Description

[0001] This application is a divisional application of Chinese Patent Application No. 202410718541.1 entitled "A strip support, pole assembly and floor scrubber", the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of cleaning equipment technology, and more particularly to a pole assembly for a floor scrubber. Background Technology

[0003] Early floor cleaning tools used by people included brooms, mops, and floor scrubbers, which relied primarily on manual operation. With technological advancements, the demands for floor cleaning tools gradually increased, leading to the emergence of vacuum cleaners. These electric vacuum cleaners use negative pressure to suck up debris and dust from the floor. Classified by cleaning methods and the flow path of small and large debris, this type of technology is generally categorized as air-dust circulation technology. However, due to the limitations of its working principle, vacuum cleaners cannot clean some firmly attached debris and stains. Therefore, a new type of floor scrubber, the "water-dust circulation" scrubber, has emerged. This scrubber uses a motor to drive a cleaning drum to wipe the floor, and is also equipped with a water supply system and a water tank to clean the cleaning drum, thus achieving a perfect floor cleaning.

[0004] The prior art CN220175029U discloses a floor scrubber pole assembly, including a hollow pole, an upper connecting assembly, and a lower connecting assembly, as well as an upper connecting shell and a lower connecting shell. The upper end of the upper connecting shell is fixedly connected to the floor scrubber handle, and the lower end of the lower connecting shell is fixedly connected to the floor scrubber mop head. Limiting grooves are formed on the side walls of both the upper and lower ends of the pole. When the upper and lower ends of the pole are respectively inserted into the upper connecting shell and the lower connecting shell, the upper connecting shell and the lower connecting shell extend into the upper docking port of the pole. Through the corresponding cooperation of the upper connecting assembly, the upper connecting shell, the lower connecting assembly, and the lower connecting shell, the upper and lower ends of the pole are securely connected to the floor scrubber handle and the mop head, respectively.

[0005] However, the existing "water and dust circulation" floor scrubbers inevitably occupy a large volume of space, whether the scrubber pole assembly is located at the bottom of the water tank or on the machine body. In addition, in order to power the scrubber pole assembly, it is necessary to extend the scrubber pole assembly to an adapter module that can be easily accessed for power. When users remove or place the water tank or perform maintenance on the scrubber body, water will inevitably drip onto the adapter module used to access the power of the scrubber pole assembly.

[0006] Therefore, a good solution needs to be found to perfectly integrate the power supply, water pump, control board, and other components of the floor scrubber into the scrubber's pole assembly. Summary of the Invention

[0007] To overcome the limitations of existing technologies, this invention provides a pole assembly for a floor scrubber. By integrating several components, including the power supply, water pump, control board, and flow sensor, as well as the water pipes connecting the water tank and cleaning roller, onto a strip-shaped bracket of the pole assembly, and then installing the assembled strip-shaped bracket assembly inside the pole assembly, the volume of the floor scrubber pole assembly is reduced. This also prevents external damage to the pole assembly's circuit components, water pipes, and electrical circuits during water tank removal or machine maintenance. Furthermore, by incorporating the strip-shaped bracket within the floor scrubber pole assembly, this invention enhances the rigidity and strength of the pole assembly, and improves the portability of installing and disassembling the internal components.

[0037] In a second aspect, the present invention provides a floor scrubbing machine, including a mop head, a hinge device, a handle, and the rod assembly described in the first aspect.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] 1. The strip bracket of the present invention is detachably installed inside the hollow pole. On the one hand, it increases the rigidity of the pole itself in the pole assembly of the floor scrubber. On the other hand, the strip bracket of the present invention is open at the top and closed at the bottom, forming a semi-closed cylindrical semi-box shape. The strip bracket is equipped with a water pump, battery pack and control board. After disconnecting the pole assembly from the mop head and handle of the floor scrubber, the strip bracket can be taken out from any end of the hollow pole to operate the water pump, battery pack and control board. It is convenient and quick, and improves the portability of the installation and disassembly of the built-in components of the floor scrubber pole assembly.

[0040] 2. This invention integrates several components, including the power supply, water pump, control board, and flow sensor, as well as the water pipes connecting the water tank and cleaning roller, onto a strip bracket of the pole assembly. The assembled strip bracket assembly is then installed inside the pole assembly, thereby reducing the volume of the floor scrubber pole assembly. This also solves the problem of damage to the circuit components, water pipes, and electrical circuits inside the hollow pole assembly caused by external moisture, dust, and airborne particles when the floor scrubber is being removed from or placed in the water tank or when the machine is being maintained.

[0041] 3. The present invention also improves the rigidity of the floor scrubber pole assembly by setting a strip bracket installed inside the floor scrubber pole assembly, thereby improving the portability of the installation and disassembly of the built-in components of the floor scrubber pole assembly.

[0042] 4. At least one rod assembly with a built-in strip support is connected to the mop head 30 and handle 50 of the floor scrubber, so as to realize the lightweight and modular design of the floor scrubber.

[0043] 5. The floor scrubber of the present invention includes a mop head, a hinge device, a handle, and a pole assembly. The lower end of the pole assembly is connected to the hinge device, which is hinged to the mop head. The upper end of the pole assembly is connected to the handle. The detachable pole assembly further reduces the volume of the floor scrubber pole assembly, and also reduces the packaging volume required for the entire floor scrubber when the mop head, pole assembly, and handle are disassembled and packaged separately. This further protects the various components of the floor scrubber from greater impacts during transportation when the scrubber is assembled into a whole. The flexibly detachable floor scrubber allows several components, including the power supply, water pump, control board, and flow sensor, to be centrally mounted on a strip bracket. With the display module on the handle, users can quickly locate the faults of each component, facilitating user self-removal and replacement of faulty parts from the strip bracket. This improves the convenience of user self-repair of the floor scrubber, facilitates the manufacturer's rapid provision of good spare parts, and enhances the user experience of using the floor scrubber.

[0067] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. The present invention will be further described below with reference to specific embodiments, but these are not intended to limit the present invention.

[0068] Firstly, such as Figures 4 to 11As shown, a strip-shaped bracket 100A of the present invention is connected within a hollow rod 100 and serves as the rod assembly for a floor scrubber. The rod assembly has a mop head 30 and a handle 50 for connecting to the floor scrubber at both ends. The top of the strip-shaped bracket 100A is open, and both ends of the strip-shaped bracket 100A have a lower interface 100A2 and an upper interface 100A1, respectively. A water pump 101, a battery pack 120, and a control board 110 can be installed on the strip-shaped bracket 100A through the open end. The water pump 101 has a water outlet 1. 01a and inlet 101b are respectively connected to outlet pipe and inlet pipe (not shown in the attached figure); the battery pack 120 and control board 110 can be installed on the strip bracket 100A from the opening, and the control board 110 is electrically connected to the water pump 101 and battery pack 120 and controls the operation of the water pump 101; by disconnecting the rod assembly from the tow head 30 and handle 50, and then taking the strip bracket 100A out of the hollow rod 100, the water pump 101, battery pack 120 and control board 110 can be operated.

[0069] Furthermore, one end of the strip bracket 100A is provided with a lower interface 100A2, which faces the connector 20A of the hinge device 20, and the hinge device 20 is hinged to the mop head 30 of the floor scrubber; the other end of the strip bracket 100A is provided with an upper interface 100A1, which faces the handle 50; at least one rod assembly is connected to the mop head 30 and handle 50 of the floor scrubber, realizing the lightweight and modular design of the floor scrubber.

[0070] Specifically, such as Figures 4 to 7 As shown, a water pump 101 is provided on the strip support 100A and is located on the side of the strip support 100A near the lower interface 100A2. The water pump 101 is provided with an outlet 101a and an inlet 101b. The outlet 101a and the inlet 101b are respectively connected to an outlet pipe and an inlet pipe (not shown in the attached figure).

[0071] Specifically, such as Figures 7 to 11 As shown, the outlet 101a and the inlet 101b are both oriented toward the hinge device 20. The outlet 101a and the inlet 101b are respectively provided with an outlet pipe and an inlet pipe. The outlet pipe and the inlet pipe pass through the rod assembly and are connected to the connector 20A of the hinge device 20 to form a water channel connecting the rod assembly and the hinge device 20.

[0072] Thus, a water pump 101 is installed on the strip bracket 100A. The outlet 101a and inlet 101b of the water pump 101 are both oriented towards the hinge device 20. This allows the water outlet and inlet pipes connecting the outlet 101a, inlet 101b, and hinge device 20 to pass through the rod assembly and connect to the connector 20A of the hinge device 20. This minimizes the length of the water pipes inside the rod assembly and makes the connection more convenient. At the same time, a single docking between the rod assembly and the hinge device 20 enables the rapid docking of the water channels connecting the rod assembly and the hinge device 20.

[0073] In one or more alternative embodiments, such as Figures 2 to 11 As shown, a flow sensor 103 is also provided on the strip support 100A. The flow sensor 103 is located between the water pump 101 and the lower interface 100A2. One of the water outlet pipe and the water inlet pipe is connected to the flow sensor 103, and the other of the water outlet pipe and the water inlet pipe passes through the lower interface 100A2 and exits the strip support 100A.

[0074] In one or more alternative embodiments, such as Figures 2 to 11 As shown, the flow sensor 103 connects the outlet 101a and the outlet pipe to measure the flow rate within the outlet 101a. Furthermore, the flow sensor 103 is also electrically connected to the control board 110. The flow sensor 103 transmits the real-time flow data from the outlet 101a of the water pump 101 back to the control board 110, and the control board 110 adjusts the control strategy for the water pump 101 in real time based on the received flow data.

[0075] Thus, within the pole assembly, the flow sensor 103 allows the control board 110 to adjust the control strategy for the water pump 101 in real time based on the flow data of the water pump 101, enabling the floor scrubber to work more energy-efficiently and effectively.

[0076] In one or more alternative embodiments, such as Figures 2 to 11 As shown, a battery pack 120 and a control board 110 are also provided on the strip bracket 100A. The battery pack 120 is located on the side of the strip bracket 100A near the upper interface 100A1. The control board 110 is threaded onto the fixing nut post (not shown in the figure) of the strip bracket 100A. The control board 110 is provided with an electrode plate group (not shown in the figure), which clamps the battery pack 120. The strip bracket 100A and the control board 110 together fix the battery pack 120 to improve the integration of the strip bracket 100A. Furthermore, the battery pack 120 includes two or more batteries connected in series and then in parallel.

[0077] In a preferred embodiment, the battery 120 is placed inside the pole assembly as a power source. By setting the strip bracket 100A, the pole assembly can be easily disassembled and installed, and the battery 120 can also be easily replaced and repaired.

[0078] In some specific embodiments, the control board 110 is electrically connected to the water pump 101 and the drive motor (not shown in the figure) that drives the cleaning roller inside the mop head 30 to rotate, and the control board 110 is also electrically connected to the charging port (not shown in the figure) of the handle 50. While the control board 110 controls the operation of the water pump 101 and the drive motor, the battery pack 120 is in a state of external discharge. 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.

[0079] Thus, the battery pack 120 and control board 110 are installed on the strip bracket 100A. Inside the rod assembly, the control board 110 is electrically connected to the water pump 103 and the drive motor inside the tractor head 30 that drives the cleaning roller to rotate. The control board 110 is equipped with an electrode plate group for clamping the battery pack, which can easily connect and fix the hinge device 20, the rod assembly and the handle 50 to each other, and integrate the power supply, circuit and control board 110 inside the rod assembly, reducing the overall size of the equipment and improving protection and ease of installation and disassembly. At the same time, a single docking between the rod assembly and the hinge device 20 can realize the rapid docking of the circuit lines connecting the rod assembly and the hinge device 20, and a single docking between the rod assembly and the handle 50 can realize the rapid docking of the circuit lines connecting the rod assembly and the handle 50.

[0080] In one or more alternative embodiments, such as Figure 7 As shown, the control board 110 is also provided with at least one temperature sensor 111. The temperature sensor 111 senses the temperature of the control board 110 and the battery pack 20, and feeds it back to the display unit (not shown in the figure) provided on the surface of the handle 50 through a signal connection.

[0081] Thus, the control board 110 is also equipped with at least one temperature sensor 111, which allows the control board 110 to obtain the temperature of the battery pack 120 and the control board 110 in real time. The control board 110 can then adjust the control strategy of the water pump 103 and the drive motor in a timely manner based on the temperature data measured in real time, so that the floor scrubber can work more energy-efficiently and efficiently.

[0082] In one or more alternative embodiments, the strip bracket 100A is provided with a fixing part (not shown in the figures) for limiting the water pump 101, so that the water pump 101 will not move during use. It should be noted that, since the pole assembly of a floor scrubber, such as one using this strip bracket 100A, may slip and fall to the ground during use, the water pump 101 needs to have good stability and not move.

[0083] In one or more alternative embodiments, the fixing part includes at least one annular sleeve (not shown in the figure) disposed on the strip bracket 100A, and the annular sleeve has a surrounding angle of more than 180°, and the water pump 101 is housed in the annular sleeve.

[0084] In some specific embodiments, the aforementioned fixing part can take the form of a ring-shaped buckle, which is made of an elastic material. This allows the ring-shaped buckle to be opened during the installation of the water pump 101, and the water pump to be installed inside. The elastic material's resilience then allows the ring-shaped buckle to retain its position. To ensure proper installation and prevent it from falling off easily, the ring-shaped buckle needs to be designed according to the shape of the water pump 101, so that it can surround the water pump by at least 180°.

[0085] In other specific embodiments, the aforementioned fixing part may also adopt other structures, such as... Figures 4 to 6 As shown, it includes at least one first fixing member 100A3 disposed on a strip bracket 100A, a water pump 101 is housed between the first fixing member 100A3 and the strip bracket 100A, and the first fixing member 100A3 has an extension surface that is at least partially in contact with the water pump 101.

[0086] Furthermore, the aforementioned fixing part may also adopt other structures, including at least one first fixing member 100A3 disposed on the strip bracket 100A and a second fixing member (not shown in the figure) connected to the first fixing member 100A3, the water pump 101 being accommodated between the first fixing member 100A3 and the second fixing member, and the second fixing member having an extension surface that at least partially conforms to the water pump 101.

[0087] The first fixing member 100A3 and the second fixing member are connected by a detachable or rotatable connection.

[0088] For example, the first fixing component 100A3 is a fixing nut post, and the second fixing component is a fixing plate with through holes. During installation, the fixing plate is installed onto the fixing nut post with screws, and the water pump 101 can be limited by the fixing plate. Of course, snap-fit ​​structures such as male and female snap-fit, magnetic structures, and clamp structures can also be used.

[0089] As can be seen, there are many structures that can achieve the above-mentioned fixation of the water pump 101 and facilitate disassembly and assembly. The above structures are only some exemplary examples and should not be regarded as limiting the scope of protection of this invention.

[0090] In one or more alternative embodiments, the strip support 100A is provided with a sensor fixing part (not shown in the figure) for limiting the flow sensor 103.

[0091] In one or more alternative embodiments, the sensor fixing part has a shape adapted to the flow sensor 103 so that the flow sensor 103 can be engaged with the sensor fixing part. That is, the strip bracket 100A is provided with a groove (not shown in the figure) adapted to the shape of the flow sensor 103, and the groove has at least one U-shaped latch, which limits the water inlet end and / or water outlet end of the flow sensor 103.

[0092] In some specific embodiments, the sensor fixing part may also adopt other structures, such as including at least one third fixing member (not shown in the figure) disposed on the strip bracket 100A and a fourth fixing member (not shown in the figure) detachably connected or rotatably connected to the third fixing member, with the flow sensor 103 housed between the third fixing member and the fourth fixing member.

[0093] Specifically, the third and fourth fixing components can adopt the structure described above, as long as they can fix the flow sensor 103.

[0094] In one or more alternative embodiments, the rod body further includes a lower mating sleeve 100B detachably connected to the lower mating interface 100A2, and an upper mating sleeve 100C detachably connected to the hollow rod 100 located at one end of the upper mating interface 100A1, wherein the lower mating sleeve 100B is detachably connected to the hollow rod 100 located at one end of the lower mating interface 100A2.

[0095] In one or more alternative embodiments, such as Figure 2 , Figure 7 , Figure 11 As shown, the hollow rod 100 has a guide rib 100a extending axially along its side wall, and the strip bracket 100A has a guide groove (not shown in the figure) at its bottom. The guide groove can slide on the guide rib 100a to allow the strip bracket 100A to slide into and out of the hollow rod 100.

[0096] In some specific embodiments, such as Figure 7As shown, the control board 110 is electrically connected to at least one lower terminal harness 105. The lower terminal harness 104 has a lower docking terminal 104 at its end. The lower docking terminal 104 extends out of the lower docking interface 100A2 of the strip bracket 100A and engages with the lower terminal seat 100B1 of the lower docking sleeve 100B, thereby allowing the control board 110 to be electrically connected to the mop head 30 to control the motor that drives the floor scrubber cleaning roller to rotate (not shown in the attached figure). The control board 110 is also electrically connected to at least one upper terminal harness 106. The end of the upper terminal harness 106 is provided with an upper docking terminal 107. The upper docking terminal 107 extends out of the upper docking interface 100A1 of the strip bracket 100A and engages with the upper terminal seat (not shown in the figure) of the upper docking sleeve 100C. This allows the control board 110 to interact and communicate with the display unit, voice unit (not shown in the figure), charging unit (not shown in the figure), and touch unit (not shown in the figure) in the handle 50 in real time, so as to make the floor scrubber work more energy-efficiently and efficiently.

[0097] Thus, the control board 110 is electrically connected to the mop head 30 and the handle 50 through the lower terminal harness 105 and the upper terminal harness 106, so that the strip bracket 100A installed in the hollow rod 100 can control other electrical components in the mop head 30 and the handle 50 through the control board 110, so that the floor scrubber can work more energy-efficiently, intelligently and efficiently.

[0098] In one or more alternative embodiments, such as Figure 1 , Figure 2 , Figure 11 As shown, the rod assembly includes at least two rods (lower rod 10 and upper rod 40), each rod being connected sequentially. In the rod (lower rod 10) closest to the tractor head 30, one of the water outlet pipe and water inlet pipe inside the rod passes through the lower docking interface 100A2, exits the strip bracket 100A, and exits the lower docking sleeve 100B to connect with the tractor head 30 for water connection. The other of the water outlet pipe and water inlet pipe inside the rod 10 passes through the upper docking interface 100A1, exits the strip bracket 100A. The upper connecting sleeve 100C passes through and connects with another rod (upper rod 40) corresponding to the rod (lower rod 10), realizing the water channel connection between the two rods; a water outlet pipe or water inlet pipe is also provided in the rod 10 near the towing head 30, one end of the water outlet pipe or water inlet pipe passes through the lower connecting interface 100A2 of the rod 10 and connects with the water channel of the towing head 30, and the other end passes through the upper connecting interface 100A1 of the rod 10 and connects with the water channel of the other rod 40.

[0099] In this way, each pole can be effectively connected into a complete pole assembly through at least one pole. The pole assembly can then be quickly assembled into a complete floor scrubber by connecting it to the scrubbing head and handle. The easily disassembled pole assembly reduces the size of the conventional floor scrubber body and simultaneously prevents external damage to the pole assembly's circuit components, water lines, and electrical circuits when removing or placing the water tank or performing maintenance on the machine body. By incorporating a strip bracket within the floor scrubber pole assembly, the rigidity of the pole assembly is improved, and the portability of installing and disassembling the internal components of the floor scrubber pole assembly is enhanced.

[0112] It should be noted that, in addition to floor scrubbers, the strip bracket 100A and / or rod assembly in the various embodiments of the present invention can also be applied to other industrial or mechanical equipment, such as glass and wall cleaning equipment or other handheld cleaning equipment.

[0113] Example 4

[0114] Fourthly, the present invention provides an embodiment of a floor scrubbing machine, such as... Figure 1 , Figure 2 , Figure 11 As shown, the floor scrubber includes a connecting rod and a mop head 30 connected to the connecting rod. The connecting rod includes at least one rod assembly, a hinge device 20, a rod assembly, and a handle 50; the hinge device 20 includes a connector 20A and a hinge joint 20B, the hinge joint 20B being hinged to the mop head 30; the handle 50 is located away from the mop head 30 and has a locking portion and a gripping portion (not shown in the figure).

[0115] The rod assembly is detachably connected between the hinge device 20 and the handle 50. The hinge device 20, the rod assembly, and the handle 50 can be quickly connected in sequence. The water channels (not shown in the attached diagram) built into the hinge device 20 and the rod assembly are simultaneously connected when the hinge device 20 and the rod assembly are connected. The circuits (not shown in the attached diagram) built into the hinge device 20, the rod assembly, and the handle 50 are simultaneously connected when the hinge device 20, the rod assembly, and the handle 50 are connected.
