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 respectively extend into the upper and lower ports of the rod body, and the upper connecting assembly, the upper connecting shell, the lower connecting assembly and the lower connecting shell correspond to each other, so that the upper and lower ends of the rod body are respectively firmly connected to the handle of the floor scrubber and the mop head.

[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.

[0066] In this way, the utility model reduces the overall volume of the device and improves the protection and convenience of installation and disassembly by connecting and fixing the hinge body, the rod body and the handle to each other, and integrating the power supply, circuit, water circuit and control panel inside the rod body; at the same time, the connection channel between the rod body and the hinge body accommodates the circuit line and the water channel connecting the water pump and the hinge body; and different from the connection between the rod body and the hinge body, the connection channel between the rod body and the handle only accommodates the circuit channel connecting the water pump and the handle. During installation, the user can correctly adapt and install the hinge body, the rod body and the handle by distinguishing whether it is the end of the rod body that is connected to the water channel and the circuit of the hinge body, or the end of the rod body that 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.

[0067] In one or some alternative embodiments, Figure 3 , Figure 4 As shown, the hinge body 20 includes a connecting head 20A and an articulated head 20B, and the articulated head 20B is hinged to the tractor head 30. The handle 50 is away from the tractor head 30, and has a clamping portion 50A and a gripping portion 50B.

[0068] In one or some alternative embodiments, Figure 3 , Figure 4As shown, the rod body includes a lower rod 10 and an upper rod 40 that are connected to each other; when the lower rod 10 and the upper rod 40 are connected, at least the built-in circuit lines of the lower rod 10 and the upper rod 40 are synchronously connected; the lower rod 10 and the upper rod 40 are hollow inside, and the rod body also includes an inner bracket 100A, which has openings at both ends and is arranged in the lower rod 10 or the upper rod 40; a lower port 100A1 is provided at one end of the inner bracket 100A, and the lower port 100A1 faces the connecting head 20A of the hinge body 20; an upper port 100A2 is provided at the other end of the inner bracket 100A, and the upper port 100A2 is connected to the wire of the handle 50.

[0069] It should be noted that it is not limited here whether the inner bracket 100A is installed inside the lower rod 10 or the upper rod 40. Of course, the inner bracket 100A can also be installed between the lower rod 10 and the upper rod 40. As long as the technical solution of the inner bracket 100A is installed inside the rod body, it is within the protection scope of this application. It should also be noted that the specific number of inner brackets 100A is not limited here. The inner bracket 100A can be set to at least 2, and at least one inner bracket 100A can be respectively set in the lower rod 10 and the upper rod 40. The technical solution of at least 2 inner brackets 100A installed inside the rod body is within the protection scope of this application.

[0070] In this way, the inner bracket is adapted to the hollow shape of the lower rod or the upper rod, so that when the floor scrubber is working, the inner bracket placed inside the lower rod or the upper rod will not slide or fall off; the inner bracket arranged inside the lower rod or the upper rod serves as a bearing and connection unit for components inside the rod body, so as to realize the integrated installation of waterways, circuits and power supplies in the rod body; on the other hand, since the lower rod and the upper rod are hollow inside, the inner bracket placed inside the lower rod and / or the upper rod supports the inner walls of the lower rod and the upper rod, and can also increase the structural strength and rigidity of the lower rod and / or the upper rod, thereby further increasing the rigidity of the rod body while reducing the overall weight of the rod body.

[0072] In this way, a water pump is arranged on the inner bracket, and the water outlet and water inlet of the water pump are arranged toward the direction of the hinge body, so that the water outlet pipe and water inlet pipe connecting the water outlet, water inlet and hinge body can be conveniently passed through the rod body respectively and connected with the connecting head of the hinge body, so that the length of the water pipeline inside the rod body can be minimized and the connection is more convenient. At the same time, a single docking of the rod body and the hinge body can realize the rapid docking of the water channel connecting the rod body and the hinge body.

[0073] In one or some alternative embodiments, Figures 3 to 5 As shown, a battery pack 120 and a control board 110 are also provided on the inner bracket 100A, and the battery pack 120 is provided on a side of the inner bracket 100A close to the upper port 100A2; the control board 110 is threadedly connected to a fixing nut column (not marked in the drawings) of the inner bracket 100A, and an electrode sheet group (not marked in the drawings) is provided on the control board 110, and the electrode sheet group clamps the battery pack 120, and the inner bracket 100A and the control board 110 jointly fix the battery pack 120 to improve the integration of the inner bracket 100A; in a preferred embodiment, the battery 120 is placed in the rod body as a power source, and the inner bracket 100A is provided so that the rod body is convenient for disassembly and installation, and the battery 120 is also convenient for replacement and maintenance.

[0074] Furthermore, the battery pack 120 includes more than two batteries connected in series and then in parallel, the control board 110 is electrically connected to the water pump 101 and the drive motor (not shown in the drawings) that drives the cleaning roller in the tractor to rotate, and the control board 110 is electrically connected to the charging port (not shown in the drawings) of the handle 50. When the control board 110 controls the operation of the water pump 101 and the drive motor, the battery pack 120 is in an outward discharge state, and when the external power adapter is electrically connected to the charging port, the external power adapter charges the battery pack 120 through the control board 110.

[0075] In this way, a battery pack and a control board are arranged on the inner bracket, and in the rod body, the control board is electrically connected to the water pump and a driving motor in the tractor that drives the cleaning roller to rotate, and an electrode sheet group for clamping the battery pack is arranged on the control board, so that the hinge body, the rod body and the handle can be conveniently connected and fixed to each other, and the power supply, the circuit and the control board are integrated and installed inside the rod body, thereby reducing the overall volume of the equipment and improving the protection and convenience of installation and disassembly; at the same time, a single docking of the rod body with the hinge body can realize the rapid docking of the circuit line connected to the hinge body, and a single docking of the rod body with the handle can realize the rapid docking of the circuit line connected to the rod body with the handle.

[0076] In one or some alternative embodiments, Figures 3 to 5 As shown, the control board 110 is electrically connected to the lower terminal harness 105, and the end of the lower terminal harness 105 is provided with a lower docking terminal 104. The lower docking terminal 104 passes through the lower port 100A1 and the rod body in sequence, and is electrically connected to the connector 20A of the hinge body 20.

The upper docking terminal 107 passes through the upper port 100A2 and the rod body in sequence, and is electrically connected to the handle 50.

[0078] In this way, a control board is arranged on the inner bracket, and inside the rod body, the control board is electrically connected to the outside of the rod body, the control board is electrically connected to the lower terminal wiring harness, the lower terminal wiring harness passes through the lower port and is electrically connected to the hinge body, the control board is electrically connected to the upper terminal wiring harness, and the upper terminal wiring harness passes through the upper port and is electrically connected to the handle, so that the hinge body, the rod body and the handle can be quickly docked with each other conveniently, and a single docking of the rod body and the hinge body can realize a quick docking of the circuit line connected to the rod body and the hinge body, and a single docking of the rod body and the handle can realize a quick docking of the circuit line connected to the rod body and the handle.

[0079] In one or some alternative embodiments, Figures 3 to 5 As shown, a flow sensor 103 is also provided on the inner bracket 100A, and the flow sensor 103 is arranged between the water pump 101 and the lower port 100A1. The flow sensor 103 is connected to the water outlet 101a and the water outlet pipe to measure the flow in the water outlet 101a. Further, the flow sensor 103 is also electrically connected to the control board 110, and the flow sensor 103 transmits the real-time flow data of the water outlet 101a of the water pump 101 back to the control board 110, and the control board 110 can adjust the control strategy of the water pump 101 in real time according to the received flow data.

[0080] In this way, after the flow sensor is arranged in the rod body, the control board can adjust the control strategy of the water pump in real time according to the flow data of the water pump, so as to make the floor scrubber more energy-saving and efficient.

[0081] In one or some alternative embodiments, Figures 3 to 5As shown, the control board 110 is also provided with at least one temperature sensor 111, which senses the temperature of the control board 110 and the battery pack 20, and feeds back to a display unit (not shown in the drawing) provided on the surface of the handle 50 through a signal connection.

[0082] In this way, the control panel is also provided with at least one temperature sensor, which allows the control panel to obtain the temperature of the battery pack and the control panel in real time, and can use the temperature data measured in real time by the control panel to timely adjust the control strategy of the water pump and the drive motor, so as to make the floor scrubber more energy-saving and efficient.

[0083] In one or some alternative embodiments, Figure 4 , Figure 5 , Figure 7 , Fig. 9 , Fig.11 As shown, the hinge body 20 includes a connecting head 20A and a hinge head 20B. A connecting terminal (not marked in the drawings) is provided at the end of the connecting head 20A of the hinge body 20. Connecting terminals, water inlet interface and water outlet interface are provided inside the connecting terminal. The lower rod lower docking sleeve 100B is sleeved on the connecting head 20A of the hinge body 20. The connecting end of the connecting head 20A extends into the lower rod lower terminal seat 100B1 of the lower rod lower docking sleeve 100B. The lower rod lower terminal seat 100B1 is adapted and fixed to the lower port 100A1 of the inner bracket 100A.

[0084] In this way, the rod body and the hinge body 20 are detachably connected to each other through the lower rod lower docking sleeve 100B, making the connection between the hinge body 20 and the rod body more stable and improving the stability of the structure. At the same time, through a single quick docking of the rod body and the hinge body 20, the mechanical docking, electrical connection docking, and water connection docking of the rod body and the hinge body 20 can be completed, which is efficient and convenient.

[0085] 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 body 20, and the water pump 101 in the rod body is controlled by the handle 50 to supply water to the tractor head 30, and the battery pack 120 in the rod body is controlled by the handle 50 to supply power to the water pump 101 and the drive motor, thereby performing cleaning work.

[0086] In the present application, the mechanical docking of the rod body and the hinge body 20 can realize the simultaneous docking of the circuit line and the water channel between the rod body and the hinge body 20; which is different from the mechanical docking of the rod body and the handle 50, which can only realize the simultaneous docking of the circuit line between the rod body 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 body 20, the rod body, 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 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 and the hinge body 20. If the display device of the handle 50 has a display failure, then the electrical connection failure can only occur in the electrical connection failure of the circuit line between the rod body 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 body and the hinge body 20 may also leak.

[0099] In the above embodiment 1, since the inner bracket 100A is installed in the cavity of the lower rod housing 100, the water pump 101, the flow sensor 103, the battery pack 120, and the control board 110 are installed on the inner bracket 100A, and the cavity of the upper rod 40 is not equipped with any parts except that the upper rod lower terminal harness 405 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 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 body 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 and the handle 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 users will not make mistakes in docking the hinge body 20, the rod body, and the handle 50, thereby avoiding the problem of incorrect installation between the various components and improving the installation efficiency of the equipment. Example

[0100] Compared with the aforementioned embodiment 1, in the scheme of this embodiment, the inner bracket 100A is arranged inside the upper rod 40; the inner bracket 100A will not have the problem of sliding and falling off inside the upper rod 40; the inner bracket 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 inner bracket 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. Correspondingly, the electrical connection harness and water connection pipes from the inner bracket 100A in the cavity of the upper rod 40 downward need to pass through the cavity in the entire lower rod 10. Correspondingly, the circuit harness and water pipes connecting the hinge body 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.

[0101] In this embodiment, the center of gravity of the rod 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 is somewhat different from that of the first embodiment. However, the power supply, circuit, water circuit and control panel are integrated and installed inside the rod body, reducing the overall volume of the equipment and improving the protection and convenience of installation and disassembly. Example

[0102] Compared with the aforementioned embodiments 1 and 2, in the scheme of this embodiment, the inner bracket 100A is arranged between the lower rod 10 and the upper rod 40; the inner bracket 100A will not have the problem of sliding and falling off in the lower rod 10 and the upper rod 40; the inner bracket 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 in the lower rod 10 and the upper rod 40; the inner bracket 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 inner bracket 100A is longer in length, the length dimension of the inner bracket 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 embodiments one and two. The cooperation between the lower rod 10 and the upper rod 40 through the inner bracket 100A is more stable. Other technical details are exactly the same as those in the aforementioned embodiments one and two and will not be repeated here. Example

[0103] Compared with the above-mentioned embodiments 1, 2 and 3, in the solution of this embodiment, the number of the inner brackets 100A is more than 2. When the number of the inner brackets 100A is set to an odd number, the above-mentioned embodiment 3 can be referred to; when the number of the inner brackets 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

[0104] 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 connects and fixes the hinge body 20, the rod body and the handle 50 to each other, and integrates the power supply, circuit, water circuit and control panel inside the rod body, thereby reducing the overall volume of the device and improving the protection and convenience of installation and disassembly; at the same time, the connection channel between the rod body and the hinge body contains the circuit line and water channel connecting the water pump and the hinge body; and different from the connection between the rod body and the hinge body, the connection channel between the rod body 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 body, the rod body and the handle by distinguishing whether the rod body is connected to the water circuit and the circuit of the hinge body, or the end of the rod body 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.

[0105] 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.
