Description

Technical Field

[0001] This invention relates to the field of cleaning equipment, and in particular to a cleaning mop. Background Technology

[0002] A cleaning mop is currently available, comprising a cleaning head with at least one cleaning attachment and a handle body rotatably connected to the cleaning head. The handle body has a use position tilted towards the cleaning head for the user to push the mop, and a stop position upright for the user to store the mop. However, when the handle body is in the stop position, the mop is only supported on the ground by the cleaning components, resulting in low stability and a tendency to tip over. Therefore, existing cleaning mops often require a separate support base to maintain a stable upright stop position, which is inconvenient to use. Summary of the Invention

[0003] In view of the aforementioned technical problem that the cleaning mop has low stability when the handle body is in the stopped position, the object of the present invention is to provide a cleaning mop with a rear support component.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cleaning mop, comprising a cleaning head and a handle body located on the upper side of the cleaning head, the lower part of the handle body being rotatably connected to the cleaning head about a first transverse axis, the handle body having an inclined use position and an upright stop position; the cleaning head comprising a housing and at least one cleaning attachment located at the bottom of the housing, the cleaning head being supported on the ground only by the at least one cleaning attachment when the handle body is in the inclined use position, a water tank being provided on either the cleaning head or the handle body, and a locking mechanism being provided between the cleaning head and the handle body for locking the handle body in the upright stop position; the cleaning head also... The device includes a rear support assembly for assisting in supporting the cleaning head when it is in the upright stop position. The rear support assembly includes a support member and a linkage mechanism. The support member can move up and down between a low position on the same plane as the at least one cleaning attachment and a high position above the plane where the at least one cleaning attachment is located. When the handle body is in the upright stop position, the cleaning head is supported on the ground by the at least one cleaning attachment and the support member in the low position. The linkage mechanism is connected to the support member and the lower part of the handle body so that when the handle body is rotated from the tilted use position to the upright stop position, the rotation of the handle body causes the support member to descend to the low position.

[0005] In the above technical solution, preferably, the supporting component includes a caster.

[0006] In the above technical solution, preferably, the linkage mechanism also satisfies the requirement of transmitting a force applied to the lower part of the handle body to the support member when the handle body is in the tilted use position, so that the support member is held in the high position. Further preferably, the linkage mechanism includes a rotating bracket, which is rotatably mounted on the housing about a second transverse axis. The rotating bracket includes a front end located in front of the second transverse axis and a rear end located behind the second transverse axis. A spring is provided between the rear end and the housing. The support member is mounted on the rear end. The lower part of the handle body has an abutment surface that abuts against the rear end when the handle body is in the tilted use position.

[0007] In the above preferred embodiment, it is further preferred that the contact surface applies a downward force to the rear end when the handle body is in the tilted use position.

[0008] In the preferred embodiment described above, and even more preferably, the lower part of the handle body includes a rotary joint, which is rotatably mounted on the housing about the first transverse axis, and the contact surface is located at the rotary joint.

[0009] In the above technical solution, preferably, the handle body includes a housing, a steam boiler disposed within the housing, and a water supply tank disposed on the housing.

[0010] In the above technical solution, preferably, the handle body includes a housing, a vacuum motor disposed in the housing, a dust cup assembly detachably disposed on the housing, and a handle assembly fixedly disposed on the upper part of the housing; the cleaning head includes at least one suction port located at the bottom of the housing, and the suction port, the dust cup assembly, and the vacuum motor are in sequential fluid communication.

[0011] In the above preferred embodiment, and more preferably, the water supply tank is located at the cleaning head.

[0012] In the preferred embodiment described above, it is further preferred that the lower part of the housing is rotatably connected to the rotary joint about a longitudinal axis perpendicular to the first transverse axis.

[0013] In the above technical solution, preferably, the at least one cleaning accessory includes a pair of rotatable cleaning discs, the pair of rotatable cleaning discs being symmetrically distributed left and right and defining a symmetrical axis extending front and back, and the support member being located on the symmetrical axis. Further preferably, the front boundary, left boundary, and right boundary of the cleaning head are all defined by the outer periphery of the pair of rotatable cleaning discs.

[0014] Compared to existing technologies, the cleaning mop provided by the present invention is equipped with a rear support component. The support member of the rear support component can be lowered to the same plane as the cleaning attachment when the handle body is in the stopped position to form a stable support, thereby improving the stability of the cleaning mop.

[0028] To explain in detail the technical content, structural features, achieved objectives and effects of this application, the technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings.

[0029] In this application, spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side” (e.g., as in a “sidewall”) are used to describe the relationship between one element and another element as shown in the accompanying drawings. Spatial relative terms are intended to include different orientations of the device in use, operation, and / or manufacture other than those depicted in the drawings. For example, if the device in the drawings is flipped, an element described as “below” or “under” another element or feature would then be positioned “above” said other element or feature. Thus, the exemplary term “below” can include both above and below orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0030] Based on the following facts and problems, this invention proposes a novel cleaning mop: Existing cleaning mops generally include a cleaning head that can move along the surface to be cleaned and a handle body that is rotatably connected to the cleaning head. The handle body has a tilted position for the user to push and pull the cleaning mop back and forth and a standing position for the user to store the cleaning mop.

[0031] The cleaning head is equipped with at least one cleaning component that can contact the surface to be cleaned to perform the cleaning operation. Depending on the type of cleaning mop, the cleaning component may vary. For example, a cleaning mop that uses wet cleaning may have a brush roller or brush disc as its cleaning component; while a cleaning mop that uses steam cleaning may have a rotating cleaning disc or cloth for wiping and contact with high-temperature steam on the surface to be cleaned.

[0032] A common problem with existing cleaning mops is that when the handle and body are in the upright, stopped position, the mop is only supported on a flat surface by the cleaning components, resulting in poor stability and frequent tipping. Therefore, this invention provides a cleaning mop with a rear support assembly that provides additional support when the handle and body are in the upright, stopped position. To illustrate the technical solution provided by this invention in detail, the following description uses a cleaning mop with a pair of rotating cleaning discs as cleaning attachments. However, it should be understood that the following technical solution can undoubtedly be applied to cleaning mops using other types of cleaning attachments; therefore, the specific type of cleaning attachment and the cleaning method of the mop do not limit the scope of protection of this invention.

[0033] Figure 1 The present invention provides a cleaning mop 100 that can move along a surface to be cleaned and perform cleaning operations using steam. As shown in the figure, the cleaning mop 100 includes a cleaning head 1 that can output steam and a handle body 2 that is rotatably connected to the cleaning head 1.

[0034] Combination Figure 2 and Figure 5 The cleaning head 1 is movable along the surface to be cleaned and includes a housing 11 forming an outer contour, a pair of rotatable cleaning discs 12 disposed at the bottom of the housing 11, a drive assembly for driving the pair of rotatable cleaning discs 12 to rotate, and a rear support assembly. The housing 11 is provided with a plurality of steam nozzles (not shown) for steam to flow out of the cleaning mop 100, and the steam nozzles are configured to face the surface to be cleaned and / or the pair of rotatable cleaning discs 12.

[0035] A pair of rotatable cleaning discs 12 are positioned to the left and right, defining a symmetrical axis Y1 that extends between them and passes through the center of the cleaning head 1. The pair of rotatable cleaning discs 12 are exposed, and their outer boundaries define the front, left, and right boundaries of the cleaning head 1, thereby enabling the cleaning mop 100 to effectively clean corners, table corners, and other hard-to-reach areas. The drive mechanism is located inside the housing 11 and includes a drive motor 13 as a power source and a synchronous gear set as a transmission component. The synchronous gear set is configured such that the drive motor 13 drives the pair of rotatable cleaning discs 12 to rotate in opposite directions.

[0036] The handle body 2 extends along a straight line and includes a handle assembly 21 at the top, a connecting end 23 at the bottom, and a main body 22 extending from the connecting end 23 to the handle 21. The handle assembly 21 is provided with a handle 211 suitable for one-handed operation and control buttons 212 provided on the handle 211, so that the user can operate the cleaning mop 100 with one hand.

[0037] The main body 22 includes a housing 221, a steam boiler 222 installed inside the housing 221, and a water tank 223 detachably installed on the housing 221. The handle assembly 21 is fixedly installed on the upper side of the housing 221; the water tank 223 is used to store and supply clean water, and the cleaning mop 100 forms a fluid output path from the water tank 223 to each steam nozzle on the cleaning head 1; the steam boiler 222 is located on the fluid output path and can convert the water from the water tank 223 into high-temperature steam for cleaning.

[0038] When the cleaning mop 100 is working, both the steam boiler 222 and the drive motor 13 are started; the clean water in the water supply tank 223 flows along the fluid output path and is converted into high-temperature steam at the steam boiler 222. The high-temperature steam is finally distributed to the surface to be cleaned and / or a pair of rotatable cleaning discs 12 through the steam nozzle of the cleaning head 1; finally, the rotating pair of rotatable cleaning discs 12 clean the wetted surface to be cleaned, thereby completing the cleaning operation.

[0039] The connecting end 23 is equipped with a rotary joint 231 fixedly connected to the lower part of the housing 221. The rotary joint 231 is rotatably connected to the housing 11 of the cleaning head 1 about a first transverse axis Y2. The handle body 2 has a use position that is tilted relative to the cleaning head 1 so that the user can push the cleaning mop 100, and a stop position that is upright relative to the cleaning head 1 so that the user can put the cleaning mop 100 away.

[0040] The lower part of the housing 221 is rotatably connected to the rotary joint 231 about a longitudinal axis Y4 perpendicular to the first transverse axis Y2, so that the handle body 2 has two degrees of freedom in the lateral and longitudinal directions relative to the cleaning head 1, making it easier for the user to operate the cleaning mop 100. Furthermore, the cleaning mop 100 is also equipped with a locking mechanism for locking the handle body 2 in a stopped position. This locking mechanism includes a retractable insert plate 224 relative to the housing 221 and a socket (not shown) on the upper surface of the housing 11 of the cleaning head 1. The locking mechanism is configured such that when the handle body 2 is in the stopped position, the socket is located directly below the insert plate 224 and can engage with the insert plate 224, thereby limiting the rotation of the handle body 2 in the lateral and longitudinal directions.

[0041] In other embodiments, the cleaning mop can also incorporate a solid waste collection function. Specifically, a vacuum motor for generating a suction flow and a dust cup assembly for separating solid waste and achieving gas-solid separation can be added to the handle body of the cleaning mop. The vacuum motor is located inside the housing, and the dust cup assembly is detachably mounted on the housing. Correspondingly, at least one suction port facing the surface to be cleaned is added to the cleaning head housing of the cleaning mop. The suction port, dust cup assembly, and vacuum motor are sequentially fluidly connected, forming a fluid path for the suction flow to flow from the surface to be cleaned to the vacuum motor, thereby collecting solid waste from the surface. In this embodiment, the cleaning mop can also have a water tank located on the cleaning head to simplify the structure of the handle body and lower the center of gravity of the cleaning mop.

[0042] See Figure 3 , Figure 6 and Figure 7 The rear support assembly is used to assist in supporting the cleaning mop 100 when the handle body is in the stopped position. The rear support assembly includes a liftable support member and a linkage mechanism that connects the rotary joint 231 to the support member.

[0043] The linkage mechanism includes a rotating bracket 141 and a spring 142 connected to the rotating bracket 141. The rotating bracket 141 is located on the axis of symmetry Y1 and is configured to be rotatably connected to the housing 11 of the cleaning head 1 about a second transverse axis Y3 parallel to the first transverse axis Y2. The rotating bracket 141 includes a pair of pivots (not shown) located on the second transverse axis Y3 and connected to the housing 11, and front and rear ends located on the front and rear sides of the second transverse axis Y3, respectively.

[0044] Spring 142 is located inside housing 11 and arranged at the rear end of rotating bracket 141. A force-bearing seat 143 adapted to spring 142 is disposed at the rear end of rotating bracket 141. The two ends of spring 142 are respectively fixedly connected to the inner side of the bottom end face of housing 11 and the lower end face of force-bearing seat 143. Spring 142 is configured to be in a stretched state to provide a downward force to force-bearing seat 143 (i.e., the rear end of rotating bracket 141).

[0045] The support member provided in this embodiment is a caster 15, which is fixedly connected to the rear end of the rotating bracket 141 and protrudes from the bottom of the cleaning head 1. The caster 15 is configured to have a low position coplanar with the pair of rotatable cleaning discs 12 and a high position above the low position. The low position is defined by the housing 11 of the cleaning head 1 (e.g., Figure 3 In other embodiments, the support member may also be a flexible component, a caster wheel, a smooth hemisphere, etc.

[0046] The rotary joint 231 is provided with a pair of pivot members 232 located on the first transverse axis Y2 and synchronously driven with the rotary joint 231. Each pivot member 232 includes an outwardly protruding limiting end (not shown in the figure) and an abutment surface 233 adjacent to the limiting end and facing rearward. The front section of the rotating bracket 141 includes a pair of abutment ends 144 respectively adapted to the pair of pivot members 232. The pair of pivot members 233 are configured such that when the handle body 2 is in the use position, the pair of abutment surfaces 233 contact the corresponding abutment ends 144 and apply a downward force (e.g., ...) to the front section of the rotating bracket 141. Figure 7 ); and a pair of abutment ends 144 that disengage from the rotating bracket 141 when the handle body 2 is in the stop position (e.g. Figure 6 ).

[0047] Understandably, when the handle body 2 is in the use position, a pair of abutment surfaces 233 and rotating brackets 141 provide a force that overcomes the tension of the spring 142 and raises the structure to a high position (i.e., detached from the surface to be cleaned), so that the user can push and pull the cleaning mop 100 to perform cleaning operations; when the handle body 2 is in the stop position, the rotating brackets 141, under the tension of the spring 142, lower the structure to a low position, and the structure and a pair of rotatable cleaning discs 12 form a stable support, thereby improving the stability of the cleaning mop 100.

[0048] The above embodiments are only for illustrating the technical concept and features of this application, and are intended to enable those skilled in the art to understand the content of this application and implement it accordingly. They should not be construed as limiting the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit of this application should be included within the scope of protection of this application.
