Description

[0001] This application is a divisional application of Chinese Patent Application No. 202421587922.2 entitled "A Connector and Link Assembly", the contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of cleaning equipment technology, and in particular to a connector and linkage assembly. 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 it is also equipped with a water supply system and a water tank to clean the cleaning drum, thus achieving a perfect floor cleaning.

[0004] However, the existing "water and dust circulation" floor scrubbers inevitably use relatively long connecting rods, whether they are located at the bottom of the water tank or on the machine body. Usually, the connecting rod is divided into multiple sections, and each section is connected by a connecting part. The connecting part needs to ensure a good connection effect, and at the same time, the power modules of each section of the connecting rod need to be connected. Utility Model Content

[0021] In one or more alternative embodiments, the connecting part is provided with screws to thread the connecting part to the second rod body, thereby achieving a detachable connection between the connecting part and the second rod body.

[0022] In one or more alternative embodiments, the screw can be connected to the second link from the axial connection joint, so that the screw remains inside the second link after fastening.

[0042] Compared with the prior art, the beneficial effects of this utility model are:

[0043] This invention features an elastic locking assembly within the receiving cavity of the connector. This assembly includes a fixing member, a pressing member, and an elastic member. Under the elastic force of the elastic member, the pressing member slides along the sliding groove of the fixing member and extends out of the opening in the receiving cavity to lock into place with the mating connector. This achieves a quick and secure connection between the connector and the mating connector, ensuring easy and fast installation without the need for additional power mechanisms, thus saving energy and costs. Under external force, the pressing member compresses the elastic member and can be fully contained within the sliding groove, allowing for quick and easy disconnection of the connector and the mating connector.

[0044] In existing technology, when a connecting rod is divided into multiple segments, this connector and mating head are applicable to existing connecting rods. By setting a circuit connector within the connecting cavity of the connector, when the pressing part snaps into the mating head, the circuit connector and the mating head are electrically connected simultaneously. This allows for simultaneous mechanical and electrical connections between multiple connecting rod segments. The connector, in conjunction with the mating head, ensures a good connection effect and also allows for the connection of the electrical modules for each connecting rod segment, making it convenient to use. When the pressing part is disconnected from the mating head, the circuit connector is also disconnected from the mating head, thus simultaneously disconnecting the mechanical and electrical connections between multiple connecting rod segments, making it convenient and quick to use.

The present invention will be further described below with reference to specific embodiments, but these are not intended to limit the present invention.

[0063] First aspect

[0064] See Figures 1-5 This application provides a connector for fitting a mating head and for use in a cleaning device. To prevent the rods of the cleaning device from being too long, the cleaning device divides the rods into a first connecting rod 400 and a second connecting rod 100. The first connecting rod 400 is connected to the connector 400B, and the second connecting rod 100 is connected to the mating head 100C. The first connecting rod 400 and the second connecting rod 100 are detachably connected through the detachable connection between the connector 400B and the mating head 100C.

[0065] See Figure 4 , Figures 6-8 The connector 400B includes a resilient snap-fit ​​assembly, a circuit connector 401, and a mating portion 400B4. The mating portion 400B4 has independent receiving cavities 400B6 and at least one connecting cavity 400B7. The circuit connector 401 is disposed in the connecting cavity 400B7. The connector 100C has a circuit mating part 107 at the position corresponding to the circuit connector 401, and the circuit mating part 107 can be electrically connected to the circuit connector 401. The elastic snap-fit ​​assembly includes a fixing member 400B1, a pressing member 400B3, and an elastic member 400B2. The fixing member 400B1 is accommodated in a receiving cavity 400B6. The fixing member 400B1 is provided with a sliding groove (not shown in the figure). The pressing member 400B3 can slide along the sliding groove. The receiving cavity 400B6 is provided with an opening corresponding to the sliding groove (not shown in the figure). At least part of the pressing member 400B3 can extend out of the opening. The elastic member 400B2 is provided in the sliding groove, and both ends of the elastic member 400B2 abut against the pressing member 400B3 and the receiving cavity 400B6, respectively.

[0066] When connecting the first link 400 and the second link 100, firstly, an external force is applied. Under this force, the pressing member 400B3 compresses the elastic member 400B2, and the elastic member 400B2 is in a compressed state, while the pressing member 400B3 is fully accommodated in the sliding groove. Then, the mating connector 100C is fitted over the connector 400B, and the external force is released. In the absence of external force, the pressing member 400B3, under the elastic force of the elastic member 400B2, gradually extends out of the opening from the sliding groove and engages with the external mating connector 100C. The elastic member 400B2 remains compressed throughout, and the pressing member 400B3 remains engaged with the mating connector 100C due to the elastic force of the elastic member 400B2. This achieves the purpose of quick docking between the connector 400B and the mating connector 100C, ensuring a reliable connection, convenient and quick installation, and eliminating the need for other power mechanisms, thus saving energy and costs. When the pressing part 400B3 engages with the connector 100C, the first connecting rod 400 and the second connecting rod 100 are connected. Simultaneously, the circuit connector 107 and the circuit connection part 401 are electrically connected. By using this connector 400B in conjunction with the connector 100C, a good connection effect can be ensured, and the electrical modules of each connecting rod segment can also be connected, making it convenient to use.

[0067] When it is necessary to disconnect the first link 400 and the second link 100, an external force is applied. Under the action of this external force, the pressing member 400B3 compresses the elastic member 400B2, and the pressing member 400B3 is fully accommodated in the sliding groove. Then, the connector 400B and the mating member 100C can be disconnected, achieving the purpose of quickly disconnecting the connector 400B and the mating member 100C. Disassembly is convenient and quick. At the same time as disconnecting the first link 400 and the second link 100, the circuit mating member 107 and the circuit connector 401 are also disconnected, making it convenient and quick to use.

[0068] In this application, by setting the connector 400B, quick docking with the mating connector 100C can be achieved, ensuring a good connection effect. While connecting the first link 400 and the second link 100, the electrical connection between the circuit mating part 107 and the circuit connector 401 can also be achieved simultaneously, enabling circuit continuity. The structure is simple and the design ingenious, simultaneously achieving both mechanical and electrical connections between the first link 400 and the second link 100.

[0069] In one specific embodiment, see [reference] Figure 6 and Figure 8 The connector 400B also includes a limiting post 400B8, which is located in the receiving cavity 400B6. An elastic element 400B2 is sleeved on the limiting post 400B8, and the height of the limiting post 400B8 should not affect the complete accommodating of the pressing element 400B3 within the sliding groove. To prevent the elastic element 400B2 from detaching from the sliding groove during use due to elastic force, the limiting post 400B8 limits the elastic element 400B2, ensuring it provides elastic force to the pressing element 400B3, allowing it to extend out of the opening and achieve the snap-fit ​​effect between the pressing element 400B3 and the connector 100C. Here, the elastic element 400B2 can be a spring, as is used in the prior art.

[0070] In one specific embodiment, see [reference] Figure 6 and Figure 8 The fastener 400B1 has a snap-fit ​​groove (not shown in the figure) on at least one side, and the receiving cavity 400B6 has a guide post 400B9 corresponding to the snap-fit ​​groove. When installing the fastener 400B1, the side of the fastener 400B1 with the snap-fit ​​groove faces the guide post 400B9, and the fastener 400B1 is pushed so that the snap-fit ​​groove can slide relative to the guide post 400B9 until the snap-fit ​​groove engages with the guide post 400B9, the fastener 400B1 is installed in place, and it can achieve a stable connection effect.

[0071] In one specific embodiment, see [reference] Figure 4 , Figures 6-8The connector 400B also includes a mating portion 400B5 coaxially arranged with the mating portion 400B4, which can be connected to the external first connecting rod 400. A screw (not shown in the figure) can be installed on the mating portion 400B5 to thread the mating portion 400B5 to the first connecting rod 400, thus achieving a detachable connection between the mating portion 400B5 and the first connecting rod 400. This connection is reliable and facilitates installation and disassembly. Furthermore, the screw can be axially connected between the mating portion 400B5 and the first connecting rod 400. After tightening, the screw will remain inside the first connecting rod 400, and the user cannot directly see the screw from the non-open end face. This provides protection against forced disassembly and theft, improving the overall stability of the device.

[0072] Second aspect

[0073] Based on the same inventive concept, see [reference] Figures 1-4 This application also provides a linkage assembly that can be used in a cleaning device with a mop head. The linkage assembly includes a first link 400, a second link 100, a connector 100C, and a connector 400B as described in the first aspect. The first link 400 and the connector 400B form a first linkage assembly 40, and the second link 100 and the connector 100C form a second linkage assembly 10. The first link 400 is connected to the connector 400B, and the second link 100 is connected to the connector 100C. The connector 400B can be snapped into the connector 100C by an elastic snap-fit ​​assembly, thereby achieving the connection between the first link 400 and the second link 100, which is convenient.

[0074] In one specific embodiment, see [reference] Figures 1-4 The outer diameter of the first connecting rod 400 is larger than the outer diameter of the connector 400B, and the outer diameter of the second connecting rod 100 is larger than the outer diameter of the mating connector 100C. When the first connecting rod 400 is connected to the connector 400B, and the second connecting rod 100 is connected to the mating connector 100C, and the connector 400B and the mating connector 100C are engaged, the first connecting rod 400 and the second connecting rod 100 can be connected to form a shape as shown in the image. Figure 1 The form shown achieves concealed installation, that is, the first link 400 and the second link 100 are respectively sleeved on the outside of the connector 400B and the mating head 100C. The outer walls of the first link 400 and the second link 100 are not provided with other connecting structures, and the appearance is simple and beautiful. When the user uses the cleaning device containing this link assembly for cleaning, the simple appearance can ensure that the cleaning device can be used normally under space-constrained conditions.

[0075] In one specific embodiment, see [reference] Figure 7The connector 100C has an opening on the side facing the connector 400B, through which it fits onto the connector 400B. The connector 100C includes a circuit mating member 107 and at least one mating cavity 100C3. The at least one mating cavity 100C3 corresponds to at least one connecting cavity 400B7. The circuit mating member 107 is located in the mating cavity 100C3 and can be electrically connected to the circuit connector 401. The connector 100C has a slot (not shown in the figure), into which the pressing member 400B3 can be engaged. The shape of the slot is adapted to the shape of the pressing member 400B3.

[0076] In use, when connecting the first link 400 and the second link 100, firstly, the first link 400 and the second link 100 are connected to the connector 400B and the mating head 100C respectively (of course, this process can be completed during the first assembly of the link assembly); under the action of external force, the pressing member 400B3 compresses the elastic member 400B2, the elastic member 400B2 is in a compressed state, and the pressing member 400B3 is completely accommodated in the sliding groove; then, the mating head 100C is sleeved on the outside of the connector 400B. At this time, the external force is released. Under the action of the elastic force of the elastic member 400B2, the pressing member 400B3 gradually extends out of the opening of the sliding groove and is engaged in the slot, realizing the engagement of the mating head 100C and the connector 400B, thereby realizing the connection of the first link 400 and the second link 100, and simultaneously realizing the electrical connection of the circuit mating member 107 and the circuit connecting member 401. By setting a slot that matches the shape of the pressing part 400B3, the connection stability between the connector 100C and the connector 400B can be improved, thereby ensuring the reliable connection between the first link 400 and the second link 100.

[0077] In one specific embodiment, see [reference] Figure 3 and Figure 6 The connector 100C has a first hole 100C2 corresponding to the slot, and the first connecting rod 400 has a second hole (not shown in the figure) corresponding to the first hole 100C2. When the first connecting rod 400 is connected to the connector 400B, and the connector 400B is engaged with the connector 100C, the first hole 100C2 and the second hole form a channel (not shown in the figure) so that an external force transmission mechanism can extend into the channel and act on the pressing member 400B3. When it is necessary to separate the connector 400B from the connector 100C, a tool (i.e., an external force transmission mechanism) needs to be used to insert into the channel through the second hole corresponding to the first connecting rod 400 and press the pressing member 400B3. After the pressing member 400B3 is removed from the slot, the user can pull the first connecting rod 400 and the second connecting rod 100 to separate the first connecting rod 400 and the second connecting rod 100.

[0078] In one specific embodiment, see [reference] Figures 1-4The linkage assembly also includes a grip assembly 50 and a hinge rod 20. The grip assembly 50 is connected to the first linkage 400. Specifically, the grip assembly 50 includes a locking portion 50A, a grip portion 50B, and a display panel (not shown). The locking portion 50A is connected to the first linkage 400, the grip portion 50B facilitates user gripping, and the display panel can display the operating parameters of the cleaning device connected to the linkage assembly. One end of the hinge rod 20 is connected to the second linkage 100, and the other end of the hinge rod 20 can be connected to the mop head 30 of the cleaning device. Specifically, the hinge rod 20 includes a connecting portion 20A and a hinge portion 20B. The connecting portion 20A is connected to the second linkage 100, and the hinge portion 20B is hinged to the mop head 30.

[0079] In one specific embodiment, see [reference] Figure 4 The first link 400 and the second link 100 are hollow inside. The link assembly also includes a mounting bracket 100A. The two ends of the mounting bracket 100A are respectively provided with a lower port 100A1 and an upper port 100A2. The lower port 100A1 of the mounting bracket 100A faces the connecting part 20A.

[0080] It should be noted that the specific installation location of the mounting bracket 100A is not limited here. The mounting bracket 100A can be installed within the first connecting rod 400, or it can be installed within the second connecting rod 100. Alternatively, the mounting bracket 100A can span both the first and second connecting rods 400, meaning a portion of the mounting bracket 100A is located on the first connecting rod 400, and another portion is located on the second connecting rod 100. Furthermore, the specific number of mounting brackets 100A is not limited here; at least two mounting brackets 100A can be provided, with at least one mounting bracket 100A each within the first and second connecting rods 400 and 100, respectively.

[0081] Furthermore, taking the mounting bracket 100A installed in the second link 100 as an example, the mounting bracket 100A should be adapted to the hollow shape inside the second link 100 so that the mounting bracket 100A placed inside the second link 100 will not slide or fall off when the cleaning device is working. The mounting bracket 100A installed inside the second link 100 serves as a support and connection unit for the internal components of the link assembly, and can realize the integrated installation of water channels, electrical lines and power supplies within the link assembly (which will be explained in detail later). Since the second link 100 is hollow, the mounting bracket 100A placed inside the second link 100 supports the inner wall of the second link 100 to increase the structural strength and rigidity of the second link 100, thereby reducing the overall weight of the link assembly while further increasing the rigidity of the link assembly.

[0082] In one specific embodiment, see [reference] Figure 4 , Figure 9 and Figure 10 The linkage assembly also includes a water pump 101 mounted on the mounting bracket 100A, and an inlet pipe (not shown) and an outlet pipe (not shown) mounted on the hinge rod 20. The water pump 101 is located near the lower port 100A1 of the mounting bracket 100A. The water pump 101 has an outlet 101a and an inlet 101b, both of which face the hinge rod 20. The pipes of the outlet 101a and the inlet 101b pass through the lower port 100A1 and are connected to the outlet pipe and the inlet pipe, respectively. The inlet pipe and the outlet pipe are connected to the tow head 30, thereby forming a water passage connecting the linkage assembly and the tow head 30.

[0083] In this application, by setting a water pump 101 on the mounting bracket 100A, with the outlet 101a and inlet 101b of the water pump 101 facing the hinge rod 20, it is easy for the water pump 101 and the connecting part 20A to form a connected water channel. This allows the length of the water channel inside the linkage assembly to be minimized and the connection to be more convenient. At the same time, a single docking of the second link 100 and the hinge rod 20 can achieve rapid docking of the water channel.

[0084] In one specific embodiment, see [reference] Figure 4 , Figure 9 and Figure 10 The linkage assembly also includes a power supply 120 and a control panel 110 mounted on a mounting bracket 100A. The power supply 120 is located near the upper port 100A2 of the mounting bracket 100A and may include two or more batteries connected in series followed by parallel. The control panel 110 is threaded onto the mounting bracket 100A via a fixing nut post (not shown). The control panel 110 is electrically connected to the water pump 101 and a drive motor (not shown) inside the tractor head 30. This drive motor drives the cleaning roller (not shown) of the tractor head 30 to rotate, and the control panel 110 is also electrically connected to the power supply 120. During the operation of the water pump 101 and the drive motor controlled by the control panel 110, the power supply 120 is in a discharging state. The control panel 110 has an electrode assembly (not shown) that clamps the power supply 120. The mounting bracket 100A and the control panel 110 can jointly fix the power supply 120 to improve the integration of the mounting bracket 100A.

[0085] Furthermore, the grip component 50 is provided with a charging port (not shown in the figure), which is electrically connected to the control panel 110. When the external power adapter is electrically connected to the charging port, the external power adapter charges the power supply 120 through the control panel 110.

[0086] In this application, after the grip assembly 50, the first connecting rod 400, the second connecting rod 100, and the hinge rod 20 are sequentially connected and fixed, the power supply 120 and the control panel 110 are integrated and installed inside the connecting rod assembly, reducing the overall size of the equipment and improving protection and ease of installation and disassembly. Simultaneously, a single connection between the second connecting rod 100 and the hinge rod 20 enables rapid connection of their electrical circuitry, and a single connection between the first connecting rod 400 and the grip assembly 50 also enables rapid connection of their electrical circuitry.

[0087] In one specific embodiment, see 3 and Figure 4 The control panel 110 is electrically connected to a first wire 105. A first wire connector 104 is provided at the end of the first wire 105. The first wire connector 104 extends out of the lower port 100A1 and is electrically connected to the connection part 20A of the hinge rod 20. The control panel 110 is also electrically connected to a second wire 106, which is electrically connected to the grip assembly 50.

[0088] Thus, a control panel 110 is installed on the mounting bracket 100A. The control panel 110 is electrically connected to the first wire 105 and the second wire 106. The first wire 105 passes through the lower port 100A1 and is electrically connected to the hinge rod 20. The second wire 106 is electrically connected to the grip assembly 50. This allows for quick and easy docking of the hinge rod 20, the first connecting rod 400, the second connecting rod 100, and the grip assembly 50, while also enabling rapid docking of the electrical circuits. This allows for quick docking of the internal interconnected electrical circuits of each component of the linkage assembly (hinge rod 20, second connecting rod 100, first connecting rod 400, and grip assembly 50) with a single docking.

[0089] In one specific embodiment, see 3. Figure 4 , Figure 9 and Figure 10 The mounting bracket 100A is also equipped with a flow sensor 103, which is located between the water pump 101 and the lower port 100A1. The flow sensor 103 is connected to the outlet 101a to measure the flow rate in the outlet 101a. The flow sensor 103 is also electrically connected to the control panel 110. The flow sensor 103 transmits the real-time measured flow rate data of the outlet 101a back to the control panel 110. The control panel 110 can adjust the water volume control strategy of the water pump 101 in real time based on the received flow data, so that the floor scrubber can work more energy-efficiently and effectively.

[0090] In one specific embodiment, see [reference] Figure 4The mounting bracket 100A is also equipped with at least one temperature sensor 111. The temperature sensor 111 is used to sense the temperature of the water pump 101 and the power supply 120, and feeds it back to the display panel set on the grip assembly 50 through a signal connection. After the display panel obtains the temperature of the water pump 101 and the power supply 120 in real time, the control panel 110 can adjust the control strategy of the water pump 101 and the drive motor in a timely manner so that the floor scrubber can work more energy-efficiently and efficiently.

[0091] In one specific embodiment, see [reference] Figure 3 and Figure 4 The second link assembly 10 also includes a connecting sleeve 100B disposed on the second link 100. The connecting sleeve 100B is hollow inside, and a snap-fit ​​seat 100B1 is provided at the upper end of the connecting sleeve 100B. The end of the connecting part 20A of the hinge rod 20 is provided with a snap-fit ​​docking part, an inlet interface, and an outlet interface (not shown in the figure). The inlet interface is connected to the inlet pipe, and the outlet interface is connected to the outlet pipe. When the mounting bracket 100A is disposed inside the second link 100, and the connecting sleeve 100B is sleeved on the connecting part 20A of the hinge rod 20, the end of the connecting part 20A extends into the connecting sleeve 100B. The inlet interface and the outlet interface are respectively connected to the pipes of the inlet 101b and the outlet 101a, and the snap-fit ​​docking part snaps into the snap-fit ​​seat 100B1.

[0092] Furthermore, a fastening screw (not shown in the figure) is provided on the connecting sleeve 100B. This fastening screw enables a threaded connection between the connecting sleeve 100B and the second rod 100, thus achieving a detachable connection between them. The connection is reliable and easy to install or disassemble. The fastening screw can axially connect the second rod 100 and the connecting sleeve 100B. After tightening, the fastening screw remains inside the second rod 100, and the user cannot directly see it from the non-open end face. This provides protection against forced disassembly and theft, improving the stability of the entire linkage assembly and even the cleaning device.

[0093] The connecting sleeve 100B enables a detachable connection between the second link 100 and the hinge rod 20, making the connection between the hinge rod 20 and the second link 100 more stable and improving the structural stability. Simultaneously, a single, quick docking between the second link 100 and the hinge rod 20 can efficiently and conveniently complete mechanical, electrical, and waterway connections.

[0094] See in this application. Figures 1 to 5The first link 400 and the second link 100 are detachably connected between the hinge rod 20 and the grip assembly 50. The water pump 101, control panel 110, and power supply 120 are integrated and installed via a mounting bracket 100A. The grip assembly 50 controls the water pump 101 to supply water to the mop head 30 and controls the power supply 120 to supply power to the water pump 101 and drive motor for cleaning operations.

[0095] After the gripping assembly 50, the first connecting rod 400, the second connecting rod 100, and the hinge rod 20 are sequentially connected, the water channels of the water pump 101, the hinge rod 20, and the towing head 30 can be synchronously connected, and the electrical circuits of the towing head 30, the hinge rod 20, the second connecting rod 100, the first connecting rod 400, and the gripping assembly 50 can be synchronously connected. This application enables the gripping assembly 50, the first connecting rod 400, the second connecting rod 100, and the hinge rod 20 to be interconnected and fixed, and integrates the power supply 120, the control panel 110, the water channels, and the electrical circuits into the entire linkage assembly, reducing the overall size of the equipment and improving protection and ease of installation and disassembly.

[0096] The following describes in detail the differences in the installation positions of components related to the mounting bracket 100A in different embodiments, based on the specific installation position of the mounting bracket 100A.

[0097] Example 1

[0098] See Figure 3 and Figure 4 The second connecting rod 100 has an inner cavity, and the mounting bracket 100A is located in the inner cavity of the second connecting rod 100. The lower end of the second connecting rod 100 has a connecting sleeve 100B. The lower port 100A1 of the mounting bracket 100A is connected to the connecting sleeve 100B. Specifically, the upper end of the connecting sleeve 100B has a snap-fit ​​seat 100B1, which is adapted to the lower port 100A1 of the mounting bracket 100A. The snap-fit ​​seat 100B1 can be adapted and connected to the lower port 100A1 of the mounting bracket 100A.

[0099] See Figures 4-6The connector 400B's mating portion 400B4 has only one connecting cavity 400B7, which houses the circuit connector 401. To form a complete circuit, a third wire 402 is provided inside the first connecting rod 400 for electrically connecting the circuit connector 401 and the grip assembly 50. The control panel 110 mounted on the mounting bracket 100A electrically connects the first wire 105 and the second wire 106. The end of the first wire 105 is provided with a first wire connector 104, which extends out of the lower port 100A1 and can be electrically connected to the connecting portion 20A of the hinge rod 20. The second wire 106 extends out of the upper port 100A2 and is electrically connected to the circuit mating member 107. After the grip assembly 50, the first link 400, the second link 100, and the hinge rod 20 are sequentially connected, the first wire connector 104 is electrically connected to the connection part 20A of the hinge rod 20; the circuit connector 107 is electrically connected to the circuit connector 401, so that the second wire connector 106 is sequentially electrically connected to the circuit connector 107, the circuit connector 401, and the third wire 402, and is electrically connected to the grip assembly 50.

[0100] In this embodiment, refer to Figure 1 , Figure 2 and Figure 4 The water pump 101's outlet 101a and inlet 101b pipes pass through the lower port 100A1 and are connected to the inlet pipe and outlet pipe respectively. The inlet pipe and outlet pipe are connected to the towing head 30, thus forming a water channel connecting the linkage assembly and the towing head 30.

[0101] See Figure 4 , Figure 6 and Figure 7 In order to ensure the stability of the mounting bracket 100A, the connector 100C is provided with a joint 100C1 on the side facing the mounting bracket 100A. The joint 100C1 can be adapted and connected to the upper port 100A2 of the mounting bracket 100A.

[0102] In this embodiment, refer to Figure 4 Since the mounting bracket 100A is installed in the inner cavity of the second link 100, and the inner cavity of the first link 400 is not equipped with any other parts except for the third wire 402, the weight of the second link 100 will exceed the weight of the first link 400, thus making the overall center of gravity of the link assembly lower, and the user will feel more convenient when pushing and pulling the tractor head 30 by holding the grip assembly 50.

[0103] In this embodiment, the mechanical docking of the second link 100 and the hinge rod 20 simultaneously achieves the synchronous docking of their electrical circuits and water channels. The mechanical docking of the second link 100 and the first link 400, and the mechanical docking of the first link 400 and the gripping component 50, only achieve the synchronous docking of their respective electrical circuits. Due to the differences in the docking interfaces at the two mechanical docking points, each interface has been designed to prevent incorrect docking between the hinge rod 20, the second link 100, the first link 400, and the gripping component 50. This avoids incorrect installation of components and improves the installation efficiency of the equipment.

[0104] Example 2

[0105] Compared to the aforementioned Embodiment 1, in this embodiment, the mounting bracket 100A is located within the inner cavity of the first connecting rod 400. The connector 400B and the mating connector 100C require adjustment, differing slightly from Embodiment 1. The mating portion 400B4 of the connector 400B is provided with two independent connecting cavities 400B7. One connecting cavity 400B7 is used to accommodate the circuit connector 401, and the other connecting cavity 400B7 is used to accommodate the pipes of the water pump 101's outlet 101a and inlet 101b. The two independent connecting cavities 400B7 ensure water and electricity separation, resulting in high safety. Correspondingly, the mating connector 100C is provided with two independent mating cavities 100C3. One mating cavity 100C3 corresponds to the connecting cavity 400B7 accommodating the circuit connector 401 and is used to accommodate the circuit connector 107. The other mating cavity 100C3 is used for the passage of the water pump 101's outlet 101a and inlet 101b pipes.

[0106] The circuitry and water channels in this embodiment differ slightly from those in Embodiment 1. The control panel 110 is electrically connected to the first wire connector 104 via a first wire 105. The first wire connector 104 passes sequentially through the lower port 100A1 and the inner cavity of the second connecting rod 100, and is electrically connected to the connection portion 20A of the hinge rod 20. The control panel 110 is directly electrically connected to the grip assembly 50 via a second wire 106. The pipes of the water pump 101's outlet 101a and inlet 101b pass sequentially through the lower port 100A1 and the inner cavity of the second connecting rod 100, respectively connecting to the inlet and outlet pipes. The electrical wiring harness and water connection pipe located at the lower end of the mounting bracket 100A need to pass through the entire cavity of the second connecting rod 100, resulting in a longer connection distance from the hinge rod 20 to this wiring harness and water pipe. Other technical details are completely consistent with Embodiment 1 and will not be repeated here.

[0107] In this embodiment, the center of gravity of the linkage assembly is higher than in Embodiment 1. Therefore, the user's experience when holding the grip assembly 50 and pushing / pulling the mop head 30 will differ somewhat from that in Embodiment 1. Both Embodiment 1 and Embodiment 2 integrate the power supply 120, electrical wiring, water channels, and control panel 110 inside the linkage assembly, making full use of its internal volume. Compared to placing these components outside the linkage assembly, this results in a simpler external structure, ensuring normal operation of the linkage assembly with the cleaning device even under space-constrained conditions, and improving protection and ease of installation and disassembly.

[0108] Example 3

[0109] Compared with the aforementioned embodiments one and two, in this embodiment, the mounting bracket 100A is located between the first connecting rod 400 and the second connecting rod 100. Since the mounting bracket 100A is longer, the length of the mounting bracket 100A in conjunction with the first connecting rod 400 and the second connecting rod 100 is longer than that in embodiments one and two. The stability of the connection between the first connecting rod 400 and the second connecting rod 100 through the mounting bracket 100A is higher. Other technical details are completely consistent with the aforementioned embodiments one and two, and will not be repeated here.

[0110] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 this utility model, 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 utility model.
