Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, specifically to cleaning equipment. Background Art

[0002] Taking a floor washer as an example, existing cleaning equipment usually includes a base, a body, and a handle. The base is close to the ground for cleaning work. The body is provided with a sewage tank, a clean water tank, a water pump, etc. The handle is for users to hold and operate. Users can push the floor washer by hand to clean the ground. However, since there are many low spaces in the household cleaning scenario, such as under the sofa, under the bed, etc., traditional cleaning equipment cannot lie flat during the cleaning process, and the body cannot lie flat on the ground, resulting in the cleaning equipment being unable to effectively clean low cleaning positions.

[0003] Currently, although there are floor washers on the market that can lie flat for cleaning and can clean low positions. However, when the floor washer lies flat to clean low positions, users need to squat down or bend down significantly to hold the handle and operate the floor washer, which is very inconvenient. Moreover, the actions of squatting and bending down are also prone to accidents, and the use experience is poor. Summary of the Utility Model

[0004] In view of this, the utility model provides a cleaning equipment to solve the problem that when the floor washer lies flat to clean low positions in the prior art, users need to squat down or bend down significantly during operation.

[0008] A handle assembly, including a handle main body and an extension part, and the extension part is detachably arranged between the body and the handle main body;

[0009] When the body is in the lying state, the extension part is installed between the body and the handle main body; when the body is in the standing state, the extension part is removed from the body and the handle main body, and the handle main body is directly connected to the body.

[0010] Beneficial effects: An extension component is detachably provided between the body and the handle main body. The extension component, as an accessory of the whole machine, can be disassembled. When it is desired to clean a low position, the extension component is added between the body and the handle main body, and then the body is lowered to a lying state by operating the handle assembly. The user can stand and operate the cleaning device normally. During the process of using the cleaning device in the lying state, the user does not need to bend down or squat, and can complete the cleaning of the low position, which is more convenient to use and has a better experience. When performing normal floor cleaning operations, the extension component can be removed, and the handle main body is directly installed on the body. The extension component is used as an accessory and does not need to be used. Therefore, by adopting a handle assembly with an addable extension component, the present application can not only achieve the technical effect that the user can normally stand and operate the lying cleaning device, which is convenient for cleaning low positions, effectively solving the problem that in the prior art, when the cleaning device lies flat to clean low positions, the user needs to squat or bend down significantly, but also when cleaning a large and narrow space such as under the bed, the length of the original handle may be insufficient, resulting in incomplete cleaning. By installing the extension component in the present application, the length of the entire handle can be increased, thereby enhancing the cleaning effect on low and narrow spaces and making the cleaning more thorough and in place.

[0078] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0079] The main components of cleaning equipment such as floor washers include a base, a body, and a handle. A sewage tank, a clean water tank, a vacuum motor, a water pump, etc. are arranged on the body. Its working principle is as follows: The water pump pumps the water in the clean water tank and sprays it onto the roller brush of the base to wet the roller brush, and the rotation of the roller brush is used to achieve the purpose of cleaning. The vacuum motor in the body generates suction, sucks the sewage through the sewage suction port on the base into the pipeline and sends it to the sewage tank, and the handle plays the role of pushing and pulling the base and human-machine interaction.

[0080] There are many low spaces in the household cleaning scenario, such as under the sofa, under the bed, etc. The traditional floor washer body cannot lie flat and cannot clean low positions. In the past two years, floor washers that can lie flat for cleaning have emerged in the industry. The body can lie flat at 180°, and low-position cleaning can be achieved. However, when cleaning low positions, users need to squat down or bend down significantly to flatten the body, and such cleaning actions are very laborious, and the actions of squatting and bending down are also prone to accidents, resulting in poor user experience.

[0081] Through the investigation of the user experience of the floor washer that can lie flat for cleaning, it is found that there is a problem that it is necessary to squat or bend down significantly when lying flat for cleaning low positions. The main reason for this problem is that the handle of the floor washer is rigidly connected to the body, and the length of the handle is designed for normal standing use. When the body lies flat to clean low positions, it is necessary to lower the handle close to the ground, and at this time, users need to squat down or bend down significantly to hold the handle and control the floor washer. Moreover, when cleaning a long and narrow space with a large area such as under the bed, the length of the original handle may not be enough, resulting in incomplete cleaning.

[0082] In order to solve the technical problems existing in the prior art that when using a floor washer that can be laid flat for cleaning, the user needs to squat or bend down significantly when cleaning low positions, and when cleaning a long and narrow space with a large area such as under the bed, the length of the original handle may not be sufficient, the embodiment of the present application adopts a handle assembly that can be equipped with an extension component, enabling the user to operate the floor washer in a normal standing position, facilitating the cleaning of low positions, and achieving a more thorough and in-place cleaning effect.

[0083] The following will describe the embodiments of the present utility model in conjunction with Figures 1 to 19 , to describe the embodiments of the present utility model.

[0084] According to an embodiment of the present utility model, on the one hand, the present utility model provides a cleaning device, including a base 10, a body 20, and a handle assembly 30. A cleaning assembly for cleaning a surface to be cleaned is provided on the base 10; the body 20 is movably connected to the base 10, and the body 20 can rotate around the base 10 to switch between a standing state and a lying state; the handle assembly 30 includes a handle main body 31 and an extension component 32, and the extension component 32 is detachably arranged between the body 20 and the handle main body 31; when the body 20 is in the lying state, the extension component 32 is installed between the body 20 and the handle main body 31; when the body 20 is in the standing state, the extension component 32 is removed from the body 20 and the handle main body 31, and the handle main body 31 is directly connected to the body 20.

[0085] In the above embodiment, through the extension component 32 detachably arranged between the body 20 and the handle main body 31, the extension component 32, as a whole machine accessory, can be disassembled. When wanting to clean a low position, the extension component 32 is installed between the body 20 and the handle main body 31, and then the body 20 is lowered to the lying state by operating the handle assembly 30. The user can use and operate the cleaning device in a normal standing position. During the process of using the cleaning device in the lying state, the user does not need to bend down or squat to complete the cleaning of the low position, which is more convenient to use and provides a better experience; when performing normal floor cleaning operations, the extension component 32 can be removed, and the handle main body 31 is directly installed on the body 20. The extension component 32, as an accessory, does not need to be used. Therefore, by adopting the handle assembly 30 that can be equipped with the extension component 32, the present application can not only achieve the technical effect that the user can operate the lying flat cleaning device in a normal standing position and facilitate the cleaning of low positions, effectively solving the problem that the user needs to squat or bend down significantly when the cleaning device lies flat to clean low positions in the prior art, but also when cleaning a long and narrow space with a large area such as under the bed, the length of the original handle may not be sufficient, resulting in incomplete cleaning. By installing the extension component 32 in the present application, the length of the entire handle can be increased, thereby enhancing the cleaning effect on low and long and narrow spaces, without cleaning dead corners, and achieving a more thorough and in-place cleaning.

[0086] It should be noted that the cleaning equipment provided in this embodiment includes, but is not limited to, floor washing machines, vacuum cleaners, integrated sweeping and mopping machines, electric mops, etc.

[0087] Preferably, the cleaning equipment provided in this embodiment is a floor washing machine.

[0088] Specifically, in this embodiment, the base 10 includes a housing and a cleaning component installed on the housing. The cleaning component includes a rolling brush and a rolling brush motor. The rolling brush is rotatably installed on the housing, and the rolling brush motor is fixedly installed on the housing to drive the rolling brush to rotate to achieve floor cleaning. A sewage suction port and a clean water outlet are provided on the base 10. The clean water outlet is arranged close to the rolling brush to facilitate the discharge of cleaning water for cleaning the floor. Wheels are also provided on the base 10 to facilitate pushing and pulling the floor cleaning device. The body 20 includes an installation main body, and a clean water tank, a sewage tank, a vacuum motor, a water pump, etc. are arranged on the installation main body. The sewage suction port is communicated with the vacuum motor and the sewage tank on the body 20 through a sewage suction pipeline, and the clean water outlet, the clean water tank, and the water pump are communicated through a water outlet pipeline. During the floor cleaning process, the water pump will spray the cleaning water in the clean water tank onto the floor through the clean water outlet. During the operation of the floor washing machine, cleaning water is discharged from the clean water outlet, and the rolling brush motor drives the rolling brush to rotate to clean the dirt on the floor, and then the vacuum motor provides suction to suck the cleaning dirt into the sewage tank through the sewage suction port.

[0089] In some embodiments, one end of the body 20 is hinged to the base 10, and the other end is detachably fixedly connected to the handle assembly 30. The body 20 can rotate around the base 10 to switch between a standing state and a lying state. When the body 20 is in the lying state, the body 20 is parallel to the surface to be cleaned; when the body 20 is in the standing state, the body 20 forms a set angle with the surface to be cleaned, where the set angle ≤ 90°.

[0090] In the above embodiment, when the body 20 is in the lying state, the body 20 is parallel to the surface to be cleaned, and the body 20 and the base 10 are on the same horizontal plane, so that the base 10 can extend into low narrow slit positions such as under the sofa and under the bed. When the body 20 is in the standing state, the body 20 forms a set angle with the surface to be cleaned, and the included angle is less than or equal to 90°, which is convenient for the user to push and pull and control the cleaning equipment.

[0091] In this embodiment, the handle assembly 30 includes a handle body 31 and an extension member 32. The extension member 32 has a set extension length, and the length of the extension member 32 is not less than the set length. The extension member 32 can adopt structural forms such as an extension rod 321, an extension connector, an extension tube, an extension bracket, etc., and this embodiment does not limit this. By detachably arranging the extension member 32 between the body 20 and the handle body 31, when the body 20 is in a lying state, the extension member 32 is added between the body 20 and the handle body 31, so as to increase the length of the entire handle assembly 30. The handle body 31 is at a high position, which is convenient for the user to stand and hold the handle body 31, and control the forward and backward movement and the twisting steering of the cleaning device through the handle body 31, without squatting or bending down significantly, and the use experience is better.

[0092] In some embodiments, a first mounting structure for mounting the extension member 32 is provided on the body 20, and a first connection structure detachably connected to the first mounting structure is provided at one end of the extension member 32; a second mounting structure for mounting the handle body 31 is provided at the other end of the extension member 32, and a second connection structure detachably connected to the second mounting structure is provided on the handle body 31; the first mounting structure and the second mounting structure have the same structure, so that the handle body 31 can be assembled and connected to any one of the extension member 32 and the body 20.

[0093] In the above embodiment, the extension member 32 and the body 20, the handle body 31 and the extension member 32, and the handle body 31 and the body 20 are all assembled and connected in a detachable connection manner, which is convenient for disassembly and assembly. The first mounting structure and the second mounting structure have the same structure, and the first connection structure and the second connection structure have the same structure. Since the part of the body 20 for mounting the extension member 32, the part of the extension member 32 for mounting the handle body 31, the part of the handle body 31 inserted into the body 20, and the part of the extension member 32 inserted into the body 20 are all the same, this can effectively ensure that after the extension member 32 is removed, the handle body 31 can be directly inserted into the body 20, and the operation is more convenient and fast, avoiding the problem of improper installation.

[0094] Specifically, in this embodiment, the extension member 32 and the body 20, the handle body 31 and the extension member 32, and the handle body 31 and the body 20 can be assembled by means of snap connection, screws, plug-in connection, etc. The first mounting structure and the first connection structure, the second mounting structure and the second connection structure are respectively a snap connection assembly structure, a screw assembly structure, and a plug-in connection assembly structure.

[0095] Preferably, the lengthening component 32 is assembled and fixed to the fuselage 20, the handle body 31 is assembled and fixed to the lengthening component 32, and the handle body 31 is assembled and fixed to the fuselage 20 by means of snap connection and / or plug connection. In this way, the user can disassemble and assemble the lengthening component 32 without the aid of external tools, which is more convenient and fast.

[0096] In some embodiments, the lengthening component 32 includes a lengthening rod 321 and a fuselage docking member 322. The lengthening rod 321 is hinged to the fuselage docking member 322, and the fuselage docking member 322 is detachably mounted on the fuselage 20.

[0097] In the above embodiments, the lengthening component 32 is designed with two parts, namely the lengthening rod 321 and the fuselage docking member 322. Among them, the lengthening rod 321 is hinged to the fuselage 20, and the fuselage docking member 322 is detachably mounted on the fixed fuselage 20. Through the above design, the lengthening component 32 can be quickly connected and fixed to the fuselage 20, facilitating the quick disassembly and assembly of the lengthening component 32. At the same time, the main part of the lengthening component 32 can rotate around the fuselage 20, enabling the user to flexibly adjust the angle between the lengthening rod 321 and the fuselage 20 according to actual usage needs, avoiding the problem of inconvenient operation caused by the rigid connection between the lengthening rod 321 and the fuselage 20.

[0098] Optionally, both the fuselage docking member 322 and the lengthening rod 321 are injection molded parts, which have low cost and light texture.

[0099] It should be noted that in the above embodiments, the fuselage docking member 322 can be detachably mounted and fixed on the fuselage 20 by means of snap connection and plug connection. The lengthening rod 321 is not limited to being connected to the fuselage docking member 322 by means of hinge connection. The lengthening rod 321 can also be connected to the fuselage docking member 322 by means of screws or snap connection.

[0101] In some embodiments, the fuselage docking member 322 includes a plugging part 3221 and a locking part 3222. A plugging cooperation part 21 is provided on the fuselage 20, and the plugging part 3221 is plugged into the plugging cooperation part 21; the locking part 3222 is provided on the plugging part 3221 and is used to lock or release the fuselage docking member 322. When the fuselage docking member 322 is in the locked state, the locking part 3222 is in limit cooperation with the fuselage 20; when the fuselage docking member 322 is in the released state, the locking part 3222 is disengaged from the fuselage 20.

[0102] In the above embodiments, the fuselage docking member 322 is provided with a plugging portion 3221 and a locking portion 3222. The plugging portion 3221 can be plugged into the plugging and mating portion 21 of the fuselage 20, and the locking portion 3222 can be in limit cooperation with the fuselage 20 to lock the fuselage docking member 322, preventing the plugging portion 3221 from disengaging from the plugging and mating portion 21, improving the stability and reliability of the cooperation between the fuselage docking member 322 and the fuselage 20. Moreover, the locking portion 3222 can also disengage from the limit cooperation with the fuselage 20 under the action of an external force to release the fuselage docking member 322, enabling the lengthening member 32 to be quickly removed from the fuselage 20. The setting of the locking portion 3222 can further improve the convenience of disassembling and assembling the lengthening member 32.

[0103] In some embodiments, the plugging portion 3221 includes a plugging rod, and the plugging and mating portion 21 includes a plugging cylinder that cooperates with the plugging rod; the locking portion 3222 includes a disassembly button provided on the plugging rod, and a button opening 211 corresponding to the disassembly button is provided on the plugging cylinder; the disassembly button is normally limited in the button opening 211 and protrudes from the button opening 211 when acted upon by an external force.

[0104] In the above embodiments, when the fuselage docking member 322 is installed in place, the disassembly button can just be located in the button opening 211 of the fuselage 20. When it is necessary to disassemble the lengthening member 32, the disassembly button is pressed, so that the disassembly button disengages from the button opening 211 to unlock, and then the fuselage docking member 322 is pulled out from the plugging and mating portion 21 of the fuselage 20, and the quick disassembly of the lengthening member 32 from the fuselage 20 can be realized. By adopting the structural form of the disassembly button and the button opening 211 to lock the lengthening member 32 and the fuselage 20, not only is the structure simple and the locking effect good, but also the unlocking operation is very convenient and fast.

[0105] In some more specific implementation manners, the plugging rod is a hollow rod-shaped structure, and the plugging rod is made of a deformable plastic part. The disassembly button is fixedly arranged on the outer wall of the plugging rod. Preferably, the disassembly button and the plugging rod are integrally injection-molded. When the user presses the disassembly button, the hollow plugging rod can deform inward in the area corresponding to the disassembly button, facilitating pressing for unlocking.

[0106] Preferably, as Figure 8 、 Figure 12 、 Figure 13 shown, a deformation opening 32210 is provided on the peripheral wall of the plugging rod corresponding to the setting area of the disassembly button. Through the provided deformation opening 32210, when the disassembly button is subjected to an external pressure, the peripheral wall of the plugging rod is more likely to deform inward, so that the disassembly button can more easily disengage from the button opening 211.

[0107] More preferably, the deformation opening 32210 is a strip-shaped opening extending along the length direction of the plug-in rod, and there are two deformation openings 32210 , which are distributed on both sides of the disassembly button.

[0108] In other alternative embodiments, the disassembly button can also be configured to be elastically retractable. When not subject to external force, the disassembly button can extend into the button opening 211 under the action of its own elastic force to achieve locking; when subjected to external pressure, the disassembly button can shrink inward and escape from the button opening 211.

[0109] In some preferred embodiments, Figure 8 , Figure 12 As shown, the disassembly button is provided with an inclined guide surface 32220, and the distance between the inclined guide surface 32220 and the outer wall of the plug rod gradually increases along the insertion direction of the fuselage docking piece 322. Preferably, the lower end side of the inclined guide surface 32220 is directly connected to the outer wall of the plug rod. By providing the inclined guide surface 32220, it is possible to effectively prevent the disassembly button from getting stuck between the fuselage 20 during the process of inserting the fuselage docking piece 322 into the fuselage 20.

[0110] In some embodiments, the fuselage docking piece 322 also includes an anti-foolproofing portion 3223 and an anti-foolproofing mating portion 212, the anti-foolproofing portion 3223 is arranged on the outer wall of the plug-in portion 3221; the anti-foolproofing mating portion 212 is arranged on the plug-in mating portion 21, and the anti-foolproofing portion 3223 is positioned and matched with the anti-foolproofing mating portion 212 so that the fuselage docking piece 322 can be installed into the fuselage 20 along a preset installation direction.

[0111] In the above embodiment, by setting the anti-foolproof part 3223 and the anti-foolproof matching part 212, when the installation direction is wrong, the fuselage docking part 322 cannot be installed into the fuselage 20, so that the fuselage docking part 322 can be installed along the preset installation direction, thereby improving the assembly efficiency and avoiding the problem of the fuselage docking part 322 being installed in the wrong direction and affecting the assembly efficiency.

[0112] Optionally, one of the foolproofing part 3223 and the foolproofing matching part 212 is a convex rib, and the other is a groove. Preferably, the foolproofing part 3223 is a foolproofing rib, and the foolproofing matching part 212 is a matching groove. The foolproofing rib is a strip rib whose extension direction is consistent with the length direction of the plug rod, and the matching groove is a strip groove correspondingly arranged on the inner wall of the plug tube. The foolproofing rib can effectively prevent the fuselage docking piece 322 from being installed in the wrong direction. The installation part of the fuselage 20 is provided with a matching groove that cooperates with the foolproofing rib. When the installation direction is wrong, the fuselage docking piece 322 cannot be installed.

[0113] In some embodiments, the fuselage docking member 322 further includes a limiting portion 3224. The limiting portion 3224 is fixedly arranged on the side of the insertion portion 3221 close to the extension rod 321. The limiting portion 3224 is used for anti-blocking cooperation with the insertion and cooperation portion 21 to limit the insertion depth of the insertion portion 3221.

[0114] In the above embodiment, through the limiting portion 3224 arranged at the end of the insertion portion 3221, during the process of inserting the fuselage docking member into the fuselage 20, when the fuselage docking member is installed in place, the limiting portion 3224 can be in anti-blocking cooperation with the insertion and cooperation portion 21 to limit the insertion depth of the insertion portion 3221 and prevent the problem that the excessive insertion of the insertion portion 3221 affects the assembly. In addition, as Figure 15 shown, the arranged limiting portion 3224 can also play a role in limiting the maximum bending angle of the extension rod 321 and prevent the problem that the excessive rotation of the extension rod 321 affects the normal use.

[0115] Optionally, the limiting portion 3224 includes a limiting plate fixedly arranged on the outer wall of the insertion portion 3221. The extending direction of the limiting plate is perpendicular to the insertion and extraction direction of the insertion portion 3221. When the insertion portion 3221 is inserted in place, the limiting plate can abut against the edge of the end of the insertion and cooperation portion 21 to play a role in limiting and preventing the excessive insertion of the insertion portion 3221.

[0116] In some embodiments, the fuselage docking member 322 further includes a hinge portion 3225. The hinge portion 3225 is fixedly arranged at one end of the insertion portion 3221 close to the extension rod 321; one end of the extension rod 321 is provided with a hinge seat 32111 cooperating with the hinge portion 3225. The hinge portion 3225 and the hinge seat 32111 are connected by a rotating shaft.

[0117] In the above embodiment, through the arrangement of the hinge portion 3225 on the fuselage docking member 322 and the arrangement of the hinge seat 32111 on the extension rod 321, when assembling, the rotating shaft is used to connect the hinge portion 3225 and the hinge seat 32111 in sequence, that is, the hinge of the fuselage docking member 322 and the extension rod 321 can be realized, which is very convenient and fast.

[0118] Specifically, the hinge seat 32111 includes two relatively arranged hinge plates. An installation space for accommodating the hinge portion 3225 is formed between the two hinge plates. The hinge portion 3225 is provided with a first shaft hole, and the two hinge plates are respectively provided with second shaft holes. When assembling, the hinge portion 3225 is placed in the hinge seat 32111 and the corresponding positions are aligned, and then the rotating shaft passes through the hinge seat 32111 and the hinge portion 3225 in sequence, and the connection between the fuselage docking member 322 and the extension rod 321 can be realized.

[0119] Further, as Figures 7 to 9 、 Figure 12 、Figure 15 As shown, the limiting portion 3224 is located at one end of the insertion portion 3221 close to the hinge portion 3225. The opposite side walls of the limiting portion 3224 are respectively a first limiting surface and a second limiting surface. Specifically, the side wall of the limiting portion 3224 away from the hinge portion 3225 is the first limiting surface, and the side wall close to the hinge portion 3225 is the second limiting surface. Among them, the first limiting surface is used to cooperate with the insertion and mating portion 21 in a stop manner during the process of the fuselage docking member 322 being inserted into the fuselage to prevent the insertion portion 3221 from being inserted excessively, and the second limiting surface is used to limit the maximum bending angle of the extension rod 321 during the process of rotating the extension rod 321 to prevent the extension rod 321 from rotating excessively.

[0120] In some embodiments, such as Figures 6 to 9 、 Figure 14 、 Figure 15 As shown, the hinge portion 3225 includes a cylindrical hinge body 32251 and a limiting rib 32252 provided on the outer peripheral wall of the hinge body 32251; an arc-shaped rotating wall 32110 is provided in the hinge seat 32111. The arc-shaped rotating wall 32110 is located on the outer peripheral side of the hinge body 32251 and can rotate around the central axis of the hinge body 32251 along with the extension rod 321; during the process of the arc-shaped rotating wall 32110 rotating around the hinge body 32251, the limiting rib 32252 can cooperate with the end of the arc-shaped rotating wall 32110 in a stop manner to limit the rotation angle of the extension rod 321 within a set angle range.

[0121] In the above embodiments, by providing the limiting rib 32252 on the outer peripheral wall of the cylindrical hinge body 32251 and the arc-shaped rotating wall 32110 fixedly provided in the hinge seat 32111, the arc-shaped rotating wall 32110 is located on the outer peripheral side of the hinge body 32251, and the radian of the arc-shaped rotating wall 32110 matches the radian of the outer peripheral wall of the hinge body 32251. During the rotation of the extension rod 321, the arc-shaped rotating wall 32110 can rotate around the hinge body 32251 accordingly and can cooperate with the limiting rib 32252 in a stop manner, so as to achieve the purpose of limiting the rotation angle of the extension rod 321 within a set angle range and avoid the problem that the degree of freedom of the extension rod 321 is too high and it is inconvenient for the user to operate.

[0122] Specifically, the limiting rib 32252 is an arc-shaped rib fixedly provided on the outer peripheral wall of the hinge body 32251. Preferably, the limiting rib 32252 is integrally formed with the hinge body 32251. During the rotation of the extension rod 321, the two end walls of the arc-shaped rib can abut against the ends of the corresponding side arc-shaped rotating wall 32110, thereby limiting the rotation angle of the extension rod 321 within a set angle range.

[0123] Preferably, the set angle range is 0 to 90°, such asFigure 14 As shown, at 0°, the extension rod 321 and the fuselage docking part are in the same plane, facilitating the extension rod 321 to extend into the low and narrow cleaning position along with the base 10 and the fuselage 20; as Figure 15 shown, at 90°, the extension rod 321 is perpendicular to the fuselage docking part. The bottom wall of the arc-shaped rib near the ground side is configured as a plane, facilitating the extension component 32 to fit on the ground. The arc-shaped rib is wrapped around one side of the hinged body 32251 near the insertion part 3221. The end wall of the arc-shaped rib near the ground side is perpendicular to the length direction of the insertion part 3221, and the end wall far from the ground side is parallel to the length direction of the insertion part 3221.

[0124] In this embodiment, the mating part between the fuselage docking part and the extension rod 321 includes a substantially circular hinged body 32251. After the extension rod 321 is installed, it can rotate 0 to 90° around the central axis of the hinged body 32251. The state of the extension rod 321 before rotation after assembly is as Figure 14 shown, and the state after rotating 90° around the central axis is as Figure 15 shown. When it is necessary to clean a low position, the extension component 32 is added to the fuselage 20. As Figure 1 shown, one end of the extension component 32 is installed on the fuselage 20, and the handle main body 31 is installed on the other end. There is a certain angle between the fuselage docking part 322 and the extension rod 321. Therefore, the height of the handheld part of the handle main body 31 can change with the change of the angle between the fuselage docking part 322 and the extension rod 321. When cleaning a low area, people do not need to bend down or squat, which is more convenient to use. After cleaning the low area, the extension component 32 can be disassembled as an accessory.

[0125] In an alternative embodiment, the extension rod 321 includes a rod main body, and the rod main body includes a first rod body 3211 and a second rod body 3212 buckled on the side of the first rod body 3211. The first rod body 3211 and the second rod body 3212 are detachably connected; a hinge seat 32111 is arranged at one end of the first rod body 3211 for connecting with the fuselage docking part 322; the extension rod 321 includes a handle mounting part 32112, and the handle mounting part 32112 is arranged at the other end of the first rod body 3211 for mounting the handle main body 31.

[0126] In the above embodiment, the rod main body of the extension rod 321 adopts a first rod body 3211 and a second rod body 3212 that are arranged in half. After the first rod body 3211 and the second rod body 3212 are respectively processed and formed, they are assembled to form the main body part of the circumferentially closed extension rod 321. The design of the two parts is more convenient for demolding and processing and forming compared with the integral molding method, effectively solving the problems of difficult injection molding and inconvenient processing and manufacturing when the first rod body 3211 and the second rod body 3212 are integrally arranged.

[0127] In the above embodiments, the first rod body 3211 and the second rod body 3212 can be fixed by screws and / or snap fasteners. After being connected, the first rod body 3211 and the second rod body 3212 can form an elongated rod 321 with a hollow interior.

[0128] Optionally, the first rod body 3211 and the second rod body 3212 are snap-connected to each other and fixed by screws. A plurality of screw posts are arranged at intervals along the length direction inside the first rod body 3211, and a plurality of screw holes are correspondingly arranged on the second rod body 3212. The connection and fixation of the first rod body 3211 and the second rod body 3212 are realized by connecting the plurality of screw holes and the plurality of screw posts with a plurality of screws respectively.

[0129] Optionally, a number of reinforcing ribs are arranged inside the first rod body 3211 and the second rod body 3212 to increase the structural strength of the elongated rod 321.

[0130] Optionally, the hinge seat 32111 and the handle mounting portion 32112 are integrally formed with the first rod body 3211. The handle mounting portion 32112 has the same shape and structure as the plug-in mating portion 21. A handle connection portion 311 that is plug-in mated with the handle mounting portion 32112 is arranged on the handle main body 31. The handle connection portion 311 has the same shape and structure as the plug-in portion 3221, and structures such as a disassembly button and an anti-fooling rib are also arranged on the handle connection portion 311. For the specific structure of the handle connection portion 311, reference can be made to the part where the body docking member 322 cooperates with the body 20, which will not be elaborated herein in this embodiment.

[0131] Next, with reference to the accompanying drawings, the specific structure and working principle of the floor cleaning device provided in this embodiment will be introduced.

[0132] In this embodiment, the lengthening component 32 is composed of two parts, an elongated rod 321 and a body docking member 322. The elongated rod 321 includes a first rod body 3211 and a second rod body 3212 that are detachably connected. The body docking member 322 includes a plug-in portion 3221 that is inserted into the body 20, a locking portion 3222 for locking the body docking member 322, a hinge portion 3225 that cooperates with the elongated rod 321, an anti-fooling portion 3223, and a limiting portion 3224, as shown in Figures 7 to 9 shown. The hinge portion 3225 of the body docking member 322 is generally circular. After the elongated rod 321 is installed, it can rotate around a rotating shaft connected between the hinge portion 3225 and the hinge seat 32111 within 0 to 90°. Figure 14 For the state of the elongated rod 321 after assembly and before rotation, as shown in the figure, when it rotates 90° around the rotating shaft, the state is as shown in Figure 15 shown. As shown in Figure 8 , Figure 10 , Figure 11As shown, the anti-fooling rib is mainly used to prevent incorrect installation directions. There is a mating groove on the installation part of the fuselage 20 that mates with the anti-fooling rib. When the installation direction is incorrect, it cannot be inserted.

[0133] Further, as Figure 12 shown, the fuselage docking part 322 is installed into the fuselage 20. After being installed in place, the disassembly button is just located in the button opening 211 of the fuselage 20. When disassembly is required, press the disassembly button inward, and the disassembly button deforms inward to Figure 13 the state shown. At this time, the fuselage docking part 322 can be pulled outwards.

[0134] Further, the structure of the extension rod 321 is as Figures 3 to 6 、 Figure 16 、 Figure 17 shown. One end is a mating end that mates with the fuselage docking part 322 and is installed on the fuselage docking part 322. It can be connected to the fuselage docking part 322 by screws or hinges. The other end of the extension rod 321 is a docking end with the handle, and the handle body 31 is installed at this end. After installation, it is as Figure 18 shown. The disassembly and assembly method of the handle body 31 is the same as that of the fuselage docking part 322. The second rod body 3212 is detachably installed on the first rod body 3211, mainly playing the role of facilitating the processing and manufacturing of the extension rod 321. When the first rod body 3211 and the second rod body 3212 are integrated, injection molding is difficult and inconvenient for manufacturing. Therefore, they are divided into two parts for separate processing and then assembled, which is more convenient for processing and forming. The second rod body 3212 can be fixed to the first rod body 3211 by screws, buckles or other means.

[0135] As Figure 2 shown, when normal cleaning is carried out, the handle body 31 is directly installed on the fuselage 20, and the extension part 32 is used as an accessory and does not need to be used. When cleaning low positions is required, the extension part 32 is added to the fuselage 20. As Figure 1 shown, one end of the extension part 32 is installed on the fuselage 20, and the handle body 31 is installed at the other end. There is a set angle between the fuselage docking part 322 and the extension rod 321. Therefore, the height of the handheld part of the handle body 31 can change with the change of the angle. When cleaning low and narrow areas, people do not need to bend down or squat, which is more convenient to use and effectively solves the problem that people need to bend down when the equipment lies flat for cleaning. After cleaning the low area, the extension part 32 can be removed as an accessory. In this embodiment, the extension part 32 is used as an accessory of the whole machine and can be disassembled and installed. When the cleaning equipment cleans the low area, users do not need to bend down or squat to complete the cleaning of low positions.

[0136] Although embodiments of the present utility model are described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations fall within the protection scope of the embodiments of this application.
