Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a connecting rod and a floor scrubber. 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. 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.

[0003] 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.

[0004] 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.

The lower rod terminal seat 100B1 is adapted and fixed to the docking port 100A1 of the rod frame 100A.

[0083] In this way, the rod assembly and the hinge 20 are detachably connected to each other through the lower rod lower docking sleeve 100B, making the connection between the hinge 20 and the rod more stable and improving the stability of the structure. At the same time, the mechanical docking, electrical connection docking, and waterway connection docking of the rod assembly and the hinge 20 can be completed by a single quick docking of the rod assembly and the hinge 20, which is efficient and convenient.

[0084] In one or some alternative embodiments, Figures 1 to 3 As shown, the connecting rod is also hinged with a tractor head 30 at the hinge head 20B of the hinge 20, and the water pump 101 in the rod body group is controlled by the handle 50 to supply water to the tractor 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, thereby performing cleaning work.

[0085] In the present application, the mechanical docking of the rod group and the hinge 20 can realize the simultaneous docking of the circuit line and the water channel between the rod group and the hinge 20; which is different from the mechanical docking of the rod group and the handle 50, which can only realize the simultaneous docking of the circuit line between the rod group and the handle 50. In addition, in combination with the difference in the corresponding docking interfaces at the two mechanical docking locations, each docking interface itself has been fool-proofed, so the user will not make a mistake in docking the hinge 20, the rod group, and the handle 50, thereby avoiding the problem of incorrect installation between the various components and improving the installation efficiency of the equipment. Moreover, when an electrical connection failure occurs, if the control panel 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 group and the hinge 20. If the display device of the handle 50 fails, then the electrical connection failure can only occur in the electrical connection failure of the circuit line between the rod group and the handle 50. If the control panel 110 reports that the flow rate of the water pump 101 is low, in addition to the possibility that the water pump 101 itself is faulty, the connection of the water channel between the rod assembly and the hinge 20 may also leak.

[0086] The following describes in detail the more detailed technical solutions of the present application in several embodiments according to the specific installation position and installation method of the rod frame 100A in the rod body group. Example

[0089] Further, such 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 the water outlet 101a and the water inlet 101b are respectively provided with a water outlet pipe and a water inlet pipe, and the water outlet pipe and the water inlet pipe respectively pass through the lower docking sleeve 100B of the lower rod, and are connected with the connecting head 20A of the hinge 20, so as to form a water channel connecting the lower rod 10 and the hinge 20.

[0090] Further, such as Figures 3 to 5 As shown, a battery pack 120 and a control board 110 are also provided on the rod frame 100A. The battery pack 120 is arranged on a side of the rod frame 100A close to the lead port 100A2; the control board 110 is threadedly connected to the fixing nut column of the rod frame 100A, and an electrode sheet group is provided on the control board 110.

The lower docking terminal 104 passes through the docking port 100A1 and the lower rod docking sleeve 100B in sequence, and after passing through the lower rod 10, it is electrically connected to the connector 20A of the hinge 20.

[0092] Further, such as Figures 3 to 5 As shown, the control board 110 is also electrically connected to the upper terminal harness 106, and the end of the upper terminal harness 106 is provided with an upper docking terminal 107.

[0094] Further, such as Figure 8 , Fig.10 , Fig.12 , Fig.13As shown, a groove is also provided on the outer side wall where the upper rod lower docking sleeve 400B and the lower rod upper docking sleeve 100C are sleeved, and an elastic buckle 400B1 that can be elastically retracted outward is provided in the groove, and the elastic buckle 400B1 compresses the spring 400B2 in the groove, so that the elastic buckle 400B1 always maintains an elastic contact force outward to contact the inner wall of the lower rod upper docking sleeve 100C.

When the upper rod lower docking sleeve 400B and the lower rod upper docking sleeve 100C are sleeved in place, the clamping end extends into the slot, 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, it is necessary to first use a tool to press the clamping end of the elastic buckle 400B1 from the corresponding hole (not marked in the drawing) of the upper rod housing 400. When the clamping end withdraws from the clamping slot, pull down the rod 10 and the upper rod 40 with force to separate the upper rod lower docking sleeve 400B from the lower rod upper docking sleeve 100C.

[0095] In the above first embodiment, since the rod frame 100A is installed in the cavity of the lower rod housing 100, the rod frame 100A is installed with a water pump 101, a flow sensor 103, a battery pack 120, and a control panel 110, and the cavity of the upper rod 40 is not equipped with any parts except for the upper rod lower terminal harness 405 passing 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 be further downward, and the user will feel lighter 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 simultaneously 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. Combined with the differences in the corresponding docking interfaces at the two mechanical docking points, each docking interface itself has been processed to prevent mistakes, so the user will not make mistakes in docking the hinge 20, the rod assembly, and the handle 50, thereby avoiding the problem of incorrect installation between the various components and improving the installation efficiency of the equipment. Example

[0096] Compared with the aforementioned embodiment 1, in the scheme of this embodiment, the rod frame 100A is arranged inside the upper rod 40; the rod frame 100A will not have the problem of sliding and falling off inside the upper rod 40; the rod frame 100A arranged inside the upper rod 40 serves as a bearing and connection unit for the internal components of the upper rod 40, so as to realize the integrated installation of the waterway, circuit and power supply inside the upper rod 40; the rod frame 100A placed inside the upper rod 40 supports the inner wall of the upper rod 40, and can also increase the structural strength and rigidity of the upper rod 40. Accordingly, the electrical connection harness and water connection pipe from the rod frame 100A in the cavity of the upper rod 40 downward need to pass through the cavity in the entire lower rod 10. Accordingly, the circuit harness and water pipe connecting the hinge 20 to the rod body will be longer. Both ends of the lower rod 10 are also configured with docking components for simultaneously docking the circuit and the water. The lower end of the upper rod 40 is configured with a docking component for simultaneously docking the circuit and the water. Other technical details are exactly the same as those in Example 1 and will not be repeated here.

[0097] In this embodiment, the center of gravity of the pole body is higher than that of the first embodiment. When the user holds the handle 50 to push and pull the tractor 30, the overall experience will be somewhat different from that of the first embodiment. However, the power supply, circuit, water circuit and control panel are integrated and installed inside the pole body, reducing the overall volume of the equipment and improving the protection and convenience of installation and disassembly. Example

[0098] Compared with the aforementioned embodiments 1 and 2, in the scheme of this embodiment, the rod frame 100A is arranged between the lower rod 10 and the upper rod 40; the rod frame 100A will not have the problem of sliding and falling off inside the lower rod 10 and the upper rod 40; the rod frame 100A arranged inside the lower rod 10 and the upper rod 40 serves as a bearing and connection unit for the internal components of the lower rod 10 and the upper rod 40, so as to realize the integrated installation of the waterway, circuit and power supply inside the lower rod 10 and the upper rod 40; the rod frame 100A placed inside the lower rod 10 and the upper rod 40 supports the inner walls of the lower rod 10 and the upper rod 40, and can also increase the structural strength and rigidity of the lower rod 10 and the upper rod 40. Since the rod frame 100A is longer in length, the length dimension of the rod frame 100A in cooperation with 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. The cooperation between the lower rod 10 and the upper rod 40 through the rod frame 100A is more stable. Other technical details are completely consistent with the aforementioned first and second embodiments and will not be repeated here. Example

[0099] Compared with the above-mentioned embodiments 1, 2 and 3, in the solution of this embodiment, the number of the rod racks 100A is more than 2. When the number of the rod racks 100A is set to an odd number, the above-mentioned embodiment 3 can be referred to; when the number of the rod racks 100A is set to an even number, the above-mentioned embodiments 1 or 2 can be referred to; other technical details are completely consistent with the above-mentioned embodiments 1, 2 and 3, and will not be repeated here. Example

[0100] In the second aspect, the utility model provides an embodiment of a floor scrubber, which includes a mop head 30 and the connecting rod described in the first aspect. The utility model reduces the overall volume of the floor scrubber equipment by connecting and fixing the hinge 20, the rod group and the handle 50 to each other, and integrating the power supply, circuit, water circuit and control panel inside the rod, thereby improving the protection and convenience of installation and disassembly; at the same time, the connection channel between the rod group and the hinge contains the circuit line and water channel connecting the water pump and the hinge; and different from the connection between the rod group and the hinge, the connection channel between the rod group and the handle only contains the circuit channel connecting the water pump and the handle. During installation, the user can correctly adapt and install the hinge, the rod group and the handle by distinguishing whether the rod group is connected to the water circuit and the circuit of the hinge, or the end of the rod group is only connected to the circuit of the handle, thereby avoiding the problem of incorrect installation between the components and improving the installation efficiency of the equipment.

[0101] The above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. 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 such replacement or combination is contrary to the overall concept of the utility model.
