Description

[0001] This application is a divisional application of Chinese patent application number 202420856981.9, application date April 23, 2024, and invention name “A connecting rod and a floor scrubber”, the contents of which are incorporated herein by reference. Technical Field

[0002] The utility model relates to the technical field of cleaning equipment, in particular to a connecting rod and a floor scrubber. Background Art

[0003] In the early days, people used brooms, mops, floor wipes, etc. to clean the floor. These tools mainly rely on manual operation to complete the cleaning work. With the advancement of science and technology, people's requirements for floor cleaning tools have gradually increased. The first to appear was the vacuum cleaner, which relies on electricity to generate negative pressure to absorb garbage, dust, etc. on the ground. According to the cleaning methods and the circulation channels of small and large particles of garbage, this type of technology is usually classified as air-dust circulation technology. However, due to the limitations of its working principle, the vacuum cleaner cannot clean some garbage and stains that are firmly attached to the ground. Therefore, a new "water-dust circulation" floor scrubber has appeared. The motor drives the cleaning cylinder to wipe the ground. At the same time, the floor cleaner will also be equipped with a water supply system and a sink to clean the cleaning cylinder, thereby perfectly cleaning the ground.

[0004] The prior art CN220175029U discloses a connecting rod for a floor scrubber, comprising a hollow rod body, an upper connecting assembly and a lower connecting assembly, and also comprising an upper connecting shell and a lower connecting shell, wherein the upper end of the upper connecting shell is fixedly connected to the handle of the floor scrubber, and the lower end of the lower connecting shell is fixedly connected to the mop head of the floor scrubber, and the upper and lower side walls of the rod body are provided with limiting grooves, and when the upper and lower ends of the rod body are respectively inserted into the upper connecting shell and the lower connecting shell, the upper connecting shell and the lower connecting shell are respectively extended into the upper docking port of the rod body, and the upper connecting assembly, the upper connecting shell, the lower connecting assembly and the lower connecting shell cooperate with each other accordingly, so that the upper and lower ends of the rod body are respectively firmly connected to the handle and the mop head of the floor scrubber.

[0005] However, the existing "water-dust circulation" floor washer connection rod, whether it is set at the bottom of the water tank or on the body, inevitably occupies a large volume. At the same time, in order to power the floor washer connection rod, it is necessary to pull the floor washer connection rod away to the adapter module for easy power supply. When the user takes the water tank or performs maintenance on the floor washer body, it is inevitable that water will drip onto the adapter module used to power the floor washer connection rod.

Unless otherwise clearly defined in the specification, when other understandings cannot achieve the corresponding functions or effects, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0061] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model. The present utility model will be further described below with specific embodiments, but it is not regarded as a limitation of the present utility model.

[0062] In the first aspect, as Figure 1-13 shown, a connecting rod of the present utility model is used for a floor washer with a tow head. One end of it is hinged to the tow head 30. The connecting rod includes a hinge member 20, a rod body group, a handle 50, a lower kit and an upper kit; one end of the hinge member 20 is hinged to the tow head 30; both ends of the rod body group are open, and the lower open end of the rod body group is detachably connected to the other end of the hinge member 20; the rod body group is detachably connected between the hinge member 20 and the handle 50. A water pump 101 is provided inside the rod body group. The rod body group includes a lower rod 10 and an upper rod 40 that are butted against each other; the handle 50 is detachably connected to the upper open end of the rod body group; the lower kit is detachably connected between the lower rod 10 and the hinge member 20; the upper kit is detachably connected between the lower rod 10 and the upper rod 40; the hinge member 20, the rod body group and the handle 50 can be quickly docked in sequence; the hinge member 20 and the rod body group can complete the mechanical docking, circuit line docking and water pipeline docking between the two synchronously at one time; the rod body group and the handle 50 can complete the mechanical docking and circuit line docking between the two synchronously at one time. The hinge member 20 realizes the quick docking with the rod body group through the lower kit; the lower rod 10 realizes the quick docking with the upper rod 40 through the upper kit; the mechanical docking between the hinge member 20 and the rod body group can also complete the double docking of the circuit lines and water pipelines built in the two at the same time; the mechanical docking between the rod body group and the handle 50 can also complete the circuit line docking built in the two at the same time.

[0063] Thus, the utility model reduces the overall volume of the floor washing machine equipment by connecting and fixing the hinge piece, the rod body group and the handle, and integrally installing the power supply, the circuit, the water circuit and the control board inside the rod body group, so as to improve the protection performance and the convenience of installation and disassembly. At the same time, the connection channels between the rod body group and the hinge piece accommodate the circuit lines and the water circuit channels connecting the water pump and the hinge piece. Different from the connection between the rod body group and the hinge piece, only the circuit channel connecting the water pump and the handle is accommodated in the connection channel between the rod body and the handle. During installation, the user can correctly adapt and install the hinge piece, the rod body group and the handle by distinguishing whether the rod body group is the end with double connections of the water circuit and the circuit to the hinge piece or the end where the rod body is only connected to the circuit of the handle, thus avoiding the problem of incorrect installation between each component and improving the installation efficiency of the equipment.

[0064] In one or some alternative embodiments, as Figure 3 、 Figure 4 shown, the hinge piece 20 includes a connection head 20A and a hinge head 20B, and the hinge head 20B is hinged to the drag head 30. The handle 50 is away from the drag head 30 and has a clamping portion 50A and a holding portion 50B.

[0065] In one or some alternative embodiments, as Figures 3 to 5 、 Figure 7 、 Figure 9 、 Figure 11 shown, the lower kit includes a lower rod lower docking sleeve 100B, which is detachably connected to the lower end of the lower rod 10 and can be quickly docked with the hinge piece 20.

[0066] In one or some alternative embodiments, as Figures 3 to 5 、 Figure 7 、 Figure 8 、 Figure 10 shown, the upper kit includes a lower rod upper docking sleeve 100C and an upper rod lower docking sleeve 400B that can be quickly docked with each other. The lower rod upper docking sleeve 100C is detachably connected to the lower end of the lower rod 10, and the upper rod lower docking sleeve 400B is detachably connected to the lower end of the upper rod 40.

[0067] In one or some alternative embodiments, as Figure 3 、 Figure 4As shown, the rod body group includes a lower rod 10 and an upper rod 40 that are butt - jointed with each other; when the lower rod 10 and the upper rod 40 are butt - jointed, at least the circuit lines built - in the lower rod 10 and the upper rod 40 are synchronously butt - jointed; the interiors of the lower rod 10 and the upper rod 40 are hollow, and the rod body group further includes a rod holder 100A. Both ends of the rod holder 100A are open and it is arranged inside the lower rod 10 or the upper rod 40; one end of the rod holder 100A is provided with a docking port 100A1, and the docking port 100A1 faces the connection head 20A of the hinge member 20; the other end of the rod holder 100A is provided with a lead - out port 100A2, and the lead - out port 100A2 faces the handle 50 and is conductively connected thereto.

[0068] It should be noted that there is no limitation here as to whether the rod holder 100A is installed inside the lower rod 10 or the upper rod 40. Of course, the rod holder 100A can also be installed between the lower rod 10 and the upper rod 40. As long as the technical solution of installing the rod holder 100A inside the rod body is within the protection scope of this application. More importantly, there is no limitation here as to the specific number of the rod holders 100A. The rod holder 100A can be set to at least 2. At least one of the rod holders 100A can be respectively arranged inside the lower rod 10 and the upper rod 40. The technical solutions of installing at least 2 rod holders 100A inside the rod body are all within the protection scope of this application.

[0069] In this way, the shape of the rod holder is adapted to the hollow shape inside the lower rod or the upper rod, so that when the floor washer is working, the rod holder placed inside the lower rod or the upper rod will not have problems of sliding and falling off; the rod holder arranged inside the lower rod or the upper rod serves as a bearing and connecting unit for the components inside the rod body to realize the integrated installation of the water circuit, circuit and power supply inside the rod body; on the other hand, because the interiors of the lower rod and the upper rod are hollow, the support of the rod holder placed inside the lower rod and / or the upper rod on the inner walls of the lower rod and the upper rod can also increase the structural strength and rigidity of the lower rod and / or the upper rod, and further increase the rigidity of the rod body while reducing the overall weight of the rod body.

[0070] In one or some alternative embodiments, as Figures 3 to 5 、 Figure 7 shown, a water pump 101 is provided on the rod holder 100A. The water pump 101 is arranged on the side of the rod holder 100A close to the docking port 100A1; the water pump 101 is provided with a water outlet 101a and a water inlet 101b. Both the water outlet 101a and the water inlet 101b are arranged in the direction of the hinge member 20. The water outlet 101a and the water inlet 101b are respectively connected with a water outlet pipe and a water inlet pipe. The water outlet pipe and the water inlet pipe respectively pass through the rod body group and are communicated with the connection head 20A of the hinge member 20 to form a water - circuit channel connecting the rod body and the hinge member 20.

[0071] Thus, a water pump is provided on the rod holder, and the water outlet and water inlet of the water pump are both arranged towards the direction of the hinge member, which can conveniently pass the water outlet pipe and water inlet pipe connecting the water outlet, water inlet and hinge member through the rod body respectively and communicate with the connecting head of the hinge member, enabling the shortest length of the water pipeline inside the rod body and more convenient connection. At the same time, a single docking of the rod body and the hinge member can achieve a quick docking of the water channel communicating the rod body and the hinge member.

[0072] In one or some alternative embodiments, as Figures 3 to 5 shown, a battery pack 120 and a control board 110 are further provided on the rod holder 100A. The battery pack 120 is arranged on one side of the rod holder 100A close to the lead port 100A2; the control board 110 is threadedly connected to a fixed nut column (not shown in the drawing) of the rod holder 100A. An electrode plate group (not shown in the drawing) is provided on the control board 110, and the electrode plate group clamps the battery pack 120. The rod holder 100A and the control board 110 jointly fix the battery pack 120 to improve the integration degree of the rod holder 100A; in a preferred embodiment, the battery 120 is placed as a power source inside the rod body. By providing the rod holder 100A, while the rod body is convenient for disassembly and installation, it is also convenient for the replacement and maintenance of the battery 120.

[0073] Furthermore, the battery pack 120 includes more than 2 batteries connected in series first and then in parallel. The control board 110 is electrically connected to the water pump 101 and a drive motor (not shown in the drawing) that drives the cleaning roller to rotate in the towing head. The control board 110 is electrically connected to the charging port (not shown in the drawing) of the handle 50. When the control board 110 controls the water pump 101 and the drive motor to work, the battery pack 120 is in a working condition of discharging outward. When an external power adapter is electrically connected to the charging port, the external power adapter charges the battery pack 120 through the control board 110.

[0074] Thus, a battery pack and a control board are provided on the rod holder. Inside the rod body, the control board is electrically connected to the water pump and a drive motor that drives the cleaning roller to rotate in the towing head. An electrode plate group that clamps the battery pack is provided on the control board, which can conveniently connect and fix the hinge member, the rod body and the handle to integrate and install the power supply, circuit and control board inside the rod body, reducing the overall volume of the device and improving the protection and the convenience of installation and disassembly; at the same time, a single docking of the rod body and the hinge member can achieve a quick docking of the circuit line communicating the rod body and the hinge member, and a single docking of the rod body and the handle can achieve a quick docking of the circuit line communicating the rod body and the handle.

[0075] In one or some alternative embodiments, as Figures 3 to 5As shown, the control board 110 is electrically connected to the lower terminal harness 105. The end of the lower terminal harness 105 is provided with a lower docking terminal 104. After the lower docking terminal 104 passes through the docking port 100A1 and the rod body in sequence, it is electrically connected to the connection head 20A of the hinge member 20.

[0076] In one or some alternative embodiments, as Figures 3 to 5 shown, the control board 110 is also electrically connected to the upper terminal harness 106. The end of the upper terminal harness 106 is provided with an upper docking terminal 107. After the upper docking terminal 107 passes through the lead port 100A2 and the rod body in sequence, it is electrically connected to the handle 50.

[0077] In this way, a control board is provided on the rod holder. Within the rod body group, the control board is electrically connected outside the rod body group. The control board is electrically connected to the lower terminal harness. The lower terminal harness passes through the docking port and is electrically connected to the hinge member. The control board is electrically connected to the upper terminal harness. The upper terminal harness passes through the lead port and is electrically connected to the handle. This can facilitate the quick docking of the hinge member, the rod body group, and the handle with each other. At the same time, a single docking of the rod body group and the hinge member can achieve the quick docking of the circuit line connecting the rod body group and the hinge member, and a single docking of the rod body group and the handle can achieve the quick docking of the circuit line connecting the rod body group and the handle.

[0078] In one or some alternative embodiments, as Figures 3 to 5 shown, a flow sensor 103 is further provided on the rod holder 100A. The flow sensor 103 is arranged between the water pump 101 and the docking port 100A1. The flow sensor 103 communicates with the water outlet 101a and the water outlet pipe to measure the flow rate in the water outlet 101a. Further, the flow sensor 103 is also electrically connected to the control board 110. The flow sensor 103 transmits the real-time flow rate data of the water outlet 101a of the water pump 101 back to the control board 110. The control board 110 can adjust the control strategy for the water pump 101 in real time according to the received flow rate data.

[0079] In this way, after a flow sensor is provided in the rod body, the control board can adjust the control strategy for the water pump in real time according to the flow rate data of the water pump, so as to make the floor washer work more energy-efficiently and efficiently.

[0080] In one or some alternative embodiments, as Figures 3 to 5As shown, the control board 110 is further provided with at least one temperature sensor 111. The temperature sensor 111 senses the temperatures of the control board 110 and the battery pack 20, and feeds back through signal connection to a display unit (not shown in the drawings) provided on the surface of the handle 50.

[0081] In this way, when the control board is further provided with at least one temperature sensor, after the control board can obtain the temperatures of the battery pack and the control board in real time, the control board can timely adjust the control strategies for the water pump and the drive motor based on the temperature data measured in real time, so that the floor washer can work more energy-efficiently and efficiently.

[0082] In one or some alternative embodiments, as Figures 3 to 5 shown, the lower rod 10 includes a lower rod housing 100; the lower rod housing 100 is hollow and has an upper open end and a lower open end; the upper docking sleeve 100C on the lower rod is detachably connected to the upper open end of the lower rod housing 100 and can be quickly docked with the upper rod 40; the lower docking sleeve 100B on the lower rod is detachably connected to the lower open end of the lower rod housing 100 and can be quickly docked with the hinge member 20.

[0083] In one or some alternative embodiments, as Figures 3 to 5 、 Figures 7 to 11 shown, the upper rod 40 includes an upper rod housing 400; the upper rod housing 400 is hollow and both ends of the upper rod housing 400 are open. The upper open end of the upper rod housing 400 is connected to the clamping portion 50A of the handle 50; the lower docking sleeve 400B on the upper rod is detachably connected to the lower open end of the upper rod housing 400 and can be quickly docked with the lower rod 10. The lower docking sleeve 400B on the upper rod and the lower rod 10 can be quickly docked at the upper docking sleeve 100C on the lower rod, and this docking can simultaneously achieve the mechanical docking and the electrical connection docking of the lower rod 10 and the upper rod 40.

[0084] In one or some alternative embodiments, as Figure 4 、 Figure 5 、 Figure 7 、 Figure 9 、 Figure 11 shown, the hinge member 20 includes a connection head 20A and a hinge head 20B. A connection end (not shown in the drawings) is provided at the end of the connection head 20A of the hinge member 20. Connection terminals, a water inlet interface and a water outlet interface are provided inside the connection end. The lower docking sleeve 100B on the lower rod is sleeved on the connection head 20A of the hinge member 20. The connection end of the connection head 20A extends into the lower rod terminal seat 100B1 of the lower docking sleeve 100B, and the lower rod terminal seat 100B1 is adaptively fixed to the docking port 100A1 of the rod frame 100A.

[0085] In this way, the rod body group and the hinge member 20 are detachably connected to each other through the lower rod lower docking sleeve 100B, making the connection between the hinge member 20 and the rod body more stable and improving the structural stability. At the same time, through the single quick docking of the rod body group and the hinge member 20, the mechanical docking, electrical connection docking, and waterway connection docking between the rod body group and the hinge member 20 can be completed, which is efficient and convenient.

[0086] In one or some alternative embodiments, as Figures 1 to 3 shown, the connecting rod is also hinged with a tow head 30 at the hinge head 20B of the hinge member 20. The water pump 101 in the rod body group is controlled by the handle 50 to supply water to the tow head 30, and the battery pack 120 in the rod body group is controlled by the handle 50 to supply power to the water pump 101 and the drive motor, so as to carry out cleaning work.

[0087] In this application, the mechanical docking of the rod body group and the hinge member 20 can simultaneously realize the simultaneous docking of the circuit line and the waterway channel between the rod body group and the hinge member 20; different from the mechanical docking of the rod body group and the handle 50, only the simultaneous docking of the circuit line between the rod body group and the handle 50 can be realized. Coupled with the differences in the corresponding docking interfaces at the two mechanical docking locations, the anti-fooling treatment has been done to each docking interface, so the user will not make mistakes in docking the hinge member 20, the rod body group, and the handle 50, thus avoiding the problem of incorrect installation between components and improving the installation efficiency of the device. Moreover, when an electrical connection failure occurs, if the control board 110 reports a connection failure of the water pump 101 or the drive motor, then the failure may only occur in the electrical connection failure of the circuit line between the rod body group and the hinge member 20. If there is a display failure of the display device of the handle 50, the electrical connection failure can only occur in the electrical connection failure of the circuit line between the rod body group and the handle 50. If the control board 110 reports a low flow rate of the water pump 101, in addition to the possible failure of the water pump 101 itself, the connection of the waterway channel between the rod body group and the hinge member 20 may also leak.

[0088] The following will separately describe in detail the more detailed technical solutions of this application in several embodiments according to the specific installation position and installation method of the rod frame 100A in the rod body group. Embodiment

[0089] Specifically, as Figure 3 、 Figure 4As shown, the rod holder 100A is disposed within the lower rod 10; there will be no problem of the rod holder 100A sliding and falling off within the lower rod 10; the rod holder 100A disposed inside the lower rod 10 serves as a bearing and connecting unit for the components inside the lower rod 10 to achieve the integrated installation of the water circuit, circuit, and power supply within the lower rod 10; the support of the rod holder 100A on the inner wall of the lower rod 10 can also increase the structural strength and rigidity of the lower rod 10.

[0090] Specifically, as Figures 3 to 5 、 Figures 7 to 11 shown, a lower rod upper docking sleeve 100C is connected to the upper opening end of the lower rod housing 100, and a lower rod lower docking sleeve 100B is connected to the lower opening end of the lower rod housing 100. Between the lower rod lower docking sleeve 100B and the lower rod upper docking sleeve 100C, a rod holder 100A is further disposed within the lower rod housing 100. The rod holder 100A has openings at both ends. One end of the rod holder 100A is provided with a docking port 100A1, and the docking port 100A1 is connected to the lower rod lower docking sleeve 100B; the other end of the rod holder 100A is provided with a lead port 100A2, and the lead port 100A2 is electrically connected to the handle 50 through a wire. Further, one side of the lower rod lower docking sleeve 100B is provided with an opening, and the other side is provided with a lower rod lower terminal seat 100B1; the lower rod lower docking sleeve 100B is sleeved on the connection head 20A of the hinge member 20 through the opening, and is adaptively connected to the docking port 100A1 of the rod holder 100A through the lower rod lower terminal seat 100B1. The lower rod lower terminal seat 100B1 is electrically connected to the terminal seat (not marked in the drawing) within the connection head 20A, so that the rod holder 100A and the hinge member 20 are fixedly connected. Further, one side of the lower rod upper docking sleeve 100C is provided with an opening, and the other side is provided with a lower rod upper terminal seat 100C1; the upper rod 40 includes an upper rod housing 400 and an upper rod lower docking sleeve 400B that are detachably connected to each other. One side of the upper rod lower docking sleeve 400B is provided with an opening, and the other side is provided with a lower docking terminal 104; the upper rod lower docking sleeve 400B is sleeved on the lower rod upper docking sleeve 100C through the opening. The lower rod upper terminal seat 100C1 is adaptively connected to the lead port 100A2 of the rod holder 100A, and the lower rod upper terminal seat 100C1 is electrically connected to the upper rod lower docking terminal 404 of the upper rod lower docking sleeve 400B, so that the lower rod 10 and the upper rod 40 are fixedly connected.

[0091] Further, as Figures 3 to 5As shown, a water pump 101 is provided on the rod frame 100A, and the water pump 101 is arranged on one side of the rod frame 100A close to the docking port 100A1; the water pump 101 is provided with a water outlet 101a and a water inlet 101b, and a water outlet pipe and a water inlet pipe are respectively arranged at the water outlet 101a and the water inlet 101b. The water outlet pipe and the water inlet pipe respectively pass through the lower rod lower docking sleeve 100B and communicate with the connector 20A of the hinge member 20 to form a water channel for connecting the lower rod 10 and the hinge member 20.

[0092] Further, as Figures 3 to 5 shown, a battery pack 120 and a control board 110 are further arranged on the rod frame 100A. The battery pack 120 is arranged on one side of the rod frame 100A close to the lead port 100A2; the control board 110 is threadedly connected to the fixed nut column of the rod frame 100A. The control board 110 is provided with an electrode plate group, and the electrode plate group clamps the battery pack 120. The rod frame 100A and the control board 110 jointly fix the battery pack 120.

[0093] Further, as Figures 3 to 5 、 Figures 7 to 11 shown, the control board 110 is electrically connected to the lower terminal wire harness 105. The end of the lower terminal wire harness 105 is provided with a lower docking terminal 104. The lower docking terminal 104 sequentially passes through the docking port 100A1 and the lower rod lower docking sleeve 100B, and after passing through the lower rod 10, it is electrically connected to the connector 20A of the hinge member 20.

[0094] Further, as Figures 3 to 5 shown, the control board 110 is also electrically connected to the upper terminal wire harness 106. The end of the upper terminal wire harness 106 is provided with an upper docking terminal 107. The other end of the upper terminal wire harness 106 is connected and sequentially passes through the lead port 100A2 and the lower rod upper docking sleeve 100C, and after passing through the lower rod 10, it is electrically connected to the handle 50.

[0095] Further, as Figures 3 to 5 shown, a flow sensor 103 is further arranged on the rod frame 100A. The flow sensor 103 is arranged between the water pump 101 and the lower rod lower docking sleeve 100B, and the flow sensor 103 communicates the water outlet 101a and the water outlet pipe.

[0096] Further, as Figure 8 、 Figure 10 、 Figure 12 、 Figure 13As shown, there is also a groove on the outer side wall where the upper rod lower docking sleeve 400B is sleeved with the lower rod upper docking sleeve 100C. An elastically expandable and retractable elastic buckle 400B1 is arranged in the groove. The elastic buckle 400B1 compresses the spring 400B2 in the groove, so that the elastic buckle 400B1 always maintains an elastic abutting force outward to abut against the inner wall of the lower rod upper docking sleeve 100C sleeve. Correspondingly, a clamping groove for accommodating the clamping end of the elastic buckle 400B1 is arranged on the inner wall of the lower rod upper docking sleeve 100C sleeve. When the upper rod lower docking sleeve 400B is sleeved with the lower rod upper docking sleeve 100C in place, the clamping end extends into the clamping groove, further improving the stability of the sleeve connection between the upper rod lower docking sleeve 400B and the lower rod upper docking sleeve 100C. When it is necessary to separate the upper rod lower docking sleeve 400B from the lower rod upper docking sleeve 100C, a tool needs to be borrowed first to press the clamping end of the elastic buckle 400B1 from the corresponding hole (not marked in the attached drawing) of the upper rod housing 400. When the clamping end exits the clamping groove, pull the lower rod 10 and the upper rod 40 forcefully to separate the upper rod lower docking sleeve 400B from the lower rod upper docking sleeve 100C.

[0097] In the above Embodiment 1, since the rod holder 100A is installed in the cavity of the lower rod housing 100, a water pump 101, a flow sensor 103, a battery pack 120, and a control board 110 are installed on the rod holder 100A. There are no other components in the cavity of the upper rod 40 except that the lower terminal wire harness 405 of the upper rod passes through. The weight of the lower rod 10 will exceed the weight of the upper rod 40, and the center of the rod body will also be more downward. Users will feel more convenient when pushing and pulling the connecting rod by holding the handle 50. In this embodiment, only the mechanical docking of the lower rod 10 and the hinge 20 realizes the simultaneous docking of the circuit line and the water channel between the two, while the mechanical docking of the lower rod 10 and the upper rod 40, and the mechanical docking of the upper rod 40 and the handle 50 only realize the simultaneous docking of the corresponding circuit lines between the two. Coupled with the differences in the corresponding docking interfaces at the two mechanical docking locations, and the anti-fooling treatment has been done to each docking interface itself, so users will not make mistakes in docking the hinge 20, the rod body group, and the handle 50, thus avoiding the problem of incorrect installation between components and improving the installation efficiency of the equipment. Embodiment

[0098] Compared with the first embodiment described above, in the solution of this embodiment, the rod holder 100A is arranged inside the upper rod 40; there will be no problem of the rod holder 100A sliding and falling off inside the upper rod 40; the rod holder 100A arranged inside the upper rod 40 serves as a bearing and connection unit for the components inside the upper rod 40 to achieve the integrated installation of the water circuit, circuit and power supply inside the upper rod 40; the support of the rod holder 100A on the inner wall of the upper rod 40 can also increase the structural strength and rigidity of the upper rod 40. Correspondingly, the electrical connection harness and the water circuit connection pipeline that extend downward from the rod holder 100A in the cavity of the upper rod 40 need to pass through the cavity inside the entire lower rod 10. Correspondingly, the circuit harness and the water circuit pipeline connecting the hinge member 20 to the rod body will be correspondingly longer. Docking components for simultaneous electrical and water circuit docking are configured at both ends of the lower rod 10, and a docking component for simultaneous electrical and water circuit docking is configured at the lower end of the upper rod 40. Other technical details are exactly the same as those in the first embodiment and will not be elaborated here.

[0099] In this embodiment, the center of gravity of the rod body is more biased upward relative to the first embodiment. When the user holds the handle 50 and pushes and pulls the drag head 30, the overall experience will be somewhat different from that of the first embodiment, but the power supply, circuit, water circuit and control board are all integrally installed inside the rod body, reducing the overall volume of the device and improving the protection and the convenience of installation and disassembly. Embodiment

[0100] Compared with the first and second embodiments described above, in the solution of this embodiment, the rod holder 100A is arranged between the lower rod 10 and the upper rod 40; there will be no problem of the rod holder 100A sliding and falling off inside the lower rod 10 and the upper rod 40; the rod holder 100A arranged inside the lower rod 10 and the upper rod 40 serves as a bearing and connection unit for the components inside the lower rod 10 and the upper rod 40 to achieve the integrated installation of the water circuit, circuit and power supply inside the lower rod 10 and the upper rod 40; the support of the rod holder 100A on the inner walls of the lower rod 10 and the upper rod 40 can also increase the structural strength and rigidity of the lower rod 10 and the upper rod 40. Since the length of the rod holder 100A is relatively long, the length dimension of the cooperation between the rod holder 100A and the lower rod 10 and the upper rod 40 is longer than the cooperation dimension between the lower rod 10 and the upper rod 40 in the first and second embodiments, and the stability of the cooperation between the lower rod 10 and the upper rod 40 through the rod holder 100A is higher. Other technical details are exactly the same as those in the first and second embodiments described above and will not be elaborated here. Embodiment

[0101] Compared with the first, second, and third embodiments described above, in the solution of this embodiment, the number of the rod frames 100A is more than two. When the number of the rod frames 100A is set to an odd number, reference can be made to the third embodiment described above; when the number of the rod frames 100A is set to an even number, reference can be made to the first or second embodiment described above; other technical details are exactly the same as those of the first, second, and third embodiments described above, and will not be elaborated here. Embodiment

[0102] In a second aspect, the present utility model provides an embodiment of a floor washer, and the floor washer includes a mop head 30 and the connecting rod described in the first aspect. By connecting and fixing the hinge member 20, the rod body group, and the handle 50 to each other, and integrating and installing the power supply, circuit, waterway, and control board inside the rod body, the overall volume of the floor washer device is reduced, and the protection and the convenience of installation and disassembly are improved; at the same time, the connection channels between the rod body group and the hinge member accommodate the circuit lines and the waterway channels connecting the water pump and the hinge member; different from the connection between the rod body group and the hinge member, only the circuit channel connecting the water pump and the handle is accommodated in the connection channel between the rod body group and the handle. During installation, the user can correctly and adaptively install the hinge member, the rod body group, and the handle by distinguishing whether the rod body group is the end with a dual connection of the waterway and the circuit of the hinge member or the end where the rod body group is only connected to the circuit of the handle, so as to avoid the problem of incorrect installation between each component and improve the installation efficiency of the device.

[0103] The above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit the same; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacement or combination on some structures (technical features) in one or more embodiments. These modifications, replacements, 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 utility model, unless it is clearly excluded in the embodiments that the structures (technical features) in different embodiments can be replaced or combined, or this replacement or combination is contrary to the overall concept of the utility model.
