Description

[0001] This application is a divisional application of Chinese Patent Application No. 202410718483.2 entitled "A Detachable Bracket, 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 and 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 body, an upper connecting component, and a lower connecting component, 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 body. When the upper and lower ends of the pole body 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 body. Through the corresponding cooperation of the upper connecting component, the upper connecting shell, the lower connecting component, and the lower connecting shell, the upper and lower ends of the pole body are securely connected to the floor scrubber handle and the mop head, respectively.

[0005] However, the existing "water and dust circulation" floor scrubbers, whether the scrubber pole assembly is located at the bottom of the water tank or on the machine body, inevitably occupy a large volume. 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, it is necessary to find a good solution to perfectly integrate the power supply, water pump, control board and other components of the floor scrubber into the floor scrubber pole assembly. Summary of the Invention

[0007] To overcome the limitations of existing technologies, this invention provides a detachable bracket for a floor scrubber pole assembly. This bracket 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 the detachable bracket. The assembled detachable bracket is then installed inside the pole assembly, reducing its size and preventing external damage to the pole assembly's circuitry, water supply, and electrical systems during water tank removal or maintenance. Furthermore, the detachable bracket within the pole assembly enhances its rigidity and improves the ease of installation and removal of its internal components.

[0030] In a second aspect, the present invention provides a floor scrubbing machine, including a mop head, a hinge device, a handle, and a pole assembly as described in the first aspect.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. The detachable 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 detachable bracket of the present invention is a semi-closed cylindrical semi-box shape with an open top and a closed bottom. The detachable bracket is equipped with a water pump, a battery pack and a control board. After disconnecting the pole assembly from the scrubber's mop head and handle, the detachable bracket can be taken out from any end of the hollow pole to operate the water pump, battery pack and control board. This is convenient and quick, and improves the portability of the installation and disassembly of the built-in components of the floor scrubber pole assembly.

[0033] 2. This invention integrates several components of the floor scrubber, 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 detachable bracket of the upright assembly. The assembled detachable bracket assembly is then installed inside the upright assembly. This reduces the size of the floor scrubber upright assembly and prevents damage to the circuit components, water pipes, and electrical circuits inside the hollow pole of the upright assembly from 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.

[0034] 3. The detachable bracket assembly of the present invention mounts several components, including a power supply, water pump, control board, and flow sensor, onto the detachable bracket. The detachable bracket assembly, after mounting all components, is placed inside a hollow rod. A lower connecting sleeve and an upper connecting sleeve are then connected to both ends of the hollow rod. The strength and rigidity of the upright formed by the detachable bracket assembly, hollow rod, lower connecting sleeve, and upper connecting sleeve are thus enhanced. The strength and rigidity of the upright assembly formed by at least one upright connected in sequence are also enhanced. During the logistics process of users returning faulty uprights and manufacturers providing new uprights, the internal strength and rigidity of the upright are also enhanced. This also facilitates the protection of the several components mounted on the detachable bracket during logistics, ensuring that the components are protected by the detachable bracket, hollow rod, lower connecting sleeve, and upper connecting sleeve, preventing damage to the parts during logistics.

[0035] 4. The pole assembly of the present invention includes at least two sets of poles that are sequentially connected to each other. At least one pole has a detachable bracket assembly inside which several components, including a power supply, water pump, control board, and flow sensor, are installed. The lower end of the pole assembly is connected to a hinge device, which is hinged to the mop head. The upper end of the pole assembly is connected to a 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 when the floor scrubber is assembled into a whole during transportation.

[0036] 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 detachable floor scrubber allows several components, including the power supply, water pump, control board, and flow sensor, to be centrally mounted on a detachable bracket. With the display module on the handle, users can quickly locate the faults of each component, facilitating user self-repair of the faulty component from the detachable 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.

[0060] 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.

[0061] Firstly, such as Figure 2 , Figures 4 to 11 As shown, this invention discloses a detachable bracket 10z, which is detachably installed inside a hollow rod 100 for use in the upright assembly of a floor scrubber. The upright assembly includes at least one upright, and the upright includes a hollow rod 100 in which the detachable bracket 10z is built-in. The upright assembly connects the floor scrubber's mop head 30 and handle 50. The detachable bracket 10z is a semi-enclosed cylindrical semi-box shape with an open top and a closed bottom. The two ends of the detachable bracket 10z are respectively provided with a lower port 10a1 and an upper port 10b1. The detachable bracket 10z is equipped with a water pump 101, a battery pack 120, and a control board 110. The control board 110 is electrically connected to the water pump 101 and the battery pack 120 and controls the operation of the water pump 101. By disconnecting the upright assembly from the mop head 30 and handle 50, and then removing the detachable bracket 10z from either end of the hollow rod 100, the water pump 101, battery pack 120, and control board 110 can be operated.

[0062] Specifically, such as Figure 2 , Figure 6 As shown, a water pump 101 is provided on the detachable bracket 10z and is located on the side of the detachable bracket 10z near the lower port 10a1. 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).

[0063] Furthermore, both the outlet 101a and the inlet 101b are 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 upright assembly and are connected to the connector 20A of the hinge device 20 to form a water channel connecting the upright assembly and the hinge device 20.

[0064] Thus, a water pump 101 is installed on the detachable bracket 10z. 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 upright assembly and connect to the connector 20A of the hinge device 20. This minimizes the length of the water pipes inside the upright assembly and makes the connection more convenient. At the same time, a single docking between the upright assembly and the hinge device 20 enables the rapid docking of the water channels connecting the upright assembly and the hinge device 20.

[0065] In one or more alternative embodiments, a flow sensor 103 is also provided on the detachable bracket 10z. The flow sensor 103 is located between the water pump 101 and the lower port 10a1. 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 port 10a1 and exits the detachable bracket 10z.

[0066] In one or more alternative embodiments, the flow sensor 103 is connected to 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, and transmits the real-time flow data from the outlet 101a of the water pump 101 back to the control board 110. The control board 110 adjusts the control strategy for the water pump 101 in real time based on the received flow data.

[0067] 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.

[0068] In one or more alternative embodiments, the detachable bracket 10z is further provided with a battery pack 120 and a control board 110. The battery pack 120 is located on the side of the detachable bracket 10z near the lower port 10a1. The control board 110 is threadedly connected to the fixing nut post (not shown in the figure) of the detachable bracket 10z. The control board 110 is provided with an electrode plate group (not shown in the figure). The electrode plate group clamps the battery pack 120. The detachable bracket 10z and the control board 110 jointly fix the battery pack 120 to improve the integration of the detachable bracket 10z.

[0069] In a preferred embodiment, the battery 120 is placed inside the pole assembly as a power source. By providing a detachable bracket 10z, the pole assembly can be easily disassembled and installed, while also facilitating the replacement and maintenance of the battery 120.

[0070] In some specific embodiments, 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 (not shown in the figure) inside the mop head 30 that drives the cleaning roller to rotate. 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 discharging. 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.

[0071] Thus, the detachable bracket 10z is equipped with a battery pack 120 and a control board 110. Inside the pole 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 that holds the battery pack, which can easily connect and fix the hinge device 20, the pole assembly, and the handle 50 to each other. The power supply, circuit, and control board 110 are integrated and installed inside the pole 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 pole assembly and the hinge device 20 can quickly connect the circuit lines connecting the pole assembly and the hinge device 20, and a single docking between the pole assembly and the handle 50 can quickly connect the circuit lines connecting the pole assembly and the handle 50.

[0072] In one or more alternative embodiments, such as Figure 10 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.

[0073] 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.

[0074] In one or more alternative embodiments, the detachable bracket 10z is provided with a fixing part for limiting the water pump 101 so that the water pump 101 will not move during use. It should be noted that, since the upright assembly of a floor scrubber, such as one using the detachable bracket 10z, may slip and fall to the ground during use, the water pump 101 needs to have good stability and not move.

[0075] In one or more alternative embodiments, the fixing part includes at least one annular sleeve (not shown in the figure) disposed on the detachable bracket 10z, and the annular sleeve has a surrounding angle of more than 180°, and the water pump 101 is housed in the annular sleeve.

[0076] 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°.

[0077] In other specific embodiments, the aforementioned fixing part may also adopt other structures, such as... Figure 8 As shown, it includes at least one first fixing member 100A3 disposed on a detachable bracket 10z, a water pump 101 is housed between the first fixing member 100A3 and the detachable bracket 10z, and the first fixing member 100A3 has an extension surface that at least partially conforms to the water pump 101.

[0078] Furthermore, the aforementioned fixing part may also adopt other structures, including at least one first fixing member 100A3 disposed on the detachable bracket 10z 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.

[0079] The first fixing member 100A3 and the second fixing member are connected by a detachable connection or a rotatable connection.

[0080] 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.

[0081] 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.

[0082] In one or more alternative embodiments, the detachable bracket 10z is provided with a sensor fixing part (not shown in the figure) for limiting the flow sensor 103.

[0083] 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 detachable bracket 10z 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.

[0084] 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 detachable bracket 10z 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.

[0085] Specifically, the third and fourth fixing components can adopt the structure described above, as long as they can fix the flow sensor 103.

[0086] In one or more alternative embodiments, the upright pole further includes a lower connecting sleeve 100B detachably connected to the lower port 10a1, and an upper connecting sleeve 100C detachably connected to the hollow rod 100 located at one end of the upper port 10b1, wherein the lower connecting sleeve 100B is detachably connected to the hollow rod 100 located at one end of the lower port 10a1.

[0087] In one or more alternative embodiments, the hollow rod 100 has a guide rib 100a extending axially along its side wall, and the detachable bracket 10z 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 detachable bracket 10z to slide in and out of the hollow rod 100.

[0088] In one or more alternative embodiments, such as Figure 2 , Figure 3 , Figure 12 , Figure 13As shown, the control board 110 is electrically connected to at least one lower terminal harness 105. The lower terminal harness 105 has a lower docking terminal 104 at its end. The lower docking terminal 104 extends out of the lower port 10a1 of the detachable bracket 10z 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's 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 port 10b1 of the detachable bracket 10z 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.

[0089] 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 detachable bracket 10z 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.

[0090] In one or more alternative embodiments, such as Figure 1A , Figure 1B , Figure 2 As shown, the pole assembly includes at least two poles (10, 40), each pole being connected sequentially. In the pole 10 closest to the tractor head 30, one of the water outlet pipe and water inlet pipe inside the pole 10 passes through the detachable bracket 10z from the lower port 10a1 and through the lower connecting sleeve 100B to connect with the tractor head 30 in a water circuit. The other of the water outlet pipe and water inlet pipe inside the pole 10 passes through the detachable bracket 10z from the upper port 10b1. The upper connecting sleeve 100C passes through and connects with another upright 40 corresponding to the upright 10, realizing the water channel connection between the two uprights; a water outlet pipe or water inlet pipe is also provided in the upright 10 near the towing head 30, one end of the water outlet pipe or water inlet pipe passes through the lower port 10a1 of the upright 10 and connects with the water channel of the towing head 30, and the other end passes through the upper port 10b1 of the upright 10 and connects with the water channel of the other upright 40.

[0091] In this way, each upright can be effectively connected into a complete upright assembly through at least one upright pole. The upright assembly can then be connected to the scrubbing head and handle to quickly assemble a complete floor scrubber. The easily detachable upright assembly reduces the size of the conventional floor scrubber body and simultaneously prevents external damage to the upright 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 detachable bracket within the upright assembly, the rigidity of the upright assembly is enhanced, and the portability of its internal components for installation and removal is improved.

[0092] In one or more alternative embodiments, such as Figure 4 , Figure 5 As shown, the detachable bracket 10z includes a first bracket 10a and a second bracket 10b that can be connected to / separated from each other, and the water pump 101 is installed on one of the first bracket 10a and the second bracket 10b.

[0093] In one or more alternative embodiments, such as Figure 4 , Figure 5 As shown, the other of the first bracket 10a and the second bracket 10b is equipped with a battery pack 120 or a control board 110.

[0094] Furthermore, such as Figure 2 , Figure 3 , Figure 12 , Figure 13 As shown, a circuit connection is also provided between the first bracket 10a and the second bracket 10b, and the circuit connection includes the circuit connection between the water pump 101, the control board 110, and the battery assembly 120.

[0095] Furthermore, such as Figures 4 to 11 As shown, when manufacturing a floor scrubber, the manufacturer can arrange to first assemble the empty first bracket 10a and second bracket 10b into an empty detachable bracket 10z. Then, the water pump 101, flow sensor 103, control board 110, inlet pipe, and outlet pipe are installed on the empty detachable bracket 10z to assemble the detachable bracket assembly 10Z. The entire detachable bracket assembly 10Z is then pushed into the hollow rod 100, and the lower connecting sleeve 100B and upper connecting sleeve 100C are connected to both ends of the hollow rod 100 to complete the installation of a complete upright. Of course, as... Figure 6 As shown, when manufacturing floor scrubbers, manufacturers can arrange to first assemble the empty first bracket 10a and second bracket 10b into first bracket assembly 10A and second bracket assembly 10B respectively, and then mechanically connect, electrically connect, and water connect the first bracket assembly 10A and second bracket assembly 10B to complete the assembly of the entire detachable bracket assembly 10Z.

[0096] Thus, by designing the detachable brackets as interconnectable and separable first and second brackets, the assembly sequence of various components can be flexibly arranged during the manufacturing process, improving the overall assembly efficiency of the pole. Furthermore, when internal components of the pole are damaged, users can easily remove the corresponding first and second brackets, replace the damaged parts, and reinstall the detachable brackets into the hollow pole themselves. After accurately locating the faulty component, users only need to notify the manufacturer to provide the corresponding spare part, reducing waste in the transportation process, improving the efficiency of after-sales service for the floor scrubber, and minimizing unnecessary logistics waste and damage during transit.

[0097] Furthermore, such as Figures 4 to 6 , Figure 10 , Figure 11 As shown, the first bracket 10a is provided with a first mounting part 10a2 at one end pointing to the second bracket 10b, and the second bracket 10b is provided with a second mounting part 10b2 at one end pointing to the first bracket 10a. The first bracket 10a and the second bracket 10b are detachably connected through the mutual cooperation of the first mounting part 10a2 and the second mounting part 10b2.

[0098] Specifically, such as Figure 4 , Figure 6 , Figure 10 , Figure 11 As shown, the first mounting part 10a2 can be a U-shaped structure with two protruding nut posts (not shown in the figure) on the inner wall of the first bracket 10a pointing towards the second bracket 10b. The second mounting part 10b2 can be a U-shaped structure with two concave posts (not shown in the figure) on the outer wall of the second bracket 10b pointing towards the first bracket 10a. The two concave posts can be sleeved on the two protruding nut posts to achieve a firm connection between the first bracket 10a and the second bracket 10b.

[0099] Furthermore, such as Figure 4 , Figure 6 , Figure 10 , Figure 11 As shown, at least one of the two concave pillars has a through hole (not shown in the figure) on its upper surface opposite to the two protruding nut pillars. After the first bracket 10a and the second bracket 10b are firmly connected, the first bracket 10a and the second bracket 10b can be further connected by screws through the through hole on at least one of the two protruding nut pillars.

[0100] Of course, the connection method between the first bracket 10a and the second bracket 10b described above is only one of the ways to achieve a reliable connection between the two. Other methods such as snap-fit, plug-in, bolt-fit, pin-fit, and hinge-fit will not be described in detail again. All technical solutions that can achieve a detachable connection between the first bracket 10a and the second bracket 10b are within the protection scope of this application.

[0101] In this way, the detachable brackets are designed as first and second brackets that can be connected / separated from each other, and the connection between the two is further enhanced by using a socket and screw connection method. This makes it easier for users to remove the corresponding first and second brackets from the pole and then replace the damaged parts.

[0102] In some specific embodiments, such as Figure 2 , Figure 12 , Figure 13 As shown, the control board 110 is electrically connected to at least one lower terminal harness 105. The lower terminal harness 105 has a lower docking terminal 104 at its end. The lower docking terminal 104 extends out of the lower port 10a1 of the detachable bracket 10z 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 port 10b1 of the detachable bracket 10z 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.

[0103] 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 detachable bracket 10z 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.

[0104] Example 1

[0105] like Figures 6 to 13As shown, a water pump 101 is provided on the detachable bracket 10z and is located on the side of the detachable bracket 10z near the lower port. The water pump 101 has an outlet 101a and an inlet 101b, and the outlet 101a and the inlet 101b are respectively connected to an outlet pipe and an inlet pipe. The outlet 101a and the inlet 101b are both arranged in the direction of 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 upright assembly and are connected to the connector 20A of the hinge device 20 to form a water channel connecting the upright assembly and the hinge device 20.

[0106] The detachable bracket 10z is also equipped with a flow sensor 103, which is located between the water pump 101 and the lower port. 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 port and exits the detachable bracket 10z.

[0107] The detachable bracket 10z is also equipped with a battery pack 120 and a control board 110. The battery pack 120 is located on the side of the detachable bracket 10z near the lower port 10a1. The control board 110 is threaded to the fixing nut post (not shown in the attached figure) of the detachable bracket 10z. The control board 110 is equipped with an electrode plate group (not shown in the attached figure). The electrode plate group clamps the battery pack 120. The detachable bracket 10z and the control board 110 together fix the battery pack 120.

[0108] 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.

[0109] The detachable bracket 10z is equipped with a fixing nut post for limiting the water pump 101 and a fixing plate with a through hole. The fixing plate has an extension surface that at least partially mates with the water pump 101. During installation, the fixing plate is installed onto the fixing nut post with screws, thereby limiting the water pump 101.

[0110] The detachable bracket 10z is provided with a groove that is adapted to the shape of the flow sensor 103, and the groove has at least one U-shaped bayonet, which limits the water inlet and outlet of the flow sensor 103.

[0111] Example 2

[0112] Secondly, the present invention provides an embodiment of a detachable bracket assembly, such as... Figure 2 , Figures 6 to 12As shown, the detachable bracket assembly 10Z includes a detachable bracket 10z, a water pump 101, a battery pack 120, and a control board 110. The water pump 101 is installed on the detachable bracket 10z near the lower port 10a1, providing power for the floor scrubber to lift water. The battery pack 120 is installed on the detachable bracket 10z near the upper port 10b1, providing power for the floor scrubber to operate. The control board 110 covers the battery pack 120 and is electrically connected to the water pump 101 and the battery pack 120, controlling the operation of the water pump 101. The specific structure of the detachable bracket 10z can be found in the detailed technical solution described in the first aspect above, and will not be repeated here.

[0113] It should be noted that, in addition to floor scrubbers, the detachable bracket 10z and / or detachable bracket assembly 10Z in the various embodiments of the present invention can also be applied to other industrial or mechanical equipment, such as glass, wall cleaning equipment or other handheld cleaning equipment.

[0114] Example 3

[0115] Thirdly, the present invention provides an embodiment of a pole assembly, such as... Figure 1A , Figure 1B , Figure 2 , Figure 3 , Figure 6 , Figure 12 , Figure 13 As shown, the pole assembly includes at least two sets of poles that are sequentially connected to each other, and at least one detachable bracket assembly as described in the second aspect. The detachable bracket assembly can be installed inside at least one of the poles. Specifically, the pole assembly includes a lower pole 10 and an upper pole 40, and the detachable bracket 10z is disposed inside the lower pole 10 or the upper pole 40. Specifically, the inner detachable bracket 10z disposed inside the lower pole 10 serves as a support and connection unit for the internal components of the lower pole 10, so as to realize the integrated installation of water channels, electrical circuits and power supplies within the lower pole 10; the inner detachable bracket 10z placed inside the lower pole 10 also supports the inner wall of the lower pole 10, thereby increasing the structural strength and rigidity of the lower pole 10.

[0116] Furthermore, the lower rod 10 includes a hollow rod housing 100, a detachable bracket 10z disposed within the hollow rod housing 100, and a lower docking sleeve 100B and an upper docking sleeve 100C connected to both ends of the hollow rod housing 100. The upper rod 40 includes an upper rod housing (not shown in the attached figure) and an upper rod lower docking sleeve (not shown in the attached figure). The upper rod 40 also includes an upper rod lower terminal wiring harness (not shown in the attached figure), and the end of the upper rod lower terminal wiring harness is provided with an upper rod lower docking terminal (not shown in the attached figure). The upper rod lower docking terminal realizes electrical connection with the display unit, voice unit, charging unit, and touch unit (not shown in the attached figure) within the handle 50.

[0117] It should be noted that, in addition to floor scrubbers, the detachable brackets and / or pole assemblies 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.

[0118] Example 4

[0119] Fourthly, the present invention provides an embodiment of a floor scrubbing machine, as shown in Figure 1. Figure 2 As shown in Figure 1, the floor scrubber includes a mop head 30, a hinge device 20, a handle 50, and a pole assembly as described in the third aspect. The lower end of the pole assembly is connected to the hinge device 20, which is hinged to the mop head 30. The hinge device 20 includes a connector 20A and a hinge joint 20B. The connector 20A engages with the pole assembly, and the hinge joint 20B is hinged to the mop head 30. The handle 50 is located away from the mop head 30 and has a engaging portion 50A and a gripping portion 50B.

[0120] The upright assembly is detachably connected between the hinge device 20 and the handle 50, and the hinge device 20, the upright assembly, and the handle 50 can be quickly connected in sequence; the water channels built into the hinge device 20 and the upright assembly (not shown in the attached figure) are synchronously connected when the hinge device 20 and the upright assembly are connected; the circuit lines built into the hinge device 20, the upright assembly, and the handle 50 (not shown in the attached figure) are synchronously connected when the hinge device 20, the upright assembly, and the handle 50 are connected.

[0121] Thus, this invention reduces the overall size of the equipment by connecting and fixing the hinge device, the upright assembly, and the handle together, and integrating the power supply, circuit, water circuit, and control board inside the upright assembly, thereby improving protection and ease of installation and disassembly. Simultaneously, the connection channel between the upright assembly and the hinge device accommodates the electrical wiring and water circuit connecting the water pump and the hinge device. In contrast, the connection channel between the upright assembly and the handle only accommodates the electrical circuit connecting the water pump and the handle. During installation, users can correctly install the hinge device, upright assembly, and handle by distinguishing whether the upright assembly is connected to both the water circuit and electrical circuit of the hinge device or only to the electrical circuit of the handle, thus avoiding incorrect installation of components and improving installation efficiency.

[0122] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions or combinations can be made to some structures (technical features) in one or more embodiments. Such modifications or substitutions 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 embodiments of the present invention, unless the possibility of substituting or combining structures (technical features) in different embodiments is explicitly excluded in the embodiments, or such substitutions or combinations are contrary to the overall concept of the invention.
