Description

Technical Field

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

[0002] In the early days, people used brooms, mops, floor wipes, etc. to clean the floor. These tools mainly rely on manual operation to complete the cleaning work. With the advancement of science and technology, people's requirements for floor cleaning tools have gradually increased. The first to appear was the vacuum cleaner, which relies on electricity to generate negative pressure to absorb garbage, dust, etc. on the ground. According to the cleaning methods and the circulation channels of small and large particles of garbage, this type of technology is usually classified as air-dust circulation technology. However, due to the limitations of its working principle, the vacuum cleaner cannot clean some garbage and stains that are firmly attached to the ground. Therefore, a new "water-dust circulation" floor scrubber has appeared. The motor drives the cleaning cylinder to wipe the ground. At the same time, the floor cleaner will also be equipped with a water supply system and a sink to clean the cleaning cylinder, thereby perfectly cleaning the ground.

[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, wherein 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, and the upper and lower side walls of the rod body are provided with limiting grooves, and 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, and 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, wherein the connecting rod comprises a hinge assembly, a connecting rod assembly, a handle assembly and a connecting assembly, wherein the connecting rod assembly comprises a first connecting rod assembly and a second connecting rod assembly, wherein a water pump is arranged in the first connecting rod assembly; wherein the connecting assembly comprises a first connecting assembly and a second connecting assembly; wherein the first connecting assembly is used to connect one end of the first connecting rod assembly with the hinge assembly, wherein the first connecting assembly contains a circuit connecting the water pump and the hinge assembly and a circulating water circuit; wherein the second connecting assembly is used to connect the other end of the first connecting rod assembly with one end of the second connecting rod assembly; wherein the other end of the second connecting rod assembly is connected with a handle assembly, wherein the second connecting assembly contains a circuit channel connecting the water pump and the handle assembly; wherein the present invention solves the problem of external damage to the circuit elements, water circuit and circuit of the connecting rod when the floor scrubber takes out and puts in the water tank or performs maintenance on the body, while reducing the volume.

[0005] In the embodiments of the applicant's patent series, the battery pack and the control panel are both arranged in the first connecting rod assembly connected between the second connecting rod assembly and the hinge assembly. In order to ensure the reliable connection between the hinge assembly, the first connecting rod assembly and the second connecting rod assembly in daily use, the two clamping parts are clamped very tightly, which is not easy to disassemble. When the user fails to use the floor scrubber after a period of use, most of the fault points are in the battery or control panel in the first connecting rod assembly. At this time, it is necessary to disassemble the first connecting rod assembly in the middle of the lower clamp. This disassembly process brings great inconvenience to the user in terms of maintenance and often leads to customer complaints. In the prior art, even if there is a floor scrubber with a connecting rod assembly that can be combined and replaced, it is still impossible to solve the problem of different height requirements for the length of the floor scrubber connecting rod assembly due to different users in a family.

[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, thereby improving the convenience of disassembling faulty components.

[0080] Specifically, Figure 3 , Figure 4 , Figures 8 to 10 As shown, the first bracket 100A is detachably mounted in the lower rod assembly (10A, 10') and is used in the connecting rod assembly 10 of the floor scrubber. The connecting rod assembly 10 includes at least one lower rod assembly (10A, 10'). The lower rod assembly (10A, 10') includes a lower rod housing (100a, 100) with the first bracket 100A built in. The connecting rod assembly 10 connects the tractor head 30 and the handle 50 of the floor scrubber. The top of the first bracket 100A is open and The bottom is closed and semi-closed in a cylindrical and semi-box shape. The two ends of the first bracket 100A are respectively provided with a lower port and an upper port. The first bracket 100A is installed with a water pump 101. The control board 110 in the upper rod assembly (10B, 40) is electrically connected to the water pump 101 and controls the operation of the water pump 101. The connection between the connecting rod assembly 10 and the hinge device 20 and the handle 50 is released, and the first bracket 100A is taken out from either end of the lower rod housing (100a, 100), and the water pump 101 can be operated.

[0081] Specifically, Figure 3 , Figure 4 , Figures 8 to 10As shown, a water pump 101 is detachably mounted on the first bracket 100A and is arranged on one side of the first bracket 100A close to the lower port. The water pump 101 is provided with a water outlet 101a and a water inlet 101b, and the water outlet 101a and the water inlet 101b are respectively connected to a water outlet pipe and a water inlet pipe (not shown in the drawing).

[0082] Furthermore, the water outlet 101a and the water inlet 101b are both arranged in the direction of the hinge device 20, and the water outlet 101a and the water inlet 101b are respectively provided with a water outlet pipe and a water inlet pipe, which respectively pass through the connecting rod assembly 10 and are connected to the connecting head of the hinge device 20 to form a water channel connecting the connecting rod assembly 10 and the hinge device 20.

[0083] In this way, a water pump is arranged on the first bracket, and the water outlet and water inlet of the water pump are arranged toward the direction of the hinge device, so that 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 respectively and connected with the connecting head of the hinge device, so that the length of the water pipeline inside the connecting rod assembly can be minimized and the connection can be more convenient. At the same time, a single docking of the connecting rod assembly and the hinge device can realize the rapid docking of the water channel connecting the connecting rod assembly and the hinge device.

[0084] In one or some alternative embodiments, Figures 1 to 12 As shown, the lower rod assembly (10A, 10') and the upper rod assembly (10B, 40) are hollow inside, and the connecting rod assembly 10 also includes a first bracket 100A, which is open at both ends and is arranged in the lower rod assembly (10A, 10') or the upper rod assembly (10B, 40); a lower port is provided at one end of the first bracket 100A, and the lower port faces the connecting head of the hinge device 20; an upper port is provided at the other end of the first bracket 100A, and the upper port is connected to the handle 50 by a wire.

[0085] Specifically, Figure 3 , Figure 4 , Figures 8 to 10 As shown, the first bracket 100A is arranged in the lower rod assembly (10A, 10'); the first bracket 100A will not slide or fall off in the lower rod assembly (10A, 10'); the first bracket 100A arranged inside the lower rod assembly (10A, 10') serves as a bearing and connection unit for the internal components of the lower rod assembly (10A, 10') to achieve the integrated installation of the waterway, circuit and power supply in the lower rod assembly (10A, 10'); the first bracket 100A placed inside the lower rod assembly (10A, 10') supports the inner wall of the lower rod assembly (10A, 10'), and can also increase the structural strength and rigidity of the lower rod assembly (10A, 10').

[0086] It should be noted that it is not limited here whether the first bracket 100A is installed inside the lower rod assembly (10A, 10') or the upper rod assembly (10B, 40). Of course, the first bracket 100A can also be installed between the lower rod assembly (10A, 10') and the upper rod assembly (10B, 40). As long as the technical solution of the first bracket 100A being installed inside the connecting rod assembly is within the protection scope of this application. It should also be noted that the specific number of the first bracket 100A is not limited here. The first bracket 100A can be set to at least one, and at least one of the first brackets 100A can be set in at least one of the lower rod assembly (10A, 10') or the upper rod assembly (10B, 40). 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.

[0087] In this way, the first bracket is adapted to the hollow shape inside 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 bearing and connecting unit for components inside the connecting rod assembly, so as to realize the integrated installation of waterways and circuits 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 walls 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.

[0088] In one or some alternative embodiments, Figure 4 , Fig. 9 , Fig.10 As shown, the lower rod housing (100a, 100) is hollow to form a cavity, having an upper open end and a lower open end; the first bracket 100A can be installed into the lower rod housing (100a, 100) from any end, and during maintenance, the first bracket 100A can be taken out from any end of the lower rod housing (100a, 100).

[0089] In one or some alternative embodiments, Figure 4 , Fig. 9 , Fig.10 As shown, the upper rod housing (100b, 400) is hollow to form a cavity, having a second upper opening end (not marked in the drawings) and a second lower opening end (not marked in the drawings), and the second upper opening is connected to the handle 50; the second bracket 400A can be installed into the upper rod housing (100b, 400) from either end, and during maintenance, the second bracket 400A can be taken out from either end of the upper rod housing.

[0090] In one or some alternative embodiments, Figures 3 to 5 , Figures 8 to 12 As shown, the second bracket 400A is provided with a battery pack 120 and a control board 110, and the battery pack 120 is provided on the side of the second bracket 400A close to the lower port; the control board 110 is threadedly connected to the fixing nut column (not marked in the figure) of the second bracket 400A, and the control board 110 is provided with an electrode sheet group (not marked in the figure), and the electrode sheet group clamps the battery pack 120. In this way, the second bracket and the control board jointly fix the battery pack to improve the integration of the second bracket, and the second bracket with the battery pack and the control board installed is installed in the upper rod housing, which also improves the rigidity of the upper rod assembly; 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 the control board.

[0091] It should be noted that the second bracket 400A can of course also be installed in the lower rod housing (100a, 100) to become a part of the lower rod assembly (10A, 10'). It is not limited here whether the second bracket 400A is installed inside the lower rod assembly (10A, 10') or the upper rod assembly (10B, 40). Of course, the second bracket 400A can also be installed between the lower rod assembly (10A, 10') and the upper rod assembly (10B, 40). As long as the technical solution of the second bracket 400A is installed inside the connecting rod assembly 10, it is within the protection scope of this application. It should also be noted that the specific number of the second bracket 400A is not limited here. The second bracket 400A can be set to at least one, and at least one of the first brackets 100A can be set in at least one of the lower rod assembly (10A, 10') or the upper rod assembly (10B, 40). The technical solution of at least one first bracket 100A 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 400A are simultaneously installed in the lower rod assembly (10A, 10') or the upper rod assembly (10B, 40), it is not limited here as to which of the first bracket 100A and the second bracket 400A 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 400A can achieve reliable electrical connection, as long as the first bracket 100A and the second bracket 400A are installed inside the connecting rod assembly 10, the technical solutions are within the protection scope of this application.

[0092] Furthermore, the battery pack 120 includes more than two 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 30 that drives the cleaning roller to rotate, and the control board 110 is 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 outward discharge condition, and when the external power adapter is electrically connected to the charging port, the external power adapter charges the battery pack 120 through the control board 110.

[0093] In this way, a battery pack and a control board are arranged on the second bracket, and in the connecting rod assembly, the control board is electrically connected to the water pump and a driving motor in the tractor that drives the cleaning roller to rotate, and an electrode sheet group for clamping the battery pack is arranged on the control board, so that the hinge device, the connecting rod assembly and the handle can be conveniently connected and fixed to each other, and the power supply, the circuit and the control board are integrated and installed inside the connecting rod assembly, so as to reduce the overall volume of the equipment and improve the protection and the 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 with the handle.

[0094] In one or some alternative embodiments, Figures 3 to 5 , Figures 8 to 10 As shown, the control board 110 is electrically connected to the first terminal harness 105, and the lower terminal harness 105 is provided with a lower docking terminal 105c at the end facing the hinge device 20. The lower docking terminal 105c passes through the lower port and the connecting rod assembly 10 in sequence, and is electrically connected to the connector of the hinge device 20.

[0095] In one or some alternative embodiments, Figures 3 to 5 , Figures 8 to 10 As shown, the control board 110 is also electrically connected to the second terminal harness 405, and the second terminal harness 405 is provided with a docking terminal (not marked in the drawing) at the end facing the handle 50, and the docking terminal passes through the upper port and the connecting rod assembly 10 in sequence and is electrically connected to the handle 50.

[0096] Further, such as Figures 8 to 10 As shown, the control board 110 is also electrically connected to the second terminal harness 405, and the end of the second terminal harness 405 is provided with a second upper docking terminal (not marked in the drawings), and the other end of the second terminal harness 405 is connected and passes through the second upper port and the upper rod assembly (10B, 40) in sequence, and is electrically connected to the handle 50.

[0097] In this way, a control board is set on the second bracket, and the control board is inside the connecting rod assembly. The control board is electrically connected to the outside of the connecting rod assembly, and the control board is electrically connected to the first terminal wiring harness, and the first terminal wiring harness passes through the lower port and is electrically connected to the hinge device, and the control board is electrically connected to the second terminal wiring harness, and the second terminal wiring harness passes through the upper port and is electrically connected to the handle. While conveniently and quickly docking the hinge device, the connecting rod assembly and the handle with each other, a single docking of the connecting rod assembly and the hinge device can realize the rapid docking of the circuit line connected to the connecting rod assembly and the hinge device, and a single docking of the connecting rod assembly and the handle can realize the rapid docking of the circuit line connected to the connecting rod assembly and the handle.

[0098] In one or some alternative embodiments, Figure 3 to Figure 4 , Figures 8 to 10 As shown, a flow sensor 103 is also provided on the first bracket 100A, and the flow sensor 103 is arranged between the water pump 101 and the lower port, and the flow sensor 103 is connected to the water outlet 101a and the water outlet pipe to measure the flow in the water outlet 101a. Further, the flow sensor 103 is also electrically connected to the control board 110, and the flow sensor 103 transmits the real-time flow data of the water outlet 101a of the water pump 101 back to the control board 110, and the control board 110 can adjust the control strategy of the water pump 101 in real time according to the received flow data.

[0099] In this way, after the flow sensor is set in the connecting rod assembly, the control panel can adjust the control strategy of the water pump in real time according to the flow data of the water pump, so as to make the floor scrubber more energy-saving and efficient.

[0100] In one or some optional embodiments, the control board 110 is also 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 to the display module on the handle 50 through a signal connection.

[0101] 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, and can use the temperature data measured in real time by the control panel to timely adjust the control strategy of the water pump and the drive motor, so as to make the floor scrubber more energy-saving and efficient.

[0102] In one or some alternative embodiments, Figures 1 to 5As shown, the connecting rod assembly 10 also includes an adjustment mechanism 10C, the lower end of the upper rod housing (100b, 400) is sleeved on the outside or inside of the upper end of the lower rod housing (100a, 100), and the upper rod housing (100b, 400) can slide relative to the lower rod housing (100a, 100) to adjust the total length of the connecting rod assembly 10. The adjustment mechanism 10C can allow the upper rod housing (100b, 400) and the lower rod housing (100a, 100) to be in a relatively slidable state or a locked state, and allow the connecting rod assembly 10 to become a whole that does not need to be disassembled.

[0103] In this way, the length-adjustable connecting rod assembly can meet the needs of different heights of users in the family for different holding heights of the floor washer. The user only needs to press the adjustment mechanism to slide the upper rod housing relative to the lower rod housing to easily adjust the total length of the connecting rod assembly, thereby improving the adaptability of the floor washer to family users. Of course, the total length of the connecting rod assembly can also be adjusted to a minimum in the transportation and storage of the entire floor washer and the connecting rod assembly, so as to reduce the space required for transportation or storage. When the floor washer fails, if the voice module of the handle can still accurately broadcast the fault point, the user only needs to remove the entire connecting rod assembly from the floor washer and return it to the manufacturer to replace the entire connecting rod assembly. The manufacturer will use the repaired entire connecting rod assembly as a subsequent maintenance spare part after detailed inspection at the factory. The manufacturer's customer service does not need to spend time and effort to help users remotely locate the fault point, and directly let the customer replace the entire connecting rod assembly. Even if the voice module of the handle of the faulty floor washer cannot accurately broadcast the fault point, the user can still replace the entire connecting rod assembly 10, which greatly reduces the time for users to wait for spare parts and improves user satisfaction.

[0104] In one or some alternative embodiments, Figure 4As shown, the first terminal harness 105 can automatically adjust its length as the upper rod housing (100b, 400) slides relative to the lower rod housing (100a, 100). The operation of the floor scrubber is not affected during the adjustment of 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 pulled to the longest, a small part of the middle section of the first terminal harness can still be kept in the form of a spring-shaped spiral coil. When the total length of the connecting rod assembly is pulled to the 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 be affixed with sound-absorbing foam at the same time to prevent the first terminal harness from hitting the inner walls of the upper rod housing and the lower rod housing to produce sound when the floor scrubber is pulled. At the same time, the first terminal harness with adjustable length also brings great convenience to 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, the operator can easily install / remove the aforementioned first bracket and second bracket from any end of the connecting rod assembly during assembly or maintenance. The operator can first electrically connect the first bracket and the second bracket and then install them into the connecting rod assembly in turn, or can first install the two into the connecting rod assembly and then electrically connect them.

[0105] In one or some optional embodiments, the second bracket 400A is installed in the lower rod assembly (10A, 10') and the upper rod assembly (10B, 40) can be manually separated after docking with each other; when the upper rod assembly (10B, 40) of the normally working floor scrubber is separated from the lower rod assembly (10A, 10'), the tractor 30 does not work, the upper rod assembly (10B, 40) 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 state, and the Bluetooth module can communicate with other smart terminals. Further, since the second bracket 400A is installed in the upper rod assembly (10B, 40), the control panel 110 and the battery pack 120 are installed on the second bracket 400A, when the upper rod assembly (10B, 40) of the normally working floor scrubber is separated from the lower rod assembly (10A, 10'), the upper rod assembly (10B, 40) connected to the handle 50 can naturally continue to work. When the floor scrubber fails, after eliminating the failure of the mop head and the handle, the self-check mode of the floor scrubber can be started 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 water pump and flow sensor failure are further eliminated, the user only needs to return the upper rod assembly connected to the handle to the factory for replacement without disassembly, and the floor scrubber can be used again as quickly as possible. Alternatively, when the user purchases the floor scrubber, they purchase a configuration that includes lower rod assemblies and upper rod assemblies of various lengths. When a failure occurs, the floor scrubber can be used immediately by directly replacing the faulty component by the exchange method, which will not delay the user's daily cleaning. The faulty component can be returned to the factory for repair, which improves customer satisfaction.

[0106] In one or some optional embodiments, in order to meet the different requirements of different users for the holding height of the floor scrubber in the home use scenario, multiple lower rod assemblies (10A, 10') and / or upper rod assemblies (10B, 40) of different lengths can be configured and sold together with the floor scrubber. When the connecting rod assembly 10 is configured with multiple lower rod assemblies (10A, 10') and / or upper rod assemblies (10B, 40) of different lengths, connecting rod assemblies of different lengths can be matched by replacing different combinations of lower rod assemblies and / or upper rod assemblies to meet the user's requirements for different lengths of the connecting rod assemblies.

[0107] In this way, since the lower rod assembly and upper rod assembly have built-in most of the control components of the entire floor scrubber (including control panel, water pump, flow sensor, battery pack), after first eliminating the failure of the mop head and handle, the user can simply replace the lower rod assembly and upper rod assembly by themselves when encountering any floor scrubber failure, which can immediately solve the customer's daily household cleaning needs. The replaced lower rod assembly and upper rod assembly can be returned to the manufacturer for repair, which will not delay the user's daily use and improve user satisfaction.

[0108] In one or some alternative embodiments, Figures 8 to 12 As shown, the lower rod assembly (10A, 10') also includes a first connection kit, which is detachably connected to the upper open end and the lower open end of the lower rod housing (100a, 100), respectively, and the first connection kit includes a lower rod docking sleeve 100B and a lower rod upper docking sleeve 100C: the lower rod docking sleeve 100B is connected to the lower open end, and can be quickly docked with the connecting head of the hinge device 20; the lower rod upper docking sleeve 100C is connected to the upper open end, and can be quickly docked with the upper rod assembly (10B, 40).

[0109] Further, such as Figures 3 to 5 , Figures 8 to 10 As shown, 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 docking sleeve 100B in sequence, and after passing through the lower rod assembly (10A, 10'), it is electrically connected to the connector of the hinge device 20.

[0110] Specifically, Figures 3 to 5 , Figures 8 to 10As shown, the upper open end of the lower rod shell (100a, 100) is connected with a lower rod upper docking sleeve 100C, and the lower open end of the lower rod shell (100a, 100) is connected with a lower rod lower docking sleeve 100B, and between the lower rod lower docking sleeve 100B and the lower rod upper docking sleeve 100C, a first bracket 100A is installed in the lower rod shell (100a, 100), and the first bracket 100A has openings at both ends, and one end of the first bracket 100A is provided with a lower port, and the lower port is connected to the lower rod lower docking sleeve 100B; the other end of the first bracket 100A 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 100B, and a lower rod terminal seat 100B1 is provided on the other side; the lower rod docking sleeve 100B is sleeved on the connecting head of the hinge device 20 through the opening, and is adapted to be connected with the lower port of the first bracket 100A through the lower rod terminal seat 100B1, and the lower rod terminal seat 100B1 is electrically connected to the terminal seat in the connecting head (not marked in the drawing) to connect and fix the first bracket 100A and the hinge device 20. Furthermore, an opening is provided on one side of the lower rod upper docking sleeve 100C, and a lower rod upper terminal seat is provided on the other side (not marked in the drawings); the upper rod assembly (10B, 40) includes an upper rod shell (100b, 400) and an upper rod lower docking sleeve 400B that are detachably connected to each other, and an opening is provided on one side of the upper rod lower docking sleeve 400B, and an upper rod lower docking terminal 404 is provided on the other side; the upper rod lower docking sleeve 400B is sleeved on the lower rod upper docking sleeve 100C through the opening, the lower rod upper terminal seat is adaptably connected to the upper port of the first bracket 100A, and the lower rod upper terminal seat is electrically connected to the upper rod lower docking terminal 404 of the upper rod lower docking sleeve 400B, so that the lower rod assembly (10A, 10') and the upper rod assembly (10B, 40) are connected and fixed.

[0111] In one or some alternative embodiments, Figures 8 to 12 As shown, the upper rod assembly (10B, 40) includes an upper rod shell (100b, 400) and a second connection kit; the upper rod shell (100b, 400) is hollow, and the upper rod shell 400 is open at both ends, and the upper end opening of the upper rod shell (100b, 400) is connected to the clamping part of the handle 50; the second connection kit is detachably connected to the lower end opening of the upper rod shell (100b, 400), and the second connection kit includes an upper rod lower docking sleeve 400B, and the upper rod lower docking sleeve 400B can be quickly docked with the lower rod assembly (10A, 10') at the lower rod upper docking sleeve 100C, and the docking can simultaneously realize the mechanical docking and electrical connection docking of the lower rod assembly (10A, 10') and the upper rod assembly (10B, 40).

[0112] Further, such as Fig. 9 , Fig.10 As shown, the lower port of the first bracket 100A is connected to the lower docking sleeve 100B of the lower rod; the upper port of the first bracket 100A is connected to the upper docking sleeve 100C of the lower rod. The second lower port of the second bracket 400A is connected to the lower docking sleeve 400B of the upper rod. The lower docking sleeve 100B of the lower rod is hollow, with an opening at one end and a lower terminal seat 100B1 of the lower rod at the other side; the opening of the lower docking sleeve 100B of the lower rod is sleeved on the connecting head of the hinge device 20, and is adapted to be connected with the lower port of the first bracket 100A through the lower terminal seat 100B1 of the lower rod.

When it is necessary to separate the upper rod lower docking sleeve 400B from the lower rod upper docking sleeve 100C, it is necessary to first use a tool to press the clamping end of the elastic buckle 400B1 from the corresponding hole (not marked in the drawing) of the upper rod housing 400. When the clamping end withdraws from the clamping slot, pull off the rod assembly (10A, 10') and the upper rod assembly (10B, 40) with force, thereby separating the upper rod lower docking sleeve 400B from the lower rod upper docking sleeve 100C.

[0113] In this way, the first connection kit of the lower rod assembly and the second connection kit of the upper rod assembly make the docking / separation of the upper rod assembly and the lower rod assembly easier and more convenient. After the specific fault point has been located, the upper rod assembly and the lower rod assembly that need to be returned to the factory can be quickly removed. When different users have different requirements for the grip height, home users can also replace the upper rod assembly and the lower rod assembly of the corresponding length by themselves.

The lower rod lower docking sleeve 100B 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 100B1 of the lower rod lower docking sleeve 100B, and the lower rod lower terminal seat 100B1 is adapted and fixed to the lower port of the first bracket 100A.

[0115] 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, the mechanical docking, electrical connection docking, and water connection docking of the connecting rod assembly and the hinge device can be completed by a single quick docking of the connecting rod assembly and the hinge device, which is efficient and convenient.

[0116] In one or some optional embodiments, the connecting rod is also hinged with 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.

[0117] In one or some alternative embodiments, Fig. 9 , Fig.11 , Fig.12 As shown, the end of the second bracket 400A facing the hinge device 20 is connected to a support member 407 to position and install the second bracket 400A in the upper rod housing (100b, 400). Specifically, there may be multiple support members 407, one end of which is connected to the end of the second bracket 400A facing the hinge device 20, and the other end of which is connected to the upper rod housing (100b, 400) or to the upper rod lower docking sleeve 400B. In this way, the second bracket 400A can be accurately positioned for installation in the upper rod housing (100b, 400), so as to prevent the control board 110 and the battery pack 120 installed on the second bracket 400A from shaking in the upper rod housing (100b, 400) when the user pushes or pulls the floor scrubber at high speed, thereby reducing damage to the components in the upper rod assembly (10B, 40), and providing better anti-collision protection for the components in the upper rod assembly (10B, 40) through the upper rod housing (100b, 400).

[0118] In the present application, the mechanical docking of the connecting rod assembly and the hinge device can realize the simultaneous docking of the circuit line and the water channel between the connecting rod assembly and the hinge device; which is different from the mechanical docking of the connecting rod assembly and the handle, which can only realize the simultaneous docking of the circuit line between the connecting rod assembly and the handle. In combination with the difference of the corresponding docking interfaces at the two mechanical docking locations, each docking interface itself has been fool-proofed, so the user will not make a mistake in docking the hinge device, the connecting rod assembly, and the handle, thereby avoiding the problem of incorrect installation between the various components and improving the installation efficiency of the equipment. Moreover, when an electrical connection failure occurs, if the control panel reports a connection failure of the water pump or the drive motor, then the failure may only occur in the electrical connection failure of the circuit line between the connecting rod assembly and the hinge device. If the display device of the handle has a display failure, then the electrical connection failure can only occur in the electrical connection failure of the circuit line between the connecting rod assembly and the handle. If the control panel reports a low flow rate of the water pump, in addition to the possible failure of the water pump itself, the connection of the water channel between the connecting rod assembly and the hinge device may also leak.

[0119] In the present application, since the first bracket and the second bracket are installed in the cavity of the lower rod housing and the upper rod housing, the first bracket is installed with a water pump and a flow sensor, and the second bracket is installed with a battery pack and a control panel, the cavity of the upper rod assembly and the lower rod assembly is not configured with any parts except for the first terminal harness and the second terminal harness passing through, the weight of the lower rod assembly and the upper rod assembly together is still very light, and the center of gravity of the connecting rod assembly will also make the user feel more convenient by holding the handle to push and pull the connecting rod. In this embodiment, only the mechanical docking of the lower rod assembly and the hinge device simultaneously realizes the simultaneous docking of the circuit line and the water channel between the two, while the mechanical docking of the lower rod assembly and the upper rod assembly, and the mechanical docking of the upper rod assembly and the handle only realizes the corresponding simultaneous docking of the circuit line between the two. Combined with the difference in the corresponding docking interfaces at the two mechanical docking locations, each docking interface itself has been fool-proofed, so the user will not make a mistake in docking the hinge device, the connecting rod assembly, and the handle, thereby avoiding the problem of incorrect installation between the components and improving the installation efficiency of the equipment. On the other hand, the control panel is installed in the upper rod assembly, which is set close to the handle that the user holds. Once the floor scrubber fails, it is very likely that the control panel is at fault. At this time, setting the control panel close to the handle makes it easier for the user to directly remove the upper rod assembly and return the upper rod assembly and the handle to the factory for replacement. Compared with the cumbersome removal of one or two sections of the upper rod assembly and the lower rod assembly in the prior art to repeatedly verify where the problem occurred and repeatedly compare the fault point, it is much easier. Of course, users who have purchased floor scrubbers equipped with upper rod assemblies and lower rod assemblies of various lengths 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, which will not affect the user's demand for the frequency of use of the floor scrubber for daily cleaning, thereby improving the user experience.

[0120] Second, as Figures 1 to 12As 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 circuit and control panel into the interior of the connecting rod assembly 10, thereby reducing the overall volume of the device 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 it is the end of the connecting rod assembly 10 connected to the water circuit and the circuit of the hinge device 20, or the end of the connecting rod assembly 10 connected only to the circuit of the handle 50, thereby avoiding the problem of incorrect installation between the components and improving the installation efficiency of the equipment.

[0121] like Figures 1 to 12 As shown, the present invention provides a hinge device 20 for a floor scrubber, which is used to connect a tractor head 30 and a connecting rod assembly 10 of the floor scrubber. A water pump 101, a battery 120, and a control panel 110 are arranged in the connecting rod assembly 10. A motor and a water tank for driving a cleaning roller to rotate are arranged on the tractor head 30. The water pump 101 transports clean water in the water tank to the surface of the cleaning roller and recovers sewage on the surface of the cleaning roller to the water tank. The hinge device 20 includes a rotating hinge and a connector, and the rotating hinge is hinged to the tractor head 30; the connector is detachably connected to the connecting rod assembly 10, and the connector includes an exposed portion (not shown in the drawings), and the exposed portion fixedly connects the connector and the rotating hinge at an angle; the tractor head 30, the connecting rod assembly 10, the connector, and the rotating hinge accommodate pipelines connecting the water pump and the water tank and wires electrically connected to the battery, the water pump, the control panel, and the motor.

[0122] Thus, the hinge device of the present invention for a floor scrubber includes a rotating hinge body and a connector, 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, the connector includes an exposed portion, 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 a water pump and a water tank and electric wires electrically connected to a battery, a water pump and a motor, and the docking of the water pipes and electric wires built into the hinge device with the drag head and the connecting rod assembly can be completed by 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 electric circuit, thereby improving the efficiency of maintenance and replacement of the hinge device. Compared with the prior art, the present invention realizes the connection between the connecting rod assembly of the floor scrubber and the mop head by setting a hinge device, which not only reduces the volume occupied by the hinge device in the overall floor scrubber, but also contains the pipes and water pumps for water circulation connection and the circuits connected to the water pump, power supply and control system in the connecting body and the rotating hinge body, realizing the water connection and circuit connection, facilitating the maintenance and replacement of the hinge device without damaging the internal water connection and circuit connection, and improving the maintenance and replacement efficiency of the hinge device. At the same time, the connecting rod assembly includes a lower rod assembly and an upper rod assembly whose total length can be adjusted to solve the problem of different height requirements for the length of the connecting rod assembly of the floor scrubber caused by different users in a family. 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 different from 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 adapt and install 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 connected only 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 that when the floor scrubber fails, it is difficult to disassemble the upper rod assembly and the lower rod assembly, and the two components need to be repeatedly returned to the factory for repair and replacement, which 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, thereby 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.

[0123] In one or some optional embodiments, the connecting body of the hinge device 20 includes an exposed portion and an internally connected portion (not shown in the drawings). When the floor scrubber completes the connection of 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 column wall of the internally connected portion is transitionally matched with the inner wall of the connecting rod assembly 10, and the cylindrical depth of the entire transitional match is approximately twice the diameter of the inner wall of the connecting rod assembly 10, so that the hinge device 20 and the connecting rod assembly 10 can maintain stable and consistent cooperation in the axial direction, and the concentricity and stability of the cooperation between the two can be guaranteed.

[0124] 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 the technical solutions described in the aforementioned embodiments may still be modified, or some structures (technical features) in one or more embodiments may be replaced or combined by equivalent means, and these modifications or replacements or combinations do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the 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.
