Description

[0001] This application is a divisional application of Chinese Patent Application No. 202420855057.9, with an application date of April 23, 2024, and an invention title of "A Floor Washer Connecting Rod and a Floor Washer". The content is incorporated herein by reference. Technical Field

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

[0003] In the early days, the ground cleaning tools used by people were brooms, mops, floor scrubbers, etc. These tools mainly relied on manual operations by people to complete the cleaning work. With the progress of technology, people's requirements for ground cleaning tools have gradually increased. First, vacuum cleaners appeared, which rely on electric power supply and generate negative pressure to suck up garbage, dust, etc. on the ground. Classified by the cleaning means and the flow path of small and large particle garbage, this type of technology is usually classified as the air-dust circulation technology. However, due to the limitations of its working principle, the vacuum cleaner cannot clean some garbage and stains firmly attached to the ground. Therefore, a new "water-dust circulation" floor washer has emerged. The motor runs to drive the cleaning cylinder to wipe the ground, and at the same time, a water supply system and a water tank are also equipped in the floor cleaner to clean the cleaning cylinder, thus perfectly realizing the cleaning of the ground.

[0004] The prior art CN220175029U discloses a floor washer connecting rod, which includes a hollow rod body, an upper connecting component and a lower connecting component, and also includes an upper connecting housing and a lower connecting housing. The upper end of the upper connecting housing is fixedly connected to the floor washer handle, and the lower end of the lower connecting housing is fixedly connected to the floor washer head. Limiting grooves are opened on the side walls at the upper and lower ends of the rod body. When the upper and lower ends of the rod body are respectively inserted into the upper connecting housing and the lower connecting housing, the upper connecting housing and the lower connecting housing respectively extend into the upper and lower ports of the rod body. Through the corresponding cooperation of the upper connecting component, the upper connecting housing, the lower connecting component and the lower connecting housing, the upper and lower ends of the rod body are firmly connected to the floor washer handle and the head respectively.

[0005] However, for the floor washer connecting rod configured in the existing "water-dust circulation" floor washer, whether it is arranged at the bottom of the water tank or on the body of the floor washer, it inevitably occupies a large volume. At the same time, in order to supply power to the floor washer connecting rod, the floor washer connecting rod needs to be pulled far away to a transfer module that is convenient for power taking. When the user takes out or places the water tank or performs maintenance on the floor washer body, it is inevitable that water drops will fall on the transfer module for power taking of the floor washer connecting rod.

[0065] In the present utility model, ordinal numbers such as "first", "second", etc. are only used for distinction purposes and cannot be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined by "first" and "second" may explicitly or implicitly include at least one of such technical features. In the present utility model, for the convenience of description, there may be quantifier limitations such as "one", "two", "multiple", "at least one", or "several" for defining technical (structural) features. Among them, the meaning of "multiple" is at least two, that is, it can be two or more; the meaning of "at least one" and "several" is one or more corresponding technical features; quantifier limitations such as these are only for explaining the specific embodiments or the best implementation modes, and all those that do not conflict with the overall concept and purpose of the utility model should be included, unless it is clearly stated that implementation must be limited by the described quantifiers or the purpose of the utility model can be achieved.

[0066] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "setting", "connection", "fixation", "swivel connection" and the like shall be understood in a broad sense. For example, it can be either that the relative positions of components are fixed, or that there is a physically fixed connection between components.

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.

[0067] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model. The present utility model will be further described below with reference to specific embodiments, but this is not a limitation of the present utility model.

[0068] In the first aspect, as Figure 1-13 described, a floor washer connecting rod of the present utility model is used for a floor washer with a mop head. One end of it is hinged to the mop head 30. The floor washer connecting rod includes a hinge device 20, a rod body assembly and a handle 50; the hinge device 20 includes a connecting head 20A and a hinge head 20B, and the hinge head 20B is hinged to the mop head 30; the handle 50 is away from the mop head 30 and has a clamping portion 50A and a gripping portion 50B; the rod body assembly is detachably connected between the hinge device 20 and the handle 50, and a water pump 101 is provided inside the rod body assembly. Among them, the hinge device 20, the rod body assembly and the handle 50 can be quickly docked in sequence; the water channels (not marked in the attached drawings) built in the hinge device 20 and the rod body assembly are synchronously docked when the hinge device 20 and the rod body assembly are docked; the circuit lines (not marked in the attached drawings) built in the hinge device 20, the rod body assembly and the handle 50 are synchronously docked when the hinge device 20, the rod body assembly and the handle 50 are docked.

[0069] Thus, the utility model reduces the overall volume of the device by connecting and fixing the hinge device, the rod body assembly and the handle, and integrating and installing the power supply, the circuit, the water circuit and the control board inside the rod body assembly, so as to improve the protection performance and the convenience of installation, disassembly and removal. At the same time, the connection channel between the rod body assembly and the hinge device houses the circuit line and the water circuit channel connecting the water pump and the hinge device. Different from the connection between the rod body assembly and the hinge device, only the circuit channel connecting the water pump and the handle is housed in the connection channel between the rod body assembly and the handle. During installation, the user can correctly and adaptively install the hinge device, the rod body assembly and the handle by distinguishing whether the rod body assembly is the end with double connections of the water circuit and the circuit to the hinge device or the end with only the circuit connection of the rod body assembly to the handle, thus avoiding the problem of incorrect installation between components and improving the installation efficiency of the device.

[0070] In one or some alternative embodiments, as Figure 3 , Figure 4 shown, the rod body assembly includes a lower rod 10 and an upper rod 40 which are butted against each other; when the lower rod 10 and the upper rod 40 are butted, at least the built-in circuit lines of the lower rod 10 and the upper rod 40 are synchronously butted; the lower rod 10 and the upper rod 40 are hollow inside, and the rod body assembly further includes an inner bracket 100A. The inner bracket 100A has openings at both ends and is arranged inside the lower rod 10 or the upper rod 40. One end of the inner bracket 100A is provided with a lower port 100A1, and the lower port 100A1 faces the connection head 20A of the hinge device 20. The other end of the inner bracket 100A is provided with an upper port 100A2, and the upper port 100A2 is electrically connected to the handle 50.

[0071] It should be noted that there is no limitation on 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 installing the inner bracket 100A inside the rod body assembly is within the protection scope of this application. More importantly, there is no limitation on the specific number of the inner brackets 100A. The inner brackets 100A can be set to at least 2, and at least one of the inner brackets 100A can be respectively arranged inside the lower rod 10 and the upper rod 40. The technical solutions of installing at least 2 inner brackets 100A inside the rod body assembly are within the protection scope of this application.

[0072] 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 washer is working, the inner bracket placed inside the lower rod or the upper rod will not have problems of sliding and falling off; the inner bracket arranged inside the lower rod or the upper rod serves as a bearing and connecting unit for the internal components of the rod body assembly, so as to realize the integrated installation of the water circuit, the circuit and the power supply inside the rod body assembly; on the other hand, since the lower rod and the upper rod are hollow inside, the support of the inner bracket 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, thereby further increasing the rigidity of the rod body assembly while reducing the overall weight of the rod body assembly.

[0073] In one or some alternative embodiments, as Figures 3 to 5 , Figure 7 shown, a water pump 101 is provided on the inner bracket 100A, and the water pump 101 is arranged on one side of the inner bracket 100A close to the lower port 100A1; the water pump 101 is provided with a water outlet 101a and a water inlet 101b, and both the water outlet 101a and the water inlet 101b are arranged in the direction of the hinge device 20. 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 rod body assembly and communicate with the connecting head 20A of the hinge device 20 to form a water channel for communicating the rod body assembly and the hinge device 20.

[0074] In this way, a water pump is arranged on the inner bracket, and both the water outlet and the water inlet of the water pump are arranged in the direction of the hinge device, so that the water outlet pipe and the water inlet pipe connecting the water outlet, the water inlet and the hinge device can be conveniently passed through the rod body assembly and communicated with the connecting head of the hinge device, which can make the length of the water pipeline inside the rod body assembly the shortest and the connection more convenient. At the same time, a single docking of the rod body assembly and the hinge device can realize the quick docking of the water channel for communicating the rod body assembly and the hinge device.

[0075] In one or some alternative embodiments, as Figures 3 to 5As shown, a battery pack 120 and a control board 110 are further provided on the inner support 100A. The battery pack 120 is arranged on one side of the inner support 100A close to the upper port 100A2. The control board 110 is threadedly connected to a fixed nut column (not shown in the drawing) of the inner support 100A. An electrode sheet group (not shown in the drawing) is provided on the control board 110. The electrode sheet group clamps the battery pack 120. The inner support 100A and the control board 110 jointly fix the battery pack 120 to improve the integration degree of the inner support 100A. In a preferred embodiment, the battery 120 is used as a power source and placed in the rod body assembly. By providing the inner support 100A, the rod body assembly is convenient for disassembly and installation, and at the same time, it is also convenient for replacing and repairing the battery 120 component.

[0076] Further, 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 a 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.

[0077] In this way, a battery pack and a control board are provided on the inner support. Inside the rod body assembly, 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 sheet group that clamps the battery pack is provided on the control board, which can conveniently connect and fix the hinge device, the rod body assembly and the handle to each other, and integrally install the power supply, the circuit and the control board inside the rod body assembly, reduce the overall volume of the device, and improve the protection performance and the convenience of installation and disassembly. At the same time, a single docking of the rod body assembly and the hinge device can realize the quick docking of the circuit lines connected between the rod body assembly and the hinge device, and a single docking of the rod body assembly and the handle can realize the quick docking of the circuit lines connected between the rod body assembly and the handle.

[0078] In one or some alternative embodiments, as Figures 3 to 5 shown, the control board 110 is electrically connected to a lower terminal wire harness 105. A lower docking terminal 104 is provided at the end of the lower terminal wire harness 105. The lower docking terminal 104 passes through the lower port 100A1 and the rod body assembly in sequence and is electrically connected to a connection head 20A of the hinge device 20.

[0079] In one or some alternative embodiments, as Figures 3 to 5As 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. The upper docking terminal 107 passes through the upper port 100A2 and the rod body assembly in sequence, and is electrically connected to the handle 50.

[0080] In this way, a control board is provided on the inner bracket. Inside the rod body assembly, the control board is electrically connected outside the rod body assembly. The control board is electrically connected to the lower terminal harness. The lower terminal harness passes through the lower port and is electrically connected to the hinge device. The control board is electrically connected to the upper terminal harness. The upper terminal harness passes through the upper port and is electrically connected to the handle. This can quickly and conveniently dock the hinge device, the rod body assembly, and the handle with each other. At the same time, a single docking of the rod body assembly and the hinge device can achieve a quick docking of the circuit line connecting the rod body assembly and the hinge device, and a single docking of the rod body assembly and the handle can achieve a quick docking of the circuit line connecting the rod body assembly and the handle.

[0081] In one or some alternative embodiments, as Figures 3 to 5 shown, a flow sensor 103 is further provided on the inner bracket 100A. The flow sensor 103 is arranged between the water pump 101 and the lower 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.

[0082] In this way, after a flow sensor is provided inside the rod body assembly, 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 that the floor washer can work more energy-efficiently and efficiently.

[0083] In one or some alternative embodiments, as Figures 3 to 5 shown, the control board 110 is further provided with at least one temperature sensor 111. The temperature sensor 111 senses the temperature of the control board 110 and the battery pack 20, and feeds back the temperature through a signal connection to a display unit (not shown in the drawings) provided on the surface of the handle 50.

[0084] In this way, when at least one temperature sensor is provided on the control board, the control board can obtain the temperature of the battery pack and the control board in real time. Then, the control board can adjust the control strategies for the water pump and the drive motor in time according to the measured temperature data, so that the floor washer can work more energy-efficiently and efficiently.

[0085] In one or some alternative embodiments, Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 11 As shown, the hinge device 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 device 20. A connecting terminal and a water inlet interface and a 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 device 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.

[0086] In this way, the rod assembly and the hinge device 20 are detachably connected to each other through the lower rod lower docking sleeve 100B, making the connection between the hinge device 20 and the rod assembly more stable and improving the stability of the structure. At the same time, the mechanical docking, electrical connection docking, and water connection docking of the rod assembly and the hinge device 20 can be completed by a single quick docking of the rod assembly and the hinge device 20, which is efficient and convenient.

[0087] In one or some alternative embodiments, Figures 1 to 3 As shown, the floor scrubber connecting rod is also hinged with a tractor head 30 at the hinge head 20B of the hinge device 20, and the water pump 101 in the rod body assembly is controlled by the handle 50 to supply water to the tractor head 30, and the battery pack 120 in the rod body assembly is controlled by the handle 50 to supply power to the water pump 101 and the drive motor, thereby performing cleaning work.

[0088] In the present application, the mechanical docking of the rod assembly and the hinge device 20 can simultaneously achieve the simultaneous docking of the circuit line and the water channel between the rod assembly and the hinge device 20; different from the mechanical docking of the rod assembly and the handle 50, only the simultaneous docking of the circuit line between the rod assembly and the handle 50 can be achieved. Coupled with the differences in the corresponding docking interfaces at the two mechanical docking locations, each docking interface has already been anti-fooled, so users will not make wrong docking among the hinge device 20, the rod assembly, 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 can only occur in the electrical connection of the circuit line between the rod assembly and the hinge device 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 of the circuit line between the rod assembly 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 water channel between the rod assembly and the hinge device 20 may also leak.

[0096] Further, as Figures 3 to 5 shown, a battery pack 120 and a control board 110 are further provided on the inner support 100A. The battery pack 120 is arranged on one side of the inner support 100A close to the upper port 100A2; the control board 110 is threadedly connected to the fixed nut column of the inner support 100A. The control board 110 is provided with an electrode sheet group, and the electrode sheet group clamps the battery pack 120. The inner support 100A and the control board 110 jointly fix the battery pack 120.

[0097] 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. A lower docking terminal 104 is arranged at the end of the lower terminal wire harness 105. The lower docking terminal 104 sequentially passes through the lower port 100A1 and the lower rod lower docking sleeve 100B, and after passing through the lower rod 10, is electrically connected to the connector 20A of the hinge device 20.

[0098] Further, as Figures 3 to 5 shown, the control board 110 is also electrically connected to the upper terminal wire harness 106.

The other end of the upper terminal wire harness 106 is connected and sequentially passes through the upper port 100A2 and the lower rod upper docking sleeve 100C, and after passing through the lower rod 10, is electrically connected to the handle 50.

[0099] Further, as Figures 3 to 5 shown, a flow sensor 103 is further provided on the inner support 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.

[0100] Further, as Figures 3 to 5 、 Figures 7 to 11As shown, the upper rod 40 includes an upper rod housing 400 and a second connection kit; the upper rod housing 400 is hollow with openings at both ends.

[0101] Further, as Figure 8 , Figure 10 , Figure 12 , Figure 13 shown, there is also a groove on the outer side wall where the lower docking sleeve 400B of the upper rod is sleeved with the upper docking sleeve 100C of the lower rod. An elastically expandable and retractable elastic buckle 400B1 is provided 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 upper docking sleeve 100C of the lower rod. Correspondingly, a clamping groove is provided on the inner wall of the upper docking sleeve 100C of the lower rod to accommodate the clamping end of the elastic buckle 400B1. When the lower docking sleeve 400B of the upper rod is sleeved with the upper docking sleeve 100C of the lower rod in place, the clamping end extends into the clamping groove, further improving the stability of the sleeving between the lower docking sleeve 400B of the upper rod and the upper docking sleeve 100C of the lower rod. When it is necessary to separate the lower docking sleeve 400B of the upper rod from the upper docking sleeve 100C of the lower rod, 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 achieve the separation between the lower docking sleeve 400B of the upper rod and the upper docking sleeve 100C of the lower rod.

[0102] In the first embodiment above, since the inner bracket 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 inner bracket 100A. There are no other components configured in the cavity of the upper rod 40 except for the lower terminal wire harness 405 of the upper rod passing through. The weight of the lower rod 10 will exceed the weight of the upper rod 40, and the center of the rod assembly will also be more biased downward. When the user holds the handle 50 and pushes and pulls the floor washer connecting rod, it will be felt more convenient. In this embodiment, only the mechanical docking of the lower rod 10 and the hinge device 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 and the handle 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 the user will not make a docking error between the hinge device 20, the rod assembly, and the handle 50, thus avoiding the problem of incorrect installation between each component and improving the installation efficiency of the device.

[0103] Embodiment Two

[0104] Compared with the previous first embodiment, in the solution of this embodiment, the inner bracket 100A is provided inside the upper rod 40; there will be no problem of the inner bracket 100A sliding and falling off inside the upper rod 40; the inner bracket 100A provided inside the upper rod 40 serves as a bearing and connection unit for the internal components of the upper rod 40 to realize the integrated installation of the water channel, circuit, and power supply inside the upper rod 40; the support of the inner bracket 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 downward electrical connection wire harness and the water channel connection pipeline from the inner bracket 100A in the cavity of the upper rod 40 need to pass through the entire cavity of the lower rod 10. Correspondingly, the circuit wire harness and the water channel pipeline connecting the hinge device 20 to the rod assembly will be correspondingly longer. Docking components for simultaneous docking of circuits and water channels are configured at both ends of the lower rod 10, and docking components for simultaneous docking of circuits and water channels are 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.

[0105] In this embodiment, the center of gravity of the rod assembly will be more biased upward compared to the first embodiment. When the user holds the handle 50 and pushes and pulls the mop head 30, the overall experience will be somewhat different from that of the first embodiment, but the power supply, circuit, water channel, and control board are all integrally installed inside the rod assembly, reducing the overall volume of the device and improving the protection and the convenience of installation and disassembly.

[0106] Embodiment Three

[0107] Compared with the first and second embodiments described above, in the solution of this embodiment, the inner bracket 100A is disposed between the lower rod 10 and the upper rod 40; there will be no problem of the inner bracket 100A sliding and falling off inside the lower rod 10 and the upper rod 40; the inner bracket 100A disposed inside the lower rod 10 and the upper rod 40 serves as a bearing and connecting unit for the components inside the lower rod 10 and the upper rod 40, so as to realize the integrated installation of the water circuit, electric circuit and power supply inside the lower rod 10 and the upper rod 40; the support of the inner bracket 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 inner bracket 100A is relatively long, the length dimension of the cooperation between the inner bracket 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 cooperation stability between the lower rod 10 and the upper rod 40 through the inner bracket 100A is higher. Other technical details are completely the same as those in the first and second embodiments described above, and will not be elaborated here.

[0108] Embodiment Four

[0109] Compared with the first, second and third embodiments described above, 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 third embodiment described above can be referred to; when the number of the inner brackets 100A is set to an even number, the first or second embodiment described above can be referred to; other technical details are completely the same as those in the first, second and third embodiments described above, and will not be elaborated here.

[0110] Embodiment Five

By connecting and fixing the hinge device 20, the rod body assembly and the handle 50 to each other, and integrating and installing the power supply, electric circuit, water circuit and control board inside the rod body assembly, the overall volume of the device is reduced, and the protection and the convenience of installation and disassembly are improved; meanwhile, the connection channels between the rod body assembly and the hinge device accommodate the circuit lines and water channels connecting the water pump and the hinge device; different from the connection between the rod body assembly and the hinge device, only the circuit channel connecting the water pump and the handle is accommodated in the connection channel between the rod body assembly and the handle. During installation, the user can correctly adapt and install the hinge device, the rod body assembly and the handle by distinguishing whether the rod body assembly is the end with double water and electric circuit connections with the hinge device or the end with only electric circuit connection between the rod body assembly and the handle, so as to avoid the problem of incorrect installation between each component and improve the installation efficiency of the device.

[0112] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than 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 recorded in the foregoing embodiments, or perform equivalent replacements or combinations on some structures (technical features) in one or more embodiments, and these modifications, replacements or combinations do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model, unless the possibility of replacing or combining the structures (technical features) in different embodiments is explicitly excluded in the embodiments, or this replacement or combination is contrary to the overall concept of the utility model.
