Description

Technical Field

[0001] The present invention relates to the technical field of floor scrubbers, and in particular to a locking mechanism and floor scrubber equipment. Background Art

[0002] The fully automatic floor scrubber mainly includes a floor brush, a sewage tank, a clean water tank, a main unit, a handle, and a base station. The working principle is that the water pump pumps the water in the clean water tank to spray it onto the roller brush to wet the roller brush, and the roller brush rotates to achieve a cleaning effect. The vacuum motor in the main unit generates suction, and the sewage is sucked into the pipe through the suction port on the floor brush and sent to the sewage tank. The handle assembly plays a role in control and human-computer interaction. After use, the floor scrubber is returned to the base station to achieve fully automatic sewage discharge, cleaning, and charging.

[0003] After the floor scrubber is used, it is returned to the base station for charging and sewage discharge. During the sewage discharge process, if the floor scrubber moves, for example, if the floor scrubber is accidentally lifted, the sewage in the sewage tank may easily leak out of the base station. It is necessary to clean the sewage outside the base station separately, which is troublesome.

[0004] During the sewage discharge process, the floor scrubber moves mainly because after the floor scrubber is placed in the base station, the base station does not have a related structure to jam the floor scrubber body, making it unable to move. When the floor scrubber body is accidentally touched, it may cause sewage to flow out of the base station. Summary of the invention

[0005] The main purpose of the present invention is to provide a locking mechanism and a floor scrubber device to achieve locking of a floor scrubber body and a base station.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a locking mechanism is provided, which includes: a slot, which is arranged on a first matching piece; an insert piece, which is arranged on a second matching piece, and the insert piece is movably arranged along a preset direction so that at least part of the insert piece extends out or retracts into the second matching piece, thereby making the insert piece have an original retracted state and an extended state; one of the floor scrubber body and the base station is the first matching piece, and the other is the second matching piece; wherein, when the floor scrubber body enters the base station, the insert piece is in the original retracted state; when the floor scrubber body is placed in the base station, at least part of the insert piece extends out from the second matching piece, so that the insert piece is switched to the extended state, and the part of the insert piece located outside the second matching piece is inserted into the slot on the first matching piece, thereby locking the floor scrubber body and the base station; when the floor scrubber body leaves the base station, the part of the insert piece extending from the second matching piece to the outside of the second matching piece is retracted into the second matching piece again to avoid the floor scrubber body, and the insert piece is switched to the original retracted state.

[0007] Furthermore, the locking mechanism also includes a gear and a rack that mesh with each other, the rack is fixedly arranged on the plug-in component; the gear is rotatably arranged on the second matching component around its central axis, and the axial direction of the gear is perpendicular to the preset direction, so that the gear drives the plug-in component to move along the preset direction.

[0008] Furthermore, the locking mechanism also includes a driving member, the main body of which is fixedly arranged on the housing of the second matching member; and the output portion of the driving member is connected to the gear to drive the gear to rotate.

[0009] Furthermore, a first slide groove is provided on one of the housing and the plug-in component of the second mating component, and a sliding portion is provided on the other; the first slide groove is extended along a preset direction, and the sliding portion is slidably provided in the first slide groove, so that when the plug-in component moves along the preset direction, the sliding portion slides along the first slide groove to guide the movement of the plug-in component.

[0010] Furthermore, a protrusion is provided on one of the slot wall and the plug-in piece of the slot, and a second slide groove is provided on the other; the second slide groove is extended along a preset direction so that when the part of the plug-in piece located outside the second matching piece is inserted into the slot or removed from the slot, the protrusion is located in the second slide groove and slides along the second slide groove.

[0011] Furthermore, the protrusion is arranged on the plug-in component; a supporting portion is arranged on the housing of the second matching component, and the supporting portion contacts the protrusion to support the plug-in component; wherein, when the plug-in component moves along a preset direction, the protrusion moves relative to the supporting portion.

[0012] Furthermore, the second mating piece has an installation cavity and a preset opening connected to the installation cavity, and at least part of the plug-in piece extends out of or retracts into the installation cavity through the preset opening to achieve at least part of the plug-in piece extending out of or retracting into the second mating piece.

[0013] Further, the slot or the insert is arranged at the sewage discharge part of the floor scrubber body, and the insert or the slot is arranged at the sewage suction part of the base station.

[0014] Furthermore, the plug-in component is used to communicate with the control module of the second matching component, so that the control module controls the plug-in component to switch between an original retracted state and an extended state.

[0015] According to another aspect of the present invention, a floor scrubber device is provided, which includes a floor scrubber body, a base station and the above-mentioned locking mechanism.

One of the floor scrubber body and the base station is the first matching piece, and the other is the second matching piece.

[0017] When the floor scrubber body is about to enter the base station, the insert is in the original retracted state, or switched from the extended state to the original retracted state, so that the insert avoids the floor scrubber body to prevent the insert from interfering with the entry action of the floor scrubber body.

[0018] When the main body of the floor scrubber enters or is placed in the base station, the plug-in moves in a preset direction so that at least part of the plug-in extends from the second fitting, so that the plug-in switches from the original retracted state to the extended state, and the part of the plug-in outside the second fitting is inserted into the slot on the first fitting, thereby locking the main body of the floor scrubber and the base station. In this way, when the main body of the floor scrubber performs self-cleaning and sewage discharge at the base station, that is, during the sewage discharge process of the floor scrubber, the main body of the floor scrubber can be locked with the base station to maintain relative stillness, thereby avoiding accidental collision that causes the main body of the floor scrubber to move, and further avoiding the phenomenon of sewage leakage during the sewage discharge process, so that the sewage discharge process is not affected and the sewage discharge process is ensured to be completed normally.

[0019] When the main body of the floor scrubber is about to leave the base station, the plug-in component moves in a preset direction so that the portion of the plug-in component that extends from the second fitting component to the outside of the second fitting component is retracted into the second fitting component to avoid the main body of the floor scrubber, that is, the plug-in component switches from an extended state to an original retracted state to avoid interference with the leaving action of the main body of the floor scrubber.

[0042] Please refer to Figures 1 to 12 The locking mechanism includes a slot 30 and an insert 40, the slot 30 is arranged on the first mating piece, and the insert 40 is arranged on the second mating piece; the insert 40 is movably arranged along a preset direction so that at least part of the insert 40 can be extended or retracted into the second mating piece, thereby making the insert 40 have an original retracted state and an extended state.

[0043] When the floor scrubber body 10 is about to enter the base station 20 , the insert 40 is in the original retracted state, or switched from the extended state to the original retracted state, so that the insert 40 avoids the floor scrubber body 10 to prevent the insert 40 from interfering with the entry action of the floor scrubber body 10 .

[0044] When the floor scrubber body 10 enters or is placed in the base station 20, the plug-in part 40 is moved in a preset direction so that at least part of the plug-in part 40 extends from the second fitting part, so that the plug-in part 40 is switched from the original retracted state to the extended state, and the part of the plug-in part 40 outside the second fitting part is inserted into the slot 30 on the first fitting part, thereby locking the floor scrubber body 10 and the base station 20. In this way, when the floor scrubber body 10 performs self-cleaning and sewage discharge at the base station 20, that is, during the sewage discharge process of the floor scrubber, the floor scrubber body 10 can be locked with the base station 20 to maintain relative stillness, thereby avoiding accidental collision and causing the floor scrubber body 10 to move, thereby avoiding the phenomenon of sewage leakage during the sewage discharge process, so that the sewage discharge process is not affected and the sewage discharge process is ensured to be completed normally.

At this time, the first body section can avoid the floor scrubber body 10, so that the floor scrubber body 10 enters or leaves the base station 20. The insert 40 is movably arranged along a preset direction so that at least part of the second body section extends or retracts the second matching piece, thereby switching the insert 40 between the original retracted state and the extended state.

[0066] Optionally, when the protrusion 46 is disposed on the insert 40 , at least a portion of the protrusion 46 is disposed on the first body segment.

[0071] Optionally, when the insert 40 is in the original retracted state, the first body section is located outside the mounting cavity 48, and the second body section is located inside the mounting cavity 48. The insert 40 is movably arranged along a preset direction so that at least part of the second body section extends out of or retracts into the mounting cavity 48 through the preset opening 481.

[0072] In the present application, the floor scrubber body 10 includes a sewage discharge part, and the sewage discharge part of the floor scrubber body 10 is provided with a sewage discharge port 11; the base station 20 includes a sewage suction part, and the sewage suction part of the base station 20 is provided with a sewage suction port 21; when the floor scrubber body 10 is placed in the base station 20, the sewage discharge part of the floor scrubber body 10 contacts the sewage suction part of the base station 20, so that the sewage discharge port 11 of the floor scrubber body 10 is connected with the sewage suction port 21 of the base station 20, so that the sewage in the floor scrubber body 10 is discharged through the sewage discharge port 11 and enters the sewage tank of the base station 20 through the sewage suction port 21 of the base station 20.

[0073] Specifically, the slot 30 or the insert 40 is arranged at the sewage discharge part of the floor scrubber body 10, and the insert 40 or the slot 30 is arranged at the sewage suction part of the base station 20; when the floor scrubber body 10 is placed in the base station 20, the sewage discharge part of the floor scrubber body 10 and the sewage suction part of the base station 20 are locked by the locking mechanism.

[0074] The present invention also provides a floor scrubber device, such as Figures 1 to 12 As shown, it includes a floor scrubber body 10, a base station 20 and the above-mentioned locking mechanism.

[0075] In the present application, the plug-in component 40 is used to communicate with the control module of the second matching component, so that the control module of the second matching component controls the plug-in component 40 to switch between the original retracted state and the extended state.

[0076] Specifically, the driving member 43 is used to communicate with the control module of the second matching member, so that the control module of the second matching member controls the driving member 43, and further controls the insertion member 40 to switch between the original retracted state and the extended state.

[0077] Specifically, when the control module of the second matching component determines that the floor scrubber body 10 is placed in the base station 20, the driving component 43 is controlled to move (rotate) so that the driving component 43 drives the plug-in component 40 to move in a preset direction, thereby switching the plug-in component 40 from the original retracted state to the extended state; when the plug-in component 40 is switched to the extended state, the control module of the second matching component controls the driving component 43 to stop moving (rotate) so that the plug-in component 40 remains in the extended state, so that the floor scrubber body 10 and the base station 20 remain in the locked state, and prevent the floor scrubber body 10 from moving. When the control module of the second matching component determines that the floor scrubber body 10 is about to leave the base station 20, the driving component 43 is controlled to move (rotate) so that the driving component 43 drives the plug-in component 40 to move in a preset direction, thereby switching the plug-in component 40 from the extended state to the original retracted state.

[0078] When the second matching component is the base station 20, when the base station 20 senses that the floor scrubber body 10 is placed in the base station, the control module of the base station 20 controls the driving component 43 to move (rotate) so that the driving component 43 drives the plug-in component 40 to move in a preset direction, thereby switching the plug-in component 40 from an original retracted state to an extended state.

[0079] Optionally, after the sewage discharge step is completed, the floor scrubber body 10 is moved away from the base station 20 .

[0080] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0081] In the locking mechanism used in the floor scrubber provided by the present invention, the locking mechanism includes a slot 30 and an insert 40, wherein the slot 30 is arranged on the first mating piece, and the insert 40 is arranged on the second mating piece; the insert 40 is movably arranged along a preset direction, so that at least part of the insert 40 extends or retracts into the second mating piece, thereby making the insert 40 have an original retracted state and an extended state. One of the floor scrubber body 10 and the base station 20 is the first mating piece, and the other is the second mating piece.

[0082] When the floor scrubber body 10 is about to enter the base station 20 , the insert 40 is in the original retracted state, or switched from the extended state to the original retracted state, so that the insert 40 avoids the floor scrubber body 10 to prevent the insert 40 from interfering with the entry action of the floor scrubber body 10 .

[0083] When the floor scrubber body 10 enters or is placed in the base station 20, the plug-in part 40 is moved in a preset direction so that at least part of the plug-in part 40 extends from the second fitting part, so that the plug-in part 40 is switched from the original retracted state to the extended state, and the part of the plug-in part 40 outside the second fitting part is inserted into the slot 30 on the first fitting part, thereby locking the floor scrubber body 10 and the base station 20. In this way, when the floor scrubber body 10 performs self-cleaning and sewage discharge at the base station 20, that is, during the sewage discharge process of the floor scrubber, the floor scrubber body 10 can be locked with the base station 20 to maintain relative stillness, thereby avoiding accidental collision and causing the floor scrubber body 10 to move, thereby avoiding the phenomenon of sewage leakage during the sewage discharge process, so that the sewage discharge process is not affected and the sewage discharge process is ensured to be completed normally.

[0084] When the floor scrubber body 10 is about to leave the base station 20, the plug-in component 40 is moved in a preset direction so that the portion of the plug-in component 40 extending from the second fitting component to the outside of the second fitting component is retracted into the second fitting component to avoid the floor scrubber body 10, that is, the plug-in component 40 is switched from the extended state to the original retracted state to avoid the plug-in component 40 interfering with the leaving action of the floor scrubber body 10.
