Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a connector and a connecting rod assembly. Background Art

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

[0003] However, the connecting rod of the existing "water-dust circulation" floor scrubber is inevitably a longer connecting rod, whether it is set at the bottom of the water tank or on the body. The connecting rod is usually divided into multiple sections, and each section is connected by a connecting part. The connecting part needs to ensure a good connection effect, and the power modules of each section of the connecting rod must also be connected. Utility Model Content

[0063] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention. The present invention is further described below in conjunction with specific embodiments, but is not used as a limitation of the present invention.

[0064] First aspect

[0065] See also Figure 1-Figure 5 The present application provides a connecting head for sleeve connection with a docking head and used in conjunction with the docking head in a cleaning device. In order to prevent the rod of the cleaning device from being too long, the cleaning device divides the rod into a first connecting rod 400 and a second connecting rod 100. The first connecting rod 400 is connected to the connecting head 400B, and the second connecting rod 100 is connected to the docking head 100C. The detachable connection between the connecting head 400B and the docking head 100C is achieved.

[0066] See also Figure 4 , Figure 6-Figure 8 The connector 400B includes an elastic snap-fit ​​assembly, a circuit connector 401 and a docking portion 400B4, wherein the docking portion 400B4 is provided with a mutually independent accommodation cavity 400B6 and at least one connection cavity 400B7. The circuit connector 401 is provided in the connection cavity 400B7, and a circuit docking member 107 is provided at a position of the docking head 100C corresponding to the circuit connector 401, and the circuit docking member 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 the accommodating 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 accommodating cavity 400B6 is provided with an opening (not shown in the figure) corresponding to the sliding groove. 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 the two ends of the elastic member 400B2 respectively abut the pressing member 400B3 and the accommodating cavity 400B6.

[0067] When the first connecting rod 400 and the second connecting rod 100 need to be connected, first, an external force is applied, under the action of which, the pressing piece 400B3 compresses the elastic piece 400B2, the elastic piece 400B2 is in a compressed state, and the pressing piece 400B3 is completely contained in the sliding groove; then, the docking joint 100C is sleeved on the outside of the connecting head 400B, and the external force is released. In the state without external force, the pressing piece 400B3 gradually extends out of the opening of the sliding groove under the elastic force of the elastic piece 400B2, and is engaged with the external docking joint 100C, and the elastic piece 400B2 is always kept in a compressed state, and the pressing piece 400B3 is always engaged with the docking joint 100C by virtue of the elastic force of the elastic piece 400B2. The purpose of quick docking of the connecting head 400B and the docking joint 100C is achieved, the connection is reliable, the installation is convenient and quick, and no other power mechanism is required, saving energy and cost. When the pressing member 400B3 is engaged with the docking head 100C, the first connecting rod 400 and the second connecting rod 100 are connected, and at the same time, the circuit docking member 107 and the circuit connecting member 401 are electrically connected. By providing the connector 400B and cooperating with the docking head 100C, a good connection effect can be ensured, and the power modules of each section of the connecting rod can also be connected, which is convenient to use.

[0068] When it is necessary to disconnect the first connecting rod 400 and the second connecting rod 100, an external force is applied. Under the action of the external force, the pressing piece 400B3 compresses the elastic piece 400B2, and the pressing piece 400B3 is completely accommodated in the sliding groove. Then, the connecting head 400B can be disconnected from the docking head 100C, so as to achieve the purpose of quickly disconnecting the connecting head 400B from the docking head 100C. The disassembly is convenient and quick. At the same time as the first connecting rod 400 and the second connecting rod 100 are disconnected, the circuit docking piece 107 and the circuit connecting piece 401 are disconnected. It is convenient and quick to use.

[0069] In the present application, by providing the connector 400B, quick docking with the docking head 100C can be achieved to ensure a good connection effect. While the first connecting rod 400 and the second connecting rod 100 are connected, the electrical connection between the circuit docking member 107 and the circuit connecting member 401 can also be achieved simultaneously to connect the circuit. The structure is simple and the design is ingenious, and the mechanical connection and circuit connection between the first connecting rod 400 and the second connecting rod 100 can be achieved at the same time.

[0070] In a specific embodiment, see Figure 6 and Figure 8 The connector 400B also includes a limiting column 400B8, which is disposed in the accommodating cavity 400B6. The elastic member 400B2 is sleeved on the limiting column 400B8. The height of the limiting column 400B8 should not affect the pressing member 400B3 from completely accommodating the sliding groove. In order to prevent the elastic member 400B2 from escaping from the sliding groove due to elastic force during use, the limiting column 400B8 can be provided to limit the elastic member 400B2, thereby ensuring that the elastic member 400B2 can provide elastic force for the pressing member 400B3, so that the pressing member 400B3 extends out of the opening, and the pressing member 400B3 is clamped with the docking connector 100C. Here, the elastic member 400B2 can adopt a spring in the prior art.

[0071] In a specific embodiment, see Figure 6 and Figure 8 At least one side of the fixing member 400B1 is provided with a snap-in groove (not marked in the figure), and the accommodating cavity 400B6 is provided with a guide column 400B9 corresponding to the snap-in groove. When installing the fixing member 400B1, the side of the fixing member 400B1 provided with the snap-in groove is directed toward the guide column 400B9, and the fixing member 400B1 is pushed so that the snap-in groove can slide relative to the guide column 400B9 until the snap-in groove snaps into the guide column 400B9, and the fixing member 400B1 is installed in place and can achieve a stable connection effect.

[0072] In a specific embodiment, see Figure 4 , Figure 6-Figure 8, the connector 400B also includes a connecting portion 400B5 coaxially arranged with the docking portion 400B4, and the connecting portion 400B5 can be connected to the external first connecting rod 400. A screw (not shown in the figure) can be set at the connecting portion 400B5, and the connecting portion 400B5 is threadedly connected to the first connecting rod 400 by the screw, so as to realize the detachable connection between the connecting portion 400B5 and the first connecting rod 400, and the connection is reliable, and the installation or disassembly is convenient. Further, the screw can connect the connecting portion 400B5 and the first connecting rod 400 axially, and after fastening, the screw will remain in the first connecting rod 400, and the user cannot directly see the screw from the non-open end face, which can play the role of preventing violent disassembly and theft, and improve the stability of the overall device.

[0073] Second aspect

[0074] Based on the same inventive concept, see Figure 1-Figure 4 The present application also provides a connecting rod assembly, which can be used for a cleaning device with a mop. The connecting rod assembly includes a first connecting rod 400, a second connecting rod 100, a docking joint 100C and a connecting head 400B in the first aspect. The first connecting rod 400 and the connecting head 400B form a first connecting rod assembly 40, and the second connecting rod 100 and the docking joint 100C form a second connecting rod assembly 10. The first connecting rod 400 is connected to the connecting head 400B, and the second connecting rod 100 is connected to the docking joint 100C. The connecting head 400B can be connected to the docking joint 100C through an elastic clamping assembly, thereby realizing the connection between the first connecting rod 400 and the second connecting rod 100, and the connection is convenient.

[0075] In a specific embodiment, see Figure 1-Figure 4 , the outer diameter of the first connecting rod 400 is larger than the outer diameter of the connecting head 400B, and the outer diameter of the second connecting rod 100 is larger than the outer diameter of the butt joint 100C. When the first connecting rod 400 is connected to the connecting head 400B, the second connecting rod 100 is connected to the butt joint 100C, and the connecting head 400B is clamped with the butt joint 100C, the first connecting rod 400 and the second connecting rod 100 can be connected to form a Figure 1 The form shown in the figure realizes a concealed installation, that is, the first connecting rod 400 and the second connecting rod 100 are respectively mounted on the outside of the connecting head 400B and the docking head 100C, and no other connecting structure is arranged on the outer side walls of the first connecting rod 400 and the second connecting rod 100. The appearance is simple and beautiful. When the user uses the cleaning device including the connecting rod assembly for cleaning, the simple appearance can ensure that the cleaning device can be used normally under conditions of limited space.

[0076] In a specific embodiment, see Figure 7The docking head 100C is provided with an opening on one side facing the connector 400B, and the docking head 100C is sleeved on the connector 400B through the opening. The docking head 100C includes a circuit docking member 107 and at least one docking cavity 100C3. At least one docking cavity 100C3 corresponds to at least one connection cavity 400B7. The circuit docking member 107 is provided in the docking cavity 100C3 and can be electrically connected to the circuit connector 401. The docking head 100C is provided with a card slot (not shown in the figure), and the pressing member 400B3 can be snapped into the card slot, and the shape of the card slot is adapted to the shape of the pressing member 400B3.

[0077] When in use, when connecting the first connecting rod 400 and the second connecting rod 100, first, connect the first connecting rod 400 and the second connecting rod 100 to the connecting head 400B and the docking head 100C respectively (of course, this process can be completed when the connecting rod assembly is assembled for the first time); under the action of external force, the pressing piece 400B3 compresses the elastic piece 400B2, the elastic piece 400B2 is in a compressed state, and the pressing piece 400B3 is completely accommodated in the sliding groove; then the docking head 100C is put on the outside of the connecting head 400B, at this time, the external force is released, and in the state without external force, the pressing piece 400B3 gradually extends out of the opening of the sliding groove under the elastic force of the elastic piece 400B2, and is clamped in the clamping groove, so as to realize the clamping of the docking head 100C and the connecting head 400B, thereby realizing the connection between the first connecting rod 400 and the second connecting rod 100, and at the same time realizing the electrical connection between the circuit docking piece 107 and the circuit connecting piece 401. By providing a slot that matches the shape of the pressing piece 400B3 , the connection stability between the docking head 100C and the connecting head 400B can be improved, thereby ensuring the connection reliability between the first connecting rod 400 and the second connecting rod 100 .

[0078] In a specific embodiment, see Figure 3 and Figure 6 , the docking head 100C is provided with a first hole 100C2 corresponding to the card slot, and the first connecting rod 400 is provided with a second hole (not shown in the figure) corresponding to the first hole 100C2. When the first connecting rod 400 is connected to the connecting head 400B, and the connecting head 400B is in a state of being engaged with the docking head 100C, the first hole 100C2 and the second hole form a channel (not shown in the figure), so that the external force transmission mechanism extends into the channel to act on the pressing member 400B3. When it is necessary to separate the connecting head 400B from the docking head 100C, it is necessary to first use a tool (i.e., an external force transmission mechanism) to extend into the channel from the second hole corresponding to the first connecting rod 400, and press the pressing member 400B3. After the pressing member 400B3 exits the card 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.

[0079] In a specific embodiment, see Figure 1-Figure 4The connecting rod assembly also includes a grip assembly 50 and a hinge rod 20. The grip assembly 50 is connected to the first connecting rod 400. Specifically, the grip assembly 50 includes a clamping portion 50A, a gripping portion 50B and a display panel (not shown in the figure). The clamping portion 50A is connected to the first connecting rod 400, and the gripping portion 50B is convenient for the user to hold. The display panel can display the working parameters of the cleaning device connected to the connecting rod assembly. One end of the hinge rod 20 is connected to the second connecting rod 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 an articulated portion 20B. The connecting portion 20A is connected to the second connecting rod 100, and the articulated portion 20B is hinged to the mop head 30.

[0080] In a specific embodiment, see Figure 4 The first connecting rod 400 and the second connecting rod 100 are hollow inside, and the connecting rod assembly also includes a mounting bracket 100A, and the two ends of the mounting bracket 100A are respectively provided with a lower port 100A1 and an upper port 100A2, and the lower port 100A1 of the mounting bracket 100A faces the connecting portion 20A.

[0081] It should be noted that the specific installation position of the mounting bracket 100A is not limited here. The mounting bracket 100A can be installed in the first connecting rod 400, or the mounting bracket 100A can be installed in the second connecting rod 100. Of course, the mounting bracket 100A can also be arranged across the first connecting rod 400 and the second connecting rod 100, that is, a part of the mounting bracket 100A is arranged on the first connecting rod 400, and another part of the mounting bracket 100A is arranged on the second connecting rod 100. It should be further noted that the specific number of the mounting bracket 100A is not limited here, and the mounting bracket 100A can be set to at least 2, and at least one mounting bracket 100A can be respectively provided in the first connecting rod 400 and the second connecting rod 100.

[0082] Further, taking the installation bracket 100A disposed on the second connecting rod 100 as an example for explanation, the installation bracket 100A should be adapted to the hollow shape inside the second connecting rod 100, so that when the cleaning device is working, the installation bracket 100A placed inside the second connecting rod 100 will not have the problem of sliding and falling off; the installation bracket 100A disposed inside the second connecting rod 100 serves as a bearing and connection unit for the internal components of the connecting rod assembly, and can realize the integrated installation of the waterway channel, circuit line and power supply in the connecting rod assembly (which will be described in detail later). Since the second connecting rod 100 is hollow inside, the installation bracket 100A placed inside the second connecting rod 100 supports the inner wall of the second connecting rod 100 to increase the structural strength and rigidity of the second connecting rod 100, thereby further increasing the rigidity of the connecting rod assembly while reducing the overall weight of the connecting rod assembly.

[0083] In a specific embodiment, see Figure 4 , Fig. 9 and Fig.10 The connecting rod assembly further includes a water pump 101 disposed on the mounting bracket 100A, and a water inlet pipe (not shown in the figure) and a water outlet pipe (not shown in the figure) disposed on the hinge rod 20. The water pump 101 is disposed near the lower port 100A1 of the mounting bracket 100A, and is provided with a water outlet 101a and a water inlet 101b, both of which are disposed toward the hinge rod 20, and the pipelines of the water outlet 101a and the water inlet 101b pass through the lower port 100A1 and are communicated with the water outlet pipe and the water inlet pipe respectively, and the water inlet pipe and the water outlet pipe are communicated with the tractor 30, thereby forming a waterway channel connecting the connecting rod assembly and the tractor 30.

[0084] In the present application, a water pump 101 is arranged on the mounting bracket 100A, and the water outlet 101a and the water inlet 101b of the water pump 101 are both arranged toward the direction of the hinge rod 20, so that the water pump 101 and the connecting part 20A form a connected water channel, which can minimize the length of the water channel inside the connecting rod assembly and make the connection more convenient. At the same time, a single docking of the second connecting rod 100 and the hinge rod 20 can achieve quick docking of the water channel.

[0085] In a specific embodiment, see Figure 4 , Fig. 9 and Fig.10 The connecting rod assembly also includes a power supply 120 and a control panel 110 provided on the mounting bracket 100A. The power supply 120 is provided near the upper port 100A2 of the mounting bracket 100A, and the power supply 120 may include more than two batteries connected in series and then in parallel. The control panel 110 may be threadedly connected to the mounting bracket 100A through a fixing nut column (not shown in the figure), and the control panel 110 is electrically connected to the water pump 101 and the drive motor (not shown in the figure) in the tractor 30, and the drive motor is used to drive the cleaning roller (not shown in the figure) of the tractor 30 to rotate, and the control panel 110 is electrically connected to the power supply 120. During the process of the control panel 110 controlling the water pump 101 and the drive motor to work, the power supply 120 is in a state of discharging outward. An electrode sheet group (not shown in the figure) is provided on the control panel 110, and the electrode sheet group clamps the power supply 120. The mounting bracket 100A and the control panel 110 may jointly fix the power supply 120 to improve the integration of the mounting bracket 100A.

[0086] Furthermore, the holding 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.

[0087] In the present application, after the grip assembly 50, the first connecting rod 400, the second connecting rod 100, and the hinge rod 20 are connected and fixed in sequence, the power supply 120 and the control panel 110 are integrated and installed inside the connecting rod assembly, reducing the overall volume of the device to improve the protection and convenience of installation and disassembly. At the same time, the second connecting rod 100 and the hinge rod 20 can achieve a quick connection between the circuit lines, and the first connecting rod 400 and the grip assembly 50 can achieve a quick connection between the circuit lines.

[0088] In a specific embodiment, see 3 and Figure 4 The control panel 110 is electrically connected to the first wire 105, and the end of the first wire 105 is provided with a first wire connector 104, and the first wire connector 104 passes through the lower port 100A1 and is electrically connected to the connecting portion 20A of the hinge rod 20. The control panel 110 is also electrically connected to the second wire 106, and the second wire 106 is electrically connected to the grip assembly 50.

[0089] In this way, a control panel 110 is set on the mounting bracket 100A, and 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, and the second wire 106 is electrically connected to the holding assembly 50. The hinge rod 20, the first connecting rod 400, the second connecting rod 100 and the holding assembly 50 can be quickly connected to each other, and the circuit lines can be quickly connected. The components of the connecting rod assembly (the hinge rod 20, the second connecting rod 100, the first connecting rod 400 and the holding assembly 50) can be quickly connected by a single connection to realize the connected circuit lines inside each component.

[0090] In a specific embodiment, see 3. Figure 4 , Fig. 9 and Fig.10 , a flow sensor 103 is also provided on the mounting bracket 100A, and the flow sensor 103 is arranged between the water pump 101 and the lower port 100A1, and the flow sensor 103 is connected to the water outlet 101a to measure the flow in the water outlet 101a. The flow sensor 103 is also electrically connected to the control panel 110, and the flow sensor 103 transmits the real-time measured flow data of the water outlet 101a back to the control panel 110, and the control panel 110 can adjust the water volume control strategy of the water pump 101 in real time according to the received flow data, so as to make the floor scrubber more energy-saving and efficient.

[0091] In a specific embodiment, see Figure 4At least one temperature sensor 111 is also provided on the mounting bracket 100A. The temperature sensor 111 is used to sense the temperature of the water pump 101 and the power supply 120, and to provide feedback to the display panel provided in the holding component 50 through a signal connection. The display panel can obtain the temperature of the water pump 101 and the power supply 120 in real time, and the control panel 110 can adjust the control strategy of the water pump 101 and the driving motor in time, so as to make the floor scrubber more energy-efficient and efficient.

[0092] In a specific embodiment, see Figure 3 and Figure 4 The second connecting rod assembly 10 also includes a connecting sleeve 100B provided on the second connecting rod 100. The connecting sleeve 100B is hollow inside, and a clamping seat 100B1 is provided at the upper end of the connecting sleeve 100B. The end of the connecting portion 20A of the hinge rod 20 is provided with a clamping docking portion, a water inlet interface and a water outlet interface (not shown in the figure). The water inlet interface is connected to the water inlet pipe, and the water outlet interface is connected to the water outlet pipe. When the mounting bracket 100A is arranged in the second connecting rod 100 and the connecting sleeve 100B is sleeved on the connecting portion 20A of the hinge rod 20, the end of the connecting portion 20A extends into the connecting sleeve 100B, the water inlet interface and the water outlet interface are respectively connected to the pipelines of the water inlet 101b and the water outlet 101a, and the clamping docking portion is clamped with the clamping seat 100B1.

[0093] Furthermore, a fastening screw (not shown in the figure) is provided on the connecting sleeve 100B, through which the connecting sleeve 100B and the second rod body 100 are threadedly connected, thereby realizing a detachable connection between the connecting sleeve 100B and the second rod body 100, which is reliable and easy to install or remove. The fastening screw can connect the second rod body 100 and the connecting sleeve 100B axially, and after fastening, the fastening screw will remain in the second rod body 100, and the user cannot directly see the fastening screw from the non-open end face, which can play the role of preventing violent disassembly and theft, and improve the stability of the entire connecting rod assembly and even the cleaning device.

[0094] The connecting sleeve 100B realizes the detachable connection between the second connecting rod 100 and the hinge rod 20, making the connection between the hinge rod 20 and the second connecting rod 100 more stable and improving the stability of the structure. At the same time, the mechanical connection, electrical connection and water connection of the second connecting rod 100 and the hinge rod 20 can be completed by a single quick connection between the second connecting rod 100 and the hinge rod 20, which is efficient and convenient.

[0095] In this application, see Figures 1 to 5The first connecting rod 400 and the second connecting rod 100 are detachably connected between the hinge rod 20 and the grip assembly 50, and the water pump 101, the control panel 110 and the power supply 120 are integrated and installed by providing a mounting bracket 100A. The water pump 101 is controlled by the grip assembly 50 to supply water to the tractor 30, and the power supply 120 is controlled to supply power to the water pump 101 and the drive motor to perform cleaning work.

[0096] When the grip assembly 50, the first connecting rod 400, the second connecting rod 100 and the hinge rod 20 are connected in sequence, the water channel of the water pump 101, the hinge rod 20 and the tractor 30 can be connected synchronously, and the circuit lines of the tractor 30, the hinge rod 20, the second connecting rod 100, the first connecting rod 400 and the grip assembly 50 can be connected synchronously. The present application can realize that the grip assembly 50, the first connecting rod 400, the second connecting rod 100 and the hinge rod 20 are connected and fixed to each other, and the power supply 120, the control panel 110, the water channel and the circuit line are integrated and installed inside the entire connecting rod assembly, reducing the overall volume of the equipment and improving the protection and convenience of installation and disassembly.

[0097] The following is divided into different embodiments according to the specific installation position of the installation bracket 100A, and the differences in the installation positions of the components related to the installation bracket 100A in different embodiments are described in detail.

[0098] Embodiment 1

[0099] See also Figure 3 and Figure 4 The second connecting rod 100 is provided with an inner cavity, the mounting bracket 100A is provided in the inner cavity of the second connecting rod 100, and a connecting sleeve 100B is provided at the lower end of the second connecting rod 100. The lower port 100A1 of the mounting bracket 100A is connected to the connecting sleeve 100B. Specifically, a clamping seat 100B1 is provided at the upper end of the connecting sleeve 100B, and the clamping seat 100B1 is adapted to the lower port 100A1 of the mounting bracket 100A, and the clamping seat 100B1 can be adapted to connect with the lower port 100A1 of the mounting bracket 100A.

[0100] See also Figure 4-Figure 6The docking portion 400B4 of the connector 400B is provided with only one connection cavity 400B7, in which the circuit connector 401 is accommodated. In order to form a complete circuit line, a third wire 402 is provided in the first connecting rod 400 for electrically connecting the circuit connector 401 and the grip assembly 50. The control panel 110 installed on the mounting bracket 100A is electrically connected to the first wire 105 and the second wire 106 respectively. The end of the first wire 105 is provided with a first wire connector 104, which passes through the lower port 100A1 and can be electrically connected to the connecting portion 20A of the hinge rod 20; the second wire 106 passes through the upper port 100A2 and is electrically connected to the circuit docking member 107. When the holding assembly 50, the first connecting rod 400, the second connecting rod 100 and the hinge rod 20 are connected in sequence, the first wire connector 104 is electrically connected to the connecting portion 20A of the hinge rod 20; the circuit connector 107 is electrically connected to the circuit connector 401, so that the second wire 106 connector is electrically connected to the circuit connector 107, the circuit connector 401, the third wire 402 in sequence, and is electrically connected to the holding assembly 50.

[0101] In this embodiment, see Figure 1 , Figure 2 and Figure 4 The pipelines of the water outlet 101a and the water inlet 101b of the water pump 101 pass through the lower port 100A1 and are connected to the water inlet pipe and the water outlet pipe respectively, and the water inlet pipe and the water outlet pipe are connected to the tractor 30, thereby forming a waterway channel connecting the connecting rod assembly and the tractor 30.

[0102] See also Figure 4 , Figure 6 and Figure 7 In order to achieve stable installation of the mounting bracket 100A, a joint portion 100C1 is provided on a side of the docking head 100C facing the mounting bracket 100A, and the joint portion 100C1 can be adapted to be connected with the upper port 100A2 of the mounting bracket 100A.

[0103] In this embodiment, see Figure 4 Since the mounting bracket 100A is mounted in the inner cavity of the second connecting rod 100, the inner cavity of the first connecting rod 400 is not equipped with other components except the third wire 402. The weight of the second connecting rod 100 exceeds the weight of the first connecting rod 400, so that the overall center of gravity of the connecting rod assembly is biased downward, and the user will feel lighter when pushing and pulling the tractor 30 by holding the grip assembly 50.

[0104] In this embodiment, the mechanical docking of the second connecting rod 100 and the hinge rod 20 simultaneously realizes the synchronous docking of the circuit line and the water channel between the two, while the mechanical docking of the second connecting rod 100 and the first connecting rod 400, and the mechanical docking of the first connecting rod 400 and the gripping assembly 50 only realizes the corresponding synchronous docking of the circuit line between the two. In order to match the differences in the corresponding docking interfaces at the two mechanical docking locations, each docking interface itself has been foolproofed, so there will be no docking errors between the hinge rod 20, the second connecting rod 100, the first connecting rod 400, and the gripping assembly 50, thereby avoiding the problem of incorrect installation between the components and improving the installation efficiency of the equipment.

[0105] Embodiment 2

[0106] Compared with the aforementioned embodiment 1, in this embodiment, the mounting bracket 100A is arranged in the inner cavity of the first connecting rod 400. The connector 400B and the docking joint 100C need to be adjusted, which is slightly different from the embodiment 1. The docking portion 400B4 of the connector 400B is provided with two independent connecting cavities 400B7, one of which is used to accommodate the circuit connector 401, and the other is used to accommodate the pipes of the water outlet 101a and the water inlet 101b of the water pump 101. The two independent connecting cavities 400B7 can ensure the separation of water and electricity, and have high safety. Correspondingly, the docking joint 100C is provided with two independent docking cavities 100C3, one of which is provided in correspondence with the connecting cavity 400B7 accommodating the circuit connector 401, and is used to accommodate the circuit docking member 107, and the other is provided for the pipes of the water outlet 101a and the water inlet 101b of the water pump 101 to pass through.

[0107] The circuit line and water channel of this embodiment are also slightly different from those of the above-mentioned embodiment 1. The control panel 110 is electrically connected to the first wire connector 104 through the first wire 105. The first wire connector 104 passes through the lower port 100A1 and the inner cavity of the second connecting rod 100 in turn, and is electrically connected to the connecting portion 20A of the hinge rod 20; the control panel 110 is directly electrically connected to the grip assembly 50 through the second wire 106. The pipelines of the water outlet 101a and the water inlet 101b of the water pump 101 pass through the lower port 100A1 and the inner cavity of the second connecting rod 100 in turn, and are connected to the water inlet pipe and the water outlet pipe respectively. The electrical connection harness and water connection pipeline provided at the lower end of the mounting bracket 100A need to pass through the entire cavity of the second connecting rod 100, and accordingly, the circuit harness and water pipeline connected from the hinge rod 20 to the circuit harness and water pipeline will be correspondingly longer. Other technical details are exactly the same as those of embodiment 1, and will not be repeated here.

[0108] In this embodiment, the center of gravity of the connecting rod assembly is higher than that of the first embodiment, and when the user holds the grip assembly 50 to push and pull the tractor 30, the user's experience is somewhat different from that of the first embodiment. In both the first and second embodiments, the power supply 120, the circuit line, the water channel and the control panel 110 are integrated and installed inside the connecting rod assembly, making full use of the internal volume of the connecting rod assembly. Compared with the method of arranging these components outside the connecting rod assembly, the external structure of the connecting rod assembly can be more simple, which can ensure that the connecting rod assembly can be used normally with the cleaning device under space-constrained use conditions, and improve the protection and convenience of installation and disassembly.

[0109] Embodiment 3

[0110] Compared with the aforementioned embodiments one and two, in the scheme of this embodiment, the mounting bracket 100A is arranged between the first connecting rod 400 and the second connecting rod 100; since the length of the mounting bracket 100A is longer, relative to embodiments one and two, the length dimension of the mounting bracket 100A cooperating with the first connecting rod 400 and the second connecting rod 100 will be longer, and the first connecting rod 400 and the second connecting rod 100 through the mounting bracket 100A will be more stable. Other technical details are completely consistent with the aforementioned embodiments one and two, and will not be repeated here.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some structures (technical features) in one or more embodiments may be replaced or combined by equivalent means, and these modifications or replacements or combinations do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model, unless the embodiments explicitly exclude the possibility of replacing or combining structures (technical features) in different embodiments, or this replacement or combination is contrary to the overall concept of the utility model.
