Description

Technical Field

[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.

When the connecting sleeve 400B and the docking sleeve 100C are disconnected by the above method, the first circuit connector 107 is disconnected from the second circuit connector 401, that is, the connecting sleeve 400B and the docking sleeve 100C can be mechanically and electrically disconnected simultaneously, which is convenient and quick to use.

[0083] In the present application, by providing the connection sleeve 400B, rapid docking with the docking sleeve 100C can be achieved to ensure a good connection effect. While the second rod body 400 and the first rod body 100 are connected, the electrical connection between the first circuit connector 107 and the second circuit connector 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 second rod body 400 and the first rod body 100 can be achieved at the same time.

It should be further noted that the specific number of the inner bracket 100A is not limited here, and the inner bracket 100A can be set to at least 2, and at least one inner bracket 100A can be respectively arranged in the first rod body 100 and the second rod body 400.

[0089] Further, taking the inner bracket 100A disposed on the first rod body 100 as an example for explanation, the inner bracket 100A should be adapted to the hollow shape of the first rod body 100 so that when the cleaning device is working, the inner bracket 100A disposed inside the first rod body 100 will not have the problem of sliding or falling off; the inner bracket 100A disposed inside the first rod body 100 serves as a bearing and connection unit for the internal components of the rod body assembly, and can realize the integrated installation of the water channel, circuit line and power supply in the rod body assembly (which will be described in detail later). Since the first rod body 100 is hollow inside, the inner bracket 100A disposed inside the first rod body 100 supports the inner wall of the first rod body 100 to increase the structural strength and rigidity of the first rod body 100, thereby further increasing the rigidity of the rod body assembly while reducing the overall weight of the rod body assembly.

[0090] In a specific embodiment, see Figure 3 , Figure 8 and Fig. 9 The rod assembly further includes a water pump 101 disposed on the inner 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 inner 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 rod assembly and the tractor 30.

[0091] In the present application, a water pump 101 is arranged on the inner 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 rod body assembly and make the connection more convenient. At the same time, a single docking of the first rod body 100 and the hinge rod 20 can achieve quick docking of the water channel.

[0092] In a specific embodiment, see Figure 3 , Figure 8 and Fig. 9 The rod assembly also includes a power supply 120 and a control mainboard 110 provided on the inner bracket 100A. The power supply 120 is provided near the upper port 100A2 of the inner bracket 100A, and the power supply 120 may include more than two batteries connected in series and then in parallel. The control mainboard 110 may be threadedly connected to the inner bracket 100A through a fixing nut column (not shown in the figure), and the control mainboard 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 mainboard 110 is electrically connected to the power supply 120. In the process of the control mainboard 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 mainboard 110, and the electrode sheet group clamps the power supply 120. The inner bracket 100A and the control mainboard 110 may jointly fix the power supply 120 to improve the integration of the inner bracket 100A.

[0093] Furthermore, the handheld component 50 is provided with a charging port (not shown in the figure), which is electrically connected to the control motherboard 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 motherboard 110.

[0094] In the present application, after the handheld assembly 50, the second rod body 400, the first rod body 100, and the hinge rod 20 are connected and fixed in sequence, the power supply 120 and the control mainboard 110 are integrated and installed inside the rod assembly, reducing the overall volume of the device to improve protection and convenience of installation and disassembly. At the same time, a single docking of the first rod body 100 and the hinge rod 20 can realize a quick docking of the circuit lines between the two, and a single docking of the second rod body 400 and the handheld assembly 50 can realize a quick docking of the circuit lines between the two.

[0095] In a specific embodiment, see Figure 2 and Figure 3 The control mainboard 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 mainboard 110 is also electrically connected to the second wire 106, and the second wire 106 is electrically connected to the handheld component 50.

[0096] In this way, a control main board 110 is arranged on the inner bracket 100A, and the control main board 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 handheld component 50, so that the hinge rod 20, the second rod body 400, the first rod body 100 and the handheld component 50 can be quickly connected to each other, and the circuit line can be quickly connected, so that the components of the rod body assembly (the hinge rod 20, the first rod body 100, the second rod body 400 and the handheld component 50) can be quickly connected by a single connection to realize the connected circuit lines inside each component.

[0097] In a specific embodiment, see Figure 2 , Figure 3 , Figure 8 and Fig. 9 , 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, 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 mainboard 110, and the flow sensor 103 transmits the real-time measured flow data of the water outlet 101a back to the control mainboard 110, and the control mainboard 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 more efficient.

[0098] In a specific embodiment, see Figure 3At least one temperature sensor 111 is also provided on the inner bracket 100A. The temperature sensor 111 is used to sense the temperature of the water pump 101 and the power supply 120, and is fed back to the display panel provided in the handheld 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 main board 110 can adjust the control strategy of the water pump 101 and the drive motor in time, so that the floor scrubber can work more energy-efficiently and efficiently.

[0099] In a specific embodiment, see Figure 2 and Figure 3 The second rod body assembly 10 also includes a coupling sleeve 100B disposed on the first rod body 100. The coupling sleeve 100B is hollow inside, and a snap-on seat 100B1 is disposed on the upper end of the coupling sleeve 100B. The end of the connecting portion 20A of the hinge rod 20 is provided with a snap-on 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 inner bracket 100A is disposed in the first rod body 100 and the coupling sleeve 100B is sleeved on the connecting portion 20A of the hinge rod 20, the end of the connecting portion 20A extends into the coupling 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 snap-on docking portion is snap-on with the snap-on seat 100B1.

[0100] Furthermore, a fastening screw (not shown in the figure) is provided on the coupling sleeve 100B, through which the coupling sleeve 100B and the first rod body 100 are threadedly connected, thereby realizing a detachable connection between the coupling sleeve 100B and the first rod body 100, which is reliable and easy to install or disassemble. The fastening screw can connect the coupling sleeve 100B and the first rod body 100 axially, and after fastening, the fastening screw will remain in the first 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 rod body assembly and even the cleaning device.

[0101] The combination sleeve 100B realizes the detachable connection between the first rod body 100 and the hinge rod 20, making the connection between the hinge rod 20 and the first rod body 100 more stable and improving the stability of the structure. At the same time, the mechanical connection, electrical connection and water connection of the first rod body 100 and the hinge rod 20 can be completed by a single quick connection between the first rod body 100 and the hinge rod 20, which is efficient and convenient.

[0102] In this application, see Figures 1 to 4The second rod body 400 and the first rod body 100 are detachably connected between the hinge rod 20 and the handheld component 50, and the water pump 101, the control main board 110 and the power supply 120 are integrated and installed by setting the inner bracket 100A. The handheld component 50 controls the water pump 101 to supply water to the tractor 30, and controls the power supply 120 to supply power to the water pump 101 and the driving motor to perform cleaning work.

[0103] When the handheld component 50, the second rod body 400, the first rod body 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 first rod body 100, the second rod body 400 and the handheld component 50 can be connected synchronously. The present application can realize that the handheld component 50, the second rod body 400, the first rod body 100 and the hinge rod 20 are connected and fixed to each other, and the power supply 120, the control mainboard 110, the water channel and the circuit line are integrated and installed inside the entire rod body component, reducing the overall volume of the equipment and improving the protection and convenience of installation and disassembly.

[0104] The following is divided into different embodiments according to the specific installation position of the inner bracket 100A, and the differences in the installation positions of the components related to the inner bracket 100A in different embodiments are described in detail.

[0105] Embodiment 1

[0106] See also Figure 2 and Figure 3 The first rod body 100 is provided with an inner cavity, the inner bracket 100A is provided in the inner cavity of the first rod body 100, and a coupling sleeve 100B is provided at the lower end of the first rod body 100. The lower port 100A1 of the inner bracket 100A is connected with the coupling sleeve 100B. Specifically, a clamping seat 100B1 is provided at the upper end of the coupling sleeve 100B, and the clamping seat 100B1 is adapted to the lower port 100A1 of the inner bracket 100A, and the clamping seat 100B1 can be adapted to connect with the lower port 100A1 of the inner bracket 100A.

[0107] See also Figure 3-Figure 5The docking portion 400B4 of the connecting sleeve 400B is provided with only one connecting cavity 400B7, in which the second circuit connector 401 is accommodated. In order to form a complete circuit line, a third wire 402 is provided in the second rod body 400 for electrically connecting the second circuit connector 401 and the handheld assembly 50. The control main board 110 installed on the inner 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 first circuit connector 107. When the handheld component 50, the second rod body 400, the first rod body 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 first circuit connector 107 is electrically connected to the second circuit connector 401, so that the second wire 106 connector is electrically connected to the first circuit connector 107, the second circuit connector 401, the third wire 402 in sequence, and is electrically connected to the handheld component 50.

[0108] In this embodiment, see Figure 1 , Figure 2 and Figure 3 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 rod body assembly and the tractor 30.

[0109] See also Figure 3 , Figure 5 and Figure 6 In order to achieve the installation stability of the inner bracket 100A, a joint seat 100C1 is provided on the side of the docking sleeve 100C facing the inner bracket 100A, and the joint seat 100C1 can be adapted and connected with the upper port 100A2 of the inner bracket 100A.

[0110] In this embodiment, see Figure 3 Since the inner bracket 100A is installed in the inner cavity of the first rod body 100, the inner cavity of the second rod body 400 is not equipped with other components except the third wire 402. The weight of the first rod body 100 will exceed the weight of the second rod body 400, so that the overall center of gravity of the rod body assembly is biased downward, and the user will feel lighter when pushing and pulling the tractor 30 by holding the handheld assembly 50.

[0111] In this embodiment, the mechanical docking of the first rod body 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 first rod body 100 and the second rod body 400, and the mechanical docking of the second rod body 400 and the handheld component 50 only realize the corresponding synchronous docking of the circuit line between the two. In accordance with 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 first rod body 100, the second rod body 400, and the handheld component 50, thereby avoiding the problem of incorrect installation between the components and improving the installation efficiency of the equipment.

[0112] Embodiment 2

[0113] Compared with the aforementioned embodiment 1, in this embodiment, the inner bracket 100A is arranged in the inner cavity of the second rod body 400. The connection sleeve 400B and the docking sleeve 100C need to be adjusted. They are slightly different from the embodiment 1. The docking portion 400B4 of the connection sleeve 400B is provided with two independent connection chambers 400B7, one of which is used to accommodate the second 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 connection chambers 400B7 can ensure the separation of water and electricity, and have high safety. Correspondingly, the docking sleeve 100C is provided with two independent docking chambers 100C3, one of which is provided corresponding to the connection chamber 400B7 accommodating the second circuit connector 401, and is used to accommodate the first circuit connector 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.

[0114] The circuit line and water channel of this embodiment are also slightly different from those of the above-mentioned embodiment 1. The control mainboard 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 first rod body 100 in turn, and is electrically connected to the connecting portion 20A of the hinge rod 20; the control mainboard 110 is directly electrically connected to the handheld component 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 first rod body 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 arranged at the lower end of the inner bracket 100A need to pass through the entire cavity of the first rod body 100, and accordingly, the circuit harness and water pipeline connecting the hinge rod 20 will be longer accordingly. Other technical details are completely consistent with the embodiment 1, and will not be repeated here.

[0115] In this embodiment, the center of gravity of the rod assembly is higher than that of the first embodiment, and when the user holds the handheld assembly 50 to push and pull the tractor 30, the user experience is somewhat different from that of the first embodiment. The first and second embodiments both integrate the power supply 120, the circuit line, the water channel and the control mainboard 110 inside the rod assembly, making full use of the internal volume of the rod assembly. Compared with the method of arranging these components outside the rod assembly, the external structure of the rod assembly can be more simple, which can ensure that the 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.

[0116] Embodiment 3

[0117] Compared with the aforementioned first and second embodiments, in the solution of this embodiment, the inner bracket 100A is arranged between the second rod body 400 and the first rod body 100; since the length of the inner bracket 100A is longer, compared with the first and second embodiments, the length dimension of the inner bracket 100A cooperating with the second rod body 400 and the first rod body 100 will be longer, and the second rod body 400 and the first rod body 100 can cooperate more stably through the inner bracket 100A. Other technical details are completely consistent with the aforementioned first and second embodiments, and will not be repeated here.

[0118] 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 this replacement or combination is contrary to the overall concept of the utility model.
