of the suction motor via a flexible duct 300 (see Figure 1 ) passing through the adapter connector 2.

[0032] The second housing 31 includes a pair of rear end portions 312 distributed left and right. The pair of rear end portions 312 are rotatably connected with the pair of shoulders 13, thereby rotatably connecting the second housing 31 with the first housing 11. The pair of rear end portions 312 are located outside the pair of shoulders 13.

[0033] Referring to Figure 4 , the dust box 32 is configured with a dust box cover 321 located at a bottom portion of the second housing 31. The dusting port 311 is arranged front-to-rear adjacent to the dust box cover 321.

[0034] Opening the dust box cover 321, debris in the dust box 32 can be discharged. The second housing 31 is provided with a dust box cover release button 34 for a user to trigger the dust box cover 321 to open the dust box 32.

[0035] A front side end portion 3211 of the dust box cover 321 is hinged to the second housing 31, and a rear side end portion 3212 of the dust box cover 321 is releasably engaged with the second housing 31. The dust box cover release button 34 is drivingly disposed with the rear side end portion 3212 of the dust box cover 321.

[0036] Referring to Figure 5 , when the user operates the dust box cover release button 34, the rear side end portion 3212 of the dust box cover 321 will be triggered to be separated from the second housing 31, and the dust box cover 321 is rotated downward, thereby opening the dust box 32. Debris in the dust box 32 can also be discharged thereby.

[0037] The dust box assembly 3 further includes a filter 35 disposed in the air discharge passage 33. Air entering the air discharge passage 33 will be filtered by the filter 35.

[0038] The second housing 31 further comprises an openable top cover 310. The filter 35 is located on the inner side of the top cover 310. When the top cover 310 is opened, the filter 35 can also be taken out.

[0039] In order to facilitate the dust box assembly 3 to be maintained in the dust collection position and the non-dust collection position, in some embodiments, a limiting mechanism for locking the dust box assembly 3 in one of the dust collection position and the non-dust collection position may be provided between the second housing 31 and the first housing 11. The locking mechanism may be specifically arranged at the junction of at least one rear end portion 312 and the corresponding boss 13.

[0040] like Figure 6 As shown, when the floor cleaning tool 100 is in operation, debris and air are sucked into the dust box 32 from the suction port 311. The air passes through the filter 35 and flows backward from the air discharge channel 33, and the debris is trapped in the dust box 32. When the debris in the dust box 32 needs to be cleaned, the dust box cover release button 34 is opened to open the dust box cover 321, and the debris falls out.

[0041] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
