Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a connecting rod assembly and a floor scrubber. Background Art

[0002] Early floor cleaning tools included brooms, mops, and floor scrubbers, all of which relied primarily on manual operation. With technological advancements, demands for floor cleaning tools gradually increased. The first to emerge were vacuum cleaners, which rely on electricity to generate negative pressure to suck up trash and dust from the floor. Based on the cleaning method and the pathways through which small and large particles of waste are removed, this type of technology is often categorized as air-dust circulation. However, due to the limitations of their operating principle, vacuum cleaners are unable to remove some debris and stains firmly adhered to the floor. Consequently, new "water-dust circulation" floor scrubbers have emerged. These scrubbers use a motor to drive a cleaning cylinder to wipe the floor. These floor scrubbers are also equipped with a water supply system and sink to clean the cylinder, achieving perfect floor cleaning.

[0003] The applicant's patent CN220175029U discloses a connecting rod for a floor scrubber, comprising a hollow rod body, an upper connecting assembly and a lower connecting assembly, and also comprising an upper connecting shell and a lower connecting shell. The upper end of the upper connecting shell is fixedly connected to the handle of the floor scrubber, and the lower end of the lower connecting shell is fixedly connected to the mop head of the floor scrubber. Limiting grooves are provided on the upper and lower side walls of the rod body. When the upper and lower ends of the rod body are respectively inserted into the upper connecting shell and the lower connecting shell, the upper connecting shell and the lower connecting shell respectively extend into the upper and lower ports of the rod body. The upper connecting assembly, the upper connecting shell, the lower connecting assembly and the lower connecting shell correspond to each other, so that the upper and lower ends of the rod body are respectively firmly connected to the handle of the floor scrubber and the mop head.

[0004] The applicant's patents CN222149940U, CN118592856A, CN118370493A, CN118340476A, and CN118592857A disclose a floor scrubber connecting rod and a floor scrubber. The connecting rod includes a hinge assembly, a connecting rod assembly, a handle assembly, and a connecting assembly. The connecting rod assembly includes a first connecting rod assembly and a second connecting rod assembly. The first connecting rod assembly is provided with a water pump. The connecting assembly includes a first connecting assembly and a second connecting assembly. The first connecting assembly is used to connect one end of the first connecting rod assembly to the hinge assembly. The first connecting assembly accommodates a circuit connecting the water pump and the hinge assembly and a circulating water path. The second connecting assembly is used to connect the other end of the first connecting rod assembly to one end of the second connecting rod assembly. The other end of the second connecting rod assembly is connected to the handle assembly. The second connecting assembly accommodates a circuit channel connecting the water pump and the handle assembly. The present invention solves the problem of external damage to the connecting rod circuit components, water path, and circuit when the floor scrubber is removed and placed in the water tank or the body is maintained, while reducing the volume.

[0005] In the embodiments of the applicant's patent series, the battery pack and control panel are both located within the first connecting rod assembly, which is connected between the second connecting rod assembly and the hinge assembly. To ensure reliable connections between the hinge assembly, the first connecting rod assembly, and the second connecting rod assembly during daily use, the two clamping joints are very tight, making them difficult to disassemble. When the floor scrubber malfunctions after a period of use, the fault is often due to the battery or control panel within the first connecting rod assembly. At this point, the first connecting rod assembly, which is sandwiched between the two, needs to be disassembled. This disassembly process greatly inconveniences the user in terms of maintenance and often leads to customer complaints. In the prior art, even if a floor scrubber with a removable connecting rod assembly is available, it still cannot solve the problem of different heights among different users in a household, resulting in different length requirements for the floor scrubber's connecting rod assembly. In the prior art, the holding height of the floor scrubber is changed by replacing the "extended version" or "shortened version" of the first connecting rod assembly and / or the second connecting rod assembly. On the one hand, the repeated disassembly and assembly process is very troublesome. On the other hand, the daily usage data is recorded in the "control panel" installed in the first connecting rod assembly or the second connecting rod assembly. Frequent replacement of the first connecting rod assembly and / or the second connecting rod assembly will also cause the user usage habit data recorded and stored in different "control panels" to be inconsistent and inconsistent, which is not conducive to the collection and statistics of user data by the floor scrubber manufacturer. Moreover, the floor scrubber must be shut down during the replacement of the first connecting rod assembly and / or the second connecting rod assembly, which brings trouble to the user.

[0006] Therefore, it is necessary to further improve and optimize the connecting rod of the "water-dust circulation" floor scrubber to facilitate users to quickly disassemble the parts that need to be replaced directly and improve the convenience of disassembling faulty components.

On the other hand, the present application can also solve the problem of having to arduously disassemble the upper and lower rod assemblies when a floor scrubber malfunctions, and repeatedly returning the two assemblies to the factory for repair and replacement, which is time-consuming and expensive. A floor scrubber equipped with the connecting rod assembly of the present application can announce the specific fault point through the voice module on the handle, and then accurately disassemble the entire connecting rod assembly and replace the entire faulty connecting rod assembly as a whole for maintenance, reducing the number of times users disassemble and assemble the connecting rod assembly and the number of times they repeatedly transport spare parts back and forth, thereby improving the user experience.

[0060] First, as Figure 1-8As shown, the present invention provides a connecting rod assembly 10 for a floor scrubber, the connecting rod assembly is detachably connected to a handle 50 and a hinge device 20 hinged to a mop head 30, the floor scrubber is provided with at least one water pump, and the mop head 30 is provided with a drive motor (not shown in the drawings) capable of driving a cleaning roller (not shown in the drawings) to rotate and scrub the floor, the connecting rod assembly includes a lower rod assembly 10A, an upper rod assembly 10B, and an adjustment mechanism 10C connecting the lower rod assembly 10A and the upper rod assembly 10B; the upper rod assembly 10B includes an upper rod housing 100b, an upper rod housing 100b, and an upper rod housing 100c. Component 10B is detachably connected to the handle 50 in mechanical and electrical connection; the lower rod component 10A can be quickly docked with the hinge device 20, and the lower rod component 10A includes a lower rod housing 100a, and the lower rod component 10A and the hinge device 20 can achieve synchronous mechanical connection, electrical connection, and water connection in a single operation; the lower end of the upper rod housing 100b is sleeved on the outside or inside of the upper end of the lower rod housing 100a; the adjustment mechanism 10C can allow the upper rod housing 100b and the lower rod housing 100a to be in a relatively sliding state or a locked state; the connecting rod component 10 also includes a first bracket 100A, which can be installed in any one of the lower rod housing 100a and the upper rod housing 100b, or the first bracket 100A can be installed between the lower rod housing 100a and the upper rod housing 100b; a control board 110 can be installed on the first bracket 100A, and the control board 110 is electrically connected to the hinge device 20 and the handle 50 and is electrically connected to the tractor 30 through the hinge device 20; when working, the upper rod assembly 10B maintains mechanical and electrical connection with the lower rod assembly 10A, and the upper rod assembly 10B maintains a mechanical and electrical connection with the handle 50, and the lower rod assembly 10A maintains a mechanical, electrical, and water connection with the hinge assembly 20. The hinge assembly 20 is hingedly connected to the mop head 30. The control board 110 within the connecting rod assembly 10 controls the operation of the drive motor within the mop head 30 under the power of the battery pack 120, thereby controlling the drive motor to drive the cleaning roller to rotate and mop the floor. At the same time, the control board 110 also controls the water pump to intermittently spray water onto the surface of the cleaning roller. The wetted surface of the cleaning roller is continuously cleaned and mopped. When the user needs to adjust the length of the connecting rod assembly 10, the upper rod assembly 10B and the lower rod assembly 10C remain electrically connected. The user can adjust the length of the connecting rod assembly 10 at will without turning off the floor scrubber, thereby improving the user's efficiency in using the washing machine.

[0061] Specifically, such as Figures 1 to 8As shown, a connecting rod assembly 10 of the present invention is used for a floor scrubber with a tractor head 30. One end of the connecting rod assembly 10 is connected to a hinge device 20, which is hinged to the tractor head 30. The other end of the connecting rod assembly 10 is connected to a handle 50. The hinge device 20 includes a connecting head (not shown in the drawings) and an articulated head (not shown in the drawings), which is articulated to the tractor head 30. The handle 50 is away from the tractor head 30, and the handle 50 has a clamping portion (not shown in the drawings) and a gripping portion (not shown in the drawings). The connecting rod assembly 10 is detachably connected between the hinge device 20 and the handle 50. 0 is provided with a water pump 101, and the connecting rod assembly 10 includes a lower rod assembly 10A and an upper rod assembly 10B; wherein, the hinge device 20 and the lower rod assembly 10A, and the upper rod assembly 10B and the handle 50 can be quickly docked; the water channels built into the tractor head 30, the hinge device 20 and the connecting rod assembly 10 are synchronously docked when the hinge device 20 and the lower rod assembly 10A are docked; the circuit circuits built into the tractor head 30, the hinge device 20, the connecting rod assembly 10 and the handle 50 (not shown in the drawings) are synchronously docked when the hinge device 20, the connecting rod assembly 10 and the handle 50 are docked.

[0062] More specifically, Figure 1-8 As shown, the adjustment mechanism 10C connects the upper rod assembly 10B and the lower rod assembly 10A into a single, non-detachable unit, forming the connecting rod assembly 10. The lower rod housing 100a is hollow, forming a cavity, and has an upper open end (not shown) and a lower open end (not shown). The first bracket 100A can be installed into the lower rod housing 100a or the upper rod housing 100b from either end. During maintenance, the first bracket 100A can be removed from either end of the lower rod housing 100a or the upper rod housing 100b. The upper rod housing 100b is hollow, forming a cavity, and has a second upper open end (not shown) and a second lower open end (not shown). The second upper open end is connected to the handle 50. The control panel 110 is electrically connected to the battery pack 120 of the floor scrubber, the water pump 101, and the drive motor in the tractor head 30 that drives the cleaning roller to rotate. The water pump is provided with a water outlet 101a and a water inlet 101b. The water outlet 101a and the water inlet 101b are respectively provided with a water outlet pipe (not marked in the drawing) and a water inlet pipe (not marked in the drawing).

[0063] In one or more optional embodiments, the hinge device 20 includes a connector and a hinge head. The connector end of the hinge device 20 is provided with a connecting terminal (not shown in the drawings), which is provided with a connecting terminal and a water inlet and outlet interface (not shown in the drawings). The lower end of the connecting rod assembly 10 is sleeved onto the connector of the hinge device 20. In this way, the connecting rod assembly and the hinge device can be detachably connected to each other, making the connection between the hinge device and the connecting rod assembly more convenient. At the same time, through a single quick docking of the connecting rod assembly and the hinge device, the mechanical connection, electrical connection, and water connection of the connecting rod assembly and the hinge device can be completed, which is efficient and convenient.

[0064] The connecting rod assembly of the present invention is used for a floor scrubber. By connecting and fixing the hinge device and the handle to each other, and hingedly connecting the hinge device to the mop head, the power supply, circuit, water channel and control panel are integrated and installed inside the connecting rod assembly, thereby reducing the overall volume of the floor scrubber and improving the protection of the internal components of the floor scrubber and the convenience of installation and disassembly; at the same time, the connecting rod assembly includes a lower rod assembly and an upper rod assembly with adjustable total length to solve the problem of different heights of different users in a family causing different length requirements for the connecting rod assembly of the floor scrubber. The connection channel between the connecting rod assembly and the hinge device contains the circuit line and the water channel connecting the water pump and the hinge device; and unlike the connection between the connecting rod assembly and the hinge device, the connection channel between the connecting rod assembly and the handle only contains the circuit channel connecting the water pump, the control panel and the handle. During installation, the user can correctly match the hinge device, the connecting rod assembly and the handle by distinguishing whether the connecting rod assembly is connected to the water and circuit dual-circuit of the hinge device, or the end of the connecting rod assembly is only connected to the circuit of the handle, thereby avoiding the problem of incorrect installation between the various components and improving the installation efficiency of the equipment. On the other hand, the present application can also solve the problem of the upper rod assembly and the lower rod assembly needing to be disassembled with great difficulty when the floor scrubber malfunctions, and the problem of repeatedly returning the two components to the factory for repair and replacement is time-consuming and costly. A floor scrubber equipped with the connecting rod assembly of the present application can broadcast the specific fault point through the voice module on the handle, and then accurately remove the entire connecting rod assembly, and replace and maintain the entire faulty connecting rod assembly as a whole, reducing the number of times the user disassembles and assembles the connecting rod assembly and the number of repeated round-trip transportation of spare parts, thereby improving the user experience. The connecting rod assembly solves the problem of inconvenient disassembly and maintenance of the connecting rod of the floor scrubber in the prior art.

[0065] In one or more optional embodiments, as Figure 3 、 Figure 4As shown, the battery pack 120 can also be mounted on the first bracket 100A. A lower port (not shown) is provided at one end of the first bracket 100A, facing the connector (not shown) of the hinge assembly 20. An upper port (not shown) is provided at the other end of the first bracket 100A. A first terminal harness 105 is connected to the control board 110. The first terminal harness 105 is electrically connected to the water pump 101. One end of the first terminal harness 105 passes through the lower port to be electrically connected to the connector, and the other end passes through the upper port to be electrically connected to the handle 50.

[0066] Specifically, such as Figure 3 、 Figure 4 As shown, a lower docking terminal 105c is provided at one end of the first terminal harness 105; the lower docking terminal 105c passes through the lower port of the first bracket 100A and the lower open end of the lower rod housing 100a in sequence, and is electrically connected to the connector of the hinge device 20. An upper docking terminal 105d is provided at the other end of the first terminal harness 105; the upper docking terminal 105d passes through the upper port of the first bracket 100A and the upper open end of the upper rod housing 100b in sequence, and is electrically connected to the handle 50. The first terminal harness 105 can automatically adjust its length as the upper rod housing 100b slides relative to the lower rod housing 100a. During the process of adjusting the length of the connecting rod assembly 10, all electrical connection points of the first terminal harness 105 remain electrically connected, which does not affect the operation of the floor scrubber. The middle section of the first terminal harness 105 is a spring-shaped spiral coil.

[0067] Mounting both the control board and battery pack on the first bracket allows the control board to access a nearby power source, reducing the risk of malfunctions caused by electrical connection failures between the power supply and the control board. The control board is the core of the scrubber's control system, determining fault points. Ensuring stable power to the control board ensures the scrubber's control system operates stably. The first terminal harness, which automatically adjusts in length as the connecting rod assembly length changes, ensures reliable electrical connection at all electrical connection points of the first terminal harness without shutting down the machine to adjust the length of the connecting rod assembly. The scrubber's grip height can be adjusted to accommodate users of different heights without shutting down the machine, improving its efficiency in scenarios where multiple people are using the scrubber.

[0068] In one or more optional embodiments, as Figure 3 、 Figure 4As shown, the control board 110 is threadedly connected to the fixing nut column (not marked in the drawings) of the first bracket 100A. The control board 110 is provided with an electrode sheet group (not marked in the drawings). The electrode sheet group clamps the battery pack 120. The first bracket 100A and the control board 110 jointly fix the battery pack 120. The control board 110 is electrically connected to the drive motor in the tractor head 30 to control the drive motor to drive the cleaning roller to rotate and wipe the floor. The water pump 101 can be installed on the first bracket 100A. The water outlet pipe and the water inlet pipe respectively pass through the lower rod assembly 10A and are connected to the connector of the hinge device 20 to form a water channel connecting the connecting rod assembly 10 and the hinge device 20. Figure 3 、 Figure 4 As shown, a water pump 101 may also be provided on the first bracket 100A. The water pump is provided on the first bracket, and the water outlet and water inlet of the water pump are both arranged toward the hinge device. The water outlet pipe and water inlet pipe connecting the water outlet, water inlet, and hinge device can be conveniently passed through the connecting rod assembly and connected to the connector of the hinge device, respectively. This minimizes the length of the water pipes within the connecting rod assembly and makes the connection more convenient. At the same time, a single docking of the connecting rod assembly and the hinge device can achieve rapid docking of the water channels connecting the connecting rod assembly and the hinge device.

[0069] Further, such as Figure 3 、 Figure 4 As shown, the first bracket 100A is further provided with a flow sensor 103, which is disposed between the water pump 101 and the hinge device 20. The flow sensor 103 is connected to the water outlet 101a and the water outlet pipe, and is also electrically connected to the control board 110. The flow sensor 103 transmits real-time flow data from the water outlet 101a of the water pump 101 to the control board 110. The control board 110 can adjust the control strategy of the water pump 101 in real time based on the received flow data. The flow sensor 103 can measure the real-time flow data of the water pump 101 and transmit it to the control panel 110 in real time. The control panel 110 can comprehensively determine the operating status of the water pump 101 based on the real-time flow data transmitted by the flow sensor 103 and the operating instructions output by the control panel 110 to the water pump 101. If the water pump 101 fails while the floor scrubber is operating, the control panel 110 will immediately output the fault condition to the display module and voice module of the handle 50, allowing the handle 50 to promptly inform the user of the current fault condition of the floor scrubber through "sound, light, and screen display". After the flow sensor is installed in the connecting rod assembly, the control panel can adjust the control strategy of the water pump in real time based on the water pump flow data, so that the floor scrubber can operate more energy-efficiently and efficiently.

[0070] Thus, using the control board and the first bracket to secure the battery pack together allows for more reliable fixation, ensuring stable power supply to the control board and thus ensuring the stable operation of the scrubber's control system. Securing the water pump and flow sensor to the first bracket also shortens the distance between the water pump and flow sensor and the control board, making the electrical connection between the water pump, flow sensor, and the control board more reliable, thereby improving the stability of the scrubber's operation and making it easier to inspect and maintain the scrubber in the event of a malfunction.

[0071] Specifically, such as Figure 3 、 Figure 4 、 Figure 7 As shown, the first bracket 100A is arranged in the lower rod assembly 10A; the first bracket 100A will not slide or fall off in the lower rod assembly 10A; the first bracket 100A arranged inside the lower rod assembly 10A serves as a bearing and connection unit for the internal components of the lower rod assembly 10A, so as to realize the integrated installation of the waterway, circuit and power supply in the lower rod assembly 10A; the first bracket 100A placed inside the lower rod assembly 10A supports the inner wall of the lower rod assembly 10A, and can also increase the structural strength and rigidity of the lower rod assembly 10A.

[0072] It should be noted that this does not limit whether the first bracket 100A is installed inside the lower rod assembly 10A or the upper rod assembly 10B. Of course, the first bracket 100A can also be installed between the lower rod assembly 10A and the upper rod assembly 10B. As long as the technical solution of the first bracket 100A being installed inside the connecting rod assembly is within the scope of protection of this application. It should also be noted that the specific number of first brackets 100A is not limited here. The first bracket 100A can be set to at least one, and at least one first bracket 100A can be set in at least one of the lower rod assembly 10A or the upper rod assembly 10B. The technical solution of at least one first bracket 100A being installed inside the connecting rod assembly is within the scope of protection of this application.

[0073] In this way, the first bracket is adapted to the hollow shape of the lower rod assembly or the upper rod assembly, so that when the floor scrubber is working, the first bracket placed inside the lower rod assembly or the upper rod assembly will not slide or fall off; the first bracket arranged inside the lower rod assembly or the upper rod assembly serves as a load-bearing and connection unit for the internal components of the connecting rod assembly to realize the integrated installation of the water circuit and the circuit in the connecting rod assembly; on the other hand, since the lower rod assembly and the upper rod assembly are hollow inside, the first bracket placed inside the lower rod assembly and / or the upper rod assembly supports the inner wall of the lower rod assembly and the upper rod assembly, and can also increase the structural strength and rigidity of the lower rod assembly and / or the upper rod assembly, thereby further increasing the rigidity of the connecting rod assembly while reducing the overall weight of the connecting rod assembly.

[0074] In one or more optional embodiments, as Figure 3 、 Figure 4 As shown, the first bracket 100A, which houses the battery pack 120, control panel 110, water pump 101, and flow sensor 103, is mounted within the lower connecting rod assembly 10A, closer to the tractor head 30. This allows the control panel 110 mounted on the first bracket 100A to be electrically connected to the drive motor, water electrolysis module (not shown), and lighting within the tractor head via the hinge assembly 20 over the shortest distance. In particular, since the "water-dust circulation" floor scrubber operates due to the "water squeezer" within the tractor head squeezing the surface of the cleaning roller, which generates a high operating current in the drive motor that drives the cleaning roller, the shorter the distance between the drive motor and the control panel 110 and the battery pack 120, the less electrical loss (ultimately dissipated as heat) in the wiring harness connecting the drive motor and the control panel. This also reduces the radio electromagnetic interference emitted by the wiring harness connecting the drive motor and the control panel, thereby reducing the energy consumption of the floor scrubber, extending the battery life of the floor scrubber, and minimizing electromagnetic radiation emitted by the floor scrubber.

[0075] In one or some optional embodiments, the first bracket 100A on which the battery pack 120, the control panel 110, the water pump 101, and the flow sensor 103 are installed is installed in the area jointly surrounded by the lower rod housing 100a and the upper rod housing 100b, that is, between the lower connecting rod assembly 10A and the upper connecting rod assembly 10B, so that the control panel 110 installed in the first bracket 100A can be electrically connected to the drive motor, the water electrolysis module (not shown in the drawings), and the lighting lamp in the tractor through the hinge device 20 at an appropriate distance. Although the power loss generated in the cable harness connecting the drive motor and the control board is moderate, and the radio electromagnetic wave interference sent outward by the cable harness connecting the drive motor and the control board is also moderate, in return the control board is relatively far away from the tractor head. The control board, water pump, battery, and flow sensor are not easily damaged by the water that gradually enters and penetrates the electronic components during the high-water flushing mode of the floor scrubber because the entire floor scrubber head is placed under the faucet for flushing. At the same time, the control board is closer to the handle, so when the control board, water pump, battery, flow sensor and other components are damaged, it is easier to further replace the damaged components after disassembling the connecting rod assembly as a whole.

[0076] In one or some optional embodiments, the first bracket 100A on which the battery pack 120, the control panel 110, the water pump 101, and the flow sensor 103 are installed is installed in the upper connecting rod assembly 10B closer to the handle 50. In this way, the control panel 110 installed in the first bracket 100A can be electrically connected to the drive motor, the water electrolysis module (not shown in the drawings), and the lighting in the tractor through the hinge device 20 over a longer distance. Although the power loss generated in the cable harness connecting the drive motor and the control board is large, and the radio electromagnetic wave interference sent outward by the cable harness connecting the drive motor and the control board is also large, in return the control board is very far away from the tractor head. The control board, water pump, battery, and flow sensor are less likely to be damaged by the water that gradually enters and seeps into the electronic components during the high-water flushing mode of the floor scrubber because the entire floor scrubber head is placed under the faucet for flushing. At the same time, the control board is closer to the handle, so when the control board, water pump, battery, flow sensor and other components are damaged, it is easier to further replace the damaged components after disassembling the connecting rod assembly as a whole, or simply replace the connecting rod assembly and handle together.

[0077] In one or more optional embodiments, as Figures 6 to 8 As shown, the connecting rod assembly further includes a second bracket 100B, one end of the second bracket 100B is provided with a second lower port (not marked in the drawings), and the other end is provided with a second upper port (not marked in the drawings), the second lower port faces the connecting head of the hinge device 20, and the second upper port faces the lower port of the first bracket 100A. The water pump (not marked in the drawings) can be installed on the second bracket 100B. Of course, Figure 6 、 Figure 8 As shown, the second bracket 100B can also be mounted with a control board 110 and a battery pack 120 .

[0078] In this way, the second bracket and the control board jointly fix the battery pack to improve the integration of the second bracket. After the second bracket with the battery pack and the control board installed is installed in the upper rod shell, the rigidity of the upper rod assembly is also improved; the battery pack is placed in the connecting rod assembly as a power source, and the control board is placed in the connecting rod assembly as the core center of the control system of the floor scrubber. By setting the second bracket, the connecting rod assembly is convenient for disassembly and installation, and it is also convenient for replacement and maintenance of the battery pack and control board.

[0079] It should be noted that the second bracket 100B can of course also be installed into the lower rod housing 100a and become a part of the lower rod assembly 10A. It is not limited here whether the second bracket 100B is installed inside the lower rod assembly 10A or the upper rod assembly 10B. Of course, the second bracket 100B can also be installed between the lower rod assembly 10A and the upper rod assembly 10B. As long as the second bracket 100B is installed inside the connecting rod assembly 10, the technical solution is within the protection scope of this application. It should also be noted that the specific number of second brackets 100B is not limited here. The second bracket 100B can be set to at least one, and at least one first bracket 100A can be provided in at least one of the lower rod assembly 10A or the upper rod assembly 10B. The technical solution of at least one first bracket 100A being installed inside the connecting rod assembly is within the protection scope of this application. It should also be noted that, when the first bracket 100A and the second bracket 100B are simultaneously installed in the lower rod assembly 10A or the upper rod assembly 10B, it is not limited here as to which of the first bracket 100A and the second bracket 100B is closer to the hinge device 20 or the handle 50. It can be flexibly configured according to actual needs. As long as the devices installed on the first bracket 100A and the second bracket 100B can achieve reliable electrical connection, the technical solutions in which the first bracket 100A and the second bracket 100B are installed inside the connecting rod assembly 10 are within the protection scope of this application.

[0080] Furthermore, the battery pack 120 includes two or more batteries connected in series and then in parallel. The control board 110 is electrically connected to the water pump 101 and the drive motor in the tractor head 30 that drives the cleaning roller. The control board 110 is also electrically connected to the charging port of the handle 50. When the control board 110 controls the operation of the water pump 101 and the drive motor, the battery pack 120 is in an external discharge state. When an external power adapter is electrically connected to the charging port, the external power adapter charges the battery pack 120 through the control board 110.

[0081] In this way, a battery pack and a control board are set on the second bracket. In the connecting rod assembly, the control board is electrically connected to the water pump and the drive motor that drives the cleaning roller in the tractor to rotate. The control board is provided with an electrode sheet group for clamping the battery pack, which can conveniently connect and fix the hinge device, the connecting rod assembly and the handle to each other, and integrate the power supply, circuit and control board into the interior of the connecting rod assembly, reducing the overall volume of the equipment and improving the protection and convenience of installation and disassembly; at the same time, a single docking of the connecting rod assembly with the hinge device can realize the rapid docking of the circuit line connected to the hinge device, and a single docking of the connecting rod assembly with the handle can realize the rapid docking of the circuit line connected to the connecting rod assembly and the handle.

[0082] Similar to the other aforementioned embodiments, the second bracket 100B on which the water pump 101 or the control panel 110 or the battery pack 120 or the flow sensor 103 is installed can be installed in any one of the lower rod housing 100a and the upper rod housing 100b, or can be installed between the lower rod housing 100a and the upper rod housing 100b; that is, the second bracket 100B on which the water pump 101 or the control panel 110 or the battery pack 120 or the flow sensor 103 is installed can be installed in the lower rod assembly 10A or the upper rod assembly 10B or between the lower rod assembly 10A and the upper rod assembly 10B. At this time, the water pump 101, the control board 110, the battery pack 120, and the flow sensor 103 are respectively installed on the first bracket 100A or the second bracket 100B according to actual needs. The first bracket 100A and the second bracket 100B are also electrically connected through a third terminal wiring harness (not marked in the drawings). One of the first bracket 100A and the second bracket 100B is electrically connected to the connector of the hinge device 20 through the first terminal wiring harness 105 and is electrically connected to the tractor 30 through the hinge device 20. The other one of the first bracket 100A and the second bracket 100B is electrically connected to the handle 50 through the first terminal wiring harness 105. The specific technical solution is similar to that of the other aforementioned embodiments and will not be repeated here.

[0083] In one or more optional embodiments, the handle 50 includes a voice module (not shown in the figures), a Bluetooth module (not shown in the figures), and a display module (not shown in the figures) electrically connected to the control panel 110. The handle 50 also includes a charging port (not shown in the figures) electrically connected to the control panel 110. The handle 50 also includes a button (not shown in the figures) electrically connected to the control panel 110. These buttons can be used to turn the scrubber on and off, switch operating modes, or enable or disable voice commands. The display module displays the current operating mode and status of the scrubber, while the voice module provides voice prompts when various functions are triggered. The Bluetooth module enables communication between the scrubber and other smart terminals, allowing users to access additional operating status and historical data through other smart terminals, which is not available on the display module. Furthermore, the scrubber can be remotely configured through other smart terminals, for example, to schedule automatic self-cleaning.

[0084] In one or some optional embodiments, the control board 110 is further provided with at least one temperature sensor (not shown in the drawings), which senses the temperature of the control board 110 and the battery pack 20 and feeds back the temperature to the display module on the handle 50 through a signal connection.

[0085] In this way, the control panel is also provided with at least one temperature sensor, which allows the control panel to obtain the temperature of the battery pack and the control panel in real time. The control panel can then use the temperature data measured in real time to promptly adjust the control strategy of the water pump and the drive motor, so that the floor scrubber can work more energy-efficiently and efficiently.

[0086] In one or more optional embodiments, as Figures 1 to 8 As shown, the connecting rod assembly 10 also includes an adjusting mechanism 10C. The lower end of the upper rod housing 100b is sleeved on the outside or inside of the upper end of the lower rod housing 100a. The upper rod housing 100b can slide relative to the lower rod housing 100a to adjust the total length of the connecting rod assembly 10. The adjusting mechanism 10C can allow the upper rod housing 100b and the lower rod housing 100a to be in a relatively sliding state or a locked state, and allow the connecting rod assembly 10 to become a whole that does not need to be disassembled.

[0087] Furthermore, a first rack structure (not shown in the drawings) is provided on the outer surface / inner surface of one of the upper rod housing 100b and the lower rod housing 100a, and a corresponding second rack structure (not shown in the drawings) is provided on the inner surface / outer surface of the other of the upper rod housing 100b and the lower rod housing 100a. When the adjustment mechanism 10C is set in a slidable state, the first rack structure and the second rack structure are disengaged, and the upper rod housing 100b and the lower rod housing 100a are in a state in which they can slide relative to each other; when the adjustment mechanism 10C is set in a locked state, the first rack structure and the second rack structure are coupled to each other, and further similar to the locking effect of the adjustment mechanism 10C, the upper rod housing 100b and the lower rod housing 100a are in a locked state in which they cannot slide relative to each other.

[0088] In this way, the adjustable-length connecting rod assembly can accommodate the different grip height requirements of users of different heights in the household. The user simply presses the adjustment mechanism to slide the upper rod housing relative to the lower rod housing to easily adjust the overall length of the connecting rod assembly, improving the adaptability of the floor scrubber to home users. Of course, the overall length of the connecting rod assembly can also be adjusted to a minimum during transportation and storage of the entire floor scrubber and connecting rod assembly, thereby reducing the space required for transportation or storage. If the floor scrubber malfunctions, if the voice module on the handle can still accurately announce the fault point, the user only needs to remove the entire connecting rod assembly from the floor scrubber and return it to the manufacturer for replacement. The manufacturer will then perform a detailed inspection at the factory and use the repaired connecting rod assembly as a spare part for subsequent maintenance. The manufacturer's customer service also eliminates the time-consuming and labor-intensive task of remotely locating the fault point for the user, allowing the customer to directly replace the entire connecting rod assembly. Even if the voice module on the handle of a faulty floor scrubber fails to accurately announce the fault point, the user can still replace the entire connecting rod assembly 10, significantly reducing the time the user spends waiting for spare parts and improving customer satisfaction.

[0089] In one or more optional embodiments, as Figure 4 As shown, the first terminal harness 105 can automatically adjust its length as the upper rod housing 100b slides relative to the lower rod housing 100a. The operation of the floor scrubber is not affected during the process of adjusting the length of the connecting rod assembly. The middle section of the first terminal harness 105 is a spring-shaped spiral coil. Since the middle section of the first terminal harness has been prefabricated into a spring-shaped spiral coil, when the total length of the connecting rod assembly is stretched to its maximum, a small portion of the middle section of the first terminal harness can still be kept in the spring-shaped spiral coil. When the total length of the connecting rod assembly is stretched to its shortest, the middle section of the first terminal harness has the largest number of spring-shaped spiral coils. Of course, the inner walls of the upper rod housing and the lower rod housing can also be covered with sound-absorbing foam to prevent the first terminal harness from hitting the inner walls of the upper rod housing and the lower rod housing and producing noise when the floor scrubber is pulled. At the same time, the adjustable length of the first terminal harness also greatly facilitates the assembly of the connecting rod assembly and the user's own inspection and maintenance. Since the length of the first terminal harness can be easily adjusted, during assembly or maintenance, the operator can easily install / remove the aforementioned first bracket and second bracket from either end of the connecting rod assembly. The operator can first electrically connect the first bracket and the second bracket and then install them into the connecting rod assembly in sequence, or the operator can first install the two into the connecting rod assembly and then electrically connect them.

[0090] When the connecting rod assembly 10 of a normally working floor scrubber is separated from the hinge device 20, the drag head 30 does not work, but the connecting rod assembly 10 and the handle 50 continue to work, and the battery pack 120 can still be charged through the charging port. The voice module can broadcast the current status, and the Bluetooth module can communicate with other smart terminals. Furthermore, since the control board 110 and the battery pack 120 are installed in the connecting rod assembly 10, the connecting rod assembly 10 connected to the handle 50 can naturally continue to work. When the floor scrubber fails, after eliminating the failure of the drag head and the handle, the self-test mode of the floor scrubber can be activated through the button on the handle, and the water pump and flow sensor installed in the lower rod assembly can be further checked for failure. If the failure of the water pump and flow sensor is further eliminated, the user only needs to return the upper rod assembly connected to the handle without disassembling it, and can directly return it to the factory for replacement to obtain a usable floor scrubber as quickly as possible. Alternatively, when the user purchases a floor scrubber, they purchase a configuration that includes another set of connecting rod assemblies. When a fault occurs, the user can simply replace the faulty set of connecting rod assemblies by exchange and use the floor scrubber immediately without delaying the user's daily cleaning. The faulty components can be returned to the factory for repair, thereby improving customer satisfaction.

[0091] Because the lower and upper rod assemblies already house most of the scrubber's control components (including the control panel, water pump, flow sensor, and battery pack), users can easily replace the connecting rod assembly if they encounter any scrubber malfunctions, once the tractor and handle have been properly repaired. This instantly solves their daily cleaning needs. The replaced connecting rod assembly can then be returned to the manufacturer for repair, minimizing disruption to daily use and improving customer satisfaction.

[0092] In one or more optional embodiments, as Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 As shown, the lower rod assembly 10A also includes a first connecting kit, which is detachably connected to the lower open end of the lower rod housing 100a. The first connecting kit includes a lower rod lower docking sleeve 100C: the lower rod lower docking sleeve 100C is connected to the lower open end and can be quickly docked with the connecting head of the hinge device 20.

[0093] Further, such as Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 As shown, the upper end opening of the lower rod lower docking sleeve 100C is also provided with a lower rod lower terminal seat 100C1. The control board 110 is electrically connected to the first terminal harness 105, and the end of the first terminal harness 105 is provided with a lower docking terminal 105c. The lower docking terminal 105c passes through the lower port and the lower rod lower docking sleeve 100C in sequence, and after passing through the lower rod assembly 10A, it is electrically connected to the connector of the hinge device 20 through the lower rod lower terminal seat 100C1.

[0094] Specifically, if Figure 3 、 Figure 4 、 Figure 6 、 Figure 7As shown, the upper open end of the lower rod housing 100a is connected to a regulating mechanism 10C, and the lower open end of the lower rod housing 100a is connected to a lower rod docking sleeve 100C, and a first bracket 100A or a second bracket 100B is installed in the lower rod housing 100a between the lower rod docking sleeve 100C and the regulating mechanism 10C, and both ends of the first bracket 100A or the second bracket 100B are open, and one end of the first bracket 100A or the second bracket 100B is provided with a lower port, and the lower port is connected to the lower rod docking sleeve 100C; the other end of the first bracket 100A or the second bracket 100B is provided with an upper port, and the upper port is connected to the handle 50 wire. Furthermore, an opening is provided on one side of the lower rod docking sleeve 100C, and a lower rod terminal seat 100C1 is provided on the other side; the lower rod docking sleeve 100C is sleeved on the connecting head of the hinge device 20 through the opening, and is adapted to be connected to the lower port of the first bracket 100A through the lower rod terminal seat 100C1, and the lower rod terminal seat 100C1 is electrically connected to the terminal seat in the connecting head (not marked in the drawing) to connect and fix the first bracket 100A or the second bracket 100B and the hinge device 20.

[0095] In one or some optional embodiments, the hinge device 20 includes a connecting head and a hinge head, and the end of the connecting head of the hinge device 20 is provided with a connecting terminal (not marked in the drawings), and the connecting terminal is provided with a connecting terminal and a water inlet interface and a water outlet interface (not marked in the drawings). The lower rod lower docking sleeve 100C is sleeved on the connecting head of the hinge device 20, and the connecting end of the connecting head extends into the lower rod lower terminal seat 100C1 of the lower rod lower docking sleeve 100C, and the lower rod lower terminal seat 100C1 is adapted and fixed to the lower port of the first bracket 100A.

[0096] In this way, the connecting rod assembly and the hinge device are detachably connected to each other through the lower rod lower docking sleeve, making the connection between the hinge device and the connecting rod assembly more stable and improving the stability of the structure. At the same time, through a single quick docking of the connecting rod assembly and the hinge device, the mechanical connection, electrical connection, and water connection of the connecting rod assembly and the hinge device can be completed, which is efficient and convenient.

[0097] In one or some optional embodiments, the connecting rod is also hinged to a tractor head 30 at the hinge head of the hinge device 20, and the water pump 101 in the connecting rod assembly 10 is controlled by the handle 50 to supply water to the tractor head 30, and the battery pack 120 in the connecting rod assembly 10 is controlled by the handle 50 to supply power to the water pump 101 and the drive motor, thereby performing cleaning work.

[0098] In the present application, the mechanical docking of the connecting rod assembly and the hinge assembly simultaneously connects the electrical circuit and waterway between the two devices. This is different from the mechanical docking of the connecting rod assembly and the handle, which only connects the electrical circuit between the connecting rod assembly and the handle. Furthermore, the docking interfaces at the two mechanical docking locations are designed with foolproofing features, preventing users from incorrectly docking the hinge assembly, connecting rod assembly, and handle. This prevents incorrect installation of the components and improves device installation efficiency. Furthermore, if an electrical connection failure occurs, if the control board reports a water pump or drive motor connection failure, the fault is likely only due to a faulty electrical connection between the connecting rod assembly and the hinge assembly. If the handle's display device displays a fault, the fault is likely only due to a faulty electrical connection between the connecting rod assembly and the handle. If the control board reports a low water pump flow rate, in addition to the possibility of a water pump failure, a leak in the waterway connection between the connecting rod assembly and the hinge assembly is also possible.

[0099] In the present application, since the first bracket and / or second bracket are mounted in the cavities of the lower rod housing and the upper rod housing, and a water pump, flow sensor, battery pack, and control panel are mounted on the first bracket or the second bracket, and the cavities of the upper rod assembly and the lower rod assembly are free of any components other than the first terminal harness, the second terminal harness, or the third terminal harness, the weight of the lower rod assembly and the upper rod assembly together remains very light. The center of gravity of the connecting rod assembly also makes it easier for the user to push and pull the connecting rod by holding the handle. In this embodiment, only the mechanical docking of the lower rod assembly and the hinge device simultaneously achieves the simultaneous docking of the circuit lines and water channels between the two, while the mechanical docking of the upper rod assembly and the handle only achieves the simultaneous docking of the corresponding circuit lines between the two. Furthermore, due to the differences in the corresponding docking interfaces at the two mechanical docking locations, each docking interface has been fool-proofed, so the user will not mistakenly dock the hinge device, the connecting rod assembly, and the handle, thereby avoiding the problem of incorrect installation of the various components and improving the installation efficiency of the device. On the other hand, the control panel is installed in the connecting rod assembly, which is located close to the handle held by the user. In addition, if the floor scrubber fails, it is very likely that the control panel is at fault. In this case, the connecting rod assembly and the handle are returned to the factory for replacement. This is much easier than the tedious process of removing one or two sections of the upper and lower rod assemblies and repeatedly verifying where the problem occurred and repeatedly comparing the fault points in the prior art. Of course, users who have purchased floor scrubbers equipped with multiple connecting rod assemblies can directly take out the corresponding spare parts and replace them by themselves, and then return the faulty spare parts as a whole to the factory. This will not affect the user's demand for the frequency of use of the floor scrubber for daily cleaning, thereby improving the user experience.

[0100] Second, as Figures 1 to 8 As shown, the present invention provides a floor scrubber, which includes a tractor head 30 and the connecting rod assembly 10 described in the first aspect. The present invention connects and fixes the hinge device 20, the connecting rod assembly 10 and the handle 50 to each other, and integrates the power supply, circuit, water channel and control panel into the interior of the connecting rod assembly 10, thereby reducing the overall volume of the equipment and improving the protection and convenience of installation and disassembly; at the same time, the connecting channel between the connecting rod assembly 10 and the hinge device 20 accommodates the circuit line and the water channel connecting the water pump 101 and the hinge device 20; and different from the connection between the connecting rod assembly and the hinge device, the connecting channel between the connecting rod assembly 10 and the handle 50 only accommodates the circuit channel connecting the water pump 101 and the handle 50. During installation, the user can correctly adapt and install the hinge device 20, the connecting rod assembly 10 and the handle 50 by distinguishing whether the connecting rod assembly 10 is connected to the water channel and circuit of the hinge device 20 at one end, or only to the circuit of the handle 50 at one end, thereby avoiding the problem of incorrect installation between the components and improving the installation efficiency of the equipment.

[0101] like Figures 1 to 8 As shown, the present invention provides a hinge device 20 for a floor scrubber, which is used to connect the drag head 30 and the connecting rod assembly 10 of the floor scrubber. The connecting rod assembly 10 is provided with a water pump 101, a battery 120, and a control board 110. The drag head 30 is provided with a motor and a water tank for driving the cleaning roller to rotate. The water pump 101 transports clean water in the water tank to the surface of the cleaning roller and recovers the sewage on the surface of the cleaning roller to the water tank. The hinge device 20 includes a rotating hinge and a connector, which is hinged to the drag head 30; the connector is detachably connected to the connecting rod assembly 10, and the connector includes an exposed portion (not marked in the drawings), which fixedly connects the connector and the rotating hinge at an angle; the drag head 30, the connecting rod assembly 10, the connector and the rotating hinge accommodate pipes connecting the water pump and the water tank and wires electrically connected to the battery, the water pump, the control board and the motor.

[0102] In this way, the hinge device of the present invention for the floor scrubber includes a rotating hinge body and a connector, and the rotating hinge body is hinged to the drag head of the floor scrubber; the connector is detachably connected to the connecting rod assembly of the floor scrubber, and the connector includes an exposed portion, and the exposed portion fixedly connects the connector and the rotating hinge body at an angle; the drag head, connecting rod assembly, connector and rotating hinge body of the floor scrubber accommodate water pipes connecting the water pump and the water tank and electrical wires electrically connected to the battery, water pump and motor, and the water pipes and electrical wires built into the hinge device can be docked with the drag head and connecting rod assembly in a single mechanical docking, which is convenient for maintenance and replacement of the hinge device of the floor scrubber without causing damage to the water circuit and the circuit, thereby improving the efficiency of maintenance and replacement of the hinge device. Compared to the prior art, the present invention connects the connecting rod assembly of the floor scrubber to the mop head by providing a hinge device. This not only reduces the volume of the hinge device within the overall floor scrubber, but also houses the pipes and water pump for water circulation, as well as circuits connected to the water pump, power supply, and control system, within the connector and the rotating hinge body. This achieves water and circuit connections, facilitating maintenance and replacement of the hinge device without damaging the internal water and circuit connections, thereby improving the maintenance and replacement efficiency of the hinge device. Furthermore, the connecting rod assembly includes a lower rod assembly and an upper rod assembly with adjustable overall length to address the problem of varying height requirements for the floor scrubber's connecting rod assembly due to different users in a household. The connection channel between the connecting rod assembly and the hinge device contains the circuit line and the water channel connecting the water pump and the hinge device; and unlike the connection between the connecting rod assembly and the hinge device, the connection channel between the connecting rod assembly and the handle only contains the circuit channel connecting the water pump, the control panel and the handle. During installation, the user can correctly match the hinge device, the connecting rod assembly and the handle by distinguishing whether the connecting rod assembly is connected to the water and circuit dual-circuit of the hinge device, or the end of the connecting rod assembly is only connected to the circuit of the handle, thereby avoiding the problem of incorrect installation between the various components and improving the installation efficiency of the equipment. On the other hand, the present application can also solve the problem of the upper rod assembly and the lower rod assembly needing to be disassembled with great difficulty when the floor scrubber malfunctions, and the problem of repeatedly returning the two components to the factory for repair and replacement is time-consuming and costly. A floor scrubber equipped with the connecting rod assembly of the present application can broadcast the specific fault point through the voice module on the handle, and then accurately remove the connecting rod assembly to replace and maintain the entire faulty connecting rod assembly as a whole, reducing the number of times the user disassembles and assembles the connecting rod assembly and the number of times spare parts are repeatedly transported back and forth, thereby improving the user experience. The connecting rod assembly solves the problem of inconvenient disassembly and maintenance of the connecting rod of the floor scrubber in the prior art.

[0103] In one or some optional embodiments, the connecting body of the hinge device 20 includes an exposed portion and an internal connection portion (not shown in the drawings). When the floor scrubber completes the connection between the connecting rod assembly 10, the hinge device 20 and the drag head 30, the surface of the exposed portion is exposed and is located between the connecting rod assembly 10 and the rotating hinge body; the entire outer cylindrical wall of the internal connection portion is transitionally matched with the inner wall of the connecting rod assembly 10, and the cylindrical depth of the entire transition match is approximately twice the diameter of the inner wall of the connecting rod assembly 10. In this way, the hinge device 20 and the connecting rod assembly 10 can maintain stable and consistent cooperation in the axial direction, thereby ensuring the concentricity and stability of the cooperation between the two.

[0104] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or perform equivalent replacements or combinations on some structures (technical features) in one or more embodiments, and these modifications or replacements or combinations do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention, unless the embodiments explicitly exclude the possibility of replacing or combining structures (technical features) in different embodiments, or such replacement or combination is contrary to the overall concept of the invention.
